Ingredients for Steak Bites and Alfredo Shell Pasta
Don’t be intimidated by the ingredient list – it looks longer than it is! Most of these are pantry staples, and the steak portion is super simple. I always go for sirloin because it sears up beautifully without breaking the bank, but feel free to use your favorite cut! And for the pasta, shells are just perfect for catching all that creamy Alfredo goodness.
- 1 and 1/2 pounds sirloin steak, cut into 1-inch cubes
- 1 teaspoon salt (for the steak, don’t skip this!)
- 1 teaspoon black pepper (freshly ground makes a difference!)
- 1 teaspoon garlic powder (for seasoning the steak)
- 2 tablespoons olive oil (for that perfect sear)
- 2 tablespoons unsalted butter (for finishing the steak)
- 12 ounces medium shell pasta (the classic choice for a reason!)
- 1 teaspoon salt (for the pasta water – yes, it matters!)
- 3 tablespoons unsalted butter (this is for our luscious sauce)
- 4 cloves garlic, minced (fresh is best here!)
- 1 and 1/2 cups heavy cream (for ultimate creaminess)
- 1 cup grated parmesan cheese (get the good stuff, it’s worth it!)
- 1/2 teaspoon black pepper (for the sauce, adds a little kick)
- 1/2 teaspoon salt (for the sauce, to balance everything out)
- 2 tablespoons chopped fresh parsley (for a pop of color and freshness at the end)
Crafting Your Steak Bites and Alfredo Shell Pasta: Step-by-Step
Step 1: Let’s get that pasta going! Bring a big pot of water to a rolling boil. I always add a good teaspoon of salt to the water – it really seasons the pasta from the inside out. Cook your shell pasta according to the package directions until it’s perfectly al dente, meaning it still has a slight bite. Now, this is important: before you drain it, scoop out about half a cup of that starchy pasta water and set it aside. This magic liquid is going to help us get a super silky sauce later! Then, drain the pasta.
Step 2: While the pasta is cooking, let’s tackle these steak bites. Grab your cubed sirloin and give those pieces a good pat dry with paper towels. Seriously, this step is a game-changer for getting a beautiful sear, just like in my garlic butter steak bites recipe. Once they’re dry, season them generously all over with salt, pepper, and that handy garlic powder. Don’t be shy; you want them flavorful!
Step 3: Heat up your skillet over medium-high heat. Add the olive oil and let it get nice and shimmery. Carefully place the seasoned steak cubes into the hot pan in a single layer. You might need to do this in two batches if your pan isn’t huge, so you don’t crowd them – crowding steams the meat instead of searing it. Sear those beautiful bites for about 2 to 3 minutes on each side, just until they’re browned and gorgeous. Once they’re done, scoop them out of the skillet and set them aside on a plate.

Step 4: Lower the heat on your skillet to medium. Add the 2 tablespoons of butter. Once it’s melted and starting to bubble, toss in your minced garlic. Stir it around for about a minute until it smells amazing and super fragrant. Be careful not to burn the garlic; burnt garlic is just sad!
Step 5: Pour in the heavy cream. Bring it up to a gentle simmer, not a rolling boil. Let it bubble away gently for about 3 to 4 minutes, stirring occasionally, until it starts to thicken up just a bit. It should coat the back of a spoon nicely, similar to the way the sauce thickens in my one-pot chicken alfredo!
Step 6: Now for the cheesy magic! Stir in the grated Parmesan cheese, along with the salt and pepper for the sauce. Keep stirring until the cheese is completely melted and you have a wonderfully smooth and creamy Alfredo sauce. This is where the magic happens, folks!
Step 7: Add your drained shell pasta directly into the skillet with the Alfredo sauce. Toss everything together gently until every single shell is coated in that luscious sauce. If the sauce seems a little too thick for your liking, now’s the time to add a splash of that reserved pasta water. It makes the sauce so wonderfully silky and helps it cling to the pasta.
Step 8: It’s time to bring it all together! Return those seared steak bites to the skillet with the saucy pasta. Give it a gentle toss, making sure the steak bits get coated in that delicious sauce too. I just love seeing the steak and pasta mingling!

Step 9: Let everything simmer together for another minute or two, just until the steak bites are heated through and everything in the pan is nicely combined and warm. Don’t overcook the steak at this stage; we just want to marry the flavors.
Step 10: Garnish your beautiful creation with a sprinkle of fresh chopped parsley. It just adds that lovely pop of fresh color and flavor. Serve this amazing Steak Bites and Alfredo Shell Pasta immediately while it’s hot and creamy. Enjoy!
Serving Suggestions for Your Steak Bites and Alfredo Shell Pasta
This dish is so rich and satisfying on its own, but sometimes you just want a little something extra, right? Here are a few things I love to serve alongside it that really make the meal sing!

Storing and Reheating Your Steak Bites and Alfredo Shell Pasta
Got leftovers? Lucky you! I usually store any remaining Steak Bites and Alfredo Shell Pasta in an airtight container in the fridge for about 3 to 4 days. The sauce can thicken up a bit as it cools, which is totally normal. I also find that if I have a ton of leftovers, it’s easier to keep the steak bites separate from the pasta if I plan on reheating them for lunch the next day. It helps keep the steak from getting too soft.
When you’re ready to reheat, I recommend doing it on the stovetop or in the oven to get the best texture. Pop it into a skillet over medium-low heat, adding a tiny splash of milk or extra cream to loosen up that sauce. Stir it gently until everything is heated through. If you’re in a hurry, the microwave works too, just stir it halfway through to make sure it heats evenly! For more ideas for busy nights, definitely check out my other quick recipes!
Frequently Asked Questions about Steak Bites and Alfredo Shell Pasta
Can I use a different cut of steak for this recipe?
You absolutely can! While sirloin is my favorite for its great sear and flavor, a tenderloin or even a well-marbled ribeye would be delicious. Just be mindful that cooking times might vary slightly depending on the thickness and cut!
How can I make the Alfredo sauce creamier?
For an extra creamy sauce, try using a little more heavy cream or a splash more of the reserved pasta water. Sometimes, just letting it simmer for an extra minute or two while stirring can also help thicken it beautifully!
Can I make this recipe ahead of time?
You can definitely cook the steak bites and the pasta with sauce separately ahead of time and store them in the fridge. Then, just reheat them together gently on the stove or in the oven when you’re ready to serve, adding a little liquid to loosen the sauce if needed. It’s a great way to prep components!
