Cheesy Mushroom Toast With Mustard and Thyme

I spotted a version of this recipe on the Maille mustard website. Ashamedly, I adapted their recipe using the mustard of a competitor. I know; I feel terrible about it. But, in my defense, I have three different kinds of Maille mustard in my fridge, including a giant crock of stone ground, so it isn’t that I’m not a staunch supporter of theirs, my head was just turned by a sexy new kid on the block. Boar’s Head’s (This is not a sponsored post; I am not being paid to mention them.) Pepperhouse Gourmaise is a yummy mustard blend containing white, green, and pink peppercorns. I’m on my second bottle of the stuff. Seriously, I could eat it with a spoon. Because of the peppercorns, it does give off some heat, so if you think that’s going to bother you, use the mustard of your choice.

I love this mushroom toast! I had a slice for lunch, made it again, and cut it into portions to serve as a snack, and offered up smaller slices for a brunch. I don’t know anyone who's tried this who hasn’t fallen absolutely in love. Because mushrooms have a woodsy, meaty taste, I always add Montreal Steak Seasoning when I cook them. It adds so much flavor and earthiness. Give this a try. How many recipes are as versatile? So good!

Cheesy Mushroom Toast With Mustard and Thyme

Based on a recipe from Maille

2 T. butter

4 c. sliced baby bella or cremini mushrooms

2 cloves garlic, finely minced

1/8 t. Montreal Steak Seasoning

2 slices thick rustic bread (I used Pane Turano from Aldi)

3 T. Boar’s Head Pepperhouse Gourmaise

1 c. shredded Gruyere

Pinch dried thyme leaves, optional

Salt and pepper, if desired

Melt the butter in a sauté pan over medium high heat. Add the mushrooms and sweat, stirring occasionally, about 3 minutes. Add the garlic and sauté, stirring often, until mushrooms are browned and all liquid has evaporated.

Preheat the broiler. Spread the mustard on one side of each piece of bread. Top each slice with a sprinkle of cheese. Evenly top with the mushrooms and then top each with another generous sprinkle of cheese. Broil until the cheese is melted and starting to brown, about 2 minutes.
