Add the entire bag of meatballs to an 8 quart slow cooker.
Mix the taco seasoning and enchilada sauce in a bowl until combined.
Pour over the meatballs and stir until the balls are completely coated.
Cook on low for 4 hours stirring every so often.
Once done cooking, sprinkle the cheese all over top and place the lid on for 5 minutes until the cheese is melted. Serve and enjoy!
Notes
Spray the slow cooker with nonstick cooking spray or use a liner before. This makes cleanup so much easier!
Don't thaw the frozen meatballs. They cook from frozen just fine and thawing makes them mushy.
Stir every hour or so during cooking to keep the meatballs coated in sauce and prevent sticking. Set a timer so you don't forget!
Mix the taco seasoning and enchilada sauce together before pouring over meatballs. This distributes the seasoning so you don't have clumps in the sauce.
Add cheese only at the very end and let it melt with the lid on. Adding it earlier makes it separate and get oily.
Use an 8-quart slow cooker for best results. Smaller sizes work but the meatballs will be more crowded.
