Ingredients

For the Cajun Steak:

• 1 lb (450g) sirloin or ribeye steak, cut into 1-inch strips
• 2 tablespoons Cajun seasoning (store-bought or homemade)
• 1 tablespoon olive oil
• 1 teaspoon kosher salt
• ½ teaspoon freshly ground black pepper

For the Cheesy Rigatoni:

• 12 oz (340g) rigatoni pasta
• 2 tablespoons butter
• 3 cloves garlic, minced
• 1 small onion, finely diced
• 1 red bell pepper, sliced
• 2 tablespoons all-purpose flour
• 1½ cups (360ml) whole milk
• ½ cup (120ml) heavy cream
• 1 cup (100g) freshly grated Parmesan cheese
• ½ cup (50g) shredded mozzarella cheese
• ¼ teaspoon cayenne pepper (optional, for extra heat)
• 2 tablespoons fresh parsley, chopped
• Salt and pepper to taste

The Cajun seasoning is the star flavor component, delivering a perfect blend of paprika, garlic, oregano, thyme, and cayenne. Using freshly grated Parmesan rather than pre-packaged varieties ensures the sauce achieves that silky-smooth texture that defines this spicy Cajun pasta dish.

Pro Tips

Perfect Steak Technique: For the best Cajun Steak Cheesy Rigatoni Parmesan, don’t overcrowd your pan when cooking the steak. Work in batches if necessary, as overcrowding causes the meat to steam rather than sear, preventing that beautiful caramelized crust from forming. Let the steak rest for at least 5 minutes after cooking and slice against the grain for maximum tenderness.

Sauce Consistency Control: The key to a perfectly creamy sauce is gradual heat and constant stirring. After adding flour to create your roux, cook it for at least 1-2 minutes to remove the raw flour taste. When adding milk and cream, pour slowly while whisking continuously to prevent lumps. If your sauce becomes too thick, add a splash of pasta water to thin it out while maintaining that silky texture.

Pasta Perfection: Always cook your rigatoni just to al dente (usually 1-2 minutes less than package directions) since it will continue cooking slightly when combined with the hot sauce. Reserve at least 1 cup of pasta water before draining – this starchy liquid is liquid gold for adjusting sauce consistency and helping the sauce adhere to the pasta. Never rinse your pasta after cooking, as the starch helps the cheesy sauce cling to each piece.

Instructions

Step 1: Prepare the Steak

Pat the steak pieces dry with paper towels (this ensures better browning). In a bowl, toss the steak strips with Cajun seasoning, salt, and pepper until evenly coated. Let the seasoned meat rest at room temperature for 15 minutes to absorb the flavors while you prepare other ingredients.

Step 2: Cook the Pasta

Bring a large pot of generously salted water to a rolling boil. Add the rigatoni and cook until al dente according to package instructions, usually 10-12 minutes. Before draining, reserve 1 cup of the starchy pasta water. Drain the pasta but don’t rinse it.

Step 3: Sear the Steak

Heat olive oil in a large skillet over medium-high heat until shimmering. Add the steak in a single layer, working in batches if necessary to avoid overcrowding. Sear for 2-3 minutes on each side for medium-rare, or longer if you prefer more doneness. Transfer the cooked steak to a plate and tent loosely with foil to rest.

Step 4: Make the Cheese Sauce

In the same skillet (don’t clean it – those steak bits add flavor!), reduce heat to medium and add butter. Once melted, add onions and sauté for 2-3 minutes until softened. Add the garlic and bell pepper, cooking for another 2 minutes until fragrant. Sprinkle the flour over the vegetables and stir constantly for 2 minutes to cook out the raw flour taste.

Step 5: Finish the Sauce and Combine

Gradually whisk in the milk and cream, stirring continuously to prevent lumps. Bring to a gentle simmer and cook for 3-4 minutes until slightly thickened. Reduce heat to low and gradually stir in the Parmesan and mozzarella until melted and smooth. Add cayenne pepper if using. Taste and adjust seasoning.

