Cajun Beef Spaghetti in Creamy Parmesan Sauce

I created this Cajun beef spaghetti in creamy Parmesan sauce on a whim one night when I couldn’t decide between something spicy and something rich so I figured why not combine both and see what happens. I started with some Cajun spice rubbed into ground beef added a splash of cream and a generous handful of Parmesan and the result was bold creamy and full of warmth in the best way.

Ever since that evening it’s become one of my most requested dishes because it’s the kind of meal that feels indulgent but still comes together in one pan and I love how the spaghetti soaks up that spicy creamy sauce while every bite delivers a hit of smoky beef and nutty cheese.

Ingredients

Here’s what I use for this recipe. You can always make substitutions if you prefer!

• Spaghetti – The classic pasta shape that holds onto the creamy sauce beautifully.
• Ground beef – Adds hearty flavor and a little texture to balance the creaminess.
• Cajun seasoning – Brings the smoky, spicy heat that defines the dish.
• Heavy cream – The base for the velvety sauce that ties everything together.
• Parmesan cheese – Nutty and salty, it melts perfectly into the sauce.
• Garlic – Adds a fragrant kick that deepens the flavor.
• Onion – Slightly sweet and aromatic, a perfect start to the sauce.
• Olive oil – Helps sauté the onion and beef.
• Salt – Enhances all the flavors without overpowering.
• Black pepper – For a warm finishing touch.
• Fresh parsley – For garnish and a pop of green.

Tools You’ll Need

• Large skillet or sauté pan – Where the beef and sauce all come together.
• Pasta pot – For boiling the spaghetti to al dente perfection.
• Wooden spoon or spatula – To stir everything together smoothly.
• Grater – For fresh Parmesan (trust me it’s worth it).
• Knife and cutting board – To prep the onion and garlic.
• Measuring cups and spoons – To balance the seasoning and cream just right.

Instructions

Step 1:

I begin by boiling a large pot of salted water and cooking the spaghetti until al dente. I drain it and set it aside, saving a little pasta water in case the sauce needs thinning later.

Step 2:

While the pasta cooks, I heat olive oil in a large skillet and sauté the chopped onion until soft, then add garlic and cook for another minute.

Step 3:

I add the ground beef to the skillet and break it up with a spoon, cooking until browned. Then I sprinkle in the Cajun seasoning and mix well to coat the beef in flavor.

Step 4:

Once the beef is cooked and the spices are toasted, I pour in the heavy cream and stir to combine. I let it simmer gently for a few minutes to thicken slightly.

Step 5:

I stir in the grated Parmesan cheese and continue stirring until the sauce becomes creamy and smooth.

Step 6:

I toss in the cooked spaghetti and mix everything together, letting the pasta soak up the sauce. If it gets too thick, I loosen it with a splash of reserved pasta water.

Step 7:

I finish it off with freshly cracked black pepper, a little more Parmesan, and chopped parsley on top before serving.

Tips

I like to make my own Cajun blend if I want to control the heat, but store-bought works great too.

Don’t skip the reserved pasta water — it helps the sauce cling to the noodles perfectly.

For extra heat, add a pinch of cayenne or a dash of hot sauce.

This also works well with penne or fettuccine if you don’t have spaghetti on hand.

Ways to Serve

I love serving this with a side of garlic bread or toasted baguette slices.

A light arugula or Caesar salad balances the richness of the sauce.

Add sautéed mushrooms or spinach to sneak in extra veggies.

This dish is also delicious reheated the next day with just a touch of added cream or water.
