Healthy Potatoes Au Gratin

I’ll spare you a lengthy intro about the origins of potatoes au gratin because, well, I don’t really know or care where this tasty dish came from. I’m just happy to have it. 

Instead, I’d like to briefly explain what makes these creamy potatoes au gratin healthy since healthy can mean something different for everyone. 

If you’re unfamiliar with my blog, I primarily make lower calorie, higher protein recipes. There are no ingredients off limits, and things like cheddar powder in these potatoes au gratin create loads of flavor while keeping calories under control. Because, in my opinion, losing body fat is one of the healthiest moves you can make.

Ingredients for Healthy Potatoes Au Gratin

In addition to making my recipes healthier, I like to think I specialize in making them simple, too. And this recipe is no exception. Here’s a look at almost everything you’ll need: 

  • russet potatoes (or your choice of potato)
  • skim milk
  • fat free Greek yogurt
  • light butter 
  • shredded cheddar and mozzarella 

These are all customizable, as always. Want to use almond milk, do it to it. Rather have all cheddar? It’s your world.

Okay, I said almost everything you need because there’s one ingredient you may not be familiar with—cheddar powder. I’ll fill you in below. 

What is Cheddar Powder?

I always compare this magical ingredient to powdered peanut butter. It’s essentially dehydrated cheddar cheese in powder form that can be reconstituted for cheese sauce or added straight to things like popcorn or chips for cheddar flavor. 

Similar to powdered peanut butter, this process removes most of the fat and you’re left with a much lower calorie option. You’re able to get tons of cheddar flavor without the calories of adding real cheese.

Is cheddar powder the healthiest ingredient out there? No, of course not. But like anything, it’s perfectly fine in moderation. 

For my recipes, I use Hoosier Hill Farms or Anthony’s. You can find both on my Amazon products list. 

If you don’t have any cheddar powder on hand, you could make a traditional cheese sauce like in my bacon gouda breakfast enchiladas recipe. You can also get away with using the powdered cheese from boxed mac and cheese in a pinch.

Final Recipe Notes

With the longer cook time and oven/baking dish variance, you may have to tinker a tiny bit with cook time. The photos below show the potatoes after I uncovered them at the 45-minute mark (left) and after topping with shredded cheese (right). Get close to that and you’ll be just fine.
