Add vegetable oil to a deep fryer or to a Dutch oven until it reaches about 4 inches up the sides. Heat oil to 375°F.
Make the batter
In a large bowl whisk together 1 cup all-purpose flour, 1 ½ teaspoon baking powder, ½ teaspoon garlic powder, and ½ teaspoon onion powder.
Stir in 1 cup buttermilk and 1 cup club soda or beer until smooth.
Dip the curds, and fry
Add 1 pound cheese curds to the bowl and coat them in the batter.
Carefully add the cheese curds a handful at a time, not touching into the hot oil. Place the bowl back into the fridge so everything stays cold.
Let them fry for about 1 minute, flipping halfway through until lightly golden brown.
Remove and devour
Take them out of the oil, letting excess oil drip off. Place them on a paper towel lined plate to soak up any excess oil.
Place the cheese curds on a wire rack that is placed on top of a sheet tray while you fry the remaining curds.
Serve immediately with marinara sauce and ranch or blue cheese for dipping.
Notes
Variations:Other spices you can add to the batter: cayenne pepper, chipotle powder, or smoked paprika.I do not add salt to the batter because the cheese curds are already very salty. This may vary by brand, so taste a cheese curd first to check the salt level. Add up to ½ teaspoon of fine sea salt to the batter if they need it.What to do with leftoversThese are best eaten the same day. But, to reheat leftovers I suggest placing them back into the fryer until warmed through, 30 seconds to 1 minute.Freezing instructionsThese can also be frozen for up to 3 months. To heat, do not bring to room temperature, place the frozen curds right into the hot oil for a minute or two until warmed through.
