Creamy Roasted Tomato Soup (2024)

With or without grilled cheese, this beloved classic blows the lid off its canned counterparts. Creamy Roasted Tomato Soup features slow-roasted ripe tomatoes and garlic with a peppery kick of garden-fresh basil. Pureed to perfection with just a dash of cream, this fresh tomato soup is naturally vegetarian, with vegan, paleo, and Whole30 options.

Here at OSK, we subtly espouse our values in many ways, predominantly by just doing our thing and creatingeasy, seasonal recipesfrom real,whole foodsthat aresimply prepared.

And also we occasionally talk smack. One of our most precious core values is “no food shaming.” We recognize everyone has different needs, schedules, resources, and access – us included.

I have absolutely consumed and served (not to the Queen, or anything…) canned soup before and I will absolutely do it again. But it is very important to me that you know that canned tomato soup is sh*t. Not the sh*t. sh*t. And believe me when I tell you that I completely understand its thrall. But it is also important to me that you know that “thrall” is just sugar. (Sweet lord, so much of the hold food has on us is just sugar in disguise.)

Reader, do not mistake my disdain as one for canned goods in general or canned tomatoes specifically. I use canned tomato products (fire-roasted canned tomatoes, tomato paste, etc.) all the time. Very recently, in fact, in a completely different tomato-based soup recipe.

But mama got lazy and dug out a can of organic creamy tomato basil soup to go with the kids’ lunch and it had 20 grams of added sugar in it. (And yes I understand sugar is organic.) Surprisingly, there’s actually less added sugar in a can of the condensed stuff.

I could rant all day (too late!) about why this is, but suffice it to say, tomatoes are already sweet. When you cook them (especially when you roast), they get sweeter – on their own. I’m not saying pre-made tomato soup isn’t tasty (it is); but it’s not as good as tomato soup from scratch made with fresh, roasted tomatoes. And it’s not nearly as good for you. With tomato season around the corner, I implore you, to at least once roast your own tomatoes, make a batch and see for yourself.

Why Roast Fresh Tomatoes?

It is a truth universally acknowledged that roasting pretty much makes every vegetable better and tomatoes are no exception.

Aside from the fact that roasting tomatoes actually makes them healthier (by releasing more of the antioxidant lycopene), I find it’s also the most-efficient means to break down the plant material (which allows for a smoother – and shorter – puree when you’re making tomato soup from fresh tomatoes) that coincidentally, also produces the best flavor. Because that flavor intensifies. Like, way intensifies. Fresh tomatoes are sweet and bright, but when roasted, that sweetness concentrates into tangy deliciousness with notes of caramel.

Roasted fresh tomatoes are, simply put, better all around.

What Kind of Tomatoes Should I Use?

To be honest, the varietal doesn’t matter as much as freshness does. The best tomatoes for fresh tomato soup are locally sourced, perfectly ripe, and super juicy. Garden tomatoes are perfect, but so are heirlooms from your local farmer’s market, or roma’s from your co-op. This soup is perfect for those “ugly” tomatoes your farmer is selling for half-price – they might not be perfectly round, but if they’re ripe and juicy, they’re perfect for this recipe!

How to Make Roasted Tomato Soup

Fresh garden tomatoes shine in thisRoasted Tomato Souprecipe. Tomatoes and garlic are slow-roasted to enhance their naturally sweet flavors, then blended with a simple seasoned base and of course lots of fresh basil. It’s a vegetarian family favorite!

1. Toss fresh tomatoes and whole garlic cloves with olive oil, salt and pepper on parchment lined baking sheet.
2. Roast for 1 hour in a 400°F oven, or until very soft and charred around the edges.
3. Remove the garlic cloves and set aside to cool.
4. Squeeze the roasted garlic from the paper shell.
5. Saute a diced sweet onion in olive oil until soft; add dried basil and oregano and saute 1 minute more.
6. Add balsamic vinegar to deglaze the pot. IMPORTANT! Cook until the vinegar stops bubbling and is reduced by at least half. This will cook down the vinegar, remove the bitter and acidic notes, and create a sweeter soup.
7. Pour in broth and fresh thyme. Simmer the broth for 15-20 minutes, or until infused with flavor. Remove the thyme after simmering.
8. Add the roasted tomatoes, roasted garlic, and fresh basil to the broth. Give everything a good stir.
9. Pour in the heavy cream (if using), then puree using an immersion blender, or in batches in a stand blender.

Tips for Making This Recipe Perfectly

• Use thefreshest, ripest tomatoesyou can find for superior flavor. The varietal doesn’t matter as long as they’re ripe and juicy.
• If using larger tomatoes, cut the quarters in half before roasting.
• Fresh basilis also essential. It’s naturally sweetandpeppery, and perfectly complements the acidity of the tomatoes.
• If you don’t have fresh thyme, add a pinch of dried thyme along with the basil and oregano.
• Don’t rush the roasting process. Roasting the tomatoes and garlic will enhance and reveal their natural sugars, and simply adding sugar doesn’t compare. You want the tomatoes to be very soft, with lightly charred edges. The garlic cloves should be soft, with caramelized papery skins.
• This soup doesn’t simmer long, so it’s important to start with agood quality vegetable stockthat’s infused with flavor. Use homemade if you have it. You could also use homemade chicken stock, which will add another layer of richness.
• Adding cream is optional(but recommended!). A little goes a long way, and I added just a quarter cup. You can add up to a half cup without sacrificing the roasted tomato flavor.

Sensitive to Acid?

Tomatoes are very acidic. While roasting them helps tame the some of the acidic flavor, if you’re still sensitive to acid, here’s a trick: add baking soda! Just ½ teaspoon of baking soda will neutralize the acid in the tomatoes, allowing their rich flavor to really shine. Sprinkle the baking soda over the roasted tomatoes when you add them to the soup pot.

Make It Your Way

• Vegan: use good quality vegetable broth, and substitute coconut cream or full-fat coconut milk for the heavy cream.
• Paleo and Whole30: use bone broth (good quality store-bought or homemade), and substitute coconut cream or full-fat coconut milk for the heavy cream.
