Make a flavorful Air Fryer Ratatouille with eggplant, zucchini, yellow squash, tomatoes, onions, garlic and spices, and topped with Parmesan.
Trim ends off eggplant, zucchini, yellow squash and tomatoes. Slice them into rounds approx. ¼" thick. Place sliced vegetable in a large bowl.
In a separate small bowl, stir olive oil, salt, pepper, oregano and basil until combined. Pour onto the sliced veggies. GENTLY toss veggies until they're well-covered. Set bowl aside.
The casserole dish/pan you use must be oven-proof and fit easily inside the basket of the air fryer. Spray the bottom and sides with non-stick spray. In a small bowl, combine diced onion and minced garlic; spread evenly on the bottom of the greased pan.
Arrange sliced vegetables in the pan (on TOP of the onions and garlic). Stand the veggie slices on end, overlapping/alternating veggies (and colors). Start around the edges of the pan; work into the center to create a colorful looking ratatouille.
Preheat air fryer to 400°F. (200°C.). Once heated, place ratatouille into the basket of the air fryer. Cook at 400°F. for 15-20 minutes until fully roasted. IMPORTANT TIP: Check on the veggies around the 10–12-minute mark to ensure they don't overcook. The size of vegetable slices used, and varying temperatures of air fryers can lead to differing results, so please keep an eye on the vegetables! When ratatouille is done, veggies should be well-browned and tender.
Once done, pull basket out of air fryer. Garnish veggies immediately with finely grated Parmesan (while veggies are hot). Put ratatouille back in the air fryer, but DON'T COOK IT ANYMORE. Residual heat remaining in the air fryer will melt the Parmesan cheese (about 1 minute). Once cheese melts, remove and serve the ratatouille while hot. Enjoy!
NOTE: The Parmesan cheese for garnish has not been included in the caloric calculation, as varying amounts may be added, depending on the user.
