Bold, buttery, and bursting with creamy indulgence—this Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini is the ultimate weeknight luxury. Thick-cut steak bites are seasoned to perfection with Cajun spice, seared until beautifully crusted, and finished in a rich garlic butter glaze. Pair that with pillowy cheese tortellini drenched in a luscious Alfredo sauce, and you’ve got a dinner that feels like a restaurant masterpiece but made right at home.

This dish is all about balance—spicy meets creamy, seared meets soft, indulgent meets weeknight doable. The Cajun kick of the steak balances the velvety, cheesy pasta with harmony in every bite. It’s perfect for date night, a cozy family dinner, or any time you want to treat yourself without fussing over complicated steps.

What Kind of Steak Should I Use?

For best results, go for a well-marbled cut like ribeye, sirloin, or New York strip. These cuts stay tender and juicy even after searing, making them ideal for steak bites. Avoid overly lean cuts, which may dry out quickly and won’t hold up as well to the high-heat sear and Cajun seasoning.

Ingredients for the Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini

Steak (Ribeye or Sirloin): Rich in flavor and fat, these cuts sear beautifully and stay tender inside.

Cajun Seasoning: The star of the show—adds heat, smokiness, and color. Adjust to your spice level.

Butter: Essential for creating that glossy, flavorful garlic butter sauce that coats each steak bite.

Fresh Garlic: Minced garlic caramelizes in the butter, infusing it with deep, savory notes.

Cheese Tortellini: Store-bought or homemade, these stuffed pasta pillows bring cheesy, comforting flavor.

Alfredo Sauce: Creamy, garlicky, and cheesy—ties the dish together with a velvety touch.

Parsley: Fresh chopped parsley adds color and a mild herbal contrast to all the richness.

Olive Oil: Helps create a perfect sear on the steak while keeping it moist.

Salt & Pepper: To season the steak simply before the Cajun spices go on.

How To Make the Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini

Step 1: Prep the Steak

Pat your steak dry with paper towels, then cut it into bite-sized cubes. Season generously with salt, pepper, and Cajun seasoning, tossing until every piece is well coated.

Step 2: Sear the Steak

Heat olive oil in a large skillet over medium-high heat. Once shimmering, add the steak bites in a single layer. Let them sear undisturbed for 2–3 minutes to form a crust, then flip and cook for another 2–3 minutes until browned and cooked to your preferred doneness. Remove from skillet and set aside.

Step 3: Make the Garlic Butter Sauce

In the same skillet, reduce the heat to medium and add butter. Once melted, stir in minced garlic and sauté for 30 seconds until fragrant. Return the steak bites to the skillet and toss to coat in the garlic butter. Remove from heat.

Step 4: Cook the Tortellini

While the steak is cooking, boil the cheese tortellini according to package instructions. Drain and set aside.

Step 5: Warm the Alfredo Sauce

In a separate pan, gently heat the Alfredo sauce over low heat until warmed through. Add the cooked tortellini and stir to coat evenly.

Step 6: Plate and Serve

Spoon the creamy Alfredo tortellini onto a plate and top with buttery Cajun steak bites. Garnish with chopped parsley and a fresh crack of black pepper. Serve hot and enjoy every luxurious bite.

How to Serve and Store Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini

This dish is best served fresh while the steak is juicy and the sauce is silky. Serve it family-style or plated individually for a more elegant presentation. A simple side salad or garlic bread rounds out the meal beautifully.

To store, allow leftovers to cool completely. Transfer to airtight containers and refrigerate for up to 3 days. Reheat gently in a skillet over low heat or in the microwave in 30-second intervals, adding a splash of cream or milk to loosen the sauce if needed.

Frequently Asked Questions

Can I use frozen tortellini?

Yes! Frozen tortellini works perfectly. Just follow the package instructions for cooking time.

What if I don’t have Cajun seasoning?

You can make a quick blend with paprika, garlic powder, onion powder, thyme, oregano, cayenne, salt, and pepper.

Can I make this ahead of time?

It’s best fresh, but you can prep the steak and sauce ahead. Reheat everything just before serving.

Is there a way to make this less spicy?

Absolutely. Use less Cajun seasoning or swap it with a mild smoked paprika for flavor without heat.

What Alfredo sauce should I use?

Homemade is great, but store-bought works well too. Choose one with real cream and cheese for best flavor.

Can I grill the steak instead of pan-searing?

Definitely! Grilling adds a smoky twist. Just toss the cooked steak bites in garlic butter afterward.
