  • 4-5 medium russet potatoes, peeled and thinly sliced

  • 1 small onion, thinly sliced

  • 3 cloves garlic, minced

  • 2 cups unsweetened dairy-free milk (e.g., almond milk, soy milk, or oat milk)

  • 2 tablespoons dairy-free butter or margarine

  • 2 tablespoons all-purpose flour (gluten-free if needed)

  • 1 teaspoon salt

  • 1/2 teaspoon black pepper

  • 1/2 teaspoon dried thyme (optional)

  • Dairy-free cheese shreds (optional, for topping)

  • Fresh chives or parsley, chopped (for garnish)


1. Preheat the Oven:

  • Preheat your oven to 375°F (190°C). Grease a baking dish (9x13 inches or similar) with dairy-free cooking spray or oil.

2. Prepare the Potatoes:

  • Peel and thinly slice the potatoes and onion. You can use a mandoline slicer for even slices, if available.

3. Make the Dairy-Free Sauce:

  • In a saucepan, melt the dairy-free butter over medium heat.

  • Add the minced garlic and sauté for about 1 minute until fragrant.

  • Stir in the all-purpose flour and cook for another 1-2 minutes to create a roux.

  • Gradually whisk in the dairy-free milk, ensuring there are no lumps. Continue to cook and whisk until the mixture thickens, about 5-7 minutes. It should have the consistency of a creamy sauce.

4. Season the Sauce:

  • Add salt, black pepper, and dried thyme (if using) to the sauce. Adjust seasonings to taste.

5. Assemble the Layers:

  • Arrange a layer of sliced potatoes in the prepared baking dish, followed by a layer of sliced onions. Repeat this layering until all the potatoes and onions are used.

6. Pour the Sauce:

  • Pour the dairy-free sauce evenly over the layered potatoes and onions.

7. Bake:

  • Cover the baking dish with aluminum foil and bake in the preheated oven for 45-50 minutes, or until the potatoes are tender.

8. Optional Topping:

  • If desired, uncover the dish and sprinkle dairy-free cheese shreds on top during the last 10-15 minutes of baking. This step is optional but adds a cheesy flavor and a golden crust.

9. Garnish and Serve:

  • Remove from the oven when the potatoes are soft and the top is nicely browned.

  • Garnish with fresh chopped chives or parsley.

10. Rest and Enjoy:

  • Allow the dairy-free scalloped potatoes to cool for a few minutes before serving. They are best enjoyed warm.

These dairy-free scalloped potatoes are a creamy and comforting side dish that's perfect for any meal. Whether you have dietary restrictions or simply prefer a dairy-free option, this recipe delivers all the flavor and richness you expect from traditional scalloped potatoes.
