Serves 4 · about 50 minutes · one sheet pan, one blender, one skillet
If you like butter chicken, you will love this butter pumpkin shrimp. It is sweet and creamy with warming spices and a bit of heat from the Fresno. Cilantro lime basmati and toasted coconut keep it feeling bright, fragrant and deeply satisfying.
Two things carry it. The sauce gets its body from roasted squash in a blender rather than an hour of reducing, and the shrimp go in at the very end — three or four minutes, judged by how far they curl rather than by the clock.
At a glance
About 50 minutes
The pumpkin roasts and the rice cooks while you do everything else, so the hands-on time is closer to twenty minutes. The shrimp are the last four.
Serves 4
One 16 oz bag of shrimp, four 4 oz servings, over cilantro lime basmati. It halves cleanly if you are cooking for two and want leftovers of the sauce.
Blended, not reduced
Roasted kabocha and a can of coconut milk through a blender. That is where the body comes from — no long simmer, no cream.
Watch for the C
Shrimp are done when they curl into a loose C. A closed O means overcooked, and a thick sauce keeps cooking them after the heat is off.
Read the shape, not the clock
A shrimp tells you when it is done by how tightly it curls.
Three or four minutes is the guide, but shrimp go from perfect to rubbery in well under a minute, and a pan of hot sauce keeps cooking them after the heat is off. The reliable signal is geometry: as it cooks a shrimp draws itself into a C, and if it keeps going it closes into an O. C is dinner. O is a mistake you cannot undo.
Straight and translucent Not yet
Raw. Grey-blue and floppy, lying flat in the sauce. It will start to firm and turn opaque from the outside in within about a minute.
A loose C — opaque, still plump Pull it here
The shrimp has curled but the head and tail ends are still well apart. Opaque all the way through, pink outside. Take the pan off the heat now; carryover in the sauce finishes the job.
A tight C, edges firming Last chance
The gap has closed to about a fingertip. Still good if you serve immediately, but there is no margin left. If it is heading to the table in a few minutes, you have already gone slightly far.
A closed O Overcooked
Head touching tail. The flesh has squeezed out its moisture and gone springy and dense. Nothing recovers it — this is the texture people mean when they say they do not like shrimp.
Ratings are how far along the shrimp is, not how good. Because this sauce is thick and holds heat, pull the pan a shade earlier than you would from a dry skillet — the shrimp continue to tighten while you are spooning it out.
Butter Pumpkin Shrimp with Toasted Coconut, Lime and Fresno
Chef Miriam Thom
50 minutes
If you like butter chicken, you will love this butter pumpkin shrimp. It's sweet and creamy with warming spices and a bit of heat from the Fresno. Cilantro lime basmati and toasted coconut keep it feeling bright, fragrant and deeply satisfying.
Serves 4 — one 16 oz bag of shrimp, four 4 oz servings. About 50 minutes.
Ingredients
16 oz Mangrove Black Tiger Shrimp (one bag), peeled and deveined, thawed overnight in the fridge and patted dry
2 cups cubed kabocha or sugar pumpkin (about half a small kabocha)
½ red bell pepper, thinly sliced
1 can (13.5 oz) full-fat coconut milk
1⅓ cups basmati rice, rinsed
3 tbsp butter, divided — 1 tbsp for the sauce, 2 tbsp for the skillet
1 tbsp extra-virgin olive oil
3 garlic cloves, grated
1 tbsp fresh ginger, grated
1½ tsp garam masala
4 green cardamom pods, lightly crushed
1 Fresno chile, thinly sliced
3 limes
1 tbsp apple cider vinegar
1 tsp fish sauce
½ cup fresh cilantro leaves, roughly chopped, plus a little for garnish
¼ cup unsweetened coconut flakes
¼ cup pepitas
Salt
Directions
Heat the oven to 425°F. Toss the pumpkin with the olive oil and a pinch of salt and roast for 20–25 minutes, until caramelised and tender.
Meanwhile, cook the basmati according to package directions. Fluff it, then fold through most of the cilantro, the zest and juice of 1 lime and salt to taste. Cover and keep warm.
Toast the coconut flakes and pepitas in a dry skillet over medium heat, shaking often, until the coconut is golden and the seeds start to pop, 3–4 minutes. Tip them out and set aside — they catch fast, so don't walk away.
Reserve about ½ cup of the roasted pumpkin. Let the rest cool for a few minutes, then blend with the coconut milk, 1 tbsp butter, half the ginger, half the garlic, ½ tsp lime zest and a pinch of salt until smooth. Hot liquid builds steam in a blender — leave the lid vented and start on low.
Melt the remaining 2 tbsp butter in a large skillet over medium heat. Add the garam masala, crushed cardamom pods and the remaining garlic and ginger, and cook, stirring, for about 45 seconds, until fragrant. This is where the warming spice comes from — don't skip it. Add the red pepper and half the Fresno and cook 2–3 minutes, until softened.
Pour in the pumpkin-coconut sauce and simmer gently for 3–4 minutes. Stir in the vinegar and fish sauce, then taste and adjust with lime juice and salt. Fish out the cardamom pods.
Slip in the shrimp and simmer gently, stirring once or twice, for 3–4 minutes — just until they turn opaque and curl into a loose C. They keep cooking in the hot sauce, so pull them a shade early rather than late.
