Ingredients

Scale
  • 4 medium shallots (halved lengthwise & then sliced thinly into half moons)
  • 1 cup vegetable oil
  • Creole Cajun Seasoning – homemade or store-bought (or seasoned salt), to taste
  • 24 ounces fresh green beans (ends trimmed)
  • 4 tablespoons unsalted butter
  • 8 ounces baby bella mushrooms (sliced)
  • 1 tablespoon garlic (minced or paste)
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups chicken broth
  • 1 tablespoon fresh lemon juice
  • 2 teaspoons Dijon mustard (smooth or whole grain)
  • 1 teaspoon dried thyme
  • 1/4 teaspoon ground nutmeg
  • kosher salt & freshly ground black pepper (to taste)
  • 1/2 cup heavy whipping cream (or half and half)
  • 1/2 cup freshly grated parmesan cheese (divided)

Instructions

  1. Step 1: Prepare the fried shallots: Heat vegetable oil in a skillet over medium heat. Add sliced shallots and fry until golden brown and crispy (about 5–7 minutes).
  2. Step 2: Cook the green beans: Blanch trimmed green beans in salted boiling water for 5 minutes until tender-crisp; drain.
  3. Step 3: Make the creamy mushroom sauce: In a pan, melt butter and sauté mushrooms and garlic until browned (5–6 minutes). Stir in flour to form a roux. Gradually whisk in chicken broth, adding lemon juice, Dijon mustard, thyme, salt, pepper, and cream until thickened.
  4. Step 4: Assemble the casserole: Combine blanched green beans with mushroom sauce in a baking dish. Top with half of the parmesan cheese and fried shallots; sprinkle remaining cheese on top.
  5. Step 5: Bake: Preheat oven to 350°F (175°C) and bake for 25 minutes until bubbly and golden.
