Easy Steps to the Most Delicious Instant Pot Tomato Florentine Soup to Make Tonight

I love this homemade Instant Pot Tomato Soup.  A nice warm bowl of tomato soup is such a great comfort food, and this recipe doesn’t disappoint.  It’s full of absolutely delicious flavors and spices. It’s a little sweet and creamy and crunchy with the grilled cheese croutons. You’ll be in soup heaven! 

This soup is easy to make, comes together quickly, and everyone will be glad you made it.  It’s perfect for weekend lunches, or dinner on those chilly nights. It is also freezer friendly with one change so take note of that awesome option!! We promise, this one will be a favorite!

So let the rain and/or snow fall, pull on the fuzzy socks and let’s make a batch of this amazing soup. I can practically hear the fire crackling now! 

🍓 Ingredients

Enjoying a hot bowl of this amazing soup is the comforting meal you have been needing. Let’s talk a little bit about a few of the ingredients:

Seasonings and Herbs: We use a combination of parsley, thyme, oregano, sugar, coarse garlic salt, salt, and pepper in this soup. It’s an incredible group of ingredients that you can’t go wrong with.

Veggies: This tomato florentine soup has celery, spinach, and stewed tomatoes. They are perfect together, and you can’t help but want a second bowl every time you taste it.

Grilled Cheese Crouton: One of my favorite ingredients is the homemade grilled cheese croutons. They are made with butter, olive oil, garlic salt, garlic, bread, and cheese.

🍽️ Instructions 

This is one of the few recipes that we make that have more than just a couple ingredients! Hold onto your hats though as it is worth it.

Step one: In the bottom of the Instant pot with the setting on ‘SAUTE’ melt one tablespoon of butter. Add chopped onion and celery and saute until golden brown.

Step two: Add the finely chopped Spinach and parsley. Cook until wilted and a little brown.  Sprinkle with a little salt and pepper.  

Step three: Turn SAUTE setting off, and add the fresh thyme.  

Step four: Stir in chicken broth, stewed tomatoes, tomato puree, and tomato paste. Stir well until the tomato paste is melted into the soup.  Add water, and stir.  

Step five: Add the Italian seasoning, oregano, brown sugar, coarse ground garlic salt, seasoned salt and pepper.  Stir well to blend all ingredients. Place the lid on the Instant Pot and make sure the pressure valve is set to SEAL.  

Step six: Press the SOUP setting on your Instant pot, and let the soup cook.  When the Instant pot is done, it will beep. Let the soup sit in for another ten minutes and do a quick release by turning the pressure valve to VENT. Make sure you use a pot holder or oven mitt to turn the valve so you don’t burn yourself with the steam. When all the pressure has been released, and the float valve drops down, remove the lid and stir.  

Step seven: Add the cream and stir well. Add the minced garlic and stir. 

🍲 How to Make Croutons

While the soup is cooking, make the croutons. You can alternatively, make our Homemade Croutons as well. Both work great for this recipe.

Step one: In a bowl, combine the softened butter, olive oil, garlic salt, and smashed garlic.  Blend all together, and spread on one side of each slice of bread.  

Step two: In a skillet, place the bread, buttered side down, and sprinkle cheese on top.  Place another piece of bread, buttered side up on top of the cheese.  

Step three: Cook the grilled cheese until golden brown on both sides.  Remove from skillet, and place on a cutting board. Cut the grilled cheese into large crouton-sized pieces, and serve on the side.

🍴Can You Freeze This Soup

Yep! There is one caveat though.  If you know you are going to freeze it, I would leave out the cream.  It is easy enough to add the cream when you defrost and reheat it later.  Sometimes, the cream just doesn’t freeze that well.  

Place the cooled soup in gallon sized freezer safe Ziploc bags. Press the air out and lay flat in the freezer on sheet pans until frozen. Make sure to label them.

To defrost, take out the night before and heat up in a stove top pot (and add the cream you left out!) and serve.
