I held back on the alliteration in that title – after all, I used brown bread, and British vegetables, and considered some bonus bacon. But I figured just the four Bs would be cheesy enough.

Having the time and space to make a proper breakfast feels like a funny little luxury to me. It’s the pottering around in a quiet kitchen, coffee brewing on the table while I whisk ingredients. It’s the joy of keeping one eye on what’s cooking and your mind on how the day might unfold. Breakfast is the reason I dream of having a big kitchen with lots of natural light – as much as I love the challenge of a layer cake or the satisfaction of making a complicated dinner, it’s those mornings sipping sweet tea and flipping pancakes in pyjamas that I fantasise about.

There’s a possibility it’s the wrong week to suggest making breakfast in your oven, but I’ll say this: at least it isn’t waffles. I spent Monday morning sweating away in the kitchen making waffles for breakfast, stood over the iron and in front of the oven keeping them warm and occasionally putting my head into the fridge. Worth it? Yeah, especially when I realised I had leftover crumble topping to throw on them, but I can’t say I’ll be repeating it while the weather is so warm. This recipe means you can pop it in and leave the room to avoid overheating.

It makes the most of leftovers – the half pack of mushrooms, a handful of spinach, a few slices of bread, however much cheese you’ve got kicking about – and uses the vegetables that are in season right now.

We do it like this.

Serves four, or three quite hungry people.

Ingredients

100g mushrooms, sliced
12 asparagus spears, woody ends removed and stems cut into thirds
3 large eggs
375ml milk
1 tsp wholegrain mustard
6 slices old bread, halved diagonally
A generous handful of spinach
Chunk of cheese (as much as you like! I did not get these thighs by measuring cheese)
Seasoning
Butter, for greasing

Method

1. Preheat your oven to 180C, and grease a medium sized baking dish.
2. Over medium heat in a large pan, cook the asparagus pieces and mushroom slices until just softening. As they cook, whisk together the eggs, milk, and mustard.
3. Remove the mushrooms and asparagus from the heat. Dip a slice of bread in the egg mixture, transfer to the baking dish, almost-standing, and layer with mushroom, asparagus and spinach, and repeat. When all the bread and vegetables are arranged in the dish, grate as much cheese as you fancy over the top. Bake for about 30 minutes, or until deep golden brown.
