Before You Begin
Prepare your slow cooker and ingredients as needed. Cooking times and results may vary depending on your equipment and ingredients.
Cook ground beef in a skillet over medium heat until no pink remains and internal temperature reaches 160°F (71°C). Drain excess fat. Stir in taco seasoning, chili powder, and cumin.
Lightly spray the slow cooker insert.
Add cooked beef, uncooked pasta, diced tomatoes with juice, broth, salsa, and 1 cup cheese in layers. Do not stir.
Cover and cook on LOW for about 2½ hours or until pasta is tender. Avoid lifting lid during cooking.
Stir gently to combine. Add remaining cheese and cover for 5–10 minutes until melted.
Let rest 5 minutes before serving to allow sauce to thicken and temperature to stabilize.
