What To Serve With Easy Green Bean Casserole Recipe?

This Thanksgiving or string bean casserole goes well with other Fall sides such as Candied Carrots (One Pot), Oven Roasted Sweet Potatoes (One Pan), or Creamy Mashed Potatoes Recipe (One Pot),

Roasted vegetables such as Oven Roasted Cauliflower (One Pan), Oven Roasted Broccoli (One Pan), Oven Roasted Asparagus (One Pan), or a veggie combo like this Oven Roasted Vegetables (One Pan), make a great pairing as well.

Storage

Refrigerate– In a sealed container in the fridge for up to 2 days.

Freeze- In a freezer safe container (without the fried onions on top) for up to 1 month.

Reheat– In the microwave or stovetop, noting that the fried onions will no longer be crispy.

Variations

Green bean casserole with cheese– Add shredded mozzarella or cheddar, Parmesan, Gouda, or even Swiss cheese.

Fresh green bean casserole– Use fresh green beans that are washed and trimmed.

Loaded green bean casserole– Add bacon crumbles and top it with chives and sour cream.

Healthy vegan green bean casserole (dairy free)- Use vegan butter and vegan cream of mushroom soup, and almond milk in place of whole milk.

Use cream of chicken– In place of cream of mushroom soup if you prefer.

Make it gluten- free– Use gluten free fried onions, and coconut aminos instead of soy sauce.

Add seasoning– Such as Italian, Mexican, Cajun, or Greek seasoning for a flavor twist.

Make it spicy– Add crushed red chili flakes or even jalapeno slices for a good spicy version.

Add nuts– add toasted walnuts, pecans, or almonds to the topping.

Add other vegetables– such as caramelized onions or red bell peppers.

Tips And Techniques

Fresh green beans vs. canned green beans– I used canned green beans to save time, but you can use fresh green beans that are washed and trimmed just as easily.

Cream of mushroom soup substitute– You can use cream of chicken, cream of celery, or even sour cream with finely diced mushrooms, if you prefer.

Must use whole milk– This adds to the richness, creaminess, and best flavor.

Drain and rinse the canned green beans– This washes off all the preservatives, and also ensures that the casserole does not contain too much liquid.

Adjust seasoning– Add more or less based on your personal preference.

Bake uncovered– This helps provide the best texture, there is no need to bake it covered.
