These tuna stuffed mushrooms are an easy option to serve as an appetizer or as a side dish for any meal. I make them with XL mushrooms so there's plenty of room for the filling, along with eggs, tuna in olive oil, and lactose-free shredded cheese. A bit of onion powder and oregano brings plenty of flavor without complicating the ingredient list.
If you're looking for baked tuna and cheese stuffed mushrooms, this recipe takes just 15 minutes of prep and 30 minutes in the oven. The egg helps bind the filling together, while the cheese melts into a lovely golden crust. I love this combination to share at the table: it makes 10 large mushrooms, perfect for 4 people.
For a different filling, I recommend these tuna and spinach stuffed mushrooms; if you'd like another way to cook them, try these microwave tuna stuffed mushrooms.
