Ingredients for this Garlic Mushroom Grilled Cheese
- 1 tablespoon olive oil
- 1 tablespoon butter (plus more for toasting bread)
- 2 cups cremini or button mushrooms, sliced
- 2 garlic cloves, minced
- ¼ teaspoon salt
- ¼ teaspoon black pepper
- 1 teaspoon chopped thyme (optional)
- 4 slices of sourdough bread
- 1 cup shredded mozzarella (or slices)
- Optional: Swiss, provolone, or fontina cheese for blending

Step 1: Sauté the Mushrooms
In a skillet over medium heat, add olive oil and butter. Once melted, toss in the sliced mushrooms. Let them cook undisturbed for 3-4 minutes to develop color, then stir and continue to cook for another 5-6 minutes until golden brown.
Step 2: Add Garlic and Seasoning
Stir in the minced garlic, salt, black pepper, and thyme (if using). Cook for another 1-2 minutes until the garlic is fragrant but not burnt. Remove from heat and set aside.
Step 3: Assemble the Sandwiches
Butter one side of each bread slice. Place the unbuttered side down and layer with half of the cheese, followed by the garlic mushrooms, then top with the remaining cheese and a second slice of bread (buttered side up).
Step 4: Grill to Golden Perfection
Heat a non-stick pan or griddle over medium-low heat. Place the sandwiches and cook for 3-4 minutes per side until the bread is golden and the cheese is melted. Press gently with a spatula for even grilling.
Step 5: Serve and Enjoy
Let rest for 1 minute before slicing. Serve hot with a sprinkle of parsley or your favorite dipping sauce.
Frequently Asked Questions
Can I use different mushrooms?
Absolutely. Feel free to swap in shiitake, oyster, or portobello mushrooms for a deeper or more delicate flavor profile.
What cheese works best besides mozzarella?
Provolone, Swiss, fontina, or even brie pair beautifully with garlic mushrooms.
Can I make it vegan?
Yes! Use vegan butter and a plant-based cheese that melts well. Also double-check that your bread is dairy-free.
How do I keep the sandwich from getting soggy?
Make sure the mushrooms are well-cooked and not watery before adding them to the sandwich. Toasting the bread until golden also helps seal everything.
What bread should I use?
Sourdough is ideal for flavor and structure, but any hearty artisan bread or thick-sliced sandwich loaf works.
Can I add anything else?
Yes—try a handful of spinach, caramelized onions, or a swipe of Dijon mustard for extra depth.
