Instructions
Prepare your vegetables: wash the yellow squash and zucchini and slice them thin. Peel and slice the carrot. Chop the onion into small pieces so it cooks evenly.
In a medium pot, combine the sliced yellow squash, sliced zucchini, chopped onion, and sliced carrot. Add enough water to the pot to just cover the vegetables.
Cover the pot and bring the water to a boil over medium-high heat. Once boiling, reduce heat slightly and cook for 6 minutes. The vegetables should be tender but not falling apart.
Drain the vegetables very well using a colander or sieve. Let them sit a minute to release excess steam and moisture so your casserole won’t be watery.
Mash the drained vegetable mixture in a bowl until mostly smooth but with a little texture remaining. You can use a potato masher or a fork.
Stir in the 2 tablespoons butter, 2 tablespoons sugar, 1/2 teaspoon salt, 1/2 teaspoon pepper, and the beaten large egg. Mix thoroughly so the egg acts as a binder.
Add the 1/2 cup fresh breadcrumbs and 3/4 cup shredded cheddar cheese if using. Stir until evenly combined.
Pour the mixture into a lightly greased 1.5 quart casserole dish, spreading it into an even layer.
Bake in a preheated 350 degree oven for 25 to 30 minutes, or until the top begins to brown and the casserole is set in the center. If you like a darker crust, place under the broiler for 1 to 2 minutes while watching carefully.
Remove from the oven and let the casserole rest for 5 minutes before serving to firm up slightly.
Notes
Drain thoroughly to avoid a soggy casserole. Adjust the texture by mashing more for creaminess or leaving chunks for a rustic bite. Fresh breadcrumbs provide the best texture.
