Pro Tips Before You Start
Grate Parmesan fresh – Pre-shredded cheese won’t melt as smoothly.
Don’t boil after adding cheese – High heat can cause separation.
Taste before salting – Cajun seasoning blends vary in saltiness.
Adjust spice to preference – Reduce cayenne for mild or add extra for heat lovers.
Zest before cutting lemon – It’s much easier to get zest from a whole lemon.
How to Make Cajun Parmesan Cream Sauce
Step 1 – Melt the butter
In a large skillet over low heat, melt the butter until it froths and tiny white bubbles appear.

Stir in heavy cream and Cajun seasoning.
If needed, add salt. Bring to a gentle simmer and cook for 5–6 minutes, allowing flavors to infuse.
Step 3 – Add lemon zest & Parmesan
Remove skillet from heat.
Stir in lemon zest, then gradually add Parmesan, mixing until completely melted and the sauce is smooth.
Adjust salt to taste.
Step 4 – Serve
Toss with hot cooked pasta or pour over your favorite protein or vegetables.
What to Serve It With
Fettuccine or linguine for a classic pasta dish.
Cajun-spiced shrimp or blackened chicken.
Roasted vegetables like asparagus, broccoli, or zucchini.
Garlic bread to soak up every bit of sauce.
A crisp green salad for balance.
Variations / Substitutions

Cheese swap – Try Pecorino Romano for a sharper flavor.
Seafood version – Add seared scallops or lobster chunks.
Storage & Leftovers
