Step 1: Cook the Tortellini - Bring a large pot of salted water to a rolling boil. Add the cheese tortellini and cook for 3-5 minutes until they float and are al dente. Drain and set aside.

Step 2: Season and Sear the Steak - Heat olive oil in a large skillet over medium-high heat. Season the steak with salt, pepper, garlic powder, and smoked paprika. Sear for 3-5 minutes per side to desired doneness. Transfer to a plate to rest.

Step 3: Prepare Garlic Cream Sauce - In the same skillet, melt butter over medium heat. Add minced garlic; sauté for 1 minute until fragrant.

Step 4: Create Cream Sauce - Pour in heavy cream and whole milk, stirring continuously. Allow to simmer for 3-4 minutes until slightly thickened.

Step 5: Incorporate the Cheese - Gradually whisk in parmesan cheese until melted and smooth. Keep on low heat to thicken further.

Step 6: Combine Ingredients - Return sliced steak and cooked tortellini to the skillet. Toss gently for 2 minutes, ensuring everything is well-coated in sauce.

Step 7: Garnish and Serve - Sprinkle chopped parsley, black pepper, and red pepper flakes over the dish. Serve immediately.
