Ingredient Notes:
(Here are a few notes about the ingredients you’ll need for this recipe. As always find the full list of ingredients and directions in the recipe card at the bottom of the post.)
- Tomatoes - I like Campari or vine tomatoes best as they are flavorful and easy to find.
- Zucchini – Choose small to medium sized zucchini and avoid large ones which can be both spongey and filled with seeds.
- Bell Peppers – I like a mix of both red and orange bell peppers for color but either one will do.
- Olives - Choose Kalamata olives for the best flavor
- Olive Oil – Use your favorite extra-virgin olive oil.
- Garlic – A little finely minced garlic brings lots of flavor to this easy dish.
- Fresh Herbs – We’re using a mixture of fresh thyme, basil and parsley.
- Vinegar – Use a good quality balsamic vinegar for the best flavor.

How to Make Marinated Roasted Vegetables:
(Here are the basic steps and some helpful tips on how to make the recipe. Find the full directions in the recipe card at the bottom of the post.)
- Start by cutting the vegetables into similarly sized pieces to ensure they cook evenly.
- Then toss them with some olive oil, garlic, thyme and a bit of salt and pepper.
- They’ll go into the oven to roast while you make the marinade. We are marinating the vegetables AFTER they come out of the oven when they will best absorb the flavors of the marinade as opposed to before. The vegetables then continue to marinate and develop in flavor as they rest. You can serve the marinated vegetables immediately, at room temperature or store them in the fridge in their marinade and use them cold.
- The marinade is a simple combination of balsamic vinegar and olive oil with some basil and parsley added for freshness. Whisk the mixture together then pour it over the still warm vegetables as they come out of the oven and allow them to sit before serving.
Healthy, flavorful and easy to prepare, these roasted marinated vegetables will be the star of your late summer/ early fall meals.
Variations:
- Add eggplant for a ratatouille-inspired version.
- Serve with chickpeas or lentils for a vegetarian main meal.
- Use in salads, wraps and sandwiches.
- Toss with pasta.
- Add to an antipasto platter.

Oh Sylvie - what a gorgeous post! That last picture had me totally mesmerised. I also love trying to capture the essence of summer and love preserving slow-roast tomatoes in this way. The idea of this on polenta is just super-decadent. My only tip to readers is to make SURE that the vegetables are COMPLETELY covered in oil - if bits stick up above the surface of the oil you risk getting mould, even in the fridge.
Sylvie says
Yes, you are absolutely right, keeping the vegetables fully covered is very important. Thanks for pointing that out.

I like how those gorgeous veggies are layered into the jars. I love to roast tomatoes and use them in various ways, but have never thought to package my roasting so beautifully. Just lovely.
