Instructions

  1. Step 1: Preheat oven to 375°F and lightly grease a 6-cup muffin tin with 1 tbsp olive oil to prevent sticking.
  2. Step 2: Whisk 6 large eggs in a medium bowl with 1/4 tsp salt and 1/8 tsp black pepper until evenly blended and slightly frothy.
  3. Step 3: Stir in 1/2 cup finely diced yellow onion and 2 cups chopped fresh spinach until evenly distributed, then fold in 1/4 cup shredded sharp cheddar cheese.
  4. Step 4: Divide the mixture evenly into the greased muffin cups, filling each about 3/4 full to allow for rising.
  5. Step 5: Bake for 20-25 minutes until the eggs are set and tops are lightly golden, with a slight jiggle in the center when gently shaken.
  6. Step 6: Let rest in the tin for 5 minutes to set completely before carefully removing with a knife.
