Ingredient Spotlight

small corn tortillas

Corn tortillas are thin flatbreads made from masa (nixtamalized corn dough) and are a staple of Mexican cuisine; they have a pronounced corn aroma and a slightly chewy, grainy texture compared with flour tortillas. They’re sold fresh or packaged in the Mexican/Latin aisle and at tortillerías; if you can’t find them, small flour tortillas or homemade tortillas made from masa harina (Masa Harina + water) are the closest substitutes, though the flavor and texture will differ.

Ingredient Spotlight

red enchilada sauce

Red enchilada sauce is a Mexican sauce typically made from rehydrated dried chiles (often guajillo or ancho) with garlic, cumin, oregano and tomato; it’s tangy, mildly smoky, and can range from mild to moderately spicy. You’ll find it canned or bottled in the Latin aisle or Mexican markets; a good substitute is a homemade puree of rehydrated guajillo/ancho chiles, tomato paste, garlic and cumin or a store-bought red salsa cooked down and seasoned to taste.

Ingredient Spotlight

shredded Mexican-blend cheese

Mexican-blend cheese is a pre-shredded mix (commonly cheddar, Monterey Jack, asadero, and/or queso quesadilla) formulated to melt well and suit Mexican dishes. It’s found in the refrigerated cheese section of most supermarkets; if unavailable, substitute with a 50/50 mix of shredded Monterey Jack and mild cheddar (freshly shredded from blocks for best melting and no anti-caking agents).

Jake's note

"This casserole shines at casual brunches and is excellent for prepping ahead—slice and refrigerate or freeze portions for quick reheating. Home cooks will love how it transforms simple breakfast ingredients into a crowd-pleasing layered bake."

Breakfast Enchilada Casserole

This Breakfast Enchilada Casserole turns the idea of a messy skillet scramble into a tidy, sliceable brunch centerpiece. Layers of torn corn tortillas soak up a bright red enchilada sauce while a savory mix of well-browned breakfast sausage, sautéed onions and red pepper, and a custardy egg-milk custard knit everything together. The contrast—soft, saucy pockets under a molten, slightly crisped cheese top—is what makes this version sing: the corn tortillas give a subtle grainy texture and corn flavor that stands up to the assertive sausage and chili-spiced eggs.

It’s a workhorse recipe for weekends and make-ahead mornings alike: assemble the night before to let the tortillas hydrate evenly, or portion and freeze for weekday reheats. Small technique choices—torn tortillas to avoid rigid layers, pre-cooking and draining fatty components, and a gentle whisked egg pour—keep it from becoming dense or greasy. Serve it with bright accoutrements (lime, cilantro, pickled onions) and it becomes as festive as it is practical, feeding a crowd or simplifying weekday breakfasts with little compromise on flavor.

Instructions

Cook the sausage and vegetables

Preheat the oven to 375°F (190°C). In a large skillet over medium heat, add the ground breakfast sausage and break it up with a spatula; cook until mostly browned, about 6–8 minutes. Add the diced onion and red bell pepper to the pan and sauté with the sausage until the vegetables are softened and the sausage is cooked through, another 4–5 minutes. Drain any excess fat if desired, then remove from heat and set aside.

For this step

1 lbground breakfast sausage
1 itemmedium yellow onion, finely diced
1 itemred bell pepper, seeded and diced

Whisk the eggs

In a large bowl, whisk together the eggs, milk, and chili powder until smooth and slightly frothy; season to taste with salt and pepper. This egg mixture will soak into the tortillas and bind the layers together for a custard-like texture when baked.

For this step

8 itemlarge eggs
1 cupwhole milk
1 tspchili powder

Assemble the casserole

Spread about 1/2 cup of enchilada sauce in the bottom of a 9x13-inch (23x33 cm) baking dish. Layer 2–3 corn tortillas (torn to fit) over the sauce, then spoon one-third of the sausage-vegetable mixture over the tortillas. Repeat layers (tortillas, sauce, sausage) once more, then arrange the remaining tortillas in the dish. Pour the egg mixture evenly over the assembled layers and press gently so the eggs distribute. Pour the remaining enchilada sauce over the top and scatter the shredded cheese evenly across the casserole.

