Demystifying Cornstarch: What Does It Really Do to Shrimp?

This is an easy-to-make recipe for Bang Bang Shrimp from Bonefish Grill. The shrimp is extra crispy and coated in a sauce that is sweet, spicy, and savory.

Made with just a few ingredients, this shrimp recipe is perfect as a main course or appetizer. For a tasty mix of Mexican and Asian food, we also love to put Bang Bang Shrimp in corn tortillas with fresh cilantro.

As someone who loves frying up crispy golden shrimp at home I’ve always been told that the secret is cornstarch. Just coat the shrimp in cornstarch and cornstarch only – no flour or batter. This will make your fried shrimp extra crispy and light, I was assured. But what does cornstarch actually do to the texture and flavor of shrimp when you fry it? I decided to dig into the science and find out.

A Light, Crispy Coating

The number one benefit of using cornstarch for frying shrimp is achieving an ultra light super crispy crust. Cornstarch creates a thin delicate coating that gets very crisp once hit with hot oil. It seems to crisp up even better than flour or beer batters. The cornstarch dries out quickly in the oil, setting and hardening around the shrimp to form a shell-like cage of crunch.

Flour coatings can turn gummy or bready when fried. Thick beer batters opaque the shrimp flavor. But cornstarch provides a transparent sheath of texture that keeps the shrimp’s sweet taste and succulence center stage. It’s like wrapping the shrimp in lace – you still see and taste the shrimp itself through the lacy crust.

Sealing in Moisture

Another perk of cornstarch is that it seals in moisture and flavor exceptionally well as it fries. While letting moisture escape is crucial for achieving that desired crispy texture, you still want the shrimp inside to be plump, tender and juicy.

A cornstarch coating seems to lock in just enough moisture inside the shrimp to keep it mouthwateringly juciy, while still crisping up the exterior. The thin, brittle structure of the cornstarch lets steam vent during cooking. But it also conveniently forms a protective, non-porous barrier against moisture loss.

Tenderizing Effect

Interestingly, cornstarch appears to have an almost tenderizing effect on shrimp as it cooks. The shrimp emerges from the fryer incredibly succulent and soft – moreso than you’d expect. It makes the shrimp almost melt-in-your-mouth tender.

This is likely because cornstarch gelatinizes when heated in liquid. Some of that gelatinization seems to permeate the flesh of the shrimp, making it more soft and luscious. The cornstarch may also help break down tough proteins and connective tissue in the shrimp through its gelatinization.

Downside – Slow Browning

The only potential downside of using cornstarch for frying shrimp is that it can take a little longer for the coating to turn that beautiful golden brown color. The tiny cornstarch granules don’t contain the proteins and sugars that accelerate browning in flours and batters.

So you have to be patient and let the shrimp fry for a few minutes longer. But once that golden crust finally forms, it will be thinner,crisper, and less bready or gummy than other coatings. Just keep an eye on it so you don’t overcook the interior while waiting for the color change.

Extra Crispy Bang Bang Shrimp

To get the best crispy and juicy cornstarch-fried shrimp, I suggest following a recipe like Bang Bang Shrimp. It uses a mixture of cornstarch and egg whites to adhere the cornstarch to the shrimp and seal in flavor. Frying time is a little over 3 minutes – long enough achieve ideal texture.

The sauce pairing is also crucial. The sweet chili sauce, spicy sriracha, and tangy mayo completely complement the crispy fried shrimp. Together they provide sweet, savory, spicy and creamy flavors that balance the crispy crust.

Takeaway – Stick with Cornstarch!

After running these experiments, I’m fully convinced that cornstarch is the best way to achieve premium texture and flavor when frying shrimp at home. The delicate, crispy crust and juicy interior can’t be beat. While it may brown slightly slower than other coatings, the results are well worth the extra minute or two.

For my shrimp frying needs, I’m sticking with cornstarch from here on out. No tedious beer battering or risk of gummy flour coats. Just quick and easy crispy, juicy fried shrimp everyone will devour. Pass the sweet chili sauce for dunking!

So next time you’re frying up some shrimp, step away from the flour and reach for the cornstarch instead. Your tastebuds will thank you. The only hard part is waiting for that gorgeous golden color to emerge so you can dig in!

  • Ultra crispy, delicate coating
  • Seals in moisture and flavor
  • Tenderizes the shrimp texture

It may take a little longer to brown, but the results are worth it! Use cornstarch for your crispiest, juiciest fried shrimp ever.

I have been making Honey Walnut Shrimp for years now. When I first made that recipe, I realized that cornstarch was the ingredient that would cling to the shrimp easily and it would crisp up nicely.

It helps make a batter that coats the shrimp, kind of like a beer batter, when you add it to egg white. It’s so crispy and tasty when it’s done cooking that you won’t want to use flour again! Cornstarch batter takes a little longer to brown, but it’s well worth the wait.
