Spinach Feta Egg Muffins

Quick Answer

Whisk eggs with milk, divide spinach, feta, bell pepper, and green onions among a greased muffin tin, then pour in the egg mixture. Bake at 350°F for 18 to 20 minutes until puffed and set, then cool 5 minutes before releasing.

Jump to Recipe

Egg muffins are what happens when breakfast decides it would like to be stackable. These use ten eggs with a splash of milk, chopped spinach, crumbled feta, red bell pepper, and green onion, divided across a standard 12-cup muffin tin and baked until the centers are set. Greasing the pan generously is not optional housekeeping. Eggs cling to metal with the loyalty of a relative who heard you bought a lake house. Butter or cooking spray gives you a fighting chance at clean release once the muffins have cooled for five minutes. Fill each cup about three-quarters full; the eggs puff in the oven, then settle slightly as they cool, which is normal and not evidence that breakfast has failed.

The feta does most of the seasoning work alongside salt and pepper, spinach adds bulk without making the muffins heavy, and the bell pepper and green onion keep every bite from tasting identical. At 350°F they need about 18–20 minutes, with no jiggle in the center when the pan is gently shaken. Make a dozen once and breakfast becomes significantly less theatrical for the next few mornings.

Ingredients

Servings
  • Cooking spray or butter, for the pan
  • 10 large eggs
  • 1/4 cup milk
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 cups fresh baby spinach, chopped
  • 1/2 cup crumbled feta cheese
  • 1/4 cup diced red bell pepper
  • 2 green onions, thinly sliced

Instructions

  1. 1Preheat oven to 350°F. Generously grease a 12-cup muffin tin with cooking spray or butter -- eggs stick more than batter, so don't skip this.
  2. 2In a large bowl, whisk the eggs, milk, salt, and pepper until fully combined.
  3. 3Divide the spinach, feta, bell pepper, and green onions evenly among the muffin cups.
  4. 4Pour the egg mixture over the vegetables and cheese in each cup, filling about 3/4 full.
  5. 5Bake for 18 to 20 minutes, until the egg muffins are puffed, set in the center, and no longer jiggle when the pan is gently shaken.
  6. 6Let cool in the pan for 5 minutes -- they'll deflate slightly, that's normal -- then run a knife around the edges to release and serve warm.

Pro Tips

  • Grease the tin well, even if it's nonstick. Eggs are more prone to sticking than muffin batter, and skipping this step means torn muffins.
  • Don't overfill the cups. Eggs puff a lot in the oven, and overfilled cups will overflow.
  • Chop the spinach so it distributes evenly instead of clumping in one or two muffins.

Substitutions

feta → shredded cheddar or goat cheese Any crumbly or shreddable cheese works.
baby spinach → chopped kale or chopped broccoli, lightly steamed first Steaming first prevents excess water from making the eggs watery.
whole eggs → 1 cup liquid egg whites plus 4 whole eggs Lightens the muffins while keeping enough yolk for flavor and structure.
