Step‑by‑Step Instructions for Campbells Green Bean Casserole
Step 1: Prepare Green Beans
Begin by prepping your green beans for the Campbells Green Bean Casserole. If using fresh beans, trim the ends and blanch them briefly in a pot of salted boiling water for about 3-4 minutes until just tender. Drain well and set aside. If opting for frozen beans, simply thaw and drain any excess liquid, while canned beans require just draining.
Step 2: Preheat Oven
Preheat your oven to 350°F (175°C). This step is essential to ensure that your casserole bakes evenly and emerges bubbly and delicious. While the oven heats, gather your baking dish and other ingredients, preparing for a smooth assembly.
Step 3: Mix Sauce
In a mixing bowl, whisk together 1 can of condensed cream of mushroom soup, ½ cup of milk, and 1 teaspoon of soy sauce until completely smooth. The mixture should be creamy and free of lumps. This sauce forms the rich foundation of the Campbells Green Bean Casserole, adding depth and creaminess once baked.
Step 4: Combine Ingredients
Gently fold in the prepared green beans, along with ⅔ cup of crispy fried onions and ¼ teaspoon of ground black pepper into the sauce mixture. Stir until all the beans are evenly coated with the creamy sauce. The contrast of textures, from beans to onions, will create a delightful experience in your casserole.
Step 5: Bake First Layer
Pour the assembled mixture into a greased 9×9-inch baking dish, spreading it out evenly. Place the dish in the preheated oven and bake for 25 minutes, or until the edges are bubbling and the top is slightly set. This initial baking allows the flavors to meld beautifully before the finishing touches.
Step 6: Add Topping
Once the casserole is bubbling, carefully remove it from the oven. Give the mixture a gentle stir and sprinkle the reserved ⅓ cup of crispy fried onions evenly over the top. Return the dish to the oven and bake for an additional 5 minutes, or until the onions are golden brown and beautifully crunchy on top.
Step 7: Serve and Enjoy
Once the Campbells Green Bean Casserole is done baking, remove it from the oven and let it sit for a few minutes before serving. This brief cooling period allows the flavors to settle beautifully and makes it easier to serve. Dish out spoonfuls of this creamy comfort food and enjoy with family and friends!

Make Ahead Options
This Classic Campbell’s Green Bean Casserole is ideal for busy home cooks looking to save time during hectic weeks or festive gatherings! You can prepare the green beans by blanching (if using fresh) or simply thawing (if using frozen) up to 24 hours in advance. Additionally, mix the creamy sauce ingredients together and store them in the refrigerator for up to 3 days; just keep the fried onions separate to maintain their crunch. When you’re ready to bake, combine the beans and sauce in your baking dish, bake as directed for 25 minutes, then top with fried onions and return to the oven for the final 5 minutes. This way, you’ll have a delicious, hassle-free dish ready to enjoy!
How to Store and Freeze Campbells Green Bean Casserole
- Fridge: Store leftovers in an airtight container for up to 4 days. The flavors actually deepen after a day, making it even more delicious!
- Freezer: For longer storage, freeze the casserole (without the topping) in a freezer-safe container for up to 3 months. Be sure to label it!
- Thawing: To enjoy, thaw in the fridge overnight and reheat in the oven at 350°F until bubbly, or microwave it until warmed through.
- Reheating: If reheating in the oven, consider adding fresh crispy fried onions on top during the last few minutes for that perfect crunch.
