Slow Cooker Spaghetti sauce is slow-cooked and full of vegetables and herbs; perfect over any shape of pasta.
We love pasta night at our house. When we aren’t making this classic spaghetti sauce in our crock pot, we have Pesto Mozzarella Chicken and pasta or Cajun Chicken Fettuccine.

How long do I cook spaghetti sauce in the slow cooker?
- Place the lid on the slow cooker. Cook on LOW for 8 hours or on HIGH for 4 hours.
- Stir and serve on desired noodles. I use bucatini noodles, they are a larger noodle with a hollow in the center and goes great with slow cooker spaghetti sauce.
How do I make a thick spaghetti sauce?
A small can of tomato paste is what I use thicken this spaghetti sauce. Do not forget to add it or you will have a watery sauce.
Can I use Italian sausage instead of ground beef?
- You can substitute one pound of Italian Sausage for the ground beef in this recipe.
- Cut the salt in half for the recipe in half if you use Italian sausage.
Can I add frozen meatballs instead of ground beef?
Use a 2 lb. bag of frozen meatballs if desired in place of the groung beef.
Can I add uncooked noodles into the sauce in the slow cooker?
DO NOT add uncooked noodles to the slow cooker. The slow cooker doesn’t get hot enough, fast enough to properly cook noodles. The noodles will turn out mushy.
Can I make this vegetarian?
- Add soy crumbles to this recipe instead of ground beef if desired.
- Or add chopped carrots, celery and mushrooms.
Can I add red wine?
Add a half cup of red wine at the beginning of the recipe if you would like a red wine flavored sauce. I like to use red blend when I’m cooking (and for drinking).

How long do you cook the pasta before putting into the slow cooker? Love the recipes
The pasta should never be added to the pasta sauce in the crock pot.
One hour before you plan to serve dinner, fill a large pot with water, and bring to a boil on top of the stove. Turn off the heat and place a lid on the water. About 20 minutes before serving time, add olive oil to the water and bring to a boil.
Add the pasta to the boiling water and stir until the pasta is submerged in the water. If the water boils over, turn down the stove until the pasta is cooking, but not spilling on top of the stove.
Follow package directions for cooking the pasta. When the pasta is done, drain the water off and put the pasta back into the pot, add olive oil, and stir to coat the pasta. Cover the pasta with a lid until serving time.
