Garlic Butter Shrimp Pasta (Bright, Buttery, 20 Minutes)

Garlic butter shrimp pasta is the dinner to make when you want something that tastes like a restaurant plate but cooks like a weeknight shortcut. There is no cream sauce to babysit and no long simmer: shrimp sear in garlic butter in minutes, lemon and parsley brighten the pan, and hot spaghetti plus a splash of pasta water turns it all into a glossy coating. It is light, buttery, and fast, and it stays firmly on the garlic-butter side of shrimp pasta — no heavy cream, which is what keeps it distinct from the creamy shrimp dishes around it.

Why This Recipe Works

• Shrimp cook in minutes: They go from translucent to pink in about 2 minutes per side, so the whole dish stays quick and the shrimp stay tender.
• Pasta water makes the sauce: Starchy cooking water emulsifies with the garlic butter into a light, glossy coating without any cream.
• Lemon keeps it bright: Juice and zest at the end cut the richness of the butter so the dish tastes fresh, not greasy.
• Garlic goes in last-ish: Adding garlic after the shrimp start cooking keeps it fragrant instead of burnt and bitter.

Ingredients

• 12 oz (340 g) spaghetti
• 1 lb (450 g) large shrimp, peeled and deveined, tails on or off
• 4 tablespoons (55 g) unsalted butter, divided
• 1 tablespoon (15 ml) olive oil

How to Make Garlic Butter Shrimp Pasta

Step 1: Cook the spaghetti

Boil the spaghetti in salted water until just shy of al dente. Reserve 1 cup (240 ml) of the cooking water, then drain.

Step 2: Sear the shrimp

Meanwhile, melt 2 tablespoons (28 g) of the butter with the olive oil in a large skillet over medium-high heat. Season the shrimp with salt and pepper, add in a single layer, and cook for 1 to 2 minutes per side until pink and just opaque. Remove to a plate.

Step 3: Build the garlic butter sauce

Reduce the heat to medium, melt the remaining 2 tablespoons (28 g) butter, and cook the garlic and red pepper flakes for 30 to 60 seconds until fragrant but not browned. Add 1/2 cup (120 ml) of the reserved pasta water and the lemon juice, scraping up the browned bits.

Step 4: Toss and serve

Add the drained spaghetti and toss for 1 to 2 minutes until glossy, loosening with more pasta water as needed. Return the shrimp, add the lemon zest and parsley, toss once more, and serve immediately with Parmesan if using.

Tips

• Pat the shrimp dry: Dry shrimp sear instead of steaming, which gives better color and flavor in the short cooking time.
• Do not overcook the shrimp: Pull them while they are just opaque; they finish warming in the hot pasta and turn rubbery if cooked twice over.
• Keep the garlic pale: Garlic that browns turns bitter fast, so keep the heat at medium and have the pasta water ready to pour in.
• Serve right away: Butter sauces tighten as they cool, so plate immediately and pass extra lemon at the table.

Storage

Refrigerate leftovers in an airtight container for up to 2 days. Reheat very gently in a skillet with a splash of water and a knob of butter, tossing just until warmed; avoid the microwave, which overcooks the shrimp quickly. Do not freeze.

Frequently Asked Questions

Is this the same as shrimp scampi?

It is very close: shrimp scampi is traditionally shrimp in garlic, butter, white wine, and lemon over pasta. This version skips the wine and leans on pasta water and lemon for the sauce, so it is a simpler, wine-free cousin.

Can I use frozen shrimp?

Yes. Thaw fully in the fridge or under cold running water, then pat very dry before searing so they brown properly.

What pasta shape works?

Spaghetti and linguine are classic because the light butter sauce coats long strands evenly. Angel hair also works if you shorten the cooking time; avoid very heavy tubes that the light sauce slides off.

How do I know the shrimp are done?

They curl into a loose C shape and turn pink and opaque. A tight O shape means they are overcooked, so pull them at the C stage.
