For me, an autumn veggie roast is fantastic when season kicks in and we see a new range of produce. Root vegetables and squashes enter our supermarkets and this is when I really get excited about cooking.

I didn’t want a vegetable roast that’s just a substitute for meat; I wanted something that anyone can enjoy. I also wanted it to be all about the different layers of flavour coming from each vegetable, followed by wonderful herbs and spices.

Butternut squash and carrot bring both mild sweetness with a little earthiness. The celeriac is there for its nutty, celery flavour which is fantastic for any hearty roast. These mixed with a few herbs and spices, make this dish come alive.

The great thing about making this autumn veggie roast is you use the same mix to make the gravy. This is a really convenient hack that produces a fantastic gravy, which adds more flavour and moisture to the roast. Once you have that sorted, it’s all the trimmings you like as usual.

Autumn veggie roast secret ingredients

There is a couple of surprise appearances in this dish, one being the apple sauce. This adds a little sweetness and it pairs well with the celeriac and sage. I think this adds a lot to the dish and works wonderfully with cabbage on the side.

Now, lets talk about the elephant in the room, shall we? Yes marmite, also known as yeast extract, which really adds that meaty richness that you don’t get from veggies alone. It’s used in a lot of vegetable stocks and with it’s concentrated flavour, it really packs a punch. You may have seen it used in other recipes like our Ultimate Christmas roast potatoes.

Finally the last key ingredient is gram flour! This is what binds all those wonderful veggies together and turns it into more of a joint to carve. It’s used all across India, and other countries, and works so well when making onion bhajis. Last but not least, it adds protein to the dish and is far healthier than using normal flour.
