In the Northeast, where I live, we’re fast approaching my favorite time on the food calendar: tomato season. This past weekend my weekly farmers’ market had a few heirloom tomato varieties on offer with hefty price tags (and rightly so — the first of the season is a big deal!). But within the next two or three weeks, tomato plants will be pumping out their bounty, more and different varieties will start to come in, and the buying (and eating!) frenzy will begin.

How to buy tomatoes

When I shop, I always try to spend a few minutes speaking with the farmers. Who knows better than they do how to select and store fruits and vegetables? Over the years, I’ve picked up some seriously helpful tips.

The #1 piece of advice I receive from farmers at the market? Don’t squeeze the tomatoes! You risk bruising the delicate flesh, and if you then put it back, do you really think the next person will want to buy it? Instead, look for these markers of deliciousness.

  • The color should be bright and vivid, unless it’s an heirloom variety with a naturally dusky appearance.

  • Pick up the tomato gently and take a sniff. It should be aromatic and distinctly tomatoey.

  • Consider how it feels in your hand. A tomato that feels heavy for its size will be nice and juicy.

  • With cherry and grape tomatoes, look for firm skin and intense color. No puckers or wrinkles!

How to ripen tomatoes

Once you get the tomato crop home, you’re faced with what to do with it. If the tomatoes are still quite firm and don't have much fragrance, you can ripen them.

  • Store unripe tomatoes at room temperature, in a single layer, stem side down. That helps them retain all their juices while they ripen.

  • You know a tomato is ripe when it feels somewhat soft and smells fragrant. Just how soft depends on the type of tomato — heirloom tomatoes tend to be softer than roma tomatoes, for example.

How to store tomatoes

Let's say you happened to get overeager at the market, or your home garden is going gangbusters. (Let’s hear it for mulch, disease resistance, superior cultivars, and all the things gardeners geek out about!) Now you are faced with more tomatoes than you can use in the near term. You've got options.

  • How long do tomatoes last? Ripe tomatoes only keep one to two days before they become mushy, overripe blobs, so you need to eat, refrigerate, freeze, or can them.

  • How to tell when tomatoes are bad. If tomatoes are squishy, moldy, and/or oozy, they are bad and you should send them to the compost bucket.

  • Can you refrigerate tomatoes? In short, yes. I heard for years that you should never refrigerate a tomato, because the cold air would turn it mealy and flavorless. According to scientists, there’s some truth to that. But it’s more complicated than a blanket “never refrigerate tomatoes” statement. The cold will extend their shelf life and keep them from ripening further. It does affect their flavor, though, so let refrigerated tomatoes come to room temperature before you use them.

  • Can you freeze tomatoes? Yes, freezing tomatoes is a good idea! But bear in mind they will get mushy once they're thawed, so plan to use them for cooking. Remove the peels (see how to blanch tomatoes, below). Then pack them in airtight containers, leaving about 1/2 inch headspace, and freeze up to 1 year.

  • How to blanch tomatoes. If you want to know how to peel tomatoes, it's the same thing as blanching. Bring a pot of water to a boil, add tomatoes, and boil until their skins loosen easily with the tip of a knife, usually 15 to 30 seconds. Then transfer the tomatoes to ice water until they're cool enough to handle. Now you can easily pull off the peels.

  • How to can tomatoes. Despite their sweet-tart flavor, tomatoes are considered a low-acid food. Canning is easy, but it's important to follow USDA guidelines to prevent botulism. Add 2 tablespoons lemon juice per quart and boil the jars of tomatoes in a water bath for 45 minutes. This recipe for How to Can Tomatoes takes you through all the steps.

The basics: How to slice and dice tomatoes

Do you have a super-sharp knife? If so, slicing and dicing tomatoes is a breeze. If not, reach for a serrated knife such as a steak knife or small bread knife to avoid mashing the tomatoes as you cut through the skin.

  • How to slice tomatoes. Set a tomato on its side and simply cut through to create round slices. Cutting the tomato horizontally like this will give you pieces with both skin and juicy interior that hold together for topping a burger.

  • How to dice tomatoes. First cut wide slices. Then stack a few slices at a time and make parallel cuts. Turn your knife 45 degrees and make a second set of parallel cuts to create small pieces.

Health benefits of tomatoes

Wondering about tomatoes' nutrition? Tomatoes are an excellent source of the antioxidant lycopene, a type of carotenoid (pigment) that gives them their bright red color. They're also a good source of vitamin C and potassium.

