Drying the blanched broccoli well prevents a watery casserole and helps the sauce cling to the florets. For a stronger ranch flavor, use a thick, high-quality ranch or whisk 1 tablespoon dry ranch seasoning into the sauce. You can substitute cauliflower for half the broccoli or skip the chicken for a vegetarian version (keep the bacon or replace it with crispy fried shallots). If preparing ahead, assemble up to step 7, cover, and refrigerate for up to 24 hours; add 5–10 minutes to the bake time. For gluten-free, use gluten-free panko or omit the breadcrumbs and add extra Parmesan. Leftovers reheat well at 350°F, covered, for 15 minutes or microwave in short bursts to keep the topping crisp.
