Hi, Taylor! I haven’t yet made the recipe, but you are the first person I’ve come across who actually gives a recommendation for freezing individual portions of this pasta bake. I’m working like mad to get my portion control and certain macronutrients the way I need them, let alone being mindful of sodium intake…all the while creating yummy food that’s freezable for the sake of my budget and energy.
I’m also looking at using pastas that are made with stuff like lentils or chickpeas (they’re at my grocery store; I’ve simply yet to experiment with them), just because I want to not constantly spike my blood sugar. ๐ So I may end up trying this recipe with those nontraditional pastas at some point.
But I chiefly wanted to commend you on the recommendation of the foil pans for individual servings. It will make meal prep waaaay easier on me.
Thanks,
Kat

I’m so happy it was helpful! Thank you ๐
Ali says
I have made this very close to the recipe. It was delicious! My husband isn’t a big fan of Rigatoni pasta but he loved the sauce! He loved the sauce so much that he requested I make it again for his birthday but to make thin spaghetti. So in step 3 after I added the red pepper and spinach I kept cooking/simmering until the all ingredients.. red onion, red pepper were soft. Once the sauce and all the goodness was cooked I served over the thin spaghetti. Husband Loved It!! I will making this again for our 20 year anniversary.
Taylor Stinson says
What an amazing compliment, I’m so honored you’ll be making it for your 20th anniversary (congrats!) Thank you so much for sharing your review ๐
Cynthia says
I live alone and am looking for recipes that freeze well. I am looking so forward to trying this!
Mia says
Great flavor and reheats well!
Taylor Stinson says
I’m so happy you like it!
Grace says
I find jn some recipes after you unfreeze the pasta is dry how is this recipe? Is it heat and serve and don’t have to add anymore sauce?
Taylor Stinson says
You can sprinkle some water overtop and then reheat right from frozen in the oven to avoid this recipe from drying out. No more sauce needed!
Becky says
I’m from the UK, I don’t think any stores here sell marinara sauce, what would be the equivalent or could I make it myself?
Thanks Becky
Taylor Stinson says
Hi Becky – any jarred pasta sauce will do!
Anna says
Quick question….are u supposed to fully cook the chicken before u bake it in the oven or does it cook when you bake?? Thanks – cant wait to try this.
Taylor Stinson says
Yes it says in the instructions to cook the chicken first! ๐
Julie A O'Hagan says
I can freeze this in the 9 by 13 glass dish, right? Any advice. Defrost overnight first in fridge?
Taylor Stinson says
Hey Julie – you can if it has a lid but I would avoid this if possible. It would take up way too much room in your freezer and then you would be without your casserole dish. I would recommend dividing the pasta into individual-sized servings in smaller glass containers with lids and freezing from there. To reheat, you can microwave on high for 6-7 minutes from frozen with a little water sprinkled overtop. No need to defrost in the fridge first.
Julie A O'Hagan says
Thanks. But, I want to make it in advance and serve entire casserole to family coming later in month.I have room in my freezer, etc. SO, with that in mind, night you suggest overnight in fridge before cooking? Saran and foil would work , yes? Other advice?
Taylor Stinson says
I would assume this would work! I have not tried this method myself though unfortunately. I have just reheated straight from freezer to microwave or oven.
Alyce says
Ok so do you fully cook in oven and THEN freeze?
Taylor Stinson says
Yes you do!
Emma says
This looks delicious! Just curious -where did you get your 9×13 casserole dish?
Thanks!
Taylor Stinson says
Hey Emma! You can order a 9×13 dish online through Amazon through this affiliate link (https://www.amazon.com/gp/product/B01IUKIPYY/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=thegirlonbloo-20&creative=9325&linkCode=as2&creativeASIN=B01IUKIPYY&linkId=dba5afa019ff5144c2f40e0ed69cf387) or pick one up at any store that sells kitchenware. I believe I got mine at Canadian Tire but you should be able to find one at any department store or kitchen store. Hope that helps!
