This creamy Cajun chicken pasta is pure comfort food the kind of bowl you crave after a long day. The spicy kick in the Cajun sauce clings to every strand of fettuccine while the golden seared chicken brings just the right amount of hearty protein. Every bite is rich and bold but still easy enough for a Tuesday night.
One wild thunderstorm sent me hunting for a meal that would warm us from the inside out and this was it. Ever since then I catch myself craving that creamy spicy sauce especially when I spot chicken breasts on sale.
Ingredients
- Boneless skinless chicken breasts: Tender and quick cooking with lots of protein Look for meat that is plump and pink with clear juices
- Olive oil: Gives a beautiful sear and silky mouthfeel Choose extra virgin for best depth of flavor
- Cajun seasoning: Brings the signature bold spicy taste Opt for a fresh blend if you can or see the spice aisle for one that lists paprika and herbs high on the label
- Garlic powder and onion powder: Boost flavor in both chicken and sauce Go for powders with no added salt or fillers
- Smoked paprika: Builds a deeper flavor than regular paprika Seek out Spanish smoked varieties for extra aroma
- Salt and black pepper: Brightens and balances all the spices Use fresh ground pepper for a little extra punch
- Fettuccine pasta: Wide flat noodles that cradle the sauce Cook just until al dente and always salt your cooking water well
- Butter: Adds rich flavor and helps toast the garlic Look for real butter not margarine for best results
- Fresh garlic: Adds fragrant warmth Mince just before using for the best taste
- Heavy cream: Creates the luscious creamy sauce Pasteurized cream will give a smooth result
- Chicken broth: Thins the sauce without watering down flavor Use low sodium to control saltiness
- Grated Parmesan cheese: Melts into the cream for nutty flavor Grate real Parmesan for the smoothest finish Avoid pre grated if possible
- Chopped fresh parsley: Brightens the creamy pasta Flat leaf parsley tastes fresher than curly
- Lemon juice: Lifts the dish with acidity Fresh squeezed brings the best zip

- Sear the Chicken:
- Lay chicken into the hot oil and cook six to seven minutes per side Let it get a deep golden crust and check that juices run clear before moving on

- Slice the Chicken:
- Cut the rested chicken breasts into thin strips that will nestle atop the pasta
- Combine with Pasta:
- Add the drained fettuccine into the skillet with the creamy sauce Gently toss so every strand gets coated If sauce is too thick add a little reserved pasta water

Parmesan is the ingredient I look forward to every time Its salty nutty flavor melts right in making the sauce rich but never overwhelming My cousin once tried this with pre shredded cheese and had grainy sauce so I never skip freshly grating mine by hand
Storage Tips
Leftovers keep well in a sealed container in the refrigerator for up to three days To reheat add a dash of cream or broth and warm gently on the stove or microwave If sauce has thickened too much stir in a spoonful of pasta water
Ingredient Substitutions
Feel free to swap in half and half for a lighter dish You can also use penne or linguine if you are out of fettuccine For a vegetarian twist use thick strips of sautéed mushrooms or tofu and vegetable broth instead of chicken
Serving Suggestions
A side of crunchy garlic bread or a crisp green salad balances the richness perfectly Add extra lemon wedges on the side so everyone can brighten their own bowl as they like

Recipe FAQs
- → How can I adjust the spice level?
Increase or decrease the amount of Cajun seasoning to your liking, or add cayenne for extra heat.
- → What kind of pasta works best?
Fettuccine is classic, but penne, linguine, or spaghetti also pair well with the creamy sauce.
- → Can I use half-and-half instead of heavy cream?
Yes, half-and-half can lighten the sauce while still providing creaminess, though it may be slightly less rich.
- → What’s the best way to keep the chicken tender?
Let the chicken rest a few minutes after cooking before slicing, so juices stay sealed inside.
- → Are there vegetable add-ins that work well?
Bell peppers or spinach can be sautéed with the garlic for added flavor, texture, and color.
- → Is freshly grated Parmesan important?
Freshly grated Parmesan melts more smoothly, giving the sauce a silkier texture and richer taste.
