| All-purpose Flour | 1/4 cup | |
| Unsweetened Almond Milk | 1 1/2 cups | |

| Salt | 3/4 teaspoon | plus more to taste |

Ingredient Notes for Your Dad’s Creamy & Cheesy Au Gratin Potatoes
Let’s chat about a couple of these ingredients, because they really make a difference! Yukon Gold potatoes are my absolute go-to for au gratin. They have this lovely creamy texture and just the right amount of starch, which means they cook up tender without getting mushy. Plus, their naturally buttery flavor is just *chef’s kiss*.
Now, about the cheese! Sharp cheddar is non-negotiable for that classic, comforting flavor. But adding Gruyere? Oh, that’s a game-changer! It brings this wonderful nutty, slightly sweet depth that just melts beautifully. If you can’t find Gruyere, don’t sweat it – just use more sharp cheddar. And for the milk, unsweetened almond milk works like a dream here and keeps it light, but feel free to use regular milk if that’s what you have on hand. It’s all about that creamy, cheesy goodness!
Step-by-Step Instructions for Dad’s Creamy & Cheesy Au Gratin Potatoes
Alright, let’s get cooking! Making these au gratin potatoes is a journey, but trust me, it’s one that ends in pure deliciousness. We’ll build this dish layer by layer, making sure every step brings us closer to that perfect, bubbly, cheesy casserole. It’s not complicated, but a little care goes a long way!
Preparing the Potatoes and Onions
First things first, get that oven preheating to 375 degrees Fahrenheit. While it’s warming up, grab your baking dish – a nice 2-quart square one is perfect. Now, take those thinly sliced potatoes and arrange them in the dish. I like to do it in slightly overlapping, slanted rows. It just looks pretty! Then, tuck those sliced onions in between and on top of the potatoes. This even distribution is key for making sure everything cooks up perfectly tender.
Crafting the Creamy Cheese Sauce
Time for the star of the show: the sauce! Melt your butter in a medium saucepan over medium heat. Once it’s all gooey and bubbly, whisk in the flour. Keep whisking for about a minute – this cooks out that raw flour taste. Then, slowly, and I mean *slowly*, start pouring in the almond milk, whisking like crazy the whole time. This is how we avoid lumps, which nobody wants in their au gratin! Keep simmering and whisking until the sauce thickens up to a nice, gravy-like consistency. Now, turn the heat way down to low. It’s time for the cheese! Stir in the shredded cheddar, garlic powder, salt, and pepper. Keep stirring until it’s all smooth and melted. Give it a taste – does it need a little more salt? A bit more pepper? Make it perfect for *you*!
Baking Your Dad’s Creamy & Cheesy Au Gratin Potatoes to Perfection
Okay, pour that glorious cheese sauce evenly over the potatoes and onions in your baking dish. Make sure it gets all over! Now, cover the whole thing tightly with foil. Pop it into that preheated oven for about 45 minutes. This is where the magic starts to happen underground, letting those potatoes soften up beautifully. After 45 minutes, carefully remove the foil. Be careful of the steam – it’s hot! Sprinkle that lovely Gruyere cheese all over the top, followed by the grated Parmesan. Pop it back in the oven, uncovered this time, for another 30 to 45 minutes. You’re looking for tender potatoes (a fork should slide in easily!) and a gorgeously golden-brown, bubbly topping. Once it’s perfect, pull it out and let it rest for a few minutes before garnishing with fresh parsley. That little bit of green makes it look extra special!
Essential Equipment for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
To bring this amazing dish to life, you don’t need anything too fancy. Just your trusty kitchen basics! Having the right tools makes the whole process so much smoother, and honestly, more enjoyable. Here’s what you’ll want to have ready:
| 2-quart square baking dish | This is where all the cheesy potato goodness will bake up beautifully. Make sure it’s deep enough! |
| Saucepan | A medium-sized one is perfect for whipping up that luscious cheese sauce. |
| Whisk | Your best friend for getting that sauce silky smooth and lump-free. |
| Measuring cups and spoons | Precision is key here, especially for the sauce ingredients! |
| Knife | A good sharp knife makes slicing those potatoes and onions a breeze. |
| Cutting board | For safe and easy slicing. |
| Oven mitts | Essential for safely handling that hot baking dish straight from the oven. |
Tips for Making the Best Dad’s Creamy & Cheesy Au Gratin Potatoes
Want your Dad’s Creamy & Cheesy Au Gratin Potatoes to be absolutely perfect every single time? A few little tricks can make all the difference! First off, slicing those potatoes uniformly is super important. If some are way thicker than others, they won’t cook evenly, and nobody wants crunchy bits mixed with mushy ones! A mandoline slicer is your best friend here if you have one, but just take your time with a sharp knife.
When you’re making that glorious cheese sauce, don’t rush it. Whisking constantly as you add the milk is the secret to a super smooth, lump-free sauce. If it seems a little too thin after you’ve melted the cheese, don’t panic! Just let it simmer gently for another minute or two, stirring, and it should thicken up. To avoid a watery gratin, make sure you’re using good quality cheese that melts well and not pre-shredded stuff that often has anti-caking agents. And for that gorgeous golden-brown topping? Make sure your oven is fully preheated before you pop that foil-covered dish back in for the final bake. That’s where the real caramelization happens!
