Fried green tomatoes are beloved for good reason — the combination of tart, firm tomato and crispy cornmeal coating is genuinely excellent. But grilled green tomatoes are something different, something arguably more interesting, and they deserve far more attention in the world of grilling recipes.
On the grill, the green tomato’s firm flesh holds up beautifully without disintegrating. The natural tartness concentrates as moisture evaporates. The grill adds char marks and smoky depth. And the slightly bitter, almost herbal quality of the unripe tomato becomes a feature rather than a flaw — a bright, acidic counterpoint to everything rich and fatty on the cookout table.
This is the sleeper hit of the grilling season.
Why You’ll Love This Recipe
Texture that stands up to the grill. Red ripe tomatoes fall apart on a grill grate. Green tomatoes — firm, dense, low in juice — hold their shape completely, develop beautiful char marks, and have a satisfying, almost meaty bite.
A natural palate cleanser. The tartness and slight bitterness of grilled green tomatoes cut through the richness of everything else on the table — steaks, burgers, chicken, sausages. They refresh the palate and make the next bite of meat taste better. This is a side dish that earns its place.
Almost zero prep time. Slice, season, oil, grill. This is one of the most effortless grilling recipes in the collection, and it looks and tastes like something that took far more effort than it did.

Cutting slices too thin. Green tomatoes need to be sliced at least 1cm thick — ideally 1.5cm. Thin slices cook through too quickly, losing their structure before they develop proper grill marks. Thick slices give you time to build char on the outside while maintaining a firm, just-yielding interior.
Not oiling the tomatoes directly. Oiling only the grill grates isn’t sufficient for tomatoes. Brush each slice directly with olive oil on both sides. This ensures even contact with the grill, promotes caramelization, and prevents sticking.
Over-salting before grilling. Salt draws moisture from vegetables. On a green tomato that’s already firm and low in moisture, early salting is fine in small amounts. But heavy pre-salting creates too much surface moisture which steams rather than sears. Season lightly before, more generously after.
Skipping the finishing sauce. Grilled green tomatoes on their own are good. Grilled green tomatoes with a sharp, creamy remoulade or a bright herb vinaigrette are extraordinary. The sauce is not a garnish — it’s an essential component that completes the dish.
Chef’s Notes
My go-to sauce for grilled green tomatoes is a quick Cajun remoulade: mayonnaise, whole-grain mustard, hot sauce, capers, fresh parsley, lemon juice, smoked paprika, and a tiny amount of garlic. It takes 5 minutes to make and it’s the kind of sauce you start putting on everything else on the table.
I also finish the grilled tomatoes with flaky sea salt and a generous drizzle of excellent extra-virgin olive oil. The combination of smoky char, bright tartness, rich olive oil, and flaky salt is one of those elemental flavor combinations that needs nothing else.
For presentation, I fan the slices slightly overlapping on a platter, drizzle the remoulade across rather than under them, and scatter fresh basil leaves and a few capers on top. It’s simple, beautiful, and it communicates instantly that this is food made with intention.
Key Ingredients — And Why They Matter
Green tomatoes (4 large, firm): Unripe green tomatoes — not tomatillos, which are a different thing entirely. Look for completely green, very firm tomatoes. Slightly yellow-green is acceptable. Soft is not.
Extra-virgin olive oil (for brushing): Creates the contact and heat transfer needed for even caramelization. Also contributes its own fruity, peppery flavor to the finished tomato.
Flaky sea salt and coarse pepper: Applied after grilling for maximum impact — the crystals crunch against the soft interior of the tomato and the seasoning hits the palate immediately.
Smoked paprika (light dusting before grilling): Adds a secondary layer of smokiness and a beautiful deep orange color to the char marks.
For the remoulade: Mayonnaise, whole-grain mustard, hot sauce (Tabasco or Crystal), capers, fresh parsley, lemon juice, smoked paprika, garlic powder.
To finish: Fresh basil, capers, extra-virgin olive oil.
How to Make Grilled Green Tomatoes
- Make the remoulade. Combine 4 tbsp mayonnaise, 1 tsp whole-grain mustard, 1 tsp hot sauce, 1 tbsp chopped capers, 2 tbsp fresh chopped parsley, juice of half a lemon, ¼ tsp smoked paprika, and a pinch of garlic powder. Mix and refrigerate until serving.
- Slice the tomatoes. Cut into 1–1.5cm rounds. Pat dry with kitchen paper.
- Season and oil. Brush both sides of each slice generously with olive oil. Dust lightly with smoked paprika and a small amount of salt.
- Grill on high heat. Place slices on a hot, clean, oiled grill. Do not move for 3 minutes — let the char marks set completely.
- Flip once. Carefully flip each slice. Grill another 2–3 minutes. The tomato should be charred with visible grill marks but still holding its shape firmly.
- Season immediately off the grill. Transfer to a platter and immediately season with flaky sea salt and coarse black pepper while hot.
- Sauce and finish. Drizzle remoulade across the platter. Scatter fresh basil leaves, a few whole capers, and a final thread of olive oil.
Variations & Tips
Italian direction: Skip the remoulade and top with torn burrata, basil, and a balsamic glaze. The bitter tomato, creamy cheese, and sweet-tart balsamic is a combination of remarkable elegance.
Spicy version: Add ½ tsp cayenne to the olive oil brush before grilling. Finish with sliced jalapeños and a honey drizzle. The sweet-heat-tart combination is outstanding.
Vegan: The grilled tomatoes themselves are already vegan. Substitute the mayo in the remoulade with a good vegan mayo — the result is nearly identical.
Pro tip — grill in a single layer with space between slices. Crowded tomato slices create steam between them, preventing proper char development. Leave at least 2cm between each slice on the grates.
How to Meal Prep
The remoulade keeps refrigerated for 5 days and improves as the flavors meld. Green tomatoes are best grilled fresh — the texture suffers when reheated. However, grilled green tomatoes served at room temperature are excellent, making this an ideal dish for buffet-style entertaining where food sits for a period before serving. Slice and season tomatoes up to 2 hours before grilling and keep covered at room temperature.
Cultural Context
Green tomatoes have been a feature of Southern American cooking since the 18th century, when tomatoes — introduced to North America from Central and South America — were first cultivated in the warm climates of the American South. Before refrigeration and year-round transport, green end-of-season tomatoes that wouldn’t ripen before frost were a practical ingredient born of necessity.
The cultural moment that brought green tomatoes to national consciousness was the 1987 novel and 1991 film “Fried Green Tomatoes,” which embedded the dish permanently in American culinary mythology. The grilled version represents a contemporary evolution of that tradition — same ingredient, same Southern spirit, different fire.
