- 1 can (10.5 oz) cream of mushroom soup
- 1/2 cup whole milk (or dairy-free alternative)
- 1 cup fried onions (store-bought or homemade)
- Salt and pepper to taste
Instructions
- Step 1: Rinse the green beans under cold water and trim the ends.
- Step 2: Blanch the green beans in boiling salted water for 3-4 minutes, then drain and plunge them into ice water to stop the cooking process.
- Step 3: In a large bowl, combine the cream of mushroom soup with milk, seasoning with salt and pepper to taste.
- Step 4: Gently fold the blanched green beans into the soup mixture, ensuring they are evenly coated.
- Step 5: Transfer the mixture to a greased baking dish, top with fried onions, and bake at 350°F for 25-30 minutes until bubbly and golden on top.
Tips & Variations
- For extra flavor, add a teaspoon of soy sauce or Worcestershire sauce to the soup mixture before baking.
- Use fresh homemade fried onions for a crispier and less salty topping.
- Swap out cream of mushroom soup for cream of celery or cream of chicken for a different twist.
- Add shredded cheddar cheese on top before baking for a cheesy variation.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through to keep the topping crispy, or microwave for a quicker option though it may soften the onions.
