Ingredients
Scale
Main Ingredients:
- 2 lbs fresh green beans
- 1 cup french fried onions
Sauce and Dairy:
- 1 can (10.5 ounces) cream of mushroom soup
- ½ cup milk
- ½ cup sour cream
- ½ cup grated parmesan cheese
Seasonings and Extras:
- ¼ cup butter
- ½ teaspoon black pepper
- ¼ teaspoon salt
Instructions
- Snip off green bean ends and slice them into 2-inch segments. Rinse beans thoroughly under cool water.
- Bring a large pot of salted water to a rolling boil at 212°F. Drop green beans into boiling water for exactly 3-4 minutes until they turn bright emerald green.
- Immediately drain beans and plunge them into an ice water bath to halt cooking process. This keeps your beans perfectly crisp.
- Preheat your oven to 375°F, ensuring the rack is positioned in the center.
- In a spacious mixing bowl, whisk together 10.5 oz cream of mushroom soup, ½ cup milk, ½ cup sour cream, ¼ tsp salt, and ½ tsp black pepper until smoothly combined.
- Thoroughly drain blanched beans and pat them completely dry with paper towels to prevent watery casserole.
- Gently fold dried beans into soup mixture, ensuring every bean gets evenly coated.
- Transfer bean mixture into a 9×13 inch baking dish, spreading it out evenly.
- Melt ¼ cup butter and combine with 1 cup french fried onions and ½ cup parmesan cheese.
- Sprinkle onion-cheese blend across the casserole’s surface, creating an even layer.
- Bake uncovered at 375°F for 25-30 minutes until the topping turns golden and edges bubble.
- Remove from oven and let casserole rest 5-10 minutes before serving to set and cool slightly.
Notes
- Fresh green beans make a huge difference, so select crisp, bright green beans without blemishes or soft spots.
- Always blanch and shock green beans to keep their vibrant color and prevent overcooking, which leads to mushy texture.
- Use full-fat dairy for the richest, creamiest casserole, as low-fat versions can separate during baking and create a less smooth sauce.
- For a gluten-free version, swap cream of mushroom soup for a homemade version using gluten-free flour and replace french fried onions with crushed gluten-free crackers or nuts.
