Ingredients
  

6 large eggs

1 cup milk (whole or 2%)

1 large onion, thinly sliced

1 cup mushrooms (cremini or button), sliced

2 tablespoons olive oil

2 tablespoons unsalted butter

1 teaspoon fresh thyme leaves

1 cup shredded cheese (cheddar or Gruyère)

Salt and pepper to taste

Fresh parsley, chopped (for garnish)

Instructions
 

Preheat the oven: Begin by preheating your oven to 375°F (190°C) to prepare it for baking the frittata.

    Caramelize the onions: In a large oven-safe skillet, combine the olive oil and butter over medium heat. Once the butter has melted, add the sliced onions. Cook gently, stirring occasionally, until the onions turn a beautiful golden brown and become caramelized, approximately 15-20 minutes. Sprinkle a pinch of salt into the onions to encourage them to soften and enhance their sweetness.

      Add mushrooms: Once the onions are caramelized, introduce the sliced mushrooms to the skillet. Continue cooking for an additional 5-7 minutes, stirring occasionally, until the mushrooms become tender and nicely browned. Add in the fresh thyme and season with freshly ground black pepper to elevate the flavors.

        Prepare the egg mixture: In a separate mixing bowl, crack the eggs and whisk them together with the milk until fully combined and slightly frothy. Season this mixture with salt and pepper to taste, making sure it's well-balanced.

          Combine ingredients: Carefully pour the egg mixture over the caramelized onion and mushroom mixture in the skillet. Gently stir with a spatula to evenly distribute the onions and mushrooms throughout the frittata base. Top with the shredded cheese, allowing it to melt and create a delicious layer of flavor.

            Cook on stovetop: Allow the skillet to sit on the stovetop for about 3-5 minutes. This initial cooking helps the edges of the frittata begin to set slightly.

              Bake the frittata: Carefully transfer the skillet to the preheated oven. Bake for 15-20 minutes or until the frittata is puffed and a toothpick inserted into the center comes out clean, indicating it’s fully set.

                Cool and serve: Once baked, remove the frittata from the oven and let it cool for a few minutes. Before slicing into wedges, garnish with freshly chopped parsley to add a touch of color and freshness. Serve warm and enjoy this delightful dish!
