It has been a busy couple of months. I’m getting used to the lack of cooking companion in my doorway, watching intently as food moves from countertop to stove (and sometimes to the floor – much consternation resulted!), and I’m slowly regaining that urge to putter around and experiment in the kitchen. I didn’t know how much this part of my life would be impacted by the absence of a big, golden dog.
But anyway, in addition to that change, we’ve also been busy planning our summer (more on that soon…), and working through the semester, and at the end of April, N. crossed a huge item off his bucket list as he successfully finished the Eugene Marathon! Not only was this a major accomplishment for him; it also provided the inspiration for this post. During that weekend, we stayed with our friends S. and M., and as part of a Friday evening happy hour spread, S. made these mushroom caps, smeared with a mixture of miso paste and butter, broiled until charcoal black but so savory and deep and perfect we could barely keep our fingers away long enough to let them cool. They were a restaurant recreation of hers, from an appetizer at a local izakaya, and I haven’t stopped thinking about them since. On a long, slow Saturday, punctuated by errands and an intense summer travel planning session, they seemed the right late-afternoon accompaniment to a glass of pinot noir.
The ingredient list here is unusually short, for me: shiitake mushrooms, miso, butter. Maybe a shower of chives, if you want a little color and hint of onion-y freshness on top. The mushrooms are stemmed, the miso and butter are whisked or smeared or stirred together, the mixture gets liberally frosted onto the gills of the shiitakes, and into the broiler they go. 5-10 minutes later, you are dispensing small, homely saucers approximately the temperature of the molten center of the earth, but so incredibly savory and chewy and crusty and almost too salty in just the right way, that if you are anything like me, you will already have eaten a few in the kitchen before anyone else knew they were ready.
When you broil miso and butter together, some of the intense mixture seeps down into the mushroom as it softens and barely cooks through, but much of it remains trapped in the enclosing folds of the cap, where the butter bubbles and the miso takes on an appealing char not unlike the crusty exterior of a grilled steak.
The trickiest part of the whole procedure is managing your broiler. You want the mushrooms to cook, but you also want the deep browning on top, and since every broiler is so different, I’ve included below only the most basic of instructions. Yours might do best on low, or on high, and it might take as few as four or as many as ten minutes for satisfactory results. In any case, I’d say to let them go a tiny bit longer than you think you need to, because I promise it isn’t burning; it’s just getting better.
Miso Butter Broiled Shiitakes
10-15 minutes, depending on your broiler
For 8 shiitake caps:
8 large shiitake mushrooms, stems removed
2 tablespoons red miso paste (or use white for a less intense miso flavor)
4-5 tablespoons softened (not melted) unsalted butter
sprinkle of chives to garnish, optional
- Preheat your broiler. I set mine to low with the rack closest to the broiler element. Broilers are all so different, so you might need to experiment a bit.
- In a small bowl, combine the miso paste and softened butter with a flexible rubber spatula. Mix and smash and stir until the butter and miso are homogenized.
- Using the same spatula, fill each cap with the miso and butter mixture. Depending on the shape of your shiitakes, you might have more or less room to fill. Mine were quite roomy and I used almost all of the mixture. If yours are small or flattish, you will probably have miso butter left over. May I suggest an amazing spread for avocado toast?
- Arrange the filled mushroom caps evenly, with space in between, on a broiler-safe tray or pan. Broil until the miso and butter mixture is bubbly and very, very dark – it will look a little burned – and the mushroom caps have softened and flattened a bit. Again, broilers are so different. On low, mine took about 7 minutes. Play with yours and judge accordingly.
- Remove from the oven and let sit 1-2 minutes, until they are no longer the temperature of fresh lava. Sprinkle with chives if desired, scoop onto a decorative plate, and consume immediately.
