Best ways to enjoy it
This casserole is incredibly versatile. Serve it topped with fresh cilantro and a dollop of sour cream for an extra punch. It pairs wonderfully with a simple side salad or some crusty bread. For a fun twist, consider adding tortilla chips for a crunchy texture or even some sliced jalapeños if you enjoy a bit of heat!
Storage and reheating tips
Leftovers can be safely stored in an airtight container in the fridge for up to 4 days. To reheat, place your desired portion in a microwave-safe dish, covering it loosely to retain moisture, and heat until warmed through (about 2-3 minutes). Alternatively, it can be reheated on the stove over low heat, stirring occasionally. If you want to store it longer, this casserole freezes well for up to 3 months—just be sure to let it cool completely before transferring to a freezer-safe container.
Helpful cooking tips
For an added flavor kick, consider cooking the beef with some taco seasoning for an extra layer of spices. Make sure to adjust the salt if your seasoning contains sodium. Additionally, browning the meat before adding it to the slow cooker enhances the dish’s flavor, so don’t skip that step!
Creative twists
There are countless ways to personalize this casserole. Swap out black beans for kidney beans or use different vegetables, like bell peppers or carrots, according to your taste preferences. For added creaminess, you can mix in a cup of cream cheese before serving. If you’re a fan of spice, adding more chili powder or even a splash of hot sauce can give it the kick you crave.
