Mushroom and Fontina Tartine

Jump to Recipe

I’m obsessed with a lot of things. Avocados, cookies, cheese and mushrooms. My love affair with mushrooms started a few years back in culinary school and I have been obsessed ever since. They are just so flavorful, meaty and versatile and you can use them in just about anything.

Recently, because it’s been so darn cold here in LA (I know we are total wimps when it comes to weather – but I just can’t help it!) I’ve taken to roasted mushrooms. That way I can sit in front of the oven and warm up as the mushrooms are roasting.

Once the mushrooms are done roasting, you can use them in any variety of things… but one of my favorites is a cheesy tartine. I just take a few pieces of toast, give them a swipe of butter, let them toast up in the oven, and finish it off with a handful of shredded fontina cheese on top. After the cheese has melted, they get a hefty spoonful of the roasted mushroom mixture and a sprinkle of salt and pepper.
