This green bean casserole is a classic side dish that combines creamy mushroom soup and crispy fried onions for a comforting, quick to make recipe that works on busy weeknights or holiday tables.
I first made this casserole on a whim when I wanted a wholesome side without extra fuss, and it quickly became a favorite for family dinners especially around the holidays.
Ingredients
- Condensed cream of mushroom soup: brings creamy umami richness. Choose a smooth, fresh can for the best flavor.
- Milk: adds a silky texture and balances out the soup. Whole milk works well but any kind will do.
- Soy sauce: enhances depth and gives a subtle savory note that makes the casserole more complex. Look for a naturally brewed soy sauce.
- Green beans: are the green star here. Fresh green beans should be tender and vibrant. If using canned, drain well to avoid sogginess. Frozen green beans are a convenient alternative that still tastes great.
- Crispy French fried onions: add a crunchy, golden top that is iconic to this dish. Use a brand that stays crisp after baking.
- Freshly ground pepper: to season and balance the creaminess. Use just enough to brighten the flavors.
Instructions
- Build The Bean Base:
- If using fresh green beans clean and cut them into even pieces. Blanch them in boiling water for 2 minutes to keep them tender crisp and bright. For canned beans drain thoroughly to avoid water diluting the sauce. Frozen green beans can be used straight from thawed state.
- Mix The Sauce:
- In a bowl combine the condensed mushroom soup and milk. Stir vigorously to remove any lumps until silky smooth. Add soy sauce and mix well to incorporate that earthy savory boost.
- Combine And Season:
- Fold in the green beans with two thirds of the crispy fried onions to distribute crunch throughout. Sprinkle in pepper according to your taste. This combination marries creamy elements with textures and seasoning.
- Assemble The Casserole:
- Spray a 9 by 9 inch casserole dish lightly with cooking spray to prevent sticking. Transfer the green bean mixture evenly into the dish and smooth the top.
- Cook And Crisp:
- For air fryer cooking preheat to 350 degrees Fahrenheit. Bake casserole for 10 minutes then stir gently. Sprinkle the remaining onions over the surface and cook for 2 more minutes to brown the topping nicely. For oven baking preheat to 350 degrees Fahrenheit. Bake casserole for 25 minutes until heated through and bubbly. Stir, then add remaining onions on top and bake for 5 more minutes until golden and crisp.
My favorite ingredient to highlight is always the crispy French fried onions because they bring the casserole to life with their crunchy contrast. Making this dish reminds me of family holidays when this casserole would always appear on the table stirring warm memories alongside the feast.
Storage tips
Store leftovers in an airtight container in the refrigerator and consume within 3 to 4 days for best taste and texture. Reheat gently in the oven or microwave until warmed through. If the topping loses its crispness after reheating, sprinkle a few extra fried onions on top before serving for fresh crunch.
Ingredient swaps
Try cream of celery or cream of chicken soup instead of mushroom for a different flavor profile that still offers creaminess. Use coconut or oat milk to keep the dish dairy free without sacrificing texture. Substitute shallots or diced onions lightly sautéed for fried onions inside the casserole for a fresher onion flavor if you prefer.
Serving ideas
This casserole pairs perfectly with herb roasted chicken or turkey and mashed potatoes for a classic comfort meal. Add a simple leafy green salad with lemon vinaigrette to brighten the plate and balance the richness. Serve alongside roasted root vegetables to add a hearty vegetable variety.
This green bean casserole brings nostalgia and ease together in one dish perfect for any occasion.
