Ingredients
- 10 large eggs
- 1/4 cup whole milk
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 1/4 tsp garlic powder
- 1 cup baby spinach, chopped
- 1/2 cup diced red bell pepper
- 1/4 cup thinly sliced green onion
- 1/2 cup cooked crumbled bacon or diced ham
- 3/4 cup shredded sharp cheddar
- Cooking spray, for the pan
Instructions
- 1
Preheat oven to 350°F. Generously coat a 12-cup muffin tin with cooking spray — this is essential to prevent sticking.
- 2
In a large bowl, whisk the eggs, milk, salt, pepper, and garlic powder until completely smooth and pale yellow.
- 3
Divide the spinach, bell pepper, green onion, and bacon evenly between the 12 cups.
- 4
Pour the egg mixture over the fillings, filling each cup about 3/4 full. Top each with a pinch of shredded cheddar.
- 5
Bake 18–22 minutes, until the centers are puffed and a toothpick comes out clean. They will deflate slightly as they cool — that's normal.
- 6
Cool 5 minutes in the pan, then run a thin knife around each muffin to release. Serve warm or cool completely for meal prep.

Frequently Asked Questions
How long do breakfast egg muffins last in the fridge?+
Stored in an airtight container in the fridge, they stay fresh for up to 5 days — perfect for the full work week.
Can I freeze egg muffins?+
Yes — freeze on a sheet pan until solid, then transfer to a zip-top bag for up to 3 months. Reheat from frozen in the microwave for 60–90 seconds.
Why did my egg muffins stick to the pan?+
Egg proteins grip metal aggressively. Use silicone liners, parchment liners, or a heavy coat of cooking spray (yes, even nonstick pans need it).
What other fillings work well?+
Diced cooked sausage, sautéed mushrooms, roasted broccoli, sun-dried tomatoes, or feta cheese are all excellent. Just avoid raw watery veg like zucchini or tomato.
How do I reheat egg muffins?+
Microwave 30 seconds for refrigerated muffins or 60–90 seconds from frozen. A damp paper towel on top keeps them moist.
Can I make these dairy-free?+
Skip the cheese and swap milk for unsweetened almond or oat milk. They'll still puff up beautifully.
