What You’ll Need
- 500g (1.1lb) Beef Sirloin, Cubed: We recommend sirloin for its tenderness and flavor, but a ribeye or tenderloin would also work beautifully. Ensure the beef is trimmed of excess fat and cut into roughly 2cm (¾-inch) cubes for even cooking. Opting for halal-certified beef ensures it meets specific dietary requirements.
- 2 Tbsp (30ml) Olive Oil: Essential for searing the steak, olive oil provides a healthy fat and helps develop a beautiful crust. Use a good quality extra virgin olive oil for the best flavor.
- 2 tsp (10g) Cajun Seasoning: The heart of the Cajun flavor! Choose a classic blend that includes paprika, cayenne pepper, garlic powder, onion powder, and other aromatic spices. Adjust the amount to your preferred level of heat.
- 1 tsp (5g) Smoked Paprika: Adds a delightful smoky depth to the steak, complementing the Cajun spices. Sweet or hot smoked paprika can be used depending on your preference.
- ½ tsp (2.5g) Ground Cumin: While optional, a touch of cumin enhances the savory notes and adds a subtle complexity to the spice rub.
- Salt and Freshly Ground Black Pepper: To taste, for seasoning the steak and sauce. Freshly ground pepper provides a more robust flavor.
- 250g (9oz) Small Shell Pasta (Conchiglie): The ‘shells’ are perfect for capturing the creamy sauce. Cooking the pasta ‘al dente’ – firm to the bite – ensures it holds its shape and texture in the skillet.
- 3 Tbsp (45g) Unsalted Butter, Divided: Butter adds richness and a glossy finish to the sauce. Using unsalted butter allows you to control the overall saltiness of the dish.
- 4 Cloves Garlic, Minced: The aromatic base of the cheese sauce. Freshly minced garlic provides the most potent flavor.
- ½ cup (120ml) Heavy Cream: Creates a luxuriously creamy sauce. You can substitute with half-and-half for a lighter version, but the sauce won’t be as rich.
- 1 cup (100g) Shredded Cheddar Cheese: Provides a sharp, classic cheese flavor. Use a good quality cheddar for the best melt and taste. Halal-certified cheddar is available for those with dietary needs.
- ½ cup (50g) Shredded Mozzarella Cheese: Adds a stretchy, melty texture to the sauce.
- 1 Tbsp (15ml) Dijon Mustard: Adds a tangy complexity to the sauce, balancing the richness of the cheese and cream. Ensure it is alcohol-free if needed.
- ¼ cup (15g) Grated Parmesan Cheese: Contributes a savory, umami flavor to the sauce.
- 2 Tbsp (30ml) Fresh Lemon Juice: Brightens the sauce and cuts through the richness, adding a refreshing contrast.
- 2 Tbsp (8g) Chopped Fresh Parsley: A vibrant garnish that adds a fresh, herbaceous note.
- Pinch of Dried Lavender Buds: A subtle, unexpected twist that adds a floral aroma and flavor. Use sparingly, as lavender can be overpowering.
- Handful of Edible Microgreens: Adds a pop of color and a delicate, fresh flavor.
Let’s Get Cooking: A Step-by-Step Guide
- Prepare the Steak: Begin by patting the beef cubes completely dry with paper towels. This is crucial for achieving a good sear. In a bowl, combine the Cajun seasoning, smoked paprika, cumin (if using), salt, and pepper. Toss the beef cubes thoroughly with this spice blend, ensuring each piece is well coated. Allow the seasoned steak to rest for at least 10 minutes. This resting period allows the flavors to penetrate the meat, resulting in a more flavorful final dish.
- Sear the Steak: Heat 1 tablespoon of olive oil in a large, heavy-bottomed cast-iron skillet over medium-high heat. The skillet should be shimmering hot before adding the steak. Add the seasoned steak bites in a single layer, avoiding overcrowding the pan. Sear for 2 minutes without disturbing them, allowing a beautiful crust to form. Flip the steak bites and sear for another 2 minutes, aiming for a browned exterior and a slightly pink interior. Transfer the seared steak to a plate, cover loosely with foil, and set aside to keep warm.
