- 8 eggs: Use large AA eggs for the best results.
- 1 small ciabatta, cut into cubes: Thick bread will make these eggs even more filling and thick.
- 2⁄3 cup chorizo, sliced: You can find chorizo by the sausage in the meat section of the grocery store.
- 1 1⁄4 cup shredded mozzarella: Buy pre-shredded, processed cheese or buy a block and shred it yourself with a food processor or hand grater for better results.
- 2⁄3 cup milk: Whole milk works best in this dish.
- 2 teaspoon grainy mustard: You can use dijon or whole-grain mustard here.
- salt and pepper: A little seasoning will bring out the other flavors.
- 1 medium white onion, chopped: Finely chop the onion so you won’t get big chunks of onion in your bite.

- olive oil: Olive oil will grease the muffin tin so the eggs won’t stick when you pull them out.

What other ingredients can I use in this casserole?
If you want to make these egg bites even more delicious and filling you can add some other ingredients. Try potatoes, hashbrowns, green beans, asparagus, spinach, kale, green onions, or garlic.
Can I use a different kind of meat?
If you can’t find chorizo or want to try a different kind of meat, there are some options you can use.
Try ground beef, bacon, or sausage instead of the spicy chorizo.
Can I make muffin egg casserole ahead of time?
It’s easy to make this dish overnight and then serve it in the morning. It may even help you have a good breakfast when you don’t need to worry about making it the same day. You can focus on getting yourself (or kids) ready instead.
How to store:
Store any leftover casserole in an airtight container in the refrigerator for up to five days. Reheat it in the microwave with 30-second increments until it’s hot all the way through.
To freeze the entire casserole, wrap it in aluminum foil and plastic wrap. Label it with what it is, how to cook, and the date. Labeling will help you remember later. Remember that if you cook it from frozen, it will take longer to cook in the oven without thawing first. Keep the foil on until the last 30 minutes of cooking so the top can brown.
Do I need to use a muffin tin to make this dish?
If you don’t have a muffin tin or would prefer to use a casserole dish, that’s perfectly fine. Remember the baking time will differ depending on the pan you use. Use a toothpick to test when the center is baked. The toothpick will come out clean when it’s ready.
Can I make muffin egg casserole in an instant pot?
Yes, you can make this casserole in an instant pot. Grease the bowl of the pressure cooker, pour the egg mixture in, and seal the lid. Cook for five minutes, carefully release the pressure, remove the lid, and serve immediately.
Is this casserole keto-friendly?
No, this egg muffin casserole recipe isn’t strictly keto, but you can easily remove the ciabatta bread to make it keto-friendly.
