Cook the Tortellini: Bring a pot of salted water to a boil, add tortellini, and cook according to package instructions, about 3-5 minutes. Drain and set aside.

Sear the Steak: Heat olive oil in a skillet over medium-high heat. Season steak with salt, pepper, garlic powder, and smoked paprika. Sear for 3-5 minutes per side until browned. Rest steak.

Prepare the Sauce Base: Lower heat to medium-low, add butter to skillet, melt, and stir in garlic. Sauté for 1 minute until fragrant.

Create the Cream Sauce: Pour in heavy cream and milk, stir, and bring to a gentle simmer for 3-4 minutes to thicken.

Incorporate the Cheese: Gradually add Parmesan cheese, stirring until melted and combined. Adjust seasoning as needed.

Combine Everything: Return steak to the skillet (sliced) and add cooked tortellini. Toss together in sauce for 2 minutes.

Garnish and Serve: Transfer to plates, sprinkle with parsley, red pepper flakes, and cracked pepper. Serve immediately.
