Ingredient Notes

• Fresh tomatoes: I always use ripe, in-season tomatoes—it makes a huge difference in flavor compared to canned!
• Basil: Don’t skip the fresh basil! It gives the soup that classic tomato basil soup aroma that everyone loves.
• Cream: Using a bit of cream or coconut milk makes it luxuriously creamy without overpowering the fresh tomato taste.
• Garlic & Onion: These build the flavor base, and sautéing them lightly before adding to the crockpot brings out a deeper, sweeter flavor.
• Olive oil: I like using a good-quality extra virgin olive oil—it adds subtle richness and ties the flavors together beautifully.

Kitchen Equipment Needed

• Crockpot/Slow Cooker: The star of the show—slowly cooks everything to perfection. I love my 6-quart Crock-Pot for soups.
• Cutting Board & Sharp Knife: For chopping fresh tomatoes, onions, and garlic quickly and safely.
• Wooden Spoon or Silicone Spatula: For stirring the ingredients without scratching your crockpot.
• Blender or Immersion Blender: To puree the soup into a smooth, creamy tomato basil soup. I prefer an immersion blender—it’s quick and mess-free.
• Measuring Cups & Spoons: To keep your flavors balanced and consistent every time.

Instructions

1. Prep the Fresh Ingredients

• Wash and chop the fresh tomatoes into medium-sized chunks.
• Dice the onion and mince the garlic.
• Wash and roughly chop the fresh basil leaves.

Pro Tip: Using ripe, juicy tomatoes gives this tomato basil soup with fresh tomatoes a naturally sweet flavor. Overripe tomatoes? Perfect—they’ll make the soup extra rich.

2. Sauté Aromatics (Optional but Recommended)

• In a skillet, heat 2 tbsp olive oil over medium heat.
• Add the diced onions and cook until translucent, about 3–4 minutes.
• Add the garlic and sauté for 30–60 seconds until fragrant.

Pro Tip: Don’t rush this step. Lightly caramelizing the onions adds depth to your crock pot tomato soup with fresh tomatoes.

3. Add Ingredients to the Crockpot

• Transfer the sautéed onions and garlic to the crockpot.
• Add chopped tomatoes, broth, salt, pepper, and sugar (if using).
• Stir gently to combine.

4. Cook the Soup

• Cover and set your crockpot on low for 6–7 hours or high for 3–4 hours.
• Stir once or twice if you’re around—it helps flavors meld but isn’t necessary.

Pro Tip: Low and slow cooking brings out the best flavor, making this easy tomato basil soup rich and comforting.

5. Blend Until Smooth

• Once cooked, remove the soup from heat.
• Use an immersion blender to puree until creamy and smooth, or carefully transfer in batches to a countertop blender.
• Add the fresh basil and blend again briefly to combine.

Pro Tip: If you prefer a chunkier soup, pulse just a few times instead of fully blending.

6. Add Cream and Adjust Seasoning

• Stir in the heavy cream or coconut milk for a creamy tomato basil soup finish.
• Taste and adjust salt or pepper as needed.

7. Serve and Garnish

• Ladle into bowls and top with fresh basil, croutons, or a sprinkle of Parmesan if desired.
• Serve warm and enjoy!

Tips and Tricks for Success

• Use Ripe Tomatoes: Fresh, in-season tomatoes make all the difference in flavor. Overripe ones work beautifully too.
• Low and Slow: Cooking on low heat allows flavors to develop fully and gives a naturally creamy texture.
• Sauté Aromatics: Lightly cooking onions and garlic before adding them boosts the depth of your soup.
• Blend Carefully: Use an immersion blender for convenience and to control texture; pulse in short bursts if you prefer a chunkier soup.
• Taste and Adjust: Always taste before serving—sometimes a pinch of sugar or extra salt can make this healthy tomato basil soup perfect.

Ingredient Substitutions and Variations

• Tomatoes: Swap fresh tomatoes with canned whole peeled tomatoes if out of season—drain and roughly chop first.
• Cream Options: Use coconut milk or Greek yogurt for a dairy-free creamy tomato basil soup.
• Herbs: Add a pinch of thyme or oregano for a slightly different flavor profile.
• Broth: Vegetable broth keeps it vegetarian, chicken broth adds richness.
• Spice it Up: Add red pepper flakes or a dash of smoked paprika for a subtle kick.

Serving Suggestions

• I love serving this creamy tomato basil soup with a classic grilled cheese sandwich—it’s a match made in comfort food heaven!
• Pair it with warm, crusty bread for dipping; the fresh tomato flavors soak into the bread beautifully.
• Drizzle a little extra virgin olive oil and sprinkle Parmesan on top for a simple, elegant touch.
• Serve alongside a fresh green salad with a light vinaigrette to balance the richness of the soup.
• For a cozy weeknight dinner, add a side of roasted vegetables or a soft dinner roll—the whole meal comes together effortlessly.

Frequently Asked Questions

Can I make this soup without a crockpot?

Absolutely! You can simmer all the ingredients on the stove over low heat for 45–60 minutes. Just make sure to stir occasionally and blend at the end for a smooth texture.

Can I use canned tomatoes instead of fresh?

Yes! Use a 28-ounce can of whole peeled tomatoes, roughly chopped. It won’t be quite the same as tomato basil soup with fresh tomatoes, but it’s still delicious.

How can I make this soup dairy-free?

Swap the heavy cream for coconut milk or a non-dairy cream alternative. It keeps the soup creamy without changing the flavor too much.

Can I make this soup ahead of time?

Definitely! The flavors actually deepen if you make it a day ahead. Store in the fridge and reheat gently before serving.

How do I adjust the thickness of the soup?

For a thinner soup, add more broth or water while reheating. For a thicker, creamier texture, blend a little longer or add extra cream.

Can I freeze this soup?

Yes! Let it cool completely, then transfer to a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
