What is Roasted Tomato Soup?
Roasted Tomato Soup is a rich, velvety soup made from fresh tomatoes that are oven-roasted with onions, garlic, olive oil, and a few simple seasonings. The roasting process concentrates the natural sweetness of the tomatoes and brings out their bold, slightly smoky flavor. After roasting, everything is blended together with broth and fresh basil to create a smooth, deeply flavored soup that’s both simple and satisfying. Unlike canned versions, homemade Roasted Tomato Soup has that rustic, garden-fresh taste — the kind that makes you question why you ever settled for store-bought. It’s also completely customizable: keep it light and herby, or swirl in a touch of cream for extra indulgence.
Reasons to Try Roasted Tomato Soup
If you’ve never made Roasted Tomato Soup from scratch, let me give you three delicious reasons to change that. First, it’s ridiculously easy — just roast, blend, and serve. No fancy equipment or complicated steps here. Second, it’s healthy comfort food at its best. Packed with antioxidants, vitamin C, and fiber from the tomatoes, it’s a feel-good meal that doesn’t taste like a compromise. Third, it’s the perfect make-ahead dish. You can double the batch, freeze half, and have homemade soup ready for any busy weeknight. Plus, the aroma while it’s roasting? Let’s just say it’ll make your kitchen smell like a five-star café.
Ingredients Needed to Make Roasted Tomato Soup
- 1 ½ pounds Roma, beefsteak, or heirloom tomatoes, quartered (about 4 heaping cups)
- 1 yellow onion, chopped
- 1 head of garlic, sliced in half
- 2 tablespoons olive oil
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- 2 cups vegetable or chicken broth
- ¼ cup fresh basil
Instructions: Step-by-Step Guide to Making Roasted Tomato Soup
Making this Roasted Tomato Soup is easier than you might think, and with this step-by-step guide, you’ll have a pot of rich, comforting soup ready in under an hour. Follow along as we go from prepping those juicy tomatoes to serving a silky-smooth bowl of flavor perfection.
Step 1: Preheat and Prep
Start by preheating your oven to 450°F (232°C) — this high heat helps caramelize the tomatoes, unlocking that signature roasted sweetness. While the oven heats up, gather your ingredients: ripe Roma or heirloom tomatoes, a yellow onion, a head of garlic, olive oil, salt, and pepper.
Slice the tomatoes into quarters and roughly chop the onion. For the garlic, don’t peel the cloves — instead, slice the entire head in half horizontally. This will make it easier to squeeze out the roasted cloves later. If you’re new to prepping fresh produce efficiently, check out our vegetable prep tips to save time and keep your chopping consistent.
Step 2: Season and Arrange
Next, place the tomatoes, onion, and halved garlic head into a large oven-safe Dutch oven or roasting dish. Drizzle everything generously with olive oil — about two tablespoons — and sprinkle with kosher salt and black pepper. Toss the vegetables gently so every piece is evenly coated.
This is where the magic starts: roasting vegetables brings out their natural sugars and adds depth to your soup’s flavor. For a touch of extra sweetness, you can even toss in a few cherry tomatoes. (Need to substitute ingredients? Visit our ingredient swaps guide for practical kitchen alternatives.)
Step 3: Roast Until Beautifully Blistered
Place your pot uncovered in the preheated oven and roast for 40–45 minutes. During this time, your kitchen will smell heavenly — a mix of caramelized onions and slow-roasted garlic. The tomatoes should soften and start to wrinkle, with a few charred edges here and there.
If you notice your garlic browning too quickly, lightly cover the top with foil for the remainder of the cooking time. This step is key to developing that rich, complex base you can’t get from canned soup.
Step 4: Add Broth and Basil
Carefully remove the pot from the oven (it’ll be hot!). Let it cool slightly, then use tongs or your fingers to squeeze the roasted garlic cloves out of their peels. They should slide out easily, buttery and golden.
Pour in 2 cups of vegetable or chicken broth, depending on your flavor preference, and toss in a handful of fresh basil leaves. The basil adds a bright, herby note that balances the deep roasted flavors. Stir gently to combine — it’s already looking like something you’d find in a cozy café.
Step 5: Blend Until Silky Smooth
Now it’s time to blend. Using an immersion blender, blend the soup right in the pot until it reaches a smooth, velvety texture. If you prefer a chunkier finish, pulse a few times instead of blending fully.
No immersion blender? No problem. Carefully transfer the mixture to a countertop blender in batches, leaving the lid slightly ajar to let steam escape. Remember, hot liquids expand when blended — check out our tips for blending hot soups safely to keep things mess-free.
Step 6: Taste and Adjust
Once blended, taste your soup and season it to your liking. You might want to add another pinch of salt, a grind of pepper, or even a dash of red pepper flakes for some gentle heat. If the soup tastes too acidic, stir in a teaspoon of honey or cream to mellow it out.
This is also a good time to play with toppings — a sprinkle of parmesan cheese, a drizzle of olive oil, or a spoonful of pesto can all take this soup from simple to spectacular.
Step 7: Serve and Savor
Ladle your freshly blended Roasted Tomato Soup into warm bowls and garnish with extra basil leaves. For the perfect pairing, serve it alongside a gooey grilled cheese sandwich or a slice of buttery garlic bread. If you’re in the mood for a full cozy meal, it also pairs beautifully with our Chicken Orzo Tomato Soup Recipe or a crisp green salad.
What to Serve with Roasted Tomato Soup
There’s a reason Roasted Tomato Soup and grilled cheese are a love story for the ages — the buttery crunch of the sandwich pairs perfectly with the soup’s creamy tang. But if you want to mix things up, try serving it with a slice of crusty sourdough, a side of roasted vegetables, or a fresh green salad. It also makes a comforting starter for hearty mains like this Hearty Green Chile Stew or Crockpot Chicken and Dumplings. For something a little indulgent, add a drizzle of cream or top with a few homemade croutons for extra texture.
Key Tips for Making Roasted Tomato Soup
Start with ripe tomatoes — they’ll give your soup the best sweetness and depth of flavor. Don’t skip the roasted garlic step; it’s what makes this soup unforgettable. When blending, be cautious with hot liquids (an immersion blender is safest). Season at the end and don’t be afraid to play — add red pepper flakes for heat or a splash of cream for extra richness. And if you really want to impress, finish with a swirl of olive oil and a sprinkle of freshly grated parmesan.
Storage and Reheating Tips for Roasted Tomato Soup
Store leftover soup in an airtight container in the refrigerator for up to 4 days. It also freezes beautifully — pour cooled soup into freezer-safe containers or bags and freeze for up to 3 months. To reheat, thaw overnight in the fridge, then warm gently on the stove over medium heat until hot. You can also microwave it in a safe bowl for about 2 minutes, stirring halfway through. Pro tip: make a double batch, freeze half, and thank yourself on your next busy day.
FAQs
Can I use canned tomatoes? Yes, though fresh roasted ones add a deeper flavor. Use good-quality whole canned tomatoes and roast them briefly for similar results.
Can I make it dairy-free? Absolutely. This recipe is naturally dairy-free, but you can add coconut milk for creaminess if desired.
Can I use dried basil instead of fresh? You can, but reduce it to about 1 teaspoon since dried herbs are more concentrated.

Roasted Tomato Soup is the kind of recipe that reminds you why simple ingredients are often the best. It’s cozy, nourishing, and endlessly adaptable — perfect for chilly nights or lazy Sundays. Whether you’re serving it with a golden grilled cheese or enjoying it solo, this soup delivers comfort in every spoonful.
