Over the past couple of years, there have been only a few food trends that have dominated Instagram and TikTok feeds as much as tinned fish. This once humble supermarket staple has seen a real resurgence, thanks in large part to companies modernizing the category.

Among the rising innovators is Fishwife Tinned Seafood Co., a woman-founded brand that aims to provide premium ethically sourced tinned seafood. And right now, you can score one heck of a discount on its wildly popular smoked rainbow trout at Costco.

  • Price: $20
  • Why I Love It: This 3-pack is more than $10 less than you'll find it on Fishwife's website. It's perfect for holiday gifting and gatherings.

Why I Love Fishwife's Tinned Seafood

According to Fishwife’s website, the rainbow trout is raised on an Aquaculture Stewardship Council (ASC)-certified sustainable farm in Denmark. The fish is slow-smoked in small batches over beechwood before being packed by hand in extra-virgin olive oil, all in a “micro-cannery” near Copenhagen.

This kind of premium product typically comes with a high price tag, which makes Costco’s $20 three-pack of Fishwife Smoked Rainbow Trout an incredible deal. On the Fishwife website, that same three-pack retails for $33, plus shipping.

At Costco’s price, you can afford to grab a few multi-packs, which are perfect for holiday gifting or for having on hand during the holidays for a party appetizer or a quick lunch. 

How to Use Smoked Rainbow Trout

I’m already thinking about stirring this flaky, buttery fish into a dip with cream cheese and chives, and serving it alongside crackers and a relish tray at a holiday party. These chic tins also look great on a charcuterie board or grazing table, and they don’t require any effort to get something nice on the table—even if you just pop open the tin and serve it with some stone-ground mustard and a sleeve of crackers, you still have a seriously fancy snack.

The cooking fans in your life will love a tin gifted to them. Pair it with a cute serving plate and a nice spice blend, or simply tuck a couple of the vividly colored boxes into a stocking.

Fishwife’s Smoked Rainbow Trout is now available at a number of Costco locations. And keep your eyes peeled: Some eagle-eyed shoppers have also spotted the brand's luxurious tuna belly on shelves.
