FAQs
Can I use a different type of pasta instead of medium shells?
Yes, you can substitute medium pasta shells with any short pasta like penne, rigatoni, or fusilli. Just make sure to cook the pasta al dente according to the package instructions.
Can I replace ground beef with another type of meat?
Absolutely! Ground turkey, chicken, or even pork can be used as alternatives to ground beef. This can alter the flavor slightly but will still result in a delicious dish.

Hey, can I just skip the beef and go vegetarian on this casserole, or would that mess the flavor up? Sandra, what do ya think?
I tried it with mushrooms instead of beef, turned out great!
bro, can i just double the beef in this or what
Following this recipe step-by-step, except I may accidentally add chocolate chips. Old habits die hard, right? Sandra, promise it’ll still be edible?
Yeah, because nothing says ‘Italian’ like a casserole. Sounds fake but okay.
im not sure about using medium shells here, dont they get too soft? why not use penne or rigatoni, those hold better
do i gotta use a specific sauce or whatever works?
Just made this casserole, and it’s a hit with my family. Thanks for sharing, Sandra!
looks easy enough, might give it a try
the sauce part is key, got my own secret recipe that would kill in this. Maybe I’ll try mixing it in next time.
can I just eat the pasta raw and call it a day? cooking takes too long lol
Please don’t, your stomach will not thank you!
Does it matter what kind of cheese I use on top? I’m not a fan of anything too strong.
Mozzarella is mild and melts well, perfect for casseroles!
Thanks, I’ll go with mozzarella then!
tried this, wasn’t impressed. seen better.
Felt like I was in Italy with the first bite! Delicious, even if my version didn’t look quite like the picture. Thanks Sandra!
