Ingredients

  • Large eggs: this is the backbone of the muffin use the freshest you can find for best flavor

  • Salt and freshly ground black pepper: enhances flavor use sea salt and fresh peppercorns for a boost
  • Onion powder and garlic powder: these give great background depth look for pure spices with no additives
  • Finely chopped bell pepper: your choice of color for sweetness and crunch choose firm glossy peppers
  • Finely chopped tomatoes: for juicy bursts and brightness remove excess seeds if you want less moisture
  • Finely chopped fresh spinach or kale: packs in extra nutrients select deep green leaves for best quality

  • Optional garnishes: parsley chives parmesan or red pepper flakes add a fresh or spicy finishing touch

Feta cheese became my secret weapon for these muffins Its tangy flavor adds so much dimension My daughter once asked if I put magic in her breakfast and I honestly think fresh feta had something to do with it

Storage Tips

Once cooled keep egg muffins in an airtight container in the fridge for up to five days If freezing wrap muffins individually and store in a freezer safe container up to three months For reheating microwave wrapped in a damp towel for thirty seconds or heat in a low oven until warmed through Avoid overcooking or they will turn rubbery

Ingredient Substitutions

Use plant based milk for a dairy free version and swap out feta for a nondairy cheese If you do not have spinach any tender greens or even thawed frozen spinach work well Try cooked mushrooms cooked sausage or ham instead of the vegetables and use your favorite shredded cheese

Serving Suggestions

Egg muffins pair well with fresh fruit toast or a smoothie for a balanced meal For brunch lay out a platter with various dips salsa or hot sauce and a bowl of greens My kids love them tucked into English muffins for a breakfast sandwich

A Bit of History

Muffin tin frittatas are inspired by Italian frittata and popularized in American kitchens for their convenience Before muffin pans I used an 8 x 8 inch baking dish and would slice egg squares but the ease of these hand held muffins won everyone over in my family

Preheat oven to 191°C. Generously grease a 12-cup muffin pan with nonstick spray. Avoid using paper liners, or if using, spray liners thoroughly.

In a medium mixing bowl with a pour spout, whisk together eggs, milk, salt, black pepper, onion powder, and garlic powder until just combined. Do not over-mix.

Notes

  1. For optimal texture and flavor, bake muffins immediately after preparing the egg mixture.
  2. Prepared muffins keep refrigerated up to 5 days; reheat gently in the microwave or oven to prevent rubbery texture.
  3. To freeze, allow cooked muffins to cool completely, transfer to a freezer-safe container, and store for up to 3 months.
  4. Variety of add-ins such as diced cooked ham, mushrooms, cooked sausage, or other vegetables can be used, totaling approximately 225 g.
