Imagine this: tender, juicy sirloin steak tips, seared to perfection and coated in a fiery, aromatic blend of Cajun spices. They’re nestled into a bed of rigatoni pasta, whose generous tubes are perfectly designed to catch every drop of a luxuriously smooth and cheesy Parmesan sauce.

In under an hour, you’ll have a restaurant-quality meal on the table that is guaranteed to become a new family favorite. Let’s dive into how you can create this masterpiece in your own kitchen.

The Cultural Fusion on Your Plate

While this specific recipe is an original creation, it draws inspiration from two distinct and beloved culinary traditions. Cajun cuisine, born from the French-speaking Acadian immigrants in Louisiana, is known for its robust, rustic, and deeply flavorful dishes. It’s a “country” cuisine that makes incredible use of spices, the “holy trinity” of onions, bell peppers, and celery, and techniques like blackening and searing to build complex layers of taste.

On the other side, we have the timeless Italian love affair with pasta and Parmesan. A simple, cheesy pasta sauce is a cornerstone of Italian comfort food, celebrating the quality of a few simple ingredients. This recipe marries the bold, assertive personality of Cajun cooking with the creamy, comforting embrace of an Italian-inspired cheese sauce. The result is a fusion that feels both exciting and familiar, a testament to how global flavors can come together to create something entirely new and delicious.

The ingredient list for this dish is a collection of pantry staples and a few fresh items that pack a powerful punch. Using high-quality components, especially the steak and the cheese, will make a significant difference in the final result.

Ingredients

For the Cajun Steak Tips:

1.5 pounds sirloin steak tips or sirloin steak, cut into 1-inch cubes
2 tablespoons olive oil
1 tablespoon homemade or store-bought Cajun seasoning (see note for salt content)
1 teaspoon smoked paprika
½ teaspoon garlic powder
½ teaspoon onion powder
¼ teaspoon black pepper
¼ teaspoon salt (adjust based on your Cajun seasoning)

For the Cheesy Rigatoni Parmesan Sauce:

12 ounces rigatoni pasta
3 tablespoons unsalted butter
1 medium yellow onion, finely diced
1 red bell pepper, finely diced
3 cloves garlic, minced
3 tablespoons all-purpose flour
3 cups whole milk, warmed
1 cup chicken or beef broth
2 cups freshly grated Parmesan cheese, plus more for serving
1 cup shredded Italian cheese blend (or mozzarella/provolone)
½ cup heavy cream
¼ cup fresh parsley, chopped, plus more for garnish
1 teaspoon dried oregano
Salt and black pepper to taste

Step-by-Step Instructions

Follow these steps carefully for a flawless, restaurant-quality result.

Prepare the Pasta and Steak: Bring a large pot of salted water to a boil. Cook the rigatoni according to package directions until al dente. Drain and set aside. While the water is heating, pat the steak tips completely dry with paper towels. In a medium bowl, toss the steak tips with the olive oil, Cajun seasoning, smoked paprika, garlic powder, onion powder, black pepper, and salt until evenly coated.
Sear the Steak Tips: Heat a large, heavy-bottomed skillet or cast-iron pan over medium-high heat until very hot. Add the seasoned steak tips in a single layer, ensuring they are not crowded (you may need to do this in two batches). Sear for 2-3 minutes per side without moving them, until a deep brown crust forms. The steak will be medium-rare at this point. Remove the steak tips from the skillet and set them aside on a plate. They will finish cooking later in the sauce.
Sauté the Aromatics: Reduce the heat to medium. In the same skillet, you should have beautiful rendered fat and browned bits. Add the butter and let it melt. Add the diced onion and red bell pepper and sauté for 5-7 minutes, until softened and fragrant. Add the minced garlic and cook for another minute until fragrant.
Create the Roux: Sprinkle the flour over the onion and pepper mixture. Cook, stirring constantly, for about 1-2 minutes until the raw flour smell is gone and the mixture turns a light golden color. This is the base of your sauce and will thicken it perfectly.
Build the Creamy Sauce: Gradually pour in the warm milk and broth, whisking constantly to prevent any lumps from forming. Bring the mixture to a gentle simmer, continuing to whisk until it begins to thicken, about 3-5 minutes.
Incorporate the Cheeses: Reduce the heat to low. Stir in the grated Parmesan and Italian cheese blend until the cheese is fully melted and the sauce is smooth. Then, stir in the heavy cream and dried oregano. Season the sauce with salt and pepper to taste. Remember, the Parmesan is salty, so taste first before adding more salt.
Combine and Finish: Add the cooked, drained rigatoni and the seared steak tips (along with any accumulated juices) back into the skillet with the cheese sauce. Gently toss everything together until the pasta and steak are evenly coated in the luxurious sauce. Let it heat through for 2-3 minutes so the steak tips reach your desired final level of doneness.
Serve Immediately: Garnish with a generous sprinkle of fresh chopped parsley and extra grated Parmesan cheese. Serve hot directly from the skillet for a truly impressive presentation.

Pro Tips for Perfection

Don’t Crowd the Pan When Searing: This is the golden rule for a perfect sear. If you add too many steak tips at once, they will steam instead of sear, and you’ll miss out on that beautiful, flavorful crust. Work in batches if necessary.
Grate Your Own Cheese: Pre-shredded cheese contains anti-caking agents like potato starch or cellulose, which can prevent your sauce from becoming perfectly smooth. For the creamiest, silkiest sauce, always buy a block of Parmesan and grate it yourself.
Warm Your Milk: Adding cold milk to a roux can sometimes cause it to seize or become lumpy. Taking a minute to warm the milk in the microwave or a saucepan before adding it will help it incorporate seamlessly into the roux for a flawlessly smooth sauce.
Control the Heat: If you or your family are sensitive to spice, you can use a mild Cajun seasoning or make your own blend, adjusting the amount of cayenne pepper. On the flip side, spice lovers can add a pinch of cayenne or red pepper flakes to the sauce for an extra kick.
Rest Your Steak: Allowing the seared steak tips to rest on a plate before adding them back to the sauce ensures the juices redistribute throughout the meat, resulting in a more tender and flavorful bite.

Delicious Variations to Try

This recipe is wonderfully adaptable. Feel free to make it your own with these simple twists:

Protein Swap: Not in the mood for steak? Chicken breast or thighs, cut into bite-sized pieces, work beautifully with the Cajun seasoning. Shrimp is another fantastic and quick-cooking alternative.
Vegetable Boost: Add a cup of sliced mushrooms when you sauté the onions and peppers. Fresh spinach or kale can be stirred in at the very end until just wilted.
Creamy Tomato Twist: For a rosé-style sauce, stir in ¼ cup of tomato paste after the vegetables have softened and cook for a minute before adding the flour.
Different Pasta: While rigatoni is ideal for holding the sauce, penne, ziti, or fusilli are all excellent substitutes.

Serving Suggestions

This dish is a complete meal in itself, but you can round out the dinner table with a few simple sides:

A crisp, green salad with a light vinaigrette to balance the richness of the pasta.
A loaf of crusty, warm garlic bread for sopping up every last bit of the cheesy sauce.
For a lighter option, simple steamed green beans or roasted asparagus make elegant accompaniments.
