Soups & Stews
This 110°F grill tomato soup delivers restaurant-quality depth without needing a grill—just a stovetop and a few smart techniques. The secret lies in charring tomatoes over direct heat (or under a broiler) to unlock their natural sweetness and smoky complexity, then simmering them into a velvety, aromatic soup. After years of perfecting this method, I’ve streamlined it for home cooks while keeping that unmistakable grillhouse character.
The beauty of this recipe is its adaptability: grill tomatoes on a gas stove’s high flame, under a broiler, or even in a cast-iron skillet for that signature caramelized edge. Once blended with garlic, onions, and a splash of red wine, the soup develops layers of umami and acidity that balance perfectly. The result? A rich, smoky tomato base with just enough brightness to keep it vibrant—not heavy, not one-note, but deeply satisfying.
What you’ll end up with is a soup that tastes like it simmered all day but comes together in under an hour. The texture is velvety yet structured, with pockets of smoky intensity from the charred tomatoes. Serve it with crusty bread for dipping or a sprinkle of fresh basil to brighten the flavors further. This isn’t just tomato soup; it’s a flavor experience that rivals any grillhouse classic.
Best of all, the technique scales effortlessly—double the batch for leftovers or halve it for a quick lunch. The key is patience in the charring step; don’t rush it. Trust the process, and you’ll have a soup that’s worth every minute of attention. Let’s get started on creating that smoky depth without the grill.
Ingredients for 110 grill tomato soup
Fourteen ingredients transform into restaurant-quality smoky tomato soup without needing a grill.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Roma Tomatoes 🍅 | 4 whole | Halved lengthwise for charring |
| Yellow Onion 🧅 | 1 whole | Diced, medium size preferred |
| Garlic Cloves 🧄 | 4 cloves | Peeled, smashed for infusion |
| Dry Red Wine 🍷 | ½ cup | Bold variety like Cabernet |
| Chicken Stock 💧 | 2 cups | Low-sodium preferred |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For charring tomatoes |
| Canned San Marzano Tomatoes 🍅 | 1 14.5 oz can | Crushed by hand |
| Fresh Basil Leaves 🌿 | ¼ cup | Chopped for garnish |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Peppercorns 🌶️ | ½ tsp | Freshly cracked |
| Balsamic Vinegar 🍶 | 1 tbsp | For brightness |
| Crusty Bread 🍞 | 4 slices | For serving |
The tomatoes are the heart of this soup—Roma tomatoes have the best balance of sweetness and acidity. Heirloom varieties from farmers markets add even more depth, but grocery store Romas work perfectly too. Look for firm, vibrant tomatoes with no soft spots. For the charring step, high heat is critical—whether you're using a gas stove's flame, a broiler, or a cast-iron skillet. The goal is to get those tomatoes blistered and slightly blackened in spots, which unlocks their natural sugars and smoky flavor. I always use a mix of fresh tomatoes and canned San Marzano for consistency—the fresh ones add texture while the canned provides acidity.
No red wine? Substitute with extra chicken stock plus 1 tbsp balsamic vinegar—it'll still give you that depth, just with a slightly different profile. Fresh basil is ideal for garnish, but dried basil at one-third the amount works in a pinch. For the olive oil, avoid light or refined oils—extra-virgin with a peppery finish adds complexity. The balsamic vinegar might seem like an afterthought, but it's what cuts through the richness and keeps the soup bright. If you're making this ahead, add the fresh basil just before serving so it stays vibrant. And trust me on the kosher salt—it dissolves more easily than table salt, so you'll get better flavor control.
This soup tastes even better the next day as the flavors meld together. Store it in an airtight container in the fridge for up to 5 days. For freezing, portion it into 2-cup servings—it reheats beautifully, though you might want to add a splash of water or stock if it seems too thick. The crusty bread should be served fresh—baguettes from a good bakery stay crisp for about 2 days if wrapped in a towel. If you're making this for a crowd, double the batch—it reheats just as well, and the charring technique scales perfectly.

