I always start by heating my oven to 425°F and lining a baking sheet with parchment paper. This step takes two minutes but makes cleanup so much easier later. A properly hot oven is what gives the rice that shattering crunch.
I toss my cooled rice with sesame seeds, half the soy sauce, and half the chili oil in a bowl. Making sure every grain gets coated evenly is what helps the rice crisp up on all sides. I spread it in a thin, even layer on one side of my tray.
Next, I rub my salmon fillet with the remaining soy sauce and chili oil. I place it on the other half of the same tray so it roasts next to the rice. Keeping the seasoning simple here works because the dressing does the heavy lifting later.
I slide the tray into the oven and roast for 12 to 15 minutes. I like my salmon just barely cooked through, so I usually pull it around the 12-minute mark. The rice should look golden and slightly curled at the edges when it's ready.
While everything roasts, I whisk together soy sauce, rice wine vinegar, sesame oil, and olive oil in a small bowl. I stir in the garlic and ginger last so their flavor stays sharp. This dressing takes under two minutes and ties the whole bowl together.
Once the tray comes out, I flake the salmon into large chunks with a fork. I add the cucumbers, edamame, crispy rice, and salmon to a big mixing bowl. Then I top it with avocado slices, green onions, and cilantro before drizzling the dressing over everything.
I give everything one good toss so the dressing coats every piece. I like serving this immediately while the rice is still crackly. It also holds up well if you want to portion it for later.
