Ingredients and substitutions for mushrooms on toast with poached egg
See recipe card for quantities.
- Mushrooms – Any mushrooms work here – chestnut, button, portobello, or a mix if you're feeling fancy. The key is getting them golden so all that umami comes through. Swap for oyster mushrooms if you want extra "cowboy" vibes.
- Butter – Butter gives the mushrooms richness and helps them caramelise. Use olive oil if you prefer, or a mix of both for flavour and browning
- Garlic – Fresh garlic brings the whole dish to life. Garlic powder works in a pinch, but fresh is definitely worth it
- Soy Sauce – This is your umami booster. Tamari works for a gluten‑free option, and a splash of dark soy gives deeper colour.
- Worcestershire Sauce – Adds savoury depth and a little tang. If you need a vegetarian alternative, use a veggie Worcestershire or a dash of balsamic vinegar.
- Egg – A poached egg is classic here – that runny yolk becomes the sauce. Fried or soft‑boiled eggs also work if poaching feels like too much stress.
- Chives – They add a fresh, oniony pop. Spring onions or parsley make great substitutes.
- Bread – Sourdough, farmhouse, ciabatta – anything chunky enough to hold those juicy mushrooms. Toast it well so it can soak up all the flavour
- Lamb's Lettuce / Watercress – A handful on the side (or under the mushrooms) adds freshness and a little peppery bite. Spinach or rocket work just as well.
What equipment will you need to make Mushrooms on toast with poached egg?
- Frying pan – Every kitchen needs a good frying pan and for this recipe its essential. Click the link for my recommendation. It has a metal handle so the whole pan can go into the oven when necessary.
- Toaster – Everyone surely has a toaster? Well if you don’t, this is my recommendation, click the link to check it out!

Serving suggestions for mushrooms on toast with poached egg

Storage and freezing
This dish is best eaten fresh, but if you've made extra (or accidentally cooked enough mushrooms for a small army), here's how to keep it tasting great.
- Fridge: Store the cooked mushrooms in an airtight container for up to 3 days.
- Reheat: Reheat the mushrooms gently in a pan with a tiny splash of water or butter to bring back the juiciness.
- Let the mushrooms get properly golden – Don't rush them - colour equals flavour. Give them space in the pan and let them sizzle until they look irresistible.
- Use good chunky bread and toast it well – This dish is all about textures. A sturdy, well‑toasted slice makes every bite better.
- Balance the umami with something fresh – A handful of watercress or lamb's lettuce cuts through the richness and makes the whole plate feel brighter.
- Season as you go – Mushrooms love salt. A pinch at the start and a pinch at the end makes a huge difference.
- Don't overthink the egg – Poached, fried, soft‑boiled - whatever gets you that runny yolk is the right choice.
- Finish with herbs – Chives add a clean, fresh pop that lifts the whole dish. It's a tiny step that makes it feel restaurant‑level.
FAQ
Can I use any type of mushrooms?
Pretty much any mushrooms work. Chestnut, button, portobello, or a mix all taste great. Use whatever you've got in the fridge.
Do I have to poach the egg?
Nope. A fried or soft‑boiled egg works just as well. The goal is that runny yolk.
Is this recipe vegetarian?
Yes, as long as you use a vegetarian Worcestershire sauce (or swap it for balsamic).
Does it work without soy sauce or Worcestershire?
It does, but you'll lose some of that deep umami flavour. A splash of balsamic or tamari can help fill the gap
Are mushrooms and egg on toast healthy?
Yes – it's a naturally balanced meal with protein from the egg, fibre from the mushrooms and carbs from the toast. Use wholemeal bread for extra fibre, and cook the mushrooms in a little olive oil for a healthier twist.
Can I make it dairy‑free?
Absolutely. Use olive oil instead of butter and skip any optional cheese.
How to cook mushrooms for mushrooms on toast?
Cook them over a medium‑high heat with a little oil or butter, giving them space in the pan so they can brown instead of steam. Let the moisture cook off, then add garlic, herbs or seasoning for extra flavour
What goes well with mushrooms on toast?
A perfectly poached egg is the classic pairing, but it also goes well with wilted greens, crispy bacon, roasted tomatoes or a sprinkle of Parmesan. A side salad or fresh fruit works nicely if you want something lighter.

Umami cowboy mushrooms, toast and poached egg
Equipment
Ingredients
- 130 grams mushrooms
- 1 teaspoon butter
- 1 clove Garlic
- 1 tablespoon Worcestershire sauce
- 1 tablespoon soy sauce
- 1 egg
- 1 slice bread
- 1 handfull chives
- salt and pepper
- 1 handfull lambs lettuce or watercress
Instructions
- Cut the mushrooms in half or quarters, this recipe is best with chunky mushrooms. Dice the garlic. Put a pan of salted water on the hob ready for the poached egg.
- Melt a generous knob of butter in a frying pan over medium heat. Add the diced garlic to the butter and Sautee for a minute. Add the mushrooms and cook until they start to soften and release their juices.

- Spoon the cowboy mushrooms generously over the buttered toast, Top with the poached egg. Finish with diced chives for freshness and colour. Serve with some lambs lettuce or watercress…….delicious!
Notes
- Mushrooms love space - crowd the pan and they'll steam instead of brown. Give them room and they'll go golden, glossy, and full of that cowboy umami magic.
- Butter first, flavour second - starting with butter gives you richness, and adding garlic, soy, and Worcestershire builds that deep savoury hit that makes these mushrooms taste like they've been on a campfire (minus the actual camping).
- Soy + Worcestershire = instant umami - it's the quickest way to turn everyday mushrooms into something you'd happily serve at brunch without apologising for "just mushrooms on toast."
- Poach the egg gently - a soft, runny yolk is the sauce for the whole dish. Think gentle simmer, not a rolling boil that bullies the egg into submission.
- Toast matters - go for something sturdy that can handle juicy mushrooms and a wobbly egg. This is not the moment for flimsy bread that collapses under pressure.
- Chives are more than decoration - they add a fresh, sharp lift that cuts through the richness. Plus, they make the plate look like you tried.
- Serve immediately - cowboy mushrooms wait for no one. Assemble, top with the egg, sprinkle the chives, and get stuck in while everything is hot and happy.
