Cheesy Squash Casserole is the kind of side dish that will impress even the pickiest of eaters. Tender yellow squash and zucchini, savory bread crumbs and deliciously melty cheese make this side dish a total crowd pleaser!
Preheat the oven to 350 degrees and grease an 11" x 7" baking pan. Set aside.
Boil water and blanch zucchini, yellow squash and onions for 5-7 minutes until tender. Drain well.
Place vegetables in an even layer in the prepared pan.
Sprinkle and even layer of salt, pepper and sugar over the vegetables.
Pour milk evenly over the vegetables.
Sprinkle 1/2 cup cheese evenly over the vegetables.
Sprinkle the bread crumbs evenly over the vegetables.
Sprinkle the other 1/2 cup cheese evenly over the vegetables.
Scatter cubes of butter over the top of the casserole.
Bake for 30 minutes or until golden brown (you can also broil it for the last 2 minutes, just keep an eye on it, so it doesn't burn). Serve immediately.
