Some nights call for a tray, a hot oven, and dinner on the table before the kids start circling the kitchen like hungry sharks. This crispy tofu and vegetable sheet pan dinner is my answer to those evenings — golden tofu cubes, blistered vegetables, and a sticky-savoury glaze, all from one tray. I make this at least once a week — it’s become a family favourite, and once you try it, you’ll understand why.

Why You’ll Love This Crispy Tofu and Vegetable Sheet Pan Dinner

• One tray, one wash-up. Everything roasts together, so the dishwasher load stays small and the sink stays clear — a genuine gift on a Tuesday night.
• Genuinely crispy tofu. Pressing and cornflour-dusting gives you edges that crackle rather than soggy cubes that steam in their own moisture.
• Vegetables you already have. The method works with whatever is lurking in the fridge drawer — peppers, broccoli, carrots, courgette, red onion.
• Make-ahead friendly. You can press the tofu and chop the vegetables in the morning, then just assemble and roast at dinnertime.
• Family-approved flavour. The glaze is savoury, lightly sweet, and gently garlicky — familiar enough for picky eaters, interesting enough for the adults.

Ingredients You’ll Need

• 800 g firm or extra-firm tofu, drained
• 2 tbsp cornflour (cornstarch)
• 1 tsp fine sea salt
• ½ tsp cracked black pepper
• 4 tbsp olive oil, divided
• 2 red bell peppers, cut into 3 cm chunks
• 1 large head of broccoli, cut into florets
• 2 medium carrots, sliced into 5 mm rounds
• 1 red onion, cut into thick wedges
• 250 g button mushrooms, halved
• 4 tbsp soy sauce (or tamari for gluten-free)
• 2 tbsp maple syrup
• 1 tbsp rice vinegar
• 3 cloves garlic, finely grated
• 1 tsp grated fresh ginger
• 1 tsp toasted sesame oil
• 1 tbsp sesame seeds, for sprinkling
• 2 spring onions, thinly sliced, to finish

Tip: Weigh your tofu block before you start. A 400 g block serves two generously; for a family of four, buy two blocks or one 800 g block. If you can only find silken tofu, this recipe won’t work — it holds too much water and will fall apart. Firm or extra-firm is essential.

How to Make Crispy Tofu and Vegetable Sheet Pan Dinner

1. Press the tofu properly. Wrap the drained block in a clean tea towel, place it on a plate, and set a heavy frying pan or a couple of tins on top. Leave it for 15 minutes. You’ll know it’s ready when the towel feels damp and the tofu has lost its spongy bounce — it should feel dense and slightly firm to the touch.
2. Heat the oven and prepare the tray. Preheat the oven to 220°C (200°C fan, gas mark 7). Line a large rimmed baking tray with baking paper. Size matters here: use the biggest tray you own, ideally 40 x 30 cm or larger.
3. Cube and coat the tofu. Cut the pressed tofu into 2.5 cm cubes. In a bowl, toss the cubes with the cornflour, salt, pepper, and 1 tbsp of the olive oil. The cubes should look evenly dusted, like lightly floured pastry — no dry patches, no wet spots.
4. Toss the vegetables. In a large bowl, combine the peppers, broccoli, carrots, onion, and mushrooms with the remaining 3 tbsp olive oil. Toss until every piece has a faint sheen. Spread everything across the tray in a single layer, leaving a little space between pieces.
5. Roast the first stage. Slide the tray onto the middle rack and roast for 20 minutes. At this point the vegetables should be softening and the edges of the onion turning translucent, with a faint sweet smell filling the kitchen.
6. Add the tofu and flip. Pull the tray out, give everything a good stir with a spatula, then nestle the tofu cubes among the vegetables. Return to the oven for 15 minutes. Listen for the gentle sizzle — that’s the sign the tray is hot enough.
7. Whisk the glaze. While the tray roasts, stir together the soy sauce, maple syrup, rice vinegar, garlic, ginger, and sesame oil in a small jug. Taste it — it should be salty first, then sweet, with a warm hum of ginger at the back.
8. Glaze and finish. Remove the tray, drizzle the glaze over everything, and toss gently to coat. Return to the oven for a final 5 minutes. The tofu should look deep golden at the corners, and the glaze should have thickened slightly and cling to the vegetables.
9. Rest, then serve. Take the tray out and leave it to sit for 5 minutes. Sprinkle over the sesame seeds and spring onions, then serve straight from the tray.

Tips From My Kitchen

• Press the tofu for the full 15 minutes. Skipping this step is the single biggest reason home cooks end up with soggy tofu. Water trapped inside the block turns to steam in the oven, and steam is the enemy of crisp. The cornflour then has a dry surface to cling to, which is what creates that thin, brittle shell.
• Cut the vegetables to a consistent size. Aim for everything around 3 cm. If your carrots are in thick coins and your peppers in big slabs, the carrots will still be crunchy when the peppers have collapsed. Uniform pieces cook at the same rate, which means no picking through the tray at the end.
• Use a metal tray, not glass. Metal conducts heat far more aggressively, so the bottoms of your vegetables actually brown rather than steam. Glass dishes heat slowly and tend to trap moisture, which softens everything sitting on top of it. If glass is all you have, add 5 minutes to the first roasting stage.
• Don’t add the glaze until the end. Maple syrup and soy sauce contain sugars that burn quickly at 220°C. Adding them in the final 5 minutes gives you a glossy, sticky coating without a bitter, blackened tray. I learned this the hard way after testing this recipe five times — the early-glaze versions always tasted acrid at the edges.
• Prep ahead in stages. Press the tofu and chop the vegetables in the morning, then store the tofu in a sealed container in the fridge and the vegetables in a zip-top bag. At dinnertime you’re looking at 10 minutes of hands-on work before the tray goes in. This is what makes the recipe genuinely weeknight-friendly.
• Double the glaze and keep half back. A little extra glaze drizzled over the finished tray, or over steamed rice on the side, lifts the whole meal. Keep the spare portion in a separate jug so you’re not contaminating it with a spoon that touched raw vegetables.

Common Mistakes to Avoid

• Overcrowding the pan: If the vegetables are piled on top of each other, they release moisture that has nowhere to go, and you end up steaming rather than roasting. Use two trays if you need to — the vegetables should sit in a single layer with visible gaps between them. Cramped trays also cool the oven down, which slows browning further.
• Wrong temperature: Below 200°C, tofu and vegetables will dry out before they colour, giving you pale, leathery results. Above 230°C, the outside burns before the inside cooks through. Stick to 220°C (200°C fan) and trust the timing rather than cranking the heat to speed things up.
• Skipping the rest time: Those 5 minutes off the heat let the glaze set into a sticky coating and allow the vegetables to finish cooking gently in their residual heat. Cut into them immediately and you’ll lose the crisp texture and end up with a tray of soft, lukewarm pieces. Resting also makes the tofu easier to lift without crumbling.

What to Serve With Crispy Tofu and Vegetable Sheet Pan Dinner

• Steamed jasmine or short-grain rice
• Warm flatbreads or roti for scooping
• A sharp cucumber and radish salad with rice vinegar
• Chilled edamame beans with flaky salt
• For a heartier plate, try these roasted Brussels sprouts alongside

Notes

Use the largest rimmed baking tray you own (ideally 40 x 30 cm or larger) so the vegetables roast rather than steam. Press the tofu well for the crispiest result. For gluten-free, use tamari instead of soy sauce.
