Key to success with winter spinach is planting the seeds early enough so they reach maturity before the first frost. Depending on the variety, spinach will begin to be ready to harvest in 5 to 8 weeks. The easiest way to harvest is to simply cut the entire plant. But spinach will provide an extended harvest if cared for properly. Snip off only the oldest, largest leaves, and the rest of the plant will continue to produce crunchy leaves for your winter stews. That is, if hungry rabbits don’t get to it first.
An alternative method is to cover the plants completely with mulch before winter, which will cause the plants to go dormant. Pull back the mulch as the days warm in early spring to prompt fresh growth. Doing this means you miss the crunchiest, sweetest leaves of winter, but it ensures that you’ll be the first one in the neighborhood cutting spinach in spring.
I get my winter spinach from a farmer in southern Indiana who pulls it out of the dirt the morning I ask for it. Because of its network of veins and crinkled leaves, savoyed spinach will always need thorough cleaning to wash out every last speck of dirt. The best method is to fill a large container with cold water and completely immerse the spinach in it. Move the leaves about to loosen the dirt, which will sink to the bottom. Slowly remove the spinach from the water and drain it on thick towels until completely dry. These are tough leaves, so don’t worry about being gentle. Place them in an airtight container in the refrigerator to keep them fresh for up to a week.
Winter spinach is as versatile as it is flavorful. I love it raw in salads; it is hearty enough to withstand big flavors like bacon, butternut squash, roasted beets, and even warm vinaigrettes. Try substituting it for lettuce in your next turkey sandwich. A quick sauté with garlic, butter, and nutmeg is a classic accompaniment to any winter roast. For a super-fancy garnish, deep-fry it in corn oil, drain it on paper towels, and sprinkle it with sea salt. I eat these like potato chips. But my favorite way to use winter spinach is to add it to stews or rice dishes at the last minute. Spinach is mostly water, which is why it wilts down so much when heated. Adding it to warm dishes last minute as a finishing touch preserves its unique texture and color. It is a wonderful platform to show off this most loyal winter crop.

Winter Spinach Sformato
Sformato, an Italian favorite, is somewhere between a baked custard and a souffle and can be savory or sweet. Most sformato recipes start with a bechamel or white sauce, but I substituted tofu to preserve as much of the clean bright flavor of the spinach as possible.
- 1 teaspoon butter
- 1 clove garlic, finely minced
- 10 ounces spinach, washed and drained
- 5 ounces firm tofu
- 1 1/2 cups whole milk
- 1/2 cup Parmesan cheese
- 1 egg
- 1/2 teaspoon freshly grated nutmeg
- 1/2 teaspoon salt
- 1/8 teaspoon pepper
- Shiitake Vinaigrette (recipe above)
- Thinly sliced radishes (for garnish)
1. Preheat the oven to 375°F. Heat the butter in a large skillet. Add the garlic and saute for 1 minute.
2. Add the spinach a handful at a time, stirring constantly just to wilt all the spinach, about 3 to 4 minutes. Set aside.
3. In a blender, place the tofu, milk, and cheese. Puree until smooth. Add the spinach and egg, and puree again until smooth.
4. Season with the nutmeg, salt, and pepper. This mixture makes 3 1/2 cups.
5. Spray eight 3-ounce ramekins with nonstick cooking spray. Pour in the batter. Place on a pan with a little water on the bottom and bake for 35 to 40 minutes, or until a toothpick inserted into the center comes out clean.
6. Remove from the oven and let cool for at least 10 minutes to ensure they turn out without collapsing. Run a toothpick along the sides to release from the ramekins. Invert onto a plate. Top with the vinaigrette. Garnish with radishes and serve.
