Egg Base

  • Large eggs (10): The main base for fluffy muffins.
  • Milk (1/4 cup): Keeps the eggs tender and creamy.
  • Swap: Half-and-half for richer muffins.

Mix-Ins

  • Shredded cheddar (1 cup): Melty, savory flavor.
  • Swap: Monterey Jack, mozzarella, or Swiss.
  • Bell pepper, diced (1/2 cup): Sweet crunch and color.
  • Swap: diced zucchini (sauté first) or mushrooms (sauté first).
  • Spinach, chopped (1 cup): Adds color and nutrients.
  • Tip: Squeeze out extra moisture after chopping if it’s very wet.
  • Onion, finely diced (1/4 cup): Adds savory depth.
  • Swap: green onions for a milder taste.
  • Cooked crumbled sausage pieces (3/4 cup): Makes them extra filling.
  • Swap: cooked crumbled bacon or diced ham.

Seasoning

  • Salt (1/2 tsp): Brings out flavor.
  • Black pepper (1/2 tsp): Adds mild warmth.

How to Make Egg Muffins

Whisk, fill, pour, bake—fluffy egg muffins every time
  • 1. Preheat your oven to 350°F and spray a 12-cup muffin tin well (or use silicone liners).
  • 2. Sauté onion and bell pepper in a small skillet over medium heat for 3–4 minutes until slightly softened. This keeps your muffins from getting watery. Let cool 2 minutes.
  • 3. Whisk eggs, milk, salt, pepper, and garlic powder in a large bowl for 30–45 seconds, until the mixture looks smooth and slightly foamy.
  • 4. Divide spinach, sautéed veggies, sausage pieces, and cheese evenly among the muffin cups.
  • 5. Pour egg mixture into each cup, filling about 3/4 full. If it looks too full, stop—eggs puff up while baking.
  • 6. Bake for 18–22 minutes, until the centers are set and the tops look lightly golden. A knife inserted in the center should come out mostly clean.
  • 7. Cool for 5 minutes, then run a butter knife around the edges and lift out. If they sink a little as they cool, that’s normal.

Tips for Perfect Egg Muffins

  • Cook watery veggies first: Sauté peppers, onions, mushrooms, or zucchini so your muffins aren’t soggy.
  • Don’t overbake: Pull them when just set—overbaking makes eggs rubbery.
  • Fill 3/4 full: Eggs rise, and overfilled cups can spill.
  • Shred your own cheese: It melts smoother than pre-shredded.
  • Let them rest: 5 minutes helps them release from the pan cleanly.

Variations & Substitutions

  • Veggie-only: Skip sausage pieces and add extra spinach plus diced tomatoes (pat dry first).
  • Spicy version: Add a pinch of red pepper flakes or diced jalapeños (small amount).
  • Mediterranean twist: Use feta, chopped spinach, and diced olives.
  • Low-carb, extra protein: Add more eggs and reduce mix-ins slightly for firmer muffins.
  • Dairy-free: Use a dairy-free milk and skip cheese (or use dairy-free shreds).
  • Leftover idea: Chop an egg muffin and add to a breakfast burrito with salsa.

Storing & Reheating

Store Egg Muffins in an airtight container in the fridge for up to 4 days.
Reheat in the microwave for 20–40 seconds, until warm. For a slightly crisp edge, reheat in an air fryer at 350°F for 3–4 minutes.
Freeze for up to 2 months. Wrap individually and thaw overnight in the fridge, or microwave from frozen in short bursts until hot.

Serving Suggestions & Pairings

  • Pair with fruit and toast for a complete breakfast.
  • Add salsa or hot sauce on the side for extra flavor.
  • Serve with a simple side salad for a light lunch.
  • Perfect for road trips, school mornings, and meal prep snack boxes.
