Ingredients:

For the Potatoes:

  • 2 1/2 pounds russet potatoes, thinly sliced
  • 1 small onion, finely sliced
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • Salt and black pepper to taste

For the Cheesy Sauce:

  • 1/4 cup unsalted butter
  • 1/4 cup all-purpose flour
  • 2 cups whole milk
  • 1 cup heavy cream
  • 2 cups shredded sharp cheddar cheese
  • 1 cup grated Parmesan cheese
  • 1 teaspoon garlic powder
  • Salt and black pepper to taste
  • Fresh thyme or rosemary for garnish

Instructions:

Prepping the Potatoes:

  1. Preheat your oven to 375°F (190°C). Grease a large sheet pan and set aside.
  2. In a skillet over medium heat, sauté the finely sliced onion and minced garlic in olive oil until softened. Remove from heat.
  3. Thinly slice the russet potatoes. You can use a mandoline for precision.
  4. In a large bowl, toss the potato slices with the sautéed onion and garlic mixture. Season with salt and black pepper.

Creating the Cheesy Sauce:

  1. In a saucepan over medium heat, melt the butter. Stir in the flour to create a roux, cooking for 1-2 minutes until golden.
  2. Gradually whisk in the whole milk and heavy cream, ensuring the mixture is smooth and thickened.
  3. Add the shredded cheddar and grated Parmesan cheese, stirring until melted and incorporated.
  4. Season the sauce with garlic powder, salt, and black pepper. Adjust to taste.

Layering and Baking:

  1. Arrange a layer of the seasoned potato slices on the prepared sheet pan.
  2. Pour a portion of the cheesy sauce over the potatoes, ensuring an even coating.
  3. Continue layering potatoes and sauce until all ingredients are used, finishing with a generous layer of sauce on top.
  4. Bake in the preheated oven for 45-50 minutes or until the potatoes are tender, and the top is golden brown.
  5. If desired, broil for an additional 2-3 minutes to achieve a crispy, golden crust.

Garnishing and Serving:

  1. Remove the sheet pan from the oven and let it rest for 10 minutes.
  2. Garnish with fresh thyme or rosemary for a burst of herbaceous fragrance.
  3. Slice and serve the Sheet Pan Scalloped Potatoes directly from the pan for a rustic touch.

Cooking Notes:

  • For an extra kick of flavor, you can add a pinch of cayenne pepper or nutmeg to the cheesy sauce.
  • Ensure the potato slices are evenly coated with the cheesy sauce to prevent uneven cooking.
  • If the top is browning too quickly, cover the sheet pan with aluminum foil during the baking process.

Variations:

Loaded Potato Extravaganza: Add crumbled bacon, diced green onions, and a dollop of sour cream to each serving for a loaded potato twist.

Garlic Parmesan Elegance: Incorporate roasted garlic into the cheesy sauce and sprinkle extra Parmesan on top for a garlic lover’s delight.

Herb-Infused Delight: Experiment with different herbs like thyme, rosemary, or dill to infuse the dish with aromatic freshness.

Keto and Low-Carb Versions:

Keto Sheet Pan Scalloped Potatoes:

  • Replace russet potatoes with cauliflower florets or turnip slices for a low-carb alternative.
  • Use almond flour instead of all-purpose flour in the cheesy sauce for keto-friendly thickening.
  • Opt for heavy cream and whole milk to maintain richness while keeping carbs in check.

Low-Carb Creamy Bliss:

  • Swap out russet potatoes for daikon radish slices for a lower-carb option.
  • Use a low-carb thickener like xanthan gum in the cheesy sauce.
  • Experiment with a blend of low-carb cheeses, such as mozzarella and Gouda, for the sauce.
