Equipment

  • Deep Fat Fryer
  • Mixing Bowls
  • Wire Cooling Rack
  • Baking Tray
  • Slotted Spoon

Ingredients

  • 3 Large White Onions
  • 350 g Buttermilk
  • 150 g Plain Flour

Beer Batter

  • 225 g Plain Flour
  • 75 g Cornflour
  • tsp Baking Powder
  • 350 ml Cold Beer See Notes

Buttermilk Ranch

  • 1 Banana Shallot
  • 150 g Buttermilk
  • 150 g Mayonnaise
  • 100 g Sour Cream
  • 1 Clove Garlic Grated
  • tbsp Finely Sliced Chives
  • 1 tsp Lemon Juice

Instructions

  • Trim the top of each onion off then cut into 1 cm wide slices, stopping just before the root. Gently remove the outer skin.
    I find it easier to peel the skin off after slicing the onions but you can take it off before if you'd prefer.
  • Carefully separate the onion slices into rings, discarding any that are broken or very small.
  • Next, place the onion rings into a bowl then pour over the buttermilk. Gently stir the onions with your hands, so that each piece of onion is coated then refrigerate for 1 hour.

Buttermilk Ranch

  • Peel the shallot, cut into a very fine dice then place into a mixing bowl.
  • Add in the buttermilk, mayonnaise, sour cream, garlic, chives & lemon juice, season with salt & pepper then stir to combine. Refrigerate until needed.

Dredging

  • Preheat a deep fat fryer to 175°c/347°f.
  • Place the plain flour (150g) into a mixing bowl.
  • Next, take an onion ring out of the buttermilk, shake off the excess then toss in the flour. Place onto a wire rack (set over a tray) then repeat with the remaining onion.

Beer Batter

  • Place the flour, cornflour & baking powder into a mixing bowl, whisk together then season with salt & pepper.
  • Pour in the beer then whisk until just combined,
    Once made, the beer batter should be used straight away!

Frying

  • To cook, take an onion ring & dip in the batter. Allow any excess batter to drain off then carefully lower the onion into the hot oil. Repeat with a few more onion rings.
    If you dip the onion into the hot oil halfway (carefully!) & hold it there for a couple of seconds (or until it starts to float), it won't stick to the basket!
    Depending on the size of your fryer, you should be able to cook 3-4 onion rings at a time.
  • Cook for 5-6 minutes, flipping with a slotted spoon halfway through. Once cooked the batter will be crispy & a deep, golden brown.
  • Lift the onions rings out of the fryer, let the oil drain off for a minute or so then transfer them to a plate lined with a piece of kitchen roll. Repeat the cooking process with the remaining onion rings.
  • Season the onion rings with sea salt then serve hot with the buttermilk ranch dipping sauce.

Notes

1. Portions - This recipe makes enough onion rings for 8 generous portions, plus plenty of ranch sauce. Feel free to make half the recipe, if you'd prefer. To make half the batter, use a heaped tsp of baking powder.
2. Beer - For a light, crispy batter I’d recommend using either a lager or a pale ale. Make sure that the beer is cold before using. This is the secret to super crispy batter!
3. Batter - For the best results, the beer batter should be used straight away. Make sure not to overmix it! For a alcohol-free batter, use sparkling water instead of beer.
4. Deep Frying - A deep fat fryer makes cooking the onion rings a lot easier! If you haven't got one, heating a pan of veg oil up on the stove will work as well. Just make sure to do this very carefully!
5. Buttermilk - Soaking the onions in buttermilk gives them a mild, tangy flavour. If you haven't got any buttermilk, regular milk or ice cold water will work as well.
