A restaurant portion of Butter Prawns (6-8 medium-large shell-on prawns with egg floss) comes in at around 580 calories, with 28g protein, 14g carbs and 44g fat. The prawns themselves are not the problem; it's the butter, the deep-frying oil and those crispy egg-yolk strands that stack the numbers fast.

The real talk

Butter Prawns is one of those dishes where the main ingredient is genuinely good for you and then the cooking method absolutely wrecks the macro profile. You get prawns, which are lean and high-protein, but they go into a deep fryer first, then get tossed in a wok with a generous amount of butter, evaporated milk, curry leaves, and egg-yolk floss fried in more butter. The egg floss alone contributes around 115 calories. The butter base adds another 130 calories. So out of 580 total calories, roughly 390 come from fat sources. If you've never had this dish, picture crispy golden prawns coated in a fragrant, slightly creamy sauce with delicate egg strands that melt on your tongue. It's genuinely one of the better things Malaysian Chinese cuisine has produced. Worth eating. Just not every day, lah.

The version you order matters a lot. A home-cooked pan-fried version with the same butter and egg floss but without deep-frying sits around 280 calories, basically half the restaurant number, because you skip the absorbed frying oil. The salted egg version pushes up to 640 calories because salted egg yolks replace or supplement the egg floss and those yolks are very fat-dense. Portion size is another big variable. A restaurant order is typically shared between two or three people alongside rice and vegetables, so your actual intake might be 180-200 calories per person if you split it properly. The calorie estimates here are best guesses since standardised data for this dish is genuinely hard to find, so treat the numbers as a solid ballpark rather than exact figures.

What exactly is Butter Prawns and what makes it so rich?

Is Butter Prawns a good source of protein or should I avoid it when dieting?
The prawns themselves are solid protein at around 28g per portion, which is decent. The problem is the fat coming in at 44g, mostly from butter and frying oil.
