Ingredients Overview

These egg muffins rely on simple, whole ingredients — and they’re flexible enough for whatever you have in the fridge.

Eggs:

  • Large eggs (6–8 depending on muffin size)
    A protein-packed base that sets up light and fluffy in the oven.

  • Optional: Add 1–2 egg whites for lighter texture or added volume.

Dairy:

  • Crumbled feta cheese (½ cup)
    Adds a briny, creamy bite that pairs beautifully with spinach.

  • Optional: Shredded mozzarella or goat cheese for variation.

Vegetables:

  • Fresh spinach (1–2 cups chopped)
    You can sauté it briefly or chop it raw — both work. Frozen spinach is also fine if squeezed dry.

  • Red bell pepper, green onions, or tomatoes (optional)
    Add color, crunch, and extra nutrients.

Seasoning:

  • Salt and pepper – A pinch goes a long way since feta is salty.

  • Garlic powder or Italian herbs – Optional, but adds depth.

  • Chili flakes – For a subtle kick, if desired.

Step-by-Step Instructions

1. Preheat & Prep

  • Preheat your oven to 350°F (175°C).

  • Lightly grease a 12-cup muffin tin with nonstick spray or line with silicone muffin cups.

2. Sauté the Spinach (Optional)

  • In a skillet, warm 1 tsp olive oil and quickly sauté the spinach until just wilted.

  • Let cool slightly before adding to the egg mix.

  • Note: You can skip this step if using chopped fresh spinach or thawed frozen spinach.

3. Whisk the Eggs

  • Crack 6–8 eggs into a large bowl.

  • Whisk well with a fork or balloon whisk until fully combined.

  • Add salt, pepper, and any additional seasoning.

4. Stir in Fillings

  • Add sautéed or raw spinach, crumbled feta, and any chopped vegetables.

  • Stir to combine evenly — don’t overmix.

5. Pour & Bake

  • Pour the mixture evenly into the muffin cups, filling each about ¾ full.

  • Bake for 18–22 minutes, or until the muffins are puffed and set in the center.

  • Let cool in the pan for 5 minutes before removing.

6. Cool & Store

  • Serve warm, or cool completely and refrigerate in an airtight container.

  • Reheat in the microwave for 20–30 seconds when ready to eat.

Tips, Variations & Substitutions

Tips:

  • Avoid rubbery eggs by not overbaking — remove as soon as centers are set.

  • Use a silicone muffin tray or muffin liners for easier cleanup.

  • These egg muffins will puff in the oven and slightly deflate as they cool — that’s normal.

Variations:

  • Mediterranean: Add sun-dried tomatoes, Kalamata olives, and oregano.

  • Tex-Mex: Swap feta for cheddar, add black beans and jalapeños.

  • Protein Boost: Stir in chopped turkey sausage or cooked chicken.

Substitutions:

  • Dairy-free? Use a vegan cheese or skip it altogether — the muffins still hold together well.

  • No spinach? Kale, arugula, or zucchini all work beautifully.

  • Low-fat version: Use egg whites or a 50/50 mix of whole eggs and whites.

Serving Ideas & Occasions

These muffins are perfect for:

  • Meal prep – Make a batch on Sunday and enjoy all week.

  • Grab-and-go breakfast – Just heat and eat.

  • Brunch platters – Serve alongside fruit and toast for a light but satisfying meal.

  • Afternoon snacks – Healthy, protein-packed, and easy to keep on hand.

Pair With:

  • Fresh fruit or a banana

  • Greek yogurt or cottage cheese

  • A slice of whole grain or sourdough toast

  • A smoothie or matcha latte for a balanced morning

FAQs

Q1: How long do egg muffins last in the fridge?

A: They keep well for 4–5 days in an airtight container in the refrigerator. Reheat briefly before serving.


Q2: Can I freeze egg muffins?

A: Yes. Let them cool completely, wrap individually or store in a freezer bag, and freeze for up to 2 months. Reheat in the microwave straight from frozen for 60–90 seconds.


Q3: Can I make these in advance?

A: Absolutely. These are one of the best make-ahead breakfasts. You can prep them the night before or bake a big batch for the week.


Q4: Do I need to sauté the spinach?

A: Not always. You can chop raw spinach finely and add it directly to the egg mix. For frozen spinach, thaw and squeeze out excess moisture before using.


Q5: Why did my egg muffins collapse?

A: Egg muffins naturally puff up and deflate slightly as they cool. To prevent major collapse, avoid overbeating the eggs and don’t overbake.


Q6: Can I add meat?

A: Yes! Cooked bacon, turkey sausage, or diced ham all work well. Just keep the add-ins chopped small so they distribute evenly.


Q7: What kind of feta is best?

A: Use crumbled feta in brine for the best flavor and moisture. You can also use reduced-fat feta or goat cheese for a lighter option.
