The first time I made this Creamy Cajun Steak Penne Pasta, Jake had just picked up a bottle of smoked paprika from our local spice shop after our weekend trip to explore some authentic Southern cooking. I had a piece of flank steak in the fridge and some penne leftover from another meal. The combination of that deeply smoky spice with tender strips of beef and a luscious cream sauce felt almost magical.
Now this Creamy Cajun Steak Penne Pasta has become a regular in our dinner rotation. The sauce is velvety and clings to every piece of penne. The Cajun seasoning brings a gentle warmth without overwhelming the dish. The steak, sliced thin and seared quickly at high heat, stays tender and juicy.
What I love most about this Creamy Cajun Steak Penne Pasta is how quickly it comes together. In about 30 minutes, I have a complete dinner on the table that tastes like something from a restaurant. My kids, Lily and Noah, never complain about this one, and that is saying something.

Creamy Cajun Steak Penne Pasta Ingredients
You probably already have most of these ingredients in your pantry. The key to an exceptional Creamy Cajun Steak Penne Pasta is using quality Cajun seasoning and cooking your steak correctly. Do not skip the step of patting your steak dry before seasoning. Moisture is the enemy of that beautiful sear you want.
- 450g (1 lb) flank steak or sirloin, thinly sliced against the grain. This cut gives you the tenderness you need for your Creamy Cajun Steak Penne Pasta.
- 400g (14 oz) penne pasta, cooked according to package directions. Reserve 120ml (½ cup) of pasta water before draining.
- 240ml (1 cup) heavy cream, for that rich, velvety sauce base.
- 120ml (½ cup) low-sodium chicken broth, helps deglaze the pan and thin the sauce slightly.
- 2 tablespoons Cajun seasoning, this is the flavor backbone of your Creamy Cajun Steak Penne Pasta. Use a quality blend or make your own.
- 4 cloves garlic, minced. Fresh garlic adds brightness that balances the smoky Cajun spices.
- 1 medium yellow onion, diced. This adds sweetness and depth to the sauce.
- 60g (½ cup) freshly grated Parmesan cheese, stirred in at the end for extra richness and saltiness.
- 2 tablespoons olive oil, for searing the steak at high heat.
- 1 teaspoon smoked paprika, enhances the smoky Cajun flavor profile.
- Salt and black pepper, to taste. Remember your Cajun seasoning already contains salt.
- Fresh parsley, for a bright finishing touch. About 2 tablespoons chopped.
- 1 cup cherry tomatoes, halved (optional, for color and freshness).
About That Cajun Seasoning: The Cajun seasoning you choose makes or breaks this recipe. Store-bought blends work fine, but if you have the time, mix together 1 tablespoon each of paprika, garlic powder, onion powder, oregano, and thyme with 1 teaspoon cayenne pepper. This gives you a fresh, potent blend that really shines in your Creamy Cajun Steak Penne Pasta. You can find more information about spice blending techniques at Serious Eats spice guides.
The Steak Matters: For the most tender Creamy Cajun Steak Penne Pasta, use flank steak or sirloin. These cuts have enough marbling to stay juicy during the quick sear, and slicing them thin against the grain breaks up the muscle fibers for a melt-in-your-mouth bite.
Pasta Water is Liquid Gold: Do not forget to save some of that starchy pasta water. It helps your sauce cling to the penne and adds body to the finished dish. This is the secret technique that makes restaurant pasta taste so good.
Note: If you want a lighter version of this Creamy Cajun Steak Penne Pasta, you can substitute half the heavy cream with whole milk. The sauce will be slightly thinner but still delicious. I have made this adjustment many times when I am trying to keep things a bit healthier for my family.
How to Make Creamy Cajun Steak Penne Pasta
First, gather all your ingredients and tools. Having everything ready before you start cooking keeps the process smooth and prevents your steak from getting cold while you hunt for measuring spoons. A hot pan and a quick hand with your spatula are the keys to perfecting your Creamy Cajun Steak Penne Pasta.
Step 1: Prepare Your Steak
Pat your 450g (1 lb) flank steak completely dry with paper towels. Moisture is the enemy of a good sear, and we need that caramelized crust on your Creamy Cajun Steak Penne Pasta steak. Once dry, season both sides generously with 1 tablespoon of your Cajun seasoning, ½ teaspoon garlic powder, and salt and black pepper to taste.
Let the steak sit at room temperature while you bring a large pot of salted water to a boil. This 10-minute rest allows the seasoning to adhere and the meat to cook more evenly.
Lora’s Tip: Use a paper towel and press firmly on both sides of the steak. You want it bone dry before it hits the hot pan.
Step 2: Cook Your Pasta
Boil your 400g (14 oz) penne according to package directions. You want it al dente, about 1 minute less than the package suggests. Before you drain it, scoop out 120ml (½ cup) of that starchy pasta water. This liquid gold will help thicken your sauce later. Set your drained pasta aside and keep it warm.
Step 3: Sear the Steak Perfectly
Heat your large cast-iron skillet over high heat until it is smoking slightly. Add 2 tablespoons olive oil and let it shimmer. Place your seasoned steak strips in a single layer. Do not crowd the pan or the steak will steam instead of sear.
