Ingredients You’ll Need
The magic of this Garlic Mushroom Grilled Cheese Recipe lies in a handful of simple, high-quality ingredients. Each component plays a starring role, from the sharp cheddar’s creamy melt to the golden sautéed mushrooms that add a satisfying bite and deep flavor.
- Sourdough bread: The sturdy crust and tangy crumb hold all the fillings perfectly while crisping to golden perfection.
- Fresh mushrooms (button or cremini): These bring earthiness and a soft, juicy texture when sautéed.
- 2 cloves garlic, minced: Fresh garlic infuses the mushrooms with bold, irresistible aroma.
- 1 tablespoon unsalted butter (plus extra for grilling): Butter adds richness and a crispy, golden crust when grilling the sandwich.
- Sharp cheddar cheese: Sharpness and meltability marry beautifully to make each bite gooey and flavorful.
- Fresh thyme (optional): A sprinkle of thyme adds subtle herbal notes, elevating the mushrooms even further.
How to Make Garlic Mushroom Grilled Cheese Recipe
Step 1: Prepare the Ingredients
Start by giving your mushrooms a rough chop so they’ll cook evenly and maintain texture. Then mince two cloves of garlic finely—that way they’ll blend into the mushrooms smoothly, spreading that wonderful garlicky essence throughout the sandwich.
Step 2: Cook the Mushrooms
Heat one tablespoon of unsalted butter in a skillet over medium heat, then add the chopped mushrooms. Let them sauté gently for 5 to 7 minutes until they soften and turn a gorgeous golden brown, releasing their natural umami flavors. This step is where your sandwich’s soul truly begins to form.
Step 3: Add Garlic and Thyme
Stir in the minced garlic and fresh thyme if you’re using it, cooking everything together for just about a minute. This brief cook time lets the garlic become fragrant and mellow rather than overpowering, perfectly complementing the earthiness of the mushrooms.
Step 4: Assemble the Sandwich
Lay out two slices of sourdough bread and pile on the savory mushroom mixture, then top it with a generous amount of sharp cheddar cheese. The combination of melty cheese and robust mushrooms is incredibly satisfying and makes the sandwich beautifully gooey once grilled.
Step 5: Grill the Sandwich
Now it’s time to get that glorious crust. Heat a skillet over medium-low heat and melt a bit of butter. Place your sandwich in the pan and grill for 3 to 4 minutes on each side until the bread is golden brown and crisp, and the cheese inside is melted to perfection. Patience here rewards you with that crave-worthy grilled cheese crunch.
Step 6: Serve and Enjoy
Once your Garlic Mushroom Grilled Cheese Recipe is grilled to perfection, let it cool for a minute before slicing. This little rest helps the cheese set just enough to keep it from oozing too wildly but keeps everything warm and gooey inside when you dig in.
How to Serve Garlic Mushroom Grilled Cheese Recipe

Garnishes
To finish off your sandwich presentation beautifully, sprinkle a tiny pinch of flaky sea salt or some fresh chopped parsley. These small touches brighten up the flavors and add a bit of color that makes your grilled cheese even more inviting.
Side Dishes
This hearty sandwich pairs wonderfully with light, fresh sides like a crisp garden salad or some tangy pickles to cut through the richness. Tomato soup is a classic and cherished companion for grilled cheese, turning your meal into a comforting feast.
Creative Ways to Present
Feeling playful? Cut your grilled cheese into small, bite-sized triangles perfect for sharing at a casual gathering. Or try rolling it into pinwheels by removing the crust and slicing it thinly, making an elegant party snack with all that garlicky mushroom goodness inside.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers, wrap them tightly in plastic wrap or place them in an airtight container. Stored in the refrigerator, your Garlic Mushroom Grilled Cheese Recipe will stay delicious for up to 2 days—just keep in mind the bread might soften slightly as it rests.
Freezing
You can freeze the sandwiches before grilling to enjoy another day. Wrap each sandwich well in foil and place it in a freezer-safe bag. When you’re ready, reheat from frozen either in a skillet or oven until fully warmed through and crispy on the outside.
Reheating
For the freshest taste, reheat your sandwich in a skillet over medium heat with a little butter. This method revives that delightful crunch and melts the cheese again beautifully. You can also use a toaster oven or conventional oven, but avoid microwaving to prevent soggy bread.
FAQs
Can I use other types of cheese in this Garlic Mushroom Grilled Cheese Recipe?
Absolutely! While sharp cheddar is fantastic for its melt and flavor, you can experiment with gouda, gruyere, or mozzarella depending on your taste preferences. Each cheese will bring its own unique twist to the sandwich.
Are there mushroom varieties that work better than others?
Button and cremini mushrooms are ideal for this recipe because they sauté nicely and absorb the garlic flavor well. You could also try shiitake or portobello for a richer, meatier texture if you’re feeling adventurous.
Can I make this recipe vegan?
Definitely! Substitute the butter with vegan buttery spread, use plant-based cheese that melts well, and ensure your bread doesn’t contain dairy. The mushrooms and garlic flavors stay just as delicious in a vegan version.
How do I prevent the sandwich from getting soggy?
Using sourdough with a sturdy crust helps keep moisture at bay. Also, grilling over medium-low heat ensures the bread crisps up without burning. Avoid adding extra wet ingredients that could contribute to sogginess.
Can I prepare the mushroom filling in advance?
Yes, you can make the sautéed mushroom and garlic mixture ahead of time and store it in the fridge for up to 2 days. Just reheat slightly before assembling your sandwich to maintain the best flavor and texture.
