Ingredients

Sauce:
2 1/2 tablespoons butter
2 1/2 tablespoons all purpose flour
1 1/2 cups whole milk, hot
3/4 cup (packed) coarsely grated extra-sharp white cheddar cheese
1/4 teaspoon hot pepper sauce
Vegetables:
2 tablespoons olive oil, divided
1 pound medium-size yellow crookneck squash, trimmed, cut into 1/2-inch-thick rounds
1 pound medium-size zucchini, trimmed, cut into 1/2-inch-thick rounds
1 1/4 cups diced onion
1 cup diced red bell pepper
1 garlic clove, minced
1 cup frozen corn kernels, thawed
1 teaspoon chopped fresh rosemary
1 tablespoon butter, cut into 1/2-inch cubes
Topping:
1 1/2 cups (packed) fresh breadcrumbs made from crusty French bread (do not remove crust)
1/2 cup (packed) coarsely grated extra-sharp white cheddar cheese (about 2 ounces)
1 1/2 tablespoons butter, melted

Steps:

For sauce:
Melt butter in heavy medium skillet over medium heat. Add flour and whisk 1 minute. Whisk in hot milk; whisk until mixture boils, thickens, and is smooth, about 5 minutes. Remove from heat. Add cheese and hot pepper sauce and whisk until cheese melts. Season sauce to taste with salt and pepper.
For vegetables:
Butter 11x7x2-inch glass baking dish. Heat 1/2 tablespoon oil in large nonstick skillet over medium-high heat. Add half of yellow squash and half of zucchini; sauté until crisp-tender, about 4 minutes. Transfer squash-zucchini mixture to large bowl. Repeat with 1/2 tablespoon oil and remaining yellow squash and zucchini.
Heat remaining 1 tablespoon oil in same skillet over medium-high heat. Add onion, bell pepper, and garlic; sauté until onion is golden and pepper is tender, about 7 minutes. Stir in corn and rosemary. Transfer to bowl with squash-zucchini mixture. Mix in cheese sauce. Season to taste with salt and pepper. Transfer mixture to prepared dish. Dot with butter. (Can be prepared 1 day ahead. Cool slightly. Cover with foil and refrigerate. Before continuing, heat covered gratin in 400°F oven until warm but not hot, about 20 minutes.)
For topping:
Preheat oven to 400°F. Mix breadcrumbs, cheese, and melted butter in bowl until crumbs are coated with butter. Sprinkle crumbs evenly over gratin. Bake until vegetables are heated through and crumbs are crisp and golden, about 35 minutes.

I had some trouble getting the cheddar crust to brown. I ended up putting the dish under the broiler for a few minutes.

I thought this dish was just okay. The flavors were a bit bland for my taste.

This was an easy and delicious side dish. I served it with grilled chicken and it was a perfect complement.

I love scalloped potatoes, so I was excited to try this recipe. I wasn't disappointed! The squash, red pepper, and corn added a nice twist to the classic dish. The cheddar crust was also a great addition.

I made this for dinner last night and it was a huge hit! My kids loved the sweet and savory flavors of the squash, red pepper, and corn. The cheddar crust was the perfect finishing touch. I will definitely be making this again.
