Season the chicken -
Cut chicken into ~1-inch pieces. Season with: 1 tablespoon + 1 teaspoon Cajun seasoning, All-purpose seasoning (to taste), Black pepper, Garlic powder (optional).
Cook the bacon -
In a large skillet over medium heat, cook bacon until crisp. Remove and chop.
Leave 1–2 tablespoon drippings in the pan (discard extra if needed).
Boil the pasta
- Bring a large pot of water to a boil and salt it lightly (optional if your Cajun mix is salty).
Cook penne until al dente. Reserve 1 cup pasta water, then drain.
Sauté onion & pepper
In the same skillet, sauté onion and bell pepper until softened (3–5 minutes).
Remove and set aside.
Cook the chicken
- Add chicken to the skillet (add a small drizzle of oil if needed). Cook until browned and cooked through (165°F internal), about 6–10 minutes. Remove and set aside.
Start the sauce
In a saucepan or the same skillet over medium-low heat, melt 2 tablespoon butter.
Add garlic paste, sun-dried tomatoes, and tomato paste. Cook 2–3 minutes, stirring often, until fragrant and the tomato paste deepens slightly.
Add cream + Cajun seasoning
- Reduce heat to low. Stir in heavy cream. Add: 2 teaspoon Cajun seasoning, All-purpose seasoning (to taste), smoked paprika and/or cayenne).
Bring to a gentle simmer (don’t boil).
Melt in parmesan
- Add parmesan ½ cup at a time, stirring until smooth before adding more. Keep heat low to avoid clumping.
Taste the sauce—if you want it more Cajun-forward, add 1 more teaspoon Cajun seasoning (bringing sauce Cajun to 3 tsp).
Combine everything
- Add pasta to the sauce. Add chicken, sautéed onion/bell pepper, and bacon. Toss well.
Add reserved pasta water ¼ cup at a time until the sauce is silky and coats the pasta perfectly.
