Gone are the days when dietary restrictions meant missing out on festive favorites. Our vegan scalloped potatoes recipe delivers all the indulgent flavor and texture you crave, making it the perfect addition to any holiday feast or special occasion. It’s a culinary triumph that will have even the most discerning palates asking for seconds!
What Are Scalloped Potatoes, and Why Make Them Dairy-Free & Gluten-Free?
Traditional scalloped potatoes are renowned for their layers of thinly sliced potatoes baked in a rich, creamy white sauce, often featuring an abundance of flour, butter, milk, and cheese. While undeniably delicious, these ingredients pose challenges for individuals with gluten or dairy allergies, lactose intolerance, or those following a vegan diet. Our mission was to recreate that same deeply satisfying, comforting experience without compromising on flavor or texture, making it accessible to all.
This innovative dairy-free scalloped potatoes recipe skillfully mimics the cheesy, velvety sauce of its traditional counterpart by using a brilliant combination of unsweetened almond milk, a touch of dairy-free yogurt for tang and creaminess, and nutritional yeast for that unmistakable savory, umami “cheese” flavor. Thinly sliced potatoes are lovingly layered with perfectly caramelized onions in a baking dish, then enveloped in this exquisite dairy-free cream sauce and baked until golden and bubbling. The result is a truly impressive side dish that offers all the luxuriousness of au gratin potatoes, completely free from milk and any dairy products. As an added benefit, this exceptional recipe is also completely gluten-free, making it a truly inclusive dish for your holiday table or any special meal.
Key Ingredients for Unforgettable Dairy-Free Scalloped Potatoes
Crafting the perfect dairy-free and gluten-free scalloped potatoes requires a few star ingredients. Each component plays a crucial role in achieving the desired creamy texture and rich flavor profile without any animal products or gluten.
- Gluten-Free Baking Flour: This is essential for thickening the creamy sauce and binding the sautéed onion mixture. For a truly gluten-free experience, opt for a high-quality gluten-free baking flour blend. My top recommendation is Bob’s Red Mill 1:1 All-Purpose Flour, known for its consistent performance in baking and cooking. If gluten isn’t a concern for you, feel free to substitute with regular all-purpose flour.
- Russet Potatoes: The humble russet potato is a perfect choice for scalloped potatoes. Its high starch content helps create a light, fluffy, and creamy texture when cooked, absorbing the flavors of the sauce beautifully. Russets also have a wonderfully mild flavor that doesn’t overpower the other ingredients. As an alternative, buttery Yukon Gold potatoes also work exceptionally well, lending a slightly richer flavor and smoother texture. The key is to slice your potatoes as thinly and uniformly as possible for even cooking and a beautiful layered presentation.
- Unsweetened Plant-Based Milk: This forms the base of our luscious dairy-free cream sauce. Unsweetened almond milk is an excellent choice as it provides a neutral, subtle flavor that allows the other ingredients to shine. You can also successfully use other unsweetened plant milks like cashew milk, soy milk, or oat milk, depending on your preference and what you have on hand. It’s crucial to choose unsweetened varieties to avoid an overly sweet outcome. I generally advise against using coconut milk, as its strong flavor can be overpowering and its heavier consistency might make the sauce too dense for this particular dish.
- Unsweetened Dairy-Free Yogurt: A secret ingredient that adds incredible depth and tang to our creamy sauce, mirroring the complexity often found in traditional cheesy sauces. Be sure to select an unsweetened plain dairy-free yogurt, such as cashew or almond yogurt, to ensure it blends seamlessly with the savory profile of the dish. This ingredient is key to achieving that rich, authentic scalloped potato flavor.
- Nutritional Yeast: A cornerstone of vegan cooking, nutritional yeast is a deactivated yeast product with a distinctive nutty, savory, and wonderfully cheesy flavor. It’s absolutely perfect for imparting that umami richness to dairy-free and vegan recipes, making you forget there’s no actual cheese. You can typically find it in the baking aisle near active-dry yeast or in the natural foods section of most grocery stores. If you find yourself without it, or simply prefer an alternative, you can refer to my guide on nutritional yeast substitutes, or you may choose to omit it, though it does contribute significantly to the overall flavor.
- Aromatics and Seasonings: Don’t underestimate the power of caramelized onions and minced garlic. Sautéing these until golden sweetens them and builds a foundational layer of flavor for the entire dish. Dried thyme adds a classic, herbaceous note that complements potatoes beautifully, while sea salt, ground black pepper, and a touch of smoked paprika round out the seasoning, adding warmth and a hint of smoky depth.

Step-by-Step Guide: Crafting Your Creamy Scalloped Potatoes
Making these dairy-free and gluten-free scalloped potatoes is a straightforward process, designed for ease and delicious results. Follow these simple steps for a truly memorable dish.
