👪 FAQs
Yes, the gills are completely edible! In some cases recipes will instruct you to remove them, but this is typically for visual reasons. These mushrooms are covered up with delicious tomato and gooey cheese anyway, so it doesn't make a difference!
Take something like tongs or a fork and press gently in the center (where you removed the stem). The mushroom should be tender and juicy.
For the purposes of this recipe, peeling your mushrooms isn't necessary. This typically just gives them a more professional look, but won't affect the flavor or texture much.
A way to easily tell is to feel the surface of the mushroom; a sticky or slimy texture is a sure sign that your mushroom is bad. A darker color can also indicate that your mushrooms are starting to turn.

🧊 Storing Baked Portobello Mushrooms
While these mushrooms are best enjoyed right out of the oven, you can store them in airtight containers or wrapped tightly in plastic for 4-5 days in the refrigerator. To reheat, drizzle with a bit of olive oil and toss them in the oven at around 350 degrees F until the cheese is melted and everything is heated through.
Your leftovers can also be frozen, but be sure to wrap them up well to avoid freezer burn or your ingredients getting dried out. They should last a few months in the freezer, and to reheat them just give them some time to thaw (placing them in the fridge overnight is usually a good amount of time) and bake them as instructed above.
💭 Helpful Tips
- Allow your mushrooms to sit for a few minutes after baking to really settle into their flavor and finish cooking all the way through.
- While mushroom gills are completely edible, leaving them on will result in a slightly earthier flavor overall. Scoop them out with a spoon before baking if you like!
Baked portobello mushrooms with cheese are the perfect low-stress and guilt-free snack or appetizer; they're sure to impress guests or your family every time!
📖 Variations
- For even more cheesiness, try another mild cheese Parmesan or provolone.
- Use salt and pepper, thyme, paprika, chili powder, or any combination of spices and seasonings to make these baked mushrooms your own!
- Drizzling with some balsamic glaze would be another fantastic addition to this recipe.
- To get an even more rich dish, use melted butter instead of olive oil.
- You can also use grape tomatoes cut into thirds if you prefer more bite-size pieces of tomato.

Boy, these portabellas look absolutely delicious! I'm not a big fresh tomato fan, but I bet it might be pretty good with sun dried tomatoes instead. The next time I'm at the super nice gourmet grocery store, I'm picking up the ingredients to make this.
