How to Make Italian Vegetable Frittata with Zucchini, Bell Peppers, and Mozzarella Recipe

Step 1: Preheat and Prepare

Start by preheating your oven to 400 degrees Fahrenheit. This ensures the frittata will bake evenly and achieve that perfect golden top. Meanwhile, gather your ingredients to streamline the cooking process.

Step 2: Sauté the Vegetables

Heat a cast iron or other oven-safe pan over medium heat and swirl in the grapeseed oil to coat the surface. Slice the zucchini in half lengthwise and then thinly slice. Similarly, thinly slice bell peppers and shallots, and mince the garlic. Add these to the heated pan and season with salt, pepper, and oregano. Sauté for about 7 minutes, allowing the vegetables to soften and their flavors to meld beautifully.

Step 3: Wilt the Spinach

Next, add the baby spinach to the pan and stir it in gently. Cook until it wilts, roughly 3 minutes. This step adds a lovely leafy green texture and subtle earthiness, balancing the sweetness of the bell peppers.

Step 4: Add the Mozzarella

Slice the mozzarella into small chunks and scatter them across the vegetables in the pan. The fresh cheese will slowly melt, creating gooey, irresistible pockets throughout your frittata.

Step 5: Whisk the Eggs and Pour

In a medium-sized mixing bowl, crack the eggs and combine them with the heavy cream and grated Pecorino Romano cheese. Whisk vigorously until the mixture is smooth and pale yellow. Pour this egg mixture evenly over the veggies and cheese in the pan, making sure everything is nicely coated.

Step 6: Cook and Bake

Allow the frittata to cook undisturbed over medium heat until the edges start to set, about 5 minutes. Then transfer the pan to the preheated oven, placing it on the center rack. Bake for 15 minutes, or until the frittata is puffed and golden on top, and a knife inserted in the center comes out clean.

Step 7: Garnish and Serve

Remove the frittata from the oven and let it rest for a minute. Garnish generously with freshly chopped parsley and an extra sprinkle of Pecorino Romano to add brightness and an appealing finish. Now it’s ready to enjoy!

Garnishes

Freshly chopped parsley is a classic finish that adds vibrant green color and a subtle fresh flavor. For a little extra zing, consider a light drizzle of extra virgin olive oil or a pinch of red pepper flakes to wake up the palate.

Side Dishes

This Italian vegetable frittata pairs wonderfully with a crisp garden salad, lightly dressed with lemon vinaigrette, or some crusty bread to soak up any lingering cheese and egg. A side of fresh-roasted potatoes or a bowl of tomato soup can also complement the meal beautifully.

Creative Ways to Present

For a fun brunch twist, cut the frittata into bite-sized squares and serve on a platter with toothpicks alongside a variety of dips such as basil pesto, garlic aioli, or sun-dried tomato spread. You can also serve slices on top of toasted baguette rounds for a savory appetizer option at gatherings.

Make Ahead and Storage

Storing Leftovers

Leftover frittata keeps well in an airtight container in the refrigerator for up to 3 days. It’s a fantastic make-ahead meal for quick breakfasts or easy lunches throughout the week. Just reheat and enjoy the comforting flavors all over again.

Freezing

This frittata freezes nicely if you want to stock your freezer with ready meals. Wrap individual slices tightly in plastic wrap and place in a freezer-safe bag or container. It will keep fresh for up to 2 months when properly stored.

Reheating

To reheat, gently warm slices in a skillet over medium-low heat or pop them in the microwave until heated through. Avoid overcooking to preserve the creamy texture of the eggs and the gooey mozzarella.
