One-Pot Ratatouille

One-Pot Ratatouille is the easiest way to enjoy this classic French vegetable dish. You can serve this as a side, or make it the star of your meal by topping it with a protein. One of our favorite ways to serve ratatouille is at brunch, and I top it with an over easy egg. I like serving this for a brunch because it is easy to make a large portion of it, and you can serve it buffet style. Making it an easy prep, set up, and clean up too!

Another pro for making a one-pot Ratatouille is that you can get multiple veggies in at once! This will increase your variety and the number of servings of veggies you consume a day! One serving of cooked veggies is 1/2 cup, so if you have 1 cup of this ratatouille you get two servings of veggies in this meal.

This recipe includes eggplant, zucchini, squash, onion, and tomato. This is the classic combination for this French dish, but I personally love these veggies together because they offer different colors. Different colored fruits and vegetables are associated with having different vitamins and minerals. So, having a lot of different colors on your plate, a.k.a. “eating the rainbow”, is a great strategy for getting your essential nutrients. Other mixed dishes, like our Fiesta Rice also uses a combination of different colored produce!
