Whether it's a busy weeknight or lazy weekend, it's my secret weapon when I want something big on flavor and low on dishes.
Ingredients
- Unsalted butter: Adds a final touch of silkiness while pulling all the flavors together
- Chopped parsley: Sprinkles in a punch of fresh, green taste Use flat-leaf if you can for best flavor
- Grated Parmesan cheese: Melts perfectly into the sauce Use Parmigiano Reggiano if you can splurge, or grab the best grated you can find
- Fettuccine pasta: The classic noodle for soaking up every bit of that creamy goodness Pick a rough-textured brand for extra cling
- Heavy cream: The reason the sauce is so luxuriously rich Buy the freshest cream on hand
- Chicken broth: Deepens the sauce with savory undertones Go with low-sodium if you want more salt control
- Minced garlic: Intensifies the sauce with full, real garlic flavor Choose firm, un-sprouted cloves
- Red pepper flakes: For folks who like things hot—adjust to your comfort Start with a little and ramp it up if you love heat
- Salt and black pepper: Brings everything into balance Fresh cracked pepper gives it more bite
- Smoked paprika: Infuses a mellow, woodsy note Try sweet paprika for gentle warmth, or spicy if you want extra punch
- Garlic powder and onion powder: Build a foundation of deep, savory flavor, making the Cajun pop
- Cajun seasoning: Packs in all that signature smoky heat Check for a salted blend if you want to keep tabs on the overall salt
- Boneless skinless chicken breasts: Lean, tender protein that turns juicy from the one-pan magic Look for chicken that's pink and stays in its own juices, not waterlogged
- Olive oil: Kicks things off and helps get your chicken those tasty brown bits Use the freshest oil you have for the best result
Step-by-Step Instructions
- Serve It Up:
- Scoop big spoonfuls of the finished pasta into bowls Top with fresh parsley and even more Parmesan if you want Every serving is creamy, a little spicy, and all about comfort
- Taste and Fix:
- Give the finished sauce a taste See if you want more salt, pepper, or Cajun spice and tweak as needed
- Herbs and Butter:
- Add a chunk of unsalted butter and scatter in chopped parsley Stir around until the butter melts and you see that shiny finish The parsley gives a nice fresh pop
- Mix in Chicken:
- Put those warm slices of chicken (and any juices left on the plate) back into your pan Stir so each strip gets coated in sauce and warms through again
- Make It Creamy:
- Once the pasta is done and the sauce has thickened, toss in Parmesan cheese Off the heat, keep stirring while it melts in so you end up with a glossy, creamy sauce
- Slice Your Chicken:
- While the pasta simmers, cut the rested chicken at an angle Slice into bite-size strips It's juiciest while still a little warm
- Cook Those Noodles:
- Push your dry fettuccine down into the sauce Make sure everything's submerged Pop a lid on and let it simmer, stirring every so often, around twelve minutes The liquid thickens and noodles turn glossy and tender
- Add Cream and Simmer:
- Mix in the heavy cream Gently heat until small bubbles show up on the edges—that's your sign to stop Don't boil so the cream stays silky
- Deglaze:
- Pour chicken broth straight into the hot pan Scrape up all the browned bits at the bottom with a wooden spoon All that stuck-on flavor melts into the sauce
- Sauté the Garlic:
- Toss minced garlic into the hot pan Stir fast for about 30 seconds Once it smells punchy, you're good Don't wait for it to brown or it can taste harsh
- Let the Chicken Rest:
- Move cooked chicken to a plate loosely covered with foil This helps lock in all the juices
- Sear the Chicken:
- Carefully place those coated chicken breasts into the hot oil Give them room Lay flat and leave them be (for about 7 minutes per side) until they're deep golden and the inside hits 165°F Don't flip early or you'll miss out on that tasty crust
- Season Up:
- Rub chicken breasts all over with Cajun seasoning, garlic powder, onion powder, smoked paprika, salt, pepper, and red pepper flakes Press the rub in so it sticks
- Get the Oil Hot:
- Glug olive oil into a deep skillet or Dutch oven Place it over medium-high heat Give it a sec until the oil shimmers but isn't smoking That's your green light for chicken

Storage Tips
Let your leftovers cool down before transferring to an airtight container Pop them into the fridge for up to three days Reheat slowly on the stove with a shot of milk or broth so the sauce stays silky Pasta can firm up in the fridge, so a drizzle of cream or broth brings it right back Avoid zapping in the microwave on full blast or the sauce could split
Ingredient Swaps
This dish plays nice with lots of swaps If you're bored of chicken, try smoked sausage slices or shrimp cubes Any pasta shape like penne or spaghetti gets the job done Half and half can step in for cream but it won't be quite as rich No block Parmesan? Find the best grated version you can grab
Serving Ideas
Pair up your pasta with a crisp green salad drizzled with vinaigrette or some garlicky broccolini Fresh warm bread soaks up all that sauce Want to change it up? Toss on some roasted cherry tomatoes or extra sautéed bell peppers before serving

Cultural context
Cajun food comes from French traditions mixed with Louisiana's local flavors and bold, peppery spices This creamy pasta definitely takes a creative turn—it fuses classic European cooking with comforting Southern style I love making this mashup when I’m craving something nostalgic but also want big flavors

Only cook chicken breasts until they hit 165°F, take them out to rest, slice them up, then add back in the sauce so they stay juicy.
