Instructions

  1. Step 1: Preheat the oven to 425°F. Slice 1 medium eggplant into 1/2-inch rounds, brush both sides with 1 tbsp olive oil, and roast on a baking sheet for 20 minutes until tender and golden.
  2. Step 2: While the eggplant roasts, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 4 cups fresh spinach and sauté for 2-3 minutes until wilted but still bright green.
  3. Step 3: In a small bowl, whisk together 3 tbsp white miso paste, 1 tbsp soy sauce, and 1 tbsp mirin until smooth.
  4. Step 4: To assemble, divide 3 cups cooked short-grain rice into bowls, top with roasted eggplant slices and sautéed spinach. Drizzle the miso glaze evenly over the top.
  5. Step 5: Garnish each bowl with 1 tsp sesame seeds and 1 sliced green onion for a nutty crunch and fresh finish.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep eggplant from drying out.

Can I substitute ingredients in Roasted Eggplant and Spinach Miso Donburi?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Roasted Eggplant and Spinach Miso Donburi for a different number of people?

The recipe is written for 3 servings. Multiply each ingredient by (your serving target / 3). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
