A warm, comforting one-pot pasta dish loaded with lean ground beef, fresh veggies, and classic Italian flavors—perfect for busy days and picky eaters alike.
In a skillet over medium heat, brown the ground beef until fully cooked. Drain any excess fat.
Add the diced onion and minced garlic to the skillet and sauté until the onion is translucent.
Transfer the beef mixture to the slow cooker.
Add the diced bell pepper, sliced carrots, and sliced celery to the slow cooker.
Stir in the diced tomatoes, tomato paste, beef broth, oregano, basil, salt, and pepper.
Cover and cook on low for 6-7 hours or on high for 3-4 hours.
About 30 minutes before serving, add the broken spaghetti noodles to the slow cooker and stir well.
Cover and cook until the noodles are tender, about 25-30 minutes.
Serve hot, topped with grated Parmesan cheese.
Notes
For a low-carb version, substitute spaghetti with spiralized zucchini or shirataki noodles. You can also swap the ground beef for Italian sausage or ground turkey for a different twist. Add a dash of crushed red pepper flakes for a little heat.
