    1/4 cup of whipping cream doesn't seem like enough liquid. I just made this and many of the onions are still barely cooked, even after an extra 10 minutes

    Thank you for your feedback. If the onions aren't tender enough, you may consider sauteeing them prior to baking.

    I cooked this at 400C for 45 minutes. Also added extra cream as it did not seem to be enough. Delicious

    This was delicious. My family loved it. I had to add extra whipping cream to the sauce to make it more sauce-like. I also sautéed the zucchini, onions and peppers in a skillet with butter until they were soft before adding them to the baking dish. This will be a regular side dish in our family meals. I may double it for family get-togethers, as well.

    Sauteeing all the vegetables a must. I use bacon grease because it’s always in my fridge & FREE & adds flavor. This was great with chicken. Leftovers tomorrow night!

    Made this again tonight. Shortcut: I microwave a frozen bag of peppers & onions while sauteeing the sliced zucchini in bacon grease. Put that in baking dish. Sprinkle most of the mozzarella, poured all the sauce then sprinkled a little more mozzarella before baking. I set the oven to 350 and baked for 30min. Broiled for 2 min to get the cheese crispy brown. Careful not to burn! So good.

    I made this tonight to go with chicken.
    Definitely a ‘keeper’ 😋
    Used cheddar cheese as no mozzarella.
    Cooked for approx 15 minutes extra, placed tin foil over top after 35 minutes to stop any burning.

    As others have said, the amount of cream is not sufficient in this recipe. I had to more than double it to make a creamy sauce. Additionally, after almost an hour at 325, the vegetables were still crunchy, borderline raw ... the taste was fine, but I just put it back in at 350 for another half hour, and hopefully that will fix it, as 2 of the people I was serving it to have no teeth. If almost 90 minutes total isn't enough to fix it, this recipe may hit the trash bin
