Low Iodine Walnut Pesto Roasted Red Pepper Relish
Smoky, charred red peppers meet a vibrant basil paste and toasty walnuts in a relish that tastes like it belongs on every table. The broiling step is the real magic here — blistering the peppers until they collapse and then letting them steam transforms their raw sweetness into something deeply savory and silky. Managing iodine intake often means scrutinizing condiments and store-bought spreads for hidden additives, but every ingredient in this recipe is straightforward and naturally free of iodized salt or seafood-derived extras. The pesto-style base comes together quickly in a food processor, and folding in the hand-chopped walnuts at the end keeps the texture satisfyingly chunky rather than turning the whole thing into a smooth purée. A hit of fresh lemon juice and red pepper flakes keeps the flavor bright and just a little bold. Spoon it over grilled chicken, stir it into pasta, or pile it onto crusty bread — it works beautifully at room temperature and holds up well, making it a genuinely versatile addition to your low-iodine cooking rotation.

6 servings
For the roasted peppers
- 3 large red bell peppers (about 1 ½ lb total)
- 1 tbsp extra-virgin olive oil
For the pesto-walnut base
- ½ cup raw walnuts
- 1 cup fresh basil leaves, loosely packed
- 1 small garlic clove, roughly chopped
- 3 tbsp extra-virgin olive oil
- 1 tbsp fresh lemon juice
- ¼ tsp red pepper flakes
- ½ tsp salt, plus more to taste
- ¼ tsp black pepper
For serving
- 2 tbsp fresh flat-leaf parsley, finely chopped (optional)
Instructions
- 1
Position an oven rack 6 inches from the broiler element and preheat the broiler to high. Place the whole red bell peppers on a baking sheet, rub them with 1 tbsp olive oil, and broil for 18–22 minutes, turning with tongs every 5–6 minutes, until the skins are deeply charred and blistered on all sides and the peppers have collapsed.
- 2
Transfer the charred peppers to a mixing bowl, cover tightly with a plate or plastic wrap, and let them steam for 10 minutes — this loosens the skins.
