1lbOyster Mushroomspulled into shreds or torn into bite-sized bits. You're welcome to use any combination of white button, cremini, king trumpet, shiitake, or other wild mushrooms you prefer!

Heat 1 tablespoon each of oil and butter over medium heat in the largest sauté pan you have. When the butter is melted and bubbling, add the mushrooms and approximately half the salt. Sauté until slightly wilted and beginning to brown.
Add onions and remaining salt. Continue to sauté, stirring occasionally, until the liquid evaporates, the onions are caramelized, and the mushrooms are getting a lovely golden crust, about 20-25 minutes. There should be some fond sticking to the bottom of the pan.
Deglaze the pan with the white wine, scraping up the browned bits of fond. Continue to cook until the wine is evaporated. Adjust seasoning as needed. Remove the mushroom and onion mix from the pan.
Goat Cheese
While the mushroom and onion mix is cooking, make the herbed goat cheese. Mash together goat cheese, yogurt, and 3 tablespoons of the dill (reserve 1 tablespoon for serving). Season with salt and pepper to taste.
Large-Format Crouton (Optional, see notes)
In the same pan as you cooked the mushrooms (to cut back on dishes), heat the remaining ½ tablespoon of oil and butter over low-medium heat. Pan fry the sliced bread until golden and lightly crisp.
Assemble
Smear the prepared croutons with the goat cheese mixture. Top with the sautéed mushroom and onion mixture. Season with flaky salt to taste. Add a sprinkle of the remaining fresh dill and any other garnishes you desire, then dig in!
Notes
Sautéed Mushroom Mix and Spreadable Goat Cheese can be prepared and stored in the fridge up to 5 days ahead of time.
For a lighter meal, simply toast the bread instead of pan-frying it like a crouton.
Add extra heft and protein with a fried, soft-boiled, or pickled egg.
Pairs well with a glass of dry, mineral-y white wine (e.g. Pinot Grigio, Vinho Verde, Txocolina)
