Ingredients You’ll Need
- 2 tablespoons olive oil
- 1 medium yellow onion, chopped
- 2 cans crushed tomatoes, 28 ounces each
- 2 cups vegetable broth
- ½ cup fresh basil leaves, loosely packed
- ½ teaspoon salt, plus more to taste
- ¼ teaspoon black pepper, plus more to taste
For serving, optional but helpful:
- Grilled cheese sandwiches
- Croutons
- Crackers
- Extra fresh basil
- Drizzle of olive oil
The five main ingredients in this recipe are olive oil, onion, crushed tomatoes, vegetable broth, and fresh basil. Salt and pepper are included as simple seasonings because they help bring the tomato flavor forward without making the soup complicated.
Crushed tomatoes are a good choice because they already have a smooth texture and cook down nicely. They give the soup body, color, and that rich tomato base without needing fresh tomatoes or a long simmer.
Fresh basil makes the soup taste bright and homemade. It softens into the tomatoes and adds a gentle herby flavor that keeps the soup from tasting flat.
Vegetable broth helps loosen the soup and gives it a savory base. You can use low-sodium broth if you want more control over the salt, especially when cooking for kids.
The onion may seem simple, but it makes a big difference. Once it softens in olive oil, it adds natural sweetness and helps balance the acidity of the tomatoes.
Pro Tips
Let the onion cook until soft before adding the tomatoes. This gives the soup a sweeter, smoother flavor and keeps the onion from tasting sharp.
Use good canned crushed tomatoes if you can. Since this soup has only a few ingredients, the tomato flavor really matters.
Blend the soup until it is as smooth as your family likes it. Some people love a silky soup, while others prefer a little texture.
Add the basil near the end of cooking. Fresh basil can lose its bright flavor if it simmers too long, so adding it late keeps the soup fresh.
Taste before serving and adjust the salt slowly. Canned tomatoes and broth can vary, so it is better to season a little at a time.
For kids, serve the soup with something fun for dipping. Grilled cheese strips, crackers, or toasted bread cubes make the meal feel more filling and easy to enjoy.
Tools You’ll Need
- Large soup pot or Dutch oven
- Cutting board
- Sharp knife
- Measuring spoons
- Measuring cups
- Wooden spoon
- Can opener
- Immersion blender
- Ladle
- Soup bowls
A large soup pot or Dutch oven gives the tomatoes enough room to simmer without splattering too much. It also helps the onion cook evenly before the liquid ingredients are added.
An immersion blender is the easiest tool for blending the soup right in the pot. It saves time and keeps cleanup simple, which is helpful on busy days.
If you do not have an immersion blender, a regular blender can also work. Just blend in small batches, leave space for steam to escape, and be careful because hot soup expands quickly.
A wooden spoon is useful for stirring the onions and scraping the bottom of the pot. This helps prevent sticking and keeps all the flavor in the soup.
Substitutions and Variations
Use Chicken Broth Instead
Chicken broth can be used in place of vegetable broth if that is what you have on hand. It gives the soup a slightly richer flavor while keeping the recipe simple and familiar.
Make It Creamier
Stir in ¼ cup heavy cream, half-and-half, or coconut milk after blending. This makes the soup softer and creamier while still keeping the tomato and basil flavor at the center.
Add a Little Heat
Add a pinch of red pepper flakes while the onion cooks. It gives the soup a gentle warmth without changing the basic flavor too much.
Make It Heartier
Serve the soup with cooked pasta, rice, white beans, or cheese tortellini. These add-ins turn a light bowl of soup into a more filling family meal.
Use Dried Basil in a Pinch
If you do not have fresh basil, use 1 to 1 ½ teaspoons dried basil instead. Add it with the tomatoes so it has time to soften and flavor the soup.
Make Ahead Tips
5-Ingredient Tomato Soup with Basil is a great recipe to make ahead because the flavor becomes even smoother after it rests. You can prepare the full pot up to 3 days in advance, let it cool, and store it in an airtight container in the refrigerator.
If you want to prep only part of the recipe, chop the onion and wash the basil ahead of time. Keep the onion in a sealed container in the refrigerator and wrap the basil gently in a paper towel so it stays fresh.
You can also freeze this soup after blending. Let it cool completely, then portion it into freezer-safe containers so you can thaw only what you need for quick lunches or simple dinners.
For the best fresh basil flavor, you can stir in a few extra chopped basil leaves after reheating. This gives the soup a brighter taste, especially if it has been stored for a few days.
