Lazy Enchiladas Recipe: Easy Weeknight Casserole

Lazy enchiladas are a layered casserole of corn tortillas, seasoned ground beef, black beans, enchilada sauce, and melted cheese. Inspired by the flavors of Mexican enchiladas, this shortcut skips rolling each tortilla, so dinner comes together in one baking dish and is easy to portion at the table.

Ingredients

1 tablespoon (15 ml) neutral cooking oil, such as canola or avocado oil
1 medium yellow onion, finely diced, about 1 cup (150 g)
1 pound (450 g) lean ground beef, preferably 85% to 90% lean
2 garlic cloves, minced, about 2 teaspoons (6 g)
1 tablespoon (8 g) chili powder
1 teaspoon (2 g) ground cumin
½ teaspoon (1 g) smoked paprika
½ teaspoon (3 g) fine salt, plus more to taste
¼ teaspoon (0.5 g) ground black pepper
1 can (15 ounces/425 g) black beans, drained and rinsed, about 1½ cups (260 g)
2 cups (480 ml) red enchilada sauce, divided; use mild or medium to taste
12 corn tortillas, about 6 inches (15 cm) wide and 10½ ounces (300 g) total
2 cups (200 g) shredded Monterey Jack, cheddar, or a combination
2 tablespoons (12 g) sliced green onions, optional, for serving

Instructions

Heat the oven and prepare the dish. Set a rack in the center of the oven and heat it to 375°F (190°C). Lightly oil a 9-by-13-inch (23-by-33-cm) baking dish. Dice the onion, mince the garlic, drain and rinse the beans, and measure the spices and sauce. The oven can heat while you prepare the filling and assemble the casserole.
Cook the beef and aromatics. Heat the oil in a large skillet over medium heat. Add the onion and cook for about 3 minutes, stirring, until it begins to soften. Add the ground beef and break it into small pieces with a wooden spoon. Cook for about 6 minutes, stirring and breaking up any large clumps. Add the garlic, chili powder, cumin, smoked paprika, salt, and pepper; stir for 30 seconds, just until fragrant. Continue cooking until no pink remains and a food thermometer inserted into the beef reads 160°F (71°C), the USDA FSIS safe minimum temperature for ground meat.
Make the filling. Stir the rinsed black beans and 1 cup (240 ml) of the enchilada sauce into the skillet. Let the mixture bubble gently for 1 minute, then remove it from the heat. Taste a small spoonful and adjust the salt or pepper if needed. The filling should be moist but not soupy; the beans and tortillas will absorb some of the sauce as the casserole bakes.
Build the layers. Spread ½ cup (120 ml) of the remaining sauce across the bottom of the prepared dish. Arrange 4 tortillas over it, overlapping them as needed to cover most of the surface. Spoon half of the beef-and-bean mixture evenly over the tortillas, then scatter over ½ cup (50 g) of cheese. Repeat with 4 more tortillas, the rest of the filling, and another ½ cup (50 g) of cheese. Finish with the last 4 tortillas. Pour the remaining ½ cup (120 ml) sauce over the top and spread it toward the edges, then cover with the remaining 1 cup (100 g) cheese.
Bake and rest. Bake uncovered for 22 minutes, until the sauce bubbles around the edges and the cheese is melted. If the cheese is browning faster than the edges are bubbling, loosely cover the dish with foil for the rest of the bake. Set the casserole on a heat-safe surface and let it rest for 5 minutes before cutting; this brief rest helps the layers hold together when served.
Serve. Cut into 8 portions with a broad spatula. Add sliced green onions if you like, and bring extra enchilada sauce or salsa to the table. Use care when serving because the center can remain very hot after the dish comes out of the oven.

Tips

Keep the tortillas flexible. Corn tortillas can crack if they are very cold or dry. Warm them in a stack, wrapped in a clean damp paper towel, in the microwave for about 20 to 30 seconds before layering. They do not need to be cooked separately. If your tortillas are fresh and pliable, you can layer them straight from the package.
Choose the right sauce amount. This recipe uses 2 cups (480 ml) total. Some brands of sauce are thicker or saltier than others, so spread it evenly rather than pouring it in one spot. If your sauce is especially thick, stir 1 to 2 tablespoons (15 to 30 ml) of water into it; too much extra liquid can leave the bottom layer loose.
Use a thermometer for the beef. Color alone is not a reliable way to confirm that ground meat has reached a safe temperature. Check a few spots in the crumbled beef, especially any larger pieces. If you use ground turkey instead, cook it to 165°F (74°C), the USDA FSIS safe minimum for poultry.
Make clean portions. Let the casserole rest for the full 5 minutes and use a broad, sturdy spatula. The first serving may be less tidy than the next ones, but cutting smaller, neat squares while the dish is piping hot can make the layers slide apart.

