Health Benefits

I recently launched a web series called Food Facts Friday, where I spotlight a “human food” that’s healthy for our canine companions. Sardines earned a spot on the list! They’re rich in Omega-3 fatty acids, protein, various vitamins, and key minerals. Thanks to their large nutrient profile, these tiny fish have been linked to many health benefits. 

Experts say they benefit:

  • Immune system
  • Heart 
  • Brain
  • Kidneys
  • Eyes
  • Digestion
  • Skin and coat

Sardines: When selecting the perfect can of sardines for this recipe, look for one that’s boneless, skinless, plain (no flavors added), no salt added, in water! This is the brand I use:

Baking Sheet: Any baking sheet will do! If you’re in the market for new baking sheets, I use the Nordic Ware set. They’re super affordable and good quality.

Parchment Paper: I stockpile parchment paper because I use it for pretty much every dog treat recipe. I personally like the pre-cut sheets by Reynolds, but any parchment paper you have is great!

Kitchen Gloves: Okay, you don’t actually need kitchen gloves to make this recipe. But, since we’re dealing with stinky fish, I like to cover my hands. 

Sardine Crisps Recipe

Sardine Crisps


  • 1 can sardines (boneless, skinless, plain, in water)


  • Preheat oven to 400ºF and line a baking sheet with parchment paper. Set that aside. 
  • Drain canned sardines.
  • Carefully remove sardines from the can and split in half, lengthwise. (See video above for example). Some sardines may break, depending on how tightly packed the can was. That's okay -- you can still use the smaller pieces. But, try to do this step carefully to keep each piece intact. 
  • Blot sardine halves with a paper towel to pull out any excess moisture and transfer to the baking sheet.
  • Bake for 25-30 minutes, or until crunchy.


Store in an airtight container in the refrigerator for up to 4 days.
