SOMETHING FOR NOTHING : Roasted Red Onion & Basil Mushrooms

I had the idea for these amazing mushrooms the other day while looking for a tasty accompaniment to have with my Aubergine Kievs.
(Click HERE for recipe).
I happened to have some large portabello mushrooms and a couple of red onions that needed using up, and I always have a large basil plant on my kitchen windowsill...
1-2-3 and these babies were invented!
You only have to look at the vibrant colours in this dish to know it's going to be good for you....and the flavours-nothing clever, very simple but totally and utterly delicious! Somehow, these 3 ingredients combine to bring out the best in each other.
I'll be serving these with grilled meats, fish and vegetarian dishes all year round.
They take 1 minute to make
and 25 minutes to bake.

They are 0pp/approx.50kcal each


You Will Need : (Per serving)

1 large open mushroom.
(Portabello have a fantastic flavour)

1 small red onion
Generous handful of fresh basil leaves
Dried mixed Italian herbs
1/2 teaspoon of low salt soy sauce
Black pepper
Frylight oil

(You could use 1 teaspoon olive oil for 1pp/40kcal)


Preheat the oven to 200 degrees centigrade.

Quarter the onion and pop with plenty of fresh basil into a food processor with some dried herbs. Blitz until roughly chopped and chunky.

Heap the onion mixture generously into the mushroom in a thick layer. Mist lightly with Frylight or olive oil. Sprinkle a few drops of soy sauce on the top.

Roast for 25 minutes until the top is crisp and golden.
Season with freshly ground black pepper and garnish with a single fresh basil leaf.

Serve with your chosen main dish.


Purple power!



Serve as a starter with a simple salad.


Experiment with ingredients such as garlic, pine kernels, sage, ground nuts.
