Spinach & Feta Egg Muffins: High-Protein Breakfast in 20 Minutes

If you've ever rushed out the door with nothing more than a cup of coffee and a grumbling stomach, you're not alone. Busy mornings make it tempting to skip breakfast or grab something sugary on the way to work. But with a little planning, you can enjoy a nutritious, high-protein breakfast in just 20 minutes. One of the easiest and tastiest solutions is Spinach & Feta Egg Muffins. These savory, fluffy little bites are packed with protein, rich in vitamins, and perfect for meal prep.
Why These Egg Muffins Belong in Your Breakfast Rotation
High in Protein for Lasting Energy
Eggs are one of nature's best sources of complete protein, providing all nine essential amino acids. Each muffin delivers about 6–7 grams of protein, helping you feel satisfied for hours and preventing mid-morning sugar crashes.
Nutrient-Dense Without the Guilt
Spinach adds a hefty dose of vitamin K, vitamin C, iron, and antioxidants. Pairing it with calcium-rich feta gives you an extra boost for strong bones and a healthy immune system, all with fewer calories than many traditional breakfast options.
Meal Prep Magic
These muffins can be made ahead of time and stored in the fridge for up to five days or frozen for up to three months. A quick reheat in the microwave or oven gives you a hot breakfast in seconds.
Customizable to Your Taste
Don't like feta? Swap in goat cheese or cheddar. Want more veggies? Add diced bell peppers, mushrooms, or zucchini. You can also spice things up with chili flakes or a pinch of smoked paprika.
Perfect for All Lifestyles
Whether you're following a low-carb, keto, or gluten-free plan, these egg muffins fit right in. They're naturally grain-free and pack a lot of nutrients without any processed ingredients.
Ingredients You'll Need
To make a batch of 12 muffins (about six servings), gather these simple ingredients:
Main Ingredients
- 10 large eggs
- 2 cups fresh spinach, roughly chopped
- ½ cup crumbled feta cheese
- ¼ cup milk (dairy or unsweetened plant-based)
- 2 cloves garlic, minced (optional for extra flavor)
- Salt & freshly ground black pepper, to taste
- 1 tablespoon olive oil or butter, for greasing
Optional Add-ins
Optional add-ins: diced onions, bell peppers, cherry tomatoes, or fresh herbs like parsley or dill.
Step-by-Step Instructions
Step 1: Preheat and Prep
Heat your oven to 375°F (190°C). Lightly grease a 12-cup muffin pan with olive oil or non-stick spray.
Tip: You can also line with silicone muffin cups for easy cleanup.
Step 2: Sauté the Spinach
In a skillet over medium heat, add a drizzle of olive oil and sauté the garlic until fragrant. Toss in the spinach and cook just until wilted, about 1–2 minutes. Remove from heat and set aside.
Step 3: Whisk the Eggs
In a large mixing bowl, whisk the eggs and milk until smooth. Season generously with salt and pepper.
Step 4: Add the Fillings
Stir in the sautéed spinach and crumbled feta. If you're adding extra veggies or herbs, fold them in now.
Step 5: Fill and Bake
Divide the mixture evenly among the muffin cups. Bake for 15–18 minutes, or until the egg muffins are set and slightly golden on top.
Step 6: Cool and Store
Allow the muffins to cool for 5 minutes before removing them from the pan. Store leftovers in an airtight container in the fridge or freezer.
Spinach & Feta Egg Muffins are a low-carb, high-protein breakfast you can prepare in under 20 minutes. Simply whisk eggs with fresh spinach, crumbled feta cheese, and your favorite herbs, pour the mixture into a muffin tin, and bake.

6 Detailed FAQs About Egg Muffins
Q1: Can I make these egg muffins dairy-free?
A: Yes! Replace the feta with a dairy-free cheese alternative or skip the cheese entirely. You can also use unsweetened almond or oat milk instead of cow's milk.
Q2: How can I increase the protein even more?
A: Add diced cooked turkey or chicken breast, or sprinkle in a spoonful of nutritional yeast for an extra protein kick.
Q3: Do I have to sauté the spinach first?
A: It's recommended because raw spinach releases water during baking. Lightly sautéing prevents excess moisture and keeps the muffins fluffy.
Q4: Can I make these ahead for the whole week?
A: Absolutely. Store them in the fridge and reheat each morning. They maintain their texture and flavor for up to five days.
Q5: Will these muffins work for a keto or low-carb diet?
A: Yes, each muffin contains only about 1–2 grams of carbs, making them perfect for keto or other low-carb plans.
Q6: What if I don't have a muffin tin?
A: You can pour the mixture into a greased 8x8-inch baking dish and bake as a frittata. Cut into squares once cooled.
