How to Make the Best Breakfast Egg Muffins
Follow these simple steps for perfectly fluffy egg cups every time:
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 12-cup muffin tin with non-stick spray or use silicone muffin liners to prevent sticking.
Step 2: Mix the Eggs
In a large mixing bowl, whisk the eggs and milk together until light and frothy. The more you whip air into the eggs, the fluffier the egg muffins will be.
Step 3: Add Fillings
Chop your favorite vegetables and proteins into small, bite-sized pieces. Evenly distribute them among the muffin cups, filling each about halfway.
Step 4: Pour Egg Mixture
Pour the egg mixture over the fillings in each cup, filling almost to the top but leaving a small gap to allow room for rising.
Step 5: Bake
Place in the oven and bake for 20–25 minutes or until the tops are golden and a toothpick inserted in the center comes out clean.
Step 6: Cool and Serve
Let the egg muffins cool in the tin for about 5 minutes before removing. Serve warm or let them cool completely before refrigerating.
