Ingredients
  

6 large eggs

1 cup of milk

2 tablespoons olive oil

1 large onion, thinly sliced

8 ounces cremini or button mushrooms, sliced

1 teaspoon fresh thyme or 1/2 teaspoon dried thyme

Salt and pepper, to taste

1/2 cup grated mozzarella cheese (optional)

Fresh parsley, chopped (for garnish)

Instructions
 

Preheat the Oven: Preheat your oven to 375°F (190°C).

    Caramelize the Onions: In a large oven-safe skillet, heat the olive oil over medium heat. Add the sliced onions, and cook slowly, stirring occasionally, for about 15 minutes or until the onions become golden brown and caramelized. If they start to stick, add a splash of water or more olive oil.

      Add the Mushrooms: Once the onions are caramelized, add the sliced mushrooms to the skillet. Sauté for 5-7 minutes, or until the mushrooms are soft and any released liquid has evaporated.

        Mix Eggs and Milk: In a large bowl, whisk together the eggs, milk, thyme, salt, and pepper until well combined.

          Combine: Pour the egg mixture over the caramelized onions and mushrooms in the skillet. Gently stir to distribute the vegetables evenly. If using, sprinkle the mozzarella cheese on top.

            Cook on the Stovetop: Cook on the stovetop over medium heat for about 5 minutes, allowing the edges to set while the middle is still slightly runny.

              Bake: Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the frittata is puffed and golden brown, and a toothpick inserted in the center comes out clean.

                Serve: Remove from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley, slice, and serve warm or at room temperature.
