Essential Ingredients for Your Zucchini Frittata

To create this delightful zucchini frittata, you’ll need a selection of fresh, high-quality ingredients. The full recipe card below provides exact measurements and detailed instructions. Here’s a breakdown of what you’ll need and why each component is important:

• Eggs: The foundation of any great frittata! This recipe calls for 12 large eggs, ensuring a substantial and protein-rich dish. For the best results, aim for fresh, good-quality eggs as they contribute significantly to the frittata’s texture and flavor.
• Whole Milk: Incorporating whole milk is key to achieving that wonderfully soft and creamy frittata texture. The fat content in whole milk (or cream, for an even richer result) helps to tenderize the eggs and prevents them from becoming rubbery. While you can use other milk varieties, whole milk or heavy cream will yield the most luxurious outcome.
• Fresh Vegetables: We’re using a trio of flavorful vegetables: sweet onion, red bell pepper, and thinly sliced zucchini. The sweet onion provides a gentle aromatic base, while the red bell pepper adds a touch of sweetness and vibrant color. The zucchini, a star of summer produce, should be sliced thinly to ensure it cooks quickly and evenly, becoming tender within the frittata without making it watery.
• Cheese Blend: A combination of sharp cheddar cheese and mozzarella cheese elevates this frittata. The sharp cheddar offers a bold, savory kick, while the mozzarella provides a wonderful melty texture and mild creaminess. This blend works beautifully with the eggs and vegetables, but feel free to experiment with your favorite cheeses if you prefer.
• Fresh Basil: Fresh basil brings a bright, aromatic, and slightly sweet-peppery note that screams summer. While dried basil can be substituted, the fresh herb truly enhances the overall flavor profile of the dish. Don’t skip it if you can help it!
• Key Spices: A thoughtful blend of spices takes this frittata from good to great. Oregano adds an earthy, slightly minty flavor that pairs well with Mediterranean ingredients, while a hint of crushed red pepper flakes introduces a subtle warmth and gentle heat, making the egg dish more dynamic and exciting. Adjust the red pepper to your spice preference.

How to Make a Delicious Zucchini Frittata

Crafting this zucchini frittata is a straightforward process, making it a joy to prepare. Follow these simple steps for a perfect, fluffy, and flavorful dish:

Step 1: Prepare the Egg Mixture: Begin by preheating your oven to 350 degrees F (175 degrees C). In a large mixing bowl, crack all 12 eggs. Add the 3 tablespoons of whole milk (or cream, for an extra rich texture). Whisk the mixture vigorously until the egg yolks and whites are thoroughly blended and slightly frothy, ensuring a uniform consistency for your frittata.

Step 2: Incorporate the First Batch of Cheese: Gently stir in 1/2 cup of shredded sharp cheddar cheese and 1/4 cup of the shredded mozzarella cheese into the whisked egg mixture. Mix until just combined, ensuring the cheese is evenly distributed throughout. Set this cheesy egg mixture aside for a moment.

Step 3: Sauté the Flavorful Vegetables: Heat the olive oil in a 12-inch non-stick oven-safe skillet or a well-seasoned cast-iron skillet over medium heat. Once shimmering, add the diced sweet onion, diced red bell pepper, and the thinly sliced zucchini. Stir in the oregano, crushed red pepper (if using), salt, and black pepper. Cook the vegetables, stirring occasionally, until they become tender and slightly softened, typically about 5-7 minutes. This step helps to develop their flavors and ensures they cook through evenly in the frittata.

Step 4: Combine Eggs and Vegetables: Give the reserved egg and cheese mixture another quick whisk to ensure everything is well-combined. Pour the whisked eggs evenly over the sautéed vegetable mixture in the skillet. Use a spatula to gently spread the vegetables so they are uniformly distributed throughout the eggs. Cook on the stovetop for about 1-2 minutes until the edges just begin to set.

Step 5: Add the Finishing Cheese Layer: Evenly sprinkle the remaining 1/2 cup of sharp cheddar cheese and the remaining 1/4 cup of mozzarella cheese over the top of the frittata. This final layer of cheese will melt into a golden, bubbly crust during baking, adding an extra layer of flavor and visual appeal.

Step 6: Bake to Golden Perfection: Carefully transfer the skillet to your preheated oven. Bake for approximately 30 minutes, or until the frittata appears beautifully puffed up, set in the center, and the edges are lightly golden brown. To check for doneness, give the pan a gentle shake; the center should not wobble. You can also insert a knife into the center; it should come out clean. Once baked, remove the frittata from the oven and allow it to cool for a few minutes before slicing. Cut it into neat triangles or wedges, garnish with fresh parsley or chives for an extra pop of color and flavor, and serve immediately. Enjoy your perfectly baked Zucchini Frittata!

For an ideal frittata, we highly recommend using a well-seasoned cast iron skillet or any high-quality, oven-safe non-stick skillet. The size of the skillet matters too; an 8 to 12-inch skillet is generally suitable, depending on the number of eggs you are using. A 12-inch skillet is perfect for this recipe’s 12 eggs, allowing the frittata to cook evenly without being too thin or too thick.

A perfectly cooked frittata will have a beautiful golden-brown top, appear slightly puffed up, and be set firmly in the center. A good test is to gently jiggle the pan; if the middle doesn’t wobble, it’s likely done. For absolute certainty, you can insert a thin knife or a wooden skewer into the center; it should come out clean, indicating the eggs are fully cooked through.

Absolutely! Frittatas freeze exceptionally well, making them an excellent meal prep option. To freeze, first allow the frittata to cool completely. Then, cut it into individual portions, wrap each portion tightly in plastic wrap, and then again in aluminum foil to prevent freezer burn. Store in an airtight freezer-safe bag or container for up to 2 months. You can reheat frozen portions directly in the oven (at 325°F/160°C for 20-30 minutes) or microwave, or simply thaw them overnight in the refrigerator before reheating.

Yes, this frittata is fantastic for make-ahead meals! You can prepare the entire frittata a day or two in advance and store it in the refrigerator. Reheat individual slices as described above, or gently warm the whole frittata in a low oven (around 300°F/150°C) until heated through. It tastes just as good, if not better, the next day!

Zucchini can release a lot of moisture when cooked, which might lead to a watery frittata. To prevent this, ensure you slice the zucchini thinly and sauté it thoroughly until it’s tender and most of its moisture has evaporated. You can also lightly salt the sliced zucchini and let it sit for 10-15 minutes, then pat it dry with paper towels before cooking to draw out excess water. This step is optional but highly recommended for the best texture.
