Green Bean Casserole Recipe

By  | 

Green bean casserole is one of the most requested side dishes at family gatherings, Easter, Thanksgiving and Christmas!

But this dish not only is a holiday dinner table staple, but is a regular for normal days too. It smells wonderful coming out of the oven, and the fried onion on top give an added crunch. Not only is it oh-so-delicious, it’s easy to make too!

Serve it alongside these easy scalloped potatoes or with this yummy meatloaf.

Green Bean Casserole:

The green bean casserole was actually invented thanks to Campbell Soup Company, one of the biggest soup companies in the United States. They wanted to make a simple recipe with green beans and their canned Cream of Mushroom soup, something everyone had in their kitchen.

Campbell’s green bean casserole recipe helped this dish become the traditional holiday staple it is now.

Today, many variations to the green bean casseroles recipe have been created, but the original remains just as popular, with their canned cream of mushroom soup and French’s French fried onions.

I’m sure many families still have the Campbell’s/French’s green bean casserole on their holiday spread every year. It’s THAT classic!

Green Bean Casserole Ingredients You Will Need

  • 1 pound green beans (fresh or frozen)
  • 4 slices bacon
  • 1 small onion
  • 3 cloves garlic
  • 1/2 pound mushrooms
  • 3 tablespoons butter
  • 3 tablespoons flour
  • 2 1/2 cups half and half
  • 2 teaspoons Italian seasoning
  • 1 1/2 cups parmesan cheese
  • 2 1/2 cups french fried onions

Steps for making green bean casserole

In my green bean casserole recipe, I’ll be using frozen green beans. You can always swap them out for fresh green beans as well.

Some of the cheese will be also used as garnish, along with french fried onions.

How to Make Green Bean Casserole

Now, let’s get cooking! Here’s how you make the best green bean casserole:

First, crisp up the bacon in a skillet over medium high heat and set aside. Chop it up when it is cooled. Wipe up the grease from your skillet, but leave about 1 tablespoon in the pan to fry the mushrooms.

Cook the mushroom, onion, and garlic and set it aside. Steam your green beans until it is the tenderness you’d like.

Then, melt some butter in the skillet, and add in flour and whisk once the butter is completely melted. The mixture will start to thicken in about 30 to 60 seconds. When it does, slowly add in half & half in increments until it gets much thicker.

Add salt, pepper, Italian seasoning, and a cup of parmesan cheese. Stir until the cheese melts. Add in the green beans, mix of chopped bacon, onions, and mushroom, as well as ½ a cup of fried onion.

Move your mixture into a casserole dish. Top with the rest of the parmesan cheese.

Now the dish is prepped for the oven! The last step of the casserole is what ties everything together. It’s what makes a casserole…well, a casserole!

How long do you bake a green bean casserole?

Bake the dish in the oven for 20 minutes. After it’s been baked, take it out of the oven and top with more fried onions until it is completely covered. Bake again for 10 more minutes, or until it’s bubbling.

Tips for Making Green Bean Casserole:

Of course, we all have busier days. What happens when your family is craving your award winning string bean casserole when you simply have no time? Here are a few tips to save some time and still save the good taste:

Swapping out ingredients makes things much easier. For one, I prefer buying the ready-to-steam packages of green beans from the frozen food section. That way, I can just grab it and cook it in one go without having to switch between cooking vessels.  It definitely makes my life easier but doesn’t make the casserole taste any less tasty!

Skip the sauce cooking by replacing with canned cream of mushrooms, just like the original recipe. It’s already seasoned so all you have to do is cook your vegetables and assemble your string bean casserole. This simple hack will definitely lessen your prep time when you’re in a rush. I get just as many compliments when I take this shortcut.

Another way to make it easier for yourself is to change the cooking method completely! Crockpot green bean casserole is another way you prep ahead and not have to rush during dinner time. Simply assemble and cook on low for 5 to 6 hours. Top with the rest of the fried onions once it’s done cooking.
