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.

So if you’re wondering how creamy, cheesy potatoes could possibly be healthy, it’s because you’d be pressed to find another potatoes au gratin recipe with 18 grams of protein and just 21 grams of carbs per serving! 

Ingredients for Buffed Up 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 are two ingredients that you may not be familiar with—cheddar powder and collagen peptides (unflavored protein powder). I’ll fill you in about both ingredients and substitutions 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.

What are Collagen Peptides? 

Collagen is a structural protein and is known for supporting for hair, skin, nail, and joint health. In supplement form, collagen peptides are a tasteless powder (in most cases) that provide 20 grams of protein per serving. Or at least the Bowmar Nutrition Collagen Peptides I used for this recipe provide 20 grams per serving. 

Since they’re tasteless, they’re perfect for savory recipes like these potatoes au gratin. They add 60 grams of protein and, in combination with the cheddar powder, act as a thickener for the cheese sauce. 

I guess you could say they’re as vital to the structure of this recipe as they are to your joints. Ba dum tiss.

Since this ingredient isn’t all that common, you could get away with another unflavored protein powder if you have it on hand. Or if you want to skip the protein altogether, you could scale back on the liquid ingredients a bit. I haven’t tested it, but I’d guess reducing 1/2 to 1 cup of milk would do the trick. 

Final Recipe Notes

With the longer cook time and oven variance, you may have to tinker a tiny bit with cook time. My biggest tip is to cook for the full 60 minutes before uncovering to let the potatoes fully cook. Once you uncover the potatoes, the remaining liquid will quickly cook off and you can melt the cheese on top at the very end. 

Yum.
