This chefs over at Tasty know their onions! This is a great way to save up scraps and put them to good use — and how to store the stock in different ways and amounts.
How to Make Easy Veggie Stock With Kitchen Scraps
Makes roughly 3 quarts
INGREDIENTS
Onions (tops, bottoms, and skins)
Celery (tops and bottoms)
Carrots (tops, bottoms, and skins)
Mushrooms (stems)
Garlic (tops, bottoms, and skins)
Potatoes (tops, bottoms, and skins)
Parsley (stems)
You can add many other vegetable scraps (think sweet!) – i.e. corn cobs, winter squash, zucchini, and other squash, beet greens, fennel, chard, lettuce, parsnips, green beans, pea pods, bell peppers, eggplant, mushrooms, asparagus, and herbs like dill, thyme, parsley, cilantro, and basil.
PREPARATION
Remove the tops/bottoms/skins/stems from any vegetables you are preparing (avoid vegetables like Brussels sprouts, broccoli, or cauliflower as they will add a bitter taste to your stock) and place them in a ziplock bag – they can stay frozen up to 6 months.
Continue like this until bag is full.
Dump bag into pot and fill ¾ of the pot (or until scraps just start to float) with water.
Bring water to a boil and then let it simmer for at least 30 minutes.
Strain water out of stock.
Refrigerate stock up to 4 days, or freeze up to 3 months.
