Straightforward Ratatouille recipe within the oven
Ratatouille is a basic French dish that’s wealthy, comforting, and excellent for sopping up with a bit of crusty artisan bread or ladling over a bowl of polenta. Like many conventional recipes, there are numerous variations on the market—and mine takes a little bit of a twist.
Quite than stewing the greens collectively in a pot, I selected to make an oven roasted ratatouille, which is a typical different to the stewed model. Not solely is oven roasting the sliced greens tremendous fairly, however it’s a little bit extra hands-off than stewing greens in a pot, which I recognize. I additionally added marinara sauce to the underside of my casserole dish, which finally ends up mixing with the juices from the greens and creating essentially the most scrumptious sauce (get some bread prepared for dipping). Lastly, I topped with cheese, which positively isn’t the norm for ratatouille, however it certain was scrumptious!
- This recipe is extraordinarily versatile. I’ve given some approximate weight values for the greens beneath, however you possibly can actually use no matter dimension you have got obtainable and no matter you possibly can squeeze into your baking dish. However a phrase of recommendation: as soon as sliced, the amount of the greens at all times finally ends up being greater than you estimated, so err on the facet of smaller greens.
- I don’t peel my greens because the skins assist maintain their form and add colour to the completed dish. Nevertheless, be at liberty to peel your veggies if most well-liked!
- Use tender veggies (and slice them evenly). Whereas this recipe is my straightforward oven-roasted model, I saved the greens true to a basic ratatouille recipe through the use of eggplant, zucchini, tomatoes, and onions. If you wish to change issues up, you possibly can combine in different tender veggies like purple or orange bell peppers, sliced mushrooms, or different tomato varieties like beefsteak tomatoes. Simply be certain that every thing is lower to about the identical thickness so the layers prepare dinner evenly.
