  • For the Cheese “Shells” 2 cups shredded low-moisture mozzarella
  • 3/4 cup grated Parmesan
  • 1 large egg
  • 1/2 teaspoon Italian seasoning
  • Pinch of garlic powder
  • For the Filling 1 tablespoon olive oil
  • 1 pound ground turkey (93% lean or similar)
  • 1/2 small onion, finely chopped
  • 2 cloves garlic, minced
  • 4 cups fresh spinach, chopped (or 1 cup thawed frozen, squeezed dry)
  • 1 cup whole-milk ricotta
  • 1/2 cup shredded mozzarella
  • 1/4 cup grated Parmesan
  • 1 large egg
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper
  • Pinch of red pepper flakes (optional)
  • For Assembly 1 1/2 cups low-carb marinara sauce (no added sugar)
  • 1/2 cup shredded mozzarella (for topping)
  • 2 tablespoons grated Parmesan (for topping)
  • Fresh basil or parsley, chopped (optional garnish)

Method
 

  1. Prep the oven and pan: Heat oven to 375°F (190°C). Line two baking sheets with parchment. Grease a 9x13-inch baking dish.
  2. Make the cheese shell mixture: In a bowl, mix mozzarella, Parmesan, egg, Italian seasoning, and garlic powder until a sticky dough forms.
  3. Form and bake the shells: Divide the mixture into 12 mounds on the lined sheets. With lightly oiled fingers, press each into a 3.5–4-inch circle. Bake 8–10 minutes until edges are lightly golden and centers set. Let cool 2–3 minutes so they’re flexible but not brittle.
  4. Cook the turkey: Warm olive oil in a skillet over medium heat. Add onion and cook 3–4 minutes until soft. Stir in garlic for 30 seconds.
  5. Brown and season: Add turkey, breaking it up. Cook until no longer pink, 5–6 minutes. Season with salt, pepper, Italian seasoning, and red pepper flakes if using.
  6. Add spinach: Stir in spinach and cook until wilted (or warmed through if using thawed), 1–2 minutes. Remove from heat and cool 5 minutes.
  7. Mix the filling: In a bowl, combine ricotta, mozzarella, Parmesan, egg, and the cooled turkey-spinach mixture. Taste and adjust salt and pepper.
  8. Sauce the dish: Spread 3/4 cup low-carb marinara on the bottom of the baking dish.
  9. Stuff the shells: Place 2–3 tablespoons of filling in the center of each cheese circle. Gently fold or cup into a shell shape. Arrange in the sauced dish, seam side up.
  10. Top and bake: Spoon remaining marinara over shells. Sprinkle with mozzarella and Parmesan. Bake 15–18 minutes until bubbly and lightly browned.
  11. Rest and serve: Let stand 5 minutes. Garnish with basil or parsley. Serve warm.
