- Taste as you go! Adjust salt and creaminess to your liking.
- Leftovers taste even better the next day, so make a big batch.
Leftovers and Storage
Got some soup left? Store it in an airtight container in the fridge for up to 3 days. Reheat gently on the stove or microwave, stirring occasionally to keep it smooth. You can also freeze portions in freezer-safe containers for up to 2 months. Just thaw overnight in the fridge before reheating.
Mistakes to Avoid
- Skimping on roasting time under-roasted peppers won’t develop that smoky flavor.
- Forgetting to peel the skins, which can make the soup gritty.
- Adding too much liquid at the start you can always add broth later if needed.
- Overheating after adding cream, which might cause it to curdle.
- Ignoring seasoning salt and pepper are your friends here.
