Ingredients
- 10 large eggs
- 1 cup fresh spinach, chopped (or 3/4 cup thawed frozen spinach, well squeezed)
- 3/4 cup feta cheese, crumbled
- 1/2 cup milk (dairy or unsweetened non-dairy)
- 1 small red onion, finely diced (about 1/2 cup)
- 1–2 cloves garlic, minced
- 2 tablespoons olive oil (for sautéing and greasing)
- 1/2 teaspoon kosher salt (plus more to taste)
- 1/4 teaspoon black pepper
- 1/4 teaspoon dried oregano (optional)
- Pinch of red pepper flakes (optional, for a little heat)
- Nonstick cooking spray or extra oil for muffin tin
How to Make It
- Prep the oven and pan: Preheat your oven to 350°F (175°C). Lightly grease a standard 12-cup muffin tin with cooking spray or a thin layer of olive oil. Make sure every cup is coated, including the top surface, to prevent sticking.
- Sauté the aromatics: Warm 1 tablespoon olive oil in a skillet over medium heat. Add the diced red onion and cook 3–4 minutes until softened. Stir in the garlic and cook 30 seconds more, just until fragrant. Remove from heat and let cool slightly.
- Wilt the spinach: If using fresh spinach, add it to the warm skillet (off heat) and toss until it softens. If using frozen spinach, thaw and squeeze it very dry in a clean towel. Excess moisture can make the muffins watery.
- Beat the eggs: In a large bowl, whisk the eggs with the milk, salt, pepper, oregano, and red pepper flakes until smooth and lightly frothy. Don’t overbeat; you just want a uniform mixture.
- Add the mix-ins: Stir in the sautéed onion and garlic, the spinach, and most of the feta (save a little to sprinkle on top). Mix gently to distribute everything evenly.
- Fill the muffin tin: Divide the mixture among the 12 cups, filling each about 3/4 full. Sprinkle the remaining feta on top for extra flavor and a pretty finish.
- Bake: Place on the middle rack and bake 16–20 minutes. The muffins are done when set in the center and a toothpick comes out clean. They will puff up in the oven and settle slightly as they cool.
- Rest and release: Let the muffins cool in the pan for 5 minutes. Run a thin knife around the edges to loosen, then lift them out and transfer to a rack to cool further.
- Taste and adjust: Sprinkle with a pinch of salt or pepper if needed. A quick squeeze of lemon or a few fresh herb leaves on top can brighten the flavors.
How to Store
- Refrigerate: Store in an airtight container for up to 4 days. Let them cool completely before sealing to avoid condensation.
- Freeze: Wrap each muffin tightly or place in a freezer bag, removing excess air. Freeze for up to 2 months.
- Reheat: Microwave chilled muffins for 20–30 seconds, or bake at 300°F (150°C) for 8–10 minutes. From frozen, microwave 45–60 seconds or reheat in the oven until warmed through.
Why This is Good for You
These muffins offer a strong protein base from eggs, which helps keep you full and steady your energy.
Spinach brings iron, folate, fiber, and antioxidants without many calories. Feta adds flavor, calcium, and a bit of fat, which increases satisfaction so you’re less tempted to snack.
Compared to many grab-and-go breakfasts, these are lower in refined carbs and sugar. You can also control the sodium and choose a milk that fits your diet.
The result is a balanced bite that works for mornings, post-workout, or a light lunch with a side salad.
Common Mistakes to Avoid
- Skipping the grease: Egg muffins love to stick. Coat the muffin tin well, including the flat surface around each cup.
- Too much moisture: Wet spinach or juicy vegetables can make the muffins soggy. Squeeze spinach dry and sauté watery veggies (like mushrooms) before mixing.
- Overbaking: Dry eggs are not fun. Start checking at 16 minutes and pull them as soon as the centers are set.
- Heavy mix-ins: Too many add-ins weigh the batter down. Keep the ratio balanced so the eggs stay fluffy.
- Under-seasoning: Eggs need salt. Taste a pinch of the cooked spinach and onions and adjust seasoning before baking.
Variations You Can Try
- Mediterranean: Add chopped sun-dried tomatoes, kalamata olives, and a pinch of dried basil with the feta.
- Protein boost: Stir in cooked turkey sausage, diced ham, or crumbled cooked bacon. Reduce salt slightly if your meat is salty.
- Veggie lovers: Mix in roasted bell peppers, zucchini, or mushrooms. Make sure they’re cooked and patted dry.
- Herb-forward: Fresh dill or parsley pairs beautifully with feta and spinach. Start with 2 tablespoons chopped fresh herbs.
- Dairy-free: Skip the feta and use a creamy dairy-free cheese or a tablespoon of nutritional yeast for a savory note. Choose unsweetened almond or oat milk.
- Spicy: Add a minced jalapeño or a dash of hot sauce to the egg mixture.
- Low-sodium: Use reduced-sodium feta or less cheese. Boost flavor with herbs, lemon zest, and black pepper.
FAQ
Can I use egg whites instead of whole eggs?
Yes. Replace the 10 whole eggs with about 2 cups of liquid egg whites.
The texture will be slightly lighter and less rich, and you may want to add an extra tablespoon of olive oil or a splash more milk for tenderness.
Do I need to use liners in the muffin tin?
You can, but silicone liners or a well-greased tin work best. Paper liners sometimes stick to egg muffins. If you use paper, lightly spray the inside of each liner.
How can I make these fluffier?
Whisk the eggs until just frothy and don’t overload the batter with mix-ins.
A tablespoon of plain Greek yogurt or cottage cheese whisked into the eggs can also make them extra tender.
What can I substitute for feta?
Try goat cheese for creaminess, or grated Parmesan for a sharper bite. Ricotta will make a softer, custardy texture. Adjust salt to taste depending on the cheese.
Are these good for kids?
Absolutely.
They’re mild, handheld, and easy to customize. Skip the red pepper flakes and chop the spinach very fine if you want a smoother texture.
Can I bake this as a casserole instead of muffins?
Yes. Pour the mixture into a greased 8×8-inch baking dish and bake at 350°F (175°C) for 22–28 minutes, or until the center is set.
Let it rest for 10 minutes before slicing.
How do I prevent a sulfur smell when reheating?
Don’t overheat. Short microwave bursts (10–15 seconds at a time) work well. Cover loosely with a damp paper towel to keep moisture in and stop the eggs from drying out.
Can I add potatoes or grains?
Sure.
A small amount of cooked, cooled diced potatoes or quinoa works well. Keep add-ins to about 1 to 1 1/2 cups total so the eggs stay the focus.
