Give me your best Portobello Mushroom recipes

Giant portobellos were on sale, so I got a bunch. Besides marinating and grilling as burgers, what other recipes are out there?

Do caprese-stuffed portabellos:
Remove the stems, wash the caps and thoroughly dry them with kitchen paper. Brush the caps with melted garlic butter and lay buttered-side down in a baking dish. Brush the inside of the caps with more garlic butter, and fill with a mixture of the chopped stems, chopped tomatoes (I use rosa/grape or some mix of heirloom varieties) and torn bocconcini or other mozzarella and season with a little salt and pepper. Enough to mound up a little. Grill for around 8 minutes, or until the cheese is quite melted. Add chopped basil and drizzle with a baslamic reduction (I make mine with balsamic and a little smoked sugar, reduced to a thick syrup, but I’m sure you can buy a decent one)

You could also do a preliminary grill of the cap tops before stuffing, if you’re iffy about raw mushroom at all.

Thank you, MrDibble!! That was delish!!

Happy to help!
