Boil vegetables into a broth

It's usually a good idea to keep broth on hand for a variety of recipes. There are several applications for broth, ranging from soups and stews to risotto and casseroles. That is why utilizing leftover vegetable scraps to create broth is such an excellent way to repurpose food that would otherwise go to waste. Making homemade vegetable broth from leftover scraps is much easier, as Tasty points out, and it's also customizable, so you can choose how much salt, among other things, is in the broth.

Simply put the leftovers (frozen or not) in a pot and fill them with water. To add flavor, you can also add aromatics like garlic or a bay leaf. Cook the broth for about 10 minutes. Depending on how soon you want to consume the broth, strain it through a strainer and store it in the fridge or freezer. According to the journal, a vegetable broth created from scraps would not thicken on its own and should be compared to store-bought stock.