For this step

8 itemsmall corn tortillas
2 cupsred enchilada sauce
2 cupsshredded Mexican-blend cheese

Bake until set

Bake in the preheated oven for 30–35 minutes, or until the eggs are set in the center and the cheese is melted and lightly golden. A knife inserted into the center should come out mostly clean when done. If the top browns too quickly, tent loosely with foil for the last 10–15 minutes.

Rest, serve, and store

Allow the casserole to rest 10 minutes before slicing to help it hold its shape; garnish with sliced green onions, cilantro, sour cream or avocado if desired. Refrigerate leftovers in an airtight container for up to 4 days, or freeze portions for up to 2 months—reheat in the oven or microwave until warmed through.

Tips from the kitchen

Brown the sausage well

Cook the sausage until it's deeply browned so you get rich caramelized flavor and less residual fat in the casserole.

Sauté vegetables first

Cook onions and peppers until softened and some moisture has evaporated—this prevents a watery bake and concentrates their sweetness.

Tear tortillas to fit

Tearing rather than neatly folding corn tortillas helps them conform to the dish and soak the egg-enchilada liquid evenly.

Press eggs into layers

After pouring the egg mixture, press gently so it distributes into gaps; this ensures an even custard rather than pools on top.

Avoid over-browning top

If the cheese is darkening too fast, tent loosely with foil for the last 10–15 minutes so the interior cooks without burning the surface.

Variations & substitutions

Vegetarian black bean

Swap the sausage for a spiced black bean and corn mixture (season with cumin and smoked paprika) and add sliced zucchini for extra body.

Chicken enchilada

Use shredded rotisserie chicken tossed with a little enchilada sauce in place of sausage for a leaner, milder-flavored casserole.

Dairy-free version

Use an unsweetened plant milk (soy or oat) in the egg mix and top with a vegan shreddable cheese; a sprinkle of nutritional yeast adds savory depth.

Spicy chorizo twist

Replace breakfast sausage with Mexican chorizo for a smokier, spicier profile; reduce added chili powder accordingly to balance heat.

Storage & make-ahead

Cool the casserole completely before refrigerating in an airtight container; it will keep well for up to 4 days. For longer storage, slice into portions and freeze wrapped tightly for up to 2 months. Reheat slices in a 350°F oven for 12–20 minutes or microwave single portions covered with a damp paper towel for 90–120 seconds until warmed through.

What to serve with it

Garnish slices with sliced green onion, chopped cilantro, a dollop of sour cream or crema, and a few avocado slices or pickled red onions to cut the richness. Serve alongside a crisp green salad or roasted breakfast potatoes, and offer lime wedges and hot sauce at the table; pair with bright coffee, a sparkling citrus mocktail, or a light margarita for brunch.

Frequently asked questions

Can I use flour tortillas instead of corn?

Yes—flour tortillas will yield a softer, less textured bite and absorb slightly less sauce, so you may want to tear larger pieces or use one extra tortilla layer for structure.

Can I assemble this the night before?

Absolutely; assemble, cover, and refrigerate up to 24 hours before baking. Bring it closer to room temperature for 20–30 minutes before baking so it cooks more evenly and the center sets in the allotted time.

How do I prevent the casserole from becoming soggy?

Drain excess fat after browning the sausage, cook vegetables until some moisture has evaporated, and avoid overly wet enchilada sauce—slightly thick sauce hydrates tortillas without turning them mushy.

Is there a way to make this lower in fat?

Use lean ground turkey or chicken sausage and substitute skim or low-fat milk for whole milk; you can also reduce the cheese to 1 cup or choose a lower-fat melting cheese.

How can I tell when it's done?

The center should be set and a knife inserted into the middle should come out mostly clean; the internal temperature of the custard should be about 160°F for safe eggs and a firm texture.
