How To Store / Freeze This Soup
Allow the French onion soup to cool to room temperature before storing. This prevents condensation and keeps the soup fresh.
Transfer the cooled soup into airtight containers. For best results, use containers that are specifically designed for freezing to avoid freezer burn.
If you plan to store the soup in the refrigerator, it will keep well for up to 3-4 days. Make sure the containers are sealed tightly to maintain the soup's rich flavors.
For longer storage, freeze the soup. It can be frozen for up to 3 months without losing its savory taste. Label the containers with the date to keep track of freshness.
When ready to enjoy, thaw the frozen soup in the refrigerator overnight. This slow thawing process helps preserve the texture and taste of the caramelized onions and beef broth.
Reheat the soup on the stovetop over medium heat, stirring occasionally until it reaches a simmer. This gentle reheating ensures that the flavors meld beautifully.
If you have leftover baguette slices and gruyere cheese, store them separately. Keep the bread in a sealed bag at room temperature for up to 2 days, and the cheese in the refrigerator for up to a week.
When serving reheated soup, follow the original recipe's steps for topping with bread and cheese. Broil until the cheese is melted and bubbly, recreating that delightful, comforting finish.
How To Reheat Leftovers
- Gently reheat the French onion soup on the stovetop over medium-low heat. Stir occasionally to ensure even heating and prevent the onions from sticking to the bottom of the pot.
- For a quick option, microwave the soup in a microwave-safe bowl. Cover the bowl with a microwave-safe lid or plate to avoid splatters. Heat in 1-minute intervals, stirring in between, until the soup is hot.
- If you want to recreate the original broiled cheese topping, ladle the reheated soup into oven-safe bowls. Top with fresh slices of baguette and a generous amount of gruyere cheese. Broil in the oven until the cheese is melted and bubbly, about 3-5 minutes.
- For an added touch, you can toast the baguette slices separately in a toaster or oven before placing them on top of the soup. This ensures they remain crispy even after being submerged in the soup.
- If you have a slow cooker, you can reheat the soup on the low setting. This method is perfect for reheating larger quantities and keeping the soup warm for extended periods without overcooking.
