Optional additions that many cooks swear by: 1 tablespoon Dijon mustard stirred into the sauce before cooking adds a pleasant sharpness; a splash of orange juice adds brightness; 1 packet dry onion soup mix adds savory depth and is a classic variation; a quarter cup of French or Catalina dressing adds tanginess and a slightly different flavor profile. Any of these are additions, not requirements — the three-ingredient base is excellent as it stands.
Instructions
Step 1: Prepare the Slow Cooker
Lightly spray the interior of a 4 to 6 quart slow cooker with cooking spray to make cleanup easier later. This step is optional but worthwhile — cranberry sauce can leave a sticky residue on the sides of the insert after a long cook, and a light coating of spray makes the cleanup considerably faster.
