Equipment

• Large roasting tray
• Mixing bowls
• Medium saucepan
• Wooden spoon
• Masher or potato ricer
• Frying pan
• Baking dish for stuffing
• Sharp knife and chopping board

Instructions

1. Prepare the vegetables: Preheat your oven to 200°C (180°C fan). In a large bowl, toss the carrots, parsnips, sweet potato, butternut squash, red onion, and mushrooms with olive oil, smoked paprika, dried thyme, salt, and pepper. Spread evenly on a roasting tray.
2. Roast the vegetables: Place the tray in the oven and roast for 35-40 minutes, turning halfway through, until vegetables are tender and caramelized.
3. Make the stuffing: Heat olive oil in a frying pan over medium heat. Add the chopped onion and garlic, cooking until softened (about 5 minutes). Add the mushrooms and cook until they release their moisture and start to brown, about 7-8 minutes.
4. Combine stuffing ingredients: Remove from heat and stir in breadcrumbs, walnuts, parsley, soy sauce, and seasoning. Mix well until the mixture holds together when pressed. Transfer to a greased baking dish.
5. Bake the stuffing: Place the baking dish in the oven alongside the vegetables and bake for 20-25 minutes, until golden on top.
6. Prepare mashed potatoes: While vegetables and stuffing roast, boil potatoes in salted water until tender (about 15-20 minutes). Drain and mash with butter and milk until smooth and creamy. Season to taste.
7. Make the gravy: In a saucepan, heat olive oil over medium heat. Stir in flour and cook for 1-2 minutes to form a roux. Gradually whisk in vegetable stock, soy sauce, and sage. Simmer for 5-7 minutes until thickened. Season with salt and pepper.
8. Serve: Arrange roasted vegetables and stuffing on plates, add a generous scoop of mashed potatoes, and drizzle with warm gravy.

Tips & Variations

For extra flavor, marinate the vegetables in a mix of balsamic vinegar, garlic, and rosemary before roasting.

Feel free to swap the stuffing ingredients to suit your preferences. For example, try adding cranberries or apricots for a sweet note, or replace walnuts with pecans or pine nuts.

If you want to add protein, serve your roast with crispy roasted chickpeas or a lentil loaf. For a gluten-free option, use gluten-free breadcrumbs or substitute with cooked quinoa.

Don’t forget to baste your vegetables halfway through roasting with any pan juices to keep them extra moist and flavorful.
