This mouthwatering combo of tender steak bites in garlic butter paired with cheesy tortellini in smooth alfredo sauce delivers a fancy dinner that's ready in half an hour. The buttery garlic flavors the perfectly cooked steak while the homemade alfredo wraps around plump cheese-filled pasta pockets, creating a super satisfying meal that tastes like it took all day.
I came up with this dish when my husband's parents showed up unannounced one night. With barely any time and knowing they'd expect something good, this meal saved the day and has turned into our favorite special occasion dinner since then.
What You'll Need
- 1½ lbs steak bites: grab sirloin or ribeye for the juiciest results; look for pieces with good fat marbling for extra flavor
- 3 tablespoons butter: helps brown the steak; adds a rich taste and creates that gorgeous golden outside
- 3 garlic cloves, minced: nothing beats the smell and flavor of real garlic compared to the stuff in jars
- 1 package cheese tortellini (20 oz): the refrigerated kind cooks quicker but you can use frozen too
- 2 tablespoons butter: forms the foundation of your creamy alfredo sauce
- 2 cups heavy cream: gives that genuine alfredo thickness everyone loves
- 1½ cups grated Parmesan cheese: grate it yourself for better melting than the pre-shredded kind
- Salt and black pepper to taste: these basic seasonings bring out all the other tastes in the dish
How To Make It
- Cook the Tortellini:
- Get a big pot of really salty water boiling. The water should taste as salty as the ocean to make the pasta taste good from the inside out. Toss in your cheese tortellini and let them cook for what the package says (usually 7-9 minutes for the refrigerated kind). Give them a stir now and then so they don't stick together. You'll know they're done when they float up and feel tender but still a bit firm when you bite them. Drain them well but don't rinse them off. The starchy coating helps the sauce stick better. You can drizzle a tiny bit of olive oil on them to keep them from clumping while you work on the rest.
- Sear the Steak Bites:
- Get a big, heavy pan super hot. You should feel heat coming up when you put your hand above it. Drop in the butter and let it melt completely until it starts bubbling slightly. Toss in your minced garlic and cook for about 30 seconds until it smells amazing. Don't let it burn or it'll taste bitter and ruin everything. Add your steak pieces in a single layer so each one touches the hot pan directly. Don't crowd them or they'll steam instead of getting that nice crust. You might need to cook them in batches. Let each side cook for 2-3 minutes until they get a nice brown crust but stay a little pink inside for juiciness. Add plenty of salt while cooking to bring out the flavor. Move the cooked steak to a plate but leave all the tasty bits and garlic butter in the pan.
- Prepare Alfredo Sauce:
- Using that same pan with all the flavorful stuff left in it, melt the extra butter over medium heat. Pour in the heavy cream and let it warm up until it's bubbling gently around the edges. Don't let it boil hard. Stir it often with a wooden spoon so it doesn't burn. Add the Parmesan cheese bit by bit in three parts, making sure each part melts completely before adding more. This keeps it from getting lumpy and makes it super smooth. Add salt and fresh ground pepper to taste as you go. Let the sauce bubble gently for 5-7 minutes, stirring now and then, until it coats the back of a spoon. Remember the sauce will get thicker as it cools, so take it off the heat when it seems a little thinner than you want it.
- Assemble the Dish:
- Carefully mix the cooked tortellini into the alfredo sauce using a soft spatula so you don't break the pasta. Make sure every piece gets covered in the creamy sauce. Let them cook together for just a minute or two so the pasta soaks up some of the flavor. Keep it a bit more saucy than you think you need since the pasta will keep absorbing the sauce.
- Plate and Finish:
- Scoop the creamy tortellini onto warm plates, making a little bed for the steak. Place the seared steak bites on top, nestling them slightly into the sauce. Pour any leftover garlic butter from cooking the steak over everything for an extra burst of flavor. This last touch makes the whole dish shine with a gorgeous richness.

Helpful Tips
The secret to making this dish amazing is using all those browned bits from the steak to start your alfredo sauce. When I figured this trick out, it totally changed how the sauce tastes. My husband now asks for this every birthday and says it's way better than what he gets at restaurants.

Common Questions
- → What type of steak works best for this dish?
Go for sirloin or ribeye since they're tender and full of flavor. But don't worry if you've got something else like strip steak that sears quickly. That'll do the job too.
- → Can I use store-bought Alfredo sauce?
Sure thing. Grabbing pre-made sauce saves you time. But whipping up your own gives the meal more depth and richness if you can spare a few extra minutes.
- → How can I prevent the tortellini from sticking together?
Just drizzle and mix a bit of olive oil through your drained tortellini. This simple trick stops them from clumping up while you finish making everything else.
- → What's the best way to achieve a good sear on the steak?
Let your steak sit out to reach room temp first. Don't crowd too many pieces in your pan at once. Cook on medium-high heat and don't flip them too soon. Give them time to form that tasty golden crust.
- → Can I make this dish ahead of time?
You can prep the parts separately ahead of time, but it's way better to put everything together right before eating. This keeps the steak juicy and the sauce nice and creamy.
