Vegetarian BBQ — Tips, Techniques, and the Best Alternatives | The Rub Kitchen
Vegetarian BBQ has a bad reputation it doesn't deserve. Not because vegetables are "good enough" as an alternative, but because on the BBQ, they develop their own character that no meat can match. The key: high heat, the right products, and a good rub.
Why does vegetarian BBQ work so well?
Direct fire and high heat do the same to vegetables and plant-based proteins as they do to meat: they caramelize sugars, create Maillard reactions, and give structure to the surface. A well-rubbed piece of eggplant or a thick portobello has just as much bark potential as a chicken piece.
The best products for the BBQ
| Product | Technique | Cooking time | Tip |
|---|---|---|---|
| Eggplant | Direct, high heat | 4–6 min per side | Pat dry, rub generously, don't flip too early |
| Portobello | Direct, gill-side up first | 5–7 min per side | Fills with flavorful juices — don't grill inverted until the end |
| Cauliflower steak | Indirect then direct | 20–25 min total | Cut 2–3 cm thick, cook indirectly until tender, then direct for crust |
| Halloumi | Direct, high heat | 2–3 min per side | Pat dry before grilling, not too long — becomes rubbery |
| Tofu (firm) | Direct | 3–4 min per side | Press for at least 30 min before grilling to remove moisture |
| Seitan | Direct | 3–4 min per side | Marinate beforehand, high heat for crust |
| Corn on the cob | Direct or indirect | 15–20 min | Grilling in husks retains moisture; without husks gives more color |
| Bell pepper | Direct | 8–10 min total | Grill whole, char skin, then peel — sweeter and more tender |

The technique of rubbing vegetables — when to apply, how much, oil vs. no oil — is extensively described on a separate page:
→ Rub on vegetables — how different from meat?
Planning a vegetarian BBQ for a group
- Calculate 300–400 grams raw weight per person for a mix of vegetables and plant-based proteins
- Prepare halloumi and tofu last — they cook quickly and cool down fast
- Use two grill zones: high heat for halloumi and eggplant, indirect zone for cauliflower and corn
- Make a veggie bowl as a base: grilled vegetables over couscous or bulgur with chimichurri
Rub Kitchen tip
The Shawarma BBQ Rub is the best all-rounder for vegetarian BBQ — works on eggplant, cauliflower, halloumi, and tofu. The Korean BBQ Rub adds an umami depth to tofu and portobello that rivals the taste of meat.
