Campbell’s Green Bean Casserole Recipe | Classic Easy Holiday Side Dish
There are certain side dishes that instantly bring the feeling of a holiday gathering to the table, and Campbells Green Bean Casserole is one of them. Creamy green beans covered with a savory mushroom sauce and finished with crispy fried onions create a simple combination that has become a familiar favorite for family dinners and special occasions.
INGREDIENTS YOU’LL NEED FOR CAMPBELLS GREEN BEAN CASSEROLE
The ingredient list for Campbells Green Bean Casserole is short, but every ingredient contributes something important to the finished dish.
CAMPBELLS GREEN BEAN CASSEROLE INGREDIENTS
- 1 can condensed cream of mushroom soup, 10.5 ounces
- 1/2 cup milk
- 1 teaspoon soy sauce
- 4 cups cut green beans
- 1 1/3 cups crispy French fried onions, divided
- 1/4 teaspoon black pepper, or to taste
- Cooking spray for the casserole dish
The cream of mushroom soup creates the creamy base of the casserole. Mixing it with milk makes the sauce smoother and easier to coat the green beans.
Soy sauce adds a small amount of savory depth. Although only one teaspoon is used, it helps balance the creamy mushroom flavor.
For the green beans, the reference recipe allows canned, frozen, or fresh beans. Four cups are equivalent to approximately two cans of green beans. If using fresh green beans, they should be blanched briefly before being added to the casserole.
The French fried onions are divided between the casserole mixture and the topping. Some are mixed into the green beans for flavor, while the remaining onions are added near the end of cooking to create the crisp golden topping.
Because the soup and soy sauce already contain salt, additional salt is generally unnecessary. A little black pepper is enough to season the dish.
HOW TO MAKE CAMPBELLS GREEN BEAN CASSEROLE
Start by preheating your oven to 350°F. Lightly coat a 9×9-inch casserole dish with cooking spray and set it aside.
If you are using canned green beans, drain them thoroughly in a colander. Removing excess liquid helps prevent the casserole from becoming watery.
If you are using fresh green beans, wash them and trim the ends. Bring a large pot of water to a boil and blanch the beans for about two minutes. Drain them well before continuing.
Frozen green beans can be used without thawing according to the reference recipe.
Next, prepare the creamy mushroom sauce. Add the condensed cream of mushroom soup and milk to a large mixing bowl. Stir until the mixture becomes smooth and the soup is evenly blended with the milk.
Add the teaspoon of soy sauce and stir again. The sauce should be creamy and evenly seasoned.
Add the prepared green beans to the bowl. Then add approximately 2/3 cup of the crispy French fried onions, reserving the remaining onions for the topping.
Season with black pepper and gently stir everything together. Make sure the green beans are evenly coated with the creamy mushroom mixture.
Pour the mixture into the prepared casserole dish. Spread it into an even layer so that it cooks consistently.
CAMPBELLS GREEN BEAN CASSEROLE OVEN AND AIR FRYER METHODS
For the oven method, place the casserole in the preheated 350°F oven and bake for approximately 25 minutes. The center should be hot and the sauce should be bubbling gently around the edges.
Remove the dish from the oven and carefully stir the casserole. This helps distribute the heat throughout the center.
Spread the remaining crispy French fried onions evenly over the top. Return the casserole to the oven and bake for approximately 5 additional minutes, until the onions are golden brown and crisp.
If your oven is already crowded with other dishes, the casserole may need additional cooking time. Check the center before serving to make sure it is thoroughly hot.
For the air fryer method, use a small baking dish that fits comfortably inside your air fryer. Lightly coat the dish with cooking spray and add the green bean mixture.
Cook at 350°F for approximately 10 minutes. Carefully remove the dish and stir the casserole so the center heats evenly.
Smooth the surface and add the remaining fried onions. Return the dish to the air fryer and cook for another 2–3 minutes, just until the onions become golden and crispy.
Take care when removing the hot dish from the air fryer. Use appropriate oven mitts or a heat-resistant utensil to protect your hands.
The air fryer method is particularly useful when your oven is occupied with other holiday dishes.
FLAVOR, TEXTURE, AND CAMPBELLS GREEN BEAN CASSEROLE TIPS
The appeal of Campbells Green Bean Casserole comes from the contrast between its creamy interior and crispy topping.
The mushroom sauce is smooth, rich, and savory. The green beans provide a mild vegetable flavor and a tender texture, while the soy sauce adds a subtle umami note.
The fried onions are what give the casserole its most recognizable character. Some onions soften slightly inside the creamy mixture, while the onions placed on top remain crisp and golden.
For the best texture, avoid adding the final onions too early. Keeping them separate until the last few minutes of cooking allows them to maintain their crunch.
If you prefer fresh green beans, blanching them for about two minutes before assembling the casserole keeps them tender while allowing them to retain some texture.
You can also prepare Campbells Green Bean Casserole in advance. Assemble the green bean mixture and place it in the refrigerator until you are ready to cook. Keep it covered and refrigerated.
Because the casserole will be cold when it goes into the oven, it will require additional cooking time. The reference recipe recommends approximately 35 minutes in the oven when starting from the refrigerator, followed by the final topping step.
For the air fryer, a refrigerated casserole may need approximately 15 minutes before adding the final onions.
There are also several easy ways to customize the dish. Cooked crumbled bacon can be added for extra savory flavor. Cheese can be mixed into the green beans and sprinkled over the top. You can also replace the cream of mushroom soup with another condensed soup, such as cream of celery or cream of asparagus.
For a different crunchy topping, sliced or chopped almonds can be used instead of fried onions.
SERVING AND STORING CAMPBELLS GREEN BEAN CASSEROLE
Campbells Green Bean Casserole is best served warm, shortly after the crispy onions have browned.
Place the casserole in the center of the dinner table and serve it alongside roasted turkey, chicken, mashed potatoes, stuffing, or other traditional side dishes.
For a holiday presentation, you can garnish the top with a small amount of fresh parsley. The green color adds a simple contrast to the creamy casserole and golden onions.
If you are preparing the casserole ahead, keep the fried onion topping separate until the final stage of cooking. This helps preserve its crisp texture.
The casserole can also be frozen. For the best result, freeze it without the crispy onion topping because the onions will lose their crunch during freezing and reheating.
If freezing, place the casserole in an airtight freezer-safe container and freeze for up to three months. Thaw it overnight in the refrigerator before reheating.
Bake the thawed casserole covered at 350°F for about 20 minutes, then uncover and continue baking for approximately 10 minutes, or until the center is hot. Add fresh crispy onions on top and bake for another five minutes to brown them.
