Classic Chicken and Broccoli Casserole with Crispy Cracker Topping

This casserole is the kind of dish that reliably comforts a crowd without demanding a day in the kitchen — tender chicken and bright green broccoli bound in a tangy, savory cream sauce and finished with a buttery, crackly cracker crust. What makes this version work is balance: sharp cheddar folded through the filling gives enough bite to cut through the richness, sour cream (or thick Greek yogurt) adds brightness and silkiness, and the cracker topping provides the quick, nostalgic crunch that contrasts beautifully with the creamy interior. Blanching the broccoli instead of overcooking it keeps those florets slightly toothsome and vividly green so the casserole doesn’t become a homogenous mush.

This is a recipe that thrives on convenience without sacrificing flavor — think rotisserie chicken to speed things up, or poached breasts shredded right into the sauce. Small technique choices (patting the broccoli dry, using just enough milk to make the sauce pourable, and toasting the cracker crumbs briefly) make a big difference in texture. It’s equally at home as a weeknight supper stretched with a simple salad, or as a potluck centerpiece that feeds a hungry group and travels well when covered and reheated gently.
