Step-by-Step Green Bean Casserole Campbell’s Recipe

Step 1: Prepare the Green Beans
You can use fresh green beans or canned green beans:
- Fresh green beans: Trim the ends and blanch in boiling salted water for about 3-4 minutes until bright green and just tender. Drain and rinse with cold water to stop cooking.
- Canned green beans: Drain well to avoid a watery casserole.
Step 2: Mix the Sauce
In a large mixing bowl, combine Campbell’s Cream of Mushroom Soup, milk, soy sauce (if using), black pepper, and a pinch of salt. Whisk until smooth and creamy.
Step 3: Combine Green Beans and Sauce
Add the green beans to the sauce mixture and gently stir to coat evenly.
Step 4: Assemble the Casserole
Transfer the green bean and sauce mixture to a greased 9×13-inch baking dish. Spread it out evenly.
Step 5: Add Fried Onions
Sprinkle half of the crispy fried onions over the green bean mixture.
Step 6: Bake
Preheat your oven to 350°F (175°C). Bake the casserole uncovered for 25 minutes.
Step 7: Add Remaining Onions
Remove from the oven, sprinkle the remaining fried onions on top, and bake for an additional 5-10 minutes until the onions are golden brown and crispy.
Step 8: Serve Warm
Let the casserole cool for a few minutes before serving. Enjoy this creamy, crunchy classic with your favorite holiday meal or as a comforting side dish anytime!
