These easy breakfast egg muffins are a simple, protein-rich breakfast made with eggs, colorful vegetables, and optional cooked beef. They’re perfect for meal prep and busy mornings.
Ingredients
- 6 large eggs
- ¼ cup milk
- ¼ cup diced onion
- ¼ cup diced green bell pepper
- ¼ cup cooked beef, chopped (optional)
- Salt, to taste
- Black pepper, to taste
- Non-stick spray or butter, for greasing
Instructions
- Preheat the oven to 350°F (180°C). Grease a 6-cup muffin tin with non-stick spray or butter.
- Add the fillings. Divide the diced onion, bell pepper, and cooked beef evenly among the muffin cups.
- Whisk the eggs. In a bowl, whisk together the eggs, milk, salt, and black pepper until well combined and slightly frothy.
- Fill the muffin cups. Pour the egg mixture over the vegetables and beef, filling each cup about ¾ full.
- Bake for 20–25 minutes, or until the muffins are puffed and lightly golden and the eggs are fully set.
- Cool and serve. Let the muffins cool for about 5 minutes before removing them from the pan.
Tips for Perfect Egg Muffins
- Don’t overfill the muffin cups because the eggs expand while baking.
- Chop vegetables into small pieces so they cook evenly.
- Sauté watery vegetables such as spinach or mushrooms first to prevent soggy muffins.
- Whisk the eggs well for a lighter, fluffier texture.
- A silicone muffin pan makes the muffins easier to remove.
- Add shredded cheddar, feta, or mozzarella for extra flavor.
