Ingredients
Alright, let’s make our shopping list! To make this recipe, you will need…
Bread: Use your favourite bread. Today, I have multigrain.
Mushrooms: Shiitake, cremini, oyster, or any mix you love
Miso paste: White miso for a mild, savoury base
Scallions: Fresh, thinly sliced for a burst of freshness
Cheese: I have smoked Gouda in my fridge today. Use any kind of cheese.
Sesame oil, soy sauce, garlic, ginger (optional): For extra flavor depth
Salted butter or oil: For grilling the sandwich to golden perfection

How to Make Miso Mushroom Grilled Cheese Sandwich
Let’s make this dish!
Sauté the mushrooms: Heat neutral oil in a pan over medium heat. Add mushrooms and cook until they release moisture and begin to brown (about 5–7 mins). Stir in miso paste. Add green onions, salt and pepper to taste. Mix until the mushrooms are evenly coated in a glossy glaze. Remove from heat and set aside.

Assemble sandwiches: Lay out your bread. On one side of each slice, lightly butter or oil for grilling. On the inside, layer cheese, miso mushrooms, and another layer of cheese if you like it extra gooey.
Grill: Heat a nonstick pan or griddle over low to medium. Place the sandwich butter-side down and press lightly. Cover pan with a lid and grill for 3–4 minutes per side, until golden brown and cheese is melted. Repeat for the other sandwich.
Serve hot: Slice diagonally, serve, and enjoy that cheesy umami magic!
Miso Mushroom Grilled Cheese Sandwich Options and Substitutions
Want to mix things up with this recipe?
- No scallions? Try thinly sliced leeks, chives, or red onion.
- Want to add more flavour? Add garlic and ginger. Use soy sauce instead of salt. Sprinkle some toasted sesame seeds. Drizzle some sesame oil.
- Want a spicier kick? Add a drizzle of sriracha or gochujang-mayo inside. Sprinkle some chili flakes.
- No white miso? Yellow or red miso also works — it’s just slightly stronger in flavour.
Storage and Reheating Tips
This sandwich is best enjoyed fresh, but if you have leftovers:
Reheating: Reheat on a skillet, in a toaster oven or air fryer for crispness; avoid microwaving, which makes it soggy.
Storage: Wrap in foil or store in an airtight container in the fridge for up to 2 days.
Make Ahead Options
Prep the miso mushrooms up to 2 days ahead and store them in the fridge.
Assemble and grill later when you’re ready to eat — ideal for quick weekday lunches. Be sure to drain all mushroom juices if you are doing this so that the bread does not get soggy.

Recipe Tips
Grill over medium to low heat. You don’t want the sandwich to burn before the cheese melts.
Use a lid while grilling to help the cheese melt faster.
Grated cheese will melt faster than sliced cheese.
Press the sandwich lightly with a spatula to get that crispy, golden crust.
Use a neutral oil if you don’t want to use butter.
