Step 1

Cook pasta according to package directions on the box. Drain and set aside.

Step 2

Pat dry the chicken breasts with a paper towel. Season with cajun seasoning and rub it all around.

Step 3

Heat olive oil in a large skillet or cast-iron pan over medium-high heat. Add chicken and cook for 5-6 minutes, flip, and cook for an additional 6-7 minutes. (If using large chicken breasts, cut them in half horizontally to make thinner cuts. They will cook quicker.) Remove chicken to a plate and cover with foil.

Step 4

Melt butter in the same skillet or saucepan. Add diced onion and saute for 3-4 minutes. Add in the minced garlic, and cook until fragrant, about 1-2 minutes.

Step 5

Whisk in heavy cream, lemon zest, and grated parmesan. Whisk for 2 minutes or until the sauce has thickened. Season with salt and pepper, to taste.

Step 6

Slice the chicken and add on top of the pasta. Spoon the sauce over the top and then garnish with diced tomatoes, parsley, green onions, and shredded parmesan. Enjoy immediately.
