Ingredients Notes
This recipe calls for fresh or frozen green beans, cream of mushroom soup, milk, soy sauce, black pepper, and crispy fried onions. If you’re opting for fresh green beans, make sure to blanch them beforehand. For a vegetarian option, use a cream of mushroom soup that’s labeled vegetarian or make your own. Crispy fried onions can be found in the baking aisle of most grocery stores, but toasted breadcrumbs can be a great substitute if needed.

Delicious Easy Green Bean Casserole Recipe
Ingredients
- 1 lb fresh green beans trimmed and cut into 1 ½-inch pieces (or use 2 cans, drained)
- 1 10.5 oz can cream of mushroom soup
- 1/2 cup milk
- 1/2 teaspoon soy sauce optional, for depth
- 1/4 teaspoon black pepper
- 1 1/3 cups crispy fried onions divided
- Optional: 1/2 cup shredded cheddar cheese for a cheesy twist
Instructions
- Prep the Green Beans:
- If using fresh beans, bring a pot of salted water to a boil. Add beans and cook for 5–6 minutes until just tender. Drain and rinse with cold water to stop cooking. If using canned beans, simply drain them.

- In a large mixing bowl, whisk together the mushroom soup, milk, soy sauce (if using), and pepper. Stir in the cooked (or drained) green beans and 2/3 cup of the crispy onions. Mix until well coated.
- Assemble:
- Pour the mixture into a greased 9x9 or 2-quart casserole dish. Smooth the top with a spatula.
- Bake:
- Bake at 350°F (175°C) for 25 minutes, or until hot and bubbly. Remove from oven, sprinkle the remaining fried onions (and cheese if using) over the top, and return to the oven for another 5–10 minutes, until golden and crisp.
- Serve:
- Let sit for a few minutes before serving. Pairs perfectly with roasted meats, mashed potatoes, and holiday feasts.
