Ingredients
- Ground beef
- Spaghetti sauce: use your favorite sauce or make a homemade spaghetti sauce.
- Pasta: spaghetti, rotinini, penne, etc. Any shape pasta works.
How To Make Slow Cooker Spaghetti and Meat Sauce
- Add the ground beef, sauce and 3 cups of water to the slow cooker.
- Set to low for 6-8 hours or high for 3-4 hours.
- With 20 minutes left, add the pasta and stir to make sure it's covered in the liquid. Cover and cook until pasta is soft, adding more water if needed.
- Serve with some parmesan cheese sprinkled on top and enjoy!
Kristina's Tips
- The sauce will be watery in the beginning because of the extra water added. This is okay because the pasta will absorb it later on. Thinning out the tomato sauce early on also keeps it from burning. You may also need to add more than 3 cups of broth.
- Throw in some chopped vegetables to make it heartier.
- Use beef broth instead of water or add an Italian seasoning blend to make it even more flavorful.

Tested Variations
- Use a different protein: Italian sausage, ground chicken and turkey are just as great as ground beef. They'll both make the recipe a little leaner but won't change the taste significantly.
- Vegetable add-ins: I've added diced carrots, peas and chopped spinach to the sauce. I like trying to hide the veggies from my kids who refuse vegetables as side dishes.
How To Store and Reheat
Fridge: store in a covered container for up to 5 days.
Freezer: you can store this is the freezer for up to 6 months but the pasta will become a lot softer. When you reheat it the texture may not be as enjoyable as it was when you ate it fresh.
Reheat: use the microwave to warm and if frozen, thaw in the fridge overnight or use the defrost setting on your microwave.
Frequently Asked Questions
Yes, Italian sausage, ground turkey, ground chicken and diced chicken all work.
Yes! That's what's convenient about this recipe. You don't need to take the extra step of cooking the pasta before adding it. You can if you'd like but don't use the 2 cups of water. Just boil the pasta on the stove and add it to the sauce when it's finished cooking.