You should hear a loud sizzle when the steak hits the oil. Your Creamy Cajun Steak Penne Pasta steak needs about 2 minutes per side. Look for a deep golden-brown crust before you flip. Once cooked, transfer the steak to a clean plate and tent it loosely with foil.
Lora’s Tip: Work in batches if needed. Your pan should have space around each strip for the steam to escape. This takes about 90 seconds extra but makes a huge difference in texture.
Step 4: Build Your Creamy Cajun Sauce
In the same skillet with all those tasty brown bits left behind, add your diced onion. Cook over medium heat for about 3 minutes until softened and translucent. Add your 4 minced garlic cloves and cook for another 30 seconds until fragrant. The smell at this point should be absolutely incredible.
Pour in your 120ml (½ cup) chicken broth and use a wooden spoon to scrape up all those caramelized bits from the bottom of the pan. These fragments are pure flavor. Let the broth reduce by half, about 2 minutes.
Next, add your 240ml (1 cup) heavy cream, remaining 1 tablespoon Cajun seasoning, and 1 teaspoon smoked paprika. Stir everything together and bring to a gentle simmer. Let the sauce thicken for about 4 minutes, stirring occasionally. The sauce is ready when it coats the back of your spoon and you can draw a line through it with your finger.
Step 5: Combine Pasta and Sauce
Add your drained penne directly to the skillet with the sauce. Toss everything together using tongs or two spoons, making sure every piece of pasta gets coated with that beautiful creamy sauce. If the sauce seems too thick, add splashes of your reserved pasta water until you reach your desired consistency.
Sprinkle in your 60g (½ cup) freshly grated Parmesan and stir until melted and incorporated. The sauce should be glossy and cling to every piece of pasta.
Step 6: Add the Steak and Finish
Slice your rested steak into thin strips against the grain. Fold the steak gently into your Creamy Cajun Steak Penne Pasta, reserving a few pieces for topping. Add your halved cherry tomatoes if using, and give everything one more gentle toss.
Remove from heat and finish with a generous handful of fresh chopped parsley. Serve immediately while the sauce is still silky and the steak is warm and juicy.
Lora's Kitchen Tips
- Hot Pan, Happy Steak: Make sure your skillet is truly hot before adding the steak. A drop of water should dance and evaporate immediately. This ensures the Maillard reaction happens, creating that golden-brown crust that makes your Creamy Cajun Steak Penne Pasta taste like it came from a steakhouse.
- Rest Your Meat: After cooking your steak, let it rest for 5 minutes before slicing. This allows the juices to redistribute throughout the meat. Slicing too early means all those delicious juices end up on your cutting board instead of in your pasta.
- Sauce Too Thin? If your cream sauce seems too runny, do not panic. Simply let it simmer for an extra 2-3 minutes while stirring. The sauce will thicken as it reduces. You can also add more Parmesan to thicken and enrich the texture.
- Sauce Too Thick? Add splashes of reserved pasta water or additional chicken broth until you reach that perfect creamy consistency. The starchy pasta water is especially good because it adds body without watering down the flavor.
- Prevent Chewy Steak: The number one mistake people make with this Creamy Cajun Steak Penne Pasta is overcooking the steak. Flank steak becomes tough if cooked past medium-rare to medium. Slice it thin, sear it fast, and get it back off the heat quickly. The residual heat will finish cooking it while it rests.
Creamy Cajun Steak Penne Pasta Variations and Substitutions
The beauty of this Creamy Cajun Steak Penne Pasta is how easily it adapts to your preferences and what you have on hand. Here are some variations I have tried with great success.
Lighter Version: Substitute half the heavy cream with whole milk or plain Greek yogurt. The sauce will be slightly thinner but still rich and satisfying. This works beautifully when I want to keep things a bit healthier for my family.
Vegetables Add-In: Add diced bell peppers, mushrooms, or spinach to the sauce. Sauté them with the onion for extra nutrition and color. My kids actually eat the spinach when it is hidden in this creamy pasta.
Spicy Kick: For those who love heat, add an extra ½ teaspoon of cayenne pepper or a few dashes of your favorite hot sauce directly to the cream sauce. This makes the Creamy Cajun Steak Penne Pasta even more bold and warming.
Protein Swap: Shrimp works wonderfully in this dish. Add peeled and deveined shrimp after cooking the sauce, and they will be done in about 3-4 minutes. You can even do half steak and half shrimp for a surf-and-turf version.
What to Serve with Creamy Cajun Steak Penne Pasta
This Creamy Cajun Steak Penne Pasta is a complete meal on its own, but I always like to round out the dinner table with a few simple sides.
A side of crusty garlic bread is perfect for soaking up every drop of that amazing cream sauce. My family fights over the last piece every single time. I also love serving a simple green salad with a tangy vinaigrette to cut through the richness of the pasta.
For a comforting Southern-inspired spread, try serving your Creamy Cajun Steak Penne Pasta alongside some Cajun Sausage and Rice Skillet. The flavors complement each other beautifully and you have a complete Southern feast on the table.
As for beverages, a glass of dry white wine like Sauvignon Blanc pairs wonderfully with the creamy, slightly spicy notes of this dish. For a non-alcoholic option, I love a glass of sparkling water with lemon, which helps cleanse the palate between bites.
