🔑 Tips for Best Results
- Cut evenly. Dice vegetables into similar sizes so they cook evenly.
- Eggplant first. Salt diced eggplant for 15 minutes, then pat dry to remove bitterness.
- Keep it rustic. Don’t over-blend; this dish should have distinct chunks of veggies.
- For thicker stew. Remove lid for last 30 minutes to let liquid reduce.
- Next-day magic. Ratatouille tastes even better after resting overnight.
