Crockpot Beef Barbacoa Burrito Casserole Step-by-step instructions

Before you start

Before starting, make sure the beef barbacoa is already cooked and shredded. If using store-bought, check that it's heated through when added. Cook the Spanish rice according to package instructions or use leftover rice.

Drain and rinse the pinto beans. Shred the cheese if not pre-shredded. Have the red enchilada sauce, corn, and all serving toppings ready. This recipe comes together quickly once the prep is done.

Instructions

Layer and Top with Cheese

1. 1Layer the Casserole
   In a 6-quart slow cooker, spread the shredded chipotle beef barbacoa evenly over the bottom. Top with the cooked Spanish rice, then the drained pinto beans, then the corn kernels. Pour the red enchilada sauce over the top, using a spoon to gently distribute it without stirring the layers.
   Look for The layers should be visible: beef on the bottom, then rice, beans, and corn, with sauce covering the top.
   Tip Do not stir the layers; the slow cooker will meld the flavors as it cooks.
2. 2Add the Cheese
   Sprinkle the shredded Oaxaca-cheddar blend evenly over the top of the casserole, covering the sauce completely. The cheese will melt and form a bubbling blanket as the casserole cooks.
   Look for The cheese should form an even layer over the sauce, with no gaps.
   Tip Shredding the cheese yourself helps it melt more smoothly.

The slow cooker should be filled with distinct layers: beef on the bottom, then rice, beans, corn, and a pour of red enchilada sauce.

The top should be completely covered with shredded cheese. The colors should be vibrant—dark beef, white rice, brown beans, yellow corn, and a red sauce with a white cheese cap.

Slow Cook and Melt

3. 3Slow Cook on Low
   Cover the slow cooker and cook on LOW for 3 hours, until the casserole is bubbling around the edges and the cheese is fully melted and slightly golden. The beef should be heated through and the rice tender. Let it rest for 3 minutes before slicing.
   Look for The casserole will be bubbling at the edges and the cheese will be melted and gooey.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resist lifting the lid during cooking; the heat escapes and extends cooking time.
4. 4Check the Temperature
   Use an instant-read thermometer to check that the beef reaches a safe internal temperature of 145°F (63°C). If not, continue cooking for another 15–30 minutes and check again. The casserole should be hot and bubbling throughout. Let it rest for 3 minutes before slicing.
   Look for The thermometer should read at least 145°F (63°C) in the center of the beef.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Insert the thermometer into the thickest part of the beef, avoiding the rice.

After three hours on low, the casserole should be bubbling at the edges and the cheese melted and slightly golden. The aroma will be smoky, spicy, and cheesy. The sauce should be absorbed partially by the rice, and the beef should be heated through. Check the temperature to ensure it reaches 145°F (63°C).

Serve with Toppings

5. 5Rest and Serve
   Turn off the slow cooker and let the casserole rest for 5 minutes. Scoop generous portions into wide bowls, then top with guacamole, sour cream crema, pico de gallo, fresh cilantro, and a lime wedge for squeezing.
   Look for The casserole should hold together when scooped, with layers visible.
   Tip Letting it rest helps the casserole set slightly for easier serving.

The casserole should be bubbling and the cheese golden. When scooped, it should hold its shape slightly, with visible layers. Toppings like guacamole, crema, pico de gallo, cilantro, and lime add freshness and color. The dish should look hearty and inviting, with steam rising.

Common mistakes

One common mistake is lifting the lid to check on the casserole during cooking. This releases heat and extends the cooking time. Another is over-stirring the layers, which can turn the casserole into a mushy mess.

Also, using pre-shredded cheese that contains anti-caking agents can affect melting; shredding your own is better. Finally, don't skip the resting time after cooking—it helps the casserole firm up slightly for cleaner servings.

How to tell it’s done

The casserole is done when it is bubbling around the edges and the cheese is fully melted and lightly golden. The internal temperature of the beef should read at least 145°F (63°C) on an instant-read thermometer.

The rice should be tender and have absorbed some of the sauce, and the casserole should hold together when scooped. Let it rest for 5 minutes before serving to allow the layers to set.
