Soups & Stews
The 110 grill tomato soup delivers smoky, charred flavor without needing an outdoor fire—just a stovetop grill pan. This technique transforms simple tomatoes into a rich, velvety soup with deep, caramelized notes that taste like summer in a bowl.

Ingredients for 110 grill tomato soup
Pantry staples plus a few fresh ingredients transform into smoky, velvety tomato soup magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Roma Tomatoes 🍅 | 2 lbs | Halved, seeds removed |
| Yellow Onion 🧅 | 1 whole | Chopped into 1/2-inch pieces |
| Garlic Cloves 🧄 | 4 cloves | Peeled and smashed |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For charring tomatoes |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred |
| Fresh Basil Leaves 🌿 | ½ cup | Packed, stems removed |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Or 1 tsp dried thyme |
| Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Balsamic Vinegar 🍷 | 1 tbsp | For brightness |
| Heavy Cream 🥛 | ½ cup | Optional for richness |
| Crusty Bread 🍞 | 4 slices | For serving (optional) |
The tomatoes are the star—Roma are ideal because they're meaty and hold up to charring. Grab a 2-pound bag from the produce section, or hit the farmers market for even fresher ones. Look for firm, vibrant tomatoes with no soft spots—they'll char beautifully. If you're short on time, heirloom tomatoes from Trader Joe's work great too. The key is to halve them evenly so they cook consistently in the grill pan. I always keep a small bowl of ice water nearby to plunge charred tomatoes into—stops the cooking process instantly and makes peeling the skins way easier.
No Roma tomatoes? Regular vine-ripened tomatoes work in a pinch, but you might need to use more since they're juicier. Fresh basil and thyme can be swapped for dried at one-third the amount if you're out, but fresh gives that bright, herby punch. The balsamic vinegar adds depth—substitute lemon juice if you prefer a tangier finish. For the vegetable broth, low-sodium is a must unless you're okay with extra salt. Want to make this dairy-free? Skip the heavy cream and stir in coconut milk instead for a lighter texture. The grill pan is non-negotiable for that smoky flavor, but if you're really stuck, a cast-iron skillet works too.
This soup tastes even better the next day—4-5 days in the fridge, no problem. For longer storage, freeze for up to 3 months. I always make a double batch because it disappears fast. The crusty bread topping is optional but worth it—toast it in the grill pan with a little olive oil for extra smoky flavor. If you're serving it chilled, let it cool completely first. The cream, if using, will separate when cold—just give it a quick whisk before serving. Leftovers reheat beautifully—just warm gently on the stove or microwave until steaming.

