Just make sure to avoid cooking scallions for too long as they are quick and easy to burn.
Chives
Chives are also great alternatives to onions, especially if what you are looking for is a substitute that has a milder taste. Chives taste like onion, though, this taste is still not as strong as the latter.

One cup of fennel bulb (chopped) is enough to substitute one cup of onion (chopped).

To bulk up the dish again after removing onion, add chopped veggies, like sweet potatoes and tomatoes.
Celery
Another famous onion substitute is celery. It is a commonly used vegetable in a lot of dishes because of its earthy peppery taste and crispy texture.
You will surely find the long stalks of celery useful not only in soups but also in stews, sauces, casseroles, stocks, salads, and stir-fries. They work even better if you pair them with bell peppers and carrots.
The leaves of celery are also known for having a harder texture and stronger taste compared to the stalks. You are assured of their ability to improve the flavor of your soups and other dishes.

If you don’t have onions on hand, just look for carrots in your kitchen. They will serve as great alternatives to the onions required in your soups, sauté, and stir-fried recipes.

Cabbage
Another great yet cheap replacement for onions in your soup recipes is cabbage. The taste of cabbage may not be that close to onions but you can still expect it to work well in recipes that require the latter.
