What Cut of Steak Works Best for Cajun Garlic Butter Steak?

For this recipe, I usually go with sirloin or ribeye — both cuts have the perfect balance of tenderness and flavor. Sirloin is leaner but still juicy when cooked right, and ribeye is marbled and buttery, making it ideal for a high-heat sear. If you prefer something a little more budget-friendly, flank steak or flat iron can also work beautifully, just make sure to slice them thinly against the grain for the best texture.

No matter what cut you choose, the key is to not overcook the steak — medium-rare to medium is the sweet spot for flavor and juiciness. The Cajun seasoning adds a smoky, peppery crust that pairs like a dream with the creamy pasta.

Options for Substitutions

If you’re not into beef, chicken breast or shrimp make excellent substitutes — they soak up the Cajun seasoning just as well and cook quickly. You could also use a plant-based meat alternative for a vegetarian spin that still brings the heat.

For the tortellini, any cheese-stuffed variety will do, but if you’re feeling adventurous, try spinach and ricotta tortellini for a green twist. No Alfredo sauce on hand? A quick mix of heavy cream, garlic, Parmesan, and butter will give you a homemade version that tastes just as indulgent. And for a lighter option, swap the cream sauce with a garlic-infused olive oil drizzle and a sprinkle of Parmesan.

Ingredients for Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini

Steak (Sirloin or Ribeye):
This is the star of the dish — rich, flavorful, and perfect for a hot skillet sear. The fat content adds flavor and keeps the meat juicy.

Cajun Seasoning:
Adds that signature spicy kick with smoky, peppery, and garlicky notes. It forms a delicious crust when seared.

Butter:
Essential for both flavor and richness. It creates the base for the garlic butter finish on the steak.

Garlic (Minced):
This infuses the butter with bold flavor that pairs perfectly with the Cajun spice and tender beef.

Cheese Tortellini:
Stuffed pasta that brings creaminess and texture to the plate. It holds up well in the Alfredo sauce and makes the meal satisfying.

Alfredo Sauce:
Creamy, cheesy, and buttery — it ties the tortellini together and balances the heat from the steak.

Heavy Cream (if making sauce from scratch):
Forms the rich base for a homemade Alfredo. It adds body and a velvety texture to the sauce.

Parmesan Cheese (Grated):
For depth of flavor in the Alfredo sauce. It melts beautifully and gives the dish its signature cheesy finish.

Parsley (Chopped, for garnish):
Adds a pop of color and a fresh, herbal note that cuts through the richness.

Salt and Black Pepper:
Used to season the steak and enhance all the flavors without overpowering.

Step 1: Season the Steak

Pat your steak dry with a paper towel, then generously rub it with Cajun seasoning, salt, and black pepper on both sides. Let it rest at room temperature for about 15–20 minutes while you prep the pasta.

---

Step 2: Cook the Tortellini

Bring a large pot of salted water to a boil and cook the cheese tortellini according to package instructions. Drain and set aside, reserving a small cup of pasta water in case you need to loosen the sauce later.

---

Step 3: Sear the Steak

Heat a cast iron skillet or heavy pan over medium-high heat. Add a tablespoon of butter and a dash of oil. Once hot, place the steak in the pan and sear for 3–4 minutes per side, depending on thickness, until you reach your preferred doneness. Remove the steak from the pan and let it rest.

---

Step 4: Make the Garlic Butter

In the same skillet, lower the heat and add another 2 tablespoons of butter and the minced garlic. Stir until fragrant, about 1 minute. Spoon some of this garlic butter over the steak for extra flavor.

---

Step 5: Prepare the Alfredo Sauce

In a separate saucepan, warm Alfredo sauce over low heat. If making it from scratch, melt butter, add heavy cream, and stir in grated Parmesan until smooth and creamy. Season lightly with salt and pepper.

---

Step 6: Combine Pasta and Sauce

Add the cooked tortellini to the Alfredo sauce and stir gently to coat each piece. If the sauce is too thick, a splash of reserved pasta water will help loosen it.

---

Step 7: Plate and Garnish

Slice the rested steak into strips or cubes. Plate the Alfredo tortellini next to the steak, drizzle any remaining garlic butter over the top, and finish with chopped parsley.

---

How Long to Cook Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini

The total cook time for this dish is surprisingly quick. The steak takes about 6–8 minutes depending on thickness and desired doneness (plus 5 minutes resting time). Tortellini usually cooks in 3–5 minutes, and if you’re making Alfredo sauce from scratch, you’ll need 5–7 minutes more. From start to finish, expect everything to come together in about 30 minutes, making it a fantastic choice for weeknight dinners or last-minute dinner ideas.

