Ingredients You’ll Need

These ingredients may seem straightforward, but each one plays a key role in building the layers of flavor and texture that make this skillet meal unforgettable. From the spice-kissed steak to the luscious cheesy garlic sauce coating the pasta shells, every component matters.

1 ½ lbs sirloin steak or ribeye: Tender, juicy beef cut into bite-sized cubes, perfect for quick cooking and bold flavor absorption.
2 tbsp Cajun seasoning: Provides that signature spicy kick and aromatic blend that defines the dish.
2 tbsp olive oil: For searing the steak to a beautiful crust without drying it out.
2 tbsp unsalted butter (plus extra for shells): Adds richness and helps elevate the garlic flavors throughout.
2 cloves garlic, minced (plus extra for shells): Garlic delivers its magical depth and aromatic punch both in the steak and the pasta.
Salt and pepper, to taste: Essential seasonings that bring harmony and enhance natural flavors.
Fresh parsley, chopped: A bright, fresh garnish that cuts through the richness with a pop of color.
8 oz medium pasta shells: The perfect shape to cradle the creamy sauce in every bite.
1 cup heavy cream: Creates a luxuriously smooth base for the cheesy garlic sauce.
1 cup shredded sharp cheddar cheese: Sharpness adds contrast to the creamy elements for a balanced taste.
½ cup grated Parmesan cheese: Adds a nutty, savory layer that deepens the flavor complexity.
½ tsp paprika: A mild warmth that works flawlessly alongside the Cajun seasoning.
½ tsp black pepper: Enhances the spice profile and complements the steak seasoning.
¼ cup reserved pasta water (optional): Helps loosen and perfect the silky texture of the sauce.

How to Make Cajun Steak Bites and Cheesy Garlic Shells Skillet

Step 1: Cook the Pasta Shells

Start by bringing a large pot of salted water to a boil. Cooking the pasta shells al dente guarantees the perfect bite—firm with just enough give to soak up all that creamy cheese sauce without becoming mushy. Reserve about a quarter cup of the pasta water before draining; this little trick helps you adjust your sauce’s consistency later on.

Step 2: Prepare and Season the Steak Bites

Pat your steak cubes dry with paper towels; removing moisture is critical to getting a good sear. Toss the cubes in Cajun seasoning, salt, and pepper, making sure every piece is coated evenly. This seasoning blend is what gives your steak bites that vibrant, smoky, and spicy personality that shines through every mouthful.

Step 3: Sear the Steak Bites

Heat a cast iron skillet over medium-high heat and add olive oil. Sear the steak bites in batches to avoid overcrowding—this ensures that each piece develops a gorgeous brown crust. Cook them for 2 to 3 minutes on each side. In the final minute of cooking, add butter and minced garlic to the skillet, tossing the steak bites through it to coat them in garlicky richness before removing them from the pan and setting aside.

Step 4: Build the Cheesy Garlic Sauce

Reduce the skillet heat to medium and add more butter along with minced garlic. Sauté the garlic for about a minute until fragrant and golden. Next, pour in the heavy cream, stirring constantly to release any flavorful browned bits stuck to the bottom from the steak. Let it simmer gently to thicken slightly.

Step 5: Add the Cheeses and Seasonings

Stir in the shredded cheddar, grated Parmesan, paprika, black pepper, and salt. Mix continuously until all the cheese melts smoothly into the cream, creating a luscious, velvety sauce. This is where that perfect balance of creamy, sharp, and smoky flavors comes together beautifully.

Step 6: Combine Pasta and Sauce

Toss the cooked pasta shells directly into the skillet with the cheese sauce. If the sauce feels too thick, stir in some of the reserved pasta water a little at a time until you reach your desired saucy consistency. The shells will soak up this heavenly sauce, making every bite pure comfort.

Step 7: Finish with Steak Bites and Garnish

Top the cheesy garlic shells with your warm, spiced Cajun steak bites. Sprinkle with fresh chopped parsley to add a vibrant green note and a fresh contrast that enhances the overall presentation. Serve right from the skillet for that cozy, home-cooked feel that’s impossible not to love.

Garnishes

Besides the fresh parsley, feel free to sprinkle a light dusting of extra Parmesan or a pinch of smoked paprika to elevate the colors and flavors. A squeeze of fresh lemon juice over the top can also brighten the dish and balance out the richness.

Side Dishes

This skillet meal shines on its own but pairs beautifully with crisp, fresh green salads, roasted vegetables like asparagus or Brussels sprouts, or even a light coleslaw to offer a crunchy contrast. Garlic bread is a classic side that’s guaranteed to be the perfect vehicle for mopping up any leftover sauce.

Creative Ways to Present

For a fun twist, try serving the Cajun Steak Bites and Cheesy Garlic Shells Skillet in mini cast iron skillets for a charming individual presentation at dinner parties. You can also layer the dish in clear bowls to showcase the colorful layers of golden steak, creamy cheese, and vibrant parsley, making it as visually inviting as it is delicious.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Because of the creamy sauce, the pasta may absorb some of the liquid, so it’s normal for the texture to become a bit thicker.

Freezing

While the steak bites and cheesy shell pasta are best enjoyed fresh, you can freeze leftovers in a freezer-safe container for up to 1 month. Be sure to thaw overnight in the refrigerator before reheating.

Reheating

To reheat, warm the skillet gently over low heat, adding a splash of milk or reserved pasta water to loosen the sauce and prevent it from drying out. Stir often to ensure even heating and maintain that creamy texture.

FAQs

Can I use a different cut of steak for this dish?

Absolutely! Sirloin and ribeye are preferred for their tenderness and flavor, but other cuts like strip steak or even tenderized flank steak can work well, just be mindful of cooking times to avoid overcooking.

Is it possible to make this dish gluten-free?

Yes! Simply swap out the medium pasta shells for gluten-free pasta shells or another similar gluten-free shape. The rest of the recipe remains the same, and the flavor will still be outstanding.

How spicy is the Cajun seasoning used?

Most store-bought Cajun seasoning has a moderate heat level with a delicious balance of herbs and spices. If you prefer it milder or spicier, you can adjust the amount or choose a blend that fits your heat preference.

Can I make the cheese sauce without heavy cream?

You can substitute heavy cream with half-and-half or whole milk for a lighter version, though the sauce will be less rich and may not thicken as much. Adding a small amount of flour or cornstarch can help thicken if needed.

What should I do if I don’t have a cast iron skillet?

No worries! A heavy-bottomed stainless steel skillet or non-stick pan works well too. Just be sure the pan gets hot enough to sear the steak properly and to develop that deep, caramelized flavor.