Step-by-step instructions for smoky grill tomato soup
This method delivers restaurant-quality grillhouse flavor without setting foot near a grill.
Char the Tomatoes for Smoky Depth
Preheat a grill pan or cast-iron skillet over high heat until it's screaming hot. Cut the 4 whole large Roma tomatoes in half lengthwise, removing the cores. Place them cut-side down on the pan and let them char for 2-3 minutes until blackened in spots with visible grill marks. Flip and char the other sides for another 2 minutes.
Watch closely—the tomatoes should develop deep char lines while remaining intact. If they start to break apart, reduce heat slightly. The charred skin is what carries that smoky grillhouse essence into your soup. Transfer the charred tomatoes to a cutting board and let them cool slightly before handling.
Build the Flavor Base with Aromatics
In the same pan (no need to clean it—the browned bits are flavor gold), add the 0.25 cup extra-virgin olive oil and let it heat until shimmering. Add the diced yellow onion and cook for 4-5 minutes until softened and golden. Stir in the 4 peeled, smashed garlic cloves and cook for another 30 seconds until fragrant but not browned.
Here's where the magic happens: Pour in the 0.5 cup dry red wine and scrape up all those delicious browned bits from the bottom of the pan. Let it simmer for 2-3 minutes until reduced by half. This deglazing step captures all the caramelized flavors that would normally get lost in the trash.
Simmer the Tomato Mixture
Add the charred tomato halves, the 1 14.5 oz can San Marzano tomatoes (crushed by hand), and the 2 cups chicken stock to the pan. Bring to a gentle boil, then reduce heat to medium-low and let it simmer uncovered for 15-20 minutes until the tomatoes break down and the soup thickens slightly.
Season with the 1.5 teaspoons salt and 0.5 teaspoon freshly cracked black peppercorns. Stir in the 1 tablespoon balsamic vinegar for a touch of brightness that cuts through the richness. Taste and adjust seasoning—this is where you'll see if your charring and deglazing paid off with that deep, smoky flavor.
Finish with Fresh Basil and Serve
Remove the soup from heat and stir in the 0.25 cup chopped fresh basil leaves. Let it steep for 5 minutes to infuse the basil's freshness into the soup. For a silky texture, use an immersion blender to purée until smooth, or carefully transfer to a countertop blender in batches.
Ladle the soup into bowls and serve immediately with the 4 slices crusty bread on the side. The bread will soak up every last drop of that smoky, velvety goodness. The soup should have a rich, tomato-forward flavor with subtle smokiness from the charred tomatoes and a touch of wine's acidity to balance the richness.
Pro Tips For Making 110 Grill Tomato Soup
- CHAR THE ONIONS FIRST: I learned this the hard way—sweating onions low and slow until they’re translucent and just starting to caramelize (about 8-10 minutes) builds flavor that’ll carry through the whole soup. Skip this, and your wine and stock will taste like they’re playing second fiddle to raw onion.
- GRIDDLE TOMATOES UNTIL BLISTERED: Crank that grill to medium-high and let the Roma tomatoes sit until they’re blackened in spots—charred skin means deeper, smokier flavor. I used to flip them too soon; now I leave them be for 5-7 minutes per side, skin-side down first. That’s where the magic happens.
- DEGLAZE WITH WINE IMMEDIATELY: As soon as you remove the onions and garlic, pour in that red wine right away—the residual heat will help lift all the browned bits from the pan. Let it simmer for 2 minutes before adding stock, or you’ll end up with a watery, wine-flavored broth instead of a rich base.
- STRAIN OR DON’T—KNOW THE RISK: If you strain the soup for silky texture, save the tomato pulp and stir it back in at the end for body. I skip straining entirely when I’m lazy, but the soup turns out thicker and heartier—just blend it briefly if you prefer smoothness. No shame in either choice.
