Roasted Garlic Tomato Basil

One Sunday in late September, I opened my oven to pull out a tray of tomatoes and garlic that had been roasting for nearly forty minutes, and the smell that hit me was so sweet and deep I actually stood there for a moment just breathing it in. I had bought too many tomatoes at the farmers market again, and instead of letting them go soft on the counter, I decided to roast them with a whole head of garlic and see what happened. What happened was this soup, and Ive made it at least once a month ever since.

I made this for my neighbor after she had surgery, and when I dropped it off she told me later that it was the first thing that actually tasted good to her in days. She said the basil made it feel bright even though it was rich, and that the garlic didnt sit heavy the way she thought it might. I brought her another batch the following week, this time with a loaf of sourdough, and she texted me a photo of her empty bowl with just a heart emoji.

Ingredients

• Ripe tomatoes: Use the ripest ones you can find, they get sweeter and more concentrated in the oven, and any variety works as long as theyre soft to the touch.
• Garlic head: Roasting a whole head might sound like a lot, but it becomes buttery and mild, and you just squeeze the cloves right out of their skins.
• Yellow onion: I quarter it so it roasts evenly, and it adds a subtle sweetness that balances the acidity of the tomatoes.
• Carrot and celery: These give the soup a deeper vegetable base and a little earthiness without taking over the flavor.
• Olive oil: I use it to coat everything before roasting, and it helps the vegetables caramelize instead of just steaming.
• Vegetable broth: Homemade is lovely, but a good quality store-bought works perfectly, just check the sodium level so you can control the salt.
• Fresh basil: Add it at the end so it stays bright green and fragrant, dried basil wont give you that same freshness.
• Heavy cream or coconut cream: This is optional, but a splash makes the soup velvety and rounds out the acidity, coconut cream works beautifully if youre avoiding dairy.

Instructions

Prep the garlic:

Slice off the top of the garlic head so the cloves are just barely exposed, drizzle it with olive oil, and wrap it snugly in foil. This keeps it from drying out and lets it get soft and golden.

Arrange the vegetables:

Lay your tomato halves cut side up on a baking sheet with the onion, carrot, and celery, drizzle everything with olive oil, and season well with salt and pepper. Tuck the foil-wrapped garlic on the sheet too.

Roast until caramelized:

Let everything roast at 400°F for 35 to 40 minutes, until the tomatoes have collapsed and their edges are a little browned, and the garlic feels soft when you press the foil. The kitchen will smell incredible.

Squeeze the garlic:

Unwrap the garlic carefully, it will be hot, and squeeze each clove out of its skin into your pot. Theyll slide right out like little nuggets of butter.

Simmer the base:

Add all the roasted vegetables, the broth, oregano, and a teaspoon of sugar if your tomatoes are tart, then bring it to a gentle simmer and let it cook for 10 minutes. This lets the flavors settle into each other.

Blend with basil:

Toss in your fresh basil leaves and blend everything with an immersion blender until its completely smooth and silky. If youre using a regular blender, do it in batches and leave the lid slightly vented so steam can escape.

Finish and season:

Stir in your cream if youre using it, taste, and adjust the salt and pepper. Serve it hot with a drizzle of olive oil or a few torn basil leaves on top.

The first time I served this at a dinner party, my friend Sarah, who normally doesnt like cooked tomatoes, had two bowls and asked if I could write down the recipe for her. She said it tasted nothing like the canned tomato soup she remembered from childhood, and I realized thats because the roasting changes everything about the flavor. It became the soup I make when I want to impress someone without actually stressing myself out.

How to Store and Reheat

This soup keeps beautifully in the fridge for up to five days in an airtight container, and it actually tastes even better the next day once the flavors have had time to settle. I reheat it gently on the stovetop over low heat, stirring occasionally, and if it seems too thick I add a splash of broth or water to loosen it up. You can also freeze it for up to three months, just leave out the cream and stir that in fresh when you reheat it so the texture stays smooth.

What to Serve It With

I almost always serve this with crusty bread, the kind with a chewy crust that you can drag through the bowl to get every last bit of soup. A grilled cheese sandwich on sourdough is the ultimate pairing, especially if you use a sharp cheddar or gruyere that melts into all the nooks. If Im keeping it lighter, I sometimes add a simple arugula salad on the side with lemon and olive oil, the peppery greens cut through the richness in a way that feels just right.

Ways to Make It Your Own

If you like a little heat, add a pinch of red pepper flakes to the pot before you blend, it gives the soup a subtle warmth that doesnt overpower the sweetness of the tomatoes. Ive also made this with fire-roasted canned tomatoes in the winter when fresh ones arent great, and while its not quite the same, it still works if you add an extra drizzle of olive oil and maybe a touch more sugar. You can stir in white beans or chickpeas after blending for extra protein, or top each bowl with crispy croutons or a handful of grated parmesan.

• Try adding a splash of balsamic vinegar at the end for a deeper, slightly tangy finish.
• Swap the basil for fresh thyme or rosemary if thats what you have, the flavor will be more earthy but still delicious.
• For a thicker, heartier soup, roast a red bell pepper along with the tomatoes and blend it in.

This soup has become my answer to grey afternoons and the kind of hunger that wants something warm and gentle. I hope it finds a spot in your kitchen the way it has in mine.
