Ingredients Base Mixture:

8 large eggs
½ cup milk (optional, for fluffiness)
½ tsp salt
¼ tsp black pepper
¼ tsp garlic powder (optional)

Add-Ins (mix and match):

½ cup shredded cheese (cheddar, mozzarella, feta, etc.)
½ cup bell peppers, diced
¼ cup onion, finely chopped
½ cup cooked bacon, ham, or sausage, crumbled
¼ cup spinach or kale, chopped

Instructions

Preheat Oven: Preheat oven to 375°F (190°C). Grease a 12-cup muffin tin with cooking spray or butter.
Whisk Eggs: In a mixing bowl, whisk eggs and milk until smooth. Stir in salt, pepper, and garlic powder.
Prep Add-Ins: Chop veggies and meats. Make sure any meats are pre-cooked. Shred cheese.
Assemble: Evenly distribute the veggies, cheese, and meats into each muffin cup. Pour the egg mixture over the top, filling each cup about 3/4 full. Lightly stir with a fork.
Bake: Bake for 18-22 minutes or until the muffins are set and lightly golden. A toothpick should come out clean.
Cool & Store: Let muffins cool for 5 minutes before removing. Store in an airtight container in the fridge for up to 5 days, or freeze for up to 3 months.

Reheating Instructions

Microwave: 20-30 seconds from the fridge, or 45-60 seconds from frozen.
Oven: 350°F (175°C) for 5-10 minutes.
Air Fryer: 300°F (150°C) for 3-5 minutes.

Tips for Success

Grease your tin well: Even nonstick pans can stick—use cooking spray, butter, or silicone liners.
Avoid watery veggies: Drain or pre-cook ingredients like mushrooms or tomatoes.
Let them cool before removing: This helps the muffins set and come out cleanly.

Variations

Vegetarian: Load up on spinach, mushrooms, and cheese.
Spicy: Add jalapeños, pepper jack cheese, or hot sauce.
Dairy-Free: Skip the cheese or use a plant-based option.
Egg White Only: Use 10-12 egg whites instead of whole eggs.

Serving Ideas

Serve with avocado slices, fruit salad, toast, or Greek yogurt.
Great as a light lunch with a simple green salad.

Frequently Asked Questions Q: Why did my muffins deflate? A: Egg muffins naturally puff up in the oven and may shrink slightly as they cool. Let them rest a few minutes in the pan to help them set.

Q: Can I freeze these? A: Absolutely! Let them cool completely, freeze on a tray, then store in a zip-top bag. Reheat as needed.

Q: Can I bake these in a casserole dish? A: Yes! Pour the mixture into a greased 9×9 baking dish and bake at 375°F for 25-30 minutes, or until set.