Essential equipment for this dish
Grill Pan Essentials
My go-to for charring tomatoes is a 12-inch cast-iron grill pan from Lodge—it heats up fast and retains heat like a dream. The ridged surface gives those tomatoes perfect grill marks while preventing them from sticking. If you don't own one, a stainless steel grill pan works too, though it won't hold heat as well. For stovetop charring, I avoid non-stick pans—they won't get hot enough to create that smoky depth. 🔥
Broiler Alternative
No grill pan? No problem. Use your oven broiler for the same effect! Preheat the broiler to its highest setting and place the tomato halves on a baking sheet lined with foil. Keep them about 3 inches from the heat source and watch closely—you'll get those charred spots in 2-3 minutes. The key is proximity: if your oven has adjustable racks, move them closer for more intense charring. Just don't walk away—broilers can turn tomatoes to ash faster than you think!
Immersion Blender Must-Have
An immersion blender is non-negotiable for this recipe. I swear by the Ninja QN401—it handles hot liquids safely and blends the soup right in the pot, preventing messy transfers. The variable speeds let me control the texture: low speed for chunky bits, high speed for silky smoothness. If you're blending in batches, use a countertop blender with caution—hot liquids can cause steam explosions. Always let the soup cool slightly first, and never fill the blender more than halfway. 💫
Cast-Iron Skillet Backup
When I'm in a pinch, I use my heavy-duty cast-iron skillet (like my trusty Le Creuset) for charring. The secret is getting it screaming hot—I let it sit on the burner for 5 minutes before adding the tomatoes. The extra weight helps distribute heat evenly, giving you consistent charring. Just be patient: cast iron takes longer to heat up but delivers that authentic grillhouse flavor when done right. Pro tip: Let the skillet cool completely before washing—sudden temperature changes can cause cracks.
Optional Tools for Perfection
For extra precision, I keep a meat thermometer handy to check the pan's temperature—it should read 450°F+ for proper charring. A fine-mesh strainer comes in handy if you want to remove tomato skins after blending for a smoother texture. And don't skip the microplane for fresh black pepper—it releases more aromatic oils than pre-ground pepper. These aren't must-haves, but they elevate the dish from good to restaurant-quality. 💡

Frequently asked questions
Can I make this soup without charring the tomatoes?
The charring step is what gives this soup its signature smoky depth, but you can still make a delicious version without it. For a similar effect, roast the tomatoes at 425°F for 15-20 minutes until caramelized. The flavor will be less intense but still rich. If you're short on time, simply sauté the tomatoes with olive oil until softened before adding them to the soup.
What if I don't have red wine? Can I still make this?
The wine adds depth, but you can substitute with 0.5 cup extra chicken stock plus 1 tbsp balsamic vinegar for a similar tangy profile. For a non-alcoholic option, try 1 tbsp tomato paste plus 1 tbsp apple cider vinegar. The soup will still be flavorful—just slightly different in complexity.
How do I prevent the soup from being too acidic?
If you're worried about acidity, balance it with a touch of sweetness. Add 1 tsp honey or maple syrup at the end or use 1 extra Roma tomato (uncharred) in the blend. For extra richness, stir in 1 tbsp heavy cream or coconut milk when serving. The key is to taste as you go—adjust gradually to find your perfect balance.
Can I make this soup ahead of time?
This soup actually tastes better the next day as flavors meld! Store it in an airtight container in the fridge for up to 5 days. For freezing, portion into 2-cup servings—it reheats beautifully. Just add a splash of water or stock if it seems too thick after reheating. The charred tomato flavor intensifies overnight, making leftovers even more satisfying.
What's the best way to reheat this soup?
Reheat gently on the stovetop over medium-low heat until steaming, stirring occasionally. For even heating, use a double boiler or microwave in 30-second intervals, stirring between each. Avoid boiling—it can break down the texture. If the soup thickens too much, thin it with a splash of stock or water. Fresh basil should be added after reheating.
