A creamy and satisfying high protein Alfredo bake made with tender chicken, broccoli, and protein-rich pasta. The sauce blends cottage cheese, Greek yogurt, and Parmesan for a smooth, rich texture while keeping the dish lighter and packed with over 30g of protein per serving.

  • Total Time: 50 minutes
  • Yield: 6 servings

Ingredients

Scale
  • 8 oz high protein pasta (such as chickpea or lentil pasta)
  • 1 lb chicken breast, cut into bite-sized pieces
  • 2 cups broccoli florets
  • 1 cup cottage cheese
  • 1/2 cup plain Greek yogurt
  • 1/2 cup grated Parmesan cheese
  • 2 cloves garlic, minced
  • 1 tbsp olive oil
  • 1/2 cup chicken broth
  • 1/2 cup milk
  • 1 tsp Italian seasoning
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1 cup mozzarella cheese, shredded

Instructions

  1. Preheat oven to 375°F (190°C) and grease a 9×9-inch baking dish.
  2. Cook pasta 1–2 minutes less than package directions. Drain and set aside.
  3. Heat olive oil in a large skillet over medium heat. Add chicken pieces and cook until no longer pink and the internal temperature reaches 165°F, about 5–7 minutes.
  4. Add broccoli to the skillet and cook another 3–4 minutes until slightly tender.
  5. In a blender, combine cottage cheese, Greek yogurt, Parmesan cheese, garlic, chicken broth, milk, Italian seasoning, salt, and pepper. Blend for 45–60 seconds until completely smooth.
  6. Pour the sauce over the chicken and broccoli mixture and stir well.
  7. Add the cooked pasta and mix until evenly combined.
  8. Transfer the mixture to the prepared baking dish and top with shredded mozzarella cheese.
  9. Bake for 20–25 minutes until bubbly around the edges and the cheese is melted with golden spots.
  10. Let cool for 5 minutes before serving.

Notes

  • You can substitute chicken with turkey or add extra vegetables like spinach or mushrooms.
  • For extra protein, add a scoop of unflavored protein powder to the sauce.
  • Make ahead by assembling the dish up to 24 hours in advance and refrigerating before baking.
  • Leftovers can be stored in the refrigerator for up to 4 days or frozen for up to 2 months.