Serving Suggestions

Serve the casserole as a filling main dish with a crisp green salad, shredded lettuce, or a simple cabbage slaw dressed with lime. Rice, seasoned or plain, is useful alongside if you want to stretch the meal, while charred corn or sautéed peppers make a colorful vegetable side. A spoonful of salsa, pico de gallo, or pickled jalapeños adds brightness and crunch to the soft, cheesy layers.

For toppings, set out chopped cilantro, sliced green onions, diced avocado, and sour cream or plain yogurt so each person can add what they like. Keep cold toppings off the casserole until serving rather than baking them into the dish. If serving a crowd, cut the casserole into portions in the pan and provide a serving spoon for any filling that shifts as it is lifted.

Variations

Make it vegetarian: Leave out the beef and use 2 additional cups (about 330 g) of drained beans, such as pinto beans, or combine beans with 1½ cups (225 g) of sautéed diced zucchini or bell pepper. Cook the vegetables until tender before adding the beans and sauce. The finished casserole will be softer and less rich than the beef version, but still substantial.

Swap the protein: Ground turkey or chicken works in place of beef; cook it to 165°F (74°C) using a thermometer. For cooked shredded chicken, stir in about 3 cups (400 g) and warm it in the skillet with the beans and sauce rather than browning it. A prepared rotisserie-style chicken can save time, but remove skin and bones and check that the meat is hot throughout before assembling.

Change the heat or cheese: Use green enchilada sauce for a tangier, usually milder flavor, or choose a hotter red sauce if you want more chile bite. Pepper Jack adds heat; Monterey Jack melts smoothly, while cheddar gives the topping a sharper taste. For a spicier filling, stir in 1 small diced jalapeño with the onion, removing the seeds for less heat.

Use flour tortillas if needed: Corn tortillas provide the familiar flavor and structure, but 8 small flour tortillas can be layered in their place. Flour tortillas soften more quickly and may make the casserole more tender, so avoid adding extra sauce. Large burrito-size tortillas are awkward in this pan; cut them to fit rather than folding thick sections into the layers.

Storage and Reheating

Refrigerate leftovers within 2 hours of baking. Transfer portions to a covered, shallow container, or cover the baking dish tightly once it has cooled enough to handle. The casserole keeps in the refrigerator for 3 to 4 days. Keep toppings such as avocado, lettuce, and sour cream separate and add them fresh when serving.

For a single portion, place it on a microwave-safe plate, cover loosely, and heat in short intervals, turning or checking between intervals so the middle heats evenly. For larger portions, cover an oven-safe dish with foil and warm at 350°F (175°C) until hot throughout. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer; heating time varies with portion size and whether the food starts cold.

You can freeze the casserole for up to 2 to 3 months for best quality. Cool it promptly, wrap individual portions or the whole dish securely, and label it with the date. Thaw overnight in the refrigerator for more even reheating, then heat to 165°F (74°C). Freezing may soften the tortillas and slightly change the texture, but the flavor remains suitable for an easy later meal. Do not leave cooked portions at room temperature for more than 2 hours.

Frequently Asked Questions

Do I need to cook the tortillas before layering?

No. The tortillas soften as they bake between the sauce and filling, so there is no need to fry or toast them first. If they feel stiff, briefly warm the stack so the tortillas bend without cracking. Avoid soaking them in sauce before assembling, which can make the finished casserole mushy.

Can I assemble lazy enchiladas ahead of time?

Yes. Assemble the layers, cover the dish, and refrigerate it for up to 24 hours before baking. For even baking, take the chilled dish out while the oven heats, but do not leave it at room temperature for longer than 2 hours. Because a cold casserole takes longer to heat through, allow extra baking time and check that it is bubbling in the center before serving.

Can I use store-bought enchilada sauce?

Yes. A jarred or canned red enchilada sauce is convenient and works well here. Taste it before seasoning the filling, since salt and chile heat vary by brand. If you cannot find enchilada sauce, use a smooth, seasoned red chile sauce as a substitute; salsa can work in a pinch, but it is usually chunkier and may make the layers wetter or taste less like classic enchilada sauce.

How can I tell when the casserole is done?

After about 22 minutes at 375°F (190°C), look for bubbling sauce at the edges and fully melted cheese. The beef should already have reached 160°F (71°C) in the skillet, so the bake mainly heats the layers together. If the dish is not bubbling after the stated time, continue baking in 3- to 5-minute increments, covering loosely with foil if the cheese is getting too dark.

Why did my enchilada casserole turn out watery?

Excess sauce, beans that were not drained, or vegetables that released liquid can all make the bottom soft. Drain and rinse the beans well, measure the sauce, and cook the beef mixture until it is moist rather than runny. Letting the baked casserole rest for 5 minutes also helps the tortillas absorb some of the liquid and makes portions easier to lift.