Types of tomatoes

Tomatoes (Solanum lycopersicum), a member of the nightshade family, originated in South America thousands of years ago. And while there are thousands of different varieties of tomatoes, the basic ones we have in the marketplace are heirloom tomatoes, beefsteak tomatoes, plum tomatoes or roma, and cherry tomatoes or grape. Read on to learn more about them and how to enjoy them in recipes.

Heirloom tomatoes

When I was a kid, heirloom tomatoes didn’t exist. Well, they existed, but mostly in people’s private vegetable gardens. I didn’t experience the glory of a perfect heirloom until I was well into adulthood. Now, they’re all I think about this time of year — Brandywine, Cherokee Purple, Green Zebra, Mortgage Lifter, Black Krim — even the names are alluring. Rather than a specific type of tomato, “heirloom” simply indicates an older, non-hybrid tomato variety, one that hasn’t been cross-bred to make it uniform and suitable for early harvest and shipping. This means they’re more delicate than supermarket types, and usually more flavorful. Some varieties are suitable for cooking, but I mostly eat them raw, to let the tomato flavor really shine.

Heirloom Tomato Salad with Basil, Capers and Feta

With spectacular tomatoes, it takes very little effort to make a memorable salad. In this one, large heirloom tomatoes and cherry tomatoes meet up with salty feta, chopped herbs, and briny capers. A mix of colors — red tomatoes, yellow tomatoes, and green tomatoes, say — makes this especially stunning, with no extra effort. Add some sourdough toast to sop up the exquisite tomato juices, and I could eat this all summer.

Heirloom Tomato Panzanella Salad

Speaking of bread sopping up the juices, have you ever tried panzanella? When I have ripe tomatoes and just-past-fresh bread, nothing makes me happier. It takes a little more time than a regular ol’ salad, since you toast the bread a bit first and then let the mixture sit and infuse the crunchy cubes with sweet-acidic-sharp flavors. Add some leftover chicken, fresh mozzarella, or other protein, and it’s a complete meal.

Heirloom Tomato Crostini

Yummly Original

Think of this as the best easy summer tomato recipe you'll eat: Toast brushed with extra-virgin olive oil, slathered with garlicky ricotta cheese, topped with sliced heirlooms, a drizzle of balsamic vinegar, and fresh basil. With so few ingredients, those perfectly ripe heirloom tomatoes will really shine.

Heirloom Tomato Tart 

At the height of summer, I don’t want to spend a lot of time with a hot oven. Which is what makes this tart so ideal: You’re only baking the puff pastry crust for about 15 minutes, then spreading on a ricotta-basil-lemon filling. Top it all off with oodles of sliced heirlooms and a simple garnish. Ta-da, it’s ready!

Beefsteak tomatoes

When you picture a tomato, odds are a large fruit called a beefsteak pops into your mind. These slicing tomatoes are what you turn to when you’re looking to top a burger or add flavor to a grilled cheese sandwich. They’re large and meaty so they can stand up to a lot, but they also have a lot of juiciness, which can make sauces or soups too watery. 

Tomato, Peach, and Corn Salad

Tomato is a fruit, so it’s no surprise that it pairs beautifully with other fruits. Here, peaches and fresh-cut corn combine for a simple, sweet, and flavorful salad. Tangy feta on top keeps it from going too far towards sweetness.

Pasta with Marinated Tomatoes and Mozzarella 

On a hot summer night, it’s hard to beat the ease of a no-cook pasta sauce. This one calls for nothing more than diced beefsteak tomatoes, a little bit of sweet onion, fresh mozzarella, and basil. It should be on the table in under 30 minutes. 

Simple Stuffed Tomatoes

The word “simple” is in the name of these beauties, but the flavor is anything but. Italian sausage, scallions, baby spinach, and feta get mixed with cooked orzo, then stuffed inside scooped-out beefsteaks and baked. You wind up with something that feels both sophisticated and old-school, in the best way.

Slow Roasted Tomatoes

Turn to this recipe when your impulse control fails and you come home with too many cherry tomatoes. Cut them in half, season with truly basic ingredients, douse with olive oil, and roast. The juices cook out, the flavor intensifies, and you’ve got something so delicious you can pretend you bought all those tomatoes on purpose. Pop ‘em in the freezer for whenever you need a hit of summer.

