How to Make Creamy Parmesan Rotini with Cajun Garlic Butter Chicken
Okay, let’s get cooking! This dish comes together fast, so have everything prepped before you start. I’ve burned one too many garlic cloves in my rushing – learn from my mistakes! Follow these simple steps, and you’ll have the creamiest, most flavorful rotini ready in no time.
Cook the Pasta and Chicken
First, get that rotini boiling in well-salted water – it should taste like the sea! Cook it just until al dente (about 7-8 minutes). Save a cup of that starchy pasta water – it’s liquid gold for adjusting the sauce later. While the pasta cooks, heat olive oil in a big skillet and cook your Cajun-seasoned chicken strips over medium-high heat until they’re golden and juicy (about 4-5 minutes per side). Remove them to a plate – they’ll finish cooking in the sauce later.
Make the Cajun Garlic Butter Sauce
In that same skillet (don’t you dare wash it – all those browned bits add flavor!), melt the butter over low heat. Add the garlic and stir constantly for exactly 30 seconds – any longer and it’ll burn and taste bitter. Pour in the cold cream slowly, stirring as you go to prevent curdling. Now sprinkle in the parmesan a little at a time, whisking until it’s all melted and dreamy. Let it bubble gently for 2-3 minutes until it coats the back of a spoon.
Combine and Serve
Toss the cooked rotini and chicken into that luscious sauce, adding splashes of reserved pasta water if it gets too thick. Finish with a shower of fresh parsley – that pop of green makes it look fancy! Serve immediately while it’s piping hot and creamy.
Tips for Perfect Creamy Parmesan Rotini with Cajun Garlic Butter Chicken
After making this dish dozens of times (and yes, a few kitchen disasters!), here are my hard-won secrets:
- Freshly grate your parmesan – The pre-shredded stuff never melts as smoothly. I keep a block in my fridge just for this recipe.
- Don’t rush the sauce – Let it simmer those full 2-3 minutes to reach silky perfection. Stir constantly to prevent sticking!
- That pasta water is magic – I keep a mug by the stove to catch it before draining. Just 1-2 tablespoons can fix a too-thick sauce.
- Taste as you go – Cajun seasoning varies by brand. Add a pinch more if needed before adding the chicken back in.
Ingredient Substitutions
Ran out of something? No worries – here’s how to adapt without losing that amazing flavor:
- Half-and-half for heavy cream – It’ll be slightly less rich but still delicious. Just simmer longer to thicken.
- Gluten-free rotini – Works great! Cook 1 minute less than package says.
- Smoked paprika + cayenne – My hack when Cajun seasoning runs out (1 tsp each).
- Pecorino Romano – Saltier than parmesan, so taste first before adding extra salt.
Pro tip: Avoid pre-grated cheese substitutes – they make the sauce grainy!

Serving Suggestions for Creamy Parmesan Rotini with Cajun Garlic Butter Chicken
This dish is rich enough to shine on its own, but I love pairing it with a simple garlic bread for sauce-mopping and a crisp green salad to cut through the creaminess. My go-to? A lemony arugula salad – the peppery bite balances the Cajun spice perfectly. Whatever you do, skip heavy sides – this pasta is the real star of the show!
Storing and Reheating
Here’s the good news – leftovers taste amazing! Store them in an airtight container in the fridge for up to 3 days (though mine never lasts that long). When reheating, add a splash of milk and stir gently over low heat – it brings that creamy sauce right back to life. Microwave works too, but do 30-second bursts and stir between each to prevent separation. Pro tip: The pasta soaks up sauce as it sits, so don’t be shy with that extra milk!
FAQs About Creamy Parmesan Rotini with Cajun Garlic Butter Chicken
Can I use shrimp instead of chicken?
Absolutely! Just cook the shrimp for only 2-3 minutes in the skillet – they cook way faster than chicken. I’ve made this with both, and the sweet shrimp pairs amazingly with the spicy Cajun kick.
How spicy is this dish really?
It’s got a nice warmth but shouldn’t set your mouth on fire! Start with 1 tablespoon Cajun seasoning (or even 2 teaspoons if you’re nervous). You can always add more at the end – I keep extra on the table for spice lovers.
What’s the best pasta substitute if I don’t have rotini?
Penne works beautifully – those tubes catch the sauce just like the spirals do. Fusilli or cavatappi would be my next picks. Honestly though? Even plain spaghetti tastes incredible with this creamy Cajun sauce!
