Serving Suggestions
Serve this greenbean casserole recipe alongside your turkey and cranberry stuffing balls, or add it to your Thanksgiving sides lineup. Pair it with mashed potatoes, roasted sweet potatoes, or a fresh cucumber carrot salad for a complete meal.
Storage & Reheating
If you have leftovers, let the casserole cool completely before refrigerating. To reheat, bake at 350°F for 15 minutes until warm and bubbly. Avoid microwaving for too long, as it can make the onions soggy. You can also freeze greens like green beans separately to save time for your next casserole.
FAQs
Can I make Campbells Green Bean Casserole ahead of time?
Yes! Prepare it up to one day in advance, cover, and refrigerate. Add the topping and bake just before serving.
Can I use canned green beans?
Absolutely. Just drain them well before mixing. Canned beans are softer, while frozen green beans keep a bit more bite.
Can I double the recipe?
Definitely! Just use a larger 3-quart baking dish and double all ingredients.
