Ingredients

Units Scale

For the Sauce

  • 1 (28-ounce) can crushed tomatoes
  • 1 (15-ounce) can crushed tomatoes or tomato sauce
  • 3/4 medium onion, finely diced
  • 1 bay leaf
  • 1 teaspoon sugar
  • 1/2 teaspoon crushed red pepper flakes
  • 1/2 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper

For the Meatballs

  • 3/4 cup breadcrumbs
  • 1/2 cup milk
  • 4 cloves garlic, minced
  • 1/4 medium onion, finely diced
  • 1/4 cup chopped fresh parsley
  • 1 3/4 teaspoons freshly ground black pepper
  • 1 3/4 teaspoons kosher salt
  • 1 teaspoon dried oregano
  • 1/2 cup shredded Pecorino Romano or Parmesan cheese
  • 1 large egg
  • 1 pound ground 90/10 beef
  • 1 pound ground Italian turkey sausage

Instructions

  1. Make the sauce: Set your slow cooker to low, then add all of the crushed tomatoes, onion, bay leaf, sugar, red pepper flakes, salt, and pepper. Give it a quick stir to combine everything.
  2. Soak the breadcrumbs: In a medium-sized bowl, combine the breadcrumbs and milk, letting the breadcrumbs soak and soften.
  3. Add the other meatball ingredients: To the soaked breadcrumbs, add the minced garlic, diced onion, chopped parsley, black pepper, kosher salt, dried oregano, shredded Pecorino Romano cheese, and egg. Mix well with a fork, then add the ground beef and Italian turkey sausage. Use your hands to gently combine everything, taking care not to overwork the mixture.
  4. Shape the meatballs: Wet your hands with water to prevent sticking or use a small #40 cookie scoop. Pinch off about a tablespoon of meat, roll into balls slightly smaller than a golf ball, and place them directly into the tomato sauce in the slow cooker. Repeat until all meatballs are formed. It's normal if some meatballs are not fully submerged; they will cook into the sauce as they simmer.
  5. Cover and cook: Secure the slow cooker lid and cook the meatballs for 5 hours on high heat or 8 to 10 hours on low heat, allowing the flavors to meld and the meatballs to become tender.
  6. Serve: Serve these meatballs over spaghetti, in hoagie buns for sandwiches, or as appetizers on their own. For a thicker sauce, transfer it to a skillet over medium-high heat to reduce until desired consistency. Stir any fat floating on the top back into the sauce before serving.

Notes

  • Keeping your hands wet while rolling the meatballs prevents sticking and makes shaping easier.
  • A small cookie scoop helps create uniformly sized meatballs quickly and efficiently.
  • If you prefer, substitute the Pecorino Romano cheese with Parmesan cheese.
  • Leftover meatballs can be refrigerated for up to 3 days or frozen for up to 3 months.
  • Use gluten-free breadcrumbs and verify other ingredients for gluten-free compliance if needed.
  • For a spicier sauce, increase the crushed red pepper flakes slightly.
  • Removing the bay leaf before serving is recommended as it is not meant to be eaten.
