This easy Scalloped Potatoes recipe is one of our favorite side dishes! Thinly sliced potatoes covered in a cheesy sauce makes this classic casserole a perfect side.
3 tablespoons butter
1 cup onion, diced
1 tablespoon chopped garlic
1/4 cup flour
1 cup chicken broth
2 cups whole milk
4 ounces cream cheese
2 teaspoon kosher salt
Fresh black pepper to taste
1/2 teaspoon paprika
2 teaspoons fresh thyme leaves, chopped
4 pounds Yukon Gold potatoes, sliced 1/8″ thick
1/2 cup parmesan cheese, divided
2 cups sharp cheddar cheese, divided (yellow or white)
Preheat the oven to 400 degrees.
Melt the butter in a large skillet over medium heat. Ad the onion and cook for 5 minutes, stirring until softened. Add the garlic and cook for 1 minute longer.
Sprinkle the flour over the onions and garlic and stir until all the flour is combined. Cook the flour out for 1 minute, then slowly pour in the chicken stock, whisking as you pour.
Once the flour is combined with the stock, pour in the milk and add the cream cheese, salt, pepper, paprika, thyme and 1/4 cup of the parmesan cheese. Whisk the sauce together to blend the cream cheese and bring to a simmer for 5 minutes. Remove the skillet from the heat.
Spray a 9″ x 13″ casserole dish with cooking spray. Add a layer of the sliced potatoes (about half) into an even layer. Season the sliced potatoes with more salt and pepper, then add half of the sauce and spread out to cover the potatoes. Add 1 cup of the cheddar cheese on top of the sauce in an even layer.
Add the rest of the potatoes, season with more salt and pepper, then the rest of the sauce.
Cover the dish tightly with aluminum foil and bake for 35 minutes. Remove the casserole dish from the oven and top the potatoes with the remaining cup of cheddar cheese and the remaining 1/4 cup of parmesan cheese.
Place the potatoes back into the oven, uncovered for another 25 minutes. After you remove the scalloped potatoes from the oven, check to make sure they are fork tender. If some are still firm, cover the baking dish again and place back into the oven for another 10 minutes.
Garnish with additional fresh thyme and more parmesan cheese if desired.
