Ingredients

4 medium potatoes, peeled and thinly sliced

2 cups shredded cheddar cheese

1 cup mozzarella cheese

1 cup milk

1/2 cup heavy cream

2 tablespoons butter

2 eggs

1 small onion, finely chopped

2 cloves garlic, minced

1/2 teaspoon black pepper

1 teaspoon salt, or to taste

1 teaspoon paprika

1 teaspoon dried parsley

1/2 teaspoon Italian seasoning

2 tablespoons chopped fresh parsley

Cooking oil or butter for greasing the baking dish

Step 1: Prepare the Potatoes

Start by washing and peeling the potatoes. Slice them into thin, even pieces so they cook evenly in the oven.

Place the sliced potatoes in a large bowl of cold water for approximately 10 minutes. This helps remove excess starch. Drain the water and pat the potatoes dry with a clean kitchen towel.

For a softer casserole, you can boil the potato slices for about 5 minutes before assembling the dish. Do not cook them completely because they will finish cooking in the oven.

Step 2: Prepare the Creamy Mixture

Take a large mixing bowl and add the milk, heavy cream, and eggs. Whisk everything together until smooth.

Add salt, black pepper, paprika, Italian seasoning, and minced garlic. Mix thoroughly to distribute the seasonings.

Add the chopped onion and fresh parsley. Stir again until all the ingredients are combined.

This creamy mixture gives the potatoes a rich flavor and helps create a soft, delicious texture.

Step 3: Prepare the Cheese

Take another bowl and combine the shredded cheddar cheese and mozzarella cheese.

Keep approximately half a cup of cheese aside for the final topping.

Cheddar provides a rich, slightly sharp flavor, while mozzarella creates a stretchy and delicious melted cheese layer.

You can also use Monterey Jack or another melting cheese if desired.

Step 4: Assemble the Casserole

Preheat your oven to 180°C (350°F).

Grease a rectangular glass baking dish with butter or cooking oil.

Arrange a layer of sliced potatoes across the bottom of the dish. Sprinkle some shredded cheese over the potatoes.

Add another layer of potatoes followed by another portion of cheese.

Continue layering until all the potatoes and cheese have been used.

Pour the prepared creamy mixture evenly over the entire casserole. Gently shake the dish so the liquid reaches between the potato slices.

Finally, sprinkle the remaining cheese over the top.

Step 5: Bake Until Golden

Place the baking dish in the preheated oven.

Bake for approximately 35–45 minutes, depending on the thickness of your potato slices and the depth of your baking dish.

The potatoes should become tender, and the creamy mixture should be set.

If the cheese begins browning too quickly before the potatoes are cooked, loosely cover the dish with aluminum foil.

Remove the foil during the final 10 minutes to allow the cheese topping to become golden brown and slightly crispy.

Check the potatoes with a fork. If they are soft and easily pierced, the casserole is ready.

Step 6: Rest Before Serving

Remove the casserole from the oven and allow it to rest for 10–15 minutes.

This resting time helps the creamy filling settle and makes the casserole easier to cut into neat portions.

Sprinkle fresh chopped parsley over the top for extra color and freshness.

Cut into squares and serve warm while the cheese is still deliciously melted.

Tips for the Best Potato Casserole

Slice the potatoes evenly so they cook at the same rate.

Use freshly shredded cheese for better melting.

Avoid adding too much milk because the casserole may become watery.

For extra flavor, add cooked bacon, mushrooms, bell peppers, or broccoli.

If you enjoy spicy food, add a little chili powder or red pepper flakes.

Always check that the potatoes are completely tender before removing the casserole from the oven.

What to Serve With Cheesy Potato Casserole

This comforting casserole tastes wonderful with grilled chicken, roasted beef, baked fish, or fried chicken.

You can also serve it with a fresh green salad, steamed broccoli, roasted carrots, or garlic bread.

For a complete family meal, pair it with a simple cucumber and tomato salad.

Storage and Reheating

Allow leftover casserole to cool before transferring it into an airtight container.

Refrigerate for up to 3–4 days.

To reheat, place individual portions in the microwave until thoroughly heated. You can also reheat the entire casserole in an oven at 170°C (340°F), covering it loosely with foil to prevent the cheese from becoming too dark.

For longer storage, freeze portions in freezer-safe containers for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating.
