About this dish
Whole portobello caps braised low and slow in a deeply reduced Burgundy-style sauce — the secret is searing the mushrooms hard before braising so they develop a mahogany crust rather than steaming into softness.

Method
Dice the onion, carrots, and celery. Slice the garlic. Remove the portobello stems and wipe the caps clean with a damp cloth. Season both sides of each cap generously with salt and pepper.
Heat the olive oil in a wide, heavy-bottomed braising pan or Dutch oven over high heat until shimmering and just beginning to smoke. Place the mushroom caps gill-side up and sear for 3-4 minutes without moving, until the underside is deep brown and caramelised.
Flip the caps and sear the gill side for 2-3 minutes until golden. Transfer the caps to a plate and reduce the heat to medium.
Add the 2 tbsp butter to the same pan. Once foaming, add the onion, carrot, and celery with a pinch of salt and cook for 8-10 minutes, stirring occasionally, until softened and lightly golden.
Add the garlic and tomato paste, stirring constantly for 2 minutes until the paste darkens by a shade and smells sweet and toasty.
Pour in the red wine, scraping up any browned bits from the base of the pan. Increase the heat to high and reduce for 8-10 minutes until the wine is reduced by half and no longer smells of raw alcohol.
Add the vegetable stock, soy sauce, thyme, rosemary, bay leaf, and crushed peppercorns. Stir to combine, then nestle the portobello caps gill-side up into the braising liquid — they should be partially submerged.
Reduce the heat to low, cover with a lid slightly ajar, and braise for 25 minutes until the caps are completely tender and the sauce has thickened to a glossy, coating consistency.
Transfer the mushrooms carefully to a warm serving dish. Discard the thyme, rosemary, and bay leaf. Whisk the Dijon mustard and cold cubed butter into the sauce over low heat for 1-2 minutes until emulsified and silky.
Spoon the sauce generously over the portobello caps, finish with flaky sea salt, and scatter with fresh parsley. Serve immediately.
