Step‑by‑Step Instructions for High Protein Stuffed Shells
Step 1: Preheat and Prepare Shells
Begin by preheating your oven to 400°F (200°C). While it’s warming up, cook your jumbo shells according to the package instructions until they’re al dente. This should take about 10 minutes. Drain the shells and set them aside, ensuring they are cool enough to handle while you prepare the filling and sauce.
Step 2: Cook the Turkey Mixture
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the ground turkey, cooking it until browned, which will take about 5-7 minutes. Once browned, stir in a tablespoon of Italian seasoning and your marinara sauce. Reduce the heat to low and allow the mixture to simmer for 10 minutes, bringing those flavors together beautifully.
Step 3: Mix the Cheese Filling
In a mixing bowl, combine 1 cup of ricotta cheese, ½ cup of Parmesan cheese, 1 cup of mozzarella cheese, and 1 beaten egg. Add in the chopped spinach, an additional teaspoon of Italian seasoning, and a pinch of red pepper flakes for a hint of heat. Mix thoroughly until you achieve a creamy, well-combined filling for your High Protein Stuffed Shells.
Step 4: Stuff the Shells
Now it’s time for the fun part! Take each cooked shell and stuff it generously with approximately 1 tablespoon of the ricotta mixture. Place each filled shell seam-side up into a baking dish that has been layered with the turkey marinara sauce. This helps keep the shells moist and flavorful during baking.
Step 5: Bake to Perfection
Once all the shells are arranged, sprinkle additional mozzarella or Parmesan cheese on top for an extra cheesy finish. Cover the baking dish with foil to retain moisture, and place it in the oven. Bake for 20 minutes, until the cheese is bubbly and the dish is thoroughly heated through, with a golden melty layer on top.
Step 6: Serve and Enjoy
After baking, carefully remove the foil and let the High Protein Stuffed Shells cool for a few minutes. This will make serving easier. You can garnish with fresh herbs or more cheese if desired. Enjoy this comforting dish with your loved ones, savoring the delightful combination of flavors!
