Ingredients
Method
- Heat a large skillet over medium heat, then add chopped walnuts. Cook until fragrant, about 1-2 minutes, stirring often so they don't burn. Transfer to a bowl and set aside. Add 2 Tbsp olive oil to the skillet, then add anchovies. Use a wooden spoon or spatula to carefully press into and break apart the filets. Be careful, oil may splatter. Cook until the anchovies are melted and broken down, then pour into a mixing bowl.
- Make the vinaigrette. To the bowl with the anchovy oil, add chopped herbs, vinegar, capers, Dijon, whole grain mustard, and sugar. Whisk to combine, then set aside.
- Cook the French green beans. Add remaining 2 Tbsp olive oil to the skillet, then heat over medium-high heat. When hot, add trimmed green beans and cook, stirring often, until blistered (not burnt!), about 5-7 minutes. Green beans should still have a slight crunch to them. Season with kosher salt.
- Add the vinaigrette. Pour the anchovy vinaigrette into the skillet along with the sliced scallions, then toss to combine. Transfer cooked green beans to a large serving bowl. Top with toasted walnuts, then serve immediately or at room temperature.
