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.

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
- Croutons
- Grated Parmesan cheese
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.
