If I could cook everything in the oven, I think I probably would. I use my oven all the time to whip up easy side dishes, create pasta sauces, cook entire main meals, preserve the tomato harvest, cook lunchbox treats for The Princess, and then there is dessert. I love the freedom that the oven gives me. I don’t stress about a dish catching on the bottom of the pan and burning, and I can carry on with other things whilst dinner is cooking. I can even put something in the oven and dash out to run errands without fear of burning the house down.
Whilst I know a slow cooker provides all the convenience of the oven, what a slow cooker cannot do is add that extra dimension to a dish that an oven does. In the oven, flavours concentrate and edges caramelise, and crispy bits develop, all of which add to the eating experience. I love my oven so much that I am constantly converting conventional recipes to oven baked versions. And this oven baked ratatouille recipe is case in point.

Ingredient Substitutions for my Baked Ratatouille Recipe
Ratatouille is all about the vegetables, and the synergy that develops between the eggplant, zucchini, capsicum and tomato as it cooks. You can play around with the quantities of these vegetables to achieve a balance that suits your personal palate, but I don’t advocate removing any one type of vegetable completely if you wish to retain the flavour of the dish. Other ways you might consider to make it your own:
- Use only one type of capsicum (pepper). I use the red and the yellow for visual appeal, but you can easily just use one colour. Red and yellow peppers are sweeter than green, but if green is all you have then use them instead.
- Replace the red onions with brown onions.
- Try a good tomato pasta sauce in place of the tomato passata.
- Use 1/4 teaspoon of dried thyme in place of the fresh thyme, or omit it completely.
- Replace the fresh garlic with 2 teaspoons garlic powder.
- Use1 teaspoon of dried basil in place of the fresh basil.
- Fresh or dried bay leaves may be used interchangeably in this recipe.
Baked Ratatouille Recipe: A few Tips & Tricks
This baked ratatouille recipe is so easy that once you try it I promise you that you will never make any other way again. Oven roasted ratatouille is a great way to use up a glut of summer vegetables, and as it freezes so well why not make a double batch and stash it in the freezer for the winter months. As easy as this dish is, I have a few extra tips for you:
- The key to this dish is roasting the zucchini, capsicum, onion and eggplant before adding the tomato passata. Roasting concentrates the flavours of the vegetables by removing some of the water, which will result in a thicker sauce.
- I like to roast my garlic at the same time as the vegetables, then squeeze the silky puree into the base of the pan when adding the tomato. If you are using garlic powder, just stir this is with the rest of the dried herbs.
- Make sure your roasting tray is large enough that the vegetables aren’t overcrowded, as they will stew instead of roasting. I use my largest roasting pan for this dish. If your tray is not big enough, split the vegetables between two baking trays for the initial roasting. Once the vegetables are roasted, combine them on one tray to finish the dish.
- To freeze this baked ratatouille recipe, allow the ratatouille to cool before dividing it into freezer-safe containers. Label the containers and freeze for up to three months.
