Ingredients You’ll Need

Potatoes & Base

2 pounds russet potatoes, peeled and shredded
- Use frozen shredded hash browns (about 32 ounces) if you want a shortcut; thaw and pat dry.
1 small yellow onion, finely diced
2 cloves garlic, minced
3 tablespoons unsalted butter, melted
1 tablespoon olive oil

Creamy Sauce

1 ½ cups sour cream
- Use full-fat for best texture; light sour cream works but tastes less rich.
1 cup whole milk or half-and-half
1 can (10.5 ounces) condensed cream of chicken soup
- Use cream of mushroom soup for a vegetarian version.
1 teaspoon kosher salt
½ teaspoon black pepper
½ teaspoon smoked paprika
½ teaspoon onion powder
½ teaspoon garlic powder

Cheese & Mix-ins

2 cups shredded sharp cheddar cheese, divided
- Pre-shredded cheese saves time; block cheese melts smoother.
1 cup shredded Monterey Jack or mozzarella
½ cup grated Parmesan cheese
½ cup cooked bacon bits or crumbled bacon (optional)
¼ cup chopped green onions or chives

Crunchy Topping

1 ½ cups crushed cornflakes or buttery crackers
3 tablespoons melted butter
¼ teaspoon smoked paprika
Pinch of salt

Equipment

9×13 inch baking dish (ceramic or glass)
Large mixing bowl
Whisk
Box grater or food processor with shredding blade
Foil
Nonstick spray or extra butter for greasing the dish

Tips & Tricks

Squeeze excess moisture from shredded potatoes with a clean kitchen towel so the casserole bakes creamy, not watery.
Use sharp cheddar for bold flavor and mix in a milder cheese like Monterey Jack for extra meltiness.
Season the potato mixture generously; bland potatoes need more salt and spices than you think.
Grease the baking dish well so the cheesy edges release easily and you keep those tasty browned bits.
Cover the casserole with foil for the first part of baking so the center cooks through, then uncover to crisp the top.
Add cooked bacon, diced ham, or sautéed mushrooms to turn this into a hearty main dish.
Prep the casserole a day ahead, cover tightly, and refrigerate; add 10 to 15 minutes to the baking time if it goes into the oven cold.
Let the casserole rest 10 minutes after baking so it sets and slices neatly instead of sliding all over the plate.

How to Make Tasty Cheesy Potato Casserole Recipe

Step 1: Prep the Potatoes and Pan

Preheat your oven to 375°F and grease a 9×13 inch baking dish with butter or nonstick spray. Peel and shred the russet potatoes on the large holes of a box grater. Place the shredded potatoes in a clean kitchen towel, squeeze out as much liquid as you can, and transfer them to a large mixing bowl.

Add the diced onion, minced garlic, melted butter, and olive oil to the potatoes. Toss everything together so the potatoes get a light, even coating of fat and aromatics.

Step 2: Mix the Creamy Sauce

In a separate bowl, whisk together the sour cream, milk or half-and-half, and condensed cream of chicken soup until smooth. Add the salt, pepper, smoked paprika, onion powder, and garlic powder. Whisk again so the spices spread evenly through the sauce.

Pour this mixture over the shredded potatoes and onions. Stir until every strand of potato looks coated and creamy.

Step 3: Add the Cheese and Mix-ins

Stir in 1 ½ cups of the shredded sharp cheddar, all of the Monterey Jack or mozzarella, and the Parmesan. Fold in the bacon bits and half of the chopped green onions or chives if you use them. Mix gently so you keep some texture and pockets of cheese.

Taste a small spoonful of the mixture and adjust the seasoning with a bit more salt or pepper if needed. The mixture should taste slightly more seasoned than you want the final dish, since the potatoes mellow the flavor as they bake.

Step 4: Assemble the Casserole

Spread the cheesy potato mixture evenly in the prepared baking dish. Smooth the top lightly with a spatula, but do not pack it too tightly so heat can move through the casserole. Sprinkle the remaining ½ cup of cheddar evenly over the top.

Cover the dish tightly with foil. Place it on the middle rack of the oven.

Step 5: Bake Until Tender

Bake the covered casserole for 35 minutes. The potatoes will soften and the cheese inside will melt into the sauce. Remove the foil carefully so the steam does not hit your face.

Check the center with a fork; the potatoes should feel mostly tender. If they still feel firm, return the dish to the oven for another 10 minutes before adding the topping.

Step 6: Add the Crunchy Topping

While the casserole bakes, stir together the crushed cornflakes or crackers, melted butter, smoked paprika, and a pinch of salt in a small bowl. Mix until every crumb looks lightly coated. This topping gives the casserole that perfect crunchy lid.

Sprinkle the crumb mixture evenly over the hot casserole once you remove the foil. Try to cover the surface so every scoop gets some crunch.

Step 7: Finish Baking and Rest

Return the uncovered casserole to the oven and bake for another 15 to 20 minutes. The topping should turn golden and crisp, and the edges should bubble. If the top browns too quickly, tent it loosely with foil.

Remove the casserole from the oven and let it sit on the counter for 10 minutes. Sprinkle the remaining green onions or chives over the top before serving. Slice into squares or scoop with a big spoon and serve hot.
