The Best Stuffed Portobello Mushrooms (Baked Recipe)
This portobello mushroom recipe is stuffed with cheese, garlic, tomatoes, spinach and bell peppers! Make these cheesy mushrooms for a hearty vegetarian main dish.
My husband grew up eating grilled portobello caps, and they’re truly one of his favorite foods! I was inspired to develop this stuffed portobello mushrooms recipe when we had an overabundance of mushrooms from our farm share. Even if you aren’t a fan of mushrooms, I think you’ll like these easy stuffed mushrooms! The creamy, cheese filing is packed with flavor and vegetables.
This easy recipe makes a great appetizer, side dish or main course! Stuffed portobellos have a meaty texture and can truly be a whole meal by themselves if that’s what you’re looking for!
Choosing the Right Mushroom:
When picking out your portobello mushroom caps, look for mushrooms that are 4-6 inches around and firm to the touch. To clean the mushrooms, wipe them clean with a damp cloth. I don’t recommend rinsing them in water because they tend to take on water and get a little waterlogged, which could result in them being a bit soggy when cooked.
Make Ahead Instructions:
This great recipe can be made ahead of time! Go ahead and stuff your mushrooms, then tightly wrap them in plastic wrap. Store them in the refrigerator for up to a day before cooking! You will want to bring them out of the fridge 20-30 minutes before they go in the oven to allow them to sit at room temperature and take the chill off of the creamy filling!

Substitutions and Additions:
This stuffed mushroom recipe is super versatile. Here are a few suggestions for recipe substitutions or additions:
- Instead of the cream cheese, feel free to use goat cheese or feta cheese

- You can also add 3/4 cup crab meat, Italian sausage, ground beef, ground turkey or any cooked sausage to the stuffing mixture for extra protein
- After baking, drizzle with balsamic glaze for extra flavor.
- Instead of the red peppers, use green or yellow bell peppers.
- Substitute cheddar cheese for the mozzarella cheese
- Caramelized onions are a wonderful addition to the filling or the topping!
- Add a handful of diced green onions to the filling.
- Adapt this recipe by using smaller mushrooms, removing the stems and stuffing. You will need 1-1.5 pounds of mushrooms.

- Use a spoon to fill the mushroom caps with the mixture from the skillet.
