Key Ingredients

For the Frittata Base:

• 4 large eggs
• 1 cup egg whites
• ½ tsp kosher salt
• Freshly ground black pepper

Aromatics & Vegetables:

• 1 tsp olive oil
• ½ cup red onion, finely chopped
• 3 scallions, chopped (white and green parts separated)
• 1½ cups fresh spinach, chopped

Cheeses & Toppings:

• 2 oz feta cheese, crumbled (plus more for topping)
• 2 tbsp Parmigiano-Reggiano, grated
• Diced grape tomatoes (optional)
• Extra chopped scallions (for garnish)

Step-by-Step Instructions

1. Preheat the Oven

Set your oven to 400°F. A hot oven ensures the top of the frittata sets quickly and puffs up beautifully.

2. Sauté Aromatics

Heat olive oil in a 9 or 10-inch oven-safe non-stick skillet over medium heat. Add red onion and the white parts of scallions. Cook for 3–4 minutes, until soft and fragrant.

3. Whisk the Eggs

In a bowl, whisk together whole eggs, egg whites, salt, and pepper until light and frothy.

4. Combine the Ingredients

Stir in the feta, Parmesan, sautéed onions, and chopped spinach. Gently mix until evenly combined.

5. Cook on the Stovetop

Pour the mixture back into the skillet. Cook undisturbed for 4–5 minutes, just until the edges are set but the center is still slightly jiggly.

6. Finish in the Oven

Transfer the skillet to the preheated oven. Bake for 4–5 minutes, or until the top is just set and lightly golden.

7. Cool & Serve

Remove from oven and let sit 2 minutes. Use a rubber spatula to loosen edges. Slice into 4 wedges and garnish with tomatoes, scallion greens, and extra feta.

Pro Tips for Success

✔ Let eggs come to room temperature for better rise and fluffier texture.
✔ Chop spinach finely so it blends evenly throughout the eggs.
✔ Use an oven-safe skillet to go seamlessly from stovetop to oven.
✔ Slightly underbake if meal prepping—frittata will finish cooking when reheated.

Serving Suggestions

• Pair with roasted potatoes and arugula salad for brunch.
• Tuck a slice into a toasted sourdough sandwich with cream cheese and tomatoes.
• Serve with pita, Greek yogurt, and cucumber salad for a Mediterranean twist.

Make It Your Own

• Southwest-style: Use pepper jack cheese, bell peppers, and top with avocado.
• French-inspired: Add sautéed mushrooms, leeks, and Gruyère.
• Hearty version: Fold in roasted sweet potatoes and fresh sage.

Storage & Reheating

• Refrigerate: Store slices in an airtight container for up to 4 days.
• Freeze: Wrap individually in plastic and foil, then freeze for up to 3 months.
• Reheat: Bake at 300°F for 8–10 minutes or microwave individual slices for 30–45 seconds.
