What’s the difference between Tomato Soup and Tomato Bisque?

I used to think bisque was just a fancy way of saying soup, but it turns out, there are a few slight differences between tomato soup and tomato bisque. Traditionally, a bisque was a creamy, shell-fish based soup that was thickened with either bread crumbs or cream. Since then, the term bisque has transitioned to include anything that is primarily thick and creamy. Tomato is a very popular type of bisque. Below we highlight the major differences between soups and bisques.

tomato soup vs tomato bisque

Tomato Soup

For the most part, tomato soup is a more liquidy food served hot or warm. Soup in general often includes ingredients such as vegetables, stock, water, and proteins such as beef or chicken. It can be smooth, or chunky with ingredients. Typically, soups are not thickened, but some recipes call for this method. Tomato soup can be made with carrots, tomatoes, garlic, basil, onions, celery, and some opt for chicken or other proteins.

Tomato Bisque

On the other hand, tomato bisque is usually a smoother and creamier type of soup that includes more herbs and spices to raise the level of seasoning. Ingredients are usually minced prior to cooking and in a lot of scenarios, chef’s will puree the soup to ensure a creamy texture. While bisque and soup have similar ingredients, bisque usually has the addition of a heavy cream that enhances the texture and elevates fat levels, which in turn augments the flavor of the ingredients.

Can You Freeze Tomato Basil Soup?

One of the hidden benefits of this tomato basil soup recipe is that it freezes extremely well. So that means you can make this soup and enjoy a warm meal over and over again, especially if you store it in multiple containers.

There are two ways to effectively freeze tomato basil soup. Regardless of the way you choose, make sure you completely cool the soup before putting it into a container.

Freezing Tomato Basil Soup Method #1

The first way to freeze soup is to use quart sized freezer bags (heavy duty Ziploc bags are the best). Ladle the soup into each bag until it’s about ⅔ full. Press as much air as possible out of the freezer bag before sealing it tightly. You’ll want to label each bag with the day’s date and lay it flat in the freezer. Not only does this save room, but it makes it so more of the soup’s surface area is exposed to the cold temps. When thawing, put the frozen soup bag in the refrigerator overnight. Reheat in the microwave or in a pot. Using a high quality freezer bag will help seal and protect your soup during the freezing process. The lesson: Don’t go cheap with freezer bags.

Freezing Tomato Basil Soup Method #2

Another effective way to freeze soup is to use these plastic storage containers with airtight lids. Fill each container with soup, leaving at least one inch of space between the soup and the lip of the container. To thaw and serve, use the same steps in the previous method.

How Long Will Tomato Soup Last?

Cook once, enjoy twice. That’s my motto. You can keep this soup on hand for a long time. If you freeze it using one of the techniques above, you can plan on it lasting around six months in the freezer.

Incredible Tomato Basil Soup Recipe Hack

One more thing before we get to the recipe. There is one little trick that takes this tomato basil parmesan soup from good to qualifying for a spot in the Soup Hall of Fame. The simple step is creating a butter-based tomato roux. It does two things for the soup: 1) It thickens your tomato soup and 2) the extra fat in the butter (don’t use margarine or other butter substitutes) augments the flavor of all the ingredients. How? Fat makes food taste better because the fats are able to dissolve and concentrate flavors in ingredients. So no matter how much you’re tempted, don’t skip this step.

And now for the recipe. You can see the Tomato Basil Parmesan Soup recipe below, or you can view and download printable recipe cards HERE. Enjoy!
