For a richer flavor, try using a blend of Gruyere and sharp Cheddar. To add a touch of heat, incorporate a pinch of red pepper flakes when seasoning the squash. If you don't have sweetened condensed milk, a drizzle of heavy cream or half-and-half will work in a pinch.

Follow The Directions
01
StepPreheat oven to 350 degrees F (175 degrees C). Grease a 9x9-inch baking dish with about 1/2 tablespoon of butter.
02
StepMelt remaining 1 tablespoon of butter in a large cast-iron skillet over medium heat, and cook the summer squash and zucchini until the squash pieces begin to brown, 10 to 15 minutes, stirring often. Sprinkle with salt and black pepper, and spread into the bottom of the prepared baking dish. Sprinkle with about 1/3 of the chopped onions.
03
StepMix together the white Cheddar cheese and yellow Cheddar cheese in a bowl until thoroughly combined, and sprinkle about 1/2 cup of the cheese mixture over the onions. Drizzle with about 1 tablespoon of the sweetened condensed milk. Repeat sprinkling cheese, onions, and condensed milk twice more, then top with remaining cheese mixture.
04
StepBake in the preheated oven until the casserole is golden brown and the onions are tender, about 30 minutes.
