Ingredients
Scale
- 12 oz (340g) frozen green beans
- 1 can (10.5 oz / 298g) cream of mushroom soup
- ½ cup (120ml) milk
- 1 tablespoon (15ml) soy sauce
- ½ teaspoon (1g) black pepper
- 1½ cups (about 85g) French’s crispy fried onions
- Optional: ¼ teaspoon garlic powder, shredded cheddar cheese
Instructions
- Preheat oven to 350°F (175°C). Let frozen green beans thaw for 5-10 minutes, then drain and pat dry.
- In a large mixing bowl, combine cream of mushroom soup, milk, soy sauce, and black pepper. Stir until smooth.
- Add drained green beans to the bowl and stir gently until all beans are coated.
- Fold in ½ cup of the crispy fried onions.
- Pour mixture into a greased 1½-quart baking dish and spread evenly.
- Bake uncovered for 25 minutes until bubbly around edges and slightly set.
- Remove from oven, sprinkle remaining 1 cup of crispy fried onions evenly over the top.
- Return to oven and bake for another 5-7 minutes until onions are golden and fragrant.
- Let casserole rest for 5 minutes before serving.
Notes
For best texture, layer half the fried onions in the middle and half on top. Let the casserole rest 5 minutes before serving to allow the sauce to thicken. To make ahead, assemble without top onions and refrigerate up to 24 hours; add 10 minutes to bake time. For a dairy-free version, use dairy-free cream of mushroom soup and unsweetened oat or almond milk.
