Things have started getting busy at work so I've been looking for a way to stash pre-made meals in the freezer for later. The easiest way I've found to do this is to make a double batch of my favorite casseroles.
To make things even easier, I like to buy ingredients in bulk at BJ's. The larger sizes are perfect for when you are doubling or tripling a low carb recipe.
I also rely on BJ's when friends and family come over for a large gathering. Or, when we are making a large dish to bring to a potluck party.
The prices are less when buying in bulk at BJ's Wholesale Club. Plus, I find it a convenient way feed a crowd or when I make a double size recipe like this chicken Alfredo casserole.
My youngest daughter loves coming along to BJ's for the ride. And, she always enjoys riding in the large shopping cart.
Sometimes, she'll even bring a stuffed animal to sit with her in extra cart seat. She helped me pick out all the ingredients I needed for the recipe: chicken breasts, parmesan cheese, heavy cream, broccoli, cauliflower, mozzarella, butter, and parsley.
Most chicken Alfredo casserole recipes are loaded with high carb pasta. To get carbs down, I replaced the pasta with low carb vegetables.
I used broccoli and cauliflower which are two of the best low carb veggies. To make the casserole easier to eat, I finely chopped both in my food processor.
The cauliflower and broccoli I found at BJ's was already in florets. I find it much more convenient to use when it's already cut up like that.
I also diced up the chicken into small pieces rather than strips. Because everything is chopped, there's no need for a knife or the need to use a fork as a knife to cut things up as you're eating this chicken Alfredo casserole bake.
Another reason I cut things up is because I use a lunch crock at work to heat up my food. And, a spoon works best for me when I'm eating out of the crock container.
You may want to keep the vegetables and meat in bigger pieces if that's what you prefer. The smaller pieces are also much easier for my daughter to eat as well.
I got a good 20 servings which is certainly enough for feeding a hungry crowd. Since I wasn't feeding a lot of people this time around, I ended up freezing half of the casserole for later.
It's going to come in handy for the busy weeks ahead when I won't have much time for cooking. And, the time it took to cook a double batch wasn't longer than what it would take for a regular 9x13 chicken Alfredo casserole.
So, buying larger quantities at BJ's and making larger sized dishes saves me time as well as money. I'll take the savings any day!
It's convenient for me to shop at BJ's as well since it's on the way home from work. And, not only do I save of food there, but gas as well.
You can stock up on all your low carb staples at BJ's. I typically buy meats, nuts, cheese, cream, coconut flour, coconut oil, and fresh produce there.
In addition to this Alfredo casserole, I also like to make my cabbage lasagna in a large size using BJ's products. It's another low carb dish that freezes well.

Oh my goodness. Looks amazing. Making this weekend!

I made this Chicken Alfredo with Broccoli recipe exactly as written. When the instructions say cook sauce until thickened, it must mean cook until very thick. I cooked it until it looked like pasta sauce & it came out runny in the finished dish. Also the top was very brown at 35 mins, so didn’t cook it beyond that.
The taste was good. The veggies were done. I am tempted to make a pot of noodles, toss it together & bake some more. But… then it wouldn’t be Keto.

You can make some adjustments to lower sodium in many recipes such as using lower sodium ingredients.

