1-Step 1: Prepare Your Ingredients Before you begin cooking, it’s essential to prepare all your ingredients. Season the shrimp with all-purpose seasoning and set aside. Make sure your shrimp are peeled and deveined for convenience. This preparation step, often called mise en place, ensures a smooth cooking process without any last-minute scrambling. Measure out all your sauce ingredients, including the oil, wine, butter, garlic, flour, stock, cream cheese, heavy cream, dried basil, spinach, red pepper flakes, and Parmesan cheese. Having everything ready before you start cooking means you can focus entirely on technique rather than searching for ingredients mid-recipe.

2-Step 2: Start the Tortellini Bring a large pot of salted water to a boil. Once boiling, add the tortellini and cook according to package instructions, typically about 3-5 minutes for refrigerated varieties. You want the pasta al dente – tender but with a slight bite to the center. Overcooked tortellini will become mushy and won’t hold up well when combined with the sauce. Before draining, remember to save about 1/2 cup of the pasta water. This starchy liquid is a secret weapon that can help adjust the consistency of your sauce later. Drain the tortellini well and set aside while you prepare the shrimp and sauce.

3-Step 3: Sear the Shrimp Heat the oil in a large skillet over medium-high heat. Once hot, add half of the seasoned shrimp to the pan, being careful not to overcrowd. Sear for about 1-2 minutes per side until pink and just cooked through. Overcrowding the pan will cause the shrimp to steam rather than sear, resulting in less color and flavor. Remove the first batch of shrimp and set aside on a plate. Repeat with the second batch of shrimp. Once all shrimp are cooked, remove them from the pan and set aside. The shrimp will finish cooking when returned to the sauce later, so it’s okay to remove them when they’re just barely opaque in the center.

4-Step 4: Build the Sauce Foundation Reduce the heat to medium and deglaze the skillet with the white wine. Use a wooden spoon to scrape up any browned bits from the bottom of the pan – these add tremendous flavor to your sauce. Let the wine simmer for about 1-2 minutes to reduce slightly and cook off the alcohol. Add the butter and minced garlic to the pan. Cook for about 1 minute, stirring constantly until the garlic is fragrant but not browned. Burnt garlic will taste bitter and ruin the delicate balance of flavors. The butter should be melted and bubbling, coating the garlic evenly.

5-Step 5: Create the Creamy Base Sprinkle the flour over the garlic and butter mixture, stirring constantly to coat. Cook for about 1 minute to remove the raw flour taste. This creates a roux that will thicken your sauce without becoming gummy or lumpy. Gradually whisk in the seafood or chicken stock, ensuring there are no lumps as you add it. Continue whisking as you add the softened cream cheese and heavy cream. Add the dried basil at this point, allowing it to infuse its flavor as the sauce simmers. Bring the mixture to a gentle simmer and cook for several minutes, stirring occasionally, until the sauce begins to thicken slightly.

6-Step 6: Add Spinach and Seasonings Add the fresh baby spinach to the sauce, stirring until it wilts. This should only take 1-2 minutes. The spinach will shrink dramatically, so don’t worry if it seems like a lot at first. This step adds both nutrition and vibrant color to your dish. Mix in the crushed red pepper flakes and freshly grated Parmesan cheese, stirring until the cheese has melted and is fully incorporated. Taste the sauce at this point and adjust the seasonings as needed, adding more salt or red pepper flakes according to your preference.

7-Step 7: Combine Everything Add the cooked tortellini to the sauce, tossing gently to coat each piece. If the sauce seems too thick, add a splash of the reserved pasta water to reach the desired consistency. The sauce should generously coat the pasta without being overwhelming. Finally, add the cooked shrimp back to the pan, gently folding them in to combine. You just want to warm the shrimp through, not cook them further. Serve immediately while everything is hot and the sauce is at its creamiest.
