Creating Shrimp Tortellini with Garlic Sauce is a simple process if you follow these detailed steps:

1. Cook Tortellini: In a large pot of boiling salted water, cook the tortellini according to package instructions. Drain and set aside.
2. Sauté Shrimp: In a large skillet over medium heat, melt 2 tablespoons of butter. Add the shrimp and season with salt and pepper. Cook until they turn pink, about 2-3 minutes per side. Remove shrimp and set aside.
3. Make Garlic Sauce: In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add the minced garlic and sauté for 1-2 minutes until fragrant.
4. Add Cream: Slowly pour in the heavy cream, stirring it into the garlic mixture. Let it simmer for about 3 minutes, allowing it to thicken slightly.
5. Combine Ingredients: Stir in the cooked tortellini and shrimp, mixing until everything is well coated with the sauce.
6. Add Spinach: If using, add the fresh spinach to the skillet and cook until wilted, about 1-2 minutes.
7. Finish with Cheese: Stir in the Parmesan cheese, allowing it to melt and enrich the sauce. Adjust seasoning with salt and pepper if needed.
8. Serve Immediately: Once everything is well combined and heated through, remove from heat.

These straightforward steps ensure your Shrimp Tortellini with Garlic Sauce comes out perfectly each time.
