Spanish Onion & Cheese Fritters | Seriously GOOD 20 Minute Recipe

These Spanish Onion & Cheese Fritters, known as Buñuelos de Cebolla y Queso Manchego, are packed with flavors, seriously easy to make and all done in about 20 minutes. Serve them as a tapas appetizer, as they do in Spain, or even as a side dish next to a garlic potato omelette.

Spanish Onion & Cheese Fritters
To make this recipe I used regular yellow onions. But you can use any type of onion you like. For the cheese, I used a Spanish Manchego that was aged for 6 months. But once again, you can use any cheese you like or whatever you have on hand.

Spanish Onion & Cheese Fritters
To fry the fritters I used extra virgin olive oil. As it adds an incredible depth of flavors. You can use other oils here if you like, such as virgin olive oil, sunflower oil or even canola oil. Either way, make sure to fry the fritters on a medium heat and nothing higher. Otherwise, they will brown too quickly and not fully cook.

TIPS & TRICKS to Make this Recipe: You can make the batter ahead of time and add it to the fridge. It will hold for up to 3 days in an air-tight container. These fritters can be served piping hot or even at room temperature.
