We eat a lot of the red pepper tomato soup they sell at Costco. It’s a quick dinner (usually accompanied by some sourdough grilled cheese *drool*) and the kids all love it.

I was inspired by this and wondered if I could hack this recipe and create a delicious twist on a tomato soup without using fresh tomatoes. Or even canned tomatoes!

This soup is EASY and requires very little chopping. Just an onion! You can have it done in a flash and I’ll show you how to make it dairy free, too.

Ingredients for roasted red pepper and tomato soup: jarred roasted red peppers, tomato paste, milk, onion, garlic, honey, and butter.

Roasted Red Pepper Tomato Soup Ingredients

  • Butter
  • Onion – This is the only thing you’ll need to chop!
  • Garlic
  • Jarred Roasted Red Peppers
  • Tomato Paste
  • Honey – Use another type of sweetener if you like.
  • Milk – See note below
  • Salt
  • Garnishes – Optional, but you can add some cheese (feta, goat cheese, and Parmesan are especially good), pesto, or a spicy condiment to add some heat.

How to make this tomato soup dairy free

To make this soup dairy free use coconut oil or avocado oil in place of the butter and non-dairy milk. If you use non-dairy milk that isn’t sweetened you may need to add a little extra sweetener to balance the acidity in the soup.

How to Make Roasted Red Pepper and Tomato Soup

  1. Saute the chopped onion in the butter for several minutes until it turns golden. Don’t skip on this step since it creates extra sweetness the soup needs! Throw the garlic in there, too, and stir in the tomato paste.
  2. Add the drained red peppers, milk, honey, and salt. Cook until the soup is steamy and hot but not boiling.
  3. Blend the soup up using an immersion blender or in a countertop blender.
  4. Taste and adjust the salt and sweetener as needed.
  5. Serve!

Serving Roasted Pepper and Tomato Soup

I added some goat cheese and chili crunch to my soup, but you can add any cheese, pesto, or spicy condiment you like! Or get creative with your own garnishes.

What goes well with tomato soup?

This soup stands alone well as a light meal, but if you need to round it out with something here are a few ideas. We love it with some sourdough grilled cheese sandwiches, but here are a few lighter ideas for you:

Fresh, green salad: My Syrian Salad, Avocado Salad with Lettuce, or my Spring Mix Salad with Raspberry Vinaigrette are all great pairings.

Bulk it up: Add in some leftover grilled chicken, steak, or shrimp. Or some leftover cooked grains, like rice, quinoa, or farro.

How to Store Red Pepper Tomato Soup

Chilled: Store in an airtight container or covered saucepan in the fridge for up to a week.

Frozen: Transfer cooled soup to a freezer-safe container and freeze for several months.

I like these freezer safe deli containers on Amazon. They’re great for freezing soups, broths, and general leftover storage in the fridge since they stack well.

Roasted Red Pepper and Tomato Soup Recipe FAQs

How do you get the bitter taste out of red pepper soup?

Sweetness does the trick. Browning the onion in the beginning adds natural sweetness to the soup as well as the honey. I highly recommend using at least a little sweetener — any type you like.

How do you tone down red peppers in soup?

Adding the tomato paste and balancing out the red pepper with some sweetness helps to tone down its flavors.

Yield: Serves 4
Prep Time: 15 minutes
Cook Time: 20 minutes
Total Time: 35 minutes

Want to make a delicious tomato soup but don't have fresh tomatoes? I've got you. Using just a few pantry staples, you can have this deliciously simple red pepper tomato soup on the table in under 30 minutes without a tomato run!


  • 4 Tablespoons butter
  • 1 medium onion, peeled and chopped roughly
  • 6 whole garlic cloves
  • 3 Tablespoons tomato paste
  • 1 16-oz jar roasted red peppers, drained (see note)
  • 2 cups milk
  • 2 Tablespoons honey
  • 1 1/2 teaspoon salt


  1. Melt butter in a large saucepan over medium-high heat. Add chopped onion and cook for 6-8 minutes until the onions turn light golden brown. Add the whole garlic cloves and cook for another 2-3 minutes.
  2. Stir in the tomato paste and cook for another minute or so. Add the drained red peppers, milk, honey, and salt. Warm the soup until it's hot and steamy.
  3. Blend with an immersion blender or with a countertop blender until smooth.
  4. Taste, and add a little extra honey or salt if you think it needs it.
  5. Ladle into bowls and serve.


  1. The roasted red peppers I used have an undrained weight of 16 ounces. The drained weight is a little less.
  2. Freel free to use any kind of milk here. If you use unsweetened almond milk, you may need to add a little extra honey to balance the sweetness since dairy milk is sweeter.
  3. I like to top my with feta and chili crunch! Any kind of strong, salty cheese would be good. Pesto would also be a great mix-in.
