This is the dinner I pull out when I want something that looks carefully plated but takes less time than ordering takeout. Warm seasoned sushi rice forms the base, then cool cucumber, creamy avocado, and spicy shrimp get layered on top with a zigzag of sriracha mayo. It is fresh, a little fiery, and built from ingredients I almost always have.
The idea is simple. You are basically building a deconstructed California roll in vertical layers. A ring mold or even a measuring cup gives you those clean restaurant-style edges, but the real secret is seasoning the rice while it is still warm so every layer has flavor.
What you need for each layer
Quality matters here because the ingredient list is short. Use the best shrimp you can find, a ripe avocado that yields gently, and an English cucumber for its thin skin and small seeds.
- Large shrimp. Peeled and deveined so they cook evenly and eat cleanly. They sear in minutes and stay juicy if you pull them early.
- Sushi rice. Short-grain Japanese rice holds together when packed and carries the seasoned vinegar beautifully.
- English cucumber. Thin skin and minimal seeds mean no peeling or salting required. It adds the cool crunch that balances the heat.
- Ripe avocado. Creamy and mild, it bridges the gap between the warm rice and the spicy shrimp.
- Mayonnaise and sriracha. The spicy mayo ties everything together with a tangy, fiery finish.
- Sesame seeds and furikake. Toasted sesame adds nuttiness, and furikake brings umami and a little seaweed savor.
How to build the stacks
- Season and sear the shrimp. Toss the shrimp with olive oil, garlic powder, paprika, cayenne, salt, and pepper. Sear in a hot skillet for one to two minutes per side until just pink and opaque, then remove them so they do not overcook.
- Mix the spicy mayo. Whisk mayonnaise, sriracha, and lime juice until smooth. Taste and add more sriracha if you want extra heat.
- Season the rice. While the rice is still warm, fold in rice vinegar, sugar, and salt. The warmth helps the grains absorb the seasoning.
- Form the rice bases. Pack a layer of seasoned rice into a ring mold or a one-cup measure set on a plate. Press gently so it holds together when you lift the mold.
- Layer and finish. Top the rice with cucumber rounds, avocado slices, and the seared shrimp. Drizzle with spicy mayo, then sprinkle with sesame seeds, furikake, and sliced green onion.
Getting the rice texture right
The rice should be sticky enough to hold its shape but not gummy. If you are cooking it from scratch, rinse the grains under cold water until the water runs mostly clear. This removes excess starch that can make the rice too heavy. Fold in the vinegar mixture with a cutting motion rather than stirring so the grains stay distinct. Warm rice packs more cleanly than cold rice, which tends to crumble when pressed.
The mold trick for clean layers
You do not need a specialty ring mold. A one-cup dry measure, a wide biscuit cutter, or even a clean soup can with both ends cut out works. Oil the inside lightly so the rice releases cleanly. Pack the rice in firmly but not so tight that it becomes dense. Slide the mold up slowly and the rice cylinder should stand on its own. If it slumps, the rice needs a little more pressing or a touch more vinegar to help it bind.
Swaps when you are out
No sushi rice? Short-grain white rice works in a pinch, though it will be slightly less sticky. You can also swap the shrimp for cooked crab meat or even smoked salmon if you want a different protein. For a handheld version without the mold, try our spicy shrimp cucumber boats. If you prefer a bowl, our easy shrimp poke bowl is a good match. And for another stacked rice dinner, the garlic butter shrimp rice stack is hard to beat.
Make ahead and serve later
You can cook the rice and shrimp a few hours ahead and keep them refrigerated separately. Slice the cucumber and whisk the mayo early too. The only thing to do at the last minute is slice the avocado and assemble, since avocado browns quickly once cut. If you must prep it fully ahead, press plastic wrap directly against the cut avocado and assemble within an hour for the cleanest look.
What to pour on the side
A cold Japanese lager or a crisp sparkling water with lime cuts through the spice and richness. For a non-alcoholic option, try an iced green tea. A light salad like our easy California roll salad is a smart side if you want extra vegetables without doubling down on rice. The FDA recommends cooking shrimp to an internal temperature of 145°F; you can read more in their seafood safety guide.
FAQs
- Can I use frozen shrimp for this stack?
Yes. Thaw them under cold running water for about five minutes, then pat very dry with paper towels. Dry shrimp sear instead of steam, which gives you better color and flavor.
- What can I use if I do not have a ring mold?
A one-cup dry measure, a wide biscuit cutter, or a clean soup can with both ends removed all work. Oil the inside lightly so the rice releases without sticking.
- How do I make this gluten-free?
The base recipe is naturally gluten-free as long as your furikake and any soy-based sauces are certified gluten-free. Swap standard furikake for a gluten-free brand and use tamari if you add any extra sauce.
- Can I prepare any part ahead of time?
Cook the rice and shrimp up to a day ahead and refrigerate them separately. You can also mix the spicy mayo and slice the cucumber early. Wait to cut the avocado until just before assembling.
- Which rice works best?
Short-grain Japanese sushi rice is ideal because it is sticky and holds a shape. Short-grain white rice is the closest substitute, but avoid long-grain varieties like basmati or jasmine because they fall apart when pressed.
- How do I keep the avocado from turning brown?
Slice it right before serving, or toss the slices gently in a little extra lime juice. Pressing plastic wrap directly against the cut surface also slows browning for an hour or two.
- Can I tone down the spice?
Absolutely. Start with half a teaspoon of sriracha in the mayo and taste before adding more. You can also skip the cayenne in the shrimp seasoning and rely on mild paprika for color without heat.
