Vietnamese Sour Soup (Canh Chua)

Canh Chua is an iconic Vietnamese Sour Soup, loved for its broth that’s sweetened by pineapple and garnished with fresh herbs! This version comes with juicy fish steaks cooked for just long enough to fall apart in your mouth. It’s excellent for an easy dinner yet exciting enough for celebrations!

A household favorite

You know you’re truly diving into Vietnamese cuisine when you’ve tried Canh Chua. Ask any Vietnamese family and they’ll confidently say that it’s a dinner time regular!

And while that might be the case, don’t be fooled by the simplicity – Canh Chua is actually a super popular choice for family celebrations!

It’s is often enjoyed with Cá Kho Tộ (Braised Fish), a classic that complements the perfect balance of sweet, salty and sour in a pot of Vietnamese Sour Soup.

But the deeply tantalising flavors aren’t what keep me going back for more each time. If you’ve ever had this family favorite before, you’ll know what I mean when I say that the bạc hà (elephant ear plant) is the BEST part.

Why? Because it acts like a crisp and delicious sponge, soaking up every drop of tangy sweetness.

Then there’s the fish. Oh. My. Juicy grouper steaks taste fresh and light, yet are thick enough to make each bite incredibly satisfying.

And even if you’ve finished all the toppings in your bowl, it doesn’t end there. You can mix in a scoop of rice and enjoy it like a true Vietnamese!

Which fish do I use?

We love using the meatier types like grouper, cod, catfish and salmon, but Grandma has used tailor in the past. Some families also like to make it just the head and bones of fish like we do in our Chinese Fish Soup.

You’ll find that flesh closer to the bone is silkier than just steaks, but it really comes down to your personal preference!

Why this recipe works

• Fresh pineapple and tomatoes adds a natural zest to the broth.
• Adding fried garlic keeps the flavors wildly fragrant.
• Using fish steaks means you can enjoy it two ways – as a meal OR a soup.

Tips for the best results

• Cook the fresh ingredients just before serving. Aside from the elephant ear plant, all the other toppings will get very soft if cooked for too long. Leave them aside until you’re ready to serve.
• Use a stock. Vegetable or chicken will work well to give the Vietnamese Sour Soup an extra layer of flavor.
• Source fresh toppings. While canned pineapple is available, anything you can get fresh is going to give this dish its crisp taste.

Make it a Vietnamese feast!

• Start with the ever-popular street food Bánh Tráng Trộn (Vietnamese Rice Paper Salad).
• No party is complete without a plate of Fish Sauce Chicken Wings.
• Serve rice or noodles with a side of Gà Xào Sả Ớt (Spicy Lemongrass Chicken), Thịt Kho (Vietnamese Braised Pork Belly and Eggs in Coconut Water) and Stir Fried Water Spinach with Shrimp Paste.
• An Avocado Smoothie (Sinh Tố Bơ) will help keep everyone happy.