Step One: Prepare and Sauté Aromatics. Begin by preheating your oven to 425°F (220°C). Lightly spray an 8×11-inch baking dish with nonstick cooking spray and set it aside. Next, heat the olive oil in a large skillet over medium heat. Add the thinly sliced onions, dried thyme, and minced garlic. Sauté these ingredients for at least 5 minutes, stirring occasionally, until the onions have softened considerably and are just beginning to caramelize and turn golden brown. This step is crucial for developing a deep, sweet flavor base.
Step Two: Create the Sauce Base & Layer. Remove the skillet from the heat and stir in the gluten-free baking flour directly into the cooked onion mixture. Mix thoroughly until no dry flour remains and it forms a thick paste with the onions. Now, grab your prepared baking dish. Arrange one-third of your thinly sliced potatoes evenly across the bottom of the dish. Spoon half of the onion and flour mixture over this first potato layer, spreading it out. Repeat this process: add another one-third layer of potatoes, followed by the remaining half of the onion mixture. Finish with the final one-third layer of sliced potatoes on top.
Step Three: Pour the Creamy Dairy-Free Sauce. In a separate large mixing bowl, combine the unsweetened plant-based milk (almond or oat), dairy-free yogurt, sea salt, ground black pepper, and nutritional yeast. Whisk vigorously until all ingredients are thoroughly combined and the mixture is smooth. Carefully pour this flavorful dairy-free cream sauce evenly over the layered potatoes and onions in the baking dish. Gently press down on the potato layers with your hands or a spatula to ensure they are fully submerged and covered by the liquid, allowing them to absorb all the delicious flavors during baking.
Step Four: Bake to Golden Perfection. Sprinkle the top of your assembled dish with a touch of smoked paprika for extra color and a subtle smoky note. Cover the baking dish tightly with aluminum foil. Bake for an initial 30 minutes at 425°F (220°C). After this initial baking period, carefully remove the foil and reduce the oven temperature to 350°F (175°C). Continue baking uncovered for an additional 35 minutes, or until the top of the potatoes are beautifully golden brown, and the potatoes are tender when pierced with a fork. The sauce should be bubbly and thickened.
Once baked to perfection, carefully remove the vegan scalloped potatoes from the oven. Allow them to cool and set for a few minutes before serving. This brief resting period helps the sauce thicken further and makes for easier serving. These dairy-free gluten-free scalloped potatoes are best enjoyed hot, straight from the oven, offering a truly comforting and satisfying experience.
I have no doubt that your family will agree this becomes their new go-to favorite potato recipe! It’s an impeccable side dish, expertly crafted without heavy cream, whole milk, or any kind of cheese, yet it delivers on every promise of rich, creamy flavor. My family consistently requests this dish for our cherished holiday meals, from Christmas dinner to Thanksgiving, and even for other special gatherings throughout the year. It truly is a classic side dish reinvented for modern dietary needs.

Expert Tips for the Best Dairy-Free Scalloped Potatoes
Achieving the perfect creamy, tender, and flavorful scalloped potatoes is easier with a few expert insights:
- Consistent Slicing is Key: For uniform cooking and a visually appealing dish, aim for thinly and evenly sliced potatoes. A mandoline slicer is your best friend here, ideally set to 1/8-inch thickness. If using a knife, take your time to ensure consistency. A food processor fitted with a slicing disk can also be a great time-saver.
- Don’t Rush the Onions: The caramelized onions provide a crucial flavor foundation. Allow them to cook slowly over medium heat until genuinely softened and beginning to brown. This process sweetens them and deepens the overall savory profile of the dish.
- Ensure Potatoes Are Submerged: After pouring the sauce, gently press down on the potato layers. This ensures all the potato slices are adequately covered by the liquid, allowing them to soften and absorb the flavors properly as they bake, preventing dry or undercooked spots.
- Let it Rest: Resist the urge to dive in immediately after removing the dish from the oven. A short resting period (5-10 minutes) allows the sauce to thicken further and settle, resulting in cleaner servings and a more cohesive texture.
- Taste and Adjust Seasoning: Always taste your sauce mixture before pouring it over the potatoes. This gives you an opportunity to adjust the salt, pepper, or nutritional yeast to your preference, ensuring the final dish is perfectly seasoned.
Perfect Pairings for Your Holiday Spread
These dairy-free gluten-free scalloped potatoes are a star on their own, but they truly shine when paired with other complementary dishes. They are an absolute essential for any holiday menu, from Thanksgiving to Christmas dinner, offering a rich and satisfying counterpoint to lighter fare. Consider serving them alongside a succulent plant-based roast, a hearty lentil loaf, or a vibrant medley of roasted vegetables like asparagus or green beans. For a complete holiday spread, they pair wonderfully with Dairy-Free Green Bean Casserole and Gluten-Free Dairy-Free Dinner Rolls. Whether for a casual family dinner or a grand celebratory meal, these scalloped potatoes are guaranteed to be a crowd-pleaser.
