FAQs
Can I prepare the stuffed mushrooms in advance?
Yes, you can prepare and stuff the mushrooms ahead of time, then cover and refrigerate them before baking. Bake just before serving for best results.
Can I use other types of mushrooms for this recipe?
While portobello mushrooms work best due to their size and meaty texture, you can use large cremini or white mushrooms, but the baking time may be shorter and the filling quantity may need adjusting.