Spoon into a shallow serving dish and scatter with the reserved roasted pumpkin, the remaining Fresno, the last of the cilantro and the toasted pepitas.
Serve over the cilantro lime basmati with the toasted coconut. Cut the last lime into wedges for the table, and finish each plate with a generous squeeze.
Optional: if you can get cilantro flowers, scatter them over at the end — they're delicate and peppery and make the dish look like it came out of a restaurant.

How the sauce actually gets built
The sauce is blended, not reduced — and the spices are bloomed apart from it.
Butter chicken gets its body from long simmering. This gets it from roasted squash put through a blender, which is why it takes fifty minutes instead of two hours. That means three separate moves, and doing them in the wrong order is the only way to get a flat, raw-tasting sauce.
1
Roast the pumpkin, don't boil it
425°F until the edges caramelise. That browning is where the sweetness comes from, and you cannot get it back later — simmered squash makes a sauce that tastes thin and vegetal no matter what you add to it.
2
Vent the blender lid
Let the pumpkin cool a few minutes, then blend with the coconut milk on low before you go up. Hot liquid turns to steam in a sealed jug and pushes the lid off — keep it vented and hold a towel over the top.
3
Bloom the spices separately
Garam masala, crushed cardamom, garlic and ginger in butter for about 45 seconds, until they smell fragrant rather than dusty. Fat carries those flavours in a way liquid does not. Then pour the sauce in.
Swaps that work
The method holds whatever you put through it — roast something sweet, blend it with something rich, bloom a warm spice in fat, and add the protein last.
| As written | Closest swap | If you are improvising | |
|---|---|---|---|
| The shrimp | 16 oz Mangrove Black Tiger Shrimp | Any raw peeled shrimp, same timing | Scallops — two minutes, turned once; or firm white fish in 1-inch pieces |
| The squash | 2 cups kabocha or sugar pumpkin | Butternut, which is sweeter and smoother | Sweet potato — denser, so thin the sauce with a splash more coconut milk |
| The richness | 1 can full-fat coconut milk | Coconut cream, thinned with water | Cashew cream, for something closer to a classic butter sauce |
| The spice | 1½ tsp garam masala + cardamom pods | Curry powder, with the cardamom kept | Cumin, coriander and a cinnamon stick, bloomed the same way |
| The heat | 1 Fresno chile, sliced | Red jalapeño, or half a serrano | A pinch of Aleppo stirred in at the end, for warmth without the bite |
| The grain | Cilantro lime basmati | Jasmine rice, same treatment | Warm naan or roti, and skip the rice entirely |
| The crunch | Toasted coconut flakes and pepitas | Toasted cashews or almonds | Fried shallots, which add salt as well as texture |
The sauce is the make-ahead
Everything up to the shrimp keeps. Roast the pumpkin, blend the sauce and bloom the spices, then refrigerate the finished sauce for up to three days — it thickens as it sits, so loosen it with a splash of water or coconut milk when you reheat. The toasted coconut and pepitas keep for a fortnight in a jar at room temperature.
Cook the shrimp fresh. They take four minutes, they are the one thing that cannot be reheated without going rubbery, and they are the reason to make this rather than a vegetable curry.
Why these shrimp hold up in a sauce this rich
Black tiger shrimp are firmer and meatier than the small warm-water shrimp most curries are built on, which matters when the sauce is this thick — they stay distinct instead of disappearing into it. They also hold their snap through the four minutes of gentle simmering the recipe asks for, where a softer shrimp would go woolly.

Questions about this one
How do I know when the shrimp are done?
By shape. A raw shrimp lies straight; a cooked one curls into a loose C; an overcooked one closes into a tight O. Pull the pan off the heat at the loose C — opaque through, still plump, with a clear gap between head and tail. The sauce is thick and holds heat, so they keep tightening after the burner is off.
Can I just stir the spices into the sauce?
You can, and it will taste noticeably flatter. Ground spices are fat-soluble — giving them 45 seconds in melted butter opens them up in a way stirring them into liquid does not. It is the single cheapest step in the recipe and the one that makes it taste like it took longer than it did.
Is blending the hot pumpkin safe?
With one precaution. Hot food turns to steam in a sealed blender jug and can force the lid off. Let the pumpkin cool for a few minutes first, fill the jug no more than two-thirds, remove the centre cap so steam escapes, hold a folded towel over the opening and start on the lowest speed before working up.
What if I can't find kabocha?
Butternut is the easiest swap and slightly sweeter; sugar pumpkin works too. Whatever you use, roast rather than boil it — the caramelised edges are where the sauce gets its depth, and boiled squash gives you a thin, vegetal sauce no amount of spice will rescue.
How hot is this, and can I dial it down?
Mild to medium as written. One Fresno split between the sauce and the garnish gives warmth rather than burn. For less, seed the chile or use only the half that goes in early — the raw slices scattered at the end are the sharper hit. For more, add a second, or a pinch of cayenne with the garam masala.
How should I thaw Seatopia seafood?
Overnight in the refrigerator in the sealed pack, about 12 hours, then pat the shrimp dry. In a hurry, submerge the sealed pack in a bowl of chilled water for 20 to 30 minutes, changing the water once. Never at room temperature, and never in warm water.
