Step‑by‑Step Instructions for Classic Campbell’s Green Bean Casserole
Step 1: Prep Green Beans
Begin by preparing your green beans for the Classic Campbell’s Green Bean Casserole. If using fresh green beans, trim the ends and blanch them in boiling water for just 3-4 minutes until they are crisp-tender. For canned green beans, simply drain and pat them dry with a paper towel. Set your prepped beans aside, ready to absorb those delightful flavors.
Step 2: Preheat Oven
While you prepare the green beans, preheat your oven to 350°F (or use an air fryer if preferred). This will ensure that the casserole cooks evenly and comes out perfectly bubbly and golden. The warm oven will help create that irresistibly creamy texture that makes the Campbell’s Green Bean Casserole a family favorite.
Step 3: Mix Sauce
In a large mixing bowl, whisk together the condensed cream of mushroom soup, milk, soy sauce, and ground black pepper until smooth and well-combined. This creamy mixture serves as the heart of your casserole. It should be velvety and rich, with a hint of seasoning from the soy sauce to elevate the flavor profile of the Classic Campbell’s Green Bean Casserole.
Step 4: Combine Ingredients
Gently fold the prepared green beans and 2/3 cup of crispy fried onions into the creamy sauce from step 3. Ensure that each green bean is well coated in this delicious mixture. The wonderful combination of flavors and textures will create a satisfying base for your casserole. Once everything is combined, you’re ready to bake!
Step 5: Bake Casserole
Pour the green bean mixture into a greased 9×9-inch baking dish and spread it out evenly. Place the dish in the preheated oven and bake for 25 minutes. You’ll know it’s ready when the edges are bubbling, and the center is hot. This is when the magic happens, transforming all those delicious elements into a comforting casserole.
Step 6: Add Topping & Finish Baking
After 25 minutes, carefully remove the casserole from the oven and stir it gently. Sprinkle the reserved crispy fried onions on top for that signature crunch. Return the dish to the oven and bake for an additional 5 minutes until the onions are golden and crispy. This final touch will add the perfect texture and flavor to your Classic Campbell’s Green Bean Casserole.

Make Ahead Options
These Classic Campbell’s Green Bean Casserole are perfect for meal prep enthusiasts! You can prepare the green bean mixture (without the fried onions) and refrigerate it for up to 24 hours in advance, maintaining its rich, creamy flavor. Simply mix the cream of mushroom soup, milk, soy sauce, and pepper, then fold in the green beans, and store it in an airtight container. To keep the casserole fresh, layer a piece of plastic wrap against the surface before sealing the container. When you’re ready to bake, just pour the mixture into your baking dish, top with reserved crispy fried onions, and bake for about 30 minutes (25 minutes initially, then 5 minutes with the topping) at 350°F. This way, you’ll enjoy comforting deliciousness with minimal effort on the day of serving!

Campbells Green Bean Casserole Recipe FAQs
How do I choose the best green beans?
Absolutely! When selecting green beans, look for vibrant, firm pods that snap easily when bent. If using fresh, opt for bright green beans without dark spots or blemishes. Canned green beans should be rinsed and drained well to remove excess sodium and prevent the casserole from becoming soggy.
What’s the best way to store leftovers?
For storing leftovers, transfer the cooled casserole into an airtight container. It will stay fresh in the refrigerator for up to 4 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F until heated through and bubbly—just like fresh!
Can I freeze Campbell’s Green Bean Casserole?
Yes, you can! To freeze, prepare the casserole but do not add the crispy fried onions. Cover the dish tightly with plastic wrap and then aluminum foil for added protection against freezer burn. It can last up to 3 months in the freezer. When you’re ready to bake, thaw it in the refrigerator overnight and then add the onions just before baking for that delightful crunch.
How can I avoid a watery casserole?
To prevent a watery casserole, it’s essential to drain canned beans thoroughly. If using fresh beans, make sure to blanch them for only 3-4 minutes until crisp-tender, as overcooking can release too much moisture. Additionally, patting canned beans dry with a paper towel helps absorb any excess liquid, keeping your casserole creamy and delicious.
Is this casserole suitable for special dietary needs?
Very! If you’re adapting for dietary restrictions, you can use low-fat versions of the cream of mushroom soup and milk without sacrificing flavor. For those avoiding gluten, check for gluten-free crispy onion toppings. Always read labels to ensure they meet your specific dietary needs, especially if allergies are a concern.
How can I make this casserole ahead of time?
Certainly! You can prep the casserole filling ahead of time by mixing the green beans with the sauce but holding off on baking and adding the fried onions. Store it in the refrigerator for up to 24 hours. When you’re ready to serve, pour the mixture into your baking dish, top with onions, and bake as per the recipe instructions. This way, you can enjoy a homemade meal even on the busiest days!
