Creating this delicious Shrimp Tomato Spinach Pasta in Garlic Butter Sauce is straightforward if you follow these simple steps:

1. Cook the Pasta: Begin by boiling a large pot of salted water. Cook the spaghetti or linguine according to package instructions until al dente. Drain and set aside.

2. Prepare the Shrimp: In a large skillet, melt 2 tablespoons of butter over medium heat. Add the shrimp, seasoning with salt and pepper. Cook for about 2-3 minutes on each side, or until they turn pink and opaque. Remove shrimp from the skillet and set aside.

3. Sauté Garlic: In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add minced garlic and red pepper flakes (if using). Sauté for 1-2 minutes until fragrant, being careful not to burn the garlic.

4. Add Tomatoes: Toss in the halved cherry tomatoes. Cook for 3-4 minutes until they begin to soften and release their juices.

5. Incorporate Spinach: Add chopped spinach to the skillet and stir until it wilts down, about 2 minutes.

6. Combine Ingredients: Return the cooked shrimp to the skillet. Add the drained pasta and fresh lemon juice. Toss everything together gently to combine and heat through.

7. Adjust Seasoning: Taste the pasta and adjust seasoning with more salt and pepper if needed.

8. Serve: Plate the pasta and sprinkle with grated Parmesan cheese. Add fresh basil leaves for garnish, if desired.
