Au gratin faux-tatoes are very similar in flavor and texture to au gratin potatoes. You can use them in much the same way, too. They are delicious as a side dish, of ?course, but add some diced ham, smoked sausage, bacon, or cooked ground beef between the layers and you have a great main dish casserole, too.
And all for just 6.1 net carbs.
I don’t know about you but I think the holidays are something like walking through a mine field. There is potential for carbs to jump in your mouth around every turn. And yes, I do mean that carbs actually jump in your mouth – I’ve had a mouthful of chocolate cupcake with no recollection of how it got there. Sneaky, sneaky carbs.

Anyway, there are certainly lots of opportunities to fall off the low carb wagon. One things that helps most of us is having low carb versions of the foods we love. This recipe for au gratin faux-tatoes really does have the texture and flavor of regular au gratin potatoes. The cheese sauce is creamy and thick with a little smoky taste from the smoked paprika and almond flour adds the perfect “bread crumb” type of texture.
If you think that “low carb comfort food” is an oxymoron you need to taste this low carb version of potatoes au gratin. Here’s a big plus — it only takes about 3 minutes to make.
The recipe is easy to double or quadruple if you want to make more than one serving. Just make it in a casserole dish and bake at 350F for about 30 minutes, covered with aluminum foil. Take the foil off the last 5 minutes or so to let the almond crumbs get crunchy.
