Notes

Storage

Store leftovers in a sealed container in the refrigerator for up to 5 days.

Make Ahead

You can make ratatouille ahead of time. In fact, it tastes even better the next day as the flavors have had a chance to meld together. Simply reheat on the stovetop or in the microwave.

Freezing

I recommend freezing it in individual servings so that you can thaw and reheat only as much as you need. Ratatouille will keep in the freezer for up to 3 months.

Reheating

Reheat on the stovetop over low heat or in the microwave. If reheating from frozen, you may need to add a little water or chicken broth to thin it out as it will thicken as it reheats.
