Boil a large pot of salted water and cook the pasta until just al dente, then drain and set aside.
Heat olive oil in a large frying pan over medium heat; add the peeled shrimp and cook for 2-3 minutes per side until they turn pink and are opaque. Remove shrimp from the pan and set aside.
Add the minced garlic and butter to the same pan; sauté for about 30 seconds until fragrant and the butter has melted, creating a fragrant garlic butter base.
Return the cooked shrimp to the pan, tossing gently to coat them in the garlicky butter mixture; cook together for another 1-2 minutes to meld the flavors.
Stir in the drained pasta, tossing well to coat the noodles evenly with the garlic butter and shrimp juices, creating a glossy, flavorful sauce.
In a small skillet, toast the breadcrumbs over medium heat until golden brown and crispy, about 2-3 minutes, then sprinkle over the pasta for added crunch and flavor.
Season everything with salt and freshly ground pepper to taste, then garnish with chopped cilantro or parsley if desired.
Serve the garlic butter shrimp pasta hot, with optional extra herbs or breadcrumbs on top for garnish, and enjoy the comforting blend of flavors and textures.
