• to tastesalt and pepper
• about 65 g (2/3 cup)grated Parmesan or Romano, or grated vegan cashew-milk cheese

Instructions

1. 1

   Prepare mushrooms

   If the mushrooms have stems, remove, trim and chop them. Set the caps aside in a lightly oiled baking dish large enough to hold them in one layer. Preheat the oven to 170°C (350°F).

2. 2

   Soften vegetables

   Heat the olive oil in a large frying pan and cook the onion over a medium heat until very soft, about 10 minutes. Add the potato, aubergine and pepper, stirring to coat them in oil. Cover and steam in the oil for about 5 minutes, then stir in the garlic.

3. 3

   Simmer filling

   Add the wine and, once it has cooked off, stir in the tomatoes and balsamic vinegar. Turn up the heat and simmer for about 8 minutes, until the liquid has evaporated. Season with salt and pepper to taste, take the pan off the heat and gently stir in the oregano.

4. 4

   Fill the caps

   Leave the vegetable mixture to cool. Spoon a mound of it into each mushroom cap. Add the grated cheese at this stage if you are using it.

5. 5

   Bake and serve

   Bake for about 20 minutes, until the mushrooms are soft and the vegetables are lightly browned with a few charred edges. Remove from the oven and serve.

What are portobello mushrooms stuffed with briam?

Briam is a Greek vegetable dish, commonly made with a mix of vegetables cooked until tender and richly flavoured. Here, that mixture becomes a filling for large portobello caps, turning a familiar Greek-style vegetable preparation into an oven-baked main.

The mushrooms provide a substantial base, while aubergine, courgette, potato, pepper and tomato make a soft, savoury filling. Oregano and balsamic vinegar add aromatic and tangy notes.

Nutrition and macros by portion

The nutrition label shows one serving as written: 250 calories, 7g protein, 19g carbs, 17g fat.

The potato and vegetables supply most of the carbohydrates, while olive oil and optional cheese contribute much of the fat. The mushrooms and cheese provide some protein. Serve with extra greens for a lighter plate, or add bread or a grain if you want a more substantial meal.

Choosing and preparing the mushrooms

Large caps: Choose mushrooms that sit fairly flat and have enough space inside for a mound of filling. The recipe allows either six or eight caps, so the amount in each will vary with their size.

Stems: If present, chop the trimmed stems and set them aside as directed. The method does not specify when to add them, so you can leave them out or stir them into the vegetable pan with the other diced vegetables.

Build the filling in stages

Start gently: Cooking the onion for about 10 minutes softens it before the firmer vegetables go in. Covering the pan for the next 5 minutes helps the potato, aubergine and pepper begin to cook.

Finish with herbs: The wine cooks off before the tomatoes and vinegar are added, and the filling then simmers until its juices have evaporated. Stir in the oregano off the heat to keep its aroma fresh.

Get the filling texture right

Cook off the liquid: The filling should be moist but not watery when it goes into the caps. Simmer it until the juices have cooked away, or excess liquid can collect in the baking dish.

Cool before stuffing: Letting the mixture cool makes it easier to mound into the caps. It also gives you a chance to judge whether the filling is thick enough to stay in place.

Check for doneness

Oven cue: After about 20 minutes at 170°C, the mushroom caps should be soft and the top of the filling lightly browned. A few darker, slightly charred spots are part of the intended finish.

Timing: The caps may vary in size, so start checking near the end of the stated baking time. If they are still firm, give them a little longer and check again.

Cheese and serving ideas

Optional topping: Parmesan or Romano adds a salty, savoury finish; the listed vegan cashew-milk cheese is an alternative. Add it after filling the caps, before they go into the oven.

To serve: Pair the mushrooms with a green salad or steamed greens for a lighter meal. Bread or a simple grain makes the plate more filling and can be useful alongside any juices from the vegetables.

Recipe notes & tips

• Dice the vegetables to a similar size so they cook at a more even rate.
• Drain the tinned tomatoes well to help the filling reduce without becoming watery.
• Use a baking dish that holds the caps in one layer so they cook evenly.
• Taste the filling for salt and pepper before spooning it into the mushrooms.
• Add the cheese before baking if you want it to melt and brown on top.

Variations

• Herb swap: Use dried thyme in place of some or all of the oregano.
• Spicy edge: Add a pinch of chilli flakes to the vegetables with the garlic.
• Cheese-free: Leave off the cheese or use the listed vegan cashew-milk alternative.
• Extra greens: Stir chopped spinach into the hot filling until it wilts.
• More tomato: Add a little extra drained tomato, then simmer until the filling is thick again.

Common mistakes to avoid

• Watery filling: Drain the tomatoes and simmer the mixture until its juices have cooked away.
• Hard potato: Dice it small and give it the full covered steaming time before adding the wine.
• Burnt garlic: Add it after the vegetables have steamed, then stir it in briefly.
• Overfilled caps: Leave the filling in a mound without packing it down too tightly.
• Uneven baking: Arrange the caps in a single layer and use a dish that fits them without crowding.

How to store

Refrigerate leftovers in a covered container for up to 3 days. Reheat in an oven at 180°C until hot throughout; the mushrooms will soften further. You can also microwave individual portions, though the topping will not stay as browned.
