Ingredients
Scale
- 5 cups frozen cut green beans (see notes for canned or fresh options)
- 1 (12.5 oz) can condensed cream of mushroom soup
- 1½ cups crispy fried onions, divided
- ½ cup whole milk
- ½ teaspoon black pepper
- ¼ teaspoon seasoned salt, plus more to taste
- 1 teaspoon soy sauce
Instructions
- Preheat your oven to 350°F (175°C) and lightly grease a 1.5-quart or 2-quart baking dish with cooking spray or butter.
- Mix the sauce base in a large mixing bowl by combining the condensed cream of mushroom soup, milk, soy sauce, black pepper, and seasoned salt. Stir until everything is smooth and well blended.
- Add the green beans to the bowl with the sauce. Toss to coat all the beans evenly, then fold in 1 cup of the crispy fried onions and stir to combine.
- Transfer the mixture into your prepared baking dish, spreading it out into an even layer with a spatula.
- Bake uncovered for 25 minutes, until the mixture is hot and bubbling around the edges.
- Top with onions by removing the dish from the oven and scattering the remaining ½ cup of crispy fried onions evenly over the surface.
- Return to the oven and bake for an additional 5 minutes, just until the onions on top are golden brown and crispy. Don’t overbake at this stage or they’ll burn.
- Rest for 5 minutes before serving so the casserole sets up slightly and is easier to scoop.
Notes
- Frozen beans: No need to thaw before using. They’ll cook through during the 30-minute bake.
- Canned beans: Use about two 14.5 oz cans, drained and rinsed well. Reduce the bake time slightly since they’re already cooked.
- Fresh beans: Blanch in boiling salted water for 5 minutes, drain, and pat dry before using.
- Make-ahead: Assemble the casserole without the onion topping, cover tightly with plastic wrap, and refrigerate for up to 24 hours. When ready to bake, add the first cup of onions and proceed as directed. Add the topping onions in the last 5 minutes.
- Scaling up: This recipe doubles easily for a crowd. Use a 9×13-inch baking dish and increase the bake time by about 5-10 minutes in the first bake.
- Storage: Leftovers keep in the fridge for up to 3 days in a covered container. Reheat in the oven at 350°F for about 10-15 minutes to bring back some of the crunch.
- Equipment: A 1.5 or 2-quart baking dish works best. A deeper dish means a creamier interior; a wider, shallower dish gives you more crispy edges.
