The original sardine oatcake recipe

This is personally my favourite recipe on my blog, partly cause it was the first original treat I made myself that worked out.  If you need super high-value treats – you’ve just found them!  Your dog will love these oatcakes; they are tasty, healthy, smell great, and just so easy to make!  And from preparation to cooking time they take less than one hour!

When I was thinking about a new recipe I could come up with I thought about making a type of oat based doggy flapjack then found that oatcakes were even easier to make and the perfect treat recipe to use fish!

I’ve taken these out with me several times when I’ve been dog walking and they are great for getting the attention of a dog who’s mind wanders when out for a walk!

Very simple to make, all you need is 6 ingredients and a biscuit cutter.

 

INGREDIENTS

  • 2 tins of sardines in oil (2x120g)
  • 60g (1/3 cup) of wholemeal flour
  • 300g (1 1/3 cups) of oats
  • 150ml Chicken broth (homemade broth is best)
  • 1 egg

METHOD

broth in a jug

Make around 150ml (1/4 pint) of broth or stock.  Chicken will do.  If using cubes get the low salt ones.

sardines in a mixing bowl

Add the two tins of sardines to a bowl (including the oil)!

mashed sardines

Mash the sardines thoroughly with a fork!

egg

Add an egg

oatcake ingedients in a bowl

Add the 300g (10oz) of oats and 60g (2oz) of wholemeal flour

adding broth to mixing bowl

Add a little of broth to bowl.  To start with try adding 1/3 of your broth.

sardine oatcake dough ball

Mix ingredients with your hands and make a dough ball!  Too dry?  Add more broth.  Too wet?  Add some flour or oatmeal.

If you’ve made these before, you will know what to expect

How to store

As a general guide if meat protein is present in recipe then it will last around 3 to 5 days stored in a cool place.  If it has second class protein in it eg. cheese, lentils, eggs, etc, then they will store for about 10 days in a cool place. If there is no meat or second class proteins present then it will last around 3 weeks before they go soft like human biscuits.

  1. I’ve made these countless times, sardines in tomato work well too. Tomorrow I’m replacing the sardines with finely chopped Chicken livers, I’ll let you know how well they work

  2. I’ve just made a batch of these sardine biscuits and Kudu sat by my side smelling the kitchen air as they cooked. He loves them, and I’ll share them with Kudu’s lovely doggie walker tomorrow so that the other dogs can enjoy this superb treat.
    Thank you Jamie.

  3. Is there a way to make this a hard biscuit? I made these and while they seemed firm when my dog ate one it just crumbled into crumbs in her mouth.

    • Hey, you could try cooking them longer at a lower heat to help dry them out, that would make them harder.

    • When I made them I accidentally transposed the amounts for the whole wheat flour and the oats. Mine were made with 1 1/3 cup flour and only 1/3 cut oats. They came out perfect. Took an extra splash of water to make it dough.

  4. Hi Jamie fab recipe for sardine oatcakes thank you. My dog was 2 today so made this as a treaty does cooked it in a tin then cut up like flapjack!! Max (lab)loved it as did our springer Myah. Gave some little bits to their puppies who are only 5 weeks old they loved it too. 🙂

    • Hey Melissa. Thanks for your feedback and happy birthday to Max. This is my fave recipe!

  5. I’ll give these a go tomorrow I’ve always got sardines in oil in as I feed some feral cats by me ( they are only 39p from b&m) . Let’s see if my girls like them the 10 week old puppy will eat anything she can but the 5 year old is more selective x

    • Hey, I’m certain your 5 year old will love these, they are a favourite of all dogs, choosy or not.

  6. ohhhh I’m going to try this, my boy loves sardines…….. i guess i can use spelt flour or coconut flour? i buy the ones in spring water, so can i use coconut oil and or flaxseeds? to bind?

  7. Only in stupid quantities, Sophie.

  8. I’ve just made my first batch of these. Definitely a new favourite. I shall have to bulk-buy sardines in the future, I think!
    Willow and Shadow say thank you 🙂

    Next stop, tuna loaf…

    • Hey Fiona. Aww thanks for that. I’m so glad Willow and Shadow like them.

  9. Sardine oatcakes – fantastic! – say Belle & Coco.
