Easy Green Bean Casserole

Easy Green Bean Casserole

One of my favorite Thanksgiving side dishes, besides bowl-full of mashed potatoes and a tub of gravy (DUH!), is this tasty and quite easy green bean casserole.

My kids are crazy about it just as much I am. For us, it is all about the side dishes. Yes, we love oven-roasted turkey, but the sides are the center of attention, at least on our table.

Aleks, my oldest son, makes the best cranberry sauce. On the other hand, my baby girl, Anna, makes her chocolate cupcakes.


I must admit, they are better and better each time she makes them. So, Daniel and I prep side dishes, while hubby just wanders around and entertain family or help each of us for a bit.

Speaking of side dishes, I have posted on my blog garlic mashed potatoes. Seriously, it is out of this world, so you must try it.

I am always really excited about Thanksgiving dinner. I said it a million times before, but for some reason food that we prepare for Thanksgiving or on holidays in general, always tastes so much better.

Perhaps we are all in the holiday mood – music, the aroma of delicious food and laughter, the most important people in our life all wrapped in one house, so of course, a meal tastes phenomenal.

So, my dear readers, I want to share the easiest side dish and I dare to say, it’s the most delicious green bean casserole, and it’s done in less than 30 minutes. 

If you for some reason do not have an oven, and own microwave, yes, you could do it in the microwave or conventional oven. Please use a microwave or conventional oven-safe dish.

As you can see, it is such a simple side dish that could be enjoyed all year round. You can serve it with chicken, fish or any other protein.

I wish you all happy Holiday season from Thanksgiving to January 7th, where we celebrate Orthodox Christmas.

The kids are quite excited to celebrate both so we always make amazing dinner and delicious sweets.

Easy Green Bean Casserole

Yield: 6 Servings
Prep Time: 5 minutes
Cook Time: 25 minutes
Total Time: 30 minutes

Thanksgiving would not be the same without a green bean casserole. This one is easy and very tasty.


  • 2 cans Green Beans 432g in one can (any type -french, regular, string, etc.)
  • 1 jar Mushroom Alfredo Sauce (you can use cream of mushroom soup or chicken condensed soup)
  • 4-5 Mushrooms sliced (cremini, baby Bella or baby Portabella)
  • 2 cups 8oz/1 bag cheddar cheese, shredded
  • Freshly grounded black Pepper a pinch or two


  • 1 container French Fried Onions
  • 5 slices Chopped Crispy Bacon
  • 1/4 tsp. Ground Black Pepper
  • 1 tsp. Dried parsley


  1. Preheat oven to 375°F (190°C).
  2. In a deeper baking dish, add drained green beans.
  3. Pour Mushroom alfredo sauce or you may use more traditional which is cream of mushroom soup, or you might try cream of chicken soup which is also called chicken condensed soup. They are all great, and we like it with all of them but lately preferred MUSHROOM Alfredo Sauce.
  4. Add sliced mushrooms. It is not neccecery but it tastes really good with the addition of mushrooms. Mix the whole thing together to combine.
  5. Top it with cheese completely, from one end to the other, and add ground a bit of ground black pepper on top of the cheese.
  6. Press a bit, and bake for 15 minutes, then add 1 cup of French fried onions and cook for an additional 5 minutes.


  1. Make bacon in the air-fryer or oven until crispy then chop in the small pieces.
  2. Top the casserole with additional french fried onions and chopped bacon.
  3. Add a bit of dried parsley at the very end.


If you don't want to use canned green beans, you can cook frozen or fresh ahead. For fresh you will definitely need a longer time to cook them. For frozen around 20 minutes of cooking at high temperature. Green beans need to be tender. So, pour water above the green beans, cover and crank the heat. Every 5-7 minutes, check to see if you need to add more water, and of course stir. Taste and see if they are tender or not.

If you are using a microwave, I would add french fried onions after cheese is melted. You would need to cook it in the microwave for 6-7 minutes or until cheese is completely melted and cream of chicken soup starts to bubble up, then take the casserole carefully out and add onions.

French fried onions are already crunchy, so to avoid getting them soggy, add them after. This could be also done at the last minute before serving.

NO SALT necessary. Cheese, as well as the cream of mushroom soup, cream of chicken or in this case MUSHROOM Alfredo sauce, have enough sodium.

If you do NOT eat chicken, you can use CREAM OF MUSHROOMS SOUP as a substitute. It's very good either way. Leftovers: Place chilled green bean casserole in an airtight container and keep it for up to 3 days. On that note... I don't like to keep my food for longer than 3 days.

Bacon is, of course, optional, but if you are bacon eater then this is a game-changer. It tastes amazing with it!
