Egg Muffins with Spinach and Feta
I learned to love these egg muffins the week my mornings turned chaotic—quick to make, endlessly flexible, and they travel well. Egg Muffins with Spinach and Feta are savory, handheld frittatas baked in a muffin tin. They’re perfect for busy breakfasts, protein-packed snacks, or a light brunch spread. If you like portable morning food that tastes fresh and wholesome, these are the answer. If you need more hearty brunch ideas, try this simple chicken and spinach casserole for a crowd-pleaser.
What makes this recipe special
These muffins hit a lot of marks: they’re fast, budget-friendly, and freezer-friendly. The tangy, salty feta brightens the eggs while spinach sneaks in a serving of greens. They’re also naturally gluten-free and easy to adapt for low-carb or Mediterranean-inspired meals. Make them for weekday meal prep, pack them for kids’ lunchboxes, or serve a batch at a weekend brunch with coffee.
“I made these for weekday breakfasts and they’ve been my go-to—simple, filling, and I love how the feta keeps each muffin flavorful.”
I often pair this kind of protein-centric bake with other make-ahead dishes like a creamy chicken and spinach casserole when I’m hosting, because both travel and reheat well.
Preparing Egg Muffins with Spinach and Feta
Overview: Whisk eggs, fold in chopped spinach, crumbled feta, diced bell peppers and onion, season, then spoon into a greased muffin tin and bake until set. Expect about 20–25 minutes of oven time and minimal hands-on prep—most of the work is chopping. These cook up quickly, and you’ll end with individual portions that are easy to reheat.
- Prep time: ~10 minutes
- Cook time: 20–25 minutes
- Total time: 30–35 minutes
- Yield: About 6 standard-sized muffins (depends on muffin tin size—use a 12-cup tin for smaller, 2-bite portions)
What you’ll need
- 6 large eggs
- 1 cup fresh spinach, chopped (substitute: thawed, well-drained frozen spinach or chopped kale)
- 1/2 cup feta cheese, crumbled (substitute: goat cheese or feta-style vegan cheese)
- 1/4 cup bell peppers, diced (any color)
- 1/4 cup onion, diced (white, yellow, or red)
- Salt and pepper to taste
- Cooking spray or olive oil for greasing (or use silicone liners)

Directions to follow
- Preheat the oven to 350°F (175°C). Position a rack in the center of the oven.
- Crack the eggs into a mixing bowl and whisk until yolks and whites are fully combined and slightly frothy. This creates a lighter texture.
- Stir in the chopped spinach, crumbled feta, diced bell peppers, diced onion, and a pinch of salt and generous black pepper. Mix gently so you don’t break up the feta too much.
- Grease a muffin tin with cooking spray or brush with olive oil. For easy removal, silicone liners or a nonstick pan help.
- Pour or ladle the egg mixture into each muffin cup, filling each about two-thirds full to allow room for slight puffing.
- Bake 20–25 minutes, until the edges are set and the tops are lightly golden. A toothpick inserted in the center should come out mostly clean.
- Let the muffins cool in the pan for 3–5 minutes, then run a small knife around the edges and lift out. Cool slightly before stacking or packing.
If you prefer a firmer texture, bake a few minutes longer; for softer centers, pull them at the lower end of the time range.
Best ways to enjoy it
Serve warm or at room temperature. Ideas:
- Breakfast on the go: wrap a muffin in a paper towel and tuck into a travel mug.
- Brunch platter: place muffins alongside sliced tomatoes, avocado, and crusty bread. Pair with a simple fruit salad. Consider a Mediterranean pairing like this Greek orzo with tomatoes, olives, basil and feta for a fuller spread.
- Snack or post-workout: enjoy with a smear of plain Greek yogurt or a dab of pesto.
- Lunchbox tip: add a small ice pack and they’ll remain safe and tasty for a few hours.
Storage and reheating tips
- Refrigerator: Store cooled muffins in an airtight container for up to 4 days. Keep them chilled within two hours of baking to follow safe food-handling practices.
- Freezer: Freeze in a single layer on a baking sheet until firm, then transfer to a labeled freezer bag for up to 3 months. Separate layers with parchment.
- Reheating: Microwave from refrigerated, 20–40 seconds per muffin (depending on microwave). For a crisper edge, reheat in a 325°F oven for 8–10 minutes or in a toaster oven until warmed through. From frozen, microwave 60–90 seconds or thaw overnight in the fridge and reheat as above.
Always reheat until the center reaches a safe serving temperature and discard any muffins left at room temperature longer than 2 hours.
Pro chef tips
- Don’t overbeat eggs—beat just enough to combine. Overbeating introduces air that can collapse after baking, making a rubbery texture.
- Squeeze excess moisture from any thawed frozen spinach to avoid soggy muffins.
- Keep fillings roughly uniform in size so each bite has balanced flavor.
- Use a metal spoon or small ladle for even portioning; this keeps bake times consistent.
- If using pre-shredded cheese, note it often contains anti-caking agents that can change melt behavior—crumbled blocks give the best texture. For ideas about using extra eggs in other recipes, I like referencing an egg salad with jalapeño and cheddar for leftover egg inspiration.
Creative twists
- Mediterranean: add chopped sun-dried tomatoes, olives, and oregano; swap feta for goat cheese.
- Mexican-style: replace feta with crumbled queso fresco, add chopped cilantro, jalapeño, and a pinch of cumin.
- Meat-lover: fold in cooked crumbled sausage or diced ham (cook first).
- Veg-loaded: add grated zucchini (squeeze moisture), mushrooms, or shredded carrots.
- Low-fat: use 3 egg whites plus 2 whole eggs; reduce the feta slightly and add herbs for flavor.
Your questions answered
Q: How many muffins will 6 eggs make?
A: That depends on muffin cup size. Using standard 1/2-cup muffin cups, 6 eggs yield about 6 muffins. For smaller, 12-cup tins, you’ll get more, but with smaller individual servings.
Q: Can I use frozen spinach?
A: Yes—thaw and squeeze out all excess water before adding. Excess moisture will make the muffins watery and lengthen baking time.
Q: Are these freezer-friendly?
A: Absolutely. Freeze fully cooled muffins up to 3 months. Thaw overnight in the fridge or reheat from frozen in the microwave or oven.
Q: Can I omit dairy for a dairy-free version?
A: Replace feta with a dairy-free crumbly alternative or omit the cheese and add extra herbs and a pinch of nutritional yeast for savory depth.
Q: How do I know when they’re done?
A: The tops should be set and slightly golden. A toothpick in the center should come out mostly clean with only a few moist crumbs.
