Step-by-Step Instructions
Preparation Steps for Slow Cooker Setup
First, gather all your ingredients. You will need two cans of crushed tomatoes, one chopped onion, and three minced garlic cloves. Measure three cups of vegetable broth and set aside a teaspoon of dried oregano. Don’t forget the teaspoon of sugar, salt, and pepper for taste. You should also prepare a cup of heavy cream or coconut milk and a cup of chopped fresh basil. Lastly, grab two tablespoons of olive oil.
Next, take your slow cooker and pour in the crushed tomatoes. Add the chopped onion and minced garlic. Stir in the vegetable broth, dried oregano, sugar, salt, and pepper. Then, drizzle in the olive oil. This will help bring out the flavors.
Cooking Times: Low vs. High Settings
Now, it’s time to cook your soup. You can choose between two settings: low or high. If you pick the low setting, let the soup cook for 6 to 8 hours. This slow method allows the flavors to blend well. If you’re in a hurry, use the high setting and cook for 3 to 4 hours. Either way, the soup will be tasty!
Blending Techniques for Desired Texture
After cooking, you need to blend your soup. For a smooth texture, use an immersion blender right in the slow cooker. Blend until the soup is creamy and rich. If you like some chunks, blend only half the soup. This adds texture and makes each spoonful interesting. Finally, stir in the heavy cream or coconut milk and the chopped basil. Let it sit on low heat for 15 to 20 minutes to combine all the flavors. Enjoy your creamy tomato basil soup!
Tips & Tricks
How to Enhance the Flavor Profile
To boost the taste of your creamy tomato basil soup, think about adding more herbs. Fresh or dried thyme, for example, pairs well with tomatoes. You can also add a splash of balsamic vinegar for depth. A pinch of red pepper flakes can add a gentle kick. Don't forget to taste your soup before serving. Adjust the salt and pepper as needed for the best flavor.
Storage Tips for Leftover Soup
If you have extra soup, store it right! Let it cool, then place it in a container. Use airtight containers to keep it fresh. This soup can last in the fridge for about 3 to 4 days. If you want to store it longer, consider freezing it. Just make sure to leave some space in the container for expansion.
Making Ahead: Freezing and Reheating Instructions
Freezing your soup is easy and smart! Pour the cooled soup into freezer bags. Lay them flat for easy stacking. When you want some, take it out and thaw it in the fridge overnight. To reheat, warm it on the stove over low heat, stirring often. If the soup seems thick, add a bit of broth or water to adjust the texture. Enjoy your delicious soup anytime!
Variations
Spicy Tomato Basil Soup Twist
Want to add some heat? You can easily spice up your creamy tomato basil soup. Just add a pinch of red pepper flakes or a chopped jalapeño. This small change brings a kick that pairs well with the creamy base. If you want more spice, try adding a splash of hot sauce before serving. This twist keeps things exciting and warms you up on a cold day.
Adding Vegetables for Texture and Nutritional Boost
You can boost the nutrition and texture of your soup by adding veggies. Carrots, bell peppers, or zucchini work great. Dice them small so they cook well. Add these vegetables at the start with your other ingredients in the slow cooker. They will soften and blend beautifully with the tomatoes. This way, you get extra flavor and vitamins in every bite.
Pairing Suggestions: Best Sides to Serve

If you want something crunchy, try toasted bread or crackers. These sides help balance the soup's creaminess. You can mix and match to find your perfect pairing!
Storage Info
Proper Containers for Refrigerating Soup
To keep your creamy tomato basil soup fresh, use airtight containers. Glass jars work well. They let you see the soup inside. You can also use plastic containers, but ensure they are safe for food. Label the containers with the date. This helps you track freshness.

You can store creamy tomato basil soup in the fridge for up to 5 days. Make sure it cools before sealing it in a container. If you want to keep it longer, consider freezing it. Frozen soup lasts about 3 months. Just remember to leave some space in the container for expansion.
Reheating Tips for Best Results
When you reheat your soup, use a pot on the stove. Heat it over medium heat for even warming. Stir often to avoid sticking. If the soup seems too thick, add a splash of broth or water. You can also use a microwave. Heat in short bursts and stir in between.
