Crustless Caramelized Onions and Cheese

Ingredients

• 1 tablespoon butter
• 2 teaspoons olive oil
• 1 small onion, diced
• 3/4 cup heavy whipping cream
• 3 eggs
• Salt and ground black pepper to taste
• 3/4 cup shredded mozzarella cheese
• 1/4 cup grated Parmesan cheese

Directions

Preheat oven to 350 degrees F (175 degrees C). Grease an 8×8-inch baking dish.

Heat butter and olive oil in a skillet over medium-high heat; cook and stir onion in the heated butter-olive oil until onions soften, about 10 minutes. Transfer onion to a plate to cool.

Whisk cream, eggs, salt, and black pepper in a bowl; stir in mozzarella cheese, Parmesan cheese, and onion. Pour mixture into the prepared baking dish.

Bake in the preheated oven until eggs are set and a knife inserted in the center comes out clean, about 35 minutes.
