Cá Kho Tộ has been part of Vietnamese cuisine for generations and is often considered one of Vietnam’s national dishes. While the basic ingredients are simple, perfecting the technique of caramelization and developing the complex layers of flavor are what set Cá Kho Tộ apart.

Ingredients & Preparation

The beauty of Cá Kho Tộ lies in its short, high-impact ingredient list. Here’s what you’ll need:

Ingredients

• 1 1⁄2 lbs firm white fish fillets (catfish, tilapia, bass, or snapper work well), cut into 2-inch chunks
• 1⁄4 cup vegetable oil
• 1⁄3 cup sugar
• 1⁄4 cup nuoc mam (Vietnamese fish sauce)
• 2 tbsp minced garlic
• 2 tsp shrimp paste
• 1 yellow onion, diced
• 2 cups carrot, cut into chunks
• 1 bell pepper, sliced
• 15 curry leaves
• 2 sprigs cilantro
• 2 sprigs green onion
• Salt and pepper to taste

Preparing the Ingredients

• Fish: Pick a firm, flaky white fish like catfish, tilapia, bass or snapper. Make sure the fillets are fresh with no discoloration. Pat dry and cut into 2-inch chunks.
• Vegetables: Prep the onion, carrot, bell pepper, cilantro, and green onion. Cut any large pieces down to bite-sized chunks.
• Sauce ingredients: Combine the fish sauce, sugar, shrimp paste, and garlic in a small bowl. Stir to dissolve the sugar and shrimp paste.
• Aromatics: Wash the curry leaves thoroughly. Pick the leaves from the cilantro and green onion sprigs.

Cooking Instructions

Now we’re ready to cook! Follow these steps closely to build flavor layer by layer:

Step 1 – Caramelize the Sugar

Caramelizing the sugar is the most important step for creating the signature sauce. Here’s how:

• Heat 1⁄4 cup vegetable oil in a large skillet or wok over medium-high heat. Add the sugar and cook, stirring constantly, for 5-7 minutes until the sugar melts and caramelizes into a dark amber color.
• Once the sugar starts to caramelize, stir vigorously to prevent burning. If sugar clumps form, crush them against the side of the pan with a wooden spoon.
• When the caramel has reached a dark amber shade, remove pan from heat and carefully pour the fish sauce mixture into the caramel. It will bubble rapidly.
• Stir until well combined, then return pan to low heat. This forms the base caramel sauce.

Step 2 – Simmer the Fish

Now it’s time to add the main ingredients:

• Raise heat to medium-high and add the fish chunks in a single layer. Cook for 2 minutes until the fish begins to firm up.
• Next, add the onion, carrot, bell pepper, curry leaves, cilantro, and green onion. Stir well to incorporate.
• Allow mixture to simmer, stirring occasionally, for 7-10 minutes until fish is cooked through and vegetables have softened.
• If the sauce evaporates too quickly, lower heat to medium. Add a splash of water if it gets too thick.

Step 3 – Finish with Fresh Herbs

The final step adds brightness with fresh herbs:

• Once fish and vegetables are cooked through, remove pan from heat and stir in several sprigs of cilantro and green onion. This adds a fresh pop of flavor.
• Taste the sauce and season with salt, pepper, or more fish sauce if desired. The sauce should taste rich, sweet, salty, and umami.
• Transfer Cá Kho Tộ to a serving platter or individual plates. Garnish with extra cilantro leaves and green onion. Enjoy immediately while hot.

Tips and Variations

Cá Kho Tộ is delicious as written, but you can adapt it to your tastes:

Cooking Tips

• Use a heavy-bottomed pan like cast iron for even caramelization. Light aluminum pans can cause the sugar to burn.
• Control the heat carefully when caramelizing. Too high heat will burn the sugar. Too low and it won’t caramelize properly.
• Let sugar fully dissolve when making the caramel to prevent a grainy texture.
• Add a touch of vegetable oil if the caramel is too thick once finished.

Ingredient Variations

• Substitute catfish, tilapia, striped bass, trout, or any other firm white fish. Avoid oily fish like salmon or mackerel.
• Swap different vegetables like squash, eggplant, mushrooms, or green beans. Just adjust cooking times.
• For a vegetarian version, use pressed tofu instead of fish.
• Add chiles, lemongrass, ginger, lime juice, or basil for extra flavor.
• For texture, add boiled eggs, fried tofu, or toasted peanuts on top.

Serving & Enjoyment

Here are some final tips for savoring this Vietnamese favorite:

Serving Suggestions

• Serve Cá Kho Tộ with steamed jasmine rice to soak up the sweet-salty sauce.
• Fried eggs, stir-fried greens, and a crunchy vegetable like kimchi also pair well.
• Present family-style in the cooking pan for a communal feel.

Enjoyment

• Cá Kho Tộ is best when fresh and steaming hot. The textures and flavors meld together beautifully.
