If you love shrimp with bold, bright flavour but minimal effort, this butterflied Bahian lemon shrimp is about to become your new favourite. Inspired by the coastal cooking of Bahia, Brazil — where coconut milk, citrus, and a whisper of chilli pepper meet fresh seafood — this dish comes together in just 35 minutes from start to plate.
The magic is in the marinade. Creamy unsweetened coconut milk mellows the sharp lemon juice, while garlic, paprika, and cayenne build layers of flavour without overwhelming the sweet, briny shrimp. A quick 30-minute soak is all you need — any longer and the acid begins to break down the delicate texture.
I originally made this as an appetizer, but it became a full dinner the moment I tossed it over garlic buttered noodles. It’s equally good over brown rice, quinoa, or even on top of a fresh salad the next day.
The best part? Five minutes of prep, one pan, and a dish that tastes like you spent all afternoon in the kitchen.
Butterflied Bahian Lemon Shrimp (Brazilian Coconut Marinade)
Ingredients
Cupcake Ingredients
- 1 ¼ sticks unsalted butter cubed
- ½ cup bittersweet chocolate chopped
- ½ cup unsweetened chocolate chopped
- 3 medium eggs
- ½ cup turbinado sugar
- 1 pinch salt
- ½ cup coconut rum
- 1 tsp vanilla extract
- ½ tsp cayenne pepper
- 1 tsp cinnamon
- 1 tsp instant espresso powder
Frosting Ingredients
- ⅓ cup semisweet chocolate chopped
- 2 tbsp unsalted butter
- 1 cup granulated sugar
- 3 medium egg whites
- 0.3 tsp cream of tartar
- 2 tsp vanilla extract
- ⅓ cup water
- 1 pinch fine sea salt
- as needed shaved chocolate for topping
Instructions
Cupcake Instructions
- Preheat the oven to 325°F / 160°C (165°C fan-forced).
- Line the cupcake pan with cupcake papers.
- Chop the bittersweet and unsweetened chocolate and place in a heatproof bowl set over a saucepan of gently simmering water (double boiler). Add the cayenne pepper and cinnamon. (Tip: flavoured bittersweet chocolate, such as chilli or orange-infused, works beautifully here.)
- Stir until the chocolate is melted.
- In another heatproof bowl, put the eggs, turbinado sugar and salt. Place the bowl on the same double boiler and whisk until the mixture is warm for about 2 to 4 minutes.
- Transfer the egg mixture to a stand mixer fitted with the whisk attachment (or use a hand mixer). Whip on medium speed until the mixture has tripled in volume, about 5 minutes. It should be pale, thick, and leave a ribbon trail when the whisk is lifted.
- While that is mixing, combine the coconut rum, vanilla, and instant espresso powder in a small saucepan and bring to a low boil.
- Decrease the speed of the mixer to low and gradually pour in the rum/coffee mixture in a thin, steady stream.
- Then add the melted chocolate mixture and mix on low speed until fully combined, about 2 minutes. Scrape down the sides of the bowl as needed.
- Gradually add the butter until all is incorporated.
- Scoop batter into the cupcake papers.
- Bake at 325°F / 160°C (165°C fan-forced) for about 10 minutes (for mini cupcakes) and 15 minutes (for regular cupcakes). The cupcakes are done when the tops are set and slightly firm to the touch — they will continue to firm up as they cool.
- Let cool completely.
Frosting Instructions
- Melt chocolate and butter in a microwave-safe bowl in 30-second intervals using a microwave-safe bowl until all melted. Set aside to cool slightly.
- Whisk the egg whites, sugar, cream of tartar, salt and 1/3 cup (80ml) of water in a heatproof bowl.
- Place bowl over a double boiler beat with a hand mixer on low, then gradually increase speed to form soft peaks. This takes about 5 minutes. The mixture should reach 160°F / 71°C to pasteurise the egg whites.
- Remove the bowl from the pan and continue beating until the mixture becomes cool and fluffy.
- Fold in vanilla, then the chocolate.
- Transfer the frosting to a piping bag fitted with a large round or star tip (or a zip-top bag with one corner snipped off).
- Pipe the frosting on top of each cupcake.
- Top with shaved chocolate.

What Makes This Butterflied Bahian Lemon Shrimp Special
Bahian cooking — from the Brazilian state of Bahia — is famous for its bold use of coconut milk, citrus, and chilli peppers, influenced by West African, Portuguese, and Indigenous traditions. This recipe captures that spirit in a weeknight-friendly format.
What sets this dish apart from typical garlic butter shrimp is the coconut milk marinade. Rather than drowning the shrimp in heavy cream or butter, the coconut milk creates a silky coating that caramelises beautifully in the hot pan. The lemon juice cuts through the richness, and the cayenne provides a gentle warmth that builds without burning.
Butterflying the shrimp is the other key detail. By splitting each shrimp open and pressing it flat, you double the surface area that contacts the marinade and the hot pan. The result is more flavour absorption and a better sear — golden edges with a tender, juicy centre.
Equipment You’ll Need
- Large sauté pan or 12-inch skillet — you need enough surface area to cook the shrimp in a single layer without crowding, which is essential for searing rather than steaming.
- Medium mixing bowl — for combining and marinating the shrimp in the coconut-lemon mixture.
- Sharp paring knife — precision matters when butterflying shrimp. A dull knife risks tearing the flesh or cutting all the way through.
