Slow Cooker Taco Mac Casserole

Mike tried this recipe on September 12, 2021

This is simple comfort food with a twist – think a Southwestern take on beefy macaroni and cheese. It’s perfect for those nights when you want to make something hearty and full of flavor that everyone will enjoy. Serve it by itself or with tortilla chips, salsa, and even sour cream on the side. And using a slow cooker means not having to spend all afternoon in the kitchen.

I made one change from the original recipe in adding a can of Ro*Tel tomatoes and peppers for a little extra kick.

  1. In a large skillet, cook the ground beef over medium-high heat until browned, breaking into crumbles as it cooks. Drain off any excess fat.

  2. Prepare the elbow macaroni according to package directions, draining well after cooking.

  3. In a large bowl combine beef, macaroni, and all other ingredients. Mix well.

  4. Pour mixture into a 6-quart slow cooker that has been lightly sprayed with nonstick cooking spray.

  5. Cover and cook on Low for 3-4 hours, stirring occasionally.
