How to Make Buttermilk Potatoes Au Gratin

Alright, let’s plunge into the delicious world of Buttermilk Potatoes Au Gratin. First off, you’ll want to preheat your oven to a cozy 350°F. While that’s warming up, grab those 2 lbs of red baby potatoes and slice them thinly. The thinner, the better, because we want them to cook evenly and soak up all that creamy goodness.
Toss those sliced potatoes into a saucepan, cover them with enough salted water, and bring it to a boil. This is where patience comes in—let them cook for about 12 minutes until they’re just tender. You want them to hold their shape but be soft enough to melt in your mouth. Once they’re done, drain the potatoes and set them aside for a moment.
Now, let’s whip up that creamy sauce. In a separate bowl, prepare the 1 ½ ounces of Knorr four cheese pasta sauce mix according to the package directions, but here’s the twist—substitute 1 ½ cups of buttermilk for the regular milk. This is where the magic happens; buttermilk adds a rich, tangy flavor that makes your potatoes sing.
Stir in 2 tablespoons of chopped chives and a splash of Dijon mustard—start with 1 tablespoon and add more if you’re feeling bold. This flavor combination is where you can really get creative, so don’t be shy! Once your sauce is ready, save about ½ cup of it for later, and mix the rest with the potatoes in a large bowl.
Next, find yourself a 1 ½ quart ovenproof casserole dish and spoon that potato-sauce mixture right in. It might look a little messy, but trust me, it’s going to turn into something heavenly.
Pop it in the oven and let it bake uncovered for 20 minutes. Here’s a little tip: pour that reserved sauce over the potatoes during the last 5 minutes of baking. It’s like a little gift you give to your dish right before it’s ready to shine.
Once it’s out of the oven, sprinkle on the remaining 2 tablespoons of chives, and voilà! You’ve got a beautiful, bubbly Buttermilk Potatoes Au Gratin ready to impress your family or friends. Just try to resist the urge to plunge in immediately; it’s hard, I know. Enjoy!
