What You’ll Need

• 500 g (1 lb 12 oz) beef sirloin, trimmed and cut into 1 cm (½‑inch) cubes: Sirloin is a fantastic choice for its balance of flavor and tenderness. Trimming away excess fat ensures a clean sear, and the ½-inch cubes provide the perfect bite-sized portion.
• 250 g (8 ½ oz) small pasta shells: Shell pasta, also known as conchiglie, is ideal for this dish because its shape beautifully cradles the creamy Alfredo sauce. Choose a high-quality pasta for the best texture.
• 2 tablespoons (30 ml) olive oil: We’re using olive oil for searing the steak. Its higher smoke point helps achieve a beautiful brown crust without burning.
• 3 tablespoons (45 g) unsalted butter, divided: Butter is essential for both flavor and richness in this recipe. We’ll use it for searing the garlic and creating the Alfredo sauce. Using unsalted butter allows you to control the overall saltiness of the dish.
• 2 cloves garlic, minced: Freshly minced garlic provides an aromatic base for the Alfredo sauce. Don’t skimp – garlic is key!
• 200 ml (¾ cup) heavy cream: Heavy cream is the foundation of a truly decadent Alfredo sauce. Its high fat content creates a luxuriously smooth and creamy texture.
• 30 g (¼ cup) grated Parmesan cheese: Real Parmesan cheese (Parmigiano-Reggiano is best!) adds a salty, umami depth to the sauce. Freshly grated is always preferred over pre-grated.
• ½ teaspoon (2 g) dried oregano: A touch of dried oregano provides a subtle herbaceous note that complements the beef and garlic.
• ½ teaspoon (2 g) freshly ground black pepper: Freshly ground black pepper adds a warm spice and enhances the other flavors.
• 1 teaspoon (5 g) kosher salt: Kosher salt is used to season the steak and the pasta water. Its larger crystals distribute flavor evenly.
• 1 tablespoon (15 ml) vegetable broth: Vegetable broth is used to deglaze the pan after searing the steak, lifting up all those flavorful browned bits (fond) from the bottom.
• Fresh parsley, chopped, about 2 tablespoons (8 g): Fresh parsley adds a bright, fresh garnish and a pop of color.
• Zest of ½ lemon: Lemon zest provides a bright, citrusy contrast to the richness of the Alfredo sauce.

Ingredient Substitutions

Don’t have everything on hand? Here are a few simple substitutions you can make:

• Beef Sirloin: You can substitute with other tender cuts of beef like ribeye or tenderloin, though cooking times may vary.
• Heavy Cream: In a pinch, you can use half-and-half, but the sauce won’t be as thick or rich.
• Parmesan Cheese: Pecorino Romano cheese can be used as a substitute for Parmesan, offering a similar salty and sharp flavor.
• Pasta Shells: Other small pasta shapes like cavatappi or rotini will also work well.

Detailed Step-by-Step Instructions

1. Cook the Pasta: Bring a large pot of heavily salted water to a rolling boil. Adding enough salt is crucial – it seasons the pasta from the inside out. Add the small pasta shells and cook for 9-11 minutes, or until al dente. ‘Al dente’ means ‘to the tooth’ in Italian, indicating the pasta should be firm to the bite. Before draining, reserve ½ cup of the pasta water. This starchy water is liquid gold for adjusting the sauce consistency later. Drain the pasta in a colander.
2. Season the Steak: While the pasta is cooking, generously season the beef cubes with kosher salt and freshly ground black pepper. Ensure each piece is evenly coated. Don’t be shy with the seasoning; steak benefits from a robust flavor profile.
3. Sear the Steak: Heat the olive oil in a heavy-bottomed skillet (cast iron is ideal) over medium-high heat. The skillet needs to be hot to achieve a good sear. Add the beef cubes in a single layer, avoiding overcrowding. Sear for 2-3 minutes per side, without moving them, until a deep brown crust forms. This crust is where a lot of the flavor develops. Flip and sear the other side for another 2 minutes. Transfer the seared steak to a plate and let it rest for 2 minutes. Resting allows the juices to redistribute, resulting in more tender steak bites.
4. Sauté the Garlic: Reduce the heat to medium. Add 1 tablespoon of butter to the same skillet. Once melted, add the minced garlic and sauté for about 30 seconds, until fragrant. Be careful not to brown the garlic, as it can become bitter.
5. Deglaze the Pan: Pour in the vegetable broth, scraping the bottom of the skillet with a wooden spoon to release any browned bits (fond). This fond is packed with flavor. Let the broth reduce by half, about 1 minute.
6. Create the Alfredo Sauce: Pour in the heavy cream and bring to a gentle simmer. Cook for 2-3 minutes, allowing the cream to slightly thicken. Whisk in the remaining 2 tablespoons of butter until fully incorporated, creating a rich and emulsified sauce.
7. Add Parmesan and Oregano: Add the grated Parmesan cheese and dried oregano to the sauce, stirring constantly until the cheese melts and the sauce thickens further. If the sauce becomes too thick, gradually add a splash of the reserved pasta water until it reaches your desired consistency.
8. Combine and Heat Through: Toss the cooked shells into the Alfredo sauce, ensuring they are evenly coated. Gently fold in the rested steak bites and heat everything together for 1-2 minutes, just until the steak is warmed through.
9. Final Seasoning and Serve: Taste the dish and season with a pinch more salt and pepper if needed. Plate immediately, swirling a thin line of sauce around the edge, mounding the pasta and steak mixture in the center, drizzling with a small stream of melted butter, and garnishing with chopped parsley and lemon zest.

The Science of a Perfect Sear

Achieving a beautiful sear on the steak bites isn’t just about aesthetics; it’s about the Maillard reaction. This chemical reaction between amino acids and reducing sugars requires high heat and a dry surface. That’s why patting the steak dry before seasoning is so important. The sear creates complex flavor compounds that elevate the entire dish. The resting period after searing is also vital, allowing the muscle fibers to relax and reabsorb juices, resulting in a more tender bite.

Why Shell Pasta?

The shape of shell pasta (conchiglie) isn’t accidental. These little shells are designed to capture and hold the creamy Alfredo sauce, ensuring every bite is bursting with flavor. The ridges and curves provide ample surface area for the sauce to cling to, creating a more satisfying and flavorful experience compared to smoother pasta shapes.

Alfredo Sauce: Beyond the Basics

A truly exceptional Alfredo sauce relies on emulsification – the process of combining two liquids that normally don’t mix (like fat and water). The constant whisking and the addition of butter help to create a stable emulsion, resulting in a silky smooth and luxurious sauce. Using high-quality Parmesan cheese is also key; its umami-rich flavor is fundamental to the sauce’s depth.

Tips for a Creamy, Non-Separating Alfredo

Sometimes Alfredo sauce can ‘break’ – meaning the fat separates from the liquid. To prevent this, ensure your heat is gentle, and don’t boil the sauce. Adding the Parmesan gradually, while whisking constantly, also helps maintain the emulsion. If your sauce does separate, a splash of cold pasta water can sometimes bring it back together.

Frequently Asked Questions

Can I use a different cut of steak?

While sirloin is recommended for its balance of flavor and tenderness, you can substitute with ribeye or New York strip for a richer flavor. Adjust cooking time accordingly.

Can I make this dish ahead of time?

It’s best served immediately. However, you can cook the pasta and steak separately and store them in the refrigerator. Reheat and combine with the sauce just before serving.

Is it possible to make a lighter Alfredo sauce?

You can reduce the amount of heavy cream and substitute some with milk, but the sauce won’t be as rich. Using a lower-fat Parmesan cheese will also reduce the overall fat content.
