Ingredients
  

  • Fresh green beans (1½ pounds), trimmed and halved; frozen cut green beans (24 ounces) work too
  • Cream of mushroom soup (2 cans, 10.5 ounces each)
  • Whole milk (¾ cup) or half-and-half for richer sauce
  • Fried crispy onions (2 cups), divided
  • Garlic (2 cloves), minced
  • Soy sauce (1 teaspoon) or Worcestershire sauce (1½ teaspoons)
  • Black pepper (½ teaspoon) and kosher salt (to taste)
  • Optional flavor boosters: grated Parmesan (¼ cup), pinch of nutmeg, or a squeeze of lemon
  • Butter (1 tablespoon) for sautéing garlic, optional
  • Cooking spray or a little oil for the baking dish

Method
 

  1. Heat the oven. Preheat to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
  2. Prep the beans. Bring a large pot of salted water to a boil. Add green beans and cook 3–4 minutes until crisp-tender and bright. Drain and rinse under cold water to stop the cooking. Pat dry.
  3. Sauté the garlic (optional but recommended). In a small skillet over medium heat, melt butter and cook garlic 30–60 seconds until fragrant. Don’t brown it.
  4. Make the sauce base. In a large bowl, whisk together cream of mushroom soup, milk, soy or Worcestershire, black pepper, and a small pinch of salt. Stir in the sautéed garlic. If using Parmesan or a pinch of nutmeg, add now.
  5. Combine. Fold the blanched green beans and 1 cup of crispy onions into the sauce until evenly coated.
  6. Assemble. Spread the mixture in the prepared baking dish. Smooth the top.
  7. Bake, uncovered, for 20 minutes. The edges should bubble and the center should be hot.
  8. Add the crunchy topping. Sprinkle the remaining 1 cup crispy onions over the top. Bake another 8–10 minutes until golden and crisp.
  9. Finish and serve. Let it rest 5–10 minutes to set. For a bright finish, add a light squeeze of lemon over the top before serving.
