Green Bean Casserole: Classic Holiday Side Dish Recipe
I’ve loved Green Bean Casserole since my grandmother first served it at Thanksgiving — the warm, creamy mix of green beans, mushrooms, and crunchy fried onions felt like a hug on a plate. Growing up, it was always the dish that disappeared first from the buffet, and making it now brings back the comfort of that kitchen and family conversations. The casserole itself has a bit of Americana history: popularized in the 1950s as an easy, pantry-friendly holiday staple, it remains a nostalgic favorite at many tables today.

FAQ
Q: Can I freeze this recipe?
A: Yes — assemble the casserole up to step 7, cover tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking, then bake as directed (you may need to add a few extra minutes).
Q: What can I use instead of sour cream?
A: You can substitute plain Greek yogurt for a tangy, protein-rich alternative, or use mayonnaise for extra richness. Both work well to maintain creamy texture.
Q: Can I make this vegetarian?
A: Yes — omit the bacon and use a vegetarian cream-of-mushroom soup or a homemade béchamel. Consider adding toasted nuts (like pecans) or sautéed tempeh for texture.
Q: How can I make the green beans more tender if I prefer them softer?
A: Blanch them a minute or two longer (up to 6–7 minutes total), then proceed with the recipe. You can also steam the beans until they reach your preferred tenderness.
Tips & Tricks
- Don’t over-blanch: aim for tender-crisp beans so they won’t turn mushy after baking.
- Reserve a little bacon fat to sauté the mushrooms — it adds depth of flavor.
- If you like extra crunch, stir half of the French fried onions into the casserole before baking and save the rest for topping after baking.
- Taste before baking: adjust salt and pepper after combining the ingredients to ensure balanced flavor.
