Prep & Cook Time
Prep Time: 10 minutes
Cook Time: 25 minutes
Total Time: 35 minutes
Servings: 12 muffins
Ingredients
- 10 large eggs
- ⅓ cup half and half ((79mL))
- 1 teaspoon salt
- ½ teaspoon ground black pepper
- 1 cup baby spinach (chopped (20g))
- ½ cup diced red bell pepper ((74g))
- ¼ cup diced onion ((37g))
- 4 oz feta (crumbled (112g))
Instructions
- Preheat your oven to 350°F (175°C). Generously grease a standard 12-cup muffin tin with non-stick cooking spray or butter.
- In a large mixing bowl, whisk together the eggs, half and half, salt, and black pepper until the mixture is smooth and well combined.
- Evenly distribute the chopped spinach, diced red bell pepper, diced onion, and crumbled feta cheese among the 12 muffin cups.
- Carefully pour the egg mixture into each muffin cup, filling them about ¾ of the way full. Gently stir with a fork to ensure the fillings are evenly distributed in the egg mixture.
- Bake for 20-25 minutes, or until the egg muffins are fully set, puffed, and the tops are lightly golden. A toothpick inserted into the center should come out clean.
- Allow the muffins to cool in the pan for 5 minutes before gently running a knife around the edges to loosen and remove them. Serve warm.
Variations
- Make it a Melt: After baking, top each muffin with a small sprinkle of extra cheese and broil for 1-2 minutes until melted and bubbly.
- Crustless Quiche Style: Pour the entire mixture into a greased 9-inch pie dish and bake for 30-35 minutes until set for an easy slice-and-serve option.
- Mini Bites: Use a 24-cup mini muffin tin for perfect party or kid-friendly appetizers; reduce the baking time to 12-15 minutes.
- Spice It Up: Add a pinch of red pepper flakes, smoked paprika, or a dash of hot sauce directly to the egg mixture before baking.
Tips for Success
- Chop all your vegetables into a small, uniform dice to ensure they cook evenly and distribute well in each muffin cup.
- Don’t overfill the muffin cups. Leaving about ¼ space at the top prevents messy overflow in the oven as the eggs puff up.
- For easy cleanup, consider using silicone muffin liners, which also make removing the baked muffins effortless.
- Let the muffins rest in the pan for 5 minutes after baking. This allows them to firm up and makes them much easier to remove intact.
Storage & Reheating
Store cooled egg muffins in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze them on a baking sheet before transferring to a freezer bag for up to 3 months. Reheat in the microwave for 30-60 seconds until hot, or in a toaster oven/regular oven at 350°F for about 10 minutes to restore a crispy exterior.
FAQ
Can I make these egg muffins ahead of time?
Absolutely! They are designed for meal prep. Simply bake, cool, store, and reheat throughout the week.
Can I use milk instead of half and half?
Yes, you can substitute an equal amount of whole milk, but the half and half gives a richer texture and creamier result.
Why did my egg muffins deflate?
Some deflation is normal as they cool, similar to a soufflé. Ensure they are fully cooked through before removing them from the oven to minimize this.
Can I bake these in a silicone muffin pan?
Yes, a silicone pan works wonderfully. You may not even need to grease it, and the muffins pop out very easily.
My muffins stuck to the pan. How can I prevent this?
Grease your tin *very* well, including the top surface. Non-stick spray with flour (like baking spray) is highly effective for this recipe.
Are these egg muffins freezer-friendly?
Yes, they freeze exceptionally well. Thaw overnight in the fridge or reheat from frozen in the microwave, adding extra time.
