My husband begs for this fresh seafood noodle dish every spring. Just 3 ingredients for absolute perfection

This slow cooker 3-ingredient garlic butter shrimp pasta is my springtime shortcut to a fresh seafood noodle dish that tastes far more luxurious than the effort it requires. It’s the kind of meal my husband actually requests as soon as the weather warms up—tender pink shrimp, long ribbons of pasta, and a glossy garlic butter sauce that clings to every strand. While slow cookers are more often associated with stews and roasts, here we use gentle, low heat to poach the shrimp and hydrate the pasta right in the same pot, giving you a deeply flavored, silky sauce with almost no hands-on work. With just three ingredients and a slow cooker doing the heavy lifting, it’s a practical way to bring a bit of coastal restaurant charm into a busy weeknight kitchen.

Serve this garlic butter shrimp pasta straight from the slow cooker into warm shallow bowls, topped with a sprinkle of chopped fresh parsley or chives if you have them on hand. A simple green salad with a lemony vinaigrette or a plate of steamed asparagus balances the richness of the butter and seafood. Crusty bread is lovely for catching every last bit of the glossy sauce. For drinks, a crisp white wine such as Pinot Grigio or Sauvignon Blanc, or even a dry sparkling wine, pairs beautifully with the garlicky butter and sweet shrimp.

Servings: 4

1 pound (450 g) large raw shrimp, peeled and deveined (tails on or off)

Prepare the slow cooker: Set a 4- to 6-quart slow cooker on LOW. There’s no need to preheat for long, but turning it on while you gather ingredients helps the butter start melting as soon as it goes in.

Layer the pasta: Break the long pasta in half so it fits more easily into the slow cooker. Scatter the dry pasta in an even layer across the bottom of the insert, fanning the strands out slightly so they’re not tightly clumped. This helps them cook more evenly in the melted garlic butter.

Add the garlic butter: Distribute the chunks of garlic herb butter evenly over the dry pasta. As the cooker warms, the butter will melt down, coating the noodles and forming the base of the sauce. Cover the slow cooker with the lid.

Start the cooking: Cook the pasta and butter mixture on LOW for 45 minutes to 1 hour, lifting the lid once or twice to gently toss the pasta with tongs so it gets evenly coated as the butter melts. The pasta will begin to soften but will not be fully tender yet. If any strands stick, simply separate them with the tongs as you turn them.

Add the shrimp: Once the pasta has softened and is mostly flexible, add the raw shrimp on top. Use tongs to gently nestle the shrimp down into the buttery pasta so they’re in contact with the hot sauce and not just sitting on the surface.

Finish cooking: Cover again and continue cooking on LOW for 20 to 30 minutes, checking once after 15 minutes. The shrimp are done when they are opaque, firm, and pink all the way through, and the pasta is just tender with a little bite. Give everything a final toss so the shrimp and noodles are thoroughly coated in the glossy garlic butter sauce.

Adjust texture and serve: If the pasta looks too tight or sticky, you can loosen the sauce by adding a splash of hot water from the kettle, then tossing again until the sauce looks silky and coats the noodles. Taste and, if desired, finish with a handful of chopped fresh herbs over the top for color. Serve immediately, straight from the slow cooker while steaming hot.

Because this dish is built on just three ingredients, each one matters. Choose good-quality shrimp (fresh or frozen, thawed and well-drained) and a garlic herb butter you truly like. If you only have plain butter, you can quickly turn it into garlic butter before starting: soften 1 cup butter and mash it with 3 to 4 finely minced garlic cloves and a pinch of salt and dried herbs like parsley or Italian seasoning. For a slightly lighter feel, you can use 3/4 cup garlic butter instead of a full cup and add a small splash of hot water to help the sauce coat the noodles. Different pasta shapes also work; fettuccine and linguine give you that classic ribbon look, but spaghetti or even tagliatelle behave similarly—just avoid very thick or very short shapes, which won’t match the long, glossy ribbons in the final dish. If you’d like more color without adding extra ingredients to the slow cooker itself, serve the pasta over a bed of baby spinach or arugula, letting the warm noodles wilt the greens. For a make-ahead variation, you can partially cook the pasta on the stovetop until just shy of al dente, then finish with the butter and shrimp in the slow cooker for a shorter cook time and slightly firmer texture. Finally, remember that slow cookers vary: the first time you make this, check on the pasta and shrimp a bit early so you can learn how quickly your particular model brings everything to that sweet spot of tender noodles and juicy, just-cooked shrimp.
