Step-by-Step Instructions
Step 1: Make the Teriyaki Marinade
In a small bowl, whisk together the soy sauce, mirin, brown sugar, rice vinegar, sesame oil, minced garlic, grated ginger, and a pinch of black pepper until the sugar has mostly dissolved. Taste the mixture; it should be salty-sweet with a little tang. If you want it sweeter, add an extra 1/2 teaspoon of brown sugar; for more tang, add a splash more rice vinegar.
Pour out 2 tablespoons of this marinade into a very small saucepan or heatproof bowl and set aside. This portion will be cooked later to become your glossy teriyaki glaze for drizzling over the finished salmon.
Step 2: Marinate the Salmon
Place the salmon fillets in a shallow dish or resealable bag. Pour the remaining marinade (not the reserved 2 tablespoons) over the salmon, making sure the fillets are well coated on all sides. If using a dish, spoon marinade over the top so every surface gets contact.
Let the salmon marinate for at least 10–15 minutes at room temperature while you prepare the toppings. If you want a stronger flavor and have time, you can refrigerate and marinate for up to 30 minutes, but avoid going much longer so the fish does not become overly salty.
Step 3: Prep the Toppings
While the salmon marinates, prepare the toppings so assembly is quick later. Wash the cucumber and pat dry. Using a vegetable peeler or mandoline, shave the cucumber lengthwise into thin ribbons, rotating the cucumber as you go until you reach the seed core. If you prefer, you can slice it into very thin rounds instead. Set aside on a plate and lightly sprinkle with a tiny pinch of salt to keep it crisp and flavorful.
Thinly slice the scallions on a slight diagonal to create pretty, delicate strips. If using fresh herbs like shiso or cilantro, roughly chop or chiffonade them. In a small bowl, stir together the mayonnaise and wasabi paste (or sriracha), adjusting the heat level to your taste. Set all the toppings aside, ready to use.
Step 4: Cook the Salmon
Preheat your oven to 400°F (200°C). Lightly grease a small baking dish with the neutral oil, or line it with parchment paper for easy cleanup. Remove the salmon from the marinade, letting excess drip off, and place the fillets in the prepared dish. Discard any leftover marinade from the dish or bag that touched raw fish.
Bake the salmon on the middle rack for 10–12 minutes, depending on thickness, until the fish flakes easily with a fork and is just opaque in the center. A thermometer inserted into the thickest part should read about 125–130°F (52–54°C) for moist, medium doneness. Avoid overcooking; you want the salmon juicy so it flakes nicely onto the bagel.
While the salmon bakes, bring the reserved 2 tablespoons of marinade to a simmer in the small saucepan over medium-low heat. Let it bubble gently for 2–3 minutes, stirring often, until slightly thickened and glossy. Remove from heat; it will thicken a bit more as it cools.
Step 5: Toast the Bagels
While the salmon finishes cooking, toast the onion bagel halves to your preferred level of crispness. A medium toast works well here: enough structure to hold the toppings, but still soft enough to bite through easily. If you like, you can warm them in the oven on a baking sheet for 3–4 minutes instead of using a toaster, which gently heats the onion flavor.
Spread a thin to generous layer of the wasabi mayonnaise (or plain mayo) over the cut sides of each toasted bagel half. If you prefer a richer, more traditional bagel feel, you can add a thin base layer of cream cheese under the mayo, but keep it light so it does not overwhelm the teriyaki flavor.
Step 6: Flake and Glaze the Salmon
Once the salmon is done, remove the baking dish from the oven and let it rest for 2–3 minutes so the juices redistribute. Using a fork, gently flake the salmon into large, bite-sized pieces. Keep the flakes fairly chunky so you get big, satisfying bites on the bagel.
Drizzle the warm, thickened teriyaki glaze over the salmon flakes and very gently toss to coat, being careful not to break the pieces down too much. You should see a shiny, caramelized sheen on the fish. Taste a piece and, if desired, season with a tiny pinch of extra salt or a squeeze of lime or lemon juice to brighten the flavors.
Step 7: Assemble the Teriyaki Salmon Bagels
On the bottom halves of each mayo-coated bagel, arrange a generous layer of cucumber ribbons, letting them fold and curl for height and texture. Season the cucumber lightly with a pinch of black pepper.
Top the cucumber with a generous mound of glazed salmon flakes, dividing evenly between the two bagels. Sprinkle each with plenty of sliced scallions and toasted sesame seeds. If you are using nori strips or fresh herbs, scatter a few on top for color and a subtle seaweed or herbal aroma.
Cap each with the top half of the onion bagel (or leave open-faced if you prefer a knife-and-fork experience). Press gently to help everything settle, and serve immediately while the bagel is warm and the salmon is still slightly steamy and glossy.
Pro Tips
- Do not over-marinate the salmon. Because the marinade is salty, 15–30 minutes is plenty. Longer can start to firm the fish too much and make it too salty.
- Control the cook time based on thickness. Thinner fillets may be fully cooked in 8–9 minutes; thicker ones can take up to 12–13 minutes. Start checking early.
- Toast sesame seeds fresh if possible. A quick 2–3 minutes in a dry skillet over medium heat until fragrant makes a big difference in flavor.
- Assemble just before serving. The cucumber and bagel stay crispest if you construct the sandwiches right before eating, rather than letting them sit.
- Use good bagels. A flavorful, slightly chewy onion bagel is the backbone of this recipe. If the bagels are very large, you can stretch the salmon to make 3 smaller, open-faced portions.
Variations
- Spicy Teriyaki Salmon Bagel: Add extra wasabi or sriracha to the mayo, and drizzle a little chili crisp over the salmon flakes before adding the scallions and sesame seeds.
- Creamier Brunch-Style Bagel: Spread a thin layer of cream cheese under the mayo, and add thin slices of avocado with the cucumber ribbons for extra richness.
- Pan-Seared Instead of Baked: Marinate as directed, then sear salmon in a lightly oiled nonstick skillet over medium-high heat, 3–4 minutes per side, until caramelized and cooked through. Finish with the thickened glaze.
Storage & Make-Ahead
This recipe is best enjoyed freshly assembled, but you can break the work into parts:
You can marinate the salmon for up to 30 minutes ahead in the refrigerator, then cook just before serving. The teriyaki glaze (the reserved and cooked-down marinade) can be made up to 2 days in advance; store it in a sealed container in the fridge and rewarm gently before using. Sliced scallions and prepared cucumber ribbons can be stored separately in airtight containers in the refrigerator for up to 1 day; pat the cucumber dry before assembling to avoid sogginess.
If you have leftover cooked teriyaki salmon, cool it completely, then store in an airtight container in the fridge for up to 2 days. Reheat gently in a low oven (300°F / 150°C) or enjoy cold, flaked over a fresh bagel. Once assembled, the bagel will soften and is best eaten within 30–40 minutes.
