Key Ingredients for Gluten-Free Scalloped Potatoes

Potatoes

Thinly sliced russet or Yukon Gold potatoes are the stars of this dish. They have the perfect starchy texture to create a creamy and tender result.

  • Substitute: Sweet potatoes can be used for a different flavor profile.

Gluten-Free Flour or Starch

To thicken the sauce without gluten, use gluten-free all-purpose flour, cornstarch, or potato starch. These create the creamy consistency that makes scalloped potatoes irresistible.

Milk and Cream

A combination of whole milk and heavy cream adds richness to the dish. For a dairy-free version, substitute with almond milk or coconut cream.

Cheese

Shredded cheddar cheese gives this dish its signature flavor, while Parmesan adds a salty, nutty depth. Freshly grated cheese melts better than pre-shredded varieties.

Butter

Butter adds richness and helps the gluten-free roux come together. Use a dairy-free butter alternative for a vegan-friendly dish.

Seasonings

Garlic powder, onion powder, salt, pepper, and a pinch of nutmeg enhance the flavor of the creamy sauce.

Optional Add-Ins

  • Herbs: Fresh thyme, rosemary, or parsley for garnish.
  • Veggies: Sliced onions or sautéed mushrooms add texture and flavor.
  • Protein: Add cooked bacon bits or shredded chicken for a heartier dish.

Ingredients List

  • 2 lbs potatoes (russet or Yukon Gold), peeled and thinly sliced
  • 2 tablespoons gluten-free flour or cornstarch
  • 2 cups whole milk (or dairy-free alternative)
  • 1 cup heavy cream (or coconut cream)
  • 2 tablespoons unsalted butter (or dairy-free butter)
  • 2 cups shredded cheddar cheese
  • ½ cup grated Parmesan cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • Optional: Fresh thyme or parsley for garnish

Step-by-Step Instructions to Make Gluten-Free Scalloped Potatoes

Prep the Ingredients

  1. Choose Your Potatoes: Opt for starchy potatoes like russet or Yukon Gold. These varieties create a creamy texture, while waxy potatoes may turn too firm in the dish.
  2. Peel and Slice:
    • Use a vegetable peeler to remove the potato skins.
    • Slice the potatoes into uniform ⅛-inch rounds using a sharp knife or a mandoline slicer for consistent thickness. Even slices are key to even cooking.
    • Pro Tip: Place the slices in a bowl of cold water to prevent discoloration while you prepare the sauce. This also removes excess starch, which can make the dish gummy. Be sure to pat the slices dry with a clean kitchen towel before layering.
  3. Prepare the Baking Dish: Grease a 9×13-inch baking dish with butter or non-stick spray. This prevents sticking and ensures easy serving later.
  4. Preheat Your Oven: Set your oven to 375°F (190°C) and adjust the oven rack to the middle position.

Make the Gluten-Free Sauce

  1. Melt the Butter: Place a medium-sized saucepan over medium heat. Add 2 tablespoons of butter and let it melt completely without browning.
  2. Create the Roux:
    • Sprinkle in the gluten-free flour (or cornstarch) while whisking continuously. Cook for 1–2 minutes, stirring constantly, to cook out the raw flour taste. This step is crucial for developing a smooth, creamy sauce.
    • Pro Tip: Do not let the roux burn—keep the heat moderate. A burnt roux will affect the flavor of the sauce.
  3. Add the Milk and Cream:
    • Gradually pour in the milk and cream, whisking constantly to avoid lumps. Start with a small amount of liquid, stir until smooth, and then add the rest.
    • Use warm or room-temperature milk to help the sauce thicken more evenly. Cold milk can cause lumps.
  4. Season the Sauce: Stir in garlic powder, onion powder, a pinch of nutmeg, salt, and pepper. Simmer for 3–5 minutes, whisking occasionally, until the sauce thickens to a pourable but creamy consistency.
    • Pro Tip: Taste the sauce at this stage and adjust the seasonings as needed. This is your opportunity to enhance the flavor.