Tips for Perfect Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini

• Let the Steak Rest: Don’t skip this step. Resting allows juices to redistribute so your steak stays tender and juicy.
• Don’t Overcrowd the Pan: If you’re cooking multiple steaks, give each piece space to develop that golden crust.
• Use Fresh Garlic: It makes all the difference in your butter. Jarred garlic won’t have the same punch.
• Balance the Heat: If your Cajun seasoning is extra spicy, consider a lighter hand or mix with a bit of brown sugar to mellow it.
• Homemade Sauce = Flavor Boost: A simple cream, butter, and Parmesan sauce tastes miles better than jarred, if you have the time.
• Reserve Pasta Water: It’s liquid gold when it comes to adjusting sauce consistency without watering it down.
• Finish with Parsley: It’s not just for color — it freshens up the richness of the dish beautifully.

Watch Out for These Mistakes While Cooking

• Overcooking the Steak: Cajun seasoning can burn quickly due to its spice content, so keep an eye on the heat and aim for a good sear without charring.
• Skipping the Rest Time: Cutting into the steak too soon will cause all the juices to run out — patience pays off.
• Boiling Tortellini Too Long: Overcooked tortellini becomes mushy and falls apart in the sauce. Follow the timing on the package closely.
• Using Too Much Cajun Seasoning: It’s bold and can overpower the dish. Start light — you can always add more.
• Letting the Garlic Burn: Burnt garlic tastes bitter and can ruin the butter base. Cook it low and slow.
• Sauce Too Thick or Thin: Always have reserved pasta water or a splash of cream on hand to adjust the consistency.
• Not Tasting as You Go: Both the sauce and steak seasoning benefit from little taste checks throughout the cooking process.

What to Serve With Cajun Garlic Butter Steak with Cheesy Alfredo Tortellini?

Roasted Asparagus

A crisp, fresh side that complements the creamy pasta and spicy steak.

Garlic Bread

For soaking up all that leftover Alfredo sauce and garlic butter.

Caesar Salad

Crunchy romaine, tangy dressing, and Parmesan bring balance and freshness.

Grilled Zucchini or Squash

Light and slightly smoky — a nice contrast to the richness of the main dish.

Steamed Broccoli

Adds some green to your plate and balances out the indulgence.

Caprese Salad

Tomato, mozzarella, and basil offer a refreshing counterpoint to the Cajun spice.

Buttered Corn on the Cob

Sweet and juicy — a classic Southern-style side that works beautifully here.

A Glass of Red Wine or Sparkling Water with Lemon

Whether you’re drinking or not, a little acidity in your beverage helps cleanse the palate between bites.

Storage Instructions

If you have leftovers (which is rare in my house!), they store beautifully with just a few simple steps. Place the steak and tortellini in separate airtight containers in the refrigerator. The tortellini with Alfredo sauce will keep for up to 3 days, and the steak will last about 3–4 days if properly sealed.

When reheating, gently warm the pasta over low heat on the stovetop with a splash of milk or cream to loosen the sauce. The steak can be reheated in a skillet with a bit of butter or quickly in the microwave — just be careful not to overdo it or it’ll turn rubbery. Freezing isn’t ideal for this dish since creamy sauces tend to separate, but the steak alone can be frozen for up to 2 months.

Frequently Asked Questions

Can I use frozen tortellini instead of fresh?

Absolutely. Just follow the cooking instructions on the package and be sure not to overcook — frozen tortellini tends to get soft quickly.

Is it okay to use pre-made Alfredo sauce?

Yes, store-bought Alfredo works well if you’re short on time. Look for one with minimal ingredients for the best flavor, or enhance it with garlic and Parmesan.

How spicy is Cajun seasoning?

It varies by brand. Some are mild and smoky, while others bring serious heat. Taste a pinch first and adjust based on your heat tolerance.

Can I cook the steak in advance?

You can, but fresh is best. If prepping ahead, slightly undercook it, then reheat gently with the garlic butter to avoid drying it out.

Is there a way to make this dish lighter?

Yes! Use half-and-half instead of heavy cream, swap in grilled chicken or shrimp for the steak, and go easy on the cheese. A garlic olive oil drizzle instead of Alfredo is another great light option.

Can I grill the steak instead of pan-searing it?

Definitely. A grill will add smokiness and char that works beautifully with Cajun seasoning. Just make sure to rest it before slicing.

What’s the best way to reheat leftovers?

Warm the pasta gently on the stove with a splash of milk or cream. Reheat the steak in a hot pan with a bit of butter, or microwave it on medium power to avoid overcooking.

Can I use a different type of pasta?

Sure — penne, fettuccine, or ravioli all work. Just make sure the pasta holds up to the creamy sauce and complements the steak.
