Healthy Fish and Chips

Healthy Fish and Chips Recipe

As an English man I was brought up on deep fried fish and chips on a Friday night with the family.  Then when my family and I went down to Devon on holiday we would make a special trip to Rick Stein’s restaurant for the best fish and chips on the planet.  Then I completed my degrees in Nutrition and unfortunately I learned how horrifically high in saturated and trans fats this dish is, not to mention the high calories.  However the recipe we have put together switches the potato chips for sweet potato wedges and the batter has a slight variation to but is not deep fried in batter, it is grilled in the oven saving fat and calorie consumption.  Here are a few questions we have been asked in the past about cooking a healthy fish and chips dish.

Which oil should I use when cooking fish and chips with?

This is one of the most popular questions we have been asked over the years.  The media are quick to promote the latest FAD oil as well as celebrity cooks and before you know it the public are completely lost as to which oils are the best.  Lets start by focusing on the king of oils OLIVE OI.  For hundreds of years olive oil has been used in the Mediterranean cuisine as the superior oil, this is oil we choose nine times out of ten.  It has a high monounsaturated fat content, meaning that it is quite heat resistant as the general rule is the thicker the oil the better it is.  The cheap olive oils really aren’t good for cooking with.   Other relatively heat resistant oils are grape seed oil, canola oil, rice bran oil and avocado oil.   Any oil that has a high polyunsaturated fat content is going to smoke easily and turn into a trans fat at high heats i.e. sunflower oil or flax-seed oil.  For this healthy fish and chips dish we have used extra virgin olive oil from Cobram Estate in Victoria.

Are sweet potatoes better for you than traditional white potatoes? 

This is a difficult question as both potatoes have got great nutritional properties.  Sweet potatoes are high in beta-carotene, potassium and fibre and white potatoes have a high vitamin c and potassium content.  The biggest difference is the starch (carbohydrate content).  White potatoes do have more calories pound for pound and tend to be used more in the processed food world as crisps and chips.  We have chosen to use sweet potatoes in our healthy fish and chips recipes as we prefer the flavour and colour.

Top Tip for cooking fish in the oven:

  1. Make sure you have a fan forced oven, this helps to evenly cook the fish
  2. Always add lemon juice to fish, it maintains moisture levels and balances out the fishy taste.