Add the cooked rigatoni to the sauce, tossing to coat each piece thoroughly. If the sauce seems too thick, add reserved pasta water a tablespoon at a time until you reach your desired consistency. Gently fold in the sliced steak, allowing it to warm in the sauce for 1-2 minutes.

Step 6: Serve

Transfer your Cajun Steak Cheesy Rigatoni Parmesan to a serving dish or individual plates. Garnish with fresh parsley and additional grated Parmesan if desired. Serve immediately while the cheese is still gloriously gooey and the pasta is hot.

Variations

Seafood Swap: Transform this dish into a Cajun surf and turf by replacing half the steak with shrimp or adding 8 ounces of andouille sausage for an authentic Louisiana flavor profile. The seafood pairs beautifully with the spicy Cajun seasoning and creamy cheese sauce, creating a different but equally delicious version of the Cajun Steak Cheesy Rigatoni Parmesan.

Vegetable Boost: For a more veggie-forward version, add sautéed mushrooms, zucchini, and cherry tomatoes to the sauce. The vegetables absorb the Cajun spices wonderfully while adding nutrition and color to the dish. You can even make it vegetarian by omitting the steak and doubling the vegetables, perhaps adding a protein boost with black beans.

Gluten-Free Option: This dish adapts well to dietary restrictions. Simply substitute gluten-free rigatoni or another gluten-free pasta shape with ridges to hold the sauce. For the sauce, replace all-purpose flour with a 1:1 gluten-free flour blend or cornstarch (using half the amount) to maintain that perfect creamy consistency.

Storage and Serving

This Cajun Steak Cheesy Rigatoni Parmesan can be refrigerated in an airtight container for up to 3 days. When reheating, add a splash of milk or cream and warm gently over medium-low heat, stirring occasionally to prevent the sauce from separating. Microwave reheating works in a pinch, but cover the dish and use 50% power for more even heating.

For an impressive presentation, serve this pasta in warmed bowls with a sprinkle of additional Parmesan cheese, red pepper flakes, and a side of garlic bread for soaking up every last bit of the decadent sauce. A simple arugula salad with lemon vinaigrette makes the perfect accompaniment, providing a fresh, peppery contrast to the rich pasta.

For an elevated dinner party serving, place the Cajun Steak Cheesy Rigatoni Parmesan in a large, shallow serving bowl and garnish with fresh herbs and lemon wedges. The bright colors and enticing aroma will make this dish the star of any table.

FAQs

Can I make this dish ahead of time?
Yes, but for best results, prepare the components separately. Cook the pasta al dente and toss with a bit of oil to prevent sticking. Make the sauce and refrigerate. Cook the steak and refrigerate. When ready to serve, gently reheat the sauce, adding a splash of milk if needed, then combine with the pasta and steak.

What can I substitute for rigatoni?
Any medium to large pasta shape with ridges works well. Penne, cavatappi, or fusilli are excellent alternatives as they trap the cheesy Cajun sauce in their crevices.

How spicy is this dish?
The spice level is moderate but customizable. For a milder version, reduce the Cajun seasoning to 1 tablespoon and omit the cayenne. For extra heat, add a diced jalapeño when sautéing the vegetables.

Can I use pre-shredded cheese?
Fresh-grated cheese melts much better than pre-shredded, which often contains anti-caking agents. If using pre-shredded, add an extra splash of cream to help it melt smoothly.

What cut of steak works best?
Ribeye, sirloin, or strip steak are ideal for their balance of tenderness and flavor. For a budget option, flank steak works well when sliced thinly against the grain.

This Cajun Steak Cheesy Rigatoni Parmesan is comfort food at its finest — a brilliant marriage of spicy, tender steak and creamy, cheesy pasta that satisfies all your cravings in one spectacular dish.
