Recipe Details

Low-Carb Crock Pot Taco Macaroni Casserole

- 2 14- oz cans palmini noodles drained and rinsed
- 1 medium onion diced
- 2 bell peppers chopped
- 2 cups sugar-free marinara sauce

- 3 cups shredded cheddar cheese divided
- 1 4- oz can diced green chilies
- 2 cloves garlic minced
- 1 cup beef broth
- Salt and pepper to taste
Instructions
- Brown the ground beef in a large skillet over medium heat, breaking it up into small, even pieces. Drain excess fat if desired.
- Transfer the browned beef to your crock pot. Trust me, don't skip the browning step – it adds so much flavor!
