Microwave green bean casserole (The tastiest version!)

Microwave green bean casserole (The tastiest version!)

Green bean casserole is inarguably my favorite Thanksgiving dish. I also love to eat it throughout the year, especially when I’m in the mood. 

During summer, though, I’m always looking for ways to avoid heating the oven. This has ultimately led me to cook green bean casserole in the microwave. Since then, I’ve been a massive fan of this approach!

Yes, microwaved green bean casserole is just as delicious as it’s mood-setting. 

The key to making microwaved green bean casserole scrumptious isn’t to overcook it. In essence, you don’t want to overcook those French fried onions. 

Over the years, I’ve tried quite a few variations of the famous green bean casserole. In the end, I think that the traditional recipe is still the best. 

I love using whole milk, cream of mushroom soup, canned green beans, and French’s fried onions.  

Can you cook green bean casserole in the microwave?

Yes, you can absolutely cook green bean casserole in the microwave, and it is easy to do!

It should only take about 15 minutes to prepare and cook the casserole. The important thing is not to overcook it. Also, don’t forget to cook it in a covered dish. 

What kind of beans for green bean casserole?

I prefer the texture of canned cut green beans in my green bean casserole. 

However, you can also make the casserole with fresh green beans or frozen green beans. If you use fresh green beans, make sure to blanch the green beans to be soft. 

Be sure as well that you thoroughly drain your green beans to don’t end up with a soggy casserole. 

What are the ingredients for green bean casserole?

Green bean casserole only requires a few key ingredients.

Green beans: I always make this casserole out of canned green beans. Well, almost always. I don’t recommend french-style cut green beans for this recipe. Be mindful that you don’t buy unsalted green beans. I made this mistake once, and boy was it terrible!

Milk: This is just about the moment to make use of whole milk. Whole milk will make a much creamier green bean casserole. If you’re health-conscious, you can use 2% milk or low-fat milk and still have a respectably yummy casserole.

Mushroom soup: Note that I use cream of mushroom soup in this recipe. Don’t try to get fancy with this ingredient. Go with the standard can of soup. You could make your homemade mushroom soup, but the classics really make this dish.

French fried onions: These crispy fried onions add a crunchy texture to this recipe. I tend to buy two cans and add a bit extra on top. Though, I only put one can in the recipe below, feel free to be like me and go wild with this crunchy treat.

Salt and pepper: Be very careful with your salt here. I do add a tiny bit of salt, but you could get away without adding any extra. The green beans are salted, and so is the soup.

This dish does require some ground black pepper. It’s just needed for that perfect taste.

Can you prepare green bean casserole in advance?

You can put together the green bean casserole in advance and then cook it later. If you’re prepping the casserole ahead of time, just don’t put in the fried onions. Combine all of the ingredients in the casserole dish, except for the fried green onions. When you’re ready to cook the casserole, stir in half of the french fried onions and then cook the casserole as usual.

How to reheat green bean casserole in the microwave

You can reheat leftover green bean casserole in the microwave. We recommend only reheating one serving at a time.

  1. Remove the serving of leftover green bean casserole from the container and place it on a microwave-safe plate. 
  2. Place in the microwave and use the reheat function and reheat in 30-second intervals, stirring in-between until it is hot.
