Save There's something about the smell of roasting garlic that stops me mid-task, no matter what I'm doing. One lazy Sunday afternoon, I had about an hour and wanted something warm that felt like a hug, so I threw tomatoes and a whole bulb of garlic into the oven and walked away. The house filled with this golden, almost caramel-like aroma, and by the time I blended everything together with cream, I realized I'd stumbled onto something that tastes like it took hours but really didn't.
I made this for my sister on a rainy Tuesday when she needed comfort food and wasn't in the mood to talk much. She took one spoonful, closed her eyes, and didn't say anything for a minute, which told me everything. Now whenever she's had a rough day, she texts me asking if I'm making the roasted garlic soup.
Ingredients
- Ripe tomatoes, 1.5 lbs halved: Look for tomatoes that feel heavy for their size and smell sweet at the base; they'll caramelize beautifully and give you real tomato flavor, not just acidity.
- Yellow onion, 1 large cut into wedges: The wedges will soften and almost dissolve into the soup, adding sweetness that balances everything.
- Garlic bulb, 1 whole: Roasting transforms garlic from sharp to mellow and butter-soft, so don't skip this or use minced garlic as a shortcut.
- Olive oil, 2 tbsp: Use good oil because it's one of the few flavors that isn't masked by roasting.
- Heavy cream, 1/2 cup: This is what turns it from nice soup into the kind you want to keep eating.
- Vegetable broth, 2 cups: Low-sodium broth lets the roasted flavors shine without background noise.
- Salt, 1 tsp plus more to taste: Taste as you go; roasting concentrates flavors, so you might need less salt than you'd expect.
- Black pepper, 1/2 tsp freshly ground: Freshly ground matters here because you'll actually taste the pepper against the cream.
- Sugar, 1/2 tsp optional: A pinch fixes that sharp tomato tang if your batch leans acidic.
- Smoked paprika, 1/4 tsp optional: This adds a whisper of depth without announcing itself.
- Fresh basil and croutons for garnish: Basil wakes everything up, and croutons give you texture when you want it.
Instructions
- Heat your oven and prep everything:
- Preheat to 400°F. Halve your tomatoes and cut the onion into wedges, then slice the top off your garlic bulb to expose the cloves. You'll see the papery skin fall away a little, which means the roasting will work its magic.
- Oil and season before roasting:
- Arrange tomatoes cut-side up and onion wedges on a baking sheet. Drizzle the garlic bulb with a small amount of olive oil and wrap it loosely in foil so steam can escape. Coat the tomatoes and onions with the rest of the oil, then scatter salt and pepper over everything.
- Roast until caramelized:
- Pop everything in for 35 to 40 minutes. You're looking for the tomato edges to turn brown and the flesh to collapse slightly, and the garlic will smell nutty and sweet when it's done. Your kitchen will smell incredible.
- Squeeze and blend:
- Once cool enough to touch, squeeze the roasted garlic cloves out of their skins into your blender. Add the roasted tomatoes, onions, and vegetable broth, then blend until completely smooth, working in batches if you need to.
- Finish with cream and flavor:
- Pour the blended soup into a large pot over medium-low heat. Stir in the heavy cream and paprika if you're using it, then taste. Add a tiny pinch of sugar if the soup tastes sharp rather than balanced.
- Simmer and adjust:
- Let it bubble gently for about 10 minutes, stirring now and then. Taste again and add more salt or pepper if it needs it, then serve it hot with whatever garnish calls to you.
Save I learned the hard way that this soup tastes even better the next day after the flavors have settled into each other overnight. Now I always make a double batch, knowing the second bowl will be worth waiting for.
Making It Your Own
This recipe is flexible in the way that matters. If you have an immersion blender, you don't need to transfer to a blender at all, which saves dishes and keeps the mess contained. Some days I add a splash of balsamic vinegar for depth, and other times I stir in a pinch of chili flakes because I want heat. The base is so solid that you can lean into whatever your kitchen is already set up for.
Pairing and Serving
This soup asks for something on the side. A grilled cheese sandwich is the obvious answer, but I've also served it with crusty bread for soaking, or paired it with a light salad when I wanted something less heavy. The cream is rich enough that the soup doesn't need much company, just something to anchor the meal.
Storage and Reheating
The soup keeps in the refrigerator for about four days in an airtight container, and honestly gets better as it sits. When you reheat it, go slow over medium-low heat and stir often so the cream doesn't separate. You can also freeze it in portions for up to three months, though let it thaw in the fridge first and taste for seasoning when you warm it up.
- Add fresh basil only right before serving so it stays bright and doesn't turn dark.
- If the soup thickens too much when chilled, thin it with a splash of broth or cream when reheating.
- Croutons go in at the last second so they stay crispy instead of turning soggy.
Save This soup became my answer to almost everything: a quiet lunch, a last-minute dinner, or something to bring to someone who needed feeding. It's proof that the simplest recipes, made with care, are often the ones people remember.
