Green bean casserole from scratch keeps the nostalgic creamy-and-crispy contrast while replacing canned soup with a quick mushroom sauce. Fresh beans stay brighter and firmer, which gives the finished dish more texture.
Blanching the beans first and reducing the sauce until it coats a spoon prevents a watery casserole. The crispy onions go on near the end so they stay crunchy instead of disappearing into the sauce.

ShiMuv Holiday Recipe
Ingredients
- 1½ pounds fresh green beans, trimmed and halved
- 12 ounces cremini mushrooms, sliced
- 4 tablespoons unsalted butter
- 1 small yellow onion, finely diced
- 2 garlic cloves, minced
- ¼ cup all-purpose flour
- 1½ cups low-sodium chicken or vegetable broth
- 1 cup half-and-half
- 1 teaspoon fresh thyme leaves
- 1 tablespoon soy sauce or Worcestershire sauce
- ¾ teaspoon kosher salt
- ½ teaspoon black pepper
- 1½ cups crispy fried onions, divided
How to Make It
- Heat the oven to 375°F and lightly butter a 9×13-inch baking dish. Bring a large pot of salted water to a boil and set a colander nearby.
- Boil the green beans 4 minutes, just until bright green and crisp-tender. Drain immediately and rinse briefly under cold water to stop the cooking, then let them dry well.
- Melt butter in a large skillet over medium-high heat. Add mushrooms and cook 6–8 minutes until their released moisture evaporates and the edges begin to brown.
- Reduce heat to medium. Add diced onion and cook 4 minutes, then add garlic for 30 seconds. Sprinkle flour over the vegetables and stir for 1 minute so the raw flour taste cooks out.
- Gradually whisk in broth, then half-and-half. Add thyme, soy sauce, salt, and pepper. Simmer 4–6 minutes until the sauce is thick enough to coat the back of a spoon.
- Fold the dried green beans and ½ cup crispy onions into the mushroom sauce. Transfer to the baking dish and spread evenly.
- Bake uncovered 18–20 minutes until the sauce is bubbling around the edges. Sprinkle the remaining crispy onions over the top and bake 7–10 minutes more until they are golden.
- Rest 5–10 minutes before serving. The sauce will thicken slightly as it cools, and the beans should remain tender with a little bite.
Recipe tip: Dry the blanched green beans well before adding them to the sauce; surface water can thin the casserole.
Food safety: Keep dairy-based casserole refrigerated until baking, and refrigerate leftovers within 2 hours. Reheat leftovers until steaming hot throughout.
