Ingredients for this recipe
For the Steak Bites:
- 1 lb sirloin steak, cut into bite-sized cubes
- 1 tbsp olive oil
- 1 tbsp butter
- Salt and black pepper to taste
- 1 tsp garlic powder
- Optional: chopped fresh parsley for garnish
For the Shell Pasta and Garlic Butter Alfredo Sauce:
- 12 oz medium shell pasta
- 2 tbsp butter
- 4 garlic cloves, minced
- 1 1/2 cups heavy cream
- 1 cup grated Parmesan cheese
- 1/4 tsp black pepper
- Salt to taste
- Optional: pinch of nutmeg for added warmth

Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil. Add the shell pasta and cook according to package instructions until al dente. Drain and set aside.
Step 2: Prepare the Steak Bites
While the pasta cooks, pat the steak cubes dry with paper towels. Season them evenly with salt, pepper, and garlic powder.
In a large skillet over medium-high heat, add the olive oil and butter. Once hot, sear the steak bites for about 1-2 minutes per side until browned and cooked to your desired doneness. Remove from the skillet and set aside, covering them to keep warm.
Step 3: Make the Garlic Butter Alfredo Sauce
In the same skillet, lower the heat to medium. Add butter and minced garlic, sautéing until fragrant (about 1 minute).
Pour in the heavy cream and stir. Bring to a gentle simmer and cook for 3-4 minutes, allowing the sauce to thicken slightly.
Add in the Parmesan cheese and stir until melted and smooth. Season with black pepper, salt to taste, and nutmeg if using.
Step 4: Combine Pasta and Sauce
Add the cooked shell pasta to the Alfredo sauce. Toss well to ensure each shell is coated in the creamy mixture.
Step 5: Assemble and Serve
Plate the pasta in bowls or on a serving dish. Top generously with the seared steak bites. Garnish with chopped parsley if desired.
Serve immediately while hot and creamy!
Frequently Asked Questions
Can I use a different cut of steak?
Yes, ribeye, New York strip, or tenderloin work great too. Just aim for well-marbled cuts for the juiciest bites.
What pasta shapes work best if I don’t have shells?
Try penne, rotini, or orecchiette—any shape that holds sauce well is a solid substitute.
Can I make the Alfredo sauce lighter?
You can swap half-and-half for heavy cream, or use whole milk with a little flour to thicken. The sauce will be less rich but still flavorful.
How do I avoid overcooking the steak?
Make sure your pan is very hot before adding the steak and don’t overcrowd it. Sear quickly, turning just once.
Is this recipe spicy?
No, but you can add crushed red pepper flakes or a dash of cayenne to the Alfredo sauce for a spicy kick.
Can I add vegetables to this dish?
Absolutely. Sautéed mushrooms, spinach, or steamed broccoli all complement the steak and Alfredo flavors beautifully.
