Gluten-Free Teriyaki Salmon

The smell of caramelizing tamari and maple syrup hitting a hot pan is enough to make anyone abandon their evening plans and stay for dinner. My neighbor actually knocked on my door one Tuesday night asking what was cooking because the aroma had drifted down the hallway. That is the power of a good teriyaki glaze.

I started making this on nights when my energy was low but I still wanted something that felt intentional. There is something deeply satisfying about watching that sauce transform from a thin liquid into something thick and coat the back of a spoon.

Ingredients

• 4 salmon fillets, skin on, about 170 g each: Skin on fillets hold together beautifully during baking and the skin acts as a natural barrier against the hot pan.
• 60 ml tamari or gluten free soy sauce: Tamari delivers a cleaner, deeper umami flavor than regular soy sauce and keeps this entirely gluten free.
• 2 tbsp pure maple syrup: This is your secret to a glaze that caramelizes without burning, unlike refined sugar which can turn bitter quickly.
• 2 tbsp rice vinegar: A gentle acidity that brightens the whole dish and cuts through the richness of the salmon.
• 1 tbsp sesame oil: Just a small amount lends an unmistakable toasty depth that ties everything to its Asian inspired roots.
• 2 garlic cloves, minced: Fresh garlic only, the jarred version lacks the sharp bite that makes this sauce sing.
• 2 tsp fresh ginger, grated: Grate it finely so it melts into the sauce rather than leaving chewy chunks behind.
• 2 tsp cornstarch plus 2 tbsp water: This simple slurry is what turns a thin liquid into a lacquered glaze that clings to every bite of fish.
• 1 tbsp sesame seeds: Mostly for visual appeal but they also add a faint crunch that makes each bite more interesting.
• 2 spring onions, sliced thin: Scatter these on at the very end for a fresh, mild onion bite and a pop of green color.

Instructions

Prepare your oven and pan:

Heat the oven to 200 degrees C (400 degrees F) and line a baking sheet with parchment paper so the salmon lifts off cleanly later.

Build the teriyaki sauce:

Whisk the tamari, maple syrup, rice vinegar, sesame oil, garlic, and ginger together in a small saucepan over medium heat until everything is blended and just beginning to steam.

Thicken the glaze:

Dissolve the cornstarch in water in a small bowl, then pour it into the saucepan while stirring constantly and cook for about 2 to 3 minutes until the sauce coats the back of a spoon.

Glaze the salmon:

Place the fillets skin side down on the prepared sheet and brush them generously with the warm sauce, saving a little extra for finishing.

Bake until perfectly done:

Slide the tray into the oven for 12 to 15 minutes until the fish flakes easily with a fork and the edges have turned a gorgeous deep amber.

Finish and serve:

Pull the salmon out, brush with any remaining sauce, and shower with sesame seeds and spring onions before bringing it to the table.

Save

The night my neighbor came over to ask about the smell, I ended up plating an extra fillet and we ate standing in the kitchen catching up on months of unspoken hello's.

What to Serve Alongside

Steamed jasmine rice is the obvious choice and it soaks up every drop of extra sauce like a sponge. A quick cucumber salad with rice vinegar and a pinch of sugar adds crunch and keeps the meal from feeling heavy.

Making It Your Own

A pinch of red pepper flakes stirred into the sauce gives the whole dish a low, warm heat that builds slowly with each bite. You could also swap the maple syrup for honey if that is what you have on hand, though the flavor will shift slightly toward floral rather than earthy.

Getting Ahead and Storing Leftovers

The sauce can be made up to three days in advance and kept in the refrigerator, which turns a weeknight dinner into something almost effortless.

• Leftover salmon keeps well for one day and is excellent cold on top of a lunchtime rice bowl.
• Reheat gently in a low oven to avoid cooking the fish further and drying it out.
• Always double check your tamari label to confirm it is certified gluten free before serving to anyone with a sensitivity.

Save

Some recipes become staples because they ask so little and give so much back. This is that kind of dinner.

Recipe FAQs

→ Can I use regular soy sauce instead of tamari?

Yes — regular soy sauce works for flavor, but tamari or a certified gluten-free soy sauce is needed to keep the dish gluten-free. Taste and adjust the maple syrup if soy is saltier.

→ How do I thicken the teriyaki glaze?

Dissolve cornstarch in cold water to make a slurry, stir it into the simmering sauce and cook 2–3 minutes until glossy and thickened. Add a little more slurry for a thicker coating.

→ Should I leave the skin on the salmon?

Leave the skin on to help the fillets hold together and to render extra flavor. Bake skin-side down and the flesh will flake easily while the skin crisps at the edges.

→ How can I add heat to the glaze?

Add a pinch of red pepper flakes to the sauce while simmering, or stir in a little gochujang or sriracha to the glaze for a deeper spicy-sweet profile.

→ Is it better to marinate the salmon?

Marinating for 20 minutes deepens flavor but is optional. If short on time, brushing the glaze before and after baking still yields a well-flavored finish.

→ How should leftovers be stored and reheated?

Cool quickly, refrigerate in an airtight container up to 2 days. Reheat gently in a low oven or briefly in a skillet to avoid drying the salmon; add reserved glaze if needed.
