Gather and Prep Ingredients.

Before getting started on this Caramelized Onion & Red Potato Cheesy Gratin, be sure to gather the necessary ingredients and do any prepping beforehand. You’ll need 3 tablespoons of butter, 2 onions that are thinly sliced, 4 red potatoes (peeled and halved) 1 cup shredded cheese (any variety), 1 teaspoon garlic powder, 1 teaspoon Italian seasoning, and salt & pepper to taste. Then preheat your oven to 375 degrees Fahrenheit.

Preheat the Oven and Assemble the Gratin.

Begin by preheating your oven to 375 degrees Fahrenheit, then lightly grease a 9x13 inch baking dish. Place the potatoes into the dish and top with the caramelized onions. Sprinkle garlic powder, Italian seasoning, pinch of salt & pepper, and cheese over the top. Finally, pour 3 tablespoons of melted butter over the dish and cover it with foil.

Caramelize the Onions.

To begin, heat a large skillet over medium-low heat. Add diced onions and season with a pinch of salt & pepper. Cook until the onions are browned and caramelized, stirring often. This process can take up to 20 minutes. Once finished, remove from the heat and set aside.

Arrange Red Potatoes in Gratin Mixture

Grease a 5- or 6-quart baking dish with butter and arrange the potatoes in alternating layers covered in a layer of onions. Sprinkle with shredded cheese of your choice, then pour the cream mixture over the top layer. Place in a preheated oven and bake at 375 degrees Fahrenheit for 40 minutes or until the cheese is golden brown. Serve warm and enjoy!

Combine Dairy and Layering for Baking the Gratin.

For optimal flavor and texture of the gratin add a combination of creamy dairy products like heavy cream or half-and-half, Greek yogurt, crème fraîche or sour cream. To ensure that the potatoes are cooked through, layer them with onions and cheese before pouring the combined cream mixture over the top layer then baking until cheese is golden brown.
