Ingredients

onions
butter
olive oil
salt
pepper
garlic
thyme
heavy cream
milk
cheese (cheddar, Gruyère, or a mix)
flour
Parmesan cheese

Directions

Preheat the Oven: Set your oven to 375°F (190°C).
Caramelize the Onions: In a skillet, heat olive oil and butter over medium-low heat. Add thinly sliced onions and cook slowly, stirring occasionally, until they turn golden brown and fragrant (about 20-25 minutes). Set aside.
Prepare the Cheese Sauce: In a saucepan, melt butter and whisk in flour, cooking for a minute to remove the raw taste. Gradually add milk and heavy cream, whisking continuously until smooth. Stir in garlic, thyme, salt, and pepper. Once the mixture thickens, add shredded cheese and stir until melted.
Assemble the Layers: In a greased baking dish, layer thinly sliced potatoes, followed by a portion of the caramelized onions, and then a drizzle of the cheese sauce. Repeat the layers until all ingredients are used, finishing with a generous topping of Parmesan cheese.
Bake: Cover with foil and bake for 40 minutes. Remove the foil and continue baking for another 20 minutes or until the top is golden brown and bubbly.
Rest and Serve: Let the dish rest for 10 minutes before serving to allow the sauce to set properly.

Variations

Add Bacon: Crispy bacon bits add a smoky, savory punch to the dish.
Use Different Cheeses: Swap out cheddar for smoked gouda, mozzarella, or Swiss cheese for a unique twist.
Make it Spicy: Add red pepper flakes or diced jalapeños for a kick of heat.
Dairy-Free Option: Use plant-based milk, vegan cheese, and coconut cream for a dairy-free version.
Herb Infusion: Experiment with rosemary or sage for an earthy, aromatic touch.

FAQs

How do I slice the potatoes evenly?

Use a mandoline slicer for uniform thickness, which ensures even cooking.

Can I make this dish ahead of time?

Yes! Assemble the dish a day in advance and refrigerate. Bake when ready to serve.

What type of potatoes work best?

Yukon Gold or Russet potatoes are ideal due to their creamy texture.

How do I prevent the sauce from curdling?

Avoid using high heat and ensure the milk and cream are warmed before adding them to the sauce.

Can I use pre-shredded cheese?

It’s best to shred cheese from a block since pre-shredded varieties contain anti-caking agents that affect melting.

How do I make it gluten-free?

Use a gluten-free flour blend or cornstarch as a thickener for the cheese sauce.

Can I add protein?

Yes! Cooked chicken, ham, or sausage can be layered in for a heartier dish.

Why are my potatoes not fully cooked?

Ensure they are sliced thinly and bake long enough. Covering with foil helps steam them.

How do I get a crispier top?

Broil for 2-3 minutes at the end of baking for a golden, crispy finish.

What can I serve this with?

This dish pairs well with roasted meats, grilled vegetables, or a fresh green salad.
