Season the chicken: Sprinkle chicken tenders on both sides with salt, pepper, garlic powder, and paprika.
Sear the chicken: Heat olive oil in a large skillet over medium heat. Add the chicken and cook for 3–4 minutes per side, until golden and fully cooked. Remove and set aside.
Start the sauce: In the same skillet, melt the butter. Add minced garlic and sauté for 30 seconds until fragrant.
Add cream: Pour in heavy cream, stir, and season with a small pinch of salt. Bring to a gentle simmer.
Melt in cheese: Lower the heat and whisk in Parmesan cheese until smooth and thickened.
Stir in parsley: Add chopped fresh parsley for a burst of color and freshness.
Toss with pasta: Add cooked fettuccine noodles to the sauce and toss until evenly coated. Let it sit for a minute or two to absorb the sauce.
Serve: Slice the cooked chicken and place on top of the pasta. Garnish with extra Parmesan and parsley.
