FAQs

Can I use fresh spinach instead of frozen?

Yes, you can use fresh spinach. Simply sauté it briefly to wilt and remove excess moisture before mixing it into the filling.

What if I don’t have a grill?

You can bake the stuffed mushrooms in a preheated oven at 375°F (190°C) for about 20-25 minutes until tender and heated through.

Instructions

  1. Prepare the Mushroom Caps: Remove the stems and gills from each Portabella mushroom cap using a small spoon or butter knife to create space for stuffing.
  2. Season the Mushrooms: Rub the inside and outside of each mushroom cap with extra virgin olive oil, then sprinkle with salt and pepper evenly to enhance flavor during grilling.
