Ingredients
Scale
- 2 pounds fresh spinach, tough stems trimmed
- 1 tablespoon olive oil
- 1 small yellow onion, finely diced
- 3 garlic cloves, minced
- 2 tablespoons all purpose flour
- 1 cup 2 percent milk, plus a splash more if needed
- 1/4 cup finely grated parmesan, plus more for serving
- 1/2 cup plain nonfat Greek yogurt, at room temperature
- 1/2 teaspoon fine sea salt, plus more to taste
- 1/4 teaspoon black pepper
- 1/4 teaspoon freshly grated nutmeg
- 1 teaspoon fresh lemon juice (optional)
Instructions
- Place a large dry Dutch oven over medium heat. Add the spinach in big handfuls, turning with tongs as it wilts, 2 to 3 minutes per batch, and move each finished batch to a colander. Work through all 2 pounds.
- Let the spinach cool until you can handle it. Press it firmly in the colander, then pile it on a cutting board and chop it roughly into bite size pieces.
- Squeeze the chopped spinach by the handful over the sink, pressing hard, then squeeze each handful a second time. The spinach is ready when a squeezed ball holds together and no longer drips.
- Wipe out the pot and warm the olive oil over medium heat. Add the onion with a pinch of the salt and cook, stirring now and then, for 4 to 5 minutes, until soft and sweet. Stir in the garlic for 30 seconds.
- Sprinkle the flour over the onion and stir constantly for 1 minute, until the paste smells faintly toasty and coats the bottom of the pot in a thin, pale layer.
- Pour in the milk in a slow stream, whisking as you go. Simmer gently for 2 to 3 minutes, whisking often, until the sauce thickens enough to coat the back of a spoon.
- Lower the heat and stir in the parmesan until it melts completely. Season with the remaining salt, the pepper and the nutmeg, and taste the sauce on its own; it should be well seasoned before the spinach returns.
- Fold the squeezed spinach into the sauce and warm it through over low heat for about 2 minutes, stirring gently. Do not let it boil, which would dull the color.
- Take the pot off the heat and stir in the Greek yogurt and the lemon juice, if using. Rest 2 minutes, taste once more for salt, and serve with extra parmesan over the top.
