Ingredient Notes
This recipe has some fresh ingredients that take this casserole to the next level! Want fewer ingredients? Make my 5-ingredient green bean casserole.
- Keep the beans crisp-tender. Trim the ends and cut the fresh green beans in half. Cook them in chicken broth just until crisp-tender. They’ll soften a little more in the oven.
- Drain the beans well. The broth adds flavor while the beans cook. Drain it off completely before mixing the beans with the soup so the sauce stays creamy.
- Can I use frozen green beans? Yes! Microwave or steam them according to the package directions in place of cooking them in broth. Drain them really well before adding them to the casserole. Extra water can make the casserole soggy.
- Can I use canned green beans? If you prefer the softer texture of canned beans, try my 5-ingredient green bean casserole.
- Can I leave out the fresh mushrooms? Yes! You can skip the sliced button mushrooms. The cream of mushroom soup will still give the sauce mushroom flavor.
- Use the condensed soup straight from the can. Stir it in as is, without adding milk or water.
- Crispy fried onions. Store-bought fried onions make this easy, or you can use homemade onion strings. I add the topping just before baking. If you prefer the onions a little less browned, sprinkle them on during the last 10 minutes instead.
How to Make Green Bean Casserole
Cook the vegetables, stir everything together, and let the oven finish the job! This casserole fits right in alongside turkey, mashed potatoes, and stuffing.
- Sauté the Vegetables: Preheat the oven to 350°F. Melt the butter in a large skillet over medium heat. Then, add onions and mushrooms and cook, stirring occasionally, until just tender. Add garlic and cook another 1-2 minutes, then remove from heat and set aside.
- Cook and Drain the Beans: Place the green beans and chicken broth in a medium saucepan. Bring to a boil and cook for about 8 minutes, until the beans are crisp-tender. Drain thoroughly and discard the cooking broth.
- Assemble: Spray a 2-quart baking dish with cooking spray. In a large bowl, stir together the condensed soup, cooked mushroom mixture, drained green beans, Parmesan, salt, and pepper. Transfer to the prepared baking dish and sprinkle with crispy fried onions.
- Bake: Bake for 20 minutes, until the casserole is heated through and the topping is golden. Check the onions toward the end of baking and loosely cover with foil if they’re browning too quickly.
Can You Make Green Bean Casserole Ahead of Time?
Yes! Assemble the casserole up to two days ahead, cover it, and refrigerate it. Keep the crispy fried onions separate until you’re ready to bake.
For the most even baking, take the casserole out of the fridge 30 minutes before it goes in the oven. Sprinkle the onions on top just before baking. If you bake it straight from the fridge, plan on an extra 10 to 15 minutes and check that it’s heated through before serving.
