How to Make White & Sweet Scalloped Potatoes

1. Preheat the oven to 375°F (190°C). Grease a baking dish with 2 tablespoons of butter, ensuring every corner is covered for that perfect golden crust.

2. Combine ingredients in a bowl. In a mixing bowl, whisk together 2 cups of heavy cream, 2 cloves of minced garlic, 1 teaspoon each of salt, black pepper, and thyme until well blended.

3. Layer the potatoes. Begin layering your 2 large white potatoes and 2 large sweet potatoes in the greased baking dish, alternating between the two for a beautiful contrast.

4. Pour the cream mixture evenly over the layered potatoes. This creamy sauce will infuse flavor and moisture into each slice as it bakes.

5. Sprinkle shredded cheese on top! Generously add 1 cup each of cheddar and mozzarella cheese over the layered potatoes for that irresistible cheesy finish.

6. Cover the baking dish with aluminum foil and bake for 45 minutes. This helps steam the potatoes, making them tender and deliciously creamy.

7. Uncover and bake again! Remove the foil and bake for an additional 15 minutes until the top is golden and bubbly, creating a delightful crust.

8. Cool for a few minutes before serving. This resting time allows flavors to settle, making each bite even more enjoyable!

Optional: Garnish with fresh thyme for an added touch of color and flavor.

Pro Tips for White & Sweet Scalloped Potatoes

Potato Thickness: Ensure your potato slices are uniformly thin (about 1/8 inch) to guarantee even cooking and a perfectly creamy texture.

Layering Technique: Alternate layers of white and sweet potatoes for a beautiful presentation and balanced flavor throughout the dish—don’t just stack them!

Cream Consistency: If using half-and-half instead of heavy cream, be mindful that it may not thicken as much; consider adding a bit of flour to achieve desired richness.

Cheese Blend: For extra flavor, try mixing different cheeses like Gruyère or Parmesan with the cheddar and mozzarella. Just avoid overloading on cheese; balance is key.

Baking Time Caution: Keep an eye on the final baking time. If the top browns too quickly, cover it loosely with foil to prevent burning while ensuring the potatoes cook through.

Resting Period: Allow your White & Sweet Scalloped Potatoes to rest for at least 10 minutes before serving. This helps set the layers and makes slicing easier!

Spicy Kick: Incorporate diced jalapeños or a pinch of cayenne pepper to bring some heat. This variation is perfect for those who love a little extra warmth in their comfort food.

Veggie Boost: Layer in thinly sliced onions or sautéed mushrooms for added depth and texture. These vegetables complement the potatoes beautifully while enhancing the overall heartiness.

Cheese Lovers: Mix in crumbled feta or gouda along with your cheddar and mozzarella for a gourmet twist. Each cheese brings its unique flavor, making every bite an adventure.

Nutty Crunch: Top with crushed walnuts or pecans before baking for an unexpected crunch that contrasts nicely with the creamy layers. This adds both texture and a nutty note that surprises the palate.
