So, you’re craving something cozy, creamy, and delicious but don’t feel like doing anything that resembles “actual work”? Enter slow cooker tomato basil soup—aka the dish that makes you look like a culinary genius when in reality, your biggest effort was plugging in an appliance. Lazy cooking at its finest.
Why This Recipe is Awesome
This soup is basically comfort food in a bowl with a side of “I didn’t even try.” It’s idiot-proof, and I say that with love. Toss a bunch of tomatoes, onions, garlic, and broth into your slow cooker, forget about it for hours, and boom—you’ve got something that tastes like it came from a fancy café.
Also, can we talk versatility? You can serve it plain, swirl in cream, or dunk in grilled cheese (which, let’s be honest, is the real reason most of us make tomato soup in the first place). Plus, this soup has that magical combo of being both healthy and indulgent depending on how much cream and cheese you sneak in.
Ingredients You’ll Need
- 2 cans (28 oz each) crushed tomatoes (tomato heroes in a can)
- 1 medium onion, chopped (yes, tears may happen)
- 3 garlic cloves, minced (because flavor without garlic is a crime)
- 2 cups vegetable broth (or chicken broth if that’s your vibe)
- 1 teaspoon dried basil (or fresh if you’re feeling fancy)
- 1 teaspoon dried oregano (because basil needs a buddy)
- 1 tablespoon sugar (helps tame tomato tang)
- 1 teaspoon salt (adjust later if you’re picky)
- ½ teaspoon black pepper (add more if you like a kick)
- 1 cup heavy cream or half-and-half (optional, but highly recommended for maximum coziness)
- ½ cup grated Parmesan cheese (because cheese makes everything magical)
- Fresh basil leaves for garnish (so you can pretend you’re a food stylist)
Step-by-Step Instructions
- Throw the tomatoes, onion, garlic, broth, basil, oregano, sugar, salt, and pepper into your slow cooker. Give it a stir like you know what you’re doing.
- Cook on low for 6–8 hours or high for 3–4 hours. Translation: live your life while the soup babysits itself.
- Once it’s all soft and aromatic, blend it with an immersion blender right in the slow cooker. No immersion blender? Carefully transfer batches to a regular blender. Try not to redecorate your kitchen with soup splatters.
- Stir in cream and Parmesan cheese until silky and smooth. Taste, adjust seasoning, and try not to “accidentally” eat half the pot before serving.
- Ladle into bowls, garnish with fresh basil, and dunk grilled cheese like the pro you are.
Common Mistakes to Avoid
- Forgetting the sugar. Tomatoes are tangy little divas—sugar balances them out.
- Adding cream too early. Unless you enjoy curdled soup, wait until the end.
- Over-blending. You want silky soup, not tomato smoothie.
- Skipping Parmesan. I mean, you could… but why would you punish yourself like that?
- Not making grilled cheese. The soup is fabulous alone, but grilled cheese makes it legendary.
Alternatives & Substitutions
- No cream? Use milk, coconut milk, or skip it entirely for a lighter vibe.
- No Parmesan? Try Romano or Asiago. Or, if you’re dairy-free, nutritional yeast adds a cheesy vibe.
- Fresh tomatoes instead of canned? Go for it, but roast them first for maximum flavor payoff.
- Want it spicy? Add a pinch of red pepper flakes. Tomato basil soup with a kick? Yes, please.
- Need it vegan? Use veggie broth, skip the cream, and swap cheese for plant-based alternatives. Easy win.
FAQ (Frequently Asked Questions)
Can I freeze this soup?
Totally. Just skip adding the cream before freezing. Add it after reheating.
Do I have to blend it?
Not if you like chunky soup, but blending = silky perfection. Highly recommended.
Can I use fresh basil instead of dried?
Yes! Add it at the end so it doesn’t turn brown and sad.
Will almond milk work instead of cream?
Technically, yes. Will it be as dreamy? Probably not, but you do you.
How long will it last in the fridge?
About 4–5 days. It’s even better the next day once the flavors mingle.
What’s the best bread for dipping?
Sourdough or ciabatta. Basically, anything sturdy enough to hold maximum soup without collapsing.

Nah. That’s the beauty of a slow cooker—it takes care of softening them for you.
