Ingredients You’ll Need

One of my favorite things about Creamy Cajun Steak Penne Pasta is that the ingredients are simple, but together they create serious flavor.

For the Steak

1.25 lb sirloin steak, sliced into bite-size strips
2 tbsp olive oil
1 tbsp Cajun seasoning
1 tsp garlic powder
1 tsp smoked paprika
1/2 tsp salt
1/2 tsp black pepper

For the Pasta and Sauce

12 oz penne pasta
2 tbsp butter
3 cloves garlic, minced
2 cups heavy cream
1 cup whole milk
1.5 cups shredded mozzarella cheese
1 cup freshly grated Parmesan cheese
4 oz cream cheese, softened
1 tsp garlic powder
1/2 tsp onion powder

Optional Garnishes

Fresh parsley
Extra Parmesan cheese
Red pepper flakes

How to Make Creamy Cajun Steak Penne Pasta

1. Cook the Pasta

Bring a large pot of salted water to a boil and cook the penne pasta until tender. You want it perfectly al dente so it holds onto that creamy sauce without turning mushy.

Drain the pasta and set it aside. Try not to snack on half the noodles while cooking. It happens to the best of us.

2. Season the Steak

In a bowl, toss the steak strips with olive oil, Cajun seasoning, garlic powder, smoked paprika, salt, and black pepper.

The smoky paprika and Cajun spices create a bold crust that gives the steak incredible flavor. Every piece should look beautifully coated.

3. Sear the Steak

Heat a large skillet over medium-high heat and melt the butter.

Add the steak strips in a single layer and sear for about 2 to 3 minutes per side until browned and caramelized.

Don’t overcrowd the pan. Steak likes personal space. If the skillet gets crowded, the meat steams instead of sears, and nobody wants sad gray steak.

Once browned, add the minced garlic and cook for about 30 seconds until fragrant.

Remove the steak from the skillet and set aside.

4. Make the Creamy Cajun Sauce

Using the same skillet keeps all those flavorful browned bits right where they belong.

Melt a little more butter if needed, then whisk in flour and cook for about 1 minute. This helps create a smooth, velvety sauce.

Slowly pour in the heavy cream and milk while whisking continuously.

Let the sauce simmer gently until it starts to thicken. Your kitchen will smell like a cozy little bistro at this point.

5. Add the Cheese

Stir in the mozzarella, Parmesan, and cream cheese.

Keep stirring until the cheese melts into a silky, ultra-creamy sauce.

Season with garlic powder, onion powder, salt, and pepper to taste.

This sauce is luxurious, cheesy, and packed with flavor. If Alfredo sauce went on vacation to Louisiana, this would probably be the result.

6. Combine Everything

Add the cooked penne pasta directly into the skillet and toss until every noodle is coated in creamy Cajun goodness.

Top with the steak and gently mix everything together, or leave the steak layered on top for a more dramatic presentation.

Finish with parsley, extra Parmesan, and red pepper flakes if you want a little more heat.

Then grab a fork immediately because waiting is honestly the hardest part.

Chef Omar’s Best Tips for Creamy Cajun Steak Penne Pasta

Don’t Overcook the Steak

Sirloin cooks quickly, especially when sliced thin. A fast sear keeps the meat juicy and tender.

Freshly Grated Cheese Makes a Difference

Pre-shredded cheese often contains anti-caking agents that can make sauces grainy. Freshly grated cheese melts much smoother.

Balance the Creaminess

One home cook added a splash of lemon juice at the end because the sauce felt extra rich, and the result was incredible. That little bit of brightness cuts through the cream beautifully.

Adjust the Spice Level

Love heat? Add extra Cajun seasoning or red pepper flakes.

Cooking for kids or spice-sensitive guests? Start with less Cajun seasoning and build from there.

Try Different Proteins

This recipe works wonderfully with chicken too. One family swapped the steak for breaded chicken because steak wasn’t a household favorite, and everyone still raved about the sauce.

Another cook used Havarti instead of mozzarella because it was all they had in the fridge, and the creamy texture turned out absolutely dreamy.

That’s the beauty of recipes like this—they’re flexible enough to work with real life.

What to Serve with Creamy Cajun Steak Penne Pasta

This dish is rich and hearty, so lighter sides pair beautifully.

Here are a few favorites:

Garlic bread for soaking up every last bit of sauce
A crisp Caesar salad
Roasted broccoli or asparagus
Simple green beans with lemon
A chilled cucumber salad

And if you’re hosting friends? Add a big bowl of pasta to the center of the table and let everyone dig in family-style. It’s cozy, casual, and always a hit.

A Little Story From Chef Omar’s Kitchen

This Creamy Cajun Steak Penne Pasta became a regular in my kitchen after a last-minute dinner situation that could’ve gone very wrong.

A few friends stopped by unexpectedly one evening, and I had exactly one package of pasta, some steak in the fridge, and enough dairy products to open a tiny cheese shop.

So naturally, I threw everything into one skillet and hoped for the best.

The moment the Cajun spices hit the pan, everyone wandered into the kitchen pretending they were “just checking on dinner.” Ten minutes later, people were scraping the skillet for extra sauce with pieces of bread.

That’s when I knew this recipe needed a permanent place in the rotation.

Now it’s one of those dependable meals that feels comforting enough for a Tuesday night but impressive enough for company.

FAQs About Creamy Cajun Steak Penne Pasta

Can I make Creamy Cajun Steak Penne Pasta ahead of time?

Yes. You can prepare the pasta and sauce ahead of time and store it in the fridge for up to 3 days. Reheat gently on the stove with a splash of milk to loosen the sauce.

Can I use a different pasta shape?

Absolutely. Rigatoni, fettuccine, rotini, or even shells work well with the creamy Cajun sauce.

What’s the best steak for this recipe?

Sirloin is great because it cooks quickly and stays tender. Ribeye or strip steak also work beautifully if you want an even richer flavor.

Is Creamy Cajun Steak Penne Pasta very spicy?

Not overly spicy. The cream and cheese mellow out the Cajun seasoning quite a bit. If you prefer more heat, simply add extra seasoning or crushed red pepper flakes.

Can I freeze leftovers?

Cream-based sauces can sometimes separate after freezing, so this dish is best enjoyed fresh or refrigerated for a few days.

Can I make this lighter?

You can swap part of the heavy cream for half-and-half or use less cheese. The sauce won’t be quite as rich, but it’ll still be delicious.
