Slow Cooker Ground Beef Pasta is a fuss-free meal perfect for weeknight dinners. Savory ground beef combines with tender noodles in a rich, cheesy tomato sauce for a comfort food the whole family will be excited to sink their teeth into!
In a medium pan over medium-high heat, brown the ground beef for about 5 minutes. Drain the excess fat. Add half of the diced onions and sauté for 2-3 minutes or until they soften.
Add the minced garlic, and cook for an additional 20 seconds. Turn off the heat, and transfer the beef mixture to the slow cooker.
Cook the pasta to al dente according to the package instructions. Set aside.
Add the jar of marinara sauce, diced tomatoes, remaining onion, paprika, oregano, Italian seasoning, water, and salt to the slow cooker. Stir to combine the ingredients.
Cook the mixture on medium heat in the slow cooker for 4 hours. After 4 hours, add the cooked pasta, and the shredded Mozzarella cheese. Stir well to combine all the ingredients.
Continue to cook for 30 minutes or until the pasta is well combined and the cheese is melted. Sprinkle the shredded Parmesan cheese on top, and serve warm.
