Ingredients for 4 people

- BBQ rub to taste
- 1 lemon

With a pre-made rub, always check the current packaging for dosage, ingredients, and allergens.
Preparing zucchini for the BBQ
- Wash and dry the zucchini.
- Cut them diagonally or lengthwise into slices of about 1 cm.
- Brush the slices thinly with oil.
- Apply the rub just before grilling. If using a salty rub, do not add extra salt until you have tasted it.
- Clean the grate and preheat the BBQ to direct heat.
Long strips are useful if you are worried about small slices falling through the grate. Otherwise, use a grill basket or plancha.
Grilling zucchini on the BBQ
- Place the zucchini over direct heat on the grate.
- Grill the first side for about 2–4 minutes.
- Turn with tongs as soon as the slices have sufficient color and release without forcing.
- Grill the other side for about another 2–3 minutes.
- Remove the zucchini from the BBQ as soon as it is tender but still has a bite.
- Serve with lemon and optionally fresh herbs.
If a slice remains firmly stuck, give it a little extra time or carefully move it to a less hot area. Do not pull hard, as soft zucchini tears easily.

Grilling zucchini without it becoming limp
- Do not cut razor-thin slices.

- Work over sufficient direct heat.
- Do not overcrowd the grate.
- Remove the zucchini before it is completely soft.
- Add acidic dressing and salt only after grilling if you want to maintain more bite.
Zucchini on a plancha or in a grill basket
A plancha or grill basket is useful for cubes and half-moons. Preheat the surface, use little oil, and toss regularly. The pieces will get less pronounced grill marks, but they won't fall through the grate.

Do you need to salt zucchini beforehand?
That is not necessary. Salt can draw out moisture; add it shortly before or after grilling if you want firm slices.
