Miso Garlic Butter Shrimp Scampi

Miso garlic butter shrimp scampi is what happens when a classic Italian-American pasta night meets Japanese umami. White miso paste stirred into the garlic butter sauce adds a deep, savory backbone that makes the whole dish taste like it simmered for hours — but it comes together in 20 minutes. The shrimp sear in the same skillet, the pasta finishes in the sauce, and you have a weeknight dinner that feels like a date night.

Why You’ll Love This Miso Garlic Butter Shrimp Scampi

• Ready in 20 minutes — one skillet, one pot, done.
• White miso adds umami depth that regular scampi sauce lacks entirely.
• Uses just 1 lb of shrimp to serve 4 people — the pasta stretches the protein.
• The miso butter sauce clings to every strand of pasta instead of pooling at the bottom.
• Naturally dairy-free if you use olive oil instead of butter (though butter is better here).

Ingredients

• 1 lb 1 lb large shrimp (21-25 count), peeled and deveined (Leave the tails on if you want presentation points.)
• 12 oz 12 oz spaghetti or linguine (Linguine is traditional; spaghetti works fine.)
• 4 tbsp 4 tbsp unsalted butter (Divided: 2 for the shrimp, 2 for the sauce.)
• 2 tbsp 2 tbsp white miso paste (Shiro miso — the mildest, sweetest variety. Find it in the refrigerated Asian section.)
• 6 cloves 6 cloves garlic, thinly sliced (Sliced, not minced — slices soften and sweeten without burning as easily.)
• ½ cup ½ cup dry white wine (Sauvignon Blanc or Pinot Grigio. Cooking wine works but isn't as good.)
• ½ cup ½ cup pasta cooking water, reserved (This is the secret to a silky sauce. Do not drain all the water.)
• 1 1 lemon — zest and juice (The acid brightens the rich butter-miso sauce.)
• ¼ tsp ¼ tsp red pepper flakes (Optional. A little warmth against the richness.)
• ¼ cup ¼ cup fresh parsley, chopped
• Salt and pepper to taste (Go easy on the salt — miso is salty.)

Equipment

• 12-inch skillet (stainless steel or cast iron)
• Large pot for pasta
• Tongs
• Ladle for pasta water
• Microplane for lemon zest

How to Make Miso Garlic Butter Shrimp Scampi

Step 1 — Boil the pasta (10 minutes)

Bring a large pot of heavily salted water to a rolling boil. Cook the spaghetti 1 minute short of the package’s al dente direction — it will finish cooking in the sauce. Before draining, scoop out 1 full cup of pasta water and set aside. Drain the pasta.

Step 2 — Sear the shrimp (4 minutes)

While the pasta cooks, pat the shrimp dry and season with salt and pepper. Melt 2 tablespoons of butter in a 12-inch skillet over high heat until foaming. Add the shrimp in a single layer — do not crowd; work in two batches if needed. Sear without moving for 2 minutes until golden on the bottom. Flip and sear 1 more minute. The shrimp should be just barely cooked through (they’ll finish in the sauce). Transfer to a plate.

Step 3 — Build the miso garlic butter sauce (4 minutes)

Reduce heat to medium. Add the remaining 2 tablespoons of butter to the same skillet. Once melted, add the sliced garlic and red pepper flakes. Cook, stirring, for 60 seconds — the garlic should turn fragrant and just barely golden at the edges, not brown. Pour in the white wine and use a wooden spoon to scrape up any browned bits from the shrimp. Let the wine reduce by half, about 2 minutes. Remove the skillet from heat and whisk in the miso paste until dissolved. The off-heat moment prevents the miso from getting grainy.

Step 4 — Finish the pasta in the sauce (3 minutes)

Return the skillet to medium heat. Add the drained pasta and toss with tongs. Add ¼ cup of the reserved pasta water and toss vigorously — the starch in the water emulsifies with the butter and miso into a creamy, glossy sauce that coats every strand. Add more pasta water a tablespoon at a time if the sauce feels tight. Add the lemon zest, lemon juice, and half the parsley. Toss again.

Step 5 — Combine and serve (1 minute)

Return the shrimp to the skillet and toss gently to warm through — about 30 seconds. Do not overcook; the residual heat is enough. Taste and adjust seasoning — you likely won’t need salt because of the miso. Serve immediately in warm bowls, topped with the remaining parsley and an extra grind of black pepper.

Pro Tips

Reserve pasta water: This is the single most important step in any pasta dish. The starchy water is what turns butter and miso into a creamy sauce instead of an oily puddle.

Don’t burn the garlic: Sliced garlic burns faster than minced. Keep it moving in the pan and pull it off heat if it’s browning past golden. Burnt garlic is bitter and there’s no fixing it.

Miso off heat: Whisk the miso in after removing the pan from heat. High heat makes miso grainy and can kill its nuanced flavor.

Shrimp timing: Slightly undersear the shrimp. They’ll finish cooking when you toss them back into the warm sauce. Overcooked shrimp are rubbery.

Variations & Substitutions

Scallop version: Replace shrimp with sea scallops. Sear 2 minutes per side in a very hot, dry pan. The miso butter is even better with scallops.

Vegetarian: Skip the shrimp and add 1 lb of roasted broccoli florets and a can of drained chickpeas. Same sauce, same pasta.

Spicy miso: Use red miso instead of white for a deeper, saltier flavor, or add 1 tsp gochujang to the sauce.

Creamy version: Stir in ¼ cup heavy cream with the miso for an even richer sauce.

Storage & Reheating

Refrigerator: Leftovers keep 2 days in an airtight container. The pasta absorbs the sauce overnight, so it’s drier the next day.

Freezer: Not recommended — the shrimp texture suffers after freezing.

Reheating: Reheat in a skillet with 2-3 tablespoons of water or broth over medium heat, tossing until the sauce loosens and the shrimp is warmed through. Microwave works but can overcook the shrimp.

What to Serve With Miso Garlic Butter Shrimp Scampi

Frequently Asked Questions

What if I can't find white miso?

You can substitute 1 tablespoon of soy sauce plus 1 tablespoon of tahini — it won’t be identical but gives you the salty-creamy-umami profile. Or use yellow miso, which is slightly stronger; reduce to 1½ tablespoons.

Can I use frozen shrimp?

Yes. Thaw them in a bowl of cold water for 15 minutes, then pat very dry before searing. Wet shrimp steam instead of sear.

Is the wine necessary?

The wine adds acidity and depth. You can substitute ½ cup of chicken broth plus 1 tablespoon of lemon juice, but the flavor will be slightly less complex.

Can I make this gluten-free?

Use gluten-free spaghetti and substitute tamari for the miso (check the miso label — most are gluten-free, but some contain barley). Everything else is naturally gluten-free.
