To make this recipe vegetarian, feel free to leave out the anchovy. A handful of toasted walnuts with a sprinkling of fennel pollen (if you have it as it’s very hard to find) is a wonderful way to push this spaghetti dish with swiss char all the way.
Set a stockpot over a high heat and bring to a boil. Once the water is boiling, salt it generously and poor in the spaghetti. Cook until al dente. Drain.
Once the pasta water is on, set a large pan over a medium heat and add a splash of olive oil. When it’s shimmering, add the garlic and anchovy paste and cook just until the garlic is soft. Add the Swiss chard stems and cook until softened. Add the Swiss chard leaves one handful at a time, stirring and flipping with tongs until the leaves are wilted.
When the pasta is ready and the chard is wilted, add the spaghetti, lemon zest, Parmesan cheese, and crème fraîche to the pan. Turn off the heat and mix the pasta well. Add a bit of pepper to taste and serve.
