Making soup is not only incredibly satisfying, it’s also ridiculously easy. At its most basic, you start with water, add some means of making it taste better-usually meat, poultry, fish, or aromatic vegetables, along with seasonings-and finish with a few (or a slew of) vegetables and/or grains.

Really, it’s almost impossible to make “bad” soup. If you start with good ingredients-and you should-the results are likely to be great, because every bit of flavor remains in the part you eat. When you’re done, you have an ideal first course for entertaining or weeknight suppers or an easy course to build a meal around.
The process need not be elaborate or time consuming, and it rarely requires precision. There’s little measuring and a lot of room for improvisation; even the timing is flexible. In fact, most soups are simple and forgiving, and many take less than thirty minutes to prepare; if one takes longer, most of the cooking time is unattended. And almost every stock and soup can be made ahead.
There are a few issues to consider in soup making:
Preparing foods for soup: Cutting vegetables or other ingredients to about the same size allows them to all cook at pretty much the same rate; you don’t want your carrots tender while your potatoes are still hard. And using small pieces allows you to eat soup elegantly, without cutting in the bowl or cramming too-large pieces of food into your mouth.
Using leftovers in soup: One of my first cooking teachers made cream-of-something-or-other almost every night with leftover vegetables. She rinsed the leftovers with boiling water, combined the vegetables with stock and seasonings, puréed, and reheated, sometimes with cream, sometimes with milk or yogurt, sometimes with nothing.

Almost any leftover whose flavor does not conflict with the basic seasonings of your soup is fair game: pasta, rice, bread, meat, fish, poultry, vegetables - even mashed potatoes, which can blend in nicely.
Heating stock for use in soup: Most soups begin by cooking some meat or vegetables, then adding stock or water. If you heat the stock or water while you prepare the solid ingredients, you will cut your cooking time by as much as ten or fifteen minutes.
Puréeing soup: Upright and immersion blenders can purée almost any soup in an instant. (A hand-cranked food mill is not a ton of work, but it’s not nearly as fast.) If the purée is too thick, stir in some water or half-and half, which will add flavor, enhance texture, and thin the soup all at the same time.
Incidentally, guilt factor aside, heavy cream is a sensational thickener, adding wonderful flavor and silken texture. And you don’t need much-1/2 cup or even less is usually enough for 6 cups of soup.
Adding pasta or rice to soup: Rice or pasta add body, flavor, and variety to soups, but they’re best cooked in separate water, because they absorb so much water and give off so much starch that cooking them directly in the soup changes the character entirely. (There is nothing wrong with this, of course, but you should be aware of it.)

Storing soup: Many soups can be made in advance, or at least partly so (I’ve noted the best time to interrupt cooking when there is one), and freeze brilliantly for a month or more, so there’s rarely a reason not to double or even quadruple a given recipe to reserve some for another time.
Generally, it’s best not to freeze or even refrigerate a soup once you’ve added starches like rice and pasta. Since they continue to absorb water even during storage, they break down, becoming soft and thickening the soup unnecessarily (of course if you like these qualities, go right ahead). Nor should you freeze soups made with dairy, which are likely to curdle when reheated
