    Can you freeze to make ahead? Before or after cooking is best? Thank you.

    This tastes just like what my mom makes. It's a great squash recipe!

    This is the same as my Nanny used to make. She never seeded the squash. Also her recipe says Ritz or any other cracker. Thanks!

    This was so delicious! I added 1 1.2 tsp. of sugar and did not peel or de-seed the squash. I just diced it using my onion chopper. I'll definitely make this again!

    Used both zucchini and yellow squash. DRAIN WELL. Sautéed onions and sliced portabello. mushrooms. LOTS OF CHEESE.

    I can definitely tell that this had potential, but something didn't quite work well with mine. It came out too mushy and oily. I melted the butter so maybe that was the problem. Or maybe I didn't drain the squash well enough after boiling it. In the end, it just seemed like there was too much butter. I may try it again or read through more reviews to see if there is a solution to my problem because I can tell that otherwise the taste would be very yummy, reminiscent a bit of butternut squash bisque. Also, I see that some people say the onion wasn't cooked well enough - that wasn't a problem for me. I used my slap chop to make it really fine, perhaps they just need to be really tiny pieces in order to be cooked all the way through.

    OMG this is awesome! We love squash anyway but this casserole it delicious. I used a whole sleeve of crackers and also subbed 1/2 cup of milk in place of the butter. We will definitely be having this alot in the summer. Thank you for the recipe!!
