Vegan Unagi Don Ingredients
For the Grilled Eggplant
- 2 medium eggplants (sliced lengthwise) – These will provide a meaty texture that mimics traditional unagi.
- 1/4 cup soy sauce (or tamari for gluten-free) – This adds a savory umami flavor that enhances the dish’s richness.
- 2 tablespoons maple syrup – A touch of sweetness that balances the saltiness of the soy sauce beautifully.
- 1 tablespoon rice vinegar – This brings a subtle tang that brightens up the overall flavor profile.
- 1 teaspoon sesame oil – Adds a nutty aroma and depth, making your Vegan Unagi Don truly special.
- 1 teaspoon grated ginger – Fresh ginger contributes a zesty kick that complements the grilled eggplant perfectly.
- 1 teaspoon garlic powder – A hint of garlic enhances the savory notes without overpowering the dish.
For the Rice
- 2 cups jasmine rice (or sushi rice) – Opt for jasmine for its fragrant aroma or sushi rice for stickiness, perfect for pairing with eggplant.
- 4 cups water – Essential for cooking the rice to fluffy perfection.
For Garnish
- 2 tablespoons chopped green onions – Adds a fresh and vibrant crunch to each bite of your Vegan Unagi Don.
- 1 tablespoon sesame seeds (toasted) – Toasted seeds lend a delightful crunch and nutty flavor that elevates this dish.
How to Make Vegan Unagi Don
1. Rinse the rice: Rinse the jasmine rice under cold water until the water runs clear. This step removes excess starch, ensuring fluffy rice. Combine the rinsed rice and 4 cups water in a rice cooker and cook according to the manufacturer’s instructions.
2. Prepare the marinade: In a mixing bowl, whisk together 1/4 cup soy sauce (or tamari for gluten-free), 2 tablespoons maple syrup, 1 tablespoon rice vinegar, 1 teaspoon sesame oil, 1 teaspoon grated ginger, and 1 teaspoon garlic powder. This flavorful mix will infuse your eggplant with deliciousness!
3. Marinate the eggplant: Add the sliced lengthwise eggplants to the marinade and let them soak for at least 15 minutes. The longer they sit, the more flavor they’ll absorb—perfect for making your Vegan Unagi Don irresistible.
4. Preheat the grill: While the eggplant is marinating, preheat your grill to medium-high heat. A hot grill will give those eggplants a beautiful char and enhance their flavor.
5. Grill the eggplant: Grill the marinated eggplant slices for about 5-7 minutes on each side, or until they are tender and slightly charred. You want those lovely grill marks to add that smoky taste!
6. Assemble the dish: Serve the grilled eggplant over a bed of fluffy cooked jasmine rice. Garnish with 2 tablespoons chopped green onions and 1 tablespoon toasted sesame seeds for an extra touch of flavor and color.
Optional: Drizzle with extra sesame oil for added richness.

Tips for the Best Vegan Unagi Don
- Eggplant Selection: Choose firm, medium-sized eggplants for grilling. Overripe eggplants can become mushy and lose their texture.
- Marination Time: Allow the eggplant to marinate for at least 15 minutes, but longer is better. This enhances flavor absorption.
- Grill Temperature: Ensure your grill is preheated to medium-high. Cooking on a too-low heat can lead to soggy eggplant instead of a nice char.
- Rice Rinsing: Always rinse your jasmine rice until the water runs clear. This removes excess starch and prevents clumpy rice—key for a perfect Vegan Unagi Don.
- Garnish Wisely: Toasted sesame seeds add depth! If you skip this step, you might miss out on that essential nutty flavor.
How to Store and Freeze Vegan Unagi Don

- Fridge: Store leftover Vegan Unagi Don in an airtight container for up to 3 days. This keeps the eggplant tender and flavorful.
- Freezer: For long-term storage, freeze the grilled eggplant separately from the rice in airtight containers for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheating: To reheat, microwave the rice and eggplant separately until hot or warm them in a skillet over medium heat for about 5 minutes, adding a splash of water if needed.
- Garnish: Add fresh green onions and toasted sesame seeds just before serving to maintain their crunch and flavor!
Vegan Unagi Don Your Way
Feel free to get creative and make this dish uniquely yours with these delightful twists!
- Smoky Flavor: Add 1 teaspoon of smoked paprika to the marinade for a deeper, more complex flavor. This brings a lovely richness that enhances the grilled taste of the eggplant.
- Sweetness Boost: Substitute agave syrup for maple syrup for a different sweetness profile. This change adds a delightful floral note that pairs beautifully with the savory elements.
- Spicy Kick: Mix in 1 teaspoon of chili flakes or Sriracha to the marinade for some heat. This twist adds an exciting kick that balances perfectly with the sweet and savory flavors.
- Veggie Variety: Replace eggplant with zucchini or portobello mushrooms for a different texture and taste experience. Each vegetable offers its own unique flavor, making your bowl just as satisfying.
- Nutty Crunch: Top your dish with chopped peanuts or crushed cashews for added crunch. This will not only enhance the texture but also introduce a rich, nutty flavor that complements the other ingredients beautifully.
- Herb Infusion: Incorporate fresh basil or cilantro into your garnish for an aromatic touch. These herbs bring freshness and brightness, elevating each bite to a new level of deliciousness.
- Coconut Rice: Cook your rice in coconut milk instead of water for a creamy twist. The subtle sweetness of coconut adds an indulgent layer that pairs wonderfully with the marinated eggplant.

Vegan Unagi Don Recipe FAQs
What type of eggplant is best for this Vegan Unagi Don?
For this recipe, medium-sized globe eggplants work perfectly. Their meaty texture holds up well during grilling and absorbs the marinade beautifully. If you prefer a slightly sweeter flavor, you can also experiment with Japanese eggplants, which tend to be thinner and have a more delicate taste.
How long should I marinate the eggplant?
Marinating the sliced eggplant for at least 15 minutes allows it to soak up all the flavorful ingredients like soy sauce, maple syrup, and ginger. However, if you want an even deeper flavor, feel free to marinate for up to 30 minutes in the refrigerator. Just remember to keep an eye on it so it doesn’t get too soft!
Can I make this recipe gluten-free?
Absolutely! Simply swap out regular soy sauce for tamari, which is a gluten-free alternative. This will ensure that your Vegan Unagi Don remains gluten-free while still delivering that rich umami flavor we all love.
What’s the best way to store leftovers?
Store any leftover grilled eggplant and rice in separate airtight containers in the fridge. They will stay fresh for about 3-4 days. When you’re ready to enjoy them again, just reheat in the microwave or on the stove until warmed through—about 2-3 minutes should do!
Can I freeze the grilled eggplant?
Yes! Grilled eggplant can be frozen for up to 2 months. For best results, allow it to cool completely before placing it in freezer-safe bags or containers. When you’re ready to eat, simply thaw in the fridge overnight and reheat on the grill or stovetop until heated through.
