We are obsessed with this delicious Zucchini, Squash & Corn Casserole. Fresh veggies and cheese are hard to beat! We've made this several times over the past month and it has been a hit every time. We really like it with grilled chicken and burgers.

This Zucchini, Squash & Corn Casserole can be made in advance and refrigerated overnight. I've even divided the casserole between two foil pans and frozen one for a quick side later.

This recipe uses "fresh breadcrumbs". To make fresh breadcrumbs, just pop some bread slices in the food processor and pulse it a few times. I used homemade bread, but any type of bread will work just fine.

This Zucchini, Squash & Corn Casserole is going to be a staple in our house this spring and summer. This casserole is great for potlucks and cookouts. We are serving it this weekend with our Easter ham!

    1. Cauliflower rice for the corn, and crushed pork skins for the bread crumbs !

  3. Can you make it ahead and bake it later? How much extra time if it was refrigerated?

    1. You can make it ahead. I would add about 15 minutes if you are baking it after being refrigerated

  4. Blending the two types of squash together with the cheese and corn does make a very pretty dish. It also sound delicious and very easy to prepare.

  5. I, too, would like to serve this with Easter dinner. Guessing you use frozen corn kernels this time of year?
