Preparation and assembly
- Start the main dish and longer roasting first; prepare sides while it cooks. If components need different oven temperatures, cook them sequentially and keep the main covered and warm. Use the quantities listed for each component.
- Roasted celeriac: Peel the celeriac and cut into 3 cm thick steaks. Coat with oil and salt.
- Roasted celeriac: Cover on a baking tray and roast at 190°C for 40 minutes; uncover for another 20–25 minutes, until a knife slides easily through the centre.
- Potato mash: Peel potatoes, cut evenly and boil for 20–25 minutes until tender. Drain and steam-dry in the warm pan for one minute.
- Potato mash: Rice the potatoes, then stir in hot soy milk, oil and salt by hand. Do not use a blender, which makes mash gluey.
- Onion gravy: Cook thinly sliced onions in oil over medium-low heat for 20–25 minutes until deep golden.
- Onion gravy: Stir in flour for one minute, then gradually add stock. Add soy sauce and vinegar and simmer for 10 minutes until thickened.
- Divide the main dish and sides into equal portions. Serve sauces separately and slice rested dishes only after their stated resting time.
Beginner-friendly tips
Read these three practical tips before cooking. Check how the food looks and feels, not just the clock.
- Preheat the oven fully and spread the pieces in a single layer with gaps. An overcrowded tray steams vegetables instead of roasting them.
- At the end, pierce the thickest piece with a fork: the centre should be tender and the edges lightly browned. If firm, roast a few minutes longer.
- If the top darkens too fast, move the tray down or lower the temperature slightly. If pale, roast uncovered for the final minutes.
Tip
Prepare fillings and sauces first for a calmer lunch. Loaves and layered bakes need resting for neat slices. Time is an estimate for a home kitchen; one oven may require longer.