- Tongs — the best tool for flipping individual shrimp quickly and maintaining the butterfly shape.
- Citrus juicer or reamer — a nice-to-have that makes extracting 3 tablespoons of fresh lemon juice faster and ensures no seeds end up in the marinade.
Tips for Best Results
- Do not over-marinate. Thirty minutes is the sweet spot. Lemon juice is acidic enough to start “cooking” the shrimp (like ceviche), and after 45-60 minutes the texture becomes mealy.
- Pat the shrimp dry before they hit the pan. Excess marinade creates steam instead of sear. Shake off the liquid and let the hot oil do its work.
- Don’t crowd the pan. Cook in two batches if needed. Overcrowding drops the pan temperature and the shrimp will steam and turn rubbery instead of developing golden edges.
- Use jumbo or colossal shrimp (U15 count). Smaller shrimp are harder to butterfly cleanly and overcook in seconds. The larger the shrimp, the more forgiving the cooking window.
- Get the pan properly hot. The oil should shimmer and nearly smoke before the first shrimp goes in. This is what gives you that restaurant-quality sear.
Substitutions and Variations
- Lime instead of lemon: Lime is actually more traditional in Bahian cooking and gives a slightly more tropical, rounded acidity.
- Light coconut milk: Cuts the fat content significantly with only a modest loss in richness. Good option if you’re watching calories.
- Smoked paprika instead of regular: Adds a deeper, more complex flavour that pairs beautifully with the coconut milk.
- Add fresh cilantro: A handful of chopped cilantro stirred in at the end or scattered over the top is very traditional for Bahian seafood dishes.
- Spice it up: Increase cayenne to ½ teaspoon or add a minced fresh chilli pepper (such as malagueta or Thai bird’s eye) for authentic Bahian heat levels.
- Dendê oil swap: For a more authentic Bahian flavour, replace the olive oil with 1 tablespoon of dendê (red palm oil), which is the traditional fat used in Bahian cuisine.
Storage and Reheating
- Refrigerator: Store cooked shrimp in an airtight container for up to 2 days. The texture is best within the first 24 hours.
- Freezer: Cooked shrimp freeze well for up to 1 month. Thaw overnight in the refrigerator — never at room temperature.
- Reheating: Warm gently in a skillet over medium-low heat with a splash of water or coconut milk to prevent drying out. Avoid the microwave, which makes shrimp rubbery and tough.
- Meal prep note: These shrimp are excellent cold on salads the next day, so reheating is optional.
What to Serve With This
- Garlic buttered noodles — the rich butter and garlic complement the coconut-lemon shrimp beautifully.
- Brazilian-style white rice — sautéed with garlic and cooked in chicken broth for extra flavour.
- Quinoa — a lighter, protein-rich base that lets the shrimp flavour shine.
- Mixed green salad with a lime vinaigrette — keeps the meal light and fresh.
- Farofa — toasted cassava flour, the classic Bahian side dish, adds crunch and an authentic Brazilian touch.
- Sautéed greens — collard greens or kale cooked with garlic mirrors the traditional Bahian pairing.
Frequently Asked Questions
What does butterflying shrimp mean?
Butterflying means cutting each shrimp along the outer curve about three-quarters of the way through, then pressing it open so it lies flat like a butterfly wing. This increases surface area for better marinade absorption and faster, more even cooking.
Can I use frozen shrimp for this recipe?
Yes, but thaw them completely first. Place the frozen shrimp in a colander and run cold water over them for 5-10 minutes until fully defrosted. Pat them very dry with paper towels before butterflying and marinating.
Why is the marinating time only 30 minutes?
The fresh lemon juice in the marinade is acidic enough to begin denaturing the shrimp protein — essentially starting to “cook” them chemically, similar to ceviche. Beyond 30-45 minutes, the texture becomes mushy and chalky rather than tender and snappy.
Can I grill these shrimp instead of sautéing?
Absolutely. Thread the butterflied shrimp onto skewers (soak wooden skewers for 30 minutes first) and grill over medium-high heat for 2-3 minutes per side. The coconut milk marinade caramelises beautifully over open flame.
What size shrimp should I buy?
Look for jumbo shrimp labelled U15 or 13/15 count (meaning 13-15 shrimp per pound). These are large enough to butterfly cleanly and have a meatier texture that holds up well to the marinade and high-heat sautéing.
Is this dish spicy?
With only ¼ teaspoon of cayenne pepper, the heat level is very mild — more of a warm tingle at the back of the throat than any real burn. If you prefer more heat, increase the cayenne to ½ teaspoon or add a sliced fresh chilli.
The Bahian Tradition Behind This Dish
Bahia, the northeastern Brazilian state with its capital in Salvador, is widely regarded as the culinary heart of Brazil. Its cuisine is a direct result of the African diaspora — enslaved West Africans brought ingredients, techniques, and flavour combinations that merged with Indigenous Brazilian and Portuguese cooking traditions. The use of coconut milk with seafood is one of the most iconic elements of Bahian food, appearing in dishes like moqueca (coconut fish stew) and vatapá (a thick shrimp paste). This butterflied shrimp recipe simplifies those traditional flavour profiles into a quick, accessible format while honouring the essential combination of coconut, citrus, and gentle chilli heat that makes Bahian cooking so distinctive.
