Ingredients
  

Main Ingredients
  • 4 cups green beans (fresh trimmed and blanched, or frozen and thawed; canned also works—drain well)
  • 1 can cream of mushroom soup (10.5 oz)
  • 1/2 cup milk (whole or 2%) Whole milk gives the creamiest result; use 2% if preferred.
  • 2 cups shredded cheddar cheese, divided Grate your own for better melting.
  • 1 cup French fried onions Plus extra for sprinkling if you like extra crunch.
  • Salt and black pepper to taste

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish or similar size.
  2. In a large bowl, whisk together the cream of mushroom soup and milk until smooth. Season with a pinch of salt and a few turns of black pepper.
  3. Add the green beans to the bowl and stir until evenly coated in the mushroom mixture.
  4. Fold in half of the shredded cheddar cheese so there are pockets of melty cheese throughout.
  5. Transfer the mixture into the prepared baking dish and spread it into an even layer.
  6. Sprinkle the remaining cheddar cheese over the top, then scatter the French fried onions evenly.
Baking
  1. Bake for 25–30 minutes, or until the casserole is bubbling and the top is golden brown.
  2. Let rest for 5 minutes before serving so it sets slightly. Serve warm.

Notes

For dairy-free: use a dairy-free cream soup and plant-based milk, plus a vegan cheddar alternative. For a richer flavor, swap half the cheddar for Gruyère or sharp white cheddar.
