You won’t miss the dairy or gluten in this creamy recipe for Dairy-Free & Gluten-Free Scalloped Potatoes. This classic holiday recipe is made allergy-friendly using gluten-free flour, milk alternatives, and dairy-free yogurt.

scalloped potatoes in a dish

Traditional scalloped potatoes contain lots of flour, butter, milk, and cheese. They’re rich and delicious, but I wanted to make a gluten-free and dairy-free version with the same comforting feel. In this vegan version, almond milk, dairy-free yogurt, and nutritional yeast mimic a cheesy white sauce.

Thinly sliced potatoes are layered with caramelized onions in a baking dish then topped with a creamy sauce and baked. It’s all the deliciousness of au gratin potatoes, without any of the dairy!

Dairy-free cheesy potatoes are much lower in fat than the original version but still rich and indulgent.

Why You Need This Recipe

  • It’s dairy-free & vegan but tastes rich and creamy.
  • It’s truly comfort food at its best.
  • Perfect for the holidays!

Key Ingredients

Olive oil – Heart-healthy olive oil is used to cook the sliced onions until sweet and caramelized. You can use dairy-free butter or avocado oil in its place.

Onion – When thinly sliced onions are cooked, they become sweet and flavorful.

Garlic – To save time, you can buy pre-minced garlic in a small jar. It can be found in the produce aisle near the regular garlic.

Gluten-free flour – Flour thickens the cooked onion mixture. To make these scalloped potatoes gluten-free, sub in a gluten-free baking flour in place of regular flour. My personal favorite is Bob’s Red Mill 1:1 All Purpose Flour.

Russet potatoes – Russet potatoes are perfect for scalloped potatoes. They have a light, creamy texture and mild flavor. You can also use buttery Yukon golds as well. 

Unsweetened almond milk – Unsweetened almond milk works well here because it doesn’t have an overpowering taste. You can use your favorite plant milk except I don’t recommend using coconut milk as it will be too heavy.

Dairy-free yogurt – Be sure to buy unsweetened dairy-free yogurt. Sweet yogurt won’t taste good in this savory potato recipe.

Nutritional yeast – Nutritional yeast has a nutty, cheesy flavor. It’s perfect for vegan and dairy-free recipes. It’s found in the baking aisle near active-dry yeast or in the natural foods area. 

Seasoning – Don’t forget to season! It’s the difference between an okay recipe and an amazing one.

Recipe Tips & Substitutions

  • If you have a mandoline, set it to 1/8-inch thickness to thinly slice your potatoes. Otherwise, use a knife and slice the potatoes as thinly as possible.
  • If you aren’t on a gluten-free diet, you can use all-purpose flour instead of the gluten-free flour.
  • If you don’t have russet potatoes, you can use Yukon gold potatoes instead.
  • Dairy-free scalloped potatoes taste delicious with ham. Dice up the ham and sprinkle it evenly between the layers.
  • For best results, reheat in the oven. Preheat the oven to 350 degrees Fahrenheit, and place the dish into the oven. Let the potatoes heat all the way through.

FAQs

Can I freeze dairy-free scalloped potatoes?

It’s best not to freeze this dish because potatoes release water when defrosted. They also lose some of their texture and become soggy.

Can I make it ahead of time?

You can assemble the scalloped potatoes ahead of time, cover them, and refrigerate them for up to 1 day. Remove from the refrigerator and bake as directed.
