I browned a pound of ground beef and a pound of hot Italian sausage in 1 tbsp of olive oil.
I transferred it to the crockpot when it was crisp, then added a diced onion, 2 diced carrots, a diced stalk of celery, some salt and pepper. I cooked that until the onions were translucent:
To that I added 3 tbsp of tomato paste and 1 tbsp of minced garlic. That cooked for one minute, and then I transferred it to the crockpot:
Then I stirred in 2 cans of drained diced tomatoes, 3/4 cup of milk, and 3/4 cup of red wine.
That cooked for 6 hours on low, I cooked up some spaghetti, and served the sauce on top with some grated Parmesan. This recipe actually makes a double batch, so 1/2 of it is set aside to use later.
I thought this sauce was possibly the best spaghetti sauce I've ever had! My oldest daughter really liked it too. The younger one and DH didn't like the tomatoes, but they liked it other than that. Maybe next time I'll try it with crushed tomatoes instead of diced. It was a little spicy, but not too much for me. I actually thought it tasted like pizza.
