I use the Torino Italian Sausages sold at Costco. They are really amazing in this sauce.
Ingredients
3 Tablespoons olive oil
1 medium or large onion, diced
5 cloves garlic, crushed
4 – 28 oz cans crushed tomatoes – or one #10 can crushed tomatoes
½ cup carrot, finely grated
½ teaspoon red pepper flakes
1¾ Tablespoon dried Oregano
1¾ Tablespoon dried Basil
1¾ Tablespoon dried Parsley
2 Tablespoons brown bugar (or to taste, sometimes up to 3 Tablespoons)
Salt and Pepper to taste (roughly 1 T salt and ½ t pepper)
20 Torino mild Italian Sausages
Instructions
In a large stock pot, saute the diced onion in olive oil until translucent, 8-10 minutes. Add crushed garlic and saute slightly (be careful to not burn it).
Add the tomatoes, carrots, and all the seasonings (the rest of the ingredient list, minus the sausages). Stir together, and set the burner for a simmer.
In a skillet, brown the sausages on all sides. It is OK if they are still raw in the middle, we just want them browned to add flavor. Cut them in thirds (depending on their size) and add to the sauce.
Simmer the sauce for 2-4 hours, stirring every half hour or so, then taste and adjust salt, pepper, and brown sugar as needed.
