These mini crustless quiche, sometimes called egg muffins, are one of my favorite make-ahead breakfast recipes when life gets busy. They bake right in a muffin pan and are filled with eggs, cheese, sausage, and veggies for a simple, satisfying breakfast.

If mornings around your house look anything like they do here on the farm, you know breakfast sometimes has to happen fast.

The best part? You can mix and match whatever fillings you have in the fridge.

Ingredients

You only need a handful of simple ingredients.

Eggs, milk, cheese, sausage and veggies to make mini crustless quiche in muffin cups.

Cooked breakfast sausage: adds flavor and protein. I used browned and crumbled pork sausage but turkey sausage works well.
Cheddar cheese: I've found sharp cheddar works best
Baby spinach: for some color and nutrients
Bell peppers: any color works here - pick your favorite
Eggs - serve as the mini quiche base
Whole milk - the richness of this milk makes the texture creamy. You can also use half and half or 2% milk. I don't recommend using skim milk.
Salt and pepper

Tip: Pre-cooking the sausage keeps the egg muffins from getting greasy.

How to Prevent Egg Muffins From Sticking

Eggs love to stick to muffin pans. Make sure to spray the pan well with nonstick spray or use silicone liners. Let the egg muffins cool for a few minutes before removing so they release more easily.

Tips for the Best Egg Muffins

Let them cool briefly before removing

Don’t overfill! The eggs expand as they bake and will shrink as they cool.

Grease the pan well - eggs love to stick

Chop vegetables small so they cook more evenly
