herbed roasted tomatoes to freeze, with alana chernila (join our new workshops!)

DSC_0010HOW DO YOU STASH TOMATOES for offseason use? Roast them with herbs, then freeze the resulting goodness, says cookbook author Alana Chernila, for a wildly flavorful, versatile staple of year-round cuisine. Alana and I will be hosting a daylong garden-to-table workshop celebrating tomatoes and garlic September 6 at my place—and she joined me on radio this week with such recipes and tips to share.

In 2008, when I was shifting my life from city-dwelling corporate executive to rural dweller, I met Alana Chernila. We aren’t close in age—she’s a mother to two young girls—but I recognized in her right away some common essential elements.

The natural world was the anchor we were both intentionally gravitating back to—and we each were obsessed with having a well-stocked freezer and pantry (or else!). We were also both brewing books. Alana’s “The Homemade Pantry: 101 Foods You Can Stop Buying and Start Making,” has been lavished with praise from food luminaries including Mollie Katzen. She’s about to deliver the manuscript for her second book, “The Homemade Kitchen,” due out in fall 2015.

It was a 30-year-old farmers’ market in Great Barrington, Massachusetts—near where we both live—that guided Alana to become a cookbook author, actually. Alana started working at the Saturday morning market in 2008, a decision that proved transformational.

I’ll let her tell us about her life-changing moment—and about how she stashes tomatoes and more, from our recent radio conversation (listen in here if you like):

my q&a with alana chernila

Alana ChernilaQ. So my life changed in 2008, when I left the city to move north to the garden fulltime. And yours shifted that same year in the local farmers’ market. Tell us.

A. I’d had kids in my 20s, and tried out many different careers—but through a lot of it, I was working at our local farmer’s market, as a working member of Indian Line Farm in South Egremont, Massachusetts, one of the first CSAs in the U.S., helping to pay for my farm share.

I found that it was my favorite thing of anything I was doing: It was a revelation—“Saturday’s my favorite day.” And it was really because it was the first time I’d had an opportunity both to work with vegetables and to get to talk about them, and to figure out how to use them, and experiment with them, and I got to share that with everyone who was coming and trying to figure out how to cook their first garlic scape, and kohlrabi, and all those strange things.

Q. And you started writing as a result, too, right?

A. Yes, that’s really how I came to what I do: I started writing recipes in those first markets, and here I am. So this relationship with food—not just as a CSA member, but as a representative of the CSA at the farmer’s market—also really became the foundation of writing for me, too. I started a blog soon after, called Eating from the Ground Up.

And I started gardening at that time as well, so the early stories on the website were really me finding my way through the kitchen and the garden.

Q. So let’s talk vegetables: When you are selling them at the market–what do people ask about?

A. There are certainly some vegetables that everyone is comfortable with, like lettuce. Everyone knows what to do with lettuce. But people are so different—it has so much to do with where they grew up, or what their parents cooked for them. You’d be surprised how many people I meet who have never tried kale before.

Q. Still? Even though it has become the “it” vegetable?

A. But maybe they grew up eating black radishes with salt, in their Polish grandmother’s kitchen. It’s always a learning experience for me to talk with people about the vegetables in their lives that they’re comfortable with.

Definitely tomatoes are a place where people are comfortable—though the heirlooms offer new lessons. The garlic plant itself confounds people in any other form but the cured bulb, such as the scape, and the greens—that’s really fun to talk to people about.

Q. I saw something new a few years ago at a farmers’ market—not new to me as a gardener, but new to me as a market item: green garlic, or spring garlic. Some growers harvest some of their garlic crop before it bulbs up to the max.

A. Yes. Actually now when I plant it in the fall, I plant it denser than it can grow the next year—with the intention of actually thinning out my garlic in the spring, so that I can have green garlic, because I love it so much.

Q. That brings up a great tip: that you can do the same with onions. You can plant your onions twice as close, then harvest every other one young, before the main crop fully develops.

A. And those spring garlics and young onions are so sweet, and tender. I discovered it by mistake—by planting too tightly at first.

