Ingredients You’ll Need

Portobello mushrooms –  You need some biggies for this recipe as you’re going to need to bake an egg in them.  However, you could also produce the same effect by adding some sliced, smaller mushrooms into the bottom of a buttered ramekin if you struggle to find them.

Prosciutto – Good quality, part smoked, part salty, and delicious!  You could also use a good quality nitrate-free deli ham here.

Eggs – Organic and free-range are the best.  You will find the nutrition better and the egg yolk gloriously golden! If you have some extra big mushroom, how about a duck egg for a change?

Parsley – Freshly chopped is best, where the flavor will be far stronger.  You could use a dried mixed herb here instead.

Black pepper – Freshly ground for the deepest taste.

How to Make Mushroom Egg Cups


Preheat the oven to 375F.

First, you need to clean your mushrooms.  Use a damp cloth for this, and don’t put them under a running tap.  You don’t want your mushrooms getting too much moisture as it dilutes their flavor, and they won’t cook quite as well.

Cut off the stems and scrape out the gills to make some space for your egg.

Next, grease a baking tray with olive oil, or you could use baking parchment or liner.

Place the mushrooms, top side down, onto the baking tray and brush them a little with the oil too.  Try this pastry brush, as it makes the job much easier!

Place one slice of the prosciutto into the mushroom, packing it in tidily.

Next, carefully break an egg into each.  You don’t want to break the yolk, so try and keep the egg whole.

Sprinkle over the black pepper and parsley.

Bake in the oven for 25-30 minutes, or until the egg is cooked to your liking and the mushroom is soft.

Cool a little before serving. See below for some additions you could make to your Mushroom Egg Cups!

How Long Do Egg Cups Last in Fridge?

These Mushroom Eggs Cups will last in the fridge for 1-2 days.  They are better eaten fresh from the oven to get the oozing egg and soft mushroom, but you could eat them heated up or even cold if you wish.

If you wanted to save some time, prepare the mushrooms up to 24 hours ahead.  Leave them in the fridge until you’re ready to crack the eggs in.  You can pop them in the oven super quick then, which is great if you are entertaining guests over a brunch or lunch.

You could also serve other ingredients with the Mushroom Egg Cups, which you could prepare ahead of time too.

Other Ingredients You Can Add to This Breakfast

You could make these Mushroom Egg Cups into a bigger breakfast but adding extras.  How about these options? –

Add a simple side of steamed spinach.

Sprinkle over some mixed seeds for some crunch.

Roast some tomatoes on the vine on the same baking tray (adding halfway through the cooking time and don’t forget to drizzle them with olive oil!), serve with the mushrooms.

Add a side of whole-grain toast if you want something a little more filling.

You could use good quality pre-cooked slices of sausages to your mushrooms instead of the prosciutto.

This Mushroom Egg Cup could be served next to a small piece of poached fish of your choice.  A smoked variety is hard to beat here!

Add some fresh avocado and arugula for a tasty added combination.

Like spice? You could serve a spicy tomato salsa on the side.  Or, you could add some fresh, diced red chili to the eggs before baking.

If you like cheese for breakfast, you could top the egg with some grated cheese of your choice.

How about something very different?  Remove the mushrooms altogether and use half a bell pepper, de-seeded and scooped out, baking the egg in there instead.

And don’t forget a drink!  A strong coffee or smoothie would be a perfect addition to these Mushroom Egg Cups.
