Green Bean Casserole with Frozen Green Beans
We have made this oven baked green bean casserole with bacon for years and years. I am sure you remember this dish at every holiday. Itโs probably always been baked in the oven though huh? Well this year should be different.
Easy is the name of the game right? Itโs a pain rotating all those dishes in your oven and worrying that your Cheesy Green Bean Casserole will get cold. Thereโs just no way of ensuring it all comes out at the same time, and sometimes dinner lasts a long time. We have a solution for that if you use some countertop appliances. Hereโs how you avoid that.
Which is better in green bean casserole, canned or frozen beans?
That depends on whom you ask but the harder they are to begin with the less they will fall apart so I like frozen. Totally opposed to that? Okay, well then grab some fresh in your produce section and use those instead. Just stay away from canned unless you like a REALLY soft texture to your food. This is what was used below:
For all the varieties I share on The Typical Mom I recommend frozen green beans for sure. The texture holds up so much better. Nobody wants mush next to their slices of slow cooker turkey or Crockpot ham. It is also a cheaper way to go. Get them already cleaned, the ends cut off and sliced in half typically.
No, there isnโt a ton of variation to this dish on the whole. Beyond adding bacon and whether you want to make your own crunchy onions it remains the same. BUT there is a difference when it comes to the beans you use.
We live in a small town too so there arenโt always fresh available in the Wintertime so this option is a must. Like I said though even if I had the choice of both I would go with frozen bagged because the texture when it is done is so much better. Trust me and try them this way, then decide for yourself.
Ingredient Tips
- Fresh or frozen green beans are by far the best because in this long cook time you donโt want the texture to turn to mush. Starting from rock hard will help avoid this.
- Cream of mushroom soup or any condensed creamed soup flavors in the can are fine or make cream of mushroom homemade if you prefer
- Milk 2% or whole is best to keep it nice and thick, you could use a dairy free alternative just fine, choose plain cashew for best results
- Parmesan cheese may be a bit different than other versions but a great add in for Thanksgiving dinner
- Salt and black pepper and any other seasonings that are a must in your book, sprinkle those in
with Bacon
If you wanted to add more flavor and texture you can do so with diced bits of meat. You would want an and all to be precooked before adding but this makes a great leftover ham recipe and bacon bits in it are the most common favorites.
Once you have the ingredients you just throw it all in and stir to coat each piece. Then itโs ready for take off. Like the original version โback in the dayโ you leave most of the crunchies for the top!
The biggest difference for this version is they wonโt get browned, unless you take out the liner and broil for a few minutes. If you are serving brunch you could just leave a bowl of them on the side for people to top as they like.
Can you mix up green bean casserole the night before?
That would be a hard NO from me. For one thing the beans would no longer be frozen and would soften too much while cooking. Secondly the onions would be icky. It literally takes 5 minutes so just do it the day of.
What to serve this with
- Oven baked ham is a game changer with this bourbon glaze.
- For faster service try this Ninja Foodi ham recipe.
- Not a fan of either? Try Fall-Apart Brisket in the Oven here with a dry rub.
- We just baked sweet potato cubes in the oven once and will be making those on the big day.
- Of course our air fryer vegetables are served year round.
- Instant Pot corn is super cheap and only takes a few minutes to cook.
- And we canโt have a get together without this Jiffy corn casserole recipe.
- If this is for the holiday season you could combine these two favorites to make green bean mashed potato casserole too.

How long does green bean casserole last?
If you do have leftovers you should transfer them (once room temperature) into airtight containers. They will last about 3 days and reheated later to enjoy. Same goes for Sweet Potato Casserole with Canned Yams and pressure cooker mashed potatoes. I will say the next day is best for sure. Remember that the texture will change and it will get softer over time.
Does green bean casserole freeze well?
It does. I personally feel like the texture does get altered if you do though. It will last at least 3 months if frozen vs. storing it in your freezer. For reheating youโd need to let it defrost though, then microwave and stir every 30 seconds.
If you know you wonโt eat whatโs left in the next 2 days or so I would opt for this option. I like to use smaller containers that are 1 serving size so you can just take out and warm for one meal at a time. It will make them last longer.
How do you save your leftovers? This actually saves quite well so you can enjoy it the next day. I am sure you will have some meat left so donโt get rid of any of this, they go really well together.
Just store in airtight containers or bags in the fridge. Reheat for about 1 minute in the microwave stirring halfway through. You could use an air fryer pot and put some in there too. At 380 for about 6 minutes that will do the trick too. Top with new crispy onions on top for the last minute and it wonโt be as mushy as without.
How to make this faster
Want to make this faster? You can make this into Instant Pot green bean casserole too. If you need it done quickly this may be the answer. If I had a choice I prefer that it cooks low and slow all day in my Crock.
Yes there is a slow cooker function on Instant Pots and other pressure cooker brands but to be honest it doesnโt work that well. I am not sure why this is other than the fact that the pot inside isnโt as wide but others agree with me too. Itโs better just to go back to your โold fashionedโ porcelain pot.
If youโre making this for your family during the holidays, enjoy my friends. I love this time of year so we can all enjoy good food and reminisce on good times in the past.
