Put raw sliced onions in casserole. 3 ingredients later: Comfort food you didn’t know you needed

Ingredients

4 large onions, thinly sliced
2 cups shredded Gruyère cheese
1 cup beef broth
1 cup breadcrumbs

Directions

Preheat your oven to 375°F (190°C).

In a large skillet over medium heat, cook the sliced onions until they are soft and caramelized, about 20-25 minutes. Stir occasionally to prevent burning.

Transfer the caramelized onions to a baking dish and spread them evenly.

Pour the beef broth over the onions, ensuring they are well-coated.

Sprinkle the shredded Gruyère cheese evenly over the onions.

Top with breadcrumbs, spreading them out to cover the cheese layer.

Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and the breadcrumbs are golden brown.

Allow to cool slightly before serving.

Variations & Tips

For a vegetarian version, substitute the beef broth with vegetable broth. You can also add a layer of cooked mushrooms for an earthy flavor. If Gruyère is not available, Swiss cheese or mozzarella can be used as alternatives. For a bit of a kick, consider adding a pinch of red pepper flakes to the onions while they caramelize. To enhance the dish’s texture, mix some chopped nuts, like walnuts or pecans, into the breadcrumbs before topping the bake.
