    I made this recipe (cut in half for a single person) and this is awesome. I'm on vacation and this recipe sounded easy and delicious. Just ate 1/2 the pan.

    Made this last night as I had pretty much everything in the fridge. Used leek instead of shallot and 2% milk instead of heavy cream. Didn't have panko bread but made some croutons which I broke up coursley. I also added some fresh tarragon. This is so good and so flexible. I will make it many times over the summer with fresh squash. Thanks for a very good recipe. Know my friends are going to love it with fresh fish.

    Squash is not my favorite vegetable, so I rarely cook with it. This recipe was delicious! I added 3 cheese kielbasa and made it a main dish.

    I made this dish tonight and it was fabulous! In fact, my husband has NEVER taken seconds of any kind of squash dish but he had a second helping of this one. I made it because the reviews were so great but this recipe actually lives up to the 5 stars rating. I'm a 'little bit of this' and a 'little bit of that' kind of cook but this recipe I made exactly as written. I won't change a thing. In fact, my husband is planting some squash plants right now ....... which is a first!! Great job Taste of Home!!

    Yum!! A new family favorite!! Even the non-squash/zucchini eaters liked it! Fast and easy side dish.

    I have made this time and time again and it is the best recipe for squash. Very easy as well and have given this recipe out to countless friends.

    This squash casserole is not as creamy as others I have made, but it lets the flavor of the squash and zucchini shine through. I enjoyed this easy to make dish.

    This is delicious! It’s April now, I had some store-bought squash to use up, but I can’t wait until the glut of summer gardens gives me reason to make this often!! Very simple recipe and tastes so rich! Ok, so the heavy cream and cheese helps, but the amounts of each that are used are reasonable. I salted my cut squash, let them stand a little while and rinsed before cooking to cut back on moisture a little, but otherwise followed the recipe. I might try to switch out the cheese for something like Swiss or gruyere or Gouda, just for variety. Very good side dish!
