Not your everyday casserole
A typical breakfast casserole will have the basics – eggs, cheese, meat. We’ve totally upped the ante here with some incredible Mexican flavors and some crusty bread to bind the whole thing together. It’s not your mama’s eggs, that’s for sure. We are definitely bringing the heat in the form of spicy breakfast sausage and cayenne pepper!
How to Make a Spicy Mexican Breakfast Casserole
- Start by preheating your oven to 350 degrees. It will only take about 10 minutes to whip up the casserole so make sure you do this first. Grab a 1 1/2-2-auart baking dish and grease it with nonstick cooking spray or butter.
- Saute some onions with butter in a large skillet, then add some spicy breakfast sausage and cook thoroughly. Set aside.
- Tear or cut about a half of a loaf of french bread into bite sized chunks. You should get about 6 cups. Day old bread works best here, just leave it out overnight and it will be perfect. It will hold it’s shape much better as it absorbs the eggs.
- Arrange the bread in the bottom of your casserole dish, then top with the sausage and onion mixture. Whisk together eggs, cheese, spices and seasonings, then pour over the sausage.
- Bake in the preheated oven for about 20 minutes or until the eggs are fully set in the center. To make sure they’re done, use an instant read digital thermometer inserted into the center of the eggs. It should register 160 degrees.
Serving Suggestions
Serve this Mexican Breakfast Casserole for breakfast or even dinner with your favorite sides. Top with things like sour cream, salsa, cilantro, avocado and green onions.
What to do with Leftovers
Store leftovers covered in the fridge for up to 4-5 days. It’s great for meal planning! Reheat at 50% power in the microwave. I like to wrap slices in a damp paper towel to keep it from drying out.
Tips for Success
Just a few tips on this easy recipe:
- Breakfast casseroles are great make-ahead recipes! Prepare this casserole the night before, cover it and keep in the fridge to bake in the morning.
- Be sure to grease your baking dish really well. I forgot once and I had baked egg stuck to my dish! I felt so silly for forgetting, especially when I had to scrub it off later! So be sure to using some sort of cooking spray or butter to grease your dish.
- Second, feel free to add other things to this casserole. This is a great base recipe, but I could have added bell pepper or jalapenos or avocados on top. Add your favorite spice to give it a kick or don’t use any. It’s all up to you!