- Cook the Shell Pasta: While the steak rests, bring a large pot of salted water to a rolling boil. Add the small shell pasta (conchiglie) and cook according to package directions, usually 9-10 minutes, until al dente – firm to the bite. Drain the pasta, reserving about ½ cup of the pasta water. This starchy water will be invaluable for adjusting the sauce consistency later. Set the drained pasta aside.
- Create the Garlic Base: Return the cast-iron skillet to medium heat. Add the remaining 1 tablespoon of olive oil and then the 3 tablespoons of butter. Once the butter is melted and shimmering, add the minced garlic. Sauté for just 30 seconds, until fragrant. Be careful not to brown the garlic, as burnt garlic can become bitter.
- Build the Cheesy Sauce: Pour in the heavy cream, Dijon mustard, and lemon juice into the skillet with the garlic-infused butter. Simmer for 2 minutes, scraping the bottom of the skillet to deglaze and incorporate any browned bits (fond) – this is where a lot of flavor resides! Reduce the heat to low and gradually whisk in the shredded cheddar, mozzarella, and Parmesan cheeses, one handful at a time, until fully melted and the sauce is smooth and coats the back of a spoon.
- Combine Pasta and Sauce: Add the cooked shell pasta to the cheesy sauce, tossing gently to coat each shell evenly. If the sauce appears too thick, add the reserved pasta water, one tablespoon at a time, until you achieve a silky, luscious consistency.
- Finish and Serve: Return the seared steak bites to the skillet, nestling them among the cheesy shells. Toss gently to combine and warm the steak through for about 1 minute. Remove the skillet from the heat and stir in the remaining 2 tablespoons of butter for a glossy finish. Taste and adjust the seasoning with salt, pepper, or a squeeze of extra lemon juice, if needed. Plate immediately, garnishing with chopped parsley, a pinch of dried lavender buds, and a scattering of microgreens.
Why Cast Iron is Key
Using a cast-iron skillet isn’t just about tradition; it’s about superior heat retention and even cooking. The cast iron gets incredibly hot, creating a fantastic sear on the steak, and then holds that heat to keep the entire dish warm. The skillet also contributes to the development of flavorful fond – those browned bits on the bottom of the pan – which add depth and complexity to the sauce.
The Cajun Spice Blend: A Flavor Profile
Cajun seasoning is a vibrant blend of spices that brings a delightful kick to this dish. Typically, it includes paprika, cayenne pepper, garlic powder, onion powder, oregano, thyme, and black pepper. The smoked paprika adds a subtle smoky depth that complements the steak beautifully. Feel free to adjust the amount of Cajun seasoning to your preference – if you like it spicier, add a pinch of cayenne pepper!

Lavender’s Unexpected Touch
The addition of a pinch of dried lavender buds might seem unusual, but it adds a subtle floral aroma and a unique complexity to the dish. Lavender pairs surprisingly well with savory flavors, especially those with a bit of spice. Use it sparingly, as a little goes a long way. It’s a secret ingredient that elevates this Cajun Steak Bites and Cheesy Garlic Shells Skillet to something truly special.
Serving Suggestions & Wine Pairings
This Cajun Steak Bites and Cheesy Garlic Shells Skillet is a complete meal in itself, but it pairs wonderfully with a side of steamed green beans or a crisp garden salad. For a wine pairing, consider a medium-bodied red wine like a Merlot or a Cabernet Sauvignon. The fruit-forward notes of these wines will complement the spice of the Cajun seasoning and the richness of the cheesy sauce.
Frequently Asked Questions
Can I use a different type of steak?
Yes, you can! Ribeye or New York strip steak would also work well, but sirloin is a more affordable and readily available option. Adjust the searing time based on the thickness of the steak.
Can I make this dish ahead of time?
While best served immediately, you can prepare the steak and pasta separately ahead of time. Store them in the refrigerator and then combine them with the sauce just before serving.
Is this recipe gluten-free?
Yes, this recipe is naturally gluten-free, as long as your Dijon mustard and Cajun seasoning do not contain gluten.
