Cook the pasta according to the package instructions until al dente. Drain and set aside, reserving about 1 cup of the pasta water.
In a large skillet over medium heat, melt the butter.
Add the minced garlic to the melted butter and sauté for about 1-2 minutes until fragrant, being careful not to burn it.
Stir in the diced chicken breast to the skillet. Season with salt, pepper, paprika, and cayenne pepper. Cook the chicken until it's browned and cooked through, about 6-8 minutes.
Add the chopped rosemary, thyme, and lemon juice to the chicken mixture, stirring to combine.
Fold in the cooked pasta and cherry tomatoes, drizzling in some of the reserved pasta water to help bring everything together and create a creamy sauce. Toss everything together until well combined and the pasta is heated through.
Adjust seasoning with additional salt, pepper, or lemon juice as desired.
Remove from heat and garnish with fresh parsley and grated Parmesan cheese if desired. Serve warm.
Notes
Adjust the cayenne pepper to taste for desired spiciness.