Frequently Asked Questions About Dairy-Free & Gluten-Free Scalloped Potatoes
It is generally not recommended to freeze this dish. Potatoes tend to release a significant amount of water when defrosted, which can cause the texture to become soggy and mushy. They also lose some of their appealing creamy consistency. For the best flavor and texture, this dish is best enjoyed fresh or from refrigeration.
Yes, you absolutely can! To save time, you can assemble the entire dish up to 1 day in advance. Simply cover it tightly with plastic wrap or foil and refrigerate. When you’re ready to bake, remove it from the refrigerator about 30 minutes before baking to allow it to come closer to room temperature, then bake as directed in the recipe card, possibly adding an extra 5-10 minutes to the covered baking time if the dish is very cold.
While the traditional scalloped potato recipe uses white potatoes like russets or Yukon golds, you can certainly experiment with sweet potatoes for a different flavor profile. Keep in mind that sweet potatoes have a higher sugar content and a different starch structure, which will alter the taste and possibly the final texture. If you choose to use them, ensure they are sliced equally thin.
Store any leftover dairy-free scalloped potatoes in an airtight container in the refrigerator for up to 4 days. For the best reheating results, preheat your oven to 350°F (175°C). Place the leftovers in an oven-safe dish, cover it with foil, and heat until warmed through, typically 20-30 minutes. Reheating in the microwave is an option for convenience, but it may compromise the texture slightly, making it less crispy on top.
Yes, you can adapt this recipe to be nut-free. Instead of almond milk and cashew yogurt, opt for unsweetened oat milk and a plain, unsweetened soy-based or coconut-based dairy-free yogurt. Always double-check ingredient labels to ensure they are certified nut-free if severe allergies are a concern.

5 from 2 reviews
You won’t miss the dairy or gluten in this creamy recipe for Gluten-Free Dairy-Free Scalloped Potatoes. This classic holiday recipe is made vegan and allergy-friendly using gluten-free flour, milk alternatives, and dairy-free yogurt.
- Total Time: 90 minutes
- Yield: 8 servings
Ingredients
- 2 tablespoons olive oil
- 2 onions, peeled and thinly sliced
- 1/2 teaspoon dried thyme
- 2 garlic cloves, minced
- 2 tablespoons gluten-free baking flour
- 2 pounds russet potatoes, peeled and thinly sliced (about 6 large potatoes)
- 1 cup unsweetened almond milk or oat milk
- 1 cup unsweetened dairy-free yogurt
- 1 teaspoon sea salt
- 1/4 teaspoon ground black pepper
- 1/4 cup nutritional yeast
- 1/4 teaspoon smoked paprika
Instructions
- Preheat your oven to 425°F (220°C). Spray the inside of an 8-inch by 11-inch baking dish lightly with nonstick cooking spray and set aside.
- In a large skillet, heat the olive oil over medium heat. Add the sliced onions, thyme, and garlic and sauté for at least 5 minutes, or until the onions are softened and starting to brown.
- Remove the skillet from the heat and add the gluten-free baking flour to the skillet, stirring well with the onion mixture until fully incorporated.
- Grab your baking dish. Layer 1/3 of the thinly sliced potatoes evenly on the bottom of the dish. Use ½ of the onion mixture to cover these potatoes. Then repeat, adding another 1/3 of the potatoes and the rest of the onion mixture on top. Finish with the final 1/3 layer of potatoes.
- In a large mixing bowl, combine the plant-based milk, dairy-free yogurt, sea salt, black pepper, and nutritional yeast. Stir vigorously to combine, then pour this creamy mixture evenly over the potato and onion layers in the baking dish. Gently press the potatoes down with your hands or a spatula to ensure they are fully covered by the liquid.
- Sprinkle the top of your dish with smoked paprika. Cover the dish tightly with aluminum foil and bake for 30 minutes at 425°F (220°C). After the first 30 minutes of baking, remove the foil and reduce the oven temperature to 350°F (175°C) for an additional 35 minutes, or until the tops of the potatoes have turned a beautiful golden brown and are tender when pierced.
- Carefully remove the baking dish from the oven and let it cool for a few minutes before serving. This allows the sauce to thicken and set.
Recipe Notes
- If you have a mandoline, set it to 1/8-inch thickness to thinly slice your potatoes for uniform cooking. Otherwise, use a sharp knife and slice the potatoes as thinly and evenly as possible. A food processor fitted with a slicing disk also works well.
- If you are not on a gluten-free diet, you can substitute regular all-purpose flour for the gluten-free baking flour.
- If you don’t have russet potatoes, Yukon gold potatoes are an excellent alternative and will also yield a delicious, creamy result.
- Store any leftovers in an airtight container in the refrigerator for up to 4 days.
- For best results, reheat leftovers in the oven. Preheat the oven to 350°F (175°C), place the dish into the oven, and heat until the potatoes are warmed all the way through, covering with foil if needed to prevent excessive browning.
