Zucchini Ratatouille N: A Simple French Inspired Roasted Vegetable Dish

Daily Recipe: June 21, 2025

Summer is here, and with it comes an abundance of fresh zucchini just begging to be roasted. This Zucchini Ratatouille Niçoise is my answer to a keto friendly, French inspired vegetable dish that feels both elegant and effortless.

It all started last June when my garden gave me more zucchini than I knew what to do with. I wanted something that captured the Provencal flavors I love, but without the starchy eggplant traditional ratatouille calls for.

Swapping in thin rounds of zucchini keeps every bite tender, low in carbs, and bursting with herbs.

this …

The real magic here is how the cherry tomatoes break down into a garlicky, thyme infused base while the peppers and zucchini roast until their edges caramelize.

It is a dish that tastes like a sunny afternoon on the French Riviera, yet it comes together in about 40 minutes start to finish.

I often make it when I need a light main course that still feels special, or as a colorful side next to grilled fish.

For anyone following a keto diet, this ratatouille is a lifesaver: it ditches the aubergine entirely while keeping all the bright, herby character you would expect from a traditional ratatouille niçoise. Even my picky eaters clean their plates when this hits the table.

Today I am sharing it as a daily recipe for June 21, 2025, but really, this dish deserves a spot in your rotation all summer long.

Whether you pick your zucchini from the farmers’ market or your own backyard, you will love how simple it is to prep. Just a little slicing, a quick saute, and the oven does the rest. No complicated steps, no hard to find ingredients.

That is the kind of cooking that makes me happiest, and I hope it does the same for you.

Ingredients (for 2)

This recipe uses simple, fresh ingredients you likely already have on hand. Because we are aiming for a keto friendly roasted vegetable dish, every component pulls double duty: it adds flavor while keeping the carb count low.

I always raid my herb patch for the basil and thyme, but dried herbs will work in a pinch. Here is what you need for 2 generous servings:

• 2 large zucchini, sliced into thin rounds
• 1 red bell pepper and 1 yellow bell pepper, julienned
• 15 cherry tomatoes, halved
• 4 garlic cloves, minced
• A handful fresh basil, chopped
• A few fresh thyme sprigs, leaves picked
• 2 tablespoons olive oil
• Salt, to taste
• Freshly ground black pepper, to taste

Notice we skip the eggplant entirely, making this a true low carb ratatouille. The bell peppers and cherry tomatoes provide plenty of natural sweetness, while the garlic and herbs bring a savory depth that ties everything together.

If you only have one color of bell pepper, that is perfectly fine; I like the mix because it makes the finished dish so pretty.

Preparation

1. ️️ Preheat the oven to 200°C (392°F). Before anything else, get your oven hot. A proper preheat is the secret to getting those caramelized edges on the vegetables without steaming them. While the oven warms up, you can slice and julienne everything.
2. Heat olive oil in a large skillet over medium heat. Add minced garlic and fry until golden. I pour the 2 tablespoons of olive oil into a wide skillet, swirl it around, and add the garlic. It only takes a minute or two to turn fragrant and golden; be careful not to burn it or the dish will turn bitter.
3. Add halved cherry tomatoes to the skillet. Season with salt, pepper, and a pinch of fresh thyme. Cook for about 5 minutes, until tomatoes start to break down. The tomatoes release their juices and mingle with the garlicky oil, creating a rustic foundation for the ratatouille. Stir now and then, and don’t rush this step; you want them soft and jammy.
4. ️️ Spread the cooked tomato mixture on a roasting dish, then arrange thin zucchini slices and julienned bell peppers in alternating patterns on top. I use a shallow baking dish so the vegetables roast instead of steam. Layering them in a pretty pattern is optional, but it makes the final presentation feel truly French and impressive.
5. ️ Drizzle vegetables with olive oil. Season with the rest of the fresh thyme, salt, and pepper. Roast for 20 minutes, or until vegetables are tender and slightly caramelized. A tiny extra drizzle of olive oil helps the zucchini rounds and pepper strips develop those golden brown spots. Check them after 20 minutes; you want them fork tender with concentrated flavor.
6. ️ Garnish the roasted vegetables with chopped fresh basil before serving. Fresh basil goes on at the very end so it stays bright and aromatic. The dish can be served hot, warm, or even at room temperature, which makes it perfect for make ahead meals or summer entertaining.

Additional

This dish quickly became a year round staple in my kitchen, but it truly shines when fresh zucchini is in season and you can pull them straight from your backyard or a local farmers’ market.

The tender rounds soak up all the herby tomato goodness, and the peppers add just the right amount of crunch. If you want to turn it into a more substantial main course, you can easily add chunks of chicken, shrimp, or even sausage before roasting.

I have done this on busy weeknights when I needed a one pan dinner, and it works beautifully; just make sure the protein is cut small so it cooks through in the same amount of time.

Serving ideas are endless. A slice of crusty bread alongside is classic if you are not strictly keto, but for a fully low carb meal, I love spooning this ratatouille over a bed of cauliflower rice or pairing it with a simple green salad.

It also goes wonderfully next to grilled fish or roasted chicken. For another low carb zucchini dish, try my low carb zucchini au gratin casserole, which has a creamy, cheesy twist that complements this herby ratatouille beautifully.

And if you are in the mood for a more rustic roasted plate, my garlic herb roasted potatoes and zucchini can be the perfect non keto companion for a family style dinner.

Leftovers keep well in the fridge for a few days; I often pack them for lunch because the flavors meld even more overnight. Reheat gently so the zucchini stays firm, or simply enjoy it at room temperature the Provencal way.

For another keto friendly take on this dish, you might enjoy browsing this zucchini ratatouille recipe from Wholesome Yum, which uses a similar approach.

And if you want a classic foundation, BBC Good Food’s best zucchini ratatouille niçoise offers a lovely traditional version you can adapt.

One last tip: when you are arranging the vegetables in the roasting dish, try not to overcrowd them. Give each slice and strip a little room so the dry heat of the oven can do its caramelizing work.

This small detail makes the difference between a dish that is simply cooked and one that has those deeply flavorful, slightly singed edges we all love.
