For decades, people have relied on green bean casserole to provide a simple but hearty meal. I’m sure we all have memories of eating it while growing up and also learning to make it for ourselves as adults. But one thing that folks may not know is that you don’t have to wait until green beans are in season. You also don’t have to fuss about making sure the fresh green beans are perfect and ready to cook. This is because the best green bean casserole is one that’s made with frozen green beans.

Remember that frozen green beans are often blanched and flash-frozen during the height of green bean season. That means you’re using quality green beans that are ready to cook and eat. Of course, with the green beans taken care of, the rest of the recipe is a breeze. There are just a few more ingredients to add for an easy and convenient dinner that you know is going to be a crowd-pleaser that satisfies everyone at the table.

While I recommend green bean casserole with frozen green beans, if you have dietary restrictions, there are other options. You can also make either a Vegan Green Bean Casserole or a Low-Carb Keto Green Bean Casserole. If you’re just looking for a side dish, I suggest Instant Pot Green Beans. Finally, if you’re just a big fan of casseroles and want some new recipes to try, I suggest this recipe for a Keto Chicken Casserole.

Is Green Bean Casserole with Frozen Green Beans Healthy?

Green bean casserole with frozen green beans should be a healthy recipe for most diets. Even though the sodium levels are low enough for most people, the saturated fat is a little high. However, green beans are naturally high in vitamin K and calcium, so they are particularly good for bone health. The mushroom soup in the recipe also provides niacin, potassium, and other minerals the body needs.

It’s the Seasoning…

The seasoning tends to be one of the most overlooked parts of green bean casserole. If your diet allows for it, don’t skimp on the salt and pepper because that will add plenty of flavor to the dish. There are also times when I add a dash of nutmeg or slice a red onion to add a little more flavor and texture to the casserole. Finally, when it’s time to add the crispy fried onions on top, consider adding breadcrumbs or panko to the mixture as well to give the casserole even more crunch.

FAQs & Tips

How to Make Ahead and Store

Green bean casserole can be prepared ahead of time and left covered in the fridge until you’re ready to cook it. Let it sit at room temperature for about 30 minutes before putting it in the oven. Once cooked, keep leftovers in the refrigerator for no longer than 4 days, and remember the longer you leave it the soggier the onions tend to become.

How do I prevent a watery casserole?

If you sense that the casserole is a little watery, before baking it, add a thickener like starch to help absorb some of the excess water.

Serving Suggestions

If you’re making green bean casserole as the main dish, there are plenty of side dishes that go well with it. One of the classic choices is Healthy Mashed Potatoes, although you can switch things up and make Mashed Red Potatoes. I also like the idea of doubling down on vegetables and pairing green bean casserole with a Kale Salad with Cranberries. Finally, if you’re looking to add a little meat to the meal, I would suggest making Sweet and Sour Paleo Meatballs or a batch of Air Fryer Chicken Tenders that I guarantee will turn out crispy.
