- 24 oz white mushrooms (diced): The star ingredient offering a meaty texture and earthy flavor.
- 8 oz bacon (chopped into thin strips): Adds a smoky crunch that contrasts beautifully with the mushrooms.
- 2 Tbsp mayonnaise: Creates creaminess and a slight tang to bind the filling together.
- 1/4 to 1/2 tsp salt: Essential for seasoning to taste and balancing all flavors.
- 1/4 tsp black pepper: Adds subtle heat and depth.
- 2 1/2 cups Mexican cheese blend (finely shredded): Melts beautifully, infusing the sandwich with gooey, cheesy goodness.

How to Make Mushroom Sandwich Melts Recipe
Step 1: Sauté the Onions and Garlic
Start by preheating your oven to 350˚F and lining a large baking sheet with parchment paper. Heat 1 tablespoon of butter in a large non-stick skillet over medium heat. Add the diced onions and sauté while stirring frequently until they soften up and turn a lovely golden shade, about 5 to 7 minutes. Then, toss in the pressed garlic and stir for just about a minute until it’s wonderfully fragrant. Transfer this flavorful mixture into a large mixing bowl to prepare for the next steps.
Step 2: Cook the Mushrooms
Using the same skillet, add the remaining 1 tablespoon of butter and crank the heat to medium-high. Add your diced mushrooms and cook them down until they release their liquid and it evaporates completely. This should take about 10 to 12 minutes. You want those mushrooms tender but not soggy, concentrated in flavor and ready to mingle with the other ingredients. Transfer these cooked mushrooms into the mixing bowl with your onions and garlic.
Step 3: Crisp the Bacon
Now it’s time to add some indulgence with the bacon. Keeping the skillet over medium-high heat, add your chopped bacon strips and sauté until they turn crisp and browned, roughly 7 minutes. Once done, place them on a paper towel-lined plate to drain the excess fat. After that, mix the bacon into your growing bowl of savory goodness.
Step 4: Combine the Filling
This is where all the magic comes together. Add the 2 1/2 cups of shredded Mexican cheese blend, 1/4 cup of freshly chopped parsley, and 2 tablespoons of mayonnaise to your mushroom, onion, garlic, and bacon mixture. Season generously with salt (start with 1/4 teaspoon and adjust according to your taste) and a pinch of black pepper. Stir everything until it’s perfectly combined, creamy, and ready to spoon onto your bread.
Step 5: Assemble and Bake
Spoon generous mounds of this cheesy mushroom filling onto your toasted baguette slices. Shape the mixture with your spoon so it sits neatly on each toast. Arrange the prepared toasts on the parchment-lined baking sheet and bake in your preheated oven for about 15 minutes. When the cheese is melted and bubbling, and the edges are golden, garnish with some extra fresh parsley if you wish. Serve your Mushroom Sandwich Melts Recipe warm and watch them disappear fast!
How to Serve Mushroom Sandwich Melts Recipe
Garnishes
A sprinkle of fresh parsley is the classic way to brighten these melts, but you could also try a dash of smoked paprika or finely chopped chives to bring an extra pop of color and flavor. A light drizzle of a good-quality olive oil or a small scatter of red chili flakes can add a nice touch if you want a subtle kick.
Side Dishes
These melts shine on their own but pair beautifully with a crisp green salad lightly tossed in lemon vinaigrette to cut through the richness. Creamy tomato soup or a simple roasted vegetable medley would also complement the earthy mushrooms and melty cheese, making the meal feel extra special and well-rounded.
Creative Ways to Present
Have fun with presentation by serving the mushroom melts as bite-sized appetizers at your next gathering—just slice the baguette smaller. You could also turn this into a layered open-faced sandwich or serve alongside a glass of your favorite fresh white wine or a cold amber ale for a cozy pairing. The versatility makes the Mushroom Sandwich Melts Recipe a crowd-pleaser no matter the occasion.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftovers, store them in an airtight container in the refrigerator. They will keep well for up to 3 days. The flavors deepen with time, so reheated melts taste just as delightful and comforting.
Freezing
To freeze, allow the prepared but unbaked mushroom melts to cool completely, then place them on a baking sheet in a single layer and freeze until solid. Transfer to a freezer-safe container or bag for up to 2 months. When ready to enjoy, bake them straight from frozen, adding a few extra minutes to the baking time.
Reheating
The best way to reheat is in an oven or toaster oven at 350˚F until warmed through and the cheese is melted again, usually about 10 minutes. Avoid the microwave if possible, as it may make the bread soggy and the texture less appealing.
FAQs
Can I use other types of mushrooms for this recipe?
Absolutely! While white mushrooms are suggested, cremini, button, or even a mix of wild mushrooms will work wonderfully, adding different depths of flavor and texture.
Is there a vegetarian version of the Mushroom Sandwich Melts Recipe?
Definitely! Simply omit the bacon or substitute it with smokey vegetarian bacon or sautéed smoked paprika-seasoned tofu for a similarly bold flavor.
Can I prepare the filling ahead of time?
Yes, you can make the filling a day in advance and store it in the fridge. When ready to bake, just spoon it onto your toasted baguette slices and bake as directed.
What cheese works best if I don’t have a Mexican cheese blend?
A combination of mozzarella, cheddar, and Monterey Jack cheeses makes a great substitute, providing that perfect melty and flavorful cheese blend.
How do I make the baguette toasts perfectly crispy?
Slice the baguette about 1/2 inch thick and lightly toast them in the oven or toaster before adding the filling. This gives them a sturdy, crispy base that won’t get soggy after baking.

