Oven-roasted seasonal vegetables tossed in a garlicky lime dressing, echoing Thai som tam flavors without the raw papaya.
This dish adapts the sour-salty-spicy dressing famous from som tam (green papaya salad) and pairs it with roasted vegetables instead of the traditional shredded raw papaya, offering a warm, oven-friendly alternative that still delivers that same punchy Thai flavor profile. It's a home-cooking interpretation rather than a classical dish, built on real nam jim technique: garlic and chile pounded together, then balanced with lime, fish sauce, and palm sugar. Roasting vegetables like eggplant, green beans, and bell pepper at high heat until they char slightly at the edges gives them a smoky quality that stands up well to the sharp dressing, unlike raw vegetables which can taste washed out next to such an assertive sauce. Tossing the vegetables in the dressing while they're still hot from the oven helps them absorb more flavor. Served warm or at room temperature with jasmine rice or grilled protein, this makes a bright, herbaceous side dish or light vegetarian main.
Serves 4
Preheat oven to 220C/425F. Toss eggplant, green beans, and bell pepper with 2 tbsp oil and spread on a sheet pan. Roast 25-30 minutes, turning once, until charred at the edges and tender.
While vegetables roast, pound garlic and chiles together in a mortar and pestle until roughly crushed.
Stir lime juice, fish sauce, and palm sugar into the garlic-chile paste until the sugar dissolves. Taste -- it should be sharply sour, salty, and spicy.
Transfer the hot roasted vegetables to a bowl and toss immediately with the dressing so they absorb the flavor while warm.
Scatter crushed peanuts and cilantro over the top and serve warm or at room temperature.
Roast at high heat so the vegetables char slightly -- this smokiness balances the sharp dressing.
Toss the vegetables while still hot from the oven so the dressing absorbs rather than just coats.
Crush the peanuts coarsely for texture, don't grind them fine.
Add cherry tomatoes to the roasting pan for a closer nod to som tam's tomato addition.
Use roasted sweet potato or squash for a heartier, sweeter version.
Swap peanuts for toasted cashews for a different crunch.
Refrigerate up to 3 days. The dressing keeps the vegetables from drying out, but for best texture, bring to room temperature before serving rather than microwaving.
The dressing here is modeled on the classic nam jim used in som tam, one of Thailand's most iconic dishes, native to the Isan region and built on pounding rather than blending, which is why a mortar and pestle produces noticeably better texture than a food processor.
You can pulse briefly, but a mortar and pestle gives better texture -- it crushes rather than purees, so the garlic and chile stay slightly chunky.
Firmer vegetables that char well work best -- eggplant, green beans, bell pepper, zucchini, or even cauliflower all hold up to the sharp dressing.
It can be adjusted easily -- start with one chile and taste before adding more, since Thai chiles vary a lot in heat.
