First things first, get that linguine cooking according to the package directions. While it's happily bubbling away, make sure to scoop out about 1/2 cup of that starchy pasta water before you drain it. Trust me, you'll want this later!
While the pasta is doing its thing, let's get our chicken ready. Cut those boneless, skinless chicken breasts into nice, bite-sized pieces. Then, give them a good sprinkle of salt, black pepper, and that lovely paprika.

Heat up your olive oil in a nice, big skillet over medium-high heat. Once it's shimmering, toss in your seasoned chicken. Cook it until it's beautifully browned on all sides and cooked all the way through. Once it's ready, scoop the chicken out of the skillet and set it aside for a moment.

Lower the heat just a touch and add your butter to the same skillet. Once that butter is all melted and happy, toss in your minced garlic and those red pepper flakes. Give them a good sauté for about a minute until you can really smell that amazing aroma.

Reduce the heat to low. Now, stir in your grated Parmesan cheese. Keep stirring gently until the cheese melts into the sauce and it starts to thicken up beautifully. Oh, this is looking good!
