- 2 tablespoons olive oil or butter
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Fresh parsley for garnish (optional)
Timing
Preparing Holiday Frittata with Mushrooms and Gruyère takes about 15 minutes for prep and 25-30 minutes for cooking, totaling approximately 40-45 minutes.
Step-by-Step Instructions
Step 1: Preheat Oven
- Preheat Oven: Preheat your oven to 375°F (190°C).
Step 2: Sauté the Vegetables
- Heat Oil: In a large oven-safe skillet (preferably cast iron), heat the olive oil or butter over medium heat.
- Cook Onions and Mushrooms: Add the diced onion and sliced mushrooms to the skillet. Sauté for about 5-7 minutes, or until the onions are translucent and the mushrooms are tender. Season with salt, pepper, and thyme.
Step 3: Prepare the Egg Mixture
- Whisk Eggs: In a large bowl, whisk together the eggs and milk (or cream) until well combined. Stir in half of the Gruyère cheese.
Step 4: Combine and Cook

- Transfer to Oven: Place the skillet in the preheated oven and bake for 15-20 minutes, or until the frittata is set in the center and lightly golden on top. You can check for doneness by inserting a knife in the center; it should come out clean.
Step 6: Cool and Serve

- Garnish: If desired, garnish with fresh parsley before slicing.
- Serve: Cut into wedges and serve warm or at room temperature.
