Crockpot Tomato Basil Soup

Using fresh tomatoes takes this soup to another level. There’s a bright, tangy sweetness that canned tomatoes can’t quite replicate, and paired with fragrant basil, it creates a harmony of flavors that’s hard to resist.

Equipment

  • Crockpot (Slow Cooker)
  • Cutting board & sharp knife
  • Wooden Spoon or Silicone Spatula
  • Blender or immersion blender
  • Measuring Cups & Spoons

Ingredients
  

For the Soup

  • 2 lbs fresh tomatoes chopped
  • 1 medium onion diced
  • 3 cloves garlic minced
  • 4 cups vegetable or chicken broth
  • 1 cup fresh basil leaves packed
  • 1 tsp salt adjust to taste
  • ½ tsp black pepper
  • 1 tsp sugar optional, to balance acidity
  • ½ cup heavy cream or coconut milk for creamy tomato basil soup
  • 2 tbsp olive oil

Optional Garnishes

  • Fresh basil leaves chopped

  • Grated Parmesan cheese

Instructions
 

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.

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.

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.

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.

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.

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.

Serve and Garnish

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