Ingredients

  • 1 small yellow onion
  • 2 cups baby spinach, loosely packed
  • 1 cup fresh basil leaves, loosely packed
  • 4 tablespoons grated parmesan cheese
  • 1 teaspoon granulated garlic powder
  • 1 teaspoon kosher salt
  • 1 ¼ lb 93% lean ground turkey
  • 2 teaspoons olive oil
  • 1 (24-oz) jar marinara sauce

Instructions

  • Grate the onion using the large holes of a box grater over a large bowl. You should end up with about ¼ cup.
  • Chop the spinach and basil finely into very small pieces. Alternatively you can add the onion, basil, and spinach to a food processor and pulse until finely chopped but not pureed.
  • To the same bowl, add the parmesan cheese, garlic powder, and salt, stirring to combine. Add the turkey and stir again, until all the ingredients are well incorporated.
  • Add the olive oil to the base of a 6-quart slow cooker, spreading it around until the bottom is well coated.
  • Using a small, 1.6-inch cookie scoop, scoop the turkey mixture into a single layer into the base of the slow cooker. Gentle scoop any remaining mixture on top, creating a second layer. If you don’t have a cookie scoop, you can use a large soup spoon instead. You can also roll the ground turkey mixture into balls by hand, but it it's too sticky, use the scoop or spoon method.
  • Pour the marinara sauce over the meatballs. Do not stir.
  • Cover and cook on high for 3-4 hours or low for5-6 or until the meatballs are cooked through and tender. Uncover and gently stir to separate the meatballs.
  • Serve over pasta, spaghetti squash, or with crusty bread, topped with fresh basil, parmesan (traditional or dairy-free), and red pepper flakes if desired.

Notes

  • Dairy-Free: For a dairy-free version, omit the parmesan and substitute 1 tablespoon nutritional yeast.
  • Serving: My recipe makes enough meatballs for 1 pound cooked pasta. Toss the cooked pasta with the sauce and then top with the meatballs.
  • Meatballs: Don't stir the meatballs once they're in the slow cooker. They need time to set before they can handle any movement or they'll fall apart.
