Step 1: Brown the Beef

• Heat olive oil in a large skillet over medium-high heat.
• Add the cubed beef, seasoning it with salt and freshly ground black pepper. Cook the beef for 5-7 minutes, or until it is browned on all sides and cooked through. The browning of the beef adds a deep, savory flavor to the dish.
• Remove the beef from the skillet and set aside.

Step 2: Sauté the Aromatics

• In the same skillet (do not clean it to retain the beef flavors), add the diced onion and minced garlic. Sauté over medium heat for about 3 minutes, until the onions become translucent and the garlic releases its fragrance. This will build the aromatic base for the creamy sauce.

Step 3: Simmer with Cream

• Return the browned beef to the skillet.
• Pour in the heavy cream, stirring to combine with the onions and garlic.
• Bring the mixture to a gentle simmer, and then add dried basil and half of the grated Parmesan cheese. Let it simmer for 4-5 minutes, allowing the sauce to thicken slightly and the flavors to meld together.

Step 4: Combine with Tortellini

• Once the sauce has thickened, toss the cooked tortellini into the skillet. Stir everything together until the tortellini is well coated with the creamy, cheesy sauce.
• Season with additional salt and pepper to taste if needed.

Step 5: Serve Garnished

• Serve the beef and tortellini hot, topped with the remaining grated Parmesan cheese and a sprinkle of fresh chopped parsley for a pop of color and added flavor.
