How to Make Easy Mexican Casserole in a Slow Cooker
To a large skillet, add the ground beef and diced onion and cook over medium-high heat. Brown the meat until it is no longer pink.
Add the cooked meat and onion to the slow cooker. Then, add the enchilada sauce, undrained diced tomatoes, drained black beans, corn, bell peppers, uncooked quinoa, chili powder, cumin, garlic powder, and water.
Stir to combine making sure to mix everything together.
Place the lid on the slow cooker and cook until the quinoa is tender. You can choose whether you cook it on low or high, which of course will determine how long you cook it.
Remove the lid and add half of the shredded Mexican cheese and stir to combine. Then you’ll sprinkle the rest on top and close the lid, allowing the cheese to melt.
Serve with optional toppings like cilantro, sour cream or yogurt, avocado, and green onions. In fact, have everything set out in bowls around the table and everyone can choose their own!
Tips and Variations
- Use turkey instead of ground beef for a red meat substitution.
- To prep ahead, the night before brown the meat and dice the onions and peppers and be ready to dump in the crockpot the next day. Store in the fridge until you’re ready to use them.
- Make this dish in an Instant Pot on High Pressure/Manual for 30 minutes.
- Swap black beans for pinto beans, or use what you have in your pantry.
- For a vegetarian version of this Mexican Casserole, omit the meat and double the black beans. Mushrooms would also add a nice hearty texture.
- No need to rinse the quinoa as you would rice. Typically quinoa comes pre-rinsed.
How To Store It
If you’re lucky enough to have leftovers, it may be even better the next day! Keep in the fridge for up to 4 days in an airtight container or in the freezer for up to 1 month.
How to Reheat it
Reheat in the microwave or place in a baking dish to warm in the oven at 300 degrees until heated through.
