SARDINE SANDWICH RECIPE
This sandwich takes it up a notch yet it's completely realistic and achievable to make with ingredients you likely have on hand. It will easily become one of your favorite canned sardine recipes.
This sardine bread sammy has a little kick from the spicy mayo, which we pair often with canned sardines. Something about the creamy flavor-rich hot sauce creates a balance that pairs so well with these little fish! Combining that with cucumber and tomatoes that are kitchen staples, is the perfect crunch on top. I like to use toasted bread to add an extra crunch and create a stable surface.
These little fish have more going for them than against them. They're full of nutrients, protein, fatty acids, and other vitamins and minerals - which is one of the biggest perks of eating seafood in general. My favorite perk, is that they're shelf stable and can easily be whipped up for a quick protein rich and healthy meal.
We love quick and easy meals and have quite a few of quick seafood recipes on here, and canned seafood makes it much easier when you have just a few minutes to prepare a quick meal with minimal effort. Some of my favorites are this tuna pesto pasta, tuna dip, and this tuna melt wrap.

WHY THIS RECIPE WORKS
- FAST & EASY! Seriously, this one of my go-to trusted recipes to whip up for a last minutes dinner or a quick lunch. It's full of flavor and nutritious with minimal ingredients that you already have in your fridge.
- HEALTHY. Sardines are high in Omega-3s, and with the added veggies you're getting a nutritious, and super simple sandwich. Win win!
- FLAVORS WORK WELL TOGETHER. The best condiment pairing for canned sardines is.... hot sauce, from personal experience. They're a popular go-to snack in my household and we're found a good hot sauce gives them added flavor and a little kick that pairs well. So, it was a natural condiment to use in this sandwich.
- CRUNCHY! The toasted bread is a must, but also adding sliced cucumber compliments the fish by creating a fresh and crunchy element.
RECIPE INGREDIENTS
- BREAD. Preferably sourdough because that's a go-to in our household to provide added flavor. Any other artisan or sliced bread will work, so go with your favorite. Make sure you have butter or oil on hand to toast the bread.
- CANNED SARDINES. Preferably, use a tin that's packed in oil. They provide a more rich and smooth taste, and added flavor to the sandwich.
- VEGGIES. You'll need sliced cucumber, sliced tomatoes, and diced green onions that's sprinkled on top for added flavor and of course, a little pop of color.
- CONDIMENTS. You'll need mayo, and sriracha, or another hot sauce of your choice. The sauce is slightly spicy, not too overboard and creates the perfect flavor balance between the fresh veggies and the flavor-rich sardines.

HOW TO MAKE A SARDINE SANDWICH
First, you'll want to toast the bread. Slather salted butter, and toast to your liking.
While the bread is toasting, let's whip up the spicy mayo sauce. In a small bowl, add the mayo and hot sauce, I like to use sriracha. Mix until well combined.
Slice cucumbers thinly, and the beef steak tomatoes. Open the tin of sardines and drain excess oil.
To the toast, add a good slather of sauce, then top with cucumber, then tomato slices. Using a fork, carefully scoop the sardines from the tin and top them to the sandwich. Sprinkle diced green onions to top.
Top with a squeeze of lemon or hot sauce, is optional.
If you prefer to close the sandwich, then top with another piece of toast with sauce on it.

FAQ
Canned sardines can be eaten as much as a couple times each week. Though, the exact amount will depend on your health conditions, and dietary restrictions. They often pack a high level of sodium to be aware of. They're also highly nutritious and can provide omega-3 fatty acids, protein, and essential vitamins and minerals.
