Step 1: Prepare the Tortellini

• Bring a large pot of salted water to a boil.
• Add the fresh tortellini and cook according to the package instructions, typically 2-3 minutes for fresh tortellini or 7-10 minutes for frozen.
• Once cooked, drain and set aside, reserving a small cup of pasta water.

Step 2: Cook the Beef

• Heat olive oil in a large skillet over medium-high heat.
• Add the thinly sliced beef (ribeye or sirloin) and cook until browned, about 3-4 minutes, stirring occasionally.
• Season with salt and pepper to taste.
• Once cooked, transfer the beef to a plate and set aside.

Step 3: Sauté the Vegetables

• In the same skillet, add a bit more olive oil if needed and sauté the sliced onion and red bell pepper (if using) over medium heat.
• Cook until the vegetables are soft and slightly caramelized, about 5-7 minutes.
• Add minced garlic and cook for another minute, until fragrant.

Step 4: Make the Provolone Sauce

• Reduce the heat to medium-low, and add the heavy cream to the pan with the sautéed vegetables.
• Stir to combine and bring the cream to a simmer.
• Gradually add the shredded provolone cheese, stirring constantly, until the cheese has melted and the sauce becomes smooth and creamy.
• For a thicker sauce, add a small amount of reserved pasta water or a little more cream.
• Stir in grated Parmesan cheese for extra richness and flavor.

Step 5: Combine the Beef, Tortellini, and Sauce

• Return the cooked beef to the pan with the sauce.
• Add the drained tortellini to the skillet, gently tossing to coat the pasta in the creamy sauce.
• If needed, add a little more reserved pasta water to achieve your desired sauce consistency.

Step 6: Garnish and Serve

• Taste the dish and adjust the seasoning with additional salt, pepper, or crushed red pepper flakes for some heat (optional).
• Add a tablespoon of butter for extra richness, if desired.
• Garnish with chopped fresh parsley for a burst of color and flavor.
• Serve hot and enjoy!

Tip: For a more indulgent touch, you can sprinkle extra shredded provolone or Parmesan cheese on top before serving.
