Ingredients:
- 2 whole ribeye steaks, cut into cubes
- 2 tablespoons Cajun seasoning (for steak)
- Melted beef tallow as needed (for steak)
- 1 pound large shrimp, peeled and deveined
- 2 tablespoons Cajun seasoning (for shrimp)
- Melted beef tallow as needed (for shrimp)
- 16 ounces penne pasta
- 1/2 cup unsalted butter, room temperature
- 1/2 cup freshly grated Romano cheese
- 1/2 cup freshly grated Parmesan cheese
- Fresh chives, chopped for garnish
Preparing the Steak and Shrimp
The first step to an incredible Steak and Shrimp Alfredo is to get our star proteins ready. We’re going to season both the steak and the shrimp separately to ensure each bite is bursting with flavor. Take your cubed ribeye steaks and place them in a medium bowl. Sprinkle generously with 2 tablespoons of Cajun seasoning. Toss everything together thoroughly to make sure every single piece of steak is coated. This seasoning blend is key to that little kick and savory depth that makes this dish so special.
Next, in a separate bowl, prepare your shrimp. Add the peeled and deveined large shrimp to this bowl. Sprinkle them with the other 2 tablespoons of Cajun seasoning. Again, toss gently to ensure an even coating. It’s important to keep them separate at this stage because they will cook at different rates, and we want to maximize their individual flavors.
Cooking the Steak
Now it’s time to cook the steak to perfection. Heat a large skillet or cast-iron pan over medium-high heat. Once the pan is smoking hot, add a generous amount of melted beef tallow. You’ll know it’s ready when it shimmers. Carefully add the seasoned steak cubes to the hot tallow in a single layer. Avoid overcrowding the pan; you may need to cook the steak in batches to achieve a beautiful sear. Overcrowding will steam the meat instead of searing it, resulting in a less desirable texture.
Sear the steak for about 2-3 minutes per side, depending on your desired level of doneness. For medium-rare, aim for that quick sear. We want a beautiful crust on the outside and a tender, juicy interior. Once seared to your liking, remove the steak from the pan and set it aside on a plate. Tent it loosely with foil to keep it warm and allow the juices to redistribute. This resting period is crucial for succulent steak.
Cooking the Shrimp
With the steak resting, we’ll move on to the shrimp. Make sure your skillet still has some residual heat from the steak. If needed, add a little more melted beef tallow to the pan. Return the pan to medium-high heat. Add the seasoned shrimp to the hot skillet. Be careful not to overcrowd the pan, just like with the steak.
Cook the shrimp for approximately 1-2 minutes per side. Shrimp cook very quickly, and we want them to turn pink and opaque, with a slight curl. Overcooked shrimp can become rubbery, so keep a close eye on them. Once they are perfectly cooked, remove them from the pan and add them to the plate with the resting steak.
Cooking the Penne Pasta
While the steak and shrimp are resting and finishing, let’s get our pasta cooking. Bring a large pot of generously salted water to a rolling boil over high heat. Add the 16 ounces of penne pasta to the boiling water. Stir the pasta immediately to prevent it from sticking together. Cook the penne according to the package directions until it is al dente – tender but still firm to the bite. It’s important not to overcook the pasta, as it will continue to cook slightly when mixed with the sauce.
Once the pasta is cooked to your liking, reserve about 1 cup of the starchy pasta water before draining. This reserved water is liquid gold for creating a luscious, emulsified sauce. Drain the remaining pasta and set it aside.
Creating the Creamy Alfredo Sauce
Now for the magic – the Alfredo sauce! In the same pot you used for the pasta (or a separate large skillet if you prefer), melt the 1/2 cup of unsalted butter over medium heat. Once the butter is melted and slightly foamy, add both the 1/2 cup of freshly grated Romano cheese and the 1/2 cup of freshly grated Parmesan cheese. Whisk them into the butter until a smooth, creamy sauce begins to form.
Gradually whisk in about 1/2 cup of the reserved pasta water. Continue to whisk constantly, adding more pasta water a little at a time, until the sauce reaches your desired consistency. The starch from the pasta water will help the cheese and butter emulsify, creating a rich, glossy sauce that coats the pasta beautifully. Season with salt and pepper to taste if you feel it needs it, but remember the Cajun seasoning on the proteins is already quite flavorful.
Assembling the Steak and Shrimp Alfredo
The final, glorious step is assembly. Add the drained penne pasta directly into the pot or skillet with the warm Alfredo sauce. Gently toss the pasta to coat every piece evenly with the creamy sauce. If the sauce seems too thick, add another splash of the reserved pasta water until you achieve your desired consistency.
Once the pasta is well-coated, add the cooked steak cubes and shrimp back into the pot with the pasta and sauce. Gently fold them in, ensuring they are warmed through by the sauce. Be careful not to overmix, which can break down the steak or shrimp. Serve this magnificent Steak and Shrimp Alfredo immediately in large bowls. Garnish generously with freshly chopped chives for a pop of color and fresh flavor. The vibrant green of the chives against the creamy pasta and rich proteins is a beautiful finishing touch.

Frequently Asked Questions:
What kind of steak is best for Steak and Shrimp Alfredo?
For this recipe, a tender cut like sirloin, New York strip, or even a filet mignon works wonderfully. The key is to choose a steak that cooks relatively quickly and is flavorful on its own.
