Grandma’s Green Bean Casserole Recipe

Perfect for a weeknight dinner or a holiday side dish, this is the best green bean casserole to make if you want an original recipe that packs in the flavor (without the cream of mushroom soup).

The buttery cracker topping sprinkled over the cheese seals in the rich and savory flavor of the green beans below it.

Although there are a lot of similar recipes out there, this one is unique in that it’s fast to make and even if it’s the first time, second time, or twentieth time you’re making it, your family will never get sick of it!

Ingredients Needed

• Sweet onion – In this onion version, I chose fresh onion over fried onion rings. Swap out for white or yellow onion if needed.
• Mushrooms – Most recipes call for the standard mushroom soup, but I prefer the taste of fresh mushrooms. Can substitute canned, sliced mushrooms.
• Sour cream – Substitute for plain Greek yogurt if needed.
• Worcestershire sauce – You can create a replacement sauce with soy sauce, white wine vinegar, and ketchup if you need to. 
• Cut green beans – Although the recipe calls for cans of green beans, you can choose fresh green beans, or substitute with the frozen equivalent.
• Sharp cheddar cheese – Substitute with Swiss cheese if you can’t find cheddar. 
• Ritz crackers – If necessary, melt butter and mix with bread crumbs or panko instead.
• Kitchen Staples – Butter, all purpose flour, black pepper, garlic powder, milk.

How to Make Grandma’s Green Bean Casserole

Can I make it ahead of time?

Yes, this green bean casserole can be made ahead and stored in the fridge for up to 3 days in an airtight container.

Leave off the cracker crumbs, and add to the top when you reheat it according to the directions.

If it gets a little dry, add in some chicken broth to help rehydrate it before putting it in the oven or microwave.

Can I freeze it?

Store in the freezer for up to 6 months, and thaw in the refrigerator until the next day when ready to eat.

Reheat according to the instructions in the recipe card.

Serving Suggestions

Since this is a Thanksgiving style meal, it goes well with any sides that you’d typically find on the table – from turkey and cranberry sauce to mashed potatoes and biscuits!

Thanksgiving won’t be complete without the cranberry somewhere. How about skipping the can poured out into a dish and make this cranberry casserole.

And the other delicious parts of this holiday are the amazing desserts. I love a simple bundt cake slathered with White Chocolate Cream Cheese Frosting. You can’t go wrong with this!

How do I keep green bean casserole from getting soggy?

It’s best to drain the beans as best you can. And start with just lightly blanched beans that are still crisp tender.

Tips for the Best Casserole

• If you’re a cheese lover, the only things that you need to mix are your cracker crumbs with some parmesan cheese for an extra gooey topping! 
• For more crunch on top of your casserole, you can add french-fried onions to the topping. 
• Choose green beans that are french cut if possible. If canned, choose cans of french style green beans. 
• To prep your fresh green beans, boil them for around 6 minutes before transferring them to an ice bath using a slotted spoon. 
• Allow guests to add a teaspoon of salt or pepper to taste.
• If you prefer more crunch, swap out the breadcrumb topping for Crunchy French’s onions.
