This recipe couldn’t be any easier since your slow cooker pretty much does all the work.  There’s no need to even brown the beef.  Just add all of the ingredients to your slow cooker then set it and forget it.  Our sauce is a great base that’s enhanced by beef, wine and milk for a rich, savory, slightly creamy sauce.  Served over pasta with grated cheese it’s the ultimate comfort food.


cost per recipe: $17.62

  • 2 pounds 85% lean ground beef
  • 1 large onion, diced (about 1 cup)
  • 3 cloves garlic, minced or 1/2 teaspoon garlic powder
  • 1 cup milk
  • 1/2 cup dry red wine (optional)
  • 1 jar (45 ounces) or two jars (24-ounces each) Prego® Traditional Italian Sauce
  • 16 ounces uncooked spaghetti (cook according to package directions during last 30 minutes of slow cooker time)


  • Tips

    • Time-Saving Tip: You may also cook this recipe on HIGH for 4 to 5 hours.
    • Recipe Note: Reserve some of the cooking water from the spaghetti.  You can use it to adjust the consistency of the finished sauce, if you like.
    • Ingredient Note: If your market doesn't carry the 45-ounce jar of sauce, you can use two 24-ounce jars instead.
  • Step 1

    Place the beef (yes, it goes in uncooked!) into a 6-quart slow cooker.  Break up the beef with a fork and season with salt and pepper.

  • Step 2

    Stir in the onion, garlic, milk, wine, if desired, and sauce.

  • Step 3

    Cover and cook on LOW for 7 to 8 hours.  Spoon off any fat.  Stir the beef mixture, breaking up any large pieces of beef.  Season to taste with salt and pepper.  Serve with the hot cooked spaghetti and grated Parmesan cheese, if desired.

    I used ground turkey and Italian sausage instead of ground beef, I also cooked the meat before putting in the crock pot. I used all the other ingredients on the recipe and added about a teaspoon of mrs dash Italian seasoning and a can of diced tomatoes. This recipe is very tasty and I was able to freeze 4 containers.

    Campbellskitchen is one of my go to websites for dinner recipes! I am always looking for something different to serve my family. This is different than the traditional spaghetti sauce with meatballs recipe I make when we get the craving for spaghetti.. which is good but very time consuming. I have also tried baked spaghetti with cream cheese in the sauce. I'm glad I tried this recipe because it's prepared in a fraction of the time of either of the latter recipes. And I happen to like the bacon. I think it added a different dimension of meaty flavor and texture. Cooking the bacon was the most time consuming part of the preparation but well worth it. I liked throwing everything in the crockpot and not worrying about it. I found myself dipping French bread in it as I was putting the leftovers away! Delicious.

    This was an excellent recipe. I made a few changes to it. I added red pepper flakes to give the sauce a little more "oomph". I didn't have a slow cooker available, so I simmered everything in the skillet for half an hour.

    It was delicious. I would definitely make it again. I wouldn't add bacon next time though. I asked my husband if he tasted the bacon and he didn't even notice there was any. I hadn't tasted it either. While I love bacon, if I can get away without adding extra ingredients in a dish, I try to do that.

  • Very good spaghetti sauce

    This recipe was pretty easy to make and tasted really good. I made it as written except I used pre-cooked bacon to make it even easier. I served it with spaghetti squash and will definitely make it again.

    A little prep beforehand, and you have a delicious & nutritious meal that freezes well too! I used half extra-lean beef and half ground turkey Italian sausage, garden combination pasta sauce, and about a half cup red wine (pinot noir) in addition to a small can of spicy V-8 for added flavor. Turned out amazing!
