Why I Love This Recipe

This skillet ratatouille recipe contains a bunch of my favorite flavors and it’s full of vegetables. Plus, this recipe is not an exact science, and you can swap in whatever you have. A pinch of this… a little bit of that… this is my kind of recipe. It’s a great way to use up seasonal veggies like eggplant and summer squash!

Tips for the Perfect Ratatouille

  • Try to cut your zucchini, squash, and eggplant into uniformly sized pieces. This will ensure that all the vegetables cook at the same rate.
  • If you don’t have a cast-iron skillet, you can make this in a regular skillet. Avoid aluminum pans, if you can. The acidic tomatoes react with the aluminum, and it can create a slight metallic taste in your food.
  • Tie your bundle of thyme together tightly, so it’s easy to remove from the pan after cooking.

Ratatouille Ingredients

  • Olive oil– A little olive oil helps soften the onion and garlic and mellow the sharp flavors.
  • Onion– I used a white onion but you can use a white or yellow onion.
  • Garlic– Fresh garlic adds a deeper flavor.
  • Thyme– Fresh thyme adds a a savory flavor to the dish.
  • Tomatoes– I used canned whole tomatoes. You can substitute diced, if necessary.
  • Yellow squash– Sometimes called summer squash, this small squash is an essential component of ratatoullie. There’s no need to peel it.
  • Zucchini– This tender summer squash is a must have for this recipe. Similar to yellow squash, there’s no need to peel it.
  • Eggplant– Eggplant, which may also be called aubergine, is the third essential vegetable for ratatouille.
  • Red pepper flakes– I like adding a pinch of red pepper flakes for subtle heat.

How to Pick the Right Ingredients

A recipe is only as good as the ingredients, and since this recipe is pretty simple, you want to use the best produce possible! Here are a few tips for picking out perfect ingredients.

  • Use a high-quality brand of whole tomatoes. Muir Glen Organic has amazing whole peeled tomatoes that come in a can. I like to use whole rather than diced because diced tomatoes don’t break down as well.
  • When it comes to picking out an eggplant, look for one that is smaller in size with firm skin that doesn’t have any significant blemishes.
  • When choosing zucchini and yellow squash, look for smaller squash which will have fewer seeds and be less watery than larger squash.

Great ingredients equal great taste! You’re all set to make the perfect ratatouille!
