• 1/2 cup diced bell peppers (any color)
• 1/3 cup diced red onion
• 1/2 cup chopped baby spinach
• 1/3 cup cherry tomatoes, halved (optional but tasty)
• 1/4 cup crumbled feta or shredded mozzarella (optional)
• 1–2 tablespoons chopped fresh herbs (parsley, chives, or basil)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon smoked paprika (or chili flakes for heat)
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon black pepper
• Olive oil spray (or avocado oil spray)

Cooking Instructions

1. Prep the pan: Line a small, air-fryer-safe pan or 7–8 inch square cake pan with parchment and spray lightly with oil. Make sure it fits your air fryer basket.
2. Preheat: Set air fryer to 325°F (163°C) for 3 minutes so it’s ready to go.
3. Whisk the base: In a bowl, whisk egg whites with salt, pepper, garlic powder, onion powder, and smoked paprika until lightly frothy.
4. Load the goods: Add peppers, onion, spinach, tomatoes, and herbs. Stir to distribute.If using cheese, sprinkle half into the mix and reserve half for the top.
5. Pour and level: Pour the mixture into the lined pan. Tap gently to pop big bubbles. Top with remaining cheese if using.
6. Air fry: Cook at 325°F for 10–14 minutes, depending on thickness and your air fryer.The center should be set and no longer jiggly.
7. Rest and release: Let sit 2–3 minutes. Lift using the parchment, transfer to a board, and slice into 4–6 rectangles.
8. Finish like a pro: Optional—sprinkle a little flaky salt, hot sauce, or fresh herbs. Serve warm.

Storage Instructions

• Fridge: Store slices in an airtight container for up to 4 days.Separate layers with parchment to avoid sticking.
• Reheat: Air fryer at 300°F for 3–4 minutes or microwave for 30–60 seconds. Air fryer keeps the edges crisp, IMO.
• Freeze: Wrap individually and freeze up to 2 months. Thaw overnight in the fridge, then reheat as above.

What’s Great About This

• Macro-friendly: Egg whites mean plenty of protein without extra fat.Add cheese or avocado if you want richer macros.
• Vegetable delivery system: You’ll accidentally eat a serving of veggies before 9 a.m. Mom would be proud.
• Batch power: Make a pan, slice, and stack your week. Breakfast becomes a non-issue.
• Low mess: One bowl, one pan, minimal cleanup.The dream.
• Anytime meal: Breakfast, post-workout snack, or light dinner with a side salad.

Don’t Make These Errors

• Skipping parchment or oil: Egg whites love to stick. Line the pan and spray it—future you will thank you.
• Overfilling the pan: Too thick and the center won’t set evenly. Aim for a 3/4–1 inch layer.
• Cranking the heat: High temps make rubbery whites. 325°F is the sweet spot for tender slices.
• Adding watery veggies raw: Tomatoes and mushrooms can release moisture.Pat dry or sauté briefly if you’re heavy-handed.
• Undersalting: Egg whites need seasoning. Taste your mix (yes, a tiny dab) or measure confidently.

Mix It Up

• Mediterranean: Feta, spinach, sun-dried tomatoes, oregano, and olives.
• Southwest: Corn, black beans, jalapeño, cheddar, and a dash of cumin. Finish with salsa.
• Lean & Green: Zucchini, asparagus tips, parsley, and lemon zest.Light, bright, chef-y.
• Meaty: Turkey bacon or chicken sausage crumbles for extra protein. Keep pieces small.
• Caprese-ish: Cherry tomatoes, basil, mozzarella; drizzle with balsamic glaze after cooking.
• Herb bomb: Chives, dill, tarragon, and parsley. Elegant and super fresh.

FAQ

Can I use whole eggs instead of egg whites?

Yes.

Substitute 10 large eggs for the 2 cups of whites and reduce salt slightly. Cooking time may be 1–2 minutes longer due to added fat and richness.

What kind of pan works in the air fryer?

Use a 7–8 inch square cake pan, small casserole, or any oven-safe pan that fits your basket. Silicone molds also work, but they may need an extra minute to set because they insulate heat.

Why did my frittata turn rubbery?

It was likely cooked at too high a temperature or for too long.

Keep the temp at 325°F and pull it once the center is just set. Overcooking egg whites is a one-way ticket to Bounce City.

How do I prevent excess moisture?

Pat juicy veggies dry and avoid overloading. If using mushrooms or very ripe tomatoes, sauté briefly first.

Also, rest the frittata a couple minutes before slicing so steam escapes cleanly.

Can I make these in muffin cups?

Absolutely. Grease or line silicone muffin cups, fill 3/4 full, and air fry at 325°F for 8–10 minutes. Great for grab-and-go portions and lunchboxes.

What sauces pair well?

Hot sauce, salsa verde, pesto, chimichurri, or a light yogurt-garlic sauce.

Even a little sriracha + honey mix if you like sweet heat.

How do I scale this for meal prep?

Double the recipe and use a larger pan that fits your air fryer, or cook two batches. Cool completely, slice into 8–10 pieces, and store in airtight containers with parchment between layers.

Is there a dairy-free option?

Yes—just skip cheese or use a dairy-free cheese. For richness, add a teaspoon of olive oil or a splash of unsweetened almond milk to the egg whites.