Hey Lisa,
Do you think precooked chicken chopped up would work? Husband is low-carb to no carb diet. This recipe looks and sounds good. Thanks.
Lisa MarcAurele
Precooked should be fine to use in the recipe.
Angie
Awesome sauce I loved it!!
Bill
Great recipe, my alfredo sauce was nice and thick, the problem I had was it was very runny. What went wrong ?
Lisa MarcAurele
It's likely liquid released from the vegetables.
Lorna
This is delicious! I made it for an event at my church and had many comments on how delicious it was! I made it exactly as the recipe called for. I've even made it and froze it so that I could have it for my lunches. I love alfredo but didn't want noodles and this fit the bill nicely.
Thank you for this great recipe!
Lisa MarcAurele
My pleasure Lorna. I'm so glad the dish was a hit at the church event!
Monica W.
How much sauce does this make? I am planning on using store bought sauce.
Lisa
There's way more sauce than needed. You could get buy with only a couple jars.
Jacqueline
When do I add the parsley? I didn’t see it in the directions.. Mine turned out runny too! Should I use less whipping cream next time? Thank you, we love all your recipes we have tried so far!
Lisa MarcAurele
Liquid from the vegetables is released in cooking. Cutting back on the cream should help.
Robyn
I just made this tonight and it was amazing!!! I scaled it down to 1/4 the size since it's just my husband and I, and I found the sauce to be a little runny. I've never made my own alfredo before, so I'm thinking I didn't simmer it long enough or something? It was on the stove for almost 30 min... you said in a previous comet that you add xantham gum to thicken it - how much do you use?
Oh, and when you say "32 ounces" do you mean 2 lbs? I'm Canadian, so imperial confuses me sometimes lol.
Lisa
Yes. 32 ounces is 2 US pounds.

Best way to make Alfredo sauce is with a simple rue. Equal parts melted butter to flour ( Tbsp). Then adding equal parts cream to cheeses ( usually in cups). The flour helps it thicken properly.
Lisa
But flour has gluten and isn't keto friendly.
Dude
I make Alfredo sauce from scratch:
2-3 cloves of garlic minced
Sauté garlic in real butter 2-3 tbs for like 1 minute
Add 1-2 pints of heavy whipping cream, heat to simmer and whisk every so often
Use sea salt and fresh ground pepper to taste
Fresh chopped dill (optional)
Once it’s been reduced add adagio Parmesan cheese 1/2-1 cup takes about 20 min
Lisa
Thanks for sharing! I've also got a homemade Alfredo sauce recipe.
Milda
Can't wait to try it out. It is cooking now and my home smells amazing. I was just not sure if I should have cooked broccoli to put it in the oven. I added them raw and if there is a bit of crunch to them, that is perfectly fine too!
Lisa
I usually steam a little first.
Karen L
I am making for church pot luck, can I assemble and store then cook tomorrow?
Lisa
Yes. That should work out fine.
Juanita
What do you consider a serving size? 1 cup, 1/2 cup? Thanks!!
Lisa
It's about one and a half cup.
Anika
Man, I usually don't like casseroles but I am new to the low-carb lifestyle and am looking for easy, delicious, interesting dishes I can add in regular rotation and this casserole was amazing. I am so happy I tried it. I lessened the recipe by 4 so I could try it without making such a big batch and I will be making this again. Even my 22 yr old son ate some without much pleading and begging. He thought it was delicious too and that's high praise for vegetables. LOL He actually ate a couple of servings. It's almost gone 🙁
Lisa
I bet you wish you made a bigger batch!
Lauren
How did you reheat it after freezing it?
Lisa
I freeze in single servings and thaw in refrigerator (or lunch bag) and then heat in microwave.
Tiffany LeBlanc
What do you freeze it in?
Lisa
Sometimes a casserole pan and other times (after cooked) in single servings.
Denice Burger
Deliciousness!! I could make a double batch when making the cheesy alfredo and eat half as soup it's so good!! I added finely shredded Gruyere because I had it in addition to the Parmesan and mozzarella for a phenomenal result. Thanks for sharing!!
Lisa
The added Gruyere sounds really yummy.
Rosalind Ross
Excellent!
Nicole
Is this runny? Could you add some noodles?
Lisa
You can add noodles. I add in a little glucomannon or xanthan gum to thicken the sauce.
Jennifer
Can you tell me how large a serving size is?
Lisa
I don't have a feel for weight, but it's about a 2 cup volume.
Ellie Z
what is a lunch crock? sounds like something I need.
Lisa
You can see one here => Lunch Crock Pot
Sara C
Looks great! Do you think this would work in a crock pot (except the cheese browning of course)?
Lisa
It may be a little more runny, but other than that, it should be fine.
