Roast the Garlic: Preheat your oven to 400°F (200°C). Cut the top off the garlic bulb, drizzle it with olive oil, wrap it in foil, and roast for about 30 minutes until aromatic.

Cook the Tortellini: Bring a large pot of water to a boil, season with salt, add the fresh tortellini, and cook as per package instructions for 3-5 minutes.

Sauté the Shrimp: In a skillet over medium heat, melt butter and add shrimp. Cook for 2-3 minutes until they turn pink and opaque.

Make the Sauce: Lower the heat, add heavy cream, roasted garlic, and Parmesan, stirring until creamy. Season with salt and pepper.

Combine It All: Fold the cooked tortellini into the sauce, ensuring everything is well coated. Serve hot, topped with extra Parmesan if desired.
