Cook the linguine according to package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium-high heat. Add the chicken pieces, season with salt, pepper, and Italian seasoning, and cook until golden brown and cooked through, about 5-7 minutes.

Reduce the heat to medium, add the butter and garlic to the skillet with the chicken, and cook for another 2 minutes until the garlic is fragrant.
Toss the cooked linguine in the skillet with the chicken and garlic butter sauce.
Sprinkle the Parmesan cheese over the pasta and chicken, stirring to combine until the cheese is melted and everything is well coated.
Garnish with fresh parsley before serving.
Variations & Tips
For a lighter version, you can use whole wheat or gluten-free pasta. If you’re a fan of spice, add a pinch of red pepper flakes to the garlic butter sauce. You can also swap the chicken for shrimp or tofu for a different protein. For a touch of brightness, squeeze a bit of lemon juice over the finished dish.
