½ cup grated Parmesan cheese
2 tablespoons chopped fresh parsley

For the Cream Sauce

3 tablespoons unsalted butter
3 cloves garlic, minced
3 tablespoons all-purpose flour
2 cups whole milk
1 cup heavy cream
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon onion powder
1 teaspoon garlic powder
1 teaspoon dried thyme
½ teaspoon paprika
Pinch of nutmeg (optional)

Chopped green onions
Fresh chives
Extra Parmesan cheese
Fresh thyme leaves

Kitchen Equipment

9×13-inch baking dish
Large saucepan
Whisk
Sharp knife or mandoline slicer
Mixing spoon
Aluminum foil

Step-by-Step Directions

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C).

Grease a 9×13-inch baking dish with the softened butter.

Step 2: Slice the Potatoes

Peel the potatoes if desired.

Slice them into ⅛-inch thick rounds using a sharp knife or mandoline for even cooking.

Place the sliced potatoes in cold water while preparing the sauce to prevent browning.

Drain and pat dry before assembling.

Step 3: Make the Cream Sauce

In a large saucepan over medium heat, melt the butter.

Add the minced garlic and cook for about 1 minute until fragrant.

Whisk in the flour and cook for another minute.

Gradually pour in the milk while whisking continuously.

Add the heavy cream and continue whisking until smooth.

Season with:

Salt
Black pepper
Onion powder
Garlic powder
Dried thyme
Paprika
Nutmeg (if using)

Cook for 4–5 minutes until the sauce begins to thicken.

Remove from the heat.

Step 4: Assemble the Casserole

Arrange one-third of the sliced potatoes in an even layer in the baking dish.

Pour one-third of the cream sauce over the potatoes.

Sprinkle with one-third of the cheddar and mozzarella cheeses.

Repeat the layers two more times.

Finish with the remaining Parmesan cheese on top.

Step 5: Bake Covered

Cover the baking dish tightly with aluminum foil.

Bake for 50 minutes.

Step 6: Bake Uncovered

Remove the foil.

Continue baking for 25–30 minutes, or until the potatoes are tender when pierced with a knife and the cheese is golden brown and bubbling.

If needed, broil for 2–3 minutes for extra browning.

Step 7: Rest Before Serving

Remove the casserole from the oven.

Allow it to rest for 10–15 minutes before serving.

This helps the sauce thicken and makes slicing easier.

Step 8: Garnish

Sprinkle with chopped parsley, chives, bacon, or green onions if desired.

Serve warm.

Storage Tips

Refrigerator

Store leftovers in an airtight container for up to 4 days.

Freezer

Freeze the fully baked casserole for up to 2 months.

Thaw overnight in the refrigerator before reheating.

Reheating

Cover with foil and bake at 350°F (175°C) for 20–25 minutes, or microwave individual portions until heated through.

Helpful Tips

Slice the potatoes evenly so they cook at the same rate.
Yukon Gold potatoes create a naturally creamy texture, while russet potatoes produce a fluffier casserole.
Freshly grate the cheese for the smoothest melting.
Let the casserole rest before serving to help the sauce set.
If the top browns too quickly, loosely cover it with foil during the final baking time.

Recipe Variations

Herb Lover’s Version

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. Assemble the casserole up to 24 hours in advance, cover, and refrigerate. Bake when ready to serve, adding 10–15 minutes to the baking time if it’s coming straight from the refrigerator.

What’s the best potato to use?

Yukon Gold potatoes offer a buttery flavor and creamy texture, while russet potatoes create a softer, fluffier casserole.

Can I use half-and-half instead of heavy cream?

Yes. The sauce will be slightly lighter but still creamy.

Why are my potatoes still firm?

The slices may be too thick, or the casserole may need additional baking time. Test with a knife before removing it from the oven.

Can I add vegetables?

Absolutely. Sautéed mushrooms, spinach, broccoli, or caramelized onions make excellent additions.
