Mix together the Cajun seasoning, garlic powder, salt, and cayenne pepper in a small bowl.
Sprinkle the seasoning mix over the chicken breasts, making sure they are evenly coated.
In a large skillet, heat some oil over medium-high heat.
Add the chicken breasts and cook until browned on both sides and cooked through, about 4-6 minutes per side.
Remove the chicken from the skillet and set aside.
In the same skillet, add the minced garlic and diced onion and cook until softened.
Add the chopped tomatoes, butternut squash, penne pasta, and chicken stock to the skillet.
Bring the mixture to a boil and simmer until the pasta is cooked and the sauce has thickened, about 10-12 minutes.
Stir in the quark cheese and grated Parmesan cheese until melted and creamy.
Season with salt and pepper to taste.
Slice the cooked chicken and stir it into the skillet.
Garnish with fresh basil and additional grated Parmesan cheese, if desired.
Serve hot and enjoy!
