Tips for casserole success (and make-ahead tricks)

• Use a reliable baking dish size: many of these are written for a 9×13-inch (or equivalent) pan or slightly smaller. Adjust time if using individual ramekins.
• Make it gluten-free: swap regular pasta, breadcrumbs, and cornbread mixes for gluten-free versions.
• Make it dairy-free: use plant-based milk and cheese alternatives; thicken sauces with a cornstarch slurry.
• Freezer-friendly: assemble without baking, wrap tightly, and freeze up to 3 months. Thaw overnight in the fridge and bake as directed (add ~10–20 minutes).
• Reheating: cover with foil and reheat at 350°F until warmed through, or microwave individual portions.
• Flavor boosts: fresh herbs, a squeeze of lemon, hot sauce, or a sprinkle of flaky sea salt after baking brightens casserole flavors.
• Crispy topping: to keep breadcrumbs crisp, toss crumbs with melted butter and add for the last 10 minutes of baking.
