Vegetarian Shrooms on Toast

Devilled food dates back to the late 1700’s and has become synonymous with generously spiced dishes.

These devilled mushrooms on toast are one of many variants that I have been consuming a great deal of late.

My version is a simple vegetarian dish that I regularly eat for any of the three main meals of the day. They are superb for a breakfast weekend treat, they make a superb lunch and a great light dinner dish.

Devilled eggs are arguably the most “popular” in modern parlance, but I love dishes like devilled kidneys, devilled sausages and devilled mackerel.

My devilled sauce for this recipe is very much influenced by Mrs Beeton’s recipe from the early 20th century.

It contains mustard, a vegetarian substitute for Worcestershire sauce, vinegar and a splash of Tabasco sauce.

Frequently Asked Questions

What is Henderson’s relish?

Henderson’s relish is a condiment that is in some ways similar to Worcestershire sauce. However, it has a very different flavour.

Unlike Worcestershire sauce, it does not use anchovies as a base. It is vegetarian, vegan and gluten-free, and it is delicious.

I use it here as I want to keep this recipe vegetarian friendly, you could use Worcestershire sauce, it give a different flavour and both options are delicious.

Do I have to use English mustard?

Yes, you can use other mustards. English mustard has the biggest bite of the yellow mustards, you can temper it a little by using German mustard.

Both American mustard and Dijon mustard are tasty and carry far less mustard heat.

Is the brandy essential?

No, however, it does add a lovely complexity to the dish, but it can be omitted and the dish will still taste great.

I do not like brandy as a drink but usually have a small bottle around for cooking. I use it in dishes like my Instant Pot beef bourguignon and steak pasta with a Diane sauce.

Do I have to use portobello mushrooms?

No, you can use whatever mushrooms you can get your hands on. Baby button mushrooms as superb and you could use them to turn this into an appetiser rather than main meal.

Serving Suggestions

I like to serve my devilled mushrooms on toast with eggs, here they are pictured with a fried egg. Now for me, a fried egg needs a nice runny yolk and a frilly crispy skirt.

But I am not a food zealot that claims any way of enjoying food is more valid than another. So cook your fried egg as you like it!

If you wanted a slightly larger meal then scrambled eggs make a wonderful addition. I would put the eggs on the toast first if I were to do that.

You can also add poached eggs if you have good fresh eggs!

Bacon and sausages also make wonderful additions to this recipe.
