Ingredients
List of Required Ingredients
- 2 cans (28 oz each) crushed tomatoes
- 1 medium onion, finely diced
- 4 cloves garlic, minced
- 1 teaspoon dried basil
- 1 teaspoon granulated sugar
- 4 cups vegetable broth
- 1 cup heavy cream or coconut cream

This creamy tomato basil soup is a delight to make. I love how simple it is to gather the ingredients. Canned crushed tomatoes form the base, providing a rich and tangy flavor. You’ll need one medium onion. Finely diced, it adds sweetness and depth. Four cloves of garlic bring a wonderful aroma and taste.
Dried basil gives a nice herbal note. I always add a teaspoon of granulated sugar. This helps balance the acidity of the tomatoes. For the broth, use four cups of vegetable broth. It enhances the soup's flavor without overpowering it.
The cream is what makes it truly creamy. You can use heavy cream for richness or coconut cream for a dairy-free option. Season to taste with salt and freshly cracked black pepper. Finally, fresh basil leaves will garnish each bowl, adding a pop of color and flavor.
These ingredients come together to create a comforting and delicious soup. Just imagine how great your kitchen will smell as it cooks!

Presentation Ideas

Pro Tips

- Perfect Pairing: This creamy tomato basil soup pairs beautifully with grilled cheese sandwiches or garlic bread for a classic comfort meal.
- Adjust Thickness: If you prefer a thicker soup, reduce the vegetable broth by one cup or add more heavy cream to achieve your desired consistency.

Variations
Dairy-Free Option
You can make this soup dairy-free by using coconut cream or almond milk. Coconut cream adds a rich, creamy texture without dairy. Almond milk offers a lighter touch. Both options keep the soup tasty and smooth.
Add-Ins for Varied Flavor
To change up the flavor, consider adding roasted red peppers or spinach. Roasted red peppers bring a sweet and smoky taste. Spinach adds freshness and color. You can also top your soup with croutons or cheese for a richer taste. Croutons give a crunchy contrast, while cheese melts into the soup for creaminess.
Spice It Up
If you like heat, add red pepper flakes. They provide a nice kick that wakes up your taste buds. For a bright flavor, incorporate lemon zest. The zest adds a fresh, citrusy note that balances the soup’s richness.
