Ingredients You’ll Need

Selecting the right ingredients is key to making Crispy French Onion Scalloped Potato Casserole.

Main Protein

You won’t need protein for this dish, so focus on the starchy goodness of potatoes.

Starch/Pasta

Yukon Gold potatoes
These are the ideal choice for their creamy texture and buttery flavor.
To prepare, simply wash and thinly slice them.
If you’re looking for an alternative, russet potatoes will work but may be less creamy.
Make sure to slice uniformly for even cooking.

Seasoning/Spice Blend

Salt and black pepper
These basic seasonings enhance the flavor.
You’ll need to add them during layers and cooking.
If you’re looking for an alternative, consider using garlic powder for extra depth.
Ensure you taste as you go to adjust for preference.

Liquids/Dairy

Heavy cream
This provides the rich, creamy base for your casserole.
Pour it directly over the layered ingredients.
If you’re looking for an alternative, half-and-half can reduce calories, but won’t be as rich.
Use fresh cream for the best flavor.

Aromatics & Vegetables

Yellow onions
Sweet and delicious when caramelized, they are essential for flavor.
Slice and sauté until golden before layering.
If you’re looking for an alternative, shallots could offer a milder taste.
Keep an eye on them to prevent burning.

Optional Finishing Ingredients

Gruyère and Parmesan cheese
These cheeses create a crispy, golden topping.
Grate and mix them before sprinkling on top.
If you’re looking for an alternative, cheddar can be a good substitute for a sharper flavor.
Use fresh cheeses for the best result.

Step-by-Step Instructions

This one-pan dish is not only easy but also allows flavors to meld beautifully.

Step 1: Sauté the Onions

Begin by melting 4 tablespoons of unsalted butter in a skillet over medium heat.
Add the sliced yellow onions and cook them until they caramelize, about 15-20 minutes.
Stir occasionally and watch for a deep golden color; this deep flavor is what you’re aiming for.

Step 2: Prepare the Potatoes

While the onions are cooking, thinly slice the Yukon Gold potatoes using a mandoline or a sharp knife.
Aim for slices about ⅛-inch thick for best results.
This ensures they cook evenly within the casserole.

Step 3: Mix the Cream

In a separate bowl, combine 2 cups of heavy cream with minced garlic, thyme, salt, and black pepper.
Whisk it together until well blended.
The aromatic garlic will enhance the flavor as it bakes.

Step 4: Layer the Ingredients

In a greased casserole dish, layer half of the potato slices, followed by half of the sautéed onions.
Pour half of the cream mixture over these layers.
Repeat with the remaining potatoes, onions, and cream. This builds flavor and richness.

Step 5: Add the Cheese

Top the final layer with 1.5 cups of shredded Gruyère cheese and 1 cup of grated Parmesan cheese.
This will create that beautiful, bubbly crust.
Sprinkle evenly and make sure to cover the top well.

Step 6: Bake the Casserole

Cover the dish with foil and bake in a preheated oven at 375°F (190°C) for 30 minutes.
Afterward, remove the foil and bake for an additional 15-20 minutes until the top is golden and the potatoes are tender.
You’ll know it’s done when a fork easily pierces the potatoes.

Step 7: Let It Rest

Once out of the oven, allow the casserole to rest for about 10 minutes before serving.
This helps it set a bit and makes serving easier.
The aromas will drive everyone wild!

How to Serve

1. Garnish with fresh herbs for a pop of color.
2. Pair with roasted meats or a crisp salad.
3. Serve in generous portions; guests will want more.
4. A light white wine or sparkling water balances the rich flavors.

This casserole is sure to impress at every meal!
