Fire-Roasted King Oyster Mushroom Steaks with Sizzling Walnut-Aleppo Crunch
Welcome to my kitchen! Growing up in Tel Aviv, we lived for the grill, but moving to London taught me how to coax deep, smoky magic out of unexpected ingredients. That is how these Fire-Roasted King Oyster Mushroom Steaks were born. I remember the first time I served these at a backyard supper in Hackney; my most devoted carnivore friends went completely quiet, knife and fork poised, mesmerized by the meaty texture and charred pomegranate glaze. What makes this recipe so special to me is how it redefines what a vegetable-forward main can be. We are roasting those thick stems until they are meltingly tender inside, then layering them over a velvet-smooth garlic-lemon tahini that I truly believe belongs on everything. The real magic, though, is the contrast. You get the crunch of sizzling walnuts kissed with Aleppo pepper, the bright punch of a fresh herb tatbilah, and the jewel-like pop of pomegranate seeds. If you cannot find king oysters, thick slices of portobello will do, but promise me you will not skimp on the herbs. More is always the answer! Pour yourself a glass of wine, fire up the grill, and let us make something vibrant.

- 1.5 tsp kosher salt(divided)
- 0.5 cup raw sesame tahini(well-stirred, preferably Ethiopian or Lebanese)
- 0.25 cup fresh lemon juice(divided (about 4 tbsp total))
- 0.33 cup ice-cold water(as needed for emulsifying tahini)
- 0.33 cup walnuts(coarsely chopped)
- 1.5 tsp Aleppo pepper flakes(or silk chili flakes)
- 1 tsp nigella seeds
- 1 small serrano pepper(finely minced with seeds)

- 0.25 cup fresh dill(roughly chopped)
- 0.25 cup fresh mint leaves(torn)
- 0.25 cup fresh flat-leaf parsley leaves(roughly chopped)
Instructions
- 1
Build a medium-high charcoal fire or preheat an open-fire grill grate to medium-high heat (around 425°F to 450°F / 220°C).
10 min
Tip: If cooking indoors, preheat a heavy cast-iron ridged grill pan until smoking hot.
- 2
Slice 1.25 lbs king oyster mushrooms in half lengthwise. Using a sharp paring knife, score the cut sides in a tight diamond crosshatch pattern about 1/4-inch deep, taking care not to slice entirely through.
6 min
Tip: Scoring allows the fire to penetrate deep into the fibers and holds all that savory glaze.
- 3
In a small bowl, whisk together 2 tbsp pomegranate molasses, 1 tbsp extra-virgin olive oil, 1 clove garlic, 1 tsp ground cumin, 0.5 tsp ground coriander, and 0.5 tsp kosher salt. Brush the glaze generously all over the scored mushroom halves, working it deep into the cuts.
4 min
Tip: Let them sit for at least 5 minutes so the salt begins drawing moisture while seasoning the flesh.
- 4
Make the velvet tahini: In a mixing bowl, combine 0.5 cup raw sesame tahini, 3 tbsp fresh lemon juice, 2 cloves garlic, and 0.5 tsp kosher salt. Whisk vigorously—it will seize and turn pasty. Slowly drizzle in 0.33 cup ice-cold water while continuously whisking until the sauce transforms into a pale, silky, billowy cream. Taste and adjust seasoning with extra lemon or salt if desired.
5 min
Tip: Ice-cold water is the magic trick to whipping tahini into an airy, cloud-like consistency.
- 5
Make the tatbilah dressing: In a small bowl, stir together 1 small serrano pepper, 1 tbsp pomegranate molasses, 1 tbsp fresh lemon juice, 1 tbsp extra-virgin olive oil, and 0.25 tsp kosher salt. Set aside.
4 min
Tip: Tatbilah is a classic Levantine hot-pepper condiment that cuts right through rich tahini.
- 6
Lightly oil the grill grates with 1 tbsp extra-virgin olive oil. Place the mushrooms scored-side down directly over the live fire coals. Grill uncovered for 5 to 6 minutes until deeply charred and caramelized with crisp grill edges. Flip and cook on the rounded side for another 4 to 5 minutes, brushing with any remaining pomegranate glaze from the bowl, until tender all the way through.
10 min
Tip: Do not move them for the first 4 minutes; you want a deeply caramelized crust that mimics seared steak.
- 7
While the mushrooms finish roasting, make the crunch: In a small saucepan or skillet over medium heat, warm 2 tbsp extra-virgin olive oil. Add 0.33 cup walnuts, 1 tsp nigella seeds, and 1.5 tsp Aleppo pepper flakes with 0.25 tsp kosher salt. Cook, swirling frequently, for 2 to 3 minutes until the walnuts are golden brown, fragrant, and sizzling in the vibrant red oil.
4 min
Tip: Pull the skillet off the heat the second the nuts are golden so the Aleppo pepper doesn't burn.
- 8
To assemble, spread the whipped velvet lemon tahini across a wide serving platter with the back of a large spoon. Arrange the hot, smoky king oyster mushrooms directly over the tahini. Spoon the sizzling walnut-Aleppo crunch and its fragrant chili oil over the tops. Spoon over the pomegranate-serrano tatbilah, then shower generously with 0.33 cup fresh pomegranate arils, 0.25 cup fresh dill, 0.25 cup fresh mint leaves, and 0.25 cup fresh flat-leaf parsley leaves. Serve immediately with warm flatbread.
4 min
Tip: Layering the sizzling hot oil directly onto the cold tahini creates an intoxicating temperature and texture contrast.
Chef's Notes
King oyster mushrooms have an astonishing, meaty texture that begs for the drama of live fire. Scoring them allows the pomegranate molasses glaze to soak in and caramelize into sticky, charred ridges. When you pair that savory, smoky mushroom steak with an ice-cold swoosh of velvet tahini and a hot, sizzling walnut crunch, you have everything I adore on one mezze platter: bold acid, rich nuttiness, deep heat, and a storm of fresh green herbs.

Born in Tel Aviv to a Moroccan mother and Iraqi father, I grew up speaking the language of spice. My kitchen was always full of cumin, preserved lemons, and the sound of multiple conversations happening at once. I moved to London at 22, cooked my way through the city's best restaurants, and discovered that the whole Mediterranean was my playground. Now I create dishes that celebrate the entire region—from Marrakech to Athens, with plenty of stops in between.
