Ingredients

Scale

6 large eggs
1/4 cup whole milk
1/2 cup shredded cheddar cheese
1/4 cup diced red bell pepper
1/4 cup diced green bell pepper
1/4 cup finely chopped spinach
1/4 cup finely chopped onion
1/4 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon baking powder
1 tablespoon olive oil

Instructions

Preheat the oven to 350°F (175°C).
Lightly grease a 6-cup muffin tin with olive oil.
In a large mixing bowl, crack the eggs and whisk together with the whole milk until fully combined and slightly frothy.
Add the baking powder, salt, and black pepper to the egg mixture and whisk again.
Fold in the shredded cheddar cheese, diced red bell pepper, diced green bell pepper, chopped spinach, and chopped onion until evenly distributed.
Pour the egg mixture evenly into the prepared muffin tin cups, filling each about 3/4 full.
Place the muffin tin in the preheated oven and bake for 18 to 20 minutes, or until the egg muffins are puffed up, golden on top, and a toothpick inserted into the center comes out clean.
Remove the muffin tin from the oven and allow the egg muffins to cool for 5 minutes before removing them from the tin.
Serve warm or store in an airtight container in the refrigerator for up to 4 days.
