Step 2: Add a layer of zucchinis overlapping in rows in a container. I used a small pan for my vegetarian zucchini bake.

Depending on your air fryer will depend how large or small your pan needs to be. Just make sure it is air fryer safe.

Step 3: Keep layering and alternating with parmesan cheese. Do this until your pan is full of zucchini.

Step 5: Pop in the Air Fryer and cook. Or you can bake in the oven if you would prefer.

Expert Tips 

Here are some tips and tricks for making this air fryer zucchini casserole! Cooking zucchini is so easy. We loved this recipe.

  • Make certain that you try and cut your zucchini slices all the same length and thickness. This will help them cook up evenly and provide a much better overall texture, too. 
  • Don’t skimp on the parmesan! It really does add a lot of great flavor between all the layers of zucchini. 
  • Peeling the zucchini is up to you. Some people like to peel them all the way while others leave the outside because it holds them together better. (Just make certain that whatever you decide, you wash and clean off the outside well!)

Zucchini Casserole Recipe

Yield: 1 casserole
Prep Time: 5 minutes
Cook Time: 20 minutes
Total Time: 25 minutes

Zucchini Casserole Recipe is a cheesy zucchini casserole you can bake in the oven or air fry. Layers of zucchini and parmesan that are mixed with a creamy sauce and baked perfectly. The ultimate zucchini side dish recipe.

Ingredients

  • 2-3 Zucchini - medium-sized
  • 1 cup parmesan cheese
  • ¼ cup heavy cream
  • 2 tablespoons butter
  • 1 tablespoon garlic, minced
  • Salt to taste

Instructions

  1. Wash your zucchini thinly. I used a mandoline for slicing the zucchini. You want to slice the zucchini all the same size for even cooking.
  2. You want to overlap the zucchini so it kind of stacks on each other.
  3. Sprinkle with some of your parmesan cheese. Then you will add another layer of zucchini slices on top, and add more cheese.
  4. Now add your third and final layer of zucchini slices and the rest of the parmesan cheese.
  5. In a skillet, you will add your butter, garlic, and heavy cream into a skillet. Whisk until melted and it is thickening.
  6. Pour the sauce over the zucchini mixture.
  7. Place in an air fryer at 375 degrees or in the oven (same temp), and cook until melted. My casserole took 18 minutes to cook.
  8. Once the zucchini casserole is done then allow it to cool for 5 minutes and then serve.

Notes

You can use summer squash and zucchini, straight summer squash, or just zucchini.

I did 3 layers of zucchini but feel free to do however many layers as you would like.

The heavy cream and butter add richness to the zucchini casserole that you wouldn't get otherwise.

Store your leftover casserole in the fridge in an airtight container. You will find this zucchini bake does not freeze well as it will soften the zucchini quite a bit.
