The summer has been much cooler than previous summers, which has been refreshing. Lower energy bills are a perk, and subway and walking commutes are much less sticky. But the lower temperatures mean that my tomatoes have been pokey about ripening. I’m getting impatient! Chances are, as always, as soon as a couple of fruits start ripening, too many will, and I will be scrambling. Before that happens, I stole a few unripened tomatoes from the plant to make this dish.
This is the first time I have tapped into the green tomatoes so early. There are usually some left over on the plant when the first frost creeps in, and I snatch them before my garden is winterized.
I make fried green tomatoes at least once every year. They keep me in touch with my southern roots. Buttermilk dressings and remoulade sauce make excellent pairings. In this recipe, lightly fried tomatoes make the topping of the gratin. It seems to me more like a crustless quiche of Swiss chard and Gruyère cheese with a green tomato topping.
I hope you’re not getting sick of me posting about chard. Remember, you can substitute pretty much any hearty green..spinach, kale, collards, mustard greens, etc. I just happen to have chard again!
Green Tomato and Swiss Chard Gratin
Reproduced from Martha Rose Shulman’s recipe in The New York Times
1 bunch Swiss chard, stems separated from the leaves
1 lb green tomatoes, sliced a little less than 1/2 inch thick
1/2-3/4 Cup cornmeal for dredging, as needed
Salt and freshly ground pepper to taste
3 Tablespoons olive oil
1 onion, chopped
2 large garlic cloves, minced
2 teaspoons fresh thyme leaves, chopped
3 eggs, beaten
1/2 Cup milk
Approx 1/2 Cup or 2-3 ounces Gruyère cheese, grated
Prepare your 2-quart baking dish by spraying it with cooking spray or olive oil.
To blanch the swiss chard leaves, fill a large pot with salted water and bring to a boil. Fill a bowl with ice water. While the water heats, dice the swiss chard stems and set aside to be combined with the chopped onion.
Once boiling, drop the chard leaves in the water and blanch for about 1 minute.
Lift out of the water and transfer to the ice water to stop the cooking. Put the leaves in a colander to drain excess water. Chop and set aside.
Slice your green tomatoes. This is a little tedious with the plum tomatoes–ideally you have abundant round beefsteak or big boys. Season the slices with a little salt and pepper, and add a little salt and pepper to the cornmeal as well.
Dredge the tomatoes in the cornmeal.
Glug 2 Tablespoons of the olive oil in a heavy nonstick pan over medium-high heat. Pan-fry the tomatoes for about two minutes each side, until they are just starting to turn golden. A narrow flexible spatula, like the type used for fish, is helpful for turning over the slippery suckers. When done, transfer to a plate and set aside.
While frying the tomatoes, preheat the oven to 375 degrees.
Add more olive oil to the now-empty pan and pour in the onion and chopped chard stems. Saute for about 5 minutes, until the vegetables soften. Add a pinch of salt, some grinds of pepper, and your minced garlic.
Cook for about a minute, and then finally add the thyme and chopped chard. Stir everything together over medium heat for another minute. Good luck keeping it in the pan as your stir! Taste the mixture and add salt and pepper.
In a large bowl, whisk the 3 eggs with a generous pinch of salt and freshly ground pepper. Pour in the milk, stir, and then add the cheese and chard and stir. Pour into your baking dish.
Layer the tomatoes over the top.
Transfer to the oven and bake for 30 to 40 minutes. The gratin is done when the eggs are set and it is beginning to brown.
This makes a generous 6 servings, so I will be enjoying it all week!
