Save There's something about the smell of tomatoes hitting hot oil that makes even the smallest kitchen feel like a proper restaurant. My neighbor stopped by one afternoon while I was making this soup, and the aroma pulled her right into the kitchen before she could even say hello. She stood there watching the tomatoes break down, asking questions about every step, and by the time I handed her a bowl with that drizzle of green oil on top, she'd already decided this would be her go-to recipe. That's when I knew I'd found something special—a soup so straightforward it almost feels like cheating, yet it tastes like you've been stirring it all day.
I made this for my sister during her first week in a new apartment when she had nothing but a hot plate and determination. The kitchen was bare except for these ingredients and a borrowed immersion blender, yet somehow the whole place filled with warmth. She texted me a photo of her bowl with the words 'this is better than my old roommate's fancy soups,' and I've never let her forget it. That moment made me realize this recipe is proof that you don't need much to make something memorable—just good ingredients and a little patience.
Ingredients
- Ripe tomatoes, 1.5 kg roughly chopped: Use tomatoes at peak ripeness, ideally from late summer or a farmers market—the difference is immediate and undeniable.
- Yellow onion, 1 medium diced: The base of everything; don't skip this or rush it, as slow softening builds the foundation.
- Garlic, 2 cloves minced: Just enough to whisper through the soup without shouting—more if you're a true garlic devotee.
- Vegetable broth, 750 ml: Use good quality or homemade if you have it; it's the invisible backbone holding everything together.
- Extra virgin olive oil, 2 tbsp plus more for drizzling: This isn't the place to economize—real olive oil makes the final drizzle taste like liquid gold.
- Fresh basil leaves, 1 small bunch plus extra for garnish: Add it at the end so the flavor stays bright and alive instead of cooking away into memory.
- Sugar, 1 tsp optional: Only if your tomatoes are tart; a pinch balances acidity without making it taste sweet.
- Salt and freshly ground black pepper to taste: Season gradually and taste as you go—this is where your own touch matters.
- Heavy cream or plant-based cream, 60 ml optional: A swirl adds luxury, but the soup sings on its own without it too.
Instructions
- Warm your foundation:
- Heat olive oil in a large pot over medium heat and add the diced onion, letting it soften and turn translucent for about 5 minutes—you'll know it's ready when it smells sweet and looks almost glassy.
- Wake up the garlic:
- Stir in the minced garlic and cook for just 1 minute until the kitchen fills with that unmistakable fragrance, watching carefully so it doesn't brown.
- Welcome the tomatoes:
- Add your roughly chopped tomatoes and let them cook for 10 minutes, stirring occasionally, until they start to surrender and break apart—the juices will begin pooling at the bottom.
- Build the broth and simmer:
- Pour in the vegetable broth and bring everything to a gentle simmer, adding a small pinch of sugar if your tomatoes lean tart. Let it bubble softly uncovered for 15 minutes, allowing flavors to marry.
- Blend to silky perfection:
- Remove the pot from heat, add your basil leaves, then use an immersion blender to purée until completely smooth—or work in batches with a countertop blender if you prefer. The texture should feel velvety on your tongue.
- Season and enrich:
- Taste the soup and adjust salt and pepper to your preference, then stir in cream if you're using it, watching as it swirls into pretty clouds.
- Serve with ceremony:
- Ladle the soup into bowls and finish each one with a generous drizzle of good olive oil and a few fresh basil leaves so people know exactly what they're tasting.
Save My mother-in-law tasted this soup and declared it the reason she finally understood why I choose cooking over going out most nights. She asked for the recipe three times that evening, each time convinced she'd misheard something so simple, convinced there must be a secret. When I assured her there wasn't, she smiled and said 'sometimes the secret is that there is no secret—just caring enough to pay attention.'
Why Temperature and Timing Matter
Medium heat isn't arbitrary—it gives the onion time to sweeten rather than brown, and it lets the tomatoes release their juices gently instead of splattering everywhere. I learned this the hard way by rushing and cranking the heat, only to end up with charred onions and a bitter undertone that no amount of basil could fix. The 15-minute simmer is where the magic happens; it's not long enough to stew away the tomato's brightness, but long enough for everything to become one unified voice instead of separate ingredients shouting over each other.
The Olive Oil Finish Makes All the Difference
A soup this simple lives or dies by its final drizzle. I used to skip this step, thinking it was fussy, until someone pointed out that the silky soup needs something with personality on top. That green oil adds richness, prevents the surface from looking lonely, and gives you something to taste first—it's the reason people pause and say 'wow' before they've even sipped. Good olive oil costs a bit more, but on a bowl of tomato soup it's not a luxury, it's the whole point.
Variations and Kitchen Adventures
This recipe is a starting point, not a boundary. I've made it with roasted tomatoes (which deepens the flavor to almost caramel-like intensity), with a splash of balsamic vinegar, with a handful of spinach stirred in at the end, and once with a whole dried chili pepper floating around for gentle heat. Each version felt like a small discovery rather than an accident. The soup responds well to your mood and your pantry, which is exactly what you want from something this straightforward.
- Roast your tomatoes first at 200°C for 30 minutes if you want a deeper, richer flavor and don't mind the extra time.
- A grilled cheese sandwich dipped into this soup is a combination that should be taught in schools.
- Leftovers keep beautifully for four days, and the flavor actually improves as it sits.
Save This soup has become the thing I reach for when I want to prove that real cooking doesn't require complexity or hours at the stove. It's proof that sometimes the best recipes are the ones that get out of the way and let good ingredients shine.
Questions & Answers

Crusty bread, grilled cheese sandwiches, garlic bread, or a simple green salad make excellent accompaniments.
- → How do I make it smoother?
