Expert Tips for Instant Pot Ratatouille
- Prep Vegetables Uniformly: Cut all veggies into similar-sized pieces for even cooking and a perfectly tender texture throughout your Instant Pot Ratatouille.

- Use Fresh Herbs Wisely: Add hardy herbs like thyme before cooking and delicate basil at the end to preserve their vibrant flavors without overpowering the dish.
- Adjust Liquid Amounts: Too little liquid leads to burning, too much dilutes flavors; stick to the recommended amounts for a rich, balanced ratatouille.
