Cheesy Garlic Scalloped Potatoes

Cheesy Garlic Scalloped Potatoes

Cheesy garlic scalloped potatoes are the ultimate comfort food side dish. Thinly sliced potatoes are layered with a rich, creamy garlic sauce and an abundance of melted cheese, then baked until golden, bubbly, and fork-tender. Every spoonful delivers velvety potatoes, savory garlic, and stretches of gooey cheese. This dish steals the show at holiday dinners, Sunday suppers, and potlucks. It is the perfect companion to ham, roast beef, chicken, or prime rib.

Why These Scalloped Potatoes Work

The secret to perfect scalloped potatoes is cooking the sauce before baking. Heating the cream, garlic, and cheese creates a stable emulsion that will not separate or become greasy in the oven. Thin, uniform slices are essential. A mandoline produces slices that cook evenly and stack neatly. Yukon Gold potatoes are the best choice. They have a naturally buttery flavor and creamy texture, and they hold their shape without becoming mushy. Using a blend of sharp cheddar and Parmesan provides both excellent meltability and deep, savory flavor. Do not rinse the sliced potatoes. The natural starch helps thicken the sauce as the dish bakes.

Ingredients

• 3 pounds Yukon Gold potatoes

• 2 cups heavy cream

• 4 cloves garlic, minced

• 2 cups shredded sharp cheddar cheese, divided

• 1/2 cup grated Parmesan cheese

• 2 tablespoons unsalted butter

• 1 teaspoon salt

• 1/2 teaspoon black pepper

• 1/2 teaspoon dried thyme or rosemary (optional)

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Grease a 9×13-inch baking dish with butter or cooking spray.

Step 2: Slice the Potatoes

Wash and peel the potatoes if desired. Using a mandoline or a sharp knife, slice the potatoes into 1/8-inch thick rounds. Uniform thickness is critical for even cooking.

Step 3: Make the Garlic Cream Sauce

In a medium saucepan over medium heat, combine the heavy cream, minced garlic, salt, pepper, and dried thyme if using. Bring to a gentle simmer, stirring occasionally. Remove from heat. Stir in 1 1/2 cups of the shredded cheddar cheese and all of the Parmesan cheese until melted and smooth.

Step 4: Layer the Potatoes

Arrange half of the sliced potatoes in the prepared baking dish, overlapping slightly. Pour half of the cheese sauce evenly over the potatoes. Repeat with the remaining potatoes and the remaining sauce. Dot the top with small pieces of butter.

Step 5: Top with Cheese

Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top of the casserole.

Step 6: Bake

Cover the baking dish with aluminum foil. Bake for 30 minutes. Remove the foil and bake for another 25 to 30 minutes until the potatoes are fork-tender, the sauce is bubbly, and the top is golden brown. If the top needs more color, broil for the final two to three minutes.

Step 7: Rest and Serve

Let the cheesy garlic scalloped potatoes rest for ten to fifteen minutes before serving. Resting allows the sauce to thicken slightly and prevents it from running all over the plate.

Variations and Tips

Add cooked, crumbled bacon between the layers. Substitute Gruyère or fontina for some of the cheddar. Add thinly sliced onions or leeks between the layers. Use sweet potatoes instead of Yukon Golds. Add a pinch of nutmeg to the sauce for warmth. Store leftovers in the refrigerator for up to four days. Reheat covered in a 350-degree oven or in individual portions in the microwave. This dish does not freeze well, as the sauce can separate. For a make-ahead version, assemble the casserole completely, cover, and refrigerate for up to two days. Add ten to fifteen minutes to the baking time. Use a mandoline carefully. The blade is extremely sharp. Always use the guard. For a dairy-free version, use full-fat coconut milk and dairy-free cheese shreds. These cheesy garlic scalloped potatoes are decadent, creamy, and impossible to resist. The crispy, golden top gives way to tender, buttery potatoes bathed in a rich, cheesy garlic sauce. They are the side dish that becomes the main attraction. Make extra, because everyone goes back for seconds. Serve alongside your favorite protein, and prepare for silence at the table as everyone enjoys every single bite.
