Broccoli Casserole

broccoli casserole

Cheesy broccoli casserole is so much better when you make your cheese sauce from scratch, amirite? Of course I’m right! This recipe is fantastic for Thanksgiving and other holidays that require beaucoup cooking because the cook time and temperature is flexible. Oven’s already preheated to 425? No big deal! Gotta reheat that pie at 350? Also no big deal! Because the broccoli is already partially cooked, and the cheese sauce is hot, all you’re doing in the oven is getting everything melded together. This broccoli casserole makes great leftovers, too, which is an important consideration at Thanksgiving.

    Damn, it’s a pity we’re coming into Summer. This is perfect for Autumn (Fall) and Winter.

      Oh that’s right! It’s so weird to think about a hot Christmas. 🙂

        IIIIIIIII’m dreaming of a hot Christmas…

    I’ve made this! Except slightly different recipe that I got from a really old friend, instead of cheese sauce you put in a tin of cream of chicken soup, a chopped up grilled chicken breast and sliced mushrooms, and pasta shapes. It’s a good way to use up pasta and leftover chicken. Then you top the whole thing with grated cheese and Doritos. Somehow I always managed to squeeze all of that into one dish, just about. It’s a favourite recipe for when you’ve come home really cold and tired and don’t want to cook, and it’s so comforting.

      Yum! You’re right that is a great way to use leftover, Cathy. And a whole meal in one dish! Win-win!

    could one use Brussel Sprouts instead of Broccoli….. love the flavor of the Sprouts….

    • Hilah on November 19, 2013 at 6:26 pm

      That’s an interesting thought, Ron. I think you could. I’d maybe quarter them, lightly steam and continue as directed. Let me know if you like it that way!

    That looks fantastic, Hilah, that is all. 🙂

      Thanks, Kendra! 😀

    Hey! This is making it to my Thanksgiving dinner! My only change will be using bread crumbs in place of the Ritz, just because I forgot to buy them. Also … When I was searching for this recipe in google, one of the first things that popped up was a Huffington Post article about your Chick-Fil-Gay sandwich! I thought that was kind of neat to come across. Thanks for all of the awesome recipes! I also super appreciate that you put up tasty and easy vegetarian recipes!!!

    • Hilah on November 27, 2013 at 11:03 pm

      Yay! That is cool that it is still popping up, Katricia! Thanks for writing and thank you especially for the feedback on vegetarian recipes. I’m going to be doing more in the future. Happy Thanksgiving!

    Hi, Hilah,
    I made this dish last night and it was a hit to my three kids. The 3 year old son kept saying “yummy”. I first found this dish from youtube video search! Thanks!

    • Hilah on December 7, 2013 at 10:39 am

      So glad to hear that, Qi! Thanks for letting me know how you found me, too. That’s helpful. 🙂
