Why This Recipe Works

This Cheesy Scalloped Potato Casserole stands out because of its perfect balance of creamy and cheesy textures. The russet potatoes hold their shape while becoming tender, creating layers that soak up the savory cream sauce infused with garlic and onion.

Whether you’re a seasoned cook or a beginner, the step-by-step process is straightforward, making it an accessible dish that yields restaurant-quality results at home.

What You’ll Gather

Tools of the Trade

• Sharp knife and cutting board – for slicing potatoes and chopping onion
• Mandoline slicer (optional) – to ensure uniform, thin potato slices

Method: Cheesy Scalloped Potato Casserole

Step 1: Prepare the Potatoes and Aromatics

Start by washing and peeling your russet potatoes. Using a sharp knife or mandoline slicer, thinly slice the potatoes about 1/8 inch thick. This ensures they cook evenly and absorb the creamy sauce. Finely chop the onion and mince the garlic cloves.

Step 2: Sauté Onions and Garlic

In a large skillet, melt the butter over medium heat. Add the chopped onion and sauté until softened and translucent, about 5 minutes. Stir in the minced garlic and cook for another 1-2 minutes, until fragrant but not browned.

Step 3: Make the Creamy Sauce

Pour the heavy cream and chicken broth into the skillet with the onions and garlic. Stir in salt, black pepper, paprika, and nutmeg. Bring the mixture to a gentle simmer, stirring occasionally. Remove from heat once it’s warmed through and the flavors have melded.

Step 4: Layer the Casserole

Preheat your oven to 350°F (175°C). Lightly grease your 9×13 inch baking dish. Arrange a layer of sliced potatoes on the bottom, slightly overlapping. Sprinkle a portion of the shredded cheddar and mozzarella over the potatoes. Repeat layering with the remaining potatoes and cheeses, finishing with a cheese layer on top.

Step 5: Pour the Sauce and Bake

Slowly pour the creamy sauce evenly over the layered potatoes and cheese, allowing it to seep through the layers. Cover the dish tightly with aluminum foil and bake in the preheated oven for 60 minutes.

Step 6: Brown the Top

After 60 minutes, remove the foil and continue baking uncovered for an additional 20-25 minutes. This will let the top cheese layer bubble and brown to a perfect golden finish.

Step 7: Garnish and Serve

Once out of the oven, let the casserole rest for 10 minutes to set. Sprinkle the chopped fresh parsley over the top for a burst of color and fresh flavor. Serve warm and enjoy!

Better-for-You Options

• Swap heavy cream for half-and-half or whole milk mixed with a tablespoon of cornstarch for a lighter sauce.
• Use low-sodium chicken broth to reduce salt content.
• Incorporate cauliflower slices to add extra veggies and reduce carbs.
• Choose reduced-fat cheeses to cut down on saturated fat.
• Try fresh herb blends like thyme or rosemary for added natural flavor without extra salt.

Slip-Ups to Skip

• Don’t slice potatoes too thick; thick slices take longer to cook and won’t absorb sauce well.
• Avoid skipping the resting step after baking—it helps the casserole set for easier serving.
• Don’t rush the baking time; undercooked potatoes can be crunchy and unpleasant.
• Make sure to cover the casserole initially to prevent the top from burning before the potatoes cook through.

Prep Ahead & Store

This Cheesy Scalloped Potato Casserole is perfect for prepping ahead. You can assemble the entire casserole up to a day in advance, cover tightly, and refrigerate. When ready, bake as directed, adding extra baking time if baking from cold.

Leftovers store well in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave until warmed through. To freeze, wrap tightly with foil and plastic wrap; thaw overnight before reheating.

FAQ

Can I use a different type of potato for this casserole?

Russet potatoes are ideal for their starchy texture, which creates creamy layers. However, Yukon Gold potatoes also work well if you prefer a slightly waxier texture. Avoid waxy potatoes like red potatoes as they don’t soften as well.

Is it possible to make this recipe vegetarian?

Absolutely! Simply substitute the chicken broth with vegetable broth to keep the dish fully vegetarian without compromising flavor.

How do I prevent the top from burning before the potatoes are cooked?

Covering the casserole with foil during the majority of the baking time traps moisture and prevents the cheese from burning. Remove the foil during the last 20-25 minutes to brown the cheese nicely.

Can I add other ingredients like bacon or herbs?

You can add cooked bacon or fresh herbs like thyme or rosemary for additional flavor layers. Just keep in mind this will alter the classic profile of the dish.
