Makes 8 to 10 servings

Soft, white breadcrumbs double as a feather-light binder and golden crumb topping. To make them, pulse torn slices of day-old sandwich bread in the food processor.

How to Make It

Step 1

Preheat oven to 350°. Bring first 2 ingredients and water to cover to a boil in a Dutch oven over medium-high heat, and boil 5 minutes or until crisp-tender. Drain; gently press between paper towels.

Step 2

Melt 2 Tbsp. butter in a skillet over medium-high heat; add onion, and sauté 10 minutes or until tender. Add garlic, and sauté 2 minutes.

Step 3

Stir together squash, onion mixture, corn, next 6 ingredients, and 1/2 cup each breadcrumbs and Asiago cheese just until blended. Spoon mixture into a lightly greased 13- x 9-inch baking dish.

Step 4

Melt remaining 2 Tbsp. butter. Stir in remaining 1 cup breadcrumbs and 1/2 cup Asiago cheese. Sprinkle over casserole.

Step 5

Bake at 350° for 45 to 50 minutes or until golden brown and set. Let stand 15 minutes before serving.

Made this for a holiday dinner but this is great all year round. I made a few changes: 1) tossed the squash and zucchini in olive oil and pepper, then broiled versus boiling; 2) added pimentos for color; 3) agree with other posters on corn - I used frozen since fresh was out of season; 4) used garlic roasted bread crumbs. 

Definitely a Keeper!

Absolutely delicious!  I used day-old French bread for the breadcrumbs since that's what I had on hand but otherwise wouldn't change a thing - YUM!

This is absolutely delicious! My family, kids included love it. I follow the recipe exactly with the exception of adding more breadcrumbs to the top, just because my family loves it, not that the recipe needs to be adjusted. Since it is rich and creamy, we pair it with a simple grilled chicken like Lexington-style Grilled Chicken also found on the SL site.
