Place each chicken breast between plastic wrap and pound to an even thickness, about 1/2 inch.
Lightly coat both sides of the chicken breasts with olive oil, then sprinkle about 1 tablespoon Creole/Cajun seasoning evenly over both sides.
Heat a large skillet over medium-high heat. When hot, add the chicken and cook until blackened and cooked through, about 3 minutes per side (adjust time for thickness).
While the chicken cooks, heat the Alfredo sauce and roasted garlic together in a small saucepan or in the microwave until warmed through.
Stir the cooked, drained bowtie pasta into the warmed Alfredo sauce and toss to coat evenly.
Divide the sauced pasta between two bowls, thinly slice the cooked chicken, and arrange the slices on top of the pasta.
Serve immediately and sprinkle with Parmesan cheese if desired.
