How will this dish make your life easier?
You may have seen recipes for Mexican breakfast casserole. This is really similar. Isabel of Isabel Eats describes how chorizo is used in Mexican dishes, and describes the difference between Mexican chorizo and Spanish chorizo.
The chorizo I found at the store doesn't really fit into either category. it's a like a chorizo spiced regular sausage. The good thing about this recipe is that it's simple enough that any chorizo should work in it.
These freezer breakfast tacos, simple berry overnight oats, & peanut butter and banana overnight oats, and easy yogurt bowl are a couple of my other fave quick breakfast ideas.
What makes this breakfast casserole good?
Make ahead breakfasts are the perfect start for busy mornings. No cooking, no preparation, all you have to do is quickly heat up this chorizo breakfast casserole and get on with your day.
Take an hour to whip up this breakfast casserole, and then freeze in individual portions so you can grab and microwave it at home or at the office for a quick and nourishing breakfast.
How do I make this chorizo potato breakfast casserole?
Preheat oven to 350 degrees.
Start making your chorizo breakfast casserole by cutting 2 precooked chorizo sausage links into small pieces. I quartered each slice. You can cook them beforehand, but don't have to if they're precooked.
Brown uncooked chorizo, if you're using it.
Crack 6 eggs into a medium sized mixing bowl, add ½ cup milk, ½ teaspoon salt, ½ teaspoon pepper. Whisk until incorporated.
Add chopped chorizo sausage to eggs, then ½ cup frozen potatoes o'brien. These potatoes have chopped onions and peppers with them, so no need to add more red bell pepper. It makes for a delicious addition to your chorizo breakfast casserole.
See substitutions section for other suggested add-ins and toppings.
Transfer to a greased 8x8 inch baking dish. Top with ½ cup shredded cheese. I used a leftover cheese blend that was in my fridge. You can use cheddar, sharp cheddar, monterey jack, pepper jack, etc in your chorizo breakfast casserole.
Bake for 25-30 minutes, until it's cooked through. Enjoy your chorizo breakfast casserole slice immediately, refrigerate in an air-tight container, or freeze for later.
Serving suggestions: eat plain, with salsa/other toppings, or in a tortilla.
- Use precooked chorizo links or uncooked ones. Please cook uncooked sausage before adding it to the egg mixture.
- You can swap the potatoes o'brien for other hash browns or potatoes. I like these because they already have onions and peppers for added flavor. They're super easy!
- Use leftover vegetables in your fridge/kitchen, or buy pre-chopped vegetables for convenience.
- Slice into 4-6 pieces and freeze individual portions for quick breakfasts and lunches
- Other great add-ins: onion, bell peppers, spinach, canned diced tomatoes, cheese, zucchini, etc. Use what you have in the fridge.
- Great toppings: salsa, avocado, cilantro, tomatoes, guacamole, sour cream, or serve with a tortilla.
Chopped fruit would be a great side dish for a breakfast casserole, or a tortilla would be great with this chorizo casserole. Or even tortilla chips. There are a few delicious options.
Yes, it's a great way to a quick meal. Slice it up into individual servings, and then freeze on a baking sheet until frozen and place in a large freezer bag OR freeze in individual servings.
Place a serving of the casserole on a microwave safe plate and microwave for up to 60 seconds, or until warm. (Microwaving times may vary depending on individual microwave capabilities). Eat immediately.
How can I repurpose?
- Stuff your slice of chorizo breakfast casserole into a baguette or between a couple slices of bread for a quick lunch or dinner (yes, you can eat it outside of breakfast-time).
- Heat up a tortilla and wrap a slice of your casserole in it. Top with salsa if you'd like.
What can I make with leftover ingredients?
- Eggs: Egg Roll Up/Ugandan Rolex, Microwave Egg Bowl.
- Sausage: Cook sliced peppers and onions and serve them in a hoagie,
- Potatoes O'Brien: Substitute for hashbrowns in this Vegetarian Hash, sub for the potatoes in this Pan Seared Pork Chop recipe.

Breakfast casseroles are great for entertaining, too - I love to make them for brunch and serve it with a baked ham and mimosas or bloodys. This would be great for Easter!
right?! They're delicious & so easy. it'd be perfect for Easter morning
Great recipe! I also eat breakfast every day, usually about 1-2 hours after i get up. It's a must to get me energized (I mean, besides coffee). I'm not a fan of breakfast sausage, but feel like this would be great with some chicken sausage.
ya, that's what I used & it was great.
This is making my tummy grumble! I love a good breakfast casserole!
yay! me too! they're the best

I am not a big 'make breakfast in the morning' person, but I do get ravenous before lunch. So I've always had a love-hate relationship with breakfast. This is just so nutritious and delicious!

I admit to not being a breakfast eater. I am a late riser!
I get up at 7 and have the kids out of the door for school before 8.
I spend 30 minutes cleaning the house, then I sit down to breakfast and a cup of coffee. Usually catching up on emails.
But this casserole, it sounds delicious and I can see myself having it in the fridge to pick at, after a big brunch party!
Hi Claire, haha when you do get hungry in the morning, this could be a great option!
Abbey Sharp says
Breakfast in casserole form should ALWAYS be a thing. I would totally batch cook this for lunch too!
