For truly amazing mushrooms, the trick is to just let them cook. The best way to cook them is to use a higher heat and once you place them in a dry pan – leave them!

Mushrooms are 80-90% water, so when you cook them quickly over lower heat and move on with a dish, that water hasn’t cooked out and you’ll end up with soft, spongy mushrooms.

Letting mushrooms cook longer over higher heat allows the water to cook out, leaving you with a ‘meatier’ mushroom texture. Which is delicious.

Ingredients

Ingredients for mushroom toast on a white marble counter.
  • bread: I like sourdough bread for this recipe, the flavors go well together.
  • mushrooms: I use cremini mushrooms, also called baby portobellos. These are my favorite, easily available, and budget-friendly mushrooms.  You can use your favorite type of mushrooms or a mix of mushrooms such as white button mushrooms or shiitake mushrooms.
  • shallot + garlic: shallots have a milder taste than onions and blend well with the mushrooms in this recipe. Fresh zippy garlic is always good. Add two garlic cloves if you’re a big garlic fan.
  • red pepper flakes: for a bit of spice. Omit if you prefer.
  • balsamic vinegar: Gives a tangy twist to the mushrooms and a nice color.
  • dried thyme: for savory herbiness.
  • Parmesan cheese: For umami deliciousness, cuz cheese is always good!
  • fresh parsley: for freshness.

Substitutions

  • bread: use another type of bread if you’d rather.
  • shallot: use onions instead or omit it
  • dried thyme: try rosemary or oregano instead
  • balsamic vinegar: you can skip this and garnish with balsamic glaze instead if you have that on hand instead.

Instructions

Prep Tips

  • Clean whole fresh mushrooms by simply wiping them with a damp paper towel and then slice them.
Mushrooms and shallots are added to a skillet.
  1. Heat a large skillet over medium-high heat. Add the sliced mushrooms to the dry pan in a single layer. You can add the shallots now or after the mushrooms have cooked.

  1. Let the mushrooms cook for a few minutes, undisturbed. Stir and let cook for another few minutes. The mushrooms will let out their moisture and shrink in size as they cook. 

Once they are lightly golden brown, turn the heat down to medium heat and add a drizzle of oil and the shallots, and cook them for a few minutes, until softened.

This is a good time to toast the bread and butter it.

Next, add a little butter and let it melt. Remove from heat. Season with salt and black pepper.

Tips for making toast with mushrooms

  • Use your favorite mushrooms. I love cremini mushrooms so that’s what I usually use because I buy them each grocery shop.
  • Customize this recipe by using onions instead of shallots or dried rosemary or oregano instead of thyme.
  • Try spreading the toast with cream cheese or hummus first.
  • Let the mushrooms cook long enough that they let out their moisture – this results in a really good texture in the mushrooms.

What to serve with mushroom toast

I love to make this more of a filling meal by adding a fried egg or poached egg on top. This makes a fancy-looking brunch dish for get-togethers. Serve this toast with a side salad for a light and easy meal during the week.

Try cottage cheese toast or avocado toast with feta next.

Storage

This toast is best eaten when made but the mushrooms can be made ahead of time or made in large batches to meal prep them.

Store the cooled mushrooms in an airtight container in the fridge for about 4-5 days.

Reheat in the microwave or a skillet until hot and then add to freshly toasted bread.
