Ingredients
- 24 medium cremini mushrooms (about 1 1/2 pounds), stems removed and finely chopped
- 1 tablespoon olive oil, plus 1 teaspoon for the topping
- 3 cloves garlic, minced
- 4 cups baby spinach, roughly chopped (about 4 ounces)
- 3/4 cup plain nonfat Greek yogurt, drained 15 minutes if it looks wet
- 1/2 cup finely grated Parmesan cheese, divided
- 1/2 cup whole wheat panko breadcrumbs, divided
- 1/4 cup finely chopped fresh parsley, plus more for serving
- 1 teaspoon fresh thyme leaves
- Finely grated zest of 1 lemon
- 1/2 teaspoon fine sea salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon smoked paprika
Instructions
- Heat the oven to 400 degrees F. Line a rimmed sheet pan with parchment paper. Wipe the mushrooms clean with a damp cloth, twist out the stems and chop the stems fine.
- Arrange the caps hollow side up on the pan, brush very lightly with olive oil, and bake empty for 8 minutes, until they release their liquid. Pour the liquid off and pat the caps dry.
- Heat the tablespoon of olive oil in a large skillet over medium heat. Cook the chopped stems 5 to 6 minutes, until their liquid has cooked away and the edges turn golden.
- Add the garlic and cook 30 seconds. Add the spinach and cook 2 to 3 minutes, until wilted and the pan looks dry. Cool 5 minutes and press out any last moisture.
- Stir together the Greek yogurt, half the Parmesan, half the panko, the parsley, thyme, lemon zest, salt, pepper and smoked paprika. Fold in the cooled stem and spinach mixture.
- Fill each cap generously, mounding slightly. Toss the remaining panko and Parmesan with the teaspoon of olive oil and sprinkle over the tops.
- Bake 12 to 14 minutes, until the caps are tender and the topping is deep golden. Rest 5 minutes, scatter with extra parsley, and serve warm.
Notes
Make ahead: pre-bake the caps, fill them, cover and refrigerate up to 24 hours; add the panko topping just before baking and bake 14 to 16 minutes from cold. Leftovers keep 3 days in the refrigerator and reheat best in a 375 degree F oven for 8 minutes so the tops crisp again; the microwave softens them. For a dairy free version, use a thick plain almond or coconut yogurt, swap the Parmesan for 2 tablespoons of nutritional yeast plus an extra pinch of salt, and mound the filling modestly.
