Spring Shrimp Lettuce Tacos with Peanut Sauce
/We're piling tender shrimp, crunchy matchstick veggies, and quick-marinated ginger-garlic shiitakes inside soft, velvety butter lettuce cups. The real game-changer here is the glossy peanut sauce, which gets a subtle hit of dashi powder for a deep, unexpected layer of umami. It's bright, fresh, beautifully low-carb, and comes together in about 35 minutes flat.
INGREDIENTS HIGHLIGHTS
MARINATED MUSHROOMS
Shiitake Mushrooms (4–5 oz, caps sliced) — Earthy, meaty, and sponge-like; the perfect vehicle to absorb the rich marinade and add a hearty texture to the tacos.
Minced Ginger & Garlic (1 teaspoon each) — Sharp, pungent aromatics that infuse the mushrooms with a vibrant, warming punch of flavor.
Soy Sauce & Rice Vinegar — A classic savory-tart balance that provides a deep, umami base and cuts through the richness of the mushrooms.
Roasted Sesame Oil (1 teaspoon) — Deeply toasted and fragrant oil that wraps the mushrooms in a warm, nutty aroma.
PEANUT SAUCE
Smooth Peanut Butter (¼ cup) — Rich, velvety anchor of the sauce that provides a creamy mouthfeel and a classic nutty backdrop.
Hoisin Sauce (2 tablespoons) — Thick, sweet, and savory glaze that introduces a complex, spiced depth to the peanut base.
Soy Sauce & Rice Vinegar (1 tablespoon each) — Salty and acidic elements that sharpen the sauce, balancing the sweetness of the hoisin.
Dashi Powder (¼ teaspoon) — The secret ingredient; a subtle, deeply savory hint of the sea that adds an unexpected layer of umami.
LETTUCE SHELL & FILLINGS
Butter Lettuce (1 head) — Crisp, tender, and perfectly cupped leaves that act as a clean, refreshing vehicle for the fillings.
Shrimp (½ lb, cooked and peeled) — Sweet, tender seafood centerpiece that pairs beautifully with the rich, bold sauce.
Carrot & English Cucumber (Matchsticks) — Cool, refreshing matchsticks that give the tacos an essential, vibrant crunch to counter the soft fillings.
Fresh Coriander (¼ cup, chopped) — Citrusy, bright herb that cuts through the savory elements and lifts the entire dish.
Roasted Sesame Seeds (1 tablespoon) — Tiny, nutty gems sprinkled on top to offer a final, delicate crunch.
Marinating the Mushrooms
Whisk the marinade ingredients in a bowl, toss the shiitakes until fully coated, then transfer everything to a plastic bag to chill and steep in the fridge for at least 2 hours.
Making the Peanut Sauce
Whisk the smooth peanut butter, hoisin, and aromatics in a single bowl, then stir in a splash of warm water until it reaches a perfectly glossy, drizzlable consistency.
Assembling the Tacos
Build your tacos inside the soft butter lettuce cups—layering the crunchy matchstick veggies first, topping them with the marinated mushrooms and sweet shrimp, and finishing with a drizzle of peanut sauce and a shower of sesame seeds.