Homegrown heirloom tomatoesQ. You mentioned with tomatoes, that people are sometimes mystified by the heirlooms at the farmers’ market. Any favorites you love to show them?

A. I love the green tomatoes; I have a softness in my heart for them, such as ‘Green Cherokee’ and ‘Green Zebra.’ I talk about them a lot.

The ‘Brandywine’ is your stock heirloom, and widely available, and it’s just so reliably good. That’s usually the one I hand to people when they want to try their first heirloom.

Q. It’s tomato-glut time or thereabouts. But sometimes there aren’t enough at one moment for a whole batch of sauce, so I sometimes just bag them in the freezer, whole, and cook them later. But you have another tactic: roasted tomatoes for the freezer.

the-homemade-pantryA. I wrote about it in the first book, as an alternative to tomato canning. I love canning tomatoes, but of all the things to can, I find it to be the most laborious. And like you I was finding myself with tomatoes on the counter going slightly rotten, or moldy, and thinking, “I have to preserve this right now,” but not having the time to pull out my canning pots.

The only key with the roasted recipe: It can’t be 110 degrees out when you do it, because it uses your oven, so it’s good for the late-summertime when the days are getting cooler.

I either halve or quarter the tomatoes, into manageable sizes, like what you would eat in a tomato salad. I leave the skins on. I lay them out, flesh side up on a parchment-lined baking sheet with a rim to catch all that tomato juice.

The fun part is that you can stop there, or you can add whatever herbs you have growing in the garden, or even some peeled garlic cloves. All of those wonderful things that go with tomatoes. Garlic cloves, rosemary springs, thyme, oregano—whatever you have. And then a little salt and pepper, and you drizzle a little olive oil, and make it look like a work of art.

And then put it in a 275-degree F oven, to slow roast them, for as much time as you have. Three hours is pretty good; five hours is better. You could even do it overnight, but no less than three.

Q. When it’s done—then what?

A. What you’ll find will depend on the water content of your tomatoes. Heirlooms tend to be fairly watery; paste tomatoes less so. What you’ll find is slightly shriveled tomatoes that have released some of their juice. Some will be even closer to sundried tomatoes.

I always do this with a wide variety of different tomatoes—because as a home gardener that’s what I have. So I end up with something slightly shriveled, released juice, a little bit dehydrated, caramelized at the edges. It’s totally delicious right away; you could just pour the whole tray over spaghetti right away.

Q. Almost a sauce?

DSC_0016A. Yes, you can add a little olive oil and use it like a sauce, or spread it on bread—it has all sorts of uses. But what I do to preserve the tomatoes, is let them cool a bit, then tip the tray into freezer bags [left], close them up, and flatten the bags to conserve space in the freezer. Later I take a bag out, and thaw it, and I can sauté an onion and add the thawed tomatoes and I have an amazing sauce. I can also put them in soup—or make an entire soup of them, with a little cream. It’s sort of my secret ingredient in the freezer. I make sure I have lots of bags of roasted tomatoes.

[The original story from Alana’s blog on roasted frozen tomatoes, with more detail, is here.]

Q. I have always made what I call Tomato Junk—my universal solvent for future recipes, that I freeze, too—but I have never roasted the ingredients. I just cook them slightly in a pot first.

A. So you can think of mine as Roasted Tomato Junk—and they’re great for cooking beans, as well, by the way.

our sept. 6 tomato-garlic workshop

Screenshot 2014-07-31 13.28.11IT’S THE BEST OF TIMES: garden- and farm-fresh tomato and garlic season. And it gets even better if you can join me with my friend and hit cookbook author Alana Chernila (“The Homemade Pantry”) for a very special day of food, garden talk, and great company in a small workshop-sized group Saturday, September 6, in Copake Falls, New York.

Limited to 12 people. Breakfast and lunch served; go home with preserved goodies, too, like Alana’s amazing Tomato Jam—plus knowledge for better growing, preserving, and more.

