Sushi Cups Ingredients
For the Rice Base
• Sushi Rice – Rinse thoroughly before cooking to remove excess starch for perfect texture.
• Water – Ensure a proper ratio (1 cup rice to 1.5 cups water) for the best sushi rice results.
For the Filling
• Chopped Veggies (1/2 cup) – Select fresh options like carrots, cucumber, or bell peppers for a crunchy bite.
• Steamed Mukimame (1/4 cup) – A great source of plant-based protein; regular shelled edamame can be used instead.
• Diced Avocado (1/4 cup) – Choose ripe avocado for creamy texture and rich flavor.
• Sauce (1 tablespoon) – Options like soy sauce or coconut aminos can be used to enhance flavor based on dietary needs.
For the Spicy Mayo
• Mayonnaise (1/4 cup) – This is the base for creamy spicy mayo; vegan mayo is a suitable substitute for a dairy-free version.
• Sriracha Sauce (1 teaspoon) – Adjust the amount for desired heat level in the mayo.
• Honey (1 teaspoon) – Balances the spiciness; agave syrup can replace it for a vegan option.
• Sesame Oil (1/2 teaspoon) – Adds a rich, nutty flavor; optional for those avoiding oil.
For Garnish
• Black Sesame Seeds – Sprinkle for a pop of color and subtle crunch that enhances your sushi cups.

Step‑by‑Step Instructions for Sushi Cups
Step 1: Cook Rice
In a medium pot, combine 1 cup of rinsed sushi rice with 1.5 cups of water. Bring the mixture to a boil over medium-high heat, then reduce the heat to low, cover, and let it simmer for 20 minutes. After the rice is tender and the water has been absorbed, remove it from heat and allow it to cool slightly while keeping it covered.
Step 2: Form Rice Cups
Once the sushi rice has cooled slightly, prepare a muffin tin by lightly greasing it or using silicone muffin liners for easy removal. Press 2 heaping tablespoons of the cooled rice firmly into each muffin cup, compacting it well to maintain shape. Place the muffin tin in the refrigerator for about 20 minutes to help set the rice cups.
Step 3: Prepare Filling
While the rice cups chill, chop your chosen vegetables into small pieces, including ingredients like carrots, cucumber, and bell peppers. In a mixing bowl, combine 1/2 cup of these chopped veggies with 1/4 cup of steamed mukimame and 1/4 cup of diced avocado. Add your preferred sauce, such as soy sauce, and mix everything gently until evenly coated.
Step 4: Make Spicy Mayo
In a separate bowl, whisk together 1/4 cup of mayonnaise, 1 teaspoon of Sriracha sauce, 1 teaspoon of honey, and 1/2 teaspoon of sesame oil until the mixture is smooth and well-blended. Adjust the heat by adding more Sriracha as desired, making sure to create a balanced, creamy spicy mayo perfect for drizzling over your sushi cups.
Step 5: Assemble Cups
Take the chilled rice cups out of the refrigerator and carefully remove them from the muffin tin. Spoon a generous amount of the veggie filling over each sushi rice cup. Drizzle the prepared spicy mayo generously on top of the filling, then finish by sprinkling black sesame seeds for added crunch and visual appeal, showcasing your delightful sushi cups.

Storage Tips for Sushi Cups
Fridge: Store leftover sushi cups in an airtight container for up to 2 days to maintain freshness and prevent sogginess.
Freezer: If you want to keep them longer, freeze the rice cups without the filling or spicy mayo for up to 1 month. Assemble and enjoy fresh when ready!
Reheating: When ready to eat, thaw frozen cups in the fridge overnight, then microwave briefly to reheat. Avoid overcooking to keep the rice soft.
Serving: Enjoy these sushi cups cold or at room temperature for the best flavor experience—perfect for snacks on the go or light gatherings!
Make Ahead Options
These Sushi Cups are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the sushi rice and rice cups up to 24 hours in advance, pressing the cooled rice into a muffin tin and refrigerating them until you’re ready to serve. The veggie filling, made from your choice of chopped vegetables, mukimame, and avocado, can also be prepped up to 3 days ahead—simply store it in an airtight container to keep it fresh. When you’re ready to impress your guests or enjoy a quick snack, just assemble your sushi cups by adding the veggie filling and drizzling the spicy mayo on top. This way, you’ll have deliciously fresh Sushi Cups that taste just as delightful as if they were made on the spot!

Sushi Cups Recipe FAQs
How do I select the right vegetables for my sushi cups?
Absolutely! When choosing vegetables, fresh and crispy options like carrots, cucumber, bell peppers, or sprouts work beautifully. Look for vibrant colors and firm textures. Avoid any that show dark spots or appear wilted for the best results!
What is the best way to store leftover sushi cups?
To keep your leftover sushi cups fresh, store them in an airtight container in the refrigerator for up to 2 days. This prevents sogginess while maintaining the flavor. For longer storage, consider freezing the rice cups without fillings.
Can I freeze my sushi cups for later use?
Certainly! To freeze your sushi cups, assemble the rice base without the filling or spicy mayo first. Place them in a single layer on a baking sheet to freeze, then transfer to a zip-top freezer bag. These can be stored for up to 1 month. When ready to enjoy, thaw in the fridge overnight and fill with fresh ingredients.
What if my sushi rice turns out too sticky or gummy?
No worries! If your sushi rice is sticky, this often happens due to insufficient rinsing before cooking. Be sure to rinse the rice well under cold water until the water runs clear to remove excess starch. If it’s overcooked, try adding a dash of rice vinegar and tossing gently to fluff it up.
Are sushi cups suitable for people with food allergies?
Very! You can easily customize the ingredients to suit various dietary needs. For non-dairy options, substitute regular mayonnaise with vegan mayo, and ensure your sauces, like soy sauce, are gluten-free if needed. Always check labels for allergens if you’re serving to guests with specific dietary restrictions.
How long can I keep sushi cups in the refrigerator?
I often advise using your sushi cups within 2 days for optimal freshness. Their delightful crunch and flavor are best enjoyed soon after assembly. If you need them for an event, feel free to make the rice cups in advance and assemble just before serving!
