Ca Kho To (Vietnamese Caramelized Braised Fish) — Ad-Free Recipe, Ingredients First

The dish lives or dies on the nuoc mau: sugar cooked past golden to a bitter mahogany, just to the edge of burnt. Pull it too early and the braise is cloying; take it dark and it turns savory and smoky.

The Ingredients — and where to get them

Cook for 4 servings

Catfish or basa steaks

Cut crosswise into thick steaks, bone in — they hold together through the braise.

1.5 lb

Local / market

Sugar

For the nuoc mau caramel; plain white sugar cooks the most evenly.

1/3 cup

Local / market

Fish sauce

The backbone. A good Phu Quoc three-crab style has depth without harshness.

3 tbsp

Shallots

Minced fine to melt into the sauce, not sliced.

Garlic

Smashed and minced; goes in with the shallots.

4 cloves

Coconut water

1 cup

Local / market

Black pepper

Coarsely cracked, and a generous hand — it defines the finish.

1 tsp

Local / market

Scallions

Sliced for the top; green parts only.

2 stalks

Straight Answers

Can you make Ca Kho To (Vietnamese Caramelized Braised Fish) in an air fryer? — Yes, with an insert

Not on its own — an air fryer can’t hold a pool of liquid. You can simmer it in an oven-safe dish or a silicone insert made to fit the basket, but the broth won’t reduce or brown the way it does on the stove, and that insert comes out scorching, so use oven mitts. For real depth, a pot on the stove wins.

Can you freeze Ca Kho To (Vietnamese Caramelized Braised Fish)? — Yes

Yes — it freezes well. Cool it fully, portion into airtight containers, and it keeps a few months; thaw in the fridge and reheat gently.

Can you make Ca Kho To (Vietnamese Caramelized Braised Fish) ahead of time? — Yes

Yes — it holds well and often tastes better the next day. Make it ahead and reheat gently before serving.

Is Ca Kho To (Vietnamese Caramelized Braised Fish) gluten-free? — Yes

Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.

Is Ca Kho To (Vietnamese Caramelized Braised Fish) vegan? — No

No — it contains meat, so it isn’t vegetarian or vegan.
