    I wanted to share this delicious ratatouille recipe that I recently made that has become a quick favorite. It’s loaded with lots of  fresh summer vegetables and makes an extremely flavorful and healthy side dish. Plus, it’s SO pretty too! I love how the green, yellow and red colors from the sliced vegetables look together. This is definitely one of those dishes that looks fancy but is so easy to make! My kind of dish. :)

    What is in the dish ratatouille?

    Ratatouille starts with a simple tomato garlic base. Then there is a mixture of zucchini, squash and eggplant (if you prefer it). Then you’ll add some fresh herbs to the top, such as fresh thyme, basil or parsley. All of this goodness bakes together to make the most delicious and fresh ratatouille dish!

    Vegetables to include

    I like to use fresh vegetables from my local farmer’s market. I used to pick the vegetables from my garden when we lived back in Ohio. It was the perfect way to use them all up!

    • Tomatoes: Tomatoes are the main foundation for ratatouille. I used canned diced tomatoes (15 oz, drained), however you can definitely use fresh tomatoes. Just dice them up first.
    • Onions: Onions add a fragrant and flavorful touch. I used white diced onions.
    • Eggplant: Eggplant is hit or miss with most people, however I think it pairs perfectly with the other vegetables in this dish You can omit or replace with more zucchini or squash.
    • Zucchini and Yellow Squash: I like to use fresh zucchini and yellow squash from the farmer’s market. The squash add a mild and somewhat sweet flavor.
    • Red Bell Pepper: The red bell pepper is super flavorful and is also a fragrant and delicious component.

    How to make ratatouille

    1. Tomato layer. Spread the tomatoes over the bottom of a 9×9″ dish. Stir in the onions, garlic, 1/2 teaspoon salt and 1/4 teaspoon pepper.
    2. Add remaining veggies. Layer the eggplant. zucchini and yellow squash. Fill the red pepper in the gaps.
    3. Add seasonings. Drizzle the olive oil over the top. Sprinkle thyme leaves and remaining salt and pepper over top.
    4. Bake in oven. Cover with foil and bake at 400°F for 30 minutes. Remove foil and bake an additional 10 minutes, or until vegetables are tender.

    Quick tips

    • Most of the work goes into slicing the vegetables. To make that part easier, try using a mandoline slicer.
    • The traditional ratatouille recipe doesn’t call for meat, however you can add it in. Try mixing cooked ground beef or sausage into the tomato garlic base.
    • For serving, top with freshly shaved parmesan or mascarpone cheese if desired.
    • Baked ratatouille pairs perfectly with a piece of crusty french bread.
