How to Make Green Bean Casserole

1. Preheat the oven to 350 degrees Fahrenheit and lightly grease your casserole dish.
2. If using fresh green beans, blanch them in boiling water for about 5 minutes, then drain. Frozen green beans can be used straight from the freezer.
3. In a mixing bowl, combine the cream of mushroom soup, milk, garlic powder, onion powder, and half of the fried onions. Add salt and pepper to taste.
4. Stir in the green beans and shredded cheese until everything is evenly coated.
5. Transfer the mixture to your casserole dish and smooth the top.
6. Bake for 25 minutes, then sprinkle the remaining fried onions over the top.
7. Bake for an additional 5 minutes or until the onions are golden and the casserole is bubbling around the edges.
8. Let it rest for a few minutes before serving.

Tips for Making the Best Green Bean Casserole

Keep the sauce smooth by whisking your soup and milk thoroughly before adding the green beans. If you prefer a richer texture, swap the milk for half-and-half. Always add the fried onions on top near the end of baking so they stay crunchy instead of soggy. And if you’re serving a crowd, double the recipe and bake it in a larger dish.

Common Mistakes to Avoid

Many home cooks make the mistake of overcooking the green beans before baking, which leads to a mushy casserole. Blanching or thawing is enough. Another common issue is forgetting to season the sauce. Creamy casseroles need a good pinch of salt and pepper. Finally, baking the fried onions for the full duration can cause them to burn, so always add them near the end.

Variations and Substitutions

For a more decadent version, use heavy cream instead of milk. If you prefer a lighter option, use low-sodium cream soup or substitute it with a homemade mushroom sauce. You can also add protein like diced cooked bacon or shredded rotisserie chicken. For a flavor twist, swap cheddar for Swiss or Gruyere cheese. And if you want a gluten-free version, choose gluten-free fried onions and soup.

How to Store and Meal Prep

Green bean casserole stores surprisingly well. Keep leftovers in an airtight container for up to 4 days. To reheat, bake at 350 degrees until warm or microwave individual portions. If you’re prepping ahead, assemble the casserole the day before but wait to add the fried onion topping until just before baking. You can also freeze the unbaked casserole for up to 2 months.

Serving and Presentation Ideas

Serve this casserole right in the baking dish for a cozy, rustic look, or scoop it into a white serving bowl that makes the green beans stand out. Pair it with roasted turkey, baked chicken, meatloaf, mashed potatoes, or any hearty main. A sprinkle of fresh parsley on top adds a simple touch of color that makes it feel special.