Dairy
- 2 Tbsp unsalted butter

- 2 Tbsp mayonnaise
Meat
- 8 oz bacon, chopped into thin strips
Bread and Seasoning
- 2 soft French baguettes, sliced into 1/2″ thick toasts
- 1/4 to 1/2 tsp salt (or to taste)
- 1/4 tsp black pepper (or to taste)
Instructions
- Prep and Sauté Onion: Preheat your oven to 350˚F and line a large baking sheet with parchment paper. Heat a large non-stick skillet over medium heat, add 1 tablespoon of butter, then sauté the diced onion, stirring frequently until soft and lightly golden, about 5 to 7 minutes. Add the pressed garlic and cook for another minute until fragrant. Transfer the onion and garlic mixture to a mixing bowl.
- Sauté Mushrooms: Using the same skillet over medium-high heat, add 1 tablespoon of butter and sauté the diced mushrooms until they are soft, and their juices have evaporated, about 10 to 12 minutes. Transfer the mushrooms to the mixing bowl with the onions and garlic.
- Cook Bacon: In the same skillet, add the chopped bacon and sauté until browned and crispy, approximately 7 minutes. Transfer the cooked bacon to a paper towel-lined plate to drain excess fat, then add it to the mixing bowl with the other ingredients.
- Combine Filling: Add 2 1/2 cups of finely shredded Mexican cheese blend, 1/4 cup chopped parsley, 2 tablespoons mayonnaise, salt (1/4 to 1/2 teaspoon), and black pepper (1/4 teaspoon) to the bowl with the mushroom, onion, and bacon mixture. Stir everything thoroughly to combine all the flavors.
- Assemble and Bake: Spoon the mixture generously onto the toasted 1/2-inch thick slices of French baguette, mounding and shaping it with the spoon. Arrange the filled toasts on the prepared baking sheet. Bake in the preheated oven at 350˚F for 15 minutes until the cheese is melted and bubbly. Garnish with additional fresh parsley if desired and serve warm.
Notes
- Ensure mushrooms are well cooked and their liquid evaporated to avoid sogginess in the sandwich melts.
- Adjust the salt and pepper according to your taste preference. Be mindful that the bacon and cheese add saltiness.
- You can substitute Mexican cheese blend with a mix of Monterey Jack and cheddar if unavailable.
- Serving these melts warm enhances the flavor and texture, as the cheese remains beautifully melted.
- For a vegetarian option, omit bacon and consider adding sautéed bell peppers or spinach as a substitute.
