Preheat the oven to 350ºF (175ºC).
In a 9x13 baking dish, add the thawed green beans, half of the crispy fried onions, the mushroom soup, milk, soy sauce, garlic powder, pepper, and salt. Stir to combine.
Bake for 30 minutes.
Stir then top with the remaining crispy fried onions.
Bake for an additional 10 minutes or until the onions are golden brown and the filling is bubbly.
- Frozen cut green beans, thawed: Substitute with 3 pounds fresh green beans, trimmed, or 4 cans (14.5 ounces each) of green beans, drained. Fresh green beans should be trimmed, chopped in half, blanched in boiling water for about 5 minutes, and drained.
- Crispy fried onions, divided: Replace with homemade crispy-fried onions.
- Condensed cream of mushroom soup: Use your preferred "cream of" soup such as cream of chicken or cream of potato.
- Milk: Half-and-half and heavy cream have more fat than whole milk, so they will add extra creaminess.
- Soy sauce: Substitute with Worcestershire sauce or liquid aminos.
- Seasonings: The seasonings can be omitted or adjusted to taste.
- Cheesy: Try this Velveeta green bean casserole for an ultra-creamy and cheesy version. Alternatively, you can add 1 cup of shredded cheddar cheese to the green bean mixture.
- Bacon: Add a few slices of bacon for a smoky, salty bacon green bean casserole.

To store leftover green bean casserole, let it cool to room temperature, then cover it airtight with plastic wrap or aluminum foil, or transfer it to an airtight container. Refrigerate for up to 3 to 4 days or in the freezer for 3 to 4 months.
If frozen, thaw before reheating. Reheat the whole dish in the oven or in single servings in the microwave. Note that the crispy onions may become soggy.
You can make this casserole ahead of time, the day before or several days or weeks before. Simply follow the recipe but hold off on adding the crispy onion topping until the day you bake the casserole.
If making a day or two ahead, cover the casserole with plastic wrap or aluminum foil and refrigerate until ready to bake. If freezing, cover the casserole with plastic wrap or aluminum foil and freeze. Thaw before baking. Bake as instructed, then add the onion topping before the final bake.
No, green bean casserole made with condensed soup typically has a thick and creamy sauce. if the filling is thin and soupy, you may have added too much milk.
This is all about personal preference. Canned green beans are very soft while frozen green beans remain crispy and hold their shape. You can blanch frozen green beans if you like them a little softer.
