“Better than Garlic Mushrooms” CRISPY Garlic Mushroom Fritters

These crispy garlic mushroom fritters, known as buñuelos de champiñones, are possibly the most flavorful fritters ever. We’re talking a ton of great flavors, simple everyday ingredients, and done in about 30 minutes. Serve them as a tapas appetizer, next to some marinated olives and a couple of ice-cold beers for the best moment in your day.

CRISPY Garlic Mushroom Fritters

To make these fritters, I used white button mushrooms. But you can use any type of mushrooms you like. Either way, I sautéed the mushrooms for 8 to 10 minutes before adding them to the batter, instead of adding them raw. As it gives the fritters a bigger depth of flavor.

I served these mushroom fritters next to a simple mayo aioli that truly elevates this dish. Made with just mayonnaise, garlic, lemon juice, and olive oil. You can also add in some hot smoked paprika or a dash of crushed red pepper for a spicy kick.

TIPS & TRICKS to Make this Recipe: For the batter, I used club soda. You can also use sparkling or beer. If you see your batter is too thick, just add in some whisked egg or more liquid. You can also make the batter ahead of time. As it will hold for up to 2 to 3 days in the fridge in an airtight container.
