Crockpot Meat Sauce for Spaghetti

This is a great crockpot spaghetti sauce. It tastes like a great traditional meat sauce. I might even add a little cream next time I make it just to switch it up a little. I got this great recipe from Real Mom Kitchen (it's her "Slow Cooker Bolognese Sauce"). It made the house smell so good as it was cooking!

Crockpot Meat Sauce for Spaghetti

2 pounds ground beef (could use 1 1/2 lbs beef and 1/2 lb Italian sausage)
1 cup chopped onion
8 cloves garlic, minced
3, 14 oz cans diced tomatoes, drained (reserve tomato juices to thin sauce if necessary before serving)
2, 14 oz cans tomato sauce
2, 6 oz cans tomato paste
3 tablespoons sugar
2 tablespoons dried oregano
1 tablespoon dried basil
1 teaspoon salt
1/2 teaspoon pepper

Brown beef in a large skillet until browned. Transfer to crockpot and combine with other ingredients, mix well. Cover and cook on low for 8 hours (stirring occasionally through out the day). Add reserved tomato juices from diced tomatoes to thin sauce if desired. Serve over spaghetti or other pasta with grated parmesan cheese on individual servings. I saved half of the sauce and froze it for another dinner.
