The beauty of a frittata lies in its simplicity and versatility. Unlike its cousin the omelet, which requires last-minute attention and perfect timing, a frittata begins on the stovetop and finishes in the oven, giving you breathing room to prepare other elements of your meal. The tender zucchini and burst cherry tomatoes create pockets of moisture and flavor throughout the light, airy egg base.

• Vegetables: 1 medium zucchini (thinly sliced), 1 cup cherry tomatoes (halved), 1 small yellow onion (finely chopped), 2 cups baby spinach (optional)
• Eggs & Dairy: 6 large eggs, 2 tablespoons skim milk (or unsweetened plant milk), 1/4 cup grated Parmesan cheese (optional), salt and freshly ground black pepper to taste
• Herbs & Spices: 1/4 cup fresh basil leaves (chopped, or 1 tsp dried basil), 1/2 teaspoon dried oregano, 1 clove garlic (minced)
• Oils: 1 tablespoon olive oil (or nonstick cooking spray)

Prepare the oven

Preheat oven to 375°F (190°C).

Sauté the base

In a large oven-safe skillet, heat olive oil over medium heat. Add onion and sauté for 2 minutes until softened.

Cook the zucchini

Add zucchini and cook for 4–5 minutes, stirring occasionally, until just tender. Add garlic and cook for 1 minute.

Add remaining vegetables

Add cherry tomatoes and spinach (if using); cook for 2 more minutes until spinach is wilted and tomatoes start to soften.

Prepare the egg mixture

In a bowl, whisk together eggs, skim milk, Parmesan (if using), basil, oregano, salt, and pepper.

Combine and start cooking

Pour egg mixture over vegetables in skillet, stirring gently to distribute. Cook undisturbed for 2–3 minutes until edges begin to set.

Finish in the oven

Transfer skillet to the oven and bake for 10–12 minutes, or until the frittata is puffed and the center is just set.

Serve

Remove from oven, cool for 2 minutes, then slice and serve warm or at room temperature.

The key to a perfect frittata is gentle cooking - avoid high heat which can make eggs rubbery. Make sure your oven-safe skillet can go directly from stovetop to oven for the most efficient preparation. If you're uncertain, you can transfer the partially-cooked mixture to a greased baking dish before putting it in the oven, though you'll miss some of the crispy edge texture.

This frittata welcomes adaptation based on what you have on hand. Try swapping zucchini for yellow summer squash, or use roasted red peppers in place of tomatoes. For a more substantial meal, add small cubes of cooked potato or sweet potato. Make it dairy-free by omitting the Parmesan or using nutritional yeast for a cheesy flavor without the dairy. For meat lovers, adding a small amount of diced prosciutto or cooked bacon adds a savory depth without significantly increasing calories.

Serve slices of this light frittata with a simple arugula salad dressed with lemon juice and a drizzle of extra virgin olive oil for a complete meal. For brunch, pair with toasted whole grain bread or roasted sweet potatoes. A side of fresh fruit provides a sweet counterpoint to the savory eggs. Garnish with additional fresh herbs just before serving to brighten both the presentation and flavor.
