How to Properly Store It?
To prevent it from spoiling, proper storage is crucial. Here’s how to keep your Southern Sweet Onion Casserole last longer:
- First, allow the casserole to cool completely before storing it. Do not leave it at room temperature for more than two hours too. Doing so may increase the risk of bacterial growth.
- Next, transfer the casserole to an airtight container or a baking dish. Cover it using aluminum foil or plastic wrap.
You can also divide the casserole into smaller portions for easier storage and reheating.
- Once done, store the casserole in the fridge for up to three days. If you want to last as long as three months, you can keep it in the freezer instead.
Label the container with the date and name of the dish for convenience.
Are there Other Alternative Ingredients?
If you want to make a southern sweet onion casserole without using onions, you can try some alternative ingredients that can mimic the flavor and texture of onions.
Here are some suggestions:
- Shallots. Shallots are similar to onions but have a milder and sweeter taste. They can be used in place of onions in most recipes, especially soups, sauces, and casseroles. You will need to use more shallots than onions, as they are smaller in size.
For example, if a recipe calls for one large onion, you can use about six small shallots.
- Leeks. Leeks are another member of the onion family. The only difference is that it has a more delicate and refined flavor.
