Cook the linguine in salted boiling water until al dente, saving 1/2 cup of the pasta water before draining.
Meanwhile, heat the olive oil and 2 tbsp butter in a large skillet over medium heat. Add the sliced garlic and pepper flakes and cook 1 minute.
Raise the heat to medium-high, add the shrimp in one layer, season with salt and pepper, and cook 1-2 minutes per side until pink. Move the shrimp to a plate.
Pour in the broth and the juice of the lemon, scraping the pan, and simmer 2 minutes. Stir in the remaining 2 tbsp butter.
Add the linguine and shrimp, toss with splashes of pasta water until the sauce coats the noodles, and finish with chopped parsley and Parmesan.
