I love mushrooms for their rich umami flavor and earthy essence. Available year-round at most grocery stores, they’re incredibly versatile and delicious whether grilled, baked, pan-fried, or air-fried and makes a great lent dinner recipe.
The best mushrooms for this sandwich are basic white button mushrooms or brown baby bellas (a more mature form of the white variety). They’re widely available year-round at most grocery stores and are budget-friendly.

Ingredients
Scroll down to the recipe card below for full information on ingredients and amounts.
- Pan Fried Mushrooms - I use my sauteed garlic mushrooms recipe. It is garlicky, buttery, and perfectly seasoned.
- Tomato - Use a well-ripened tomato like Roma, Beef steak, or Heirloom variety for the mushroom sandwich.
- Cheese - When it comes to cheese, anything goes! A good melting cheese like mozzarella is our go-to when it comes to pairing with tomato, but other types like provolone, Mexican blend, Monterey jack, and pepper jack are all great options to try.
- Bread - Any type of white bread like a crusty loaf, sourdough or soft sandwich bread are all great options. Make sure that the slice is thin enough so the filling shines though but also not too thin, that it falls apart. I prefer not to use too dense or sweeter varieties of bread like brioche or challah.
Tip: Try combining different types of cheeses or an interesting twist. For a gourmet touch, try Gruyere - It’s nutty and rich and just salty enough.
Variations
- Use mayonnaise instead of butter. Mayo has a higher smoke point than butter, which means your can cook your mushroom sandwich in a slightly higher heat for a crisper exterior.
- Saute sliced onions along with mushrooms for some sweetness.
- Wilt baby spinach with the filling.

Pro tip: You want to cook the mushroom sandwich in medium heat. It is important to make sure that they don’t get browned too fast before the cheese melts.
Make open-faced mushroom sandwich - To make an open-faced vegetarian sandwich, place a toasted slice of bread on a baking sheet, pile the filling on top, and finish with a generous helping of shredded mozzarella. Bake in a preheated 400-degree oven or air fryer until the mozzarella melts.
How to serve?
This mushroom sandwich is perfect as a filling snack, lunch or light dinner. Here are a few pairing suggestions:
- With Soup - What's better than a grilled cheese and hot soup? Serve with Instant Pot Tomato Soup or Spinach Soup.
- For entertaining - Make a bite-size crostini. Use sliced baguette instead to make open-faced crostini melts.
- For Breakfast - Add a fried egg to make a tasty breakfast mushroom sandwich.
Recipe tips
- Assembly - Begin filling and end again with mozzarella, this helps the filling to stick to melted cheese and stay intact upon cooking.
- Press down - Pressing the mushroom sandwich down with a flat spatula or a heavy flat-bottomed pan will help to crisp up the crust and make the filling adhere well with the melted cheese.
- Heat - High heat will burn the exterior of your mushroom sandwich before your mozzarella gets a chance to melt. Medium heat is the way to go for your mushroom sandwich.

Is it good if added with lettuce?
Maria Doss
Lettuce is usually not a recommended addition with hot cheese sandwiches, since it tends to wilt and losses it's crunch and freshness - Maria