Instructions
Step 1: Soften the Onion
Place a large soup pot or Dutch oven over medium heat and add the olive oil. Once the oil is warm, add the chopped yellow onion and stir to coat it.
Cook the onion for 6 to 8 minutes, stirring often, until it looks soft and lightly golden. It should smell sweet and mellow, not sharp or browned.
Step 2: Add the Tomatoes
Pour the crushed tomatoes into the pot with the softened onion. Stir well, scraping the bottom of the pot so the onion mixes fully into the tomatoes.
Let the tomatoes warm for 2 to 3 minutes before adding the broth. This helps the tomato flavor deepen a little and gives the soup a stronger homemade taste.
Step 3: Pour in the Broth
Add the vegetable broth to the pot and stir until the soup looks evenly combined. Bring the soup to a gentle simmer over medium heat.
Once it starts to bubble softly, lower the heat to medium-low. Let it simmer for 15 to 20 minutes, stirring now and then so nothing sticks to the bottom.
Step 4: Season the Soup
Stir in the salt and black pepper. Taste carefully, then add a little more salt if the soup needs more flavor.
The amount of salt you need can change depending on the tomatoes and broth you use. Start small, because it is easier to add more than to fix a soup that tastes too salty.
Step 5: Add the Fresh Basil
Add the fresh basil leaves during the last 2 to 3 minutes of simmering. Stir them into the hot soup until they soften and turn darker green.
Adding basil near the end helps keep its flavor fresh and gentle. If it cooks too long, the flavor can become dull, so keep this step quick.
Step 6: Blend Until Smooth
Turn off the heat and blend the soup with an immersion blender until it reaches your preferred texture. Blend for 1 to 2 minutes for a smooth soup, or stop earlier if your family likes a little texture.
If using a regular blender, carefully blend the soup in small batches. Leave room for steam to escape, hold the lid with a towel, and pour the blended soup back into the pot.
Step 7: Warm and Adjust
Place the blended soup back over low heat for 2 to 3 minutes if needed. Stir and taste again, adding more salt, pepper, or a small drizzle of olive oil if you want a richer finish.
The soup should taste bright, smooth, and balanced. If it tastes too acidic, let it simmer a few extra minutes or add a small pinch of sugar.
Step 8: Serve
Ladle the hot tomato soup into bowls. Add extra basil, croutons, crackers, or a drizzle of olive oil if you like.
Serve it with grilled cheese, toast, or a simple salad for a complete meal. The soup is best warm, smooth, and fresh from the pot.
Serving Suggestions
Serve this tomato soup with grilled cheese sandwiches cut into strips for easy dipping. It is a simple pairing that makes the meal feel cozy and filling, especially for kids.
A warm piece of crusty bread is also a good match. The bread soaks up the smooth tomato broth and makes the bowl feel more satisfying.
For lunch, pair the soup with a simple green salad or a turkey sandwich. The soup adds warmth while the sandwich or salad keeps the meal balanced.
You can spoon the soup into small mugs for an easy after-school snack. Add crackers on the side so kids can dip and scoop without needing a big meal.
For a heartier dinner, serve it with cooked pasta, cheese tortellini, or white beans stirred into each bowl. These add-ins keep the base recipe simple while making it more filling.
A small sprinkle of Parmesan or a swirl of cream can make the soup feel a little richer. Keep toppings on the side so everyone can choose what they like best.
Leftovers and Storage
Store leftover 5-Ingredient Tomato Soup with Basil in an airtight container in the refrigerator for up to 4 days. Let the soup cool before closing the container and placing it in the fridge.
Reheat it gently on the stove over medium-low heat, stirring often until warm. You can also microwave it in a covered bowl in 45-second bursts, stirring between each one.
If the soup thickens after chilling, add a splash of broth or water while reheating. Stir until it loosens back into a smooth, spoonable texture.
This soup also freezes well for up to 3 months. Store it in freezer-safe containers, leaving a little space at the top because soup expands as it freezes.
Thaw frozen soup overnight in the refrigerator before reheating. For the freshest flavor, add a few torn basil leaves after warming.

Recipe FAQ
Can I use whole canned tomatoes instead of crushed tomatoes?
Yes, whole canned tomatoes can work well in this soup. Crush them with your hands or a spoon before adding them to the pot. Since they are chunkier, you may need to blend the soup a little longer for a smooth texture.
Can I make this tomato soup without an immersion blender?
Yes, you can use a regular blender instead. Blend the soup in small batches and be careful with the steam because hot liquid expands. You can also leave the soup slightly chunky if you do not mind more texture.
Can I use dried basil instead of fresh basil?
