I call this ‘Grandma’s Secret Sauce’ because it’s so rich and flavorful, it tastes like it took hours (but it didn’t)!

1 tablespoon olive oil
1 onion, finely chopped
2 cloves garlic, minced
1 pound ground beef
1 can (28 ounces) crushed tomatoes
2 tablespoons tomato paste
1 teaspoon dried oregano
1 teaspoon dried basil
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 cup beef broth
1 tablespoon Worcestershire sauce
1 bay leaf
1 pound spaghetti
Freshly grated Parmesan cheese, for serving

1. In a large skillet, heat the olive oil over medium heat. Add the onion and garlic and sauté until the onion is translucent.

2. Add the ground beef to the skillet and cook until browned, breaking it up with a spoon as it cooks.

3. Transfer the cooked beef mixture to the slow cooker.

4. Add the crushed tomatoes, tomato paste, oregano, basil, salt, pepper, beef broth, Worcestershire sauce, and bay leaf to the slow cooker. Stir to combine.

5. Cover and cook on low for 6-8 hours or on high for 3-4 hours.
