Mushroom Burger with Horseradish Cheese Sauce – juicy beef, sautéed mushrooms, and a creamy, spicy cheese sauce on a soft Hawaiian roll. Bold flavor, zero regrets.
At this point you all know how much I love to make burgers.
Just putting the elements together to make one taste profile is fun for me. I absolutely adore it. You will love this one if you’re a mushroom fan; I happen to adore them. This is not a very complex burger. Complex in taste, yes.
This isn’t your standard “burger night” situation. This is what happens when a regular beef patty meets its overachieving alter ego — seared with Moore’s, piled high with buttery sautéed mushrooms, and drenched in a creamy, fiery horseradish cheese sauce (thank you, Cabot).
Then I went and tucked the whole glorious mess into a Hawaiian roll, because I like my burgers with a little sweetness to balance out the bite. Arugula keeps it from feeling too indulgent (you know, for balance).
It’s savory, spicy, melty, and messy — in other words, everything a burger should be. You’ll need napkins. And maybe witnesses.
The only time consuming element is the cheese sauce, and it’s not really difficult at all. You basically begin my making a roux and add the cheese. The mushrooms are so important here. Please, for the love of God, don’t use canned mushrooms. You’ll ruin this. It may be tempting, but it’s really not worth it.
The cheese I used is Cabot’s Horseradish Cheddar. I’ve found so many things to put this cheese on – it’s not quite as hard as most white cheddars.

Cabot rocks; they couldn’t make bad cheese if they tried.
I did add bacon to this, and it adds a nice salty crunch. As far as the bun, I chose Hawaiian rolls. I typically don’t use them frequently because they’re sweet as hell. However, the horseradish cheese combined with the mushrooms and bacon offset it really well. It’s a fantastic flavor combination. In other words, this tastes absofuckingmazing.
With the cheese, you can add as much or little cayenne as you want. I personally like heat.
But you knew that.
I had to do the obligatory bite shot with this one.
