Ingredients
- 150g mixed nuts (walnuts, hazelnuts, almonds), roughly chopped
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 large carrot, grated
- 1 celery stalk, finely diced
- 100g cooked brown lentils (or canned, drained and rinsed)
- 100g cooked quinoa or brown rice
- 75g fresh breadcrumbs (from crusty bread)
- 2 tbsp sunflower oil or olive oil
- 1 tbsp soy sauce or tamari
- 1 tbsp tomato purée
- 1 tsp dried thyme
- 1 tsp dried sage
- 1/2 tsp smoked paprika
- 2 medium eggs, beaten (or flax eggs for vegan option)
- Salt and freshly ground black pepper, to taste
- Fresh parsley, chopped (optional, for garnish)
Instructions
- Preheat your oven to 180°C (350°F) fan or 200°C (400°F) conventional. Grease and line a 900g (2lb) loaf tin with baking parchment.
- Heat 1 tablespoon of oil in a frying pan over medium heat. Add the chopped onion, garlic, carrot, and celery. Cook gently for about 8-10 minutes, stirring occasionally, until the vegetables are soft and fragrant but not browned.
- In a large mixing bowl, combine the cooked lentils, quinoa (or rice), and chopped nuts. Add the cooked vegetables, fresh breadcrumbs, soy sauce, tomato purée, dried thyme, sage, smoked paprika, salt, and pepper. Mix everything thoroughly to combine.
- Allow the mixture to cool slightly before adding the beaten eggs. Stir well to bind all the ingredients together. If the mixture feels too wet, add a little more breadcrumbs; if too dry, a splash of water or vegetable stock will help.
- Transfer the mixture into the prepared loaf tin, pressing down firmly and smoothing the top with the back of a spoon.
- Drizzle the remaining tablespoon of oil over the top to help it crisp up during baking.
- Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and firm to the touch. A skewer inserted into the centre should come out clean.
- Remove from the oven and let the nut roast rest in the tin for 10 minutes before turning out onto a serving plate.
- Garnish with chopped fresh parsley if using, slice, and serve warm.
Tips
- Nut substitutions: Feel free to use pecans, cashews, or pistachios depending on your preference or what you have on hand. Toasting the nuts beforehand will enhance their flavour and texture.
- Binding alternatives: For a vegan-friendly roast, replace eggs with flax eggs (1 tbsp ground flaxseed mixed with 3 tbsp water per egg, left to gel for 5 minutes) or use a commercial egg replacer.
- Adding moisture: If your mixture feels dry, a splash of vegetable stock or a little olive oil can help keep the roast moist without making it soggy.
- Common mistake: Avoid overcooking the vegetables at the start; softening them gently preserves their flavour and prevents the final roast from becoming dry.
Serving Suggestions
This nut roast is delicious served hot with traditional roast dinner sides such as roast potatoes, steamed green vegetables (like broccoli or green beans), and a rich vegetarian gravy. It also pairs wonderfully with cranberry sauce or a tangy tomato chutney for extra flavour contrast. For a lighter option, slice the nut roast and serve it on toasted sourdough with a fresh salad and a dollop of herby yogurt or vegan mayonnaise.
Variations
While this recipe avoids mushrooms, you can easily add other ingredients to vary the flavour and texture. For example, finely chopped roasted red peppers or sun-dried tomatoes add sweetness and depth. Incorporating cooked sweet potato or butternut squash purée can make the roast softer and slightly sweeter. Different herbs like rosemary or oregano can be used instead of or alongside thyme and sage for a different aromatic profile. For extra protein, add cooked chickpeas or black beans, mashed lightly before mixing.
Storage and Reheating
Once cooled completely, wrap the nut roast tightly in cling film or foil and store it in the refrigerator for up to 3 days. It can also be frozen for up to 1 month; thaw overnight in the fridge before reheating. To reheat, slice the nut roast and warm in a preheated oven at 160°C (320°F) for 15-20 minutes until heated through, or microwave individual slices for 2-3 minutes on medium power. Avoid reheating multiple times to maintain texture and food safety.
Frequently Asked Questions
Can I make this nut roast vegan?
Yes, simply replace the eggs with flax eggs or a commercial egg replacer. Use a vegan-friendly binding agent to ensure the roast holds together. Also, check that any added sauces like soy sauce or tomato purée are free from animal products.
What if I don’t have quinoa or brown rice?
You can substitute with other cooked grains such as bulgur wheat, barley, or even couscous. The key is to use a grain that holds moisture well and adds texture without making the mixture too wet.
Can I prepare the nut roast in advance?
Absolutely. Prepare the mixture up to a day ahead and keep it covered in the fridge. Bake it fresh before serving for best texture and flavour. Alternatively, bake it fully, cool, and reheat when needed.
How do I prevent the nut roast from being crumbly?
Ensure you use enough binding agents like eggs or flax eggs, and avoid overcooking the vegetables so they retain moisture. Adding some cooked grains and breadcrumbs helps absorb excess moisture and bind the mixture firmly.
Can I add cheese to this recipe?
Yes, adding grated hard cheese such as cheddar or parmesan can add richness and help bind the roast. Mix about 50g of cheese into the mixture before baking. For a vegan alternative, use a plant-based grated cheese substitute.
Why avoid mushrooms in this recipe?
Mushrooms are common in many nut roast recipes for their meaty texture and umami flavour, but some people dislike their taste or texture, or have allergies. This recipe uses a combination of nuts, lentils, and grains with herbs and spices to create a flavourful roast without mushrooms, making it more accessible and appealing to a wider audience.
This nut roast is a reliable, tasty vegetarian centerpiece that works for holiday feasts or cozy dinners. With simple ingredients and straightforward steps, it’s a great way to enjoy a mushroom-free alternative inspired by Jamie Oliver’s style but adapted for your kitchen.
