Roasted Garlic Tomato Basil

I came home one rainy October evening craving something warm that didn't require much energy. I had a pile of tomatoes softening on the counter and a whole garlic bulb I kept forgetting to use. Tossing them in the oven felt easier than chopping, and what came out smelled so sweet and deep I almost forgot to blend it.

The first time I made this for my sister, she asked if I'd added butter or sugar because it tasted so rounded and comforting. I hadn't, just roasted everything until the edges darkened and the garlic turned jammy. She went quiet after the second bowl, which is how I knew it worked.

Ingredients

• Ripe tomatoes: Use the softest ones you have, they roast down into pure sweetness and their juices concentrate beautifully in the heat.
• Garlic head: Roasting a whole head transforms sharp garlic into creamy, mellow gold that melts right into the soup base.
• Yellow onion: Quartered and roasted, it caramelizes at the edges and adds a gentle backbone without any bite.
• Carrot and celery: These two bring a quiet earthiness that balances the tomato acidity and makes the broth taste fuller.
• Olive oil: A good drizzle helps everything roast evenly and adds a silky richness that carries through the final blend.
• Vegetable broth: This loosens everything into soup, I like low sodium so I can control the seasoning as it simmers.
• Fresh basil: Stir it in at the end so it stays bright green and aromatic, dried basil just doesn't give the same lift.
• Heavy cream or coconut cream: Optional, but a swirl makes it feel like a hug in a bowl, especially on cold nights.

Instructions

Prep the garlic:

Slice the top off the garlic head to expose the cloves, drizzle with olive oil, and wrap it snugly in foil. This keeps it from drying out and lets it steam into buttery softness.

Roast the vegetables:

Arrange tomatoes cut side up with onion, carrot, and celery on a baking sheet, drizzle with oil, season with salt and pepper, and nestle the foil wrapped garlic alongside. Roast at 400°F for 35 to 40 minutes until the tomatoes are slumped and golden at the edges.

Release the garlic:

Unwrap the foil and squeeze the roasted cloves out of their skins, they should slide right out like soft paste.

Simmer the base:

Transfer all the roasted vegetables and garlic to a large pot, add broth, oregano, and a pinch of sugar if your tomatoes are tart. Bring to a simmer and let it bubble gently for 10 minutes so the flavors marry.

Blend until silky:

Add the fresh basil and blend with an immersion blender until completely smooth, or work in batches in a standard blender. Taste and adjust salt and pepper, then stir in cream if you want extra richness.

One winter night I ladled this into mismatched bowls and set them on the table with torn bread and olive oil. My friend looked up after the first spoonful and said it tasted like someone's Italian grandmother made it, which felt like the best compliment I'd ever gotten for something so simple.

How to Store and Reheat

This soup keeps in the fridge for up to five days and actually tastes better the next day once the basil has steeped into every corner. I freeze it in quart containers without the cream, then stir that in after reheating so it stays silky. Reheat gently on the stove, adding a splash of broth if it thickened up overnight.

What to Serve It With

I almost always make grilled cheese on sourdough to dip into this, the crispy butter and melted cheese against the smooth soup is unbeatable. It's also lovely with a simple green salad dressed in lemon and olive oil, or just crusty bread torn into chunks. On nights when I want something lighter, I top it with croutons and shaved Parmesan instead of cream.

Ways to Make It Your Own

If you like heat, toss in red pepper flakes before blending or drizzle chili oil on top when serving. Smoked paprika stirred in with the oregano gives it a campfire edge that's wonderful in fall. You can also roast a red bell pepper alongside the tomatoes for extra sweetness and body.

• Swap coconut cream for heavy cream to keep it vegan and add a subtle tropical undertone.
• Stir in a handful of spinach or kale right before blending for hidden greens.
• Top with crispy chickpeas or toasted pine nuts for crunch and protein.

This soup has become my answer to gray days and empty fridges, the kind of thing I make without thinking because I know it will feel like enough. I hope it does the same for you.
