If you’re looking for a pasta recipe that’s both comforting and packed with protein, this Grilled Chicken Protein Pasta is the perfect answer. Juicy marinated chicken thighs are grilled to perfection and served over a creamy cottage cheese–based sauce with rotini pasta and spinach. The result? A high-protein meal that’s filling, nutritious, and absolutely satisfying.
Unlike traditional heavy cream pasta sauces, this one uses low-fat cottage cheese and skim milk, creating a silky, protein-rich base without sacrificing flavor. Pair it with grilled chicken for extra lean protein, and you’ve got a meal that’s just as good for meal prep as it is for a family dinner.
Ingredients
For the Chicken Marinade:
- 1–1.5 lb boneless, skinless chicken thighs
- 2 tbsp avocado oil
- Salt and black pepper, to taste
- 1 tsp garlic powder
- 1 tsp dried oregano
- 1 tsp dried parsley
For the Pasta:
- 12 oz rotini pasta
- 16 oz low-fat cottage cheese
- ½ cup skim milk
- ⅓ cup grated Parmesan cheese
- 2 cloves garlic
- Salt and black pepper, to taste
- 2 cups finely chopped spinach
- ¼ cup reserved pasta water
Instructions
- Marinate the Chicken
- In a bowl, mix avocado oil, salt, pepper, garlic powder, oregano, and parsley.
- Add chicken thighs and coat well. Marinate for at least 30 minutes (longer if possible for more flavor).
- Grill the Chicken
- Heat your grill (or grill pan) to medium-high.
- Cook chicken for 4–5 minutes per side until fully cooked (internal temp 165°F).
- Let rest for a few minutes before slicing.
- Cook the Pasta
- Boil rotini pasta according to package instructions. Reserve ¼ cup of pasta water, then drain.
- Make the Protein Sauce
- In a blender, combine cottage cheese, skim milk, Parmesan, garlic, and a pinch of salt and pepper. Blend until smooth and creamy.
- Pour the sauce into the same pot you used for the pasta, set to LOW heat.
- Add chopped spinach and stir until wilted. Adjust seasoning with salt and pepper.
- Bring It All Together
- Stir in the reserved pasta water to loosen the sauce.
- Add the cooked pasta and mix until fully coated. Remove from heat (the sauce will thicken as it cools slightly).
- Serve
- Plate the pasta in shallow bowls, top with sliced grilled chicken, and finish with a crack of fresh black pepper and extra Parmesan if desired.
