Let’s dive into the recipe and walk through how to make it from start to finish!

Ingredients You’ll Need

Here’s everything you need to bring this delicious dinner to life:

• 1 pound sirloin or ribeye steak, cut into bite-sized pieces

• 1 tablespoon olive oil

• 2 teaspoons Cajun seasoning

• ½ teaspoon salt

• ½ teaspoon black pepper

• 12 ounces rigatoni pasta

• 2 tablespoons unsalted butter

• 3 cloves garlic, minced

• 1 cup heavy cream

• 1 cup whole milk

• 1 cup grated Parmesan cheese

• 1 cup shredded mozzarella cheese

• ½ teaspoon paprika

• ¼ teaspoon crushed red pepper flakes (optional)

• Chopped parsley for garnish

STEP 1: Cook Your Rigatoni Just Right

Start by bringing a large pot of salted water to a boil. Cook your rigatoni according to the package instructions until it’s al dente—firm but cooked through. You don’t want mushy pasta here since it’ll simmer a bit more later in the sauce.

Once it’s cooked, drain and set it aside while you move on to the star of the show—the Cajun steak tips.

STEP 2: Season the Steak Tips

In a medium bowl, toss your bite-sized steak pieces with the Cajun seasoning, salt, and black pepper. If you have the time, you can marinate the steak for an hour beforehand with the Cajun seasoning and a splash of olive oil to really let the flavors soak in. But if you’re short on time (like I usually am), even a quick seasoning does the trick beautifully.

STEP 3: Sear That Steak

Heat a tablespoon of olive oil in a large skillet over medium-high heat. Once it’s hot, add the steak tips in a single layer. Let them sear for about 2–3 minutes per side. You want a good browning on the outside while keeping the inside juicy and tender.

Try not to overcrowd the pan—cook in batches if you need to. Once the steak is seared, remove it from the pan and set it aside on a plate.

Now, don’t clean that skillet! All those little browned bits (aka flavor gold) are going to help make our sauce extra delicious.

STEP 4: Build the Creamy Cheese Sauce

With the steak out of the pan, reduce the heat to medium and add your butter. Once it’s melted, stir in the minced garlic and sauté for about 30 seconds. You just want it fragrant—not browned or burnt.

Now pour in the heavy cream and milk, and stir gently until it starts to simmer. Slowly add in your grated Parmesan and shredded mozzarella, stirring constantly until the sauce becomes thick and creamy. Don’t rush this part—it should be smooth, velvety, and ready to coat every piece of pasta like a dream.

Cajun Steak Tips in Cheesy Rigatoni Parmesan Sauce: A Bold and Creamy Pasta You’ll Crave 

Now that we’ve got our steak tips seared to perfection and the base of our creamy cheese sauce bubbling away, it’s time to bring everything together into one seriously crave-worthy skillet. This part of the process is all about layering in that bold flavor, giving everything time to meld together, and making sure every single bite is packed with creamy, cheesy goodness and spicy Cajun kick.

Whether you’re cooking for guests or just treating yourself to something extra cozy, this step is where the magic really happens.

STEP 5: Season the Sauce with Spice

Once your cheese has fully melted into the cream mixture and your sauce is looking smooth and luscious, it’s time to add a little more flavor to deepen things.

Stir in the ½ teaspoon of paprika and ¼ teaspoon of crushed red pepper flakes if you’re using them. This step is optional if you’re not into heat, but it adds such a nice warm background flavor that pairs beautifully with the Cajun-seasoned steak. The crushed red pepper gives it just the right amount of kick without overpowering the dish.

At this point, your sauce should be creamy, rich, and just slightly spicy—the perfect base for our rigatoni and steak to come back in.

STEP 6: Add the Cooked Rigatoni to the Sauce

Now, gently stir your cooked rigatoni into the cheesy sauce. Make sure every piece is fully coated. The rigatoni is perfect for this kind of sauce because all those ridges and the hollow center trap the cheesy goodness and make each bite extra satisfying.

If your sauce looks a little thick at this point, you can stir in a splash of milk or even some reserved pasta water (if you thought ahead and saved some!) to loosen it up just a bit. Don’t overdo it though—you still want it rich and creamy, not watery.

STEP 7: Return the Steak Tips to the Pan

Once your pasta is coated, return the seared steak tips to the skillet. Gently toss them with the pasta and sauce until everything is mixed and warmed through. Let it simmer together for about 1 to 2 minutes, just enough time for all the flavors to meld and for the steak to absorb some of that cheesy, garlicky sauce.

If you like a little extra char or crispness on the steak, you can toss them back in the pan first for a minute before adding the pasta—but honestly, this dish is all about that soft, creamy blend of textures.

STEP 8: Garnish and Serve

Take the skillet off the heat and sprinkle with chopped fresh parsley for a pop of color and freshness. It’s a small step, but it really helps brighten up the dish.

From here, you can serve it straight from the skillet (my preferred method—less cleanup!) or transfer it to a large serving bowl if you’re feeling fancy. Either way, this is one of those meals where people will be going back for seconds… and probably thirds.

Helpful Tips and Simple Variations

Now let’s talk about a few tips and tricks that can take this dish to the next level, or help you customize it to what you have on hand:

• Marinate for More Flavor: If you’ve got a bit of extra time, marinating your steak tips in Cajun seasoning and a little olive oil for about an hour before cooking can seriously deepen the flavor. Just cover and refrigerate them while the pasta’s cooking or while you’re prepping the rest.

• Mix Up the Pasta: Rigatoni is my go-to here, but if you don’t have it, you can absolutely use penne, cavatappi, or even fettuccine. The key is using something that holds up well to the heavy sauce.

• Add Veggies: Want to sneak in some veggies or add more texture? Sautéed mushrooms, bell peppers, or even spinach go great in this dish. Just cook them after the steak and before the sauce so you can use those flavors in the pan to build your base.

• Make It a Casserole: If you’ve got leftovers (or if you double the recipe), you can bake this in a casserole dish topped with extra mozzarella and a sprinkle of breadcrumbs for a crunchy, cheesy topping. Pop it under the broiler for a few minutes until bubbly and golden.

• Pairing Ideas: This pasta is rich and filling on its own, but if you’re looking for sides, a crisp green salad with a tangy vinaigrette helps cut through the richness, and garlic bread is a no-brainer for soaking up every last bit of sauce.
