So if you’re looking for a different cheesy vegetable casserole other than scalloped potatoes or potatoes au gratin, this green veggie version will knock everyones socks off. We have some friends that actually love making this instead of potatoes au gratin because brussels sprouts are much less carbs. There’s a huge difference in carb count between potatoes and brussels sprouts. So this baked this may be less calories than potatoes, but still they’re decent in their own way and everyone once in a while, you have to splurge! Hope you enjoy! We’re obsessed with this recipe.

    Is there a good substite for the flour? I’m on Keto and not sure if Almond flour will mess the recipe up.

    • Best Recipe Box Reply

      Hi Sade, we believe the Almond flour should work and don’t know why it shouldn’t. Please let us know if the almond flour works!

    Making this for Thanksgiving the year! It’s so good.

  9. Sarah Reply

    I would make this again but forgo the mayonnaise. It would save a lot of calories & not taste like ranch.

    Can a non-dairy milk be used with this recipe?

      Hi Kat, we’ve not used any non-dairy milk options yet. But hopefully one of our readers here has and will share their input!

    So I made this deliciousness again last night for dinner but decided to try it as a “casserole dish” I added 3 pieces of chicken tenderloins and it was amazing. Make sure to season your chicken.
