Why This Recipe Works

Ratatouille is, at its core, roasted seasoned vegetables. That’s something that your air fryer is actually really good at doing! 

It takes less time to cook and heats up your house far less than turning on your range oven. That’s important, since ratatouille is best with fresh summer vegetables (meaning it’s hot outside).

You can use whatever vegetables you have on hand as well, though, making it super versatile. Eggplant, zucchini, tomatoes, bell pepper, and onions are most traditional. However, I’ve seen potatoes, carrots, beets, and other veggies swapped in for variations!

If you love those vegetables and want an alternative to french fries, then try making these Aldi eggplant fries in the air fryer.

Ingredient Substitutions and Variations

  • Vegetables. Honestly this recipe can be done with any variety of vegetables. I prefer slices for the look, but you can cube them as well. Add or swap in potatoes, sweet potatoes, beets, carrots, bell peppers, or whatever else you like

Recipe FAQs

Can You Cook Ratatouille in an Air Fryer?

Yes, you can cook ratatouille in an air fryer.

It will lightly brown the vegetables and cook them to a soft state. It takes less time and puts off less heat than using the standard oven preparation.

Does Eggplant Need to Be Peeled for Ratatouille?

No, eggplant does not need to be peeled for ratatouille.

However, you can if you prefer. It does add a slightly tougher texture, but the color contrast with the other vegetables makes it look very pleasing.

How Should I Cut My Vegetables for Ratatouille?

Vegetables can either be cut in thin slices or cubes for ratatouille.

The slices make a more elegant presentation, but generally take longer to make all the cuts. Regardless of the way they are cut, make sure your pieces are as even as possible for uniform cooking.

Do I Need to Salt My Eggplant Before Making Ratatouille?

You do not need to salt eggplant before making ratatouille. That will actually soften it, so it doesn’t retain its shape well when assembling the dish.

That said, salt should be added to all of the vegetables as part of cooking for flavor. You simply don’t need to salt and let eggplant sit ahead of time.

Recipe Pro Tips

  • If you use sliced vegetables, you do not need to flip during cooking. If you’ve cubed them instead, I do recommend stirring them once midway to promote even cooking
  • For very large diameter vegetables, feel free to cut in half and use half-moon shaped slices. Pack small slices into gaps between larger ones
  • I have a Ninja Foodi Dual Zone air fryer, so I’ve used two small casserole dishes. However, you can use a singular large one in a one-basket air fryer
  • Messy as it is, I recommend using your hands to toss the vegetables in the oil and seasonings. The tomatoes and eggplant are delicate and tend to fall apart if you try and use utensils
  • For me, 25 minutes of cooking time was perfect but other air fryers may vary. Thickness of vegetables can make a difference as well
  • Make sure to spray your casserole dish with nonstick spray if it doesn’t have a nonstick coating on it
