Bring a large pot of salted water to a boil and cook the pasta according to package instructions until al dente.
Reserve 1/4 cup of the pasta cooking water before draining.
In a blender or food processor, combine cottage cheese, Greek yogurt, and Parmesan cheese. Blend until completely smooth.
Heat olive oil in a large skillet over medium-high heat. Season chicken with salt, pepper, and garlic powder.
Sauté chicken for 6-8 minutes until golden brown and cooked through to an internal temperature of 165F.
Reduce heat to low. Add minced garlic and sauté for 1 minute until fragrant.
Pour the blended sauce into the skillet with the chicken. Stir in the reserved pasta water to reach desired consistency.
Add the cooked pasta to the skillet and toss to coat thoroughly. Heat gently for 2 minutes, ensuring the sauce does not boil.
Garnish with fresh parsley and serve immediately.
