Make Ahead Tip: Roast vegetables (Step 2) up to 30 minutes ahead. Prepare the sauce (Step 3), cover and refrigerate for up to 1 day; gently reheat until steaming before combining with the vegetables.
To prep parsnips, peel with a vegetable peeler, then quarter lengthwise and cut out the fibrous, woody core with a paring knife before dicing.
To make your own fresh breadcrumbs, trim crusts from whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. One slice of bread makes about 1/2 cup fresh breadcrumbs.
To add extra flavor to the cream sauce, at the end of Step 3 stir in 1 tablespoon chopped fresh herbs, such as thyme, sage or parsley. Or make it cheesy by stirring in 1/2 cup shredded or crumbled cheese, such as Gruyère, Swiss, Cheddar or blue cheese.
Keep food fresh: If you're storing food in your fridge for a few hours or more, it's best to keep it in an airtight container or in a container covered tightly with foil. Foil is best at creating a barrier that doesn't let unwanted flavors in (or out) while you store your food.
