Step‑by‑Step Instructions for Mushroom Leek Frittata
Step 1: Prep Ingredients
Begin by gathering all the ingredients for your Mushroom Leek Frittata. Preheat your oven to 350°F (180°C) to get it ready for baking later. Clean and trim the leeks thoroughly, ensuring they’re free of grit, and slice them thinly. Prep the mushrooms by slicing them into even pieces to ensure uniform cooking.
Step 2: Sauté
In a large non-stick skillet, melt 2 tablespoons of butter over medium heat. Once melted and bubbling, add the sliced leeks and mushrooms to the pan. Sauté for about 5-7 minutes, stirring occasionally, until the leeks are soft and translucent and the mushrooms are tender and golden brown. Set aside to cool slightly.
Step 3: Mix Eggs
In a mixing bowl, crack 6 large eggs and whisk them until fully combined, creating a frothy mixture. Pour in 1/4 cup of cream (if using) and add 1 cup of Comté cheese, grated. Stir in the sautéed leeks and mushrooms along with a pinch of salt and pepper. Mix well until all ingredients are thoroughly incorporated.
Step 4: Cook on Stovetop
Return the skillet to medium heat and pour in the egg mixture. Let it cook undisturbed for about 2-3 minutes, allowing the edges to set while the center remains slightly runny. Watch for the frittata to puff up slightly around the edges, indicating it’s ready for the oven.
Step 5: Bake
Carefully transfer the skillet to your preheated oven. Bake the Mushroom Leek Frittata for approximately 15 minutes, or until the center is set and no longer jiggles when gently shaken. The top should be lightly golden at this stage.
Step 6: Broil for Finish
Remove the frittata from the oven and sprinkle a bit more grated Comté cheese on top for extra melty goodness. Switch your oven to broil and place the skillet back in for 1-2 minutes. Keep a close eye on it to achieve a beautifully golden brown top without burning.
Step 7: Serve
Once broiling is complete, take the frittata out of the oven and allow it to cool for a couple of minutes. Use a sharp knife to slice into wedges and serve warm, garnished with fresh herbs if desired. This delicious Mushroom Leek Frittata is ready to impress family and friends!
