I don’t know that I’ve ever met a tomato recipe I haven’t liked, but there are some that I love more than others. One of my favorite ways to enjoy summer tomatoes is by slow-roasting them in the oven. You can throw these on pizza, on salads, eat them plain or my favorite, on top of some toast with an egg. When you slow roast tomatoes it deepens the flavor and concentrates the sugars. As a result you’re left with delicious jammy little puddles of tomato goodness, and making them couldn’t be simpler! This is even a great way to deal with so-so tomatoes that you buy from the store or the end of the season tomatoes that are ripened indoors and lack the sun-ripened flavor.
You can use any kind of tomato, from cherries to beefsteaks, just keep in mind that the larger the tomato the longer it will take to roast. Roma types that are dry roast quicker so check them earlier, but beefsteaks are more concentrated when roasted so they taste better. If you’re going to roast a batch, you may as well do an entire oven full to save energy and I guarantee you’ll always want more!
All you need to do it is cut the tomatoes in half, lay skin side down on a cookie sheet lined with parchment paper (the parchment helps get them up later). If you want to, drizzle with olive oil and some freshly chopped herbs and sprinkle with salt and pepper, or simply roast as is, it’s up to you, I do both. Roast in a 225 degree oven for 4-8 hours or until reduced in size and slightly moist, cooking time depends on size of tomatoes and your oven. You can try raising oven temp to 250, but you may get some dark spots on the tomatoes, it depends on your oven. I like to put mine in the oven before I go to bed and set the timer for 6 hours. The next morning I check the tomatoes, remove any that are finished and continue roasting any tomatoes that aren’t quite done. You can taste one after 3-4 hours and you’ll be able to tell if it’s done or not. It should taste like concentrated tomato with a slightly sweet tang. If it’s still acidic and sour, roast for a while longer.
These will need to be frozen to preserve them. I usually freeze on the cookie sheets, then store in a large bag. That way can I get one or twenty depending on what I’m making. I like to use slow-roasted tomatoes in my homemade ketchup, I find it adds a wonderful rich flavor and reduces the cooking time. I don’t roast them quite as long as when I do this since it’s much easier to extract the peels and seeds when they’re not quite as dry.
