Ingredients
Here’s what you need for about 24 Mini Quiche Muffins. I bolded the must-knows so you don’t miss them!

- 10 large eggs (room temperature for fluffiness)
- 1 cup whole milk (or half-and-half for extra creaminess)
- 1 cup shredded cheddar cheese
- ½ cup diced bell peppers (mix colors for fun)
- ½ cup chopped spinach (fresh or thawed frozen)
- ¼ cup sliced green onions
- 4 slices cooked bacon, crumbled (swap for ham or sausage)
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- Non-stick cooking spray or butter for greasing
Instructions
Ready for a mini version of all your favorite Egg Casserole Recipes? These muffins bake in just 20 minutes—perfect for a true Breakfast Casserole Make Ahead or even a Breakfast Casserole Overnight scenario. Let’s roll!
- Preheat your oven to 375°F (190°C). Grease a 24-cup muffin tin with non-stick spray or butter.
- Crack all 10 eggs into a large bowl. Pour in the milk and whisk until the mixture looks slightly frothy.
- Stir in the salt, pepper, and garlic powder. I love the subtle kick this seasoning trio adds.
- Fold in shredded cheddar, bell peppers, spinach, green onions, and bacon. Make sure you distribute ingredients evenly—nobody wants an all-pepper muffin 😉 .
- Divide the egg mixture evenly among the muffin cups. Fill each about ¾ full; the eggs will puff up beautifully.
- Bake for 18–20 minutes, or until the centers set and the tops turn lightly golden. Peek in at the 15-minute mark if you’re curious.
- Remove the tin from the oven. Let the quiches cool for 5 minutes—this step prevents them from sticking.
- Use a small knife to gently loosen the edges, then pop out the muffins with ease.
- Serve warm, or let them cool completely before transferring to an airtight container.
- Store in the fridge for up to 5 days, or freeze in a zip-lock bag for up to a month. Reheat in the microwave for 30–45 seconds.
Variations
If you love Tortilla Quiche Bake vibes or you want to play around with Omlet Breakfast Ideas, try these spins on the classic recipe:
- Mediterranean Muffins: Swap cheddar for feta, add chopped sun-dried tomatoes and kalamata olives. A little oregano takes it over the top.
- Veggie-Packed Bites: Double up on zucchini, mushrooms, and spinach. Perfect if you aim for a Healthy Breakfast Casserole without sacrificing taste.
- Spicy Sausage Kick: Replace bacon with spicy chorizo or jalapeño sausage. Add a dash of hot sauce to the egg mix—hold onto your taste buds!
Serving & Tips
These Mini Quiche Muffins shine at any meal. Pack them for lunch, toss them in a Breakfast Basket, or serve alongside fresh fruit and yogurt. For a cozy fall touch, sprinkle in nutmeg and warm cinnamon before baking—hello, seasonal comfort!
Storage hacks? Store leftovers in single-serve containers for a grab-and-go morning. You can also layer pieces of parchment paper between muffins in your freezer bag—no sticking, no fuss. If you fancy a bit of crunch, broil for 1–2 minutes after microwaving.

Final Thoughts
I still remember the first time I brought these muffins to a Brunch Potluck. They vanished in minutes—even my aunt, who swears by her giant Easy Tater Tot Casserole, came back for seconds. These bite-sized wonders prove that you don’t need a massive dish to wow a crowd. 😋
Give them a shot, and let me know how you customize yours. IMO, adding a handful of fresh herbs like chives or parsley before serving takes these over the edge.
