Thai Gaeng Phed Gai with Carolina Reaper

A white bowl of Thai red curry with tender chicken pieces and eggplant in a glossy red-orange coconut sauce, garnished with fresh Thai basil leaves and served alongside jasmine rice.

A fiery red curry with chicken, built on roasted Carolina Reaper peppers, coconut milk, and fish sauce. The heat arrives in waves—sharp from fresh peppers, deep from the paste, and lingering from the long braise. Saucy and spoonable, it mellows slightly as it sits.

Recipe notes

Before you cook

Gaeng phed gai is Thailand's most direct curry: red chillis ground into a paste with aromatics, bloomed in coconut cream, then simmered with chicken until the sauce clings to each piece. This version uses Carolina Reaper peppers for sustained, intense heat that builds rather than merely burns. The curry improves after a day in the fridge, when the chilli intensity settles into a more complex warmth.

Method

How to cook it

Use the step navigator to move around, or stay in cook mode and work top to bottom.

  1. 1

    Step 1 of 5

    Toast and grind the spice base

    Heat a dry skillet over medium-high heat. Add the coriander and cumin seeds; cook for 1–2 minutes, stirring constantly, until fragrant. Tip into a mortar or spice grinder and grind to a coarse powder. Set aside. If using dried Reaper peppers, soak them in hot water for 5 minutes to soften, then drain.

  2. 2

    Step 2 of 5

    Make the curry paste

    In a mortar, pound the softened dried reapers, fresh red chillis, garlic, ginger, and lemongrass into a rough paste, 4–6 minutes. Add the ground coriander and cumin, shrimp paste, and a pinch of salt. Continue pounding until the mixture is relatively smooth but still has visible texture. The paste will be deep red and fragrant.

  3. 3

    Step 3 of 5

    Bloom the paste and chicken

    Heat 2 tablespoons of the coconut milk in a heavy pot or deep skillet over medium-high heat. Add the curry paste and stir constantly for 2–3 minutes until it darkens slightly and smells deeply fragrant. Add the chicken pieces and toss to coat. Cook for another 2 minutes, stirring, until the chicken is partly opaque on the surface.

  4. 4

    Step 4 of 5

    Braise in coconut milk and stock

    Pour in the remaining coconut milk and the stock. Add fish sauce and palm sugar, stirring to dissolve the sugar. Bring to a simmer over medium heat, then reduce to low. Simmer gently, uncovered, for 20–25 minutes, stirring occasionally. If using eggplant, add it in the last 8 minutes. The chicken is done when it is tender and easily broken with a spoon, and the sauce has thickened slightly and coats the back of a spoon.

  5. 5

    Step 5 of 5

    Finish with basil

    Remove from heat and tear the Thai basil into the curry. Taste and adjust with extra fish sauce (for depth) or a pinch of sugar (to balance heat). Serve hot with jasmine rice.

Troubleshooting

Tips that matter

  • Make the curry paste up to 2 days ahead; store in an airtight container in the fridge.

Substitutions and variations

Habanero or Scotch bonnet peppers can replace Carolina Reapers for a slightly lower heat level and fruity notes.
Galangal (1 teaspoon sliced) can be added alongside ginger for a peppery, pine-like note.
Ordinary long red chillis can be used instead of Reapers, but the heat will be significantly lower; use 4–5 fresh and 3–4 dried.
If lemongrass is unavailable, omit it or use a strip of lime zest for a different citrus note.
Beef chuck, pork shoulder, or firm white fish can replace chicken; adjust cooking time accordingly.
For less heat, use 1 dried Reaper and remove the seeds from the fresh chillis, or substitute half the fresh reapers with ordinary long red chillis.
Add 4–5 kaffir lime leaves in the last 5 minutes of cooking for brightness and aromatic depth.
Swap chicken thighs for beef chuck cut into chunks and simmer for 45 minutes to 1 hour until very tender.
Add 1 cup of Thai pea eggplants or baby corn in the final minutes for different texture.

Storage and leftovers

Plan ahead and reheat well

Make ahead

The curry paste keeps for 2 days in the fridge in an airtight container. The finished curry improves after 1 day, as the heat settles and the flavors deepen. Reheat gently over low heat on the stovetop, or in a microwave-safe container at 50% power, stirring occasionally.

Storage

Store the finished curry in an airtight container in the fridge for up to 3 days. The sauce will thicken as it cools; thin with a splash of stock or coconut milk when reheating if needed.

Reheat

Reheat on the stovetop over low heat, stirring occasionally, until simmering. Add a splash of water or stock if the sauce has thickened too much. Do not boil, as this can make the curry taste harsh.

At the table

Serving suggestions

  • Serve over jasmine rice or with sticky rice.
  • Offer condiments on the side: lime wedges, fresh Thai basil, sliced fresh chillis, and fish sauce.
  • Accompany with a cucumber salad (ajad) or blanched leafy greens seasoned with garlic and fish sauce to cool the palate.

FAQ

Common questions

Is this curry really that hot?

Carolina Reaper peppers rank around 1,400,000–2,200,000 Scoville Heat Units. This curry is fiercely hot when made as written, with heat that lingers for 10–15 minutes. If you are not accustomed to extreme heat, start with half the dried Reaper and no fresh Reaper seeds, then adjust upward. The recipe works well at all heat levels.

Can I use red curry paste from a jar instead of making my own?

Yes, but the Reaper heat will not be present. Use 3 tablespoons of shop-bought red curry paste in place of the homemade paste, and add 1 finely minced fresh Reaper pepper directly to the coconut milk in step 4 if you want the extreme heat. This changes the flavor profile but is a time-saving option.

Why use chicken thighs instead of breast?

Thighs remain moist and tender during the 20–25 minute simmer, while breast can dry out and become stringy. If you prefer breast meat, reduce the cooking time to 15–18 minutes and check for doneness earlier.

The curry tastes too hot. What can I do?

Add more coconut milk to dilute the heat while keeping the sauce saucy, or stir in a spoonful of palm sugar and fish sauce to balance the burn. Serve with plain jasmine rice or cucumber salad to cool the palate. Do not add water, as it will thin the sauce and make the heat more pronounced.

Can I freeze this curry?

Yes. Cool the curry completely, then transfer to a freezer-safe container. It will keep for up to 3 months. Thaw in the fridge overnight and reheat gently on the stovetop. The texture remains good, though the herbs will lose some vibrancy.
