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.

rolled out oatcake dough

Roll out and cut out biscuits!

freshly baked sardine oatcakes

Place dog biscuits on baking tray and place into a preheated oven at 190°C (370°F) for around 20-25 mins.

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. Thanks Liz (March 12th) for the banana tip. Both my dogs LOVE these & I will be trying the banana version. I’ve made them with sardines in oil often they also work Very well with sardines in tomato too (I add a smidgen of oil)

    Jamie, your recipes are Fantastic, Desperately want to try the Pig head recipe but apparently I’m not allowed to buy the head (several butchers have said the same)

  2. its about the sardine oatcakes do you have to freeze them will they not keep in the fridge and can you substitute tuna for sardines they don’t agree with the dog

    • Hi Margaret!

      I’ve never remotely stored any of the dog treats long enough to know how long they last so I just recommend storing them in the freezer. The dryer they are the longer they will last. Tuna will work fine.

  3. Can I use plain flour with added oats? Because I can’t find any wholemeal flour.

    • Yeah that’ll be fine.

  4. Thank you for your recipes. Made these and the liver treats for my Beagle Bonnie. She loves them and recalls were amazing on our walk today

    • Hi Debbie. Glad to hear it! Thanks for letting me know! 🙂

  5. thank you, thank you, thank you – love the recipes on your site and have shared them with lots of my doggy friends. This one is a particular favourite of mine even if it does smell the house out (especially if your burn a batch – oops :)) have also tried the cheese biscuits and the ginger ones. Going to bake the Liver cake tonight and see how that goes.

    I volunteer at a rescue center and some of the dogs are really fussy about shop bought treats however i always come away with an empty bag when i take these in to them. I always have to make sure i keep some back for my own pooch seeing as she has had to smell them cooking!

    I bought a selection of mini cookie cutters so get well over a hundred out of a batch with means they go further with the dogs.

    Love the fact that you can freeze them as well.

    Thanks x

  6. Great recipe Jamie, I would recommend making this a thin biscuit to be broken into smaller pieces (unless of course you have a really small pastry cutter)
    I’m using these to replace P@H brand Mini Bones which are OK but yours knock them out!
    Dexter our 9 month old Irish Water Spaniel is drooling for them by the bucket full, gonna gently try his sensitive stomach on a few Liver ones next
    Thanks, Phill

  7. We have a 3 month old golden doodle who has teeth like a piranha. I like to give him a special treat at bedtime to make his gums feel better. I bought puppy teething treats, but I am having a hard time finding them made in the U.S.A. So I decided to try to duplicate them. Not possible. However, I have found that this site has lots of substitutes, and it will certainly help my pocketbook. I met a woman in the pet shop who had what appeared to be an adult golden doodle. I asked her when he stopped mouthing, and told her someone had told me it would happen at 4 months. She almost fell on the floor laughing. Her golden doodle is 2 and still mouths. So I need these treats.

    • Hey, I just read my email, and frankly I think I was pretty insulting without intending to be. I did not stop to think this website was from the U.K. We lived there for a year up in Durham, and frankly I have never seen people so careful about food. Even Eric, the gardener, told me that it was against the law to use anything that was opposed to organic in his gardens. I went to the store to buy from non-quick-cooking oats, and I went to the discount store. There is a wonderful one of these at the bottom of the hill in Durham. Anyway, I wound up buying a 5-pound container of the oats because that was the only size the non-quick ones came in. I will be using these for a long time or making a lot of cookies.

  8. Hiya, made these for our older dogs, they love them! Have a new pup on the way was just wondering at what age we could start giving her these?
    Thanks

    • Hi Charlotte

      These biscuits will be fine for pup, but cause it a ‘new food’ to pup give small bits to begin with.

  9. Made a batch of these today for my cocker pup as the vet advised some extra bran. Really easy to make and Cotto loves them…thanks for the great recipe

    • Thanks Evelyn. This is my fave recipe!
