One evening this week, the grocery bag was heavier than usual — two pounds of tomatoes, the kind that smell like summer the moment you tear the bag open. I wanted something warm on the table but didn’t have energy for a full production, so I did what I do: I put them in the oven with olive oil, garlic, a little balsamic, and called it dinner’s side.
That’s the whole thing. Roasted tomatoes are an easy and delicious side dish, and this version takes about 15 minutes from start to finish. They come out sweet, juicy, and slightly caramelized, with savory garlic, fragrant basil, and a hint of tangy balsamic in every bite. Roasting concentrates the tomatoes’ natural sweetness, so you get a rich, savory side with almost no effort.
Why this recipe works
These tomatoes are the kind of dish that sounds like a side and behaves like a small feast. I’ve served them next to grilled chicken, tossed them with egg noodles, and spooned them over crusty no-knead bread. The 10-minute cook time for small tomatoes means the oven is barely warm before they’re done — that’s the Tuesday test, and this one passed.
Ingredients
- 2 to 3 pounds ripe tomatoes
- 1 tablespoon olive oil
- ½ tablespoon balsamic vinegar
- 1 clove garlic, minced
- 1 tablespoon chopped fresh basil (or ½ teaspoon dried basil)
- 2 tablespoons shredded Parmesan cheese, optional
- Salt and pepper to taste
Serves 6. Total time: 15 minutes. Method: oven roasted. All you need is a rimmed baking sheet or dish.
A few notes on the ingredients
Tomatoes: Choose the ripest tomatoes you can find — ripe fruit makes the biggest difference in flavor. Roma tomatoes are meatier and may need a few extra minutes in the oven, while cherry, grape, and Campari tomatoes roast more quickly and become wonderfully juicy.
Balsamic vinegar: A splash of balsamic adds a subtle tang and enhances the tomatoes’ natural sweetness. For a sweeter, richer finish, drizzle with balsamic glaze after roasting so it doesn’t over-reduce in the oven.
Garlic: Minced garlic adds bold, savory flavor as the tomatoes roast. Want it milder? Substitute garlic powder, or roast a few whole smashed cloves alongside the tomatoes.
Basil: Fresh basil gives a bright, garden-fresh flavor, and dried basil is a perfectly good substitute when fresh isn’t available. Oregano, thyme, parsley, or Italian seasoning all work too — and a pinch of crushed red pepper flakes before roasting adds a little heat if you like it.
Parmesan (optional): A sprinkle adds a salty, nutty finish. Leave it out entirely if you prefer them plain.
How to make roasted tomatoes
Preheat the oven to 450°F. Wash the tomatoes and cut them in half — if they’re large, cut them into quarters so everything cooks at the same pace.
In a bowl, toss the tomatoes with the olive oil, balsamic vinegar, garlic, basil, Parmesan if you’re using it, and salt and pepper to taste.
Spread them in a single layer on a rimmed baking sheet or in a baking dish. A single layer matters: crowded tomatoes steam instead of roast. Roast for 10 to 20 minutes, or to your desired doneness. Smaller, riper tomatoes like Campari are done in about 10 minutes; larger or firmer ones like Romas run closer to 20. Once cooked, they can sit and be served hot or at room temperature.
Tomato roasting tips
- Cut tomatoes evenly. Quarters for large tomatoes, halves for small ones — even pieces cook at the same pace.
- Don’t toss after roasting. Tossing them around makes them too soft and too juicy. Use a spatula, or just serve straight from the pan.
- Time the basil to your taste. Add fresh basil after roasting for a brighter flavor, or before roasting for a more mellow herb flavor.
Storing leftovers
Save every spoonful. Keep leftovers in an airtight container in the refrigerator for up to 4 days, or in the freezer for up to 3 months. Thaw in the refrigerator, then reheat in the microwave or in a skillet over low heat. They’re also perfectly good cold or at room temperature, spooned over toast with a little extra olive oil.
One serving comes in around 56 calories with 6g of carbohydrates, 1g of protein, and 3g of fat — the rest is mostly summer in tomato form.
If you want more to do with fresh tomatoes, my other favorites are a simple tomato salad, bruschetta, tomato mozzarella salad, and a tomato pie for when you’re ready to go all in.
A note from Nora
The first time I made these, I panicked halfway through and flipped the pan with a spatula, thinking they needed turning. They didn’t. They got a little soft, and Sam said they were “fine, honestly” — which from him is a standing ovation. Since then I’ve learned to leave them alone, and honestly, that’s a life lesson worth roasting a tomato to. If I can make it on a Tuesday, it’s a keeper.
