Cook the linguine or spaghetti according to package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter and olive oil over medium heat. Add the minced garlic and red pepper flakes, cooking for about 1 minute until fragrant.
Add the shrimp to the skillet, seasoning with salt and pepper. Cook for 2-3 minutes until the shrimp turn pink.
Pour in the white wine (or chicken broth) and lemon juice, bringing the mixture to a simmer. Cook for an additional 2-3 minutes until the sauce slightly thickens.
Stir in the cooked pasta and chopped parsley, tossing to combine. Remove from heat and sprinkle with Parmesan cheese.
For the garlic bread, preheat the oven to 375°F. Mix the softened butter, minced garlic, and chopped parsley in a small bowl. Spread the mixture evenly over the sliced French bread.
Place the bread on a baking sheet and bake for 10-12 minutes until golden and toasted.
Serve the shrimp scampi over pasta in bowls with garlic bread on the side.
