What Are Fire Roasted Tomatoes?
Fire roasted tomatoes are fresh tomatoes that have been charred or roasted over high heat, either on a grill, in an oven, or on a stovetop. The high heat brings out their natural sweetness, adds a smoky flavor, and creates a slight caramelized char on the skin.
Unlike regular cooked or canned tomatoes, fire roasted tomatoes have:
- A deeper, more complex flavor
- Slightly smoky, roasted notes
- A rich texture that works perfectly in sauces, soups, stews, or as a topping
You’ll often see them used in:
- Pasta sauces for added depth
- Soups and chili for a smoky undertone
- Pizza or bruschetta toppings
- Substitute for canned tomatoes when you want fresh, bold flavor
💡 Fun Fact: In French culinary terms, roasting intensifies the natural sugars in the tomatoes while giving a flavor reminiscent of a traditional wood-fired grill — without needing a grill at all.

Best Tomatoes For Roasting
I have a deep affection for this recipe and have tried roasting all kinds of tomatoes — from cherry tomatoes to beefsteak and Italian plum Roma tomatoes. But nothing compares to the flavor of fresh, pulpy tomatoes — they remain my all-time favorite.
Pulpy tomatoes develop an incredible roasted flavor that perfectly balances natural sweetness and savory depth. When combined with garlic, olive oil, and herbs, the flavor intensifies, creating a rich, aromatic dish that’s hard to resist.
💡 Tip: For the best results, choose tomatoes that are ripe but firm. Roma or plum tomatoes are ideal for roasting because they hold their shape, release less water, and produce a beautifully concentrated flavor. Cherry tomatoes work great for quick roasts or skillet methods.
Ingredients
Tomatoes: Choose ripe, pulpy tomatoes for the best flavor and texture. Dice them into even pieces for consistent roasting.
Salt & Pepper: Season generously with salt, black pepper, and a pinch of chili powder for a subtle kick.
Garlic: Use garlic powder for a robust flavor, or fresh garlic paste or minced cloves for a more intense garlicky aroma.
Olive Oil: Drizzle olive oil over the tomatoes before roasting. You can also use avocado oil for a slightly different flavor and higher smoke point.
Herbs: Enhance with Italian seasoning, oregano, or fresh herbs. The roasted aroma brings out the full flavor of the tomatoes, making them an irresistible addition to any dish.
How to Make Fire Roasted Diced Tomatoes
There are several ways to make fire roasted diced tomatoes, each bringing its own unique flavor and smoky aroma. Here are four tried-and-true methods:
1. Oven-Baked Fire Roasted Diced Tomatoes
Making oven fire roasted tomatoes is quick and foolproof.
- Preheat your oven to 200°C (392°F).
- Dice the tomatoes and arrange them evenly on a baking tray.
- Season with salt, black pepper, garlic powder, and oregano, then drizzle generously with olive oil.
- Bake for 30–40 minutes, stirring halfway for even roasting.
- Finish with a broil for 10–15 minutes to achieve that perfect golden, slightly charred top.
💡 Tip: Broiling intensifies the smokiness and makes the tomatoes pop in flavor.

2. Grilled Roasted Tomatoes (Skillet or Electric Grill)
You can easily make fire roasted tomatoes on a grill using a stovetop grill pan or electric griller:
- Lightly oil the grill or pan.
- Grill the diced tomatoes over medium heat, turning occasionally to cook evenly.
- Once slightly charred, season with salt, pepper, and a dash of oregano.
💡 Tip: This method takes 5–10 minutes and gives a subtle smoky flavor without an oven.
3. Open Fire Roasted Tomatoes (Stovetop Flame)
For a traditional, rustic flavor, roast the tomatoes directly over a stovetop burner:
- Place whole tomatoes on the flame until the skin chars.
- Dice the roasted tomatoes and season with salt, pepper, and oregano.
💡 Tip: This method is quick, effortless, and gives a true “fire-roasted” aroma reminiscent of outdoor cooking.
4. BBQ Roasted Tomatoes (Charcoal or Gas Grill)
For the ultimate smoky taste, roast tomatoes over a BBQ grill:
- Either thread the tomatoes onto skewers or place them directly on the grill.
- Roast until the exterior is beautifully charred on all sides.
- Dice the tomatoes and season with olive oil and your favorite spices.
💡 Tip: The smoky BBQ flavor makes these tomatoes perfect for salsas, grilled meats, or pasta sauces.

Pro Tips
- Choose the Right Tomatoes: Use ripe, pulpy tomatoes like Roma or plum tomatoes for the best roasted flavor and texture. Cherry tomatoes are great for quick roasts or skillet methods.

- Garlic Matters: Fresh garlic gives a bold flavor, while garlic powder is convenient and still aromatic. Adjust based on your preference.
- Customize Seasonings: Experiment with thyme, oregano, rosemary, or green chilies to make it Italian-style or Mexican-style.
- Don’t Overcrowd the Pan: Spread tomatoes in a single layer to ensure even roasting and caramelization.
- Oven vs. Stovetop: Oven roasting is hands-off and perfect for large batches. Stovetop or grill methods give faster results and a slightly different smoky taste.
- Storage: Let tomatoes cool completely, then store in an airtight container in the fridge for up to 5 days, or freeze for up to 2 months.
- Multipurpose Use: These fire roasted diced tomatoes are perfect as a canned tomato substitute, in pasta sauces, salsas, chili, or as a topping for grilled meats.
