Detailed Step-by-Step Instructions

Bean preparation:
If using fresh, blanch just until bright green. Drain canned beans thoroughly in colander. Pat beans dry to prevent watery sauce. Keep frozen beans frozen until mixing. Cut any very long beans in half.
Perfect sauce creation:
Whisk soup and milk until completely smooth. Add soy sauce gradually. Season with fresh pepper. Check thickness - should coat back of spoon. Adjust seasonings to taste.
Mixing technique:
Fold beans gently into sauce. Add first portion of onions. Mix just until evenly coated. Avoid breaking or mashing beans. Transfer carefully to baking dish.
Baking process:
Use preheated oven. Check at 20 minutes. Stir gently to distribute heat. Add topping onions evenly. Watch carefully for proper browning.

My holiday cooking experience has taught me that while this recipe is simple, attention to detail makes the difference between good and great. The moment you achieve that perfect golden-brown crust of crispy onions is pure holiday magic.

Temperature Management

Understanding heat is crucial:

  • Preheat oven thoroughly before starting
  • Keep at consistent 350°F throughout
  • Check center temperature before adding onions
  • Watch final browning carefully

Make-Ahead Tips

Perfect for busy holiday prep:

  • Assemble up to 24 hours ahead
  • Keep onion topping separate and fresh
  • Add extra few minutes if baking from cold
  • Have extra onions ready just in case

Common Issues and Solutions

Too watery: Drain beans more thoroughly. Soggy onions: Add them later in baking. Uneven cooking: Stir gently midway. Too thick: Add warm milk gradually.

Ingredients

→ Base Ingredients

01 1 can (10.5 ounces) Campbell's Cream of Mushroom soup

03 1⅓ cups crispy French fried onions, divided

→ Sauce Components

04 ½ cup milk
05 1 teaspoon soy sauce
06 ¼ teaspoon black pepper, or to taste

Instructions

Step 01

Start by giving your 9x9 casserole dish a good coating of cooking spray to prevent sticking.

In a bowl, whisk together the cream of mushroom soup and milk until smooth and lump-free. Stir in the soy sauce for that extra touch of flavor.

Step 04

Mix in your prepared green beans and ⅔ cup of the crispy onions. Season with pepper and give everything a good stir until well combined.

Step 05

Transfer your mixture to the prepared casserole dish, spreading it out evenly.

Step 06

Air Fryer: Bake at 350°F for 10 minutes, stir, top with remaining onions, and cook 2 more minutes. Oven: Bake at 350°F for 25 minutes, stir, add remaining onions, and bake 5 more minutes until golden.
