Step-by-Step: How to Make Campbell Soup Green Bean Casserole Recipe
Preparing the Green Beans
If you’re using fresh green beans, start by trimming the ends and washing them thoroughly. To achieve the ideal tender-crisp texture, blanch the beans in boiling water for about 4-5 minutes, then immediately transfer them to an ice bath. This stops the cooking process and helps preserve that vibrant green color you want.
For canned green beans, simply drain and rinse them to remove excess sodium and any canning liquid that might affect the flavor.
Mixing the Creamy Base
In a large mixing bowl, combine your Campbell’s cream of mushroom soup with the milk. This mixture will create the rich, velvety sauce that binds your casserole together. Add freshly ground black pepper and salt if needed, then stir until the consistency is smooth.
Assembling Your Casserole
Next, gently fold your prepared green beans into the soup mixture. You want every bean to be coated but not drowning in sauce. Transfer the mixture to a greased baking dish—about 1.5-quart size works well.
Baking to Perfection
Preheat your oven to 350°F (175°C). Place the casserole in the oven and bake uncovered for 25 minutes. After that, sprinkle the French fried onions evenly on top. Return the dish to the oven for another 5-10 minutes, or until the onions turn golden brown and crispy.
Keep a close eye to avoid burning the topping; you want it to add crunch and flavor without bitterness.
Tips to Elevate Your Campbell Soup Green Bean Casserole Recipe
If you want to take your casserole to the next level, consider these handy tips:
- Boost the Flavor: Add a teaspoon of garlic powder or freshly minced garlic to the soup mixture for an extra punch.
- Add Cheese: A sprinkle of shredded cheddar or Parmesan cheese just before baking gives your casserole a rich, savory twist.
- Fresh Mushrooms: Sauté a cup of fresh mushrooms and fold them into the mix for an earthy flavor upgrade.
- Keep It Crispy: Wait until the last 5-10 minutes to add the fried onions to avoid sogginess.
- Herbs: Fresh thyme or rosemary pairs beautifully and brings a fragrant note to the dish.
How to Store and Reheat Leftover Casserole
If you’re lucky enough to have leftovers (or want to prep ahead), here’s how to keep your casserole tasting fresh:
- Store in an airtight container in the refrigerator for up to 3 days.
- To reheat, cover with foil and warm in a 350°F oven for about 15-20 minutes.
- For best results, add fresh fried onions on top after reheating to regain that crispy texture.
