Tom Kha (Coconut Soup) With Shrimp: An Easy Culinary Escape

My first encounter with Tom Kha was a revelation. Tucked away in a tiny Thai restaurant in San Francisco, the aroma alone – a fragrant blend of lemongrass, ginger, and coconut – transported me. One spoonful of the creamy broth, punctuated by the sweetness of coconut milk and the subtle heat of chili oil, and I was hooked. It was a culinary hug, comforting and exotic all at once. I’ve been chasing that perfect bowl ever since, and this simplified version brings me right back to that first, unforgettable experience.

• Total Time: 50 minutes
• Servings: 10-12
• Yields: 12 cups
• Dietary Type: Gluten-Free, Dairy-Free (if fish sauce is omitted)

Ingredients

• 4 stalks fresh lemongrass
• 1 piece fresh ginger (2-3 inches)
• 32 ounces chicken broth
• 2 (14 ounce) cans coconut milk
• 1-2 cups sliced mushrooms
• 50-60 raw shrimp (thawed)
• 1-5 teaspoon chili oil (to taste)
• 1 lime, juice of
• 1 tablespoon fish sauce (optional)
• ¾ cup jasmine rice, per person
• 1 cheesecloth (10in x 10in piece)

Equipment Needed

• Large Pot
• Cheesecloth
• Knife
• Cutting Board

Instructions

1. Begin by preparing the jasmine rice. Cook as much as needed according to package directions, as it will be served alongside the soup.
2. Pour the 32 ounces of chicken broth into a large pot. Place the pot over medium heat.
3. Shake the two cans of coconut milk thoroughly to ensure the cream and liquid are well combined. Add the coconut milk to the pot with the chicken broth.
4. Add the sliced mushrooms to the pot. You can adjust the amount of mushrooms to your preference. Some prefer more, some prefer less.
5. Add chili oil now if desired, or at any time during the simmering process. Keep in mind that the longer the chili oil infuses, the spicier the soup will become. Adjust the amount to your personal spice preference. Start with a teaspoon and increase to taste.
6. Prepare the aromatic sachet. Cut the 4 stalks of lemongrass into approximately 1-inch long pieces. Set aside.
7. Thinly slice the 2-3 inch piece of ginger. Set aside.
8. Cut a 10-inch x 10-inch square of cheesecloth. Place the cut lemongrass and sliced ginger into the center of the cheesecloth. Gather the edges and tie the cheesecloth securely to form a sachet.
9. Carefully drop the lemongrass and ginger sachet into the pot with the broth and coconut milk.
10. Allow the soup to simmer for approximately 15 minutes. This is a good time to prepare the shrimp, peeling and deveining them if necessary. Cut the shrimp in half lengthwise.
11. If you haven’t added it already, add the chili oil to the soup.
12. Add the fish sauce, if desired. The fish sauce adds a salty, umami depth to the soup. If you prefer a vegetarian or vegan option, omit the fish sauce.
13. Add the 50-60 raw shrimp to the simmering soup. Cook for approximately 3 minutes, or until the shrimp turn pink and are cooked through. Be careful not to overcook the shrimp, as they will become rubbery.
14. Take the pot off the heat. Carefully remove the lemongrass and ginger sachet from the soup and discard it.
15. Squeeze the juice of one lime into the soup. Stir to combine. Taste and adjust seasoning if necessary.

Expert Tips & Tricks

• For a richer flavor, use full-fat coconut milk rather than light coconut milk.
• If you don’t have cheesecloth, you can simply add the lemongrass and ginger directly to the soup and then strain them out before serving.
• To deepen the flavor, toast the lemongrass and ginger in a dry pan before adding them to the cheesecloth sachet.
• If you prefer a creamier soup, you can blend a portion of the soup (before adding the shrimp) and then return it to the pot.
• Don’t boil the coconut milk, as this can cause it to separate. Simmer gently.
• Taste as you go! Adjust the amount of chili oil, lime juice, and fish sauce to your liking.

Serving & Storage Suggestions

Serve the Tom Kha hot, ladled over a bed of cooked jasmine rice. Garnish with a sprig of cilantro or a wedge of lime for added freshness and visual appeal.

Leftover Tom Kha can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over medium-low heat, or in the microwave. Avoid boiling the soup when reheating. The shrimp may become slightly tougher upon reheating.

It is not recommended to freeze Tom Kha, as the coconut milk can separate and the texture of the shrimp may change.

FAQs (Frequently Asked Questions)

Q: Can I make this ahead of time?
A: You can prepare the soup base (broth, coconut milk, lemongrass, ginger, mushrooms, and chili oil) ahead of time and store it in the refrigerator for up to 2 days. Add the shrimp and lime juice just before serving.

Q: Can I use dried lemongrass instead of fresh?
A: Fresh lemongrass is preferred for its brighter flavor, but you can use dried lemongrass as a substitute. Use about 1 tablespoon of dried lemongrass for every stalk of fresh lemongrass.

Q: How do I adjust the spice level?
A: The spice level is easily adjustable by controlling the amount of chili oil. Start with a small amount and add more to taste. You can also add fresh chilies for extra heat.

Q: My coconut milk separated. What did I do wrong?
A: Coconut milk can sometimes separate if it’s boiled. Make sure to simmer the soup gently over medium-low heat.

Q: What if I don’t have cheesecloth?
A: If you don’t have cheesecloth, you can add the lemongrass and ginger directly to the soup and then strain them out before serving. Alternatively, you can use a fine-mesh sieve or a tea infuser.
