Miso Eggplant Onigiri Ingredients

For the Onigiri
• Sushi Rice – The foundation of onigiri; rinse thoroughly before cooking to achieve a perfect sticky texture.
• Water – Crucial for cooking the sushi rice to the right consistency.

For the Filling
• Olive Oil – Adds moisture and richness while sautéing the filling ingredients.
• Scallions (2) – Bring a layer of freshness; substitute with chives if desired.
• Red Onion (1/4 cup, finely chopped) – Enhances sweetness; can also use shallots for a different profile.
• Chinese or Japanese Eggplant (1) – The star of the filling; cut into 1” cubes, with zucchini as an alternative if needed.
• Miso (1 tbsp) – Introduces deep umami flavor, critical for the savory aspect of these Miso Eggplant Onigiri.
• Sugar (1 tbsp) – Balances the savory notes of miso for a harmonious filling.
• Salt (1/4 tsp) – Elevates the overall flavor of the mixture.
• White Pepper (1/2 tsp) – Adds a subtle spice to the filling.
• Dark Soy Sauce (1/4 cup) – Provides rich depth; regular soy sauce works for a lighter taste.

For Wrapping

How to Make Miso Eggplant Onigiri

Cook Rice: Rinse the sushi rice under cold water until the water runs clear, then combine it with water in a rice cooker. Cook according to the manufacturer’s instructions until tender and sticky.
Prepare Filling: In a pan, heat the olive oil over medium heat. Sauté the chopped scallions and red onion until they soften, about 5 minutes. Increase the heat, then add the eggplant. Cook for another 5 minutes until it starts to soften.
Season Filling: Sprinkle in the miso, sugar, salt, and white pepper. Stir well to combine, then add dark soy sauce and a splash of water. Cook until the eggplant is tender and the mixture has thickened, about 10 minutes. Set aside to cool.
Form Onigiri: When the rice is cooked, let it cool for 5-10 minutes while still warm. Lay out a piece of plastic wrap on a flat surface and wet your hands. Place a handful of rice on the wrap, flatten it slightly, and add a spoonful of the cooled eggplant filling. Top with more rice, gather the wrap edges, and shape into a triangle or ball. Unwrap and place in a sheet of nori.
Serve: Enjoy your Miso Eggplant Onigiri fresh or store them in an airtight container for later.

Optional: Serve with pickled vegetables for an added crunch.

Make Ahead Options

These Miso Eggplant Onigiri are perfect for meal prep enthusiasts looking to save time during the busy week! You can prepare the eggplant filling up to 3 days in advance; simply cool it completely and store it in an airtight container in the refrigerator. The sushi rice can also be cooked up to 24 hours ahead; allow it to cool and keep it covered with a damp cloth to prevent it from drying out. When you’re ready to assemble, just warm the rice slightly if needed, then shape the onigiri with the chilled filling. Wrapping them in nori just before serving ensures they remain crispy and fresh, giving you restaurant-quality results with minimal effort!

Expert Tips for Miso Eggplant Onigiri

Rice Texture: Ensure your sushi rice is warm when forming the onigiri; it helps bind the rice together, preventing it from falling apart.
Avoid Sticking: Use wet hands when handling the rice to avoid it sticking to your fingers. This will make shaping the onigiri a lot smoother!
Filling Consistency: Don’t skip cooling the eggplant filling before shaping. Hot filling can cause the rice to turn mushy and lose its shape.
Nori Timing: Wrap your onigiri in roasted nori just before serving to maintain its crisp texture. Otherwise, it can become chewy.
Substitutions: Feel free to explore different fillings beyond miso eggplant! Options like avocado or teriyaki tofu can give your Miso Eggplant Onigiri a delightful twist.

How to Store and Freeze Miso Eggplant Onigiri

Fridge: Store leftover onigiri in an airtight container for up to 3 days. To maintain freshness, wrap each piece individually in plastic wrap before placing in the container.

Freezer: For longer storage, freeze onigiri individually wrapped in plastic for up to 2 months. Thaw in the fridge overnight before reheating.

Reheating: To revive texture, reheat in the microwave with a damp paper towel for about 30 seconds. This helps restore moisture without making them soggy.

Freshness Tip: Enjoy the Miso Eggplant Onigiri fresh whenever possible, and wrap them in nori just before serving to keep that delightful crispness!

Miso Eggplant Onigiri Recipe FAQs

What type of eggplant should I use for the filling?
Absolutely! I recommend using Chinese or Japanese eggplant for the best flavor and texture in your Miso Eggplant Onigiri. They have a tender skin and a sweeter flavor. If you can’t find these, zucchini works as a suitable alternative, though the taste will differ slightly.

How should I store leftover onigiri?
Leftover onigiri can be stored in an airtight container in the refrigerator for up to 3 days. To keep them fresh, wrap each onigiri individually in plastic wrap before placing them in the container. This prevents the rice from drying out!

Can I freeze Miso Eggplant Onigiri?
Yes, you can freeze Miso Eggplant Onigiri! Wrap each onigiri in plastic wrap and place them in a zip-top freezer bag or airtight container. They can be frozen for up to 2 months. To enjoy them, thaw them overnight in the refrigerator, then reheat gently in the microwave with a damp paper towel to restore moisture (about 30 seconds should do!).

What if my rice doesn’t stick together?
Very! If your rice isn’t sticking together well, it might be due to using cold rice. Ensure you form your onigiri while the rice is still warm. This helps the grains bind together better. Additionally, wet your hands before handling the rice to reduce sticking, which makes shaping easier.

Are there any dietary considerations for these onigiri?
Absolutely! These Miso Eggplant Onigiri are vegan and vegetarian-friendly. However, check the miso paste for any added ingredients, as some brands may contain fish products. Always opt for a miso labeled gluten-free if you have gluten sensitivity. Enjoy them as a delicious, plant-based snack!
