    cheesy mushrooms on toast

    What is mushrooms on toast?

    Mushrooms on toast is a simple dish from Britain. It is traditionally kept very simple, just sauteeing up some mushrooms and eating them atop toast. It's eaten as a filling snack or a light meal rather than an entree.

    This mushroom toast is inspired by, but is a bit different than the traditional British meal. We add lots of flavor with swiss cheese, dijon mustard, and fresh thyme. We also broil the mushrooms and cheese over the bread and toast the whole thing together.

    The mushrooms

    For this recipe we love baby bella or cremini mushrooms! They are the perfect size when sliced to saute and then pile on the toast. Plus, they have a more intense flavor than white button mushrooms.

    If you can't find baby bella or cremini mushrooms, try:

    • White button mushrooms: these are younger versions of cremini mushrooms and will have a slightly more mild flavor. Slice these the same as you would creminis.
    • Portobello mushrooms: these are more mature versions of cremini mushrooms and will have a slightly more intense flavor. You'll want to dice portobellos rather than slice them for this recipe.

    Have you tried our caprese portobello mushroom pizzas recipe?

    The bread

    We like to use thick slices of rustic french bread for mushrooms on toast! You'll need to use bread that is sliced about an inch thick and that will hold it's shape when topped with sauteed mushrooms. Look for artisan loaves of bread that have crunchy crusts that you can slice yourself, usually found in the bakery section of your grocery store.

    If you can't find french bread that has a thick crust, try:

    • Sourdough bread: this will have more of a fermented flavor, but will still be delicious!
    • Any artisan, crusty bread: Any bread will work for this recipe as long as it has nice, thick crust. Try Cooking Classy's no knead bread at home!

    The cheese

    We love swiss cheese for it's funky, yet mild flavor and meltability. We recommend buying a block of swiss cheese and grating it yourself for the best flavor. We recommend Tillamook swiss cheese!

    If you can't find swiss cheese, try:

    • Gruyere cheese: more on the expensive end, but oh so flavorful!
    • Jarlsberg cheese: very similar to swiss cheese, but even more flavorful.
    • Sharp white cheddar cheese: A super sharp white cheddar cheese will have a different flavor, but will still be delicious and melt well.

    Here's what you'll need

    Ingredients:

    • Butter: for sautéing the mushrooms. You can use olive oil as a replacement.
    • Cremini mushrooms: see the section above titled "the mushrooms" for details and substitutions.
    • Fresh garlic: for the sautéing the mushrooms.
    • Thick, rustic crusty bread: see the section above titled "the bread" for details and substitutions.
    • Whole grain dijon mustard: we love Maille Old-Style mustard.
    • Swiss cheese: wee the section above titled "the cheese" for details and substitutions.
    • Fresh thyme leaves: for serving.
    • Salt and pepper: for seasoning.

    Equipment:

    • Sharp knife: for slicing and chopping.
    • Cutting board: for slicing and chopping.
    • Medium sized frying pan: for sautéing the mushrooms. Here's our favorite!
    • Stirring utensil: for sautéing the mushrooms. We like wooden utensils.
    • Spreading utensil: for the mustard.
    • Cheese grater: for grating the cheese. Here's our favorite box grater.
    • Baking sheet or broiling pan: for broiling the toasts.

    How to make it

    Full instructions are listed in the recipe card at the bottom of this post.

    Mushroom toast is amazingly simple, but loaded with flavor. Since there are so few ingredients, you'll want to choose very high quality produce and products. Very fresh baby bella or cremini mushrooms, rustic bread with a hearty crust, whole grain dijon mustard like Maille old style mustard, and aged swiss cheese.

    Chop your mushrooms and garlic and heat up a frying pan. Melt the butter and sweat the mushrooms. Add the garlic and saute together until the mushrooms are very brown and starting to crisp.

    Turn on the broiler and build your mushroom toast. Spread the mustard on the bread, top with a bit of cheese, top with mustard, then top with more cheese. Broil until the cheese is melted and starting to brown. Sprinkle with fresh thyme, salt, and pepper.

    Additional toppings for mushrooms on toast: fried or poached eggs, crispy chickpeas or beans, spinach or kale, walnuts, or even roasted cauliflower or broccoli!

    FAQs

    How do I make this vegan?

    Replace the butter with olive oil or vegan butter. Omit the cheese or use vegan mozzarella.

    Can I make this a sandwich?

    Of course! Brush some olive oil or butter on a slice or two of bread and broil them along with your toasts. Add the additional bread to the top of your toast and voila, a sandwich.

    Can I omit the mustard?

    Yes.

      This toast is yummy! I especially love the mustard. I like to top mine with fresh chopped spinach. This is perfect for Meatless Monday with a cup of homemade tomato soup.

      Quick question, do have a recommendation for a Swiss cheese substitute? I am really not a fan.

        You could use shredded mozzarella, cheddar, or even havarti! Any melty cheese that you like will taste great.

      This was delicious, everyone loved it! I just used regular Dijon as that's what i had, have used the Maille old style in the past, it's delicious, just not something the other members of the house like at this point.

      Well I do love mushrooms...and bread. What a great alternative to bruschetta or garlic bread. This would work as an appetizer, or a great side to pasta, salad or soup.
