Best Keto-Friendly Thai Curry Pastes (2026)

The Hidden Carbs in Thai Curry Paste

Thai curry paste is the soul of any good curry — but it can also be a hidden source of carbs. Many commercial curry pastes contain sugar, flour, or other thickeners that add unnecessary carbohydrates. For keto cooks, choosing the right curry paste is essential.

We tested eight popular Thai curry paste brands across green, red, and Panang varieties to find the best options for keto cooking. Our criteria: carb content, ingredient quality, and — most importantly — authentic Thai flavor.

What Makes a Curry Paste Keto-Friendly?

• No added sugar: Traditional Thai curry paste shouldn't need sugar — the sweetness should come from the natural sugars in shallots and garlic.
• No flour or starches: Some brands use wheat flour or cornstarch as thickeners. These add unnecessary carbs.
• Clean ingredient list: The best pastes contain chili, garlic, shallots, lemongrass, galangal, shrimp paste, and spices — nothing else.

Our Top Pick: Maesri

Maesri Thai Curry Pastes are our top recommendation for keto Thai cooking. These small cans pack intense, authentic flavor with minimal carbs. The ingredient lists are clean, the flavor is restaurant-quality, and the small can size means you're not committing to a giant tub that will lose potency in your fridge.

Maesri offers green, red, yellow, Panang, and Massaman varieties — all keto-friendly. One can makes 2-3 curries, and at around $3.50 per can, it's excellent value.

Runner-Up: Mae Ploy

Mae Ploy is the other heavyweight in Thai curry pastes. The flavor is slightly sweeter than Maesri, which some cooks prefer. The large tub format is economical if you cook Thai food frequently. Just check the label — some Mae Ploy varieties have slightly more sugar than Maesri.

Best Widely Available: Aroy-D

Aroy-D strikes a great balance between authenticity and availability. You can find it in many Asian grocery stores and online. The ingredient lists are clean, and the flavor is solid — not quite as intense as Maesri, but very good for everyday cooking.

Avoid: Thai Kitchen

Thai Kitchen curry pastes are the most widely available in US supermarkets, but they're also the least keto-friendly. The flavor is significantly milder (and sweeter) than authentic Thai brands, and the carb count is higher. If it's your only option, use it — but seek out Maesri or Mae Ploy for better results.
