Slow Cooker Spaghetti Sauce

makes 6-8 servings

For the sauce:

1 tablespoon olive oil

2 medium carrots (3/4 cup), finely diced

1 stalk celery (1/2 cup), finely diced

1/2 large onion (1 cup), finely chopped

2-3 garlic cloves, minced (about 1 tablespoon)

2 tablespoons tomato paste

1 pound grass-fed ground beef (90 percent lean)

1/2 teaspoon dried thyme

1/2 teaspoon dried basil

1/2 teaspoon dried parsley

1 teaspoon dried oregano

1 teaspoon fine sea salt

1/2 teaspoon freshly ground pepper

pinch nutmeg

pinch crushed red pepper flakes

1/2 cup 1 percent milk

1/2 cup dry red wine

1 28-ounce can San Marzano whole peeled tomatoes

1 bay leaf

To serve:

cooked pasta, such as spaghetti

fresh basil, for garnish

1. Add the oil to a large skillet and heat over medium heat. Add the carrot, celery, and onion, and saute until the vegetables have softened, 6 to 8 minutes. Add the garlic and the tomato paste, and cook until the garlic is fragrant, about 30 seconds.

2. Add the beef, breaking it apart with a wooden spoon, and cook it until just browned. Stir in the thyme, parsley, basil, oregano, salt, pepper, thyme, nutmeg, and crushed red pepper flakes.

3. Stir in the milk and bring to a simmer. Continue simmering until the milk has reduced completely and most of the liquid has been absorbed, about 10 minutes. Stir in the wine and simmer again until almost completely reduced, about 10 minutes. Transfer the beef mixture to the bowl of a 6-quart slow cooker.

4. Strain the tomatoes through a fine-mesh strainer, reserving the juices. Carefully add the tomatoes to the slow cooker, smashing them against the side of the slow cooker with a spoon or smooshing them through your fist to break the tomatoes down into bite-size pieces.

5. Add the bay leaf to the slow cooker and stir everything together. If the mixture looks too dry, add a little bit of the reserved tomato juice.

6. Place the lid on the slow cooker and cook on low for 6 to 8 hours.

7. When only 30 minutes of cooking time remains, check the sauce. If it looks very liquidy, remove the lid to let the excess liquid evaporate. If it looks too dry, stir in a little bit of the reserved tomato juice.

8. Serve the sauce over pasta and garnish with fresh basil. You can keep the leftover sauce in the refrigerator in an airtight container for up to one week.
