Charred Lemon, Caper and Parsley BBQ Dip for Chicken
A sharp, briny BBQ dip built around grilled lemon, capers, parsley and olive oil. It’s loose, glossy and savoury, made for spooning over smoky chicken thighs, wings or skewers. The charred citrus gives depth, while capers add salty bite and parsley keeps everything fresh.
Ingredients
- 2 large unwaxed lemons halved
- 35 g capers drained and roughly chopped
- 25 g fresh flat-leaf parsley finely chopped
- 1 small garlic clove grated
- 60 ml extra virgin olive oil
- 1 teaspoon Dijon mustard
- ½ teaspoon caster sugar
- ¼ teaspoon fine sea salt plus more to taste
- ½ teaspoon cracked black pepper
- 1 tablespoon cold water only if needed
- ½ teaspoon finely chopped green chilli optional, for a sharper bite
Instructions
Char the lemons
- Place the lemon halves cut-side down over medium-high BBQ heat. Grill for 3 to 5 minutes until the cut faces are dark in patches, glossy and slightly softened. You want colour, not burnt bitterness. Lift them off with tongs and leave them for 2 minutes, just until they’re cool enough to handle. Warm lemon juice comes out more easily, and the flavour is softer than raw lemon.
Chop the capers and parsley
- Roughly chop the drained capers so some are almost minced and some stay chunky. Finely chop the parsley, including the tender stems. The stems have plenty of flavour and give the dip a nice green snap. Tip both into a small mixing bowl.
Squeeze and scrape the lemons
- Squeeze the charred lemons into the bowl. Use a teaspoon to scrape a little softened lemon flesh from the cut sides too. Avoid digging too deep into the white pith, as it can make the dip too bitter. You should have around 45ml to 60ml juice and pulp. If your lemons are very juicy, start with most of it, then adjust at the end.
Build the dip
- Add the grated garlic, Dijon mustard, olive oil, sugar, sea salt and black pepper. Stir with a fork until the mustard loosens into the oil and lemon juice. It won’t become thick like mayo, but it should look glossy and lightly held together. Taste it on a bit of cooked chicken if you can, not just from the spoon. BBQ smoke changes how sharpness lands.
Adjust the texture
- If the dip feels too intense, add 1 tablespoon of cold water. If it tastes flat, add a pinch more salt. If it needs more lift, squeeze in a little raw lemon juice or add another teaspoon of chopped capers. Serve at room temperature, spooned over grilled chicken or placed on the table as a sharp BBQ dip.
Notes
Use unwaxed lemons if you can, because you’ll be working close to the skin and pith once they’re charred. I like lemons that feel heavy for their size. They usually give more juice, and they hold up better when placed cut-side down on the grill. If the lemons are tiny, use three instead of two.
The capers matter more than they look. They bring salt, acidity and a tiny pop of texture, so this dip doesn’t turn into a flat lemon-oil dressing. I use small capers in brine, not salted capers, because they’re easier to balance quickly while the BBQ food is finishing.
Parsley keeps the dip fresh, not fancy
Flat-leaf parsley is the one I reach for here. Curly parsley can work, but it needs finer chopping and a little more olive oil to soften its texture. Don’t blitz the parsley into a paste unless you want the dip smoother. I prefer a rough chop, so every spoonful gets green flecks, lemon pulp and caper pieces. Dijon mustard is doing quiet work. It helps the olive oil and lemon juice hold together just enough, while adding a mild heat. The sugar isn’t there to make the dip sweet. It rounds off the bitter edge from the charred lemon and stops the acidity from feeling scratchy. Tried this recipe?Let us know how it was!
