About This Recipe
For many families, Thanksgiving would not be complete without green bean casserole. This from-scratch version keeps everything we love about the classic — creamy, savory and topped with crunchy onions — but replaces the canned soup with a simple homemade mushroom sauce that tastes fresher and richer.
You can assemble it a day ahead, which frees up precious time on the holiday itself.
Tips for Success
- Blanching the beans keeps them bright green and crisp-tender.
- To make ahead, assemble without the onion topping, cover and refrigerate up to 24 hours. Add 10 minutes to the baking time.
- Frozen green beans work in a pinch — thaw and pat dry first.
Classic Green Bean Casserole from Scratch
Tender green beans in a creamy homemade mushroom sauce, topped with crispy onions — the holiday favorite, made from scratch.
Ingredients
Instructions
- Heat the oven to 375°F. Butter a 2-quart baking dish.
- Bring a large pot of salted water to a boil. Cook the green beans for 5 minutes, then drain and plunge into ice water. Drain well.
- Melt the butter in a large skillet over medium heat. Cook the mushrooms and onion for 8 to 10 minutes, until the mushrooms are browned. Add the garlic for 1 minute.
- Sprinkle in the flour and stir for 1 minute. Slowly whisk in the broth and milk and simmer until thickened, 3 to 4 minutes. Season with salt, pepper and nutmeg.
- Stir in the green beans and ½ cup of the fried onions. Transfer to the baking dish.
- Bake for 20 minutes. Top with the remaining fried onions and bake 5 to 10 minutes more, until golden and bubbling.

Questions & Answers
Can I use canned green beans?
Fresh or frozen beans give the best texture, but well-drained canned beans can be used; skip the blanching step.
How do I keep the topping crisp?
Add most of the fried onions only during the last 5 to 10 minutes of baking.
