Cut the chicken breast into bite-sized pieces and set aside. Pat the pieces dry with paper towels for better browning.
Cook the linguine in a pot of salted boiling water according to package instructions until al dente. Drain and set aside, reserving a small cup of pasta water.
In a large skillet, melt butter and olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant, stirring constantly so it doesn’t brown.
Add the chicken pieces to the skillet and season with lemon juice, lemon zest, Italian seasoning, salt, black pepper, and red pepper flakes.
Cook the chicken for 5–7 minutes, stirring occasionally, until browned on the outside and cooked through (internal temp 165°F / 74°C).
Add the cooked linguine to the skillet and toss to coat in the sauce. If the sauce seems dry, add 1–2 tablespoons of reserved pasta water to loosen it.
Stir in fresh parsley and remove from heat. Taste and adjust salt or lemon as needed.
Serve hot, topped with Parmesan cheese. Enjoy!
Notes
Pat chicken dry before cooking for better texture. Use freshly squeezed lemon juice and zest for the best flavor.
