Tex Mex Breakfast casserole

Breakfast casseroles are perfect for a cozy, weekend breakfast or brunch. They take a little time to put together and bake; but so very easy. This casserole has a Tex Mex element with spicy turkey sausage, peppers, onions, Mexican cheese, chili powder and cumin. But also eggs and potatoes so definitely meant for breakfast.

Much like my equally delicious broccoli frittata this recipe is a great way to use up leftover vegetables for the week.


Potato: The base of the casserole. Use either a microwaved potato or a leftover baked potato.

Turkey: Ground turkey, turkey sausage, or our favorite; Chorizo turkey sausage! This casserole could also be meatless.

Vegetables: About 1 1/2 cups of mixed chopped vegetables. Onions and peppers are perfect; a jalapeño if you like spicy. I like including zucchini. Spinach or other greens would work as well.

Spices: Chili powder and cumin for the great Tex Mex flavor. Cayenne pepper is great for extra heat.

Eggs: The essential savory breakfast casserole ingredient.

Half & Half: Just one Tablespoon provides some great richness.

Cheese: Eggs and cheese…..what more do you need? Use Mexican cheese, pepper jack cheese, cheddar cheese; whatever you like.

Toppings: Avocado, cilantro, lime and salsa are all delicious. Some fresh tomato would also be nice.


This casserole truly couldn’t be easier to put together. Start with chopping the potato into small bite-sized pieces and spread evenly in the bottom of your prepped 8×8 casserole dish.

Cook sausage and vegetables in a skillet until sausage is brown and vegetables are somewhat tender. Layer across potatoes.

Sprinkle with cheese then pour beaten eggs, half & half and black pepper mixture. Add salt if desired but consider the sausage and cheese does contribute a fair amount of salt.

Bake until eggs are slightly puffed and a knife comes out clean when inserted in the center.

This recipe yields four generous servings. Leftovers re-heat very well in the microwave. Breakfast on Saturday morning turns into an easy leftovers on Sunday!
