I like to make my own savory cream sauce for the timeless green bean casserole. This time I added another vegetable for a delicious twist that sets my casserole apart from the rest! You can omit the vermouth if you'd like by substituting another half-cup of chicken broth. —Ann Sheehy, Lawrence, Massachusetts

To make a day ahead: Assemble the casserole and let cool to room temperature, then cover with foil and refrigerate. Bake, covered, for about 45 minutes, uncover and bake until bubbly, about 10 more minutes.

Directions

  1. 1
    Preheat oven to 375°. In a Dutch oven, bring 12 cups water to a boil. Add cauliflower and beans; cook, uncovered, just until beans turn bright green, 1-2 minutes. Drain and immediately drop into ice water. Drain and pat dry.
  2. 2
    In a large skillet, heat 1 teaspoon oil over medium-high heat. Add bread crumbs; cook and stir until lightly browned, 2-3 minutes. Stir in french-fried onions. Remove crumbs and onions and reserve.
  3. 3
    In the same skillet, heat butter and remaining 3 teaspoons oil over medium heat. Add mushrooms and shallot; cook and stir until tender, 8-10 minutes. Add garlic; cook 1 minute longer. Stir in flour until blended. Gradually whisk in vermouth; cook, stirring until most of the liquid is gone. Whisk in broth and seasonings. Stirring constantly, bring to a boil; cook and stir until thickened, 6-8 minutes. Remove from heat; stir in ham, sour cream, yogurt and reserved vegetables. Transfer to a greased 13x9-in. baking dish.
  4. 4
    Bake, uncovered, until bubbly, 30-40 minutes. Sprinkle with bread crumb mixture before serving.
