Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 8 hours
• Total Time: 8 hours 20 minutes
• Servings: 12
• Yield: About 10 cups
• Dietary Type: Gluten-Free (check sausage ingredients)

Ingredients

• 1 tablespoon olive oil
• 1 large sweet onion, chopped
• ½ cup celery, chopped
• ½ cup carrot, chopped
• 1 lb Italian turkey sausage, casing removed
• 1 lb lean ground beef (90/10)
• 1 tablespoon Italian seasoning
• 4-6 garlic cloves, minced
• 1 (29 ounce) can crushed tomatoes
• 1 (6 ounce) can tomato paste
• 1 (29 ounce) can Italian-style diced tomatoes
• 1 tablespoon dried basil
• 1 teaspoon dried oregano
• 1 tablespoon sugar (optional)

Equipment Needed

• Large Skillet
• Slow Cooker (6-quart or larger)

Instructions

1. Heat the olive oil in a large skillet over medium heat.
2. Add the chopped onion, celery, and carrot to the skillet. Cook and stir until the onion becomes translucent and softened, about 5-7 minutes. This step, called “soffritto,” builds a deep flavor base for the sauce.
3. Add the Italian turkey sausage (with the casing removed) and the lean ground beef to the skillet.
4. Cook and stir, breaking up the meat with a spoon, until the meat is browned. This typically takes about 10 minutes. Be sure to drain off any excess grease to keep the sauce healthier.
5. Add the minced garlic and Italian seasoning to the skillet. Cook for about 1 minute, stirring constantly, until the garlic is fragrant. This prevents the garlic from burning and becoming bitter.
6. Transfer the cooked meat and vegetable mixture to the slow cooker.
7. Stir in the crushed tomatoes, tomato paste, and diced tomatoes. Ensure everything is well combined. Using good quality tomatoes, like Cento brand, will make a difference in the final flavor.
8. Add the dried basil and dried oregano.
9. Cook on low for about 8 hours. Resist the urge to open the slow cooker frequently, as this releases heat and can increase the cooking time.
10. About 15 minutes before serving, taste the sauce and decide if you want to add the sugar. The sugar helps to balance the acidity of the tomatoes, but it’s optional depending on your taste and the sweetness of the tomatoes used. Stir the sugar in if needed.

Expert Tips & Tricks

• Browning is Key: Don’t skip browning the meat and vegetables in the skillet before adding them to the slow cooker. This step develops a deeper, richer flavor that you can’t achieve by simply throwing everything into the slow cooker raw.
• Spice it Up: For a little heat, add a pinch of red pepper flakes to the sauce along with the other spices.
• Herbs Matter: While dried herbs work well in a slow cooker sauce, fresh herbs added in the last hour of cooking will brighten the flavor significantly. Consider adding a handful of fresh basil or parsley at the end.
• Deglaze for Extra Flavor: After browning the meat and vegetables, deglaze the skillet with a splash of red wine or beef broth before transferring everything to the slow cooker. This will loosen any browned bits stuck to the bottom of the pan and add another layer of flavor to the sauce.
• Thickening the Sauce: If you prefer a thicker sauce, you can remove the lid from the slow cooker during the last hour of cooking to allow some of the excess moisture to evaporate. Alternatively, you can stir in a tablespoon of cornstarch mixed with a little cold water during the last 30 minutes.

Serving & Storage Suggestions

This healthier slow cooker spaghetti sauce is incredibly versatile. Serve it over your favorite pasta, use it as a base for lasagna, or spoon it over polenta. It’s also delicious as a dipping sauce for mozzarella sticks or garlic bread.

To store leftovers, allow the sauce to cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 3-4 days. For longer storage, freeze the sauce in freezer-safe containers for up to 3 months. To reheat, thaw the sauce in the refrigerator overnight or use the defrost setting on your microwave. Reheat gently on the stovetop over medium heat, stirring occasionally, until heated through. You can also reheat it in the microwave.
