Mushroom Croquettes

The first time I had mushrooms croquettes was at a Spanish tapas restaurant and I had to recreate it. They are surprisingly easy to make and taste like crispy explosions of mushroom soup. The most important part is making sure you cook the filling thick enough so that you can shape them easily afterwards.

The perfect mushroom croquettes filling

Cooking process

After you have added flour and milk into the pan, you will see that the mixture will start to thicken. You will want to cook it for another 10 minutes or so until it starts t move like 1 large blob when you stir it in a pan. This is when you know it is thick enough. After it has been cooled, it should look like 1 block of jello.

What happens if the mixture is too runny?

If the mushroom filling mixture is too runny, then you will have a very difficult time shaping it after it has cooled. A good way to tell that it is thick enough is if the mixture moves as “one” in the pan while stirring. Once it has had a chance to cool down in the fridge, it will solidify and be easy to shape afterwards. Once cooked, the mixture will soften and become runny again like mushroom soup.

How to bread them

The breading process is very standard which is flour, egg wash, and breadcrumbs. The only difference from what I normally do is in the breadcrumbs. Most of time, I use panko breadcrumbs, but for this recipe you will want to use plain breadcrumbs. This is because they are more fine and can cover more surface area as opposed to panko which is more coarse.

What sauce to serve with mushroom croquettes?

My go-to and one of my favorite sauces to make is a garlic sauce which tastes just like the ones you can get at shawarma restaurants. The recipe is very simple, it’s just a combination of mayo, grated garlic, and lemon juice. Trust me, you will put this on everything.
