Grilled Thai Chicken Thigh Tom Yum: Smoky, Aromatic GLP-1 Soup

Each bowl of this grilled Thai tom yum delivers 34 grams of protein from boneless, skinless chicken thighs, with only 338 calories per generous serving. The chicken is grilled first — a step that adds a layer of charred, smoky flavor you simply cannot get from poaching or simmering alone. The broth provides B vitamins and electrolytes from the aromatics, while mushrooms and tomatoes round out the bowl with gentle fiber and micronutrients.

The flavor here is layered and bright. Lemongrass and galangal form the aromatic backbone, while lime juice and a touch of fish sauce create that signature Thai sweet-sour-salty balance. Grilling the chicken separately means each piece has caramelized edges that hold up beautifully when sliced and settled into the hot broth, adding a smokiness that traditional tom yum lacks.

This soup format is particularly well-suited for people on Mounjaro or Ozempic who find large, dense meals difficult to finish. The clear broth is hydrating and easy to sip, while the sliced chicken provides satisfying protein in manageable bites. You control the ratio — more broth on low-appetite days, more chicken when you need the protein.

Why This Works on GLP-1

With 34 grams of protein per serving, this soup provides roughly half the daily minimum that most dietitians recommend for people on GLP-1 medications. Adequate protein intake is critical during GLP-1-assisted weight loss because these medications can cause muscle loss alongside fat loss if protein intake drops too low. Chicken thighs are slightly higher in fat than breast meat, but that modest fat content — 16 grams per serving here — helps you absorb fat-soluble vitamins and keeps the meat tender and satisfying rather than dry and chalky.

The broth-based format is gentle on a digestive system slowed by GLP-1 medication. Unlike heavy cream soups or stews thickened with flour, tom yum sits light in the stomach. The ginger and galangal in the broth have well-documented anti-nausea properties, which is a genuine benefit for Wegovy or Zepbound users experiencing gastrointestinal side effects in the early weeks of treatment.

Mushrooms contribute selenium and B vitamins with virtually no caloric cost, while cherry tomatoes provide lycopene and a touch of natural sweetness. The entire bowl is naturally gluten-free, and the low carbohydrate count of 14 grams per serving means minimal blood sugar impact — helpful for those using GLP-1 medications partly for metabolic health.

Ingredients (serves 4)

For the grilled chicken:

• 1½ lb (680g) boneless, skinless chicken thighs
• 1 tablespoon avocado oil
• ½ teaspoon kosher salt
• ¼ teaspoon white pepper

For the tom yum broth:

• 6 cups (1.4L) low-sodium chicken broth
• 3 stalks lemongrass, bottom 4 inches only, smashed and cut into 2-inch pieces
• 1-inch (2.5cm) piece galangal or fresh ginger, sliced thin
• 4 makrut lime leaves, torn (or zest of 1 lime)
• 2 Thai bird's eye chilis, lightly crushed (reduce to 1 or omit for sensitive stomachs)
• 2 tablespoons fish sauce
• 1 tablespoon lime juice (about ½ lime)
• 1 teaspoon coconut sugar or light brown sugar

For the soup vegetables:

• 8 oz (225g) mixed mushrooms (oyster, shiitake, or white button), sliced
• 1 cup (150g) cherry tomatoes, halved
• 1 small zucchini (about 6 oz / 170g), halved lengthwise and sliced into half-moons

For serving:

• Fresh cilantro leaves
• 1 lime, cut into wedges
• Thinly sliced scallions

Instructions

Grill the chicken:

1. Preheat a grill or grill pan over medium-high heat. Lightly oil the grates or pan. Pat the chicken thighs completely dry with paper towels — this step is what creates proper char marks rather than steaming the surface.
2. Rub the thighs with avocado oil, salt, and white pepper. Place on the grill and cook undisturbed for 5–6 minutes per side until the internal temperature reaches 165°F (74°C) and you have distinct grill marks.
3. Transfer the chicken to a cutting board and let it rest for 5 minutes. Slice each thigh crosswise into ½-inch strips. Resting allows the juices to redistribute so they stay in the meat rather than running into the broth.

Build the broth:

4. While the chicken grills, combine the chicken broth, lemongrass, galangal, lime leaves, and chilis in a medium pot. Bring to a boil over high heat, then reduce to a steady simmer for 8–10 minutes. This infuses the broth with the aromatics — longer simmering means more flavor.
5. Use a slotted spoon or small strainer to remove the lemongrass stalks, galangal slices, lime leaves, and chili pieces. These are flavoring agents, not meant to be eaten.

Finish the soup:

6. Add the sliced mushrooms and zucchini to the strained broth. Simmer for 3–4 minutes until the mushrooms are tender and the zucchini is just cooked through but still has some bite.
7. Add the cherry tomatoes and cook for 1 minute — you want them warmed and slightly softened, not collapsed into mush.
8. Remove from heat. Stir in the fish sauce, lime juice, and sugar. Taste and adjust: more fish sauce for salt, more lime for brightness, more sugar to round off any sharpness.

Assemble and serve:

9. Divide the broth and vegetables among four bowls. Arrange the sliced grilled chicken on top so the char marks are visible. Garnish with fresh cilantro, sliced scallions, and a lime wedge on the side.

Practical Notes

Make the broth ahead for faster weeknight assembly. The infused tom yum broth can be prepared up to 3 days in advance and stored in the refrigerator. On cooking night, reheat the broth, add the vegetables, and grill the chicken — you will have dinner on the table in under 15 minutes.

Use a grill pan if you do not have an outdoor grill. A cast iron grill pan over high heat produces excellent char marks and smoky flavor indoors. Open a window or turn on the range hood fan, as the chicken will produce some smoke. A regular cast iron skillet works too — you lose the grill marks but keep the sear.

Store leftovers with broth and chicken separated. The grilled chicken maintains its texture much better when stored apart from the liquid. Refrigerate both in airtight containers for up to 4 days. To reheat, warm the broth and vegetables first, then add the sliced chicken just before serving so it heats through without overcooking.

Start with half a bowl on high-nausea days. If you are in the early weeks of GLP-1 treatment and your appetite is very low, ladle a smaller portion with extra broth and less chicken. Sipping warm broth between bites of chicken helps maintain hydration and calorie intake without overwhelming a sensitive stomach.

Swap the protein to keep the recipe in rotation. This tom yum base works equally well with grilled shrimp (5–6 minutes total grill time), firm tofu pressed and grilled, or even thinly sliced grilled flank steak. The broth and vegetable base stays the same — only the protein and its grill timing changes.
