Ingredients Overview

Each layer of this sushi bake contributes to its savory, spicy, creamy character. Here’s what you’ll need and how to adjust it to your taste or dietary needs.

Salmon

Salmon is the star of this recipe — rich, flaky, and full of healthy omega-3 fats.

• Use cooked salmon (baked, broiled, or leftover)

• Canned wild salmon also works well (just drain thoroughly)

• Fresh or frozen fillets: bake with salt and pepper at 400°F for 12–15 minutes, then flake

Substitutions:

• Cooked tuna (fresh or canned)

• Cooked shrimp or imitation crab for a California-style bake

• Firm tofu (for a vegetarian option)

Cooked Rice

Short-grain or medium-grain rice is best for a sticky base that mimics sushi.

• Use sushi rice or short-grain white rice

• Season with a mix of:

  • 2 tbsp rice vinegar

  • 1 tbsp sugar

  • 1 tsp salt

Tips:

• Use day-old rice or let fresh rice cool slightly before layering

• For a low-carb version, use cauliflower rice (well-drained)

Creamy Spicy Sauce

The spicy mayo-style mixture binds the salmon and adds signature heat and richness.

Base ingredients:

• ⅓ cup Japanese mayo (like Kewpie) or regular mayo

• 1½–2 tbsp sriracha (adjust to heat preference)

• 1 tsp sesame oil (optional for nutty depth)

• Optional: 1 tsp soy sauce or 1 tsp lemon juice for brightness

Optional Add-Ins & Toppings

Make your sushi bake shine with extras:

• Cream cheese (for extra creaminess — 2 oz, softened and mixed into the salmon)

• Chopped green onions or chives

• Furikake (Japanese rice seasoning with seaweed and sesame seeds)

• Avocado slices (added after baking)

• Pickled ginger or cucumber ribbons (for serving)

Nori Sheets (Roasted Seaweed)

To serve, scoop up the warm sushi bake onto small squares of nori for a hand-held sushi bite. Think of them as savory seaweed “tacos.”

Tips, Variations & Substitutions

Cooking Tips

• Don’t overbake: You want the salmon topping creamy and the rice just warmed.

• Tuna Melt Bake: Use canned tuna, cheddar, and scallions.

• Vegetarian: Sub in seasoned tofu and diced veggies like cucumber or carrot.

Dietary Swaps
