Hailing from Provence, a sunny region in the south of France near the Mediterranean Sea, ratatouille is a vibrant summer vegetable stew. This dish features eggplant, zucchini, bell peppers, and tomatoes, all richly seasoned with olive oil, garlic, and fresh herbs. It takes some time to prepare, so making a large batch over the weekend is ideal. This way, you’ll have a tasty and colorful base ready for meals throughout the week.

Ratatouille is incredibly versatile. Serve it as a vegetarian main with grains or creamy polenta, alongside Italian sausage, grilled steak or cedar planked salmon, or tuck it into omelets or frittatas. It’s also fantastic spooned over crostini with a smear of goat cheese or even enjoyed cold from the fridge as a healthy snack.

“What a great way to use the summer harvest. Enjoyed it with a little goat cheese on top. My husband loved it too – this is a keeper!”

What You’ll Need To Make Ratatouille

Ratatouille ingredients including tomato paste, zucchini, and bell pepper.
  • Extra Virgin Olive Oil: Used for sautéing the vegetables and adds flavor. A drizzle before serving really makes the dish shine.
  • Eggplant, Zucchini, Bell Pepper, and Tomatoes: These core vegetables provide a mix of textures and flavors—eggplant adds meatiness, zucchini offers a mildly sweet flavor and tender-crisp texture, bell peppers bring sweetness and crunch, and tomatoes contribute tartness and moisture, creating a saucy base.
  • Onion and Garlic: Essential aromatics that form a flavor foundation for the dish.
  • Tomato Paste: Intensifies the tomato flavor, adds depth in color, and helps thicken the stew.
  • Fresh Thyme and Basil: Thyme provides a subtle earthiness, while basil adds a fresh, sweet touch that really brightens up the dish.
  • Crushed Red Pepper Flakes (optional): Introduces a hint of heat, adjustable to taste preference.

Frequently Asked Questions

Can ratatouille be made ahead of time?

Absolutely! In fact, you should make ratatouille at least a day ahead of time if possible. Like most stews, the dish improves after the flavors have a chance to mingle in the refrigerator. Leftovers can be stored in the refrigerator in an airtight container for up to 5 days

Can ratatouille be frozen?

Yes, ratatouille freezes very well. Make sure to cool it completely before transferring it to airtight containers or freezer bags. It can be stored in the freezer for up to three months for a taste of summer once the cooler weather arrives. Before using, thaw it in the refrigerator overnight and then reheat gently to preserve the texture of the vegetables.

Why does each vegetable need to be cooked separately?

Cooking each vegetable separately before combining them in ratatouille ensures that each component cooks to the right texture and retains its distinct flavor. Different vegetables have varying cooking times; for instance, eggplants and peppers take longer to become tender compared to tomatoes and zucchini. By sautéing them individually, you can ensure they are all perfectly cooked.

  • Amazing…like most of the recipes I have tried from your site! Another winner! I will definitely be making this again!

  • Thank you very much, that was perfect, I have just used tomato passata instead tomato paste for a better result.

  • Excellent dish! As always, I appreciate the clear directions and love the finished product. Big hit in our house!

  • Super super delicious! Thanks a lot for the recipe. I’ve tried some other ratatouille recipes which all cost a lot more time but tasted much less amazing compared to this recipe! I followed the recipe exactly, very good idea to cook the vegetables in batches, so you don’t end up with a mushy mess. Served it over fluffy couscous with some creamy goat cheese sprinkled over it 10/10 vegetarian dish!

  • This is SUPER yummy!

    I made this a day and a half ago, and it really just gets better and better. I woke up in the middle of the night thinking about it and actually got up to eat a small bowl!

    The only small changes I made were adding a few teaspoons of Better Than Bouillon Chicken Base, and not using basil as we didn’t have any. It’s hard to believe this could be any tastier, but I imagine it will be with basil next time around.

    We will definitely be making this on a regular basis. Thank you, Jenn!

  • I’ve been making ratatouille since the 70’s! It was quite the exotic dish back then. My original recipe called for cooking all the vegetables separately, like this one. But over the years I started just throwing the veggies together, and thought that I had become “tired” of this dish. Au contraire! THIS is the way to make ratatouille. My only changes to the recipe were 1/2 as much eggplant (mine was small); only a pinch of dried thyme, 1/4 C each of chopped fresh basil and parsley added to the tomato mixture; and no tomato paste (none in the cupboard). And, the veggies I used were mostly approaching over-the-hill. And still, this was delicious! Served it along grilled, crispy chicken thighs, with multiple berry shortcake for dessert. Yum! This will be my go-to recipe and process from now on. Thank you, Jenn!

  • This recipe produces a lovely, chunky, flavorful dinner. I modified it a bit but found the basil and thyme proportions to be spot on. We served it with air-fryer gnocchi. Thank you for developing and posting this recipe! Happy cooking!

    • Your recipes are always perfect. Ratatouille is so delicious. Being from France originally I can say it’s the real thing. Not only I get your books but I write down all your recipes and follow them faithfully. They never fail. Thank you so much. I could bookmark on my IPad but I enjoy writing down your recipes in my book and going thru it often to find out what to cook the next day.

      • So good- used up a bunch of fresh vegetables, easy to make as all your recipes are

  • Another amazing recipe!! We are never disappointed with any recipe we’ve made from Once Upon a Chef. Thank you.

    • This is my absolute favorite recipe for ratatouille!

  • Yummy! First time I have tried making ratatouille, and this was amazing! Scrumptious! I did add some fresh basil to it and omitted the sugar, and the family loved every bit of it!

  • I first went to Julia Child as my source for making traditional ratatouille. Then, having made many successful recipes from Jenn, I decided to check here also to compare. So glad I did, as Jenn’s appeared to be simpler and included the addition of fresh herbs. I fresh, farm market veggies (except for the eggplant ) as well as our own fresh thyme and basil. To speed up the process, I used multiple skillets at the same time and then combined them at the end in a large dutch oven on the range top. It was a bit more pan washing for the sous chef (husband) but I liked the increased speed. It was delicious- we served as is, but offered with parmesan cheese optional. Family loved it and I will make again soon. Can’t wait to try it today per the suggestion that it is better made a day ahead. Thanks again Jenn for another terrific recipe 😀
