Ingredients & Quantities
The Base Egg Mixture:
- 10 large Eggs
- 1/4 cup Milk (dairy or unsweetened almond milk)
- 1/2 teaspoon Salt
- 1/4 teaspoon Black Pepper
- 1/2 teaspoon Garlic Powder
Flavor mix-ins (Choose your favorites or mix and match!):
- Spinach & Feta: 1 cup chopped fresh spinach + 1/2 cup crumbled feta cheese.
- Bacon & Cheddar: 1/2 cup cooked, crumbled bacon + 1/2 cup shredded cheddar cheese.
- Veggie Deluxe: 1/2 cup finely diced bell peppers + 1/4 cup finely diced onion + 1/4 cup chopped mushrooms.

Step-by-Step Instructions
- Preheat & Prep Tin: Preheat your oven to 350°F (175°C). This step is crucial: Liberally grease a 12-cup muffin tin with non-stick cooking spray or brush with oil. Pro Tip: Silicone muffin liners work amazingly well here and guarantee no sticking!
- Whisk the Base: In a large mixing bowl or a large glass measuring cup (for easy pouring), whisk together the eggs, milk, salt, pepper, and garlic powder until fully combined and slightly frothy.
- Add Fillings First: Distribute your chosen mix-ins (veggies, cheese, meat) evenly among the 12 muffin cups. Fill them about 1/4 of the way full with solid ingredients.
- Pour Eggs: Pour the egg mixture over the fillings in each cup, filling them about 3/4 of the way to the top. Do not overfill, as they puff up while baking! Give each cup a gentle stir with a fork to distribute the ingredients.
- Bake: Bake for 20–23 minutes. They are done when the centers are set and no longer jiggle, and the tops are slightly golden. They will look very puffy in the oven but will deflate slightly as they cool.
- Cool & Remove: Let them cool in the pan for 5 minutes before running a butter knife around the edges to pop them out.
Storage & Reheating (The Meal Prep Magic)
- Fridge: Let them cool completely, then store in an airtight container in the refrigerator for up to 5 days.
- Freezer: Wrap individually in plastic wrap and store in a freezer bag for up to 2 months.
- Reheating: From refrigerated, microwave on high for 30–45 seconds. From frozen, microwave for 60–90 seconds until warmed through.

Frequently Asked Questions
Why are my egg muffins spongy?
This usually happens if they are overcooked at too high a temperature. Stick to 350°F and check them right at the 20-minute mark.
Why are they watery at the bottom?
Vegetables with high water content (like zucchini, mushrooms, or frozen spinach) release water when cooked. To prevent soggy bottoms, quickly sauté watery vegetables and squeeze out excess moisture before adding them to the muffin cups.
Can I make these using only egg whites?
Yes! Substitute the 10 whole eggs for about 2 cups of liquid egg whites for a lower-calorie, lower-fat version.
