5-Ingredient Pantry Tomato Soup

Last updated on August 9th, 2025

This easy 5-ingredient pantry tomato soup is herby, tangy and so rich and vibrant you’d never know it’s made with only a handful of pantry staples. A healthier take on a comfort food favourite, it’s both dairy and gluten free and ready in under 30 minutes!

We grow and preserve our own tomatoes during the summer months, and to be honest I find the options available to us here in winter often taste woody and bland. Canned or preserved tomatoes, however, are a great option. Not only are they both cost effective and readily available, they’ve also been harvested at their peak.

Here’s everything you’ll need to make this 5-ingredient pantry tomato soup

• 1 large white onion
• 2 800 ml cans whole or diced tomatoes or 15-20 whole fresh tomatoes
• 4 cups broth of your choice
• 4 garlic cloves
• 2 tablespoons Italian seasoning blend (see note below to make your own)
• Kosher or fine sea salt and freshly ground pepper
• Fresh thyme leaves to garnish

You can use vegetable, chicken or bone broth for added nutritional value, they will all result in a delicious soup. To make this soup using whole, fresh tomatoes like I use in my Quick Homemade Tomato Sauce or veggie and protein-packed Minestrone Soup, see the ingredient list below.

Served alongside a toasty, melty grilled cheese, this simple, homemade 5-ingredient pantry tomato soup makes the coziest snow day lunch!

Notes

Italian seasoning blend: Both finely chopped fresh and/or dried herbs work well in this recipe. To make your own blend, in a small dish or measuring cup stir together 2 teaspoons basil, 2 teaspoons oregano, 1 teaspoon rosemary, 1 teaspoon thyme and 1 teaspoon marjoram.

Storage: Leftovers can be kept in the refrigerator in a well-sealed container for up to 5 days or frozen for up to 3 months. To reheat, thaw to room temperature and bring to a simmer in a saucepan adding a little more broth if needed to reach desired consistency.
