So you want breakfast that tastes like a stack of breakfast tacos but with zero flipping and minimal effort? Same. This Breakfast Casserole With Tortillas is melty, savory, and stacked like a lasagna—only with eggs, cheese, chiles, and tortillas doing the heavy lifting. It’s brunch-y, crowd-friendly, and honestly…kind of foolproof.
Why This Recipe is Awesome
- It uses tortillas instead of bread, so you get soft, saucy layers with little crispy edges. It’s breakfast meets enchiladas and it absolutely slaps.
- You can build it mild or spicy, meaty or veggie, dairy-heavy or lighter—choose your own tasty adventure. It’s idiot-proof; even the “measure with vibes” crowd wins.
- Make it ahead, bake it fresh, slice it clean—this one loves meal prep and reheats like a dream for weekday mornings.
Ingredients You’ll Need
- Tortillas: 8–10 corn or flour (8-inch works best). Corn = classic and sturdy; flour = extra soft, cozy layers.
- Eggs: 8–10 large—go 10 if you want a taller, custardy bake.
- Dairy: 1½ cups milk or half-and-half—half-and-half gives luxe vibes; milk keeps it lighter.
- Cheese: 2–3 cups shredded (cheddar, Monterey Jack, or pepper jack). Freshly grated melts best.
- Meat (pick one or mix): 1 lb breakfast sausage, bacon, chorizo, or diced ham—cook and drain.
- Veggies: 1 small onion (diced), 1 bell pepper (diced), 1 can mild green chiles (drained), plus 1 cup corn or black beans if you like.
- Seasoning: 1 tsp kosher salt, 1/2 tsp black pepper, 1 tsp chili powder, 1/2 tsp cumin, 1/2 tsp garlic powder.
- Sauce layer (optional but delish): 1 cup salsa verde or red enchilada sauce mixed with 1/3 cup sour cream for a creamy swipe.
- Toppings: cilantro, green onions, avocado, hot sauce, lime wedges, more salsa.
Step-by-Step Instructions
- Prep and preheat
Heat the oven to 350°F. Grease a 9×13-inch baking dish. Tear or cut tortillas in halves or quarters for easier layering. Keep it casual; it’s rustic, not rocket science. - Cook the flavorful stuff
Brown sausage or chorizo in a skillet (or crisp up bacon), then drain. Sauté onion and bell pepper with a pinch of salt until softened, 3–5 minutes. Stir in green chiles and any add-ins like corn or beans. Taste and season. - Whisk the custard
In a big bowl, whisk eggs, milk/half-and-half, salt, pepper, chili powder, cumin, and garlic powder until smooth. No streaks. Aim for fluffy, not curdled later—this step matters. - Layer like a pro
- Thin swipe of the creamy sauce (if using) on the bottom.
- Single layer of tortillas (overlap to cover).
- Half the meat/veg mix.
- 1 cup cheese.
- Repeat tortillas, meat/veg, cheese.
- Final layer: tortillas, a little sauce, and remaining cheese. Even layers = even bake.
- Pour and settle
Pour the egg mixture evenly over the casserole. Tap the pan on the counter to release bubbles and help the eggs seep into the nooks. Let it sit 5 minutes to hydrate the tortillas. - Bake it
Cover loosely with foil and bake 30 minutes. Uncover and bake 10–20 more minutes until the center is set (no liquidy jiggle) and the top is golden. If it’s browning too fast, re-tent the foil. - Rest and finish
Let it rest 10–15 minutes for clean slices. Top with cilantro, green onions, and a squeeze of lime. Serve with salsa, crema or sour cream, and hot sauce. Boom—brunch glory.
Common Mistakes to Avoid
- Thinking you don’t need to preheat—rookie mistake. Cold oven = rubbery eggs and sad edges.
- Skipping the drain on meat and chiles. Extra liquid turns your casserole into a slip ’n slide.
- Going wild with watery veggies. Sauté mushrooms/spinach first so they don’t flood the party.
- Pouring and baking immediately. Let the tortillas soak a few minutes so layers hold. Patience = tidy slices.
- Overbaking until it’s dry. Pull it when the center barely jiggles—carryover heat finishes the set.
Alternatives & Substitutions
- Tortillas: Corn for sturdier layers and toasty flavor; flour if you like softer, “enchilada-ish” vibes. Gluten-free corn works great.
- Sauce: Salsa verde + sour cream is dreamy, but red enchilada sauce slaps too. Skip sauce entirely for a classic “taco bake” feel.
- Protein: Bacon + sausage + ham = meat lover’s heaven. Or go chorizo for smoky heat. Meatless? Add seasoned black beans and roasted sweet potatoes.
- Veggies: Try poblanos, jalapeño, zucchini, roasted mushrooms, or spinach. Roast or sauté to drive off moisture.
- Cheese: Monterey Jack for melt, cheddar for bite, pepper jack for kick, or a sprinkle of cotija after baking for salty flair.
- Lighter tweaks: Use half egg whites, reduced-fat cheese, and load up veg. You’ll still get that cozy slice moment.
FAQ
- Can I assemble this the night before?
Absolutely. Cover and chill up to 12 hours. Bake from cold and add 5–10 extra minutes. Watch for a fully set center. - Corn or flour tortillas—what’s better?
It’s a vibe thing. Corn holds structure and brings toasty flavor; flour turns pillowy. Both work. Use what you love. - How do I keep it from getting soggy?
Drain meats and chiles, sauté watery veg, don’t drown it in sauce, and let it rest after baking. Also, keep your foil loose, not steamy-tight. - Can I make it spicy without scaring brunch guests?
Use pepper jack and put hot salsa on the table. People can choose their own spice adventure. Everyone wins. - Can I freeze it?
Yes. Bake, cool completely, slice, and freeze portions. Reheat covered at 325°F until hot, then uncover to re-melt and crisp the top. - What if I don’t have enchilada sauce?
Use a layer of salsa mixed with a little sour cream or Greek yogurt. Or skip the sauce and add an extra 1/2 cup cheese—never a bad idea. - How do I know it’s done?
The top is golden, the edges puff a bit, and the middle doesn’t slosh. A knife inserted in the center should come out with moist but set curds.
Final Thoughts
