Ingredients

Instructions

  1. Step 1: Heat avocado oil in a medium skillet over medium heat. Add onions and cook for 12-15 minutes, stirring occasionally, until deeply caramelized and golden brown.
  2. Step 2: Stir in minced garlic and cook for 1 minute until fragrant. Add coconut aminos, lemon juice, and sea salt, then bring to a gentle simmer.
  3. Step 3: Arrange eggplant slices on top of the onion mixture, pressing gently to submerge. Reduce heat to low, cover, and simmer for 10 minutes until eggplant is tender.
  4. Step 4: Remove lid, increase heat to medium, and cook uncovered for 3 minutes to thicken the sauce slightly. Serve hot with extra lemon wedges.

How do I store leftover Poached Eggplant with Caramelized Onions and Lemon?

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 medium, thinly sliced onions from drying out.

Can I substitute ingredients in Poached Eggplant with Caramelized Onions and Lemon?

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 Poached Eggplant with Caramelized Onions and Lemon for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). 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.