We’ll walk in the garden, and talk plants and food, including where to shop for seed garlic and the best tomato seed, and how to grow and harvest both–even how to create your own strain of a favorite one of each by saving “seed.” In interactive show-and-tell with some hands-on participation, we’ll also learn many great kitchen tactics and recipes. Get all the details, and a ticket.

  1. says

    Margaret this seems the best yet for tomatoes, used to do a lot of freezing and canning but find as I get older, not into that so much so this seems like a wonderful solution.

    Thanks to you and your friend, really appreciate.

  2. Kevin corrigan says

    I have found that dehydrating some is good too. It really concentrates the flavor, and I can store a bunch in Mason jars for use trhroughout the winter. Espacially good added to bread or pizzas too.

  3. Jen Johnson says

    Roasting tomatoes is what I do at home for all the same reasons listed. The only additional step I do is run the finished product through a food mill to remove the skins and a majority of the seeds. I find the result is a bit sweeter. I freeze it it mason jars and give lots away as gifts. By far the best tomato sauce I’ve ever eaten. Yum.

  4. Beverly, zone 6, eastern PA says

    So tempting and so timely.

    There are trays in my mud room with 8 types of ripening tomatoes, picked over several days, just waiting to jump into the oven with some of my own cured garlic and mature onions. Wonderful possibilities! Thanks!

  5. Vanessa M. says

    Very inspiring ideas for tomatoes! I’ve already canned some this month and instead of digging out the canner again; may just roast them. Thanks for the podcast with Alana.

  6. says

    Would love to do this. Still waiting for my tomatoes to turn red. They got a late start this year. May have to make some pickled green tomatoes!

  7. Donna Fellows says

    Hello Margaret: Need your advice. Finished roasting mostly Roma tomatoes (approx. 4 hrs.) with parsley, marjoram, garlic and olive oil last evening. Packaging them for freezer last evening and they almost turned to paste. If I were to make tomato soup, would I use regular tomatoes also? Thanks–I enjoy your website–lots of good information!

  8. JJ Jessee says

    I agree on the green tomatoes. This is my first year with greens and the Cherokee and Zebra are both powerhouses, well behaved plants, and tasty fruit with excellent texture. I’ve got my first trays of the Roasted tomato sauce in the oven -using mostly Jersey Devils and San Marzanos. It smells D.I.V.I.N.E. I’m so done with canning tomatoes.

  9. Betty & Joe Hammang says

    I made these at my son’s in Ohio with ROMA tomatoes..so quick and easy. Did 2 trays at a timeand put some in qrt. Freezer bags and some in Gal. Bags. Love this method.

  10. Joe Doran says

    I used hardneck seed garlic last year for the first time. Should I reorder or use my own cloves. My owl is not working in my veg garden so I will get my toms into the oven. Great idea. Thanks, Joe

    • margaret says

      I replant the largest cloves from the largest heads (and use the others for cooking/eating). That’s how I “select” my own strain of what we cann “seed garlic” (the cloves you replant) that’s adapted a little better each year to my own garden conditions.

  11. Jill says

    I want to try this as I have a lot of tomatoes and we’ve already put up dozens of jars. If I use garlic cloves will they roast as well and not get bitter at this temperature? Just want to make sure before I put it all together. Thanks!

    • margaret says

      Hi, Jill. The garlic will sort of soften and melt, not get crisp, but of course is depends on your oven (if there are hotspots) and how long you roast. You an always remove the garlic cloves — again, use whole cloves — partway through if you think they are “done enough” for you, then return them to he mix after the rest is done.

  12. maryG says

    After reading about Alana’s roasted tomatoes I was inspired and decided to quarter and place my tomatos in a perforated grill pan and set inside my Big Green Egg smoker to dehydrate. As the heat died down, from what ever I had made for dinner that night, they slow cooked to perfection. I left them in the BGE overnight and in the morning ended up with the sweetest tomato pulp with just barely a hint of smoke to them. I filled half pint jars and froze them for pizza sauce this Winter. I am still at it!

  13. says

    For those who choose not to use oil, they still come out delicious without it. It seems silly to buy cold pressed EVOO (which is the best) and then subject it to heat which makes all oils unhealthy.
