- In a large pot, cook the linguine according to the instructions on the package. Once done, drain the pasta and set it aside. 
- In the same pot, heat the olive oil along with 2 tablespoons of butter over medium heat. Once melted, add the minced garlic and red pepper flakes, cooking until the garlic becomes fragrant. 
- Season the shrimp with salt and pepper to taste, then add them to the pot. Sauté the shrimp until they turn a light pink, ensuring they are cooked through. Add the Italian seasoning and baby spinach, and cook until the spinach wilts. 
- Return the cooked pasta to the pot and add the remaining butter, Parmesan cheese, and chopped parsley. Stir thoroughly until the butter has melted and the ingredients are well incorporated. 
- Pour in the lemon juice and toss to coat everything evenly. Serve immediately and enjoy the dish’s rich flavors.