Layer the Potatoes

  1. First Layer: Start by spreading a small amount of sauce evenly across the bottom of your prepared baking dish. This prevents the potatoes from sticking and ensures the bottom layer cooks evenly.
  2. Layer the Potatoes:
    • Arrange a single layer of potato slices in the dish, slightly overlapping them like shingles. This overlapping creates a cohesive texture when baked.
  3. Add Cheese and Sauce: Sprinkle a light layer of shredded cheddar cheese and Parmesan over the potatoes, then ladle some of the prepared sauce on top, ensuring it covers the potatoes evenly.
  4. Repeat: Continue layering potatoes, cheese, and sauce until you’ve used all the ingredients. End with a generous layer of cheese on top to achieve a bubbly, golden crust when baked.
    • Pro Tip: Press down gently on the layers occasionally to ensure they’re compact and the sauce distributes evenly.

Bake the Dish

  1. Cover and Bake: Cover the dish tightly with aluminum foil to trap steam and help the potatoes cook through. Bake in the preheated oven for 40 minutes.
    • Pro Tip: Use non-stick foil or spray the underside of the foil with cooking spray to prevent the cheese from sticking.
  2. Uncover and Finish Baking: Remove the foil and continue baking for an additional 15–20 minutes. This allows the top to brown and become bubbly.
  3. Test for Doneness: Insert a knife or fork into the center of the dish. If it slides through easily, the potatoes are fully cooked.

Rest and Serve

  1. Rest Before Serving: Let the dish cool for 10–15 minutes after removing it from the oven. This helps the sauce thicken further and makes it easier to serve.
  2. Garnish and Serve: Sprinkle fresh thyme, parsley, or chives over the top for a pop of color and fresh flavor. Serve warm alongside your favorite main course.

Tips for the Best Gluten-Free Scalloped Potatoes

1. Choose the Right Potatoes

  • Russet Potatoes: High starch content results in creamy, tender layers.
  • Yukon Gold Potatoes: Slightly waxy with a buttery texture, perfect for a firmer but creamy result.
  • Avoid low-starch varieties like red potatoes, as they won’t break down as nicely in the sauce.

2. Slice Thinly and Evenly

Consistent potato slices are critical for even cooking. Use a mandoline slicer to achieve perfectly thin, uniform slices.

3. Don’t Skip the Roux

A roux (butter and flour mixture) ensures the sauce thickens properly and doesn’t separate. Whisk continuously when making the roux to avoid lumps.

4. Season Generously

Potatoes absorb flavors as they bake, so make sure your sauce is well-seasoned. Taste the sauce before assembling the dish to ensure it’s flavorful.

5. Layer Thoughtfully

  • Spread the sauce and cheese evenly between layers to ensure every bite is flavorful.
  • Press down gently on each layer to compact the dish and avoid air pockets.

6. Use Freshly Shredded Cheese

Pre-shredded cheese contains anti-caking agents that can prevent it from melting smoothly. Grate your own cheese for a creamier, more cohesive dish.

7. Bake Covered and Uncovered

Cover the dish with foil for the first half of baking to trap steam and cook the potatoes evenly. Uncover it during the last 15–20 minutes to brown the top and create a bubbly, golden crust.

8. Let It Rest

Allow the dish to rest for 10–15 minutes before serving. This allows the sauce to set, making it easier to cut and serve while enhancing the flavors.

9. Customize the Dish

  • Add Veggies: Layer in sautéed onions, mushrooms, or spinach for extra flavor and nutrition.
  • Spice It Up: Add a pinch of cayenne pepper or smoked paprika to the sauce for a subtle kick.
  • Cheese Blends: Experiment with cheese varieties like gruyere, smoked gouda, or Monterey Jack for different flavor profiles.

10. Make It Ahead

Assemble the dish up to 24 hours in advance and store it covered in the refrigerator. Bring it to room temperature before baking to ensure even cooking.

11. Store and Reheat

  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • Reheat in the oven at 350°F (175°C) until warmed through. Add a splash of milk or cream to revive the sauce if needed.

What Is the Difference Between Scalloped Potatoes and Au Gratin?

Scalloped potatoes and au gratin are similar dishes but have key differences in preparation and ingredients.

Scalloped Potatoes
  • Main Ingredients: Sliced potatoes baked in a creamy sauce (typically made with milk or cream).
  • Topping: No cheese is traditionally used, although some recipes may add it for extra flavor.
  • Texture: Smooth and creamy, without a crusty topping.
