Tomato Mirepoix Soup

Tomato Mirepoix Soup

I’ve been experimenting with some new (to me) cooking techniques lately and discovered “Aromatics.” Aromatics are a mix of vegetables and herbs sautéed in a bit of oil or fat and are used as the base for many dishes. They are perfect for making rich, flavorful soups. Every culture has their own version and for this recipe I used the French variant called “Mirepoix.”

Mirepoix in the cast iron

Mirepoix is a mixture of celery, carrot, and onion that is sauteed in oil with herbs until the onion is translucent. In this, I used olive oil and a blend of dried basil, rosemary, thyme and oregano. When the onions were almost done I added two minced cloves of garlic. Adding the garlic too soon will burn it and give it a bitter taste. As this was sauteeing, I blended up some tomato from last year’s garden harvest that we keep frozen for use in the winter.

Ideally you should blanche tomato before freezing so that the skins can be removed easily. However, these tomatoes were roughly chopped and made into a chunky sauce before freezing flat in gallon size bags. I used half from the bag for this recipe. Roughly 5 cups of chopped tomato. A large can of puréed tomato will work for this. I’ve added about 2 cups of water to the puréed tomato to fill the pot about 1/3 the way up.

Once the Mirepoix is ready just add it directly to the pot. Add a tablespoon of paprika, teaspoon of cayenne, and a couple bay leaves then salt to your preference. I used about a tablespoon of salt for the whole pot. Let this simmer on low heat with the lid on for about 30 minutes for all the flavors to blend. Taste to see if it needs more salt. I try to use as little as possible if I can help it.

Serve with a sprinkle of fresh grated peccorino cheese and a dash or two of pepper. Grilled cheese sandwiches are optional.
