This delicious Parmesan tomato soup is made with just seven ingredients for a simple yet flavorful recipe! Transform a few basic pantry staples into a tasty bowl of soup in minutes.

Is there anything better than a warm bowl of tomato soup? This Parmesan tomato soup recipe uses canned tomatoes and just a few pantry staples, so you can have a fresh bowl of tomato soup in no time. I love the salty Parmesan in this recipe and it’s the perfect soup to serve with a slice of crusty bread or a grilled cheese sandwich!

To make this Parmesan tomato soup, you’ll need:

Olive oil
Onion (white or yellow is fine)
Canned tomatoes (whole or diced)
Crushed red pepper flakes
Parmesan cheese
Garlic salt (or garlic powder and salt)

Substitution Ideas

If you don’t have diced tomatoes, you can use whole canned tomatoes or fresh tomatoes. If substituting fresh tomatoes, you’ll need about 3 cups of chopped tomatoes.
I like crushed red pepper for a spicy flavor but if you don’t like spicy food, simply leave it out or substitute with a pinch of black pepper for a milder flavor.
I like to use low sodium “not chicken” style broth, which tastes like chicken broth but is vegetarian. You can substitute any type of vegetable broth you like.

Serving Suggestions

Obviously, this tomato soup is perfect with a grilled cheese! But you can also try it with a hearty kale salad or a grilled halloumi sandwich. If you’re looking for a lower-carb meal, try serving this soup with an easy halloumi salad! It has the savory flavor of a grilled cheese but it’s served on a bed of greens and veggies instead of bread!

Tips for Blending Hot Soup

Blending soup is easiest with an immersion blender. This stick-style blender can be used directly in the pot. You can blend until you get your desired consistency. If you don’t have an immersion blender, let the soup cool slightly and carefully transfer to a blender. When blending, ensure that steam can escape from the lid. Do not attempt this with a bullet style blender!
