Instructions

  1. Step 1: Trim green beans and blanch in boiling salted water for 4 minutes until bright green; drain and set aside.
  2. Step 2: Melt butter in a saucepan over medium heat. Whisk in flour and cook for 2 minutes until bubbly.
  3. Step 3: Gradually whisk in milk, stirring constantly, until sauce thickens and coats the back of a spoon (about 8-10 minutes).
  4. Step 4: Remove from heat; stir in salt, pepper, and half the parsley. Add green beans and toss to coat.
  5. Step 5: Transfer to a greased baking dish. Thinly slice shallots and fry in 1 tbsp oil until golden and crisp (about 2 minutes per side), then drain on paper towels.
  6. Step 6: Sprinkle fried shallots and remaining parsley over casserole before serving.
