These beauties come together with just a handful of simple ingredients—probably already in your fridge! Here’s exactly what you’ll need (and yes, I’ve learned the hard way that measurements matter here):
- 1 cup liquid egg whites (the carton kind—no separating required!)
- 1/4 cup diced bell peppers (any color—I’m partial to red for sweetness)
- 1/4 cup diced onions (yellow or white both work great)
- 1/4 cup chopped spinach (fresh, not frozen—trust me on this texture thing)
- 1/4 teaspoon salt (don’t skip—it makes the flavors pop!)

- 1 tablespoon olive oil (for greasing—your muffins will thank you)
Ingredient Substitutions
Out of something? No panic! Try these swaps: mushrooms for bell peppers (more earthy flavor), almond milk for egg whites (use 1:1 but texture gets softer), or kale for spinach (chop extra fine). Cheese lovers? Toss in 2 tbsp feta—it’s life-changing!

How to Make Egg-White Frittata Muffins
Don’t let the fancy name fool you—these are easier than hitting snooze! Just follow these simple steps for perfect little protein clouds every time:
- Preheat to 350°F (175°C)—this gives your oven time to get nice and toasty before the muffins go in.
- Grease that tin like you mean it! Use olive oil or nonstick spray in every nook—nobody likes a stuck muffin.
- Whisk egg whites with salt, pepper, and garlic powder until a bit frothy (about 30 seconds).
- Divide veggies evenly among the cups—I use a tablespoon to keep things fair.
- Pour egg mixture over veggies, filling each cup ¾ full (they puff up like little soufflés!).
- Bake 20 minutes until centers feel firm when gently tapped—no jiggles allowed!
- Cool 5 minutes before gently running a knife around the edges—patience prevents crumbles.
Pro Tips for Perfect Muffins
After burning enough muffins to start a bonfire, here’s what I’ve learned:
- Don’t overfill! Leave ¼ inch space—egg whites expand like excited popcorn.
- Silicone molds are cheat codes for zero-stick results (and fun colors!).
- Pat veggies dry—soggy spinach = sad, watery muffins.
- No peeking! Keep that oven door shut for the first 15 minutes.
- Room temp eggs blend smoother—I leave mine out while prepping veggies.

Customizing Your Egg-White Frittata Muffins
The beauty of these muffins? You can tweak them to match your mood, diet, or whatever’s wilting in your veggie drawer! Here are my favorite ways to mix things up:
- Cheese lovers: Crumble in 2 tbsp feta or goat cheese per batch—it creates little salty pockets of joy
- Meat fans: Swap half the veggies for diced turkey bacon or ham (perfect for post-workout protein)
- Keto crew: Add diced avocado after baking—the creaminess against the fluffy eggs is *chef’s kiss*
- Veggie-loaded: Try broccoli florets or zucchini instead of peppers—just chop them small so they cook through
My latest obsession? A sprinkle of everything bagel seasoning on top before baking—gives that deli-style flavor without the carbs!
Storing and Reheating Egg-White Frittata Muffins
These muffins disappear fast in my house, but when they do last (rarely!), here’s how to keep them fresh:
- Fridge storage: Tuck cooled muffins in an airtight container—they’ll stay perfect for 3 days
- Reheating magic: 30 seconds in the microwave brings back that just-baked fluffiness
- Freezer warning: Skip it! Egg whites get rubbery when frozen—trust me, I learned the hard way
Pro tip: Stack them with parchment paper between layers to prevent sticking—your future self will thank you!

FAQs About Egg-White Frittata Muffins
Got questions? I’ve got answers! Here are the things people ask me most about these little protein powerhouses:
Can I use whole eggs instead of egg whites?
Absolutely! Swap 1 cup egg whites for 4 whole eggs—just know they’ll be richer (and about 70 calories per muffin). Still delicious!
Why do my muffins stick to the pan?
Two culprits: not enough grease (really coat those cups!) or trying to remove them too soon. Let them cool 5 minutes—patience is key!
How do I prevent sogginess?
Dry those veggies! After chopping, press spinach and peppers between paper towels. Wet ingredients = sad, mushy muffins.
Can I make these ahead for meal prep?
You bet! They keep beautifully for 3 days in the fridge. Just reheat for 30 seconds—good as fresh!
Why didn’t my muffins puff up?
Overmixing is the usual suspect. Gently fold ingredients—you want some air in those egg whites for maximum fluff!
