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!