Plum or roma tomatoes

Oblong, with thick skins and solid, meaty flesh, plum tomatoes (also called paste tomatoes) are the classic option for sauce, and are what’s inside cans. All this makes them great for cooking — but it also makes them perfect for raw dishes where you want something less watery than a beefsteak. Famous San Marzano tomatoes, traditionally grown at the base of Mt. Vesuvius in Italy, are an especially sweet, low-acid, and meaty plum tomato.

Authentic Gazpacho

Cold, refreshing gazpacho is one of my favorite ways to use up a bunch of ripe plum tomatoes. Two pounds go into the blender along with some cucumber, bell pepper, red onion, and garlic. The whole thing gets whirred together, with olive oil adding richness and sherry vinegar adding a burst of acid. 

Roasted Roma Tomato Sauce

Roasting brings out the umami in plum tomatoes. This one extra step leads to a sauce that’s so intensely tomatoey, you’ll want to eat it right out of the pot. 

Pico de Gallo

This fresh tomato salsa works beautifully with plum tomatoes, because their firm texture won’t lead to a watery mess. Is there anything sadder than a salsa that weeps so much it softens your tortilla chips? With so few ingredients, make sure your tomatoes are fully ripe.

Cherry or grape tomatoes

When I need tomatoes in the off-season, I turn to the bite-sized varieties. They’ve got the most tomato flavor year-round. This time of year, though, I mostly opt for cherry tomatoes — in particular, deeply flavored varieties like Sun Gold. Round cherry tomatoes are more delicate than their grape-shaped cousins, with considerably more juice. In this category you'll also find tiny pear tomatoes, and a variety of nontraditional colors like black cherry. Use them raw for snacking and in salads, roasted, or sauteed until they burst.

Steak Kebabs with Chimichurri 

Grape and cherry tomatoes make excellent fodder for skewers. They’re self-contained so you don’t need to chop anything, and they can hold their own against a flame. Here, they add a sweet, juicy contrast to beefy steak and intensely herbal chimichurri sauce.

Marinated Cherry Tomatoes 

A brief soak in a mixture of olive oil, red wine vinegar, lemon juice, onion, and garlic elevates humble little cherry tomatoes into a versatile condiment superstar. They’ll dress up even the most ho-hum chicken breast.

Blistered Cherry Tomatoes

Cumin seeds add a surprising pop to this easy appetizer. Toss the tomatoes with those seeds plus some other simple seasoning and roast, then broil to give them a bit of char. Serve them over lemony yogurt with bread for scooping.

Easy Whitefish with Burst Cherry Tomatoes 

I can’t get over how easy and yet special this recipe turns out to be. Crisp up the skin of white fish fillets in a skillet, then add cherry tomatoes and lemon wedges and slide it under the broiler. That direct heat bursts the tomatoes and caramelizes the lemon, making an instant sauce for the flaky fish.

Bonus: mix-em-up tomatoes

Sometimes the bounteous displays overwhelm my good judgment and I come home with gorgeous specimens of all shapes, colors, and sizes. Their differing water contents and skin types can make it challenging to use all the tomato types together, but where there’s a will there’s a way, right?

Summer Tomato Salad

When summer tomatoes are at their peak, you really don’t need much more than a drizzle of good olive oil, some flaky salt, and a few grinds of pepper. That said, I love to liven things up a little — like with this salad, which tosses several pounds of mixed tomatoes with a white balsamic vinaigrette, then tops them with quick pickled onions and peppery microgreens. 

Homemade Ketchup

Of all the tomato products on the market, ketchup may be the most common, and the most forgettable. All that changes when you make your own ketchup from scratch. Onion, a little fresh ginger, garlic, and chili, and a balance of brown sugar and vinegar simmered with tomatoes make this a memorable topper. (Overachievers: How about trying homemade tomato paste?)

Fresh Tomato Marinara Sauce 

Here’s a clever way to get around the different cooking times and textures of mixed tomatoes: This recipe has you slowly cook down whatever kind of tomatoes you have, as long as it adds up to 8 cups of chunks. When it’s all broken down and thickened, an immersion blender takes care of the skins — you wind up with a fresh-tasting, versatile sauce that you can use right away or freeze for those cold winter months. 

Fresh Tomato Puttanesca Pasta Sauce

I love the briny, pungent flavor of a long-simmered puttanesca sauce. This version cuts to the chase in just 30 minutes. To make it, you saute garlic, red pepper flakes, and anchovy paste, then stir in chopped cherry tomatoes, olives, and capers and simmer briefly. The dish is basically ready in the time it takes to cook a pot of pasta. Perfect for a hot summer night!
