Ingredients

Full recipe card is below.

Sirloin steak – Tender and juicy, perfect for quick searing
Cheese tortellini – Adds a rich, cheesy bite that pairs with the Alfredo beautifully
Butter – For that golden, luxurious sear and sauce
Olive oil – Helps the butter cook without burning
Fresh garlic – Brings that irresistible savory aroma
Heavy cream – Makes the Alfredo sauce rich and silky
Parmesan cheese – Salty, nutty, and melts right into the sauce
Parsley – A fresh pop of color and brightness
Salt and pepper – Essential for seasoning both steak and sauce
Crushed red pepper flakes (optional) – A little heat if you like a kick

How to Make It

1. Prep Your Steak and Tortellini

Cut your steak into bite-sized cubes—try to keep them even so they cook at the same speed. Meanwhile, boil your cheese tortellini according to package directions. Drain and set aside. A little drizzle of olive oil keeps them from sticking together.

2. Sear the Steak Bites

Heat a splash of olive oil and a pat of butter in a large skillet over medium-high heat. Toss in the steak bites, sprinkle generously with salt and pepper, and sear until they’re golden-brown and just barely pink inside. It only takes a few minutes! Remove them from the pan and set aside.

Chef tip: Don’t overcrowd the pan; give those bites some breathing room to get that crusty, caramelized exterior.

3. Make the Creamy Alfredo Sauce

In the same skillet, lower the heat and add a little more butter and the minced garlic. Let it get nice and fragrant, about 30 seconds. Then pour in your heavy cream, stirring to catch all those golden steak bits from the bottom. Let it simmer for a couple minutes until slightly thickened, then stir in your Parmesan until it melts like a dream.

4. Bring It All Together

Add your cooked tortellini to the sauce and toss gently to coat. Then slide those buttery steak bites back into the pan, along with any juices. Stir everything together until heated through. Sprinkle with parsley and a little crushed red pepper if you want some zing!

Pro Tips for Success

Pat your steak dry before searing — moisture is the enemy of a good crust.
Use freshly grated Parmesan — it melts so much better than the pre-shredded stuff.
Don’t overcook your steak bites — they’ll keep cooking slightly once they hit the hot Alfredo sauce.
Keep your heat medium-low when making the sauce to avoid breaking the cream.
Taste as you go — seasoning at every stage builds layers of flavor.

Flavor Variations

Swap tortellini for fettuccine to create a fun spin on classic steak fettuccine Alfredo.
Add sautéed mushrooms or spinach for an extra veggie punch.
Stir a little pesto into the Alfredo for a herby twist.
Use shrimp instead of steak for a surf-and-turf version.

Serving Suggestions

Serve with warm, crusty garlic bread to sop up all that dreamy sauce.
A crisp Caesar salad balances the richness perfectly.
A bold red wine like Cabernet Sauvignon makes this meal extra special.

Make-Ahead & Storage

You can cook the steak bites and make the sauce ahead of time, then refrigerate separately. Reheat gently and toss together right before serving to keep everything tender and creamy.

Leftovers

Leftovers make a fabulous lunch the next day! Add a splash of cream or milk when reheating to refresh the sauce. You can also tuck them into a hoagie roll for an epic steak Alfredo sandwich.

Freezing

Not the best candidate for freezing, since creamy sauces can break when thawed. It’s best enjoyed fresh or within a couple of days from the fridge.

Reheating

Gently reheat on the stovetop over low heat, adding a touch of cream if needed. The microwave works too — just use 50% power and stir often to keep it creamy.

FAQs

Can I use a different cut of steak?
Absolutely! Ribeye, New York strip, or filet mignon would all work beautifully.

Can I make this without tortellini?
Yes, you can swap in fettuccine, penne, or even gnocchi!

Is it spicy with the red pepper flakes?
Nope, just a little warmth. Skip it if you’re sensitive, or add extra if you love a kick!

Can I double the sauce?
Oh yes — especially if you’re swapping in pasta like for a steak and fettuccine Alfredo vibe. Double it and thank me later!