Step-by-step instructions for smoky-grilled tomato soup
This method delivers restaurant-quality smoky flavor without ever touching a grill.
Char the Tomatoes for Deep Flavor
Preheat your oven's broiler to high. Line a baking sheet with aluminum foil and arrange the halved Roma tomatoes cut-side up. Drizzle each half with 2 tablespoons of the extra-virgin olive oil and sprinkle with ½ teaspoon of the kosher salt. Place the baking sheet 4-6 inches from the broiler element and broil for 5-7 minutes until the edges are deeply charred and blistered.
Watch closely—the tomatoes should develop dark, caramelized spots while the flesh remains tender. Rotate the pan halfway through for even charring. The charred skin is where all that smoky flavor comes from, so don't rush this step. Once charred, remove the tomatoes and set aside in a bowl to cool slightly.
Sauté Onion and Garlic for Foundational Flavor
Heat the remaining 0.3 cup extra-virgin olive oil in a large Dutch oven over medium heat. Add the chopped yellow onion and cook for 5-6 minutes until softened and golden, stirring occasionally. Add the smashed garlic cloves and cook for 30 seconds until fragrant—just until you can smell that irresistible aroma.
Be careful not to let the garlic burn, as it can quickly turn bitter. If it starts to darken too quickly, remove the pan from heat for a moment. The onions should be tender but not browned at this stage—you're building flavor, not color. This aromatic base will carry through the entire soup.
Build the Soup Base with Broth and Herbs
Use a spoon to scrape up any browned bits from the bottom of the Dutch oven—these contain concentrated flavor. Add the charred tomatoes (with their juices), vegetable broth, fresh basil leaves, and fresh thyme leaves. Bring to a simmer over medium-high heat, then reduce heat to medium-low and let it cook uncovered for 15-20 minutes until the tomatoes break down and the flavors meld together.
Stir occasionally and taste the soup as it cooks. You'll notice the flavors deepening and becoming more complex. The tomatoes should soften completely, releasing their juices and creating a velvety texture. This is where the magic happens—the charred tomatoes infuse the broth with their smoky essence.
Finish with Brightness and Creaminess
Strain the soup through a fine-mesh sieve into a clean pot, pressing gently on the solids to extract maximum flavor. Return the soup to medium heat and stir in the balsamic vinegar and black pepper. Taste and adjust the seasoning with more kosher salt if needed—this is where you can really make the soup sing.
For the final touch, slowly whisk in the heavy cream until fully incorporated. The cream should warm through but not curdle—keep the heat at a gentle simmer. The soup should now have a perfect balance of smoky, sweet, and tangy flavors with just a hint of richness from the cream. This is the moment where all your hard work pays off.
Serve with Crusty Bread
Ladle the warm soup into bowls and serve immediately with the crusty bread on the side. The bread is perfect for soaking up every last drop of that velvety, flavorful broth. The contrast between the warm soup and the crisp bread makes each bite even more satisfying.
This soup tastes even better the next day as the flavors continue to develop. If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. When reheating, warm gently on the stove—never microwave, as it can break down the delicate texture. Enjoy your homemade smoky-grilled tomato soup!
Pro Tips For Making 110 Grill Tomato Soup
- CHAR THE TOMATOES FIRST: Split the Roma tomatoes lengthwise and grill them cut-side down on high heat for 3-4 minutes—until they blister and darken slightly. I used to skip this step, thinking it was just for show, but it concentrates the sweetness and deepens the flavor in ways blending never does. (Yes, even if you’re impatient like me, resist the urge to rush this.)
- PEEL THE GRILLED SKINS: After grilling, let the tomatoes cool for 2 minutes, then slip off the skins—this is where the smoky magic lives. I learned this the hard way by trying to scrape them raw; the skins slide off like silk when they’ve been properly charred. Toss those skins into the pot with the flesh—they’ll add texture and depth.
- SWEAT THE ONION LOW: Cook the diced yellow onion in olive oil over medium-low heat until it’s translucent and just starting to caramelize—about 8-10 minutes. After burning three batches, I finally figured out that high heat turns onions bitter. Let them work slowly, and you’ll taste the difference when you blend it into the soup.
- BLANCH THE GARLIC: Add the minced garlic to the onions in the last 30 seconds of cooking, but don’t let it brown—just until it’s fragrant. I was skeptical until I tried it: raw garlic can taste harsh in tomato soup, and this quick blanch mellows it out perfectly. (Your future self will thank you.)
Pro cooking tips for perfect results
Grill Pan Mastery
Your grill pan is the secret weapon here—it mimics outdoor grill marks without the mess. I use a 12-inch cast-iron grill pan (like the Lodge Pre-Seasoned Grill Pan) because it retains heat perfectly. Preheat it over medium-high heat for 5 minutes until it's screaming hot—this ensures those perfect char lines. A quick test: flick a drop of water on it, and it should sizzle and evaporate instantly. 🔥
Tomato Charring Secrets
For maximum smoky flavor, char the tomatoes cut-side down first to create those beautiful grill marks. I like to use Roma tomatoes because their firm flesh holds up better than softer varieties. After charring, immediately plunge them into ice water for 30 seconds—this stops the cooking process and makes peeling the skins effortless. The charred skins are packed with smoky goodness, so don't skip this step!
Broth Reduction Technique
After adding the broth and herbs, let the soup simmer uncovered for 15-20 minutes. This isn't just about cooking—it's about reducing the liquid to concentrate the flavors. Stir occasionally and taste as you go. If the soup gets too thick, add 2-3 tablespoons of water to loosen it up. The goal is a velvety texture with deep, complex flavor—patience is key here. ✨
Straining for Silky Texture
Use a fine-mesh sieve (like the OXO Good Grips) to strain the soup, pressing gently on the solids to extract every last drop of flavor. Don't rush this step—the more you press, the richer the soup will taste. For an extra-smooth texture, you can even blend the strained solids with a splash of broth and strain again. This technique ensures a luxurious mouthfeel that feels like it took hours to make.
Creamy Finish Tips
When adding the heavy cream, do it slowly while stirring constantly to prevent curdling. Keep the heat at a gentle simmer—never boil. If you're making this ahead, let the soup cool completely before refrigerating. The cream will separate slightly, but a quick whisk before serving brings it back to perfection. For a dairy-free version, substitute with coconut milk and add a pinch of nutmeg for warmth. 💫
Garnish Like a Pro
Fresh basil leaves and a drizzle of extra-virgin olive oil elevate this soup to restaurant quality. For extra flair, add toasted pine nuts or crumbled feta cheese right before serving. I also love a sprinkle of flaky sea salt (like Maldon) for that final touch of sophistication. The key is to garnish just before eating so everything stays fresh and vibrant.

Frequently asked questions
Why does this recipe use a grill pan instead of actual grill?
This method delivers that coveted smoky flavor without needing outdoor equipment. A grill pan replicates grill marks and charring on your stovetop using high heat and ridges—perfect for apartment cooks or anyone who wants restaurant-quality results in 30 minutes. The key is preheating until screaming hot to create those caramelized edges.
Can I make this soup without heavy cream?
For a lighter version, skip the cream entirely or substitute with ½ cup coconut milk for richness without dairy. The soup will still be velvety thanks to the reduced broth. Add a pinch of nutmeg if using coconut milk for warmth. The smoky tomato base carries all the flavor on its own.
How do I prevent the soup from getting too acidic?
The balsamic vinegar adds brightness, but if you prefer less tang, reduce to 1 teaspoon or substitute with ½ teaspoon lemon juice. Taste as you cook—this soup is forgiving. The charred tomatoes provide natural sweetness that balances acidity perfectly. For extra depth, add a pinch of sugar while simmering.
What's the best way to reheat leftovers?
Always reheat gently on the stove over low-medium heat—never microwave, as it breaks down the silky texture. Stir occasionally and add 1-2 tablespoons of water if it thickens too much. The soup actually improves overnight as flavors meld further. Store in an airtight container for up to 4 days.
Can I use canned tomatoes instead of fresh?
While fresh Roma tomatoes give the best texture, you can use 1 (28 oz) can crushed tomatoes in a pinch. Skip the charring step and add 1 teaspoon smoked paprika to mimic smokiness. The soup will still be delicious but with slightly less depth. For extra richness, stir in 1 tablespoon tomato paste while simmering.
