Thai cuisine is a vibrant and flavorful fusion of sweet, sour, salty, and spicy, but many traditional recipes feature high-carb ingredients like rice, noodles, and sugary sauces. However, a low-carb lifestyle doesn't mean you have to forgo the rich, aromatic flavors of Thai food. With the right knowledge, you can easily find or create delicious and healthy low-carb Thai meals.
Naturally Low-Carb Thai Dishes
Some of the best low-carb Thai options are naturally so, focusing on fresh vegetables, herbs, and protein without a rice or noodle base.
Tom Yum Soup
Often cited as a top keto-friendly Thai food, Tom Yum is a spicy and sour soup that is packed with flavor and low in carbs. Its base consists of lemongrass, galangal, kaffir lime leaves, and a protein like shrimp (goong) or chicken (gai). As a naturally thin soup, it's typically served without added carbs. Ask for extra mushrooms and a protein to make it even more filling.
Larb Salad
Larb is a zesty, savory minced meat salad that is a protein-packed and naturally low-carb choice. Traditional Larb consists of ground chicken, pork, or beef seasoned with fish sauce, lime juice, chili flakes, mint, and toasted rice powder. To keep the carbs to a minimum, simply request it without the toasted rice powder and enjoy it with large lettuce leaves for wrapping.
Thai Beef Salad (Yum Nua)
Similar to Larb, a spicy Thai Beef Salad is a refreshing and protein-rich option. It typically combines grilled, sliced beef with a mixture of fresh vegetables like cucumber, onion, and cilantro, dressed in a tangy lime-based sauce. The key is to confirm there is no sugar added to the dressing. For a restaurant version, ensure it is served without any noodles.
Making Stir-fries and Curries Low-Carb
While stir-fries and curries often contain hidden sugars and are traditionally served with rice, they can be easily adapted for a low-carb diet.
-
Modify Sauces: The sweetness in Thai sauces often comes from added sugar, palm sugar, or tamarind paste. When ordering a stir-fry, ask the chef to go light on the sauce or specify "no sugar added." For curries, the creamy, full-fat coconut milk base is perfectly keto-friendly, so the main concern is the sweetness and thickeners like cornstarch. Request a less sweet curry or opt for a red or green curry with low-carb veggies.
-
Swap the Carbs: The biggest carbohydrate culprit is the side of rice. Instead, ask for extra vegetables, or if available, request cauliflower rice or shirataki noodles. Alternatively, simply enjoy the stir-fry or curry as is, focusing on the protein and vegetable components.
Keto-Friendly Curries
- Green Curry (Kaeng Keow Wan): Made with coconut milk and green chilies, a green curry is a flavorful and fatty option that can be made low-carb by omitting high-starch vegetables and serving it without rice.
- Red Curry (Kaeng Phet): Red curry, based on dried red chilies, also provides a rich coconut milk base and is an excellent low-carb choice when paired with chicken or beef and served with extra low-carb vegetables.
Low-Carb Vegetable Additions
For any Thai dish, especially stir-fries and curries, boosting the vegetable content is a great way to increase nutrition and satiety without adding carbs. Ask for extra helpings of these low-carb vegetables:
- Bok Choy
- Broccoli
- Green Beans
- Mushrooms
- Bell Peppers
- Bamboo Shoots
- Eggplant
- Cabbage
