  • 1 cup finely diced carrots
  • 1 cup finely diced onions
  • 1 tsp dried oregano or 1 T fresh oregano
  • 1 T dried basil or 1/4 cup fresh basil
  • 4 cups chicken broth
  • ½ bay leaf
  • ½ cup flour
  • 1 cup Parmesan cheese
  • ½ cup butter

  • 1 tsp salt
  • ¼ tsp black pepper

Tomato Basil Parmesan Soup Instructions

1. Add tomatoes, celery, carrots, chicken broth, onions, oregano, basil, and bay leaf to a large slow cooker.

Add another 3 cups and stir until smooth. Add all back into the slow cooker. Stir and add the Parmesan cheese, warmed half and half, salt and pepper. Add additional basil and oregano if needed (the slow cooker does a number on spices and they get bland over time, so don’t be afraid to always season to taste at the end).

Incredible Tomato Basil Soup Recipe Hack

Did you catch it? Did you see the slight wrinkle in the recipe process that is going to put your tomato basil soup in the Soup Hall Of Fame? The simple step of creating a butter-based tomato roux does two things: 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.

Tomato Basil Recipe Hack Steps

1. Melt ½ cup of butter over low heat.

2. Once melted, slowly whisk in ½ cup of flour (stir constantly for 5-7 minutes)

3. Slowly stir in 1 cup of hot soup, continuing to stir

4. Add another 3 cups of soup (one cup at a time) to the roux stirring constantly.

5. Allow everything to simmer over medium heat for another minute, then add back into the soup.

Can You Freeze Tomato Basil Soup? How Long Will Tomato Soup Last?

One of the other 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 in multiple containers.

There are two effective ways to effectively freezing 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 is to use quart sized freezer bags (heavy duty Ziploc bags are the best). Ladle the soup into each bag about ⅔ full. Next, press as much air as possible out of the freezer bag. Seal tightly. Label each bag with the day’s date and lay flat so more surface area of the soup 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. The better the freezer bag you use, the better it will seal and protect your soup from the freezing process. The lesson: Don’t go cheap with freezer bags.

Freezing Tomato Basil Soup Method #2

The plastic bag in the freezer is a great way to freeze a lot of soups. Another effective way to freeze tomato basil 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. Use the same steps in method one for thawing.

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

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 bisque is a very popular type. Below we highlight the major differences between the two.

tomato soup vs tomato bisque

Tomato Soup

For the most part, tomato soup is a more liquidy food served hot or warm. They include ingredients such as vegetables, stock, water, and proteins such as beef or chicken. 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 in for chicken or other proteins.

Tomato Bisque

For tomato bisque, you’ll usually desire a smoother, creamiers 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 enhance the creamier texture. There are similar ingredients with a bisque compared to just soup, but usually a heavy cream is added for textural purposes, but the added fat from the cream augments the flavor of the ingredients because of its elevated levels of fat.
