Make Ahead Tip:
If making ahead or freezing, prepare stew through Step 3. Simmer for 5 minutes over low heat; remove from heat and cool in the pot or in freezer-safe container. Transfer to the fridge (store for up to 3 days) or freezer. The vegetables store better if not fully-cooked prior to refrigeration or freezing. When ready to eat, (if frozen) thaw in refrigerator for 24 to 48 hours, then pour stew into a pot, bring just to a boil, and simmer until heated through.