Variations on Dad’s Creamy & Cheesy Au Gratin Potatoes
While this recipe is absolutely perfect as is, I love playing around with it to make it even more special! If you’re feeling adventurous, try adding some thinly sliced leeks along with the onions – they bring a lovely subtle sweetness. A pinch of nutmeg or a dash of cayenne pepper stirred into the cheese sauce can add a little warmth and complexity that’s just divine.
And the cheese! Oh, the cheese possibilities are endless. For an extra depth of flavor, try swapping out some of the cheddar for a good Monterey Jack, a smoked Gouda, or even a creamy Fontina. You can also play with the herbs. A little bit of fresh thyme or rosemary stirred into the sauce before baking adds a wonderful aroma. For a real treat, try stirring in some crispy cooked bacon bits or some sautéed mushrooms before you pour the sauce over the potatoes. These little twists can make your Dad’s Creamy & Cheesy Au Gratin Potatoes uniquely yours!
Serving Your Delicious Dad’s Creamy & Cheesy Au Gratin Potatoes
Now that you’ve got this bubbling, golden masterpiece, let’s talk about serving it up right! These Dad’s Creamy & Cheesy Au Gratin Potatoes are so rich and satisfying, they make the perfect partner for almost any main course. Think of them alongside a juicy roasted chicken, a tender pork loin, or even a grilled steak. They add that comforting, restaurant-quality touch to any meal.
Don’t forget that sprinkle of fresh chopped parsley right before you bring it to the table. It adds a pop of color and a hint of fresh flavor that cuts through all that creamy richness. It really makes the dish look as good as it tastes!
Storing and Reheating Your Dad’s Creamy & Cheesy Au Gratin Potatoes
Don’t you hate when delicious leftovers go to waste? I know I do! The good news is that Dad’s Creamy & Cheesy Au Gratin Potatoes reheat beautifully, so you can enjoy them again. Just make sure to store them properly. Once the dish has cooled down a bit, transfer any leftovers into an airtight container. You can keep them in the refrigerator for up to 5 days. They hold up so well!
When you’re ready for round two, you have a couple of options. For the best texture, I love reheating larger portions in the oven. Cover the dish with foil (this keeps them from drying out) and pop it into a 350°F oven. If they’re coming straight from the fridge, give them about 15 extra minutes to heat through. If you’re just grabbing a single serving, the microwave is super quick! Just reheat on medium power until everything is warm and bubbly again. Either way, you’ll be back to cheesy potato bliss in no time.
| Refrigerator Storage | Store in airtight containers for up to 5 days. |
| Oven Reheating | Cover and reheat at 350°F (175°C) until heated through, adding 15 minutes if reheating from chilled. |
| Microwave Reheating | Reheat individual portions on medium power until warm. |
Frequently Asked Questions about Dad’s Creamy & Cheesy Au Gratin Potatoes
Got questions about making these amazing potatoes? I’ve got answers! People always ask me about the nitty-gritty details, and I’m happy to share what I’ve learned over the years making this recipe for my family.
Can I use a different type of potato for Dad’s Creamy & Cheesy Au Gratin Potatoes?
While Yukon Golds are my absolute favorite for their creamy texture and how they hold up in this dish, you can use other potatoes. Russets work, but they can sometimes get a bit too soft and fall apart. Red potatoes are okay, but they have a waxier texture that might not be quite as ideal for that classic au gratin feel. The key is a potato that’s medium-starch and holds its shape while getting wonderfully tender. Just make sure to slice them evenly, no matter what kind you use!
My sauce seems too thin. What can I do to thicken it for Dad’s Creamy & Cheesy Au Gratin Potatoes?
Oh, that happens sometimes! If your sauce is looking a bit too runny after you’ve added the cheese, don’t worry. Just turn the heat down low and let it simmer gently for another few minutes, stirring constantly. The flour and cheese will continue to thicken it up. If it’s still too thin, you can make a quick slurry by mixing a teaspoon of cornstarch with a tablespoon of cold water, then whisking that into the sauce and letting it simmer for a minute. Just be careful not to make it *too* thick – you want it to coat the potatoes, not be a solid block!
Can I prepare Dad’s Creamy & Cheesy Au Gratin Potatoes ahead of time?
Yes, absolutely! This is a great make-ahead dish. You can assemble the whole thing – potatoes, onions, and sauce – cover it tightly, and pop it in the fridge for up to 3 days. When you’re ready to bake, just pull it out and add those extra 15 minutes to the initial covered baking time to make sure everything heats through properly. The top might not get quite as golden without the extra cheese added right before baking, so you can always sprinkle that on when you take the foil off.
How can I make Dad’s Creamy & Cheesy Au Gratin Potatoes extra cheesy?
My kind of question! To make these potatoes even cheesier, you can simply increase the amount of cheese you use. Add an extra ounce or two of cheddar or Gruyere into the sauce, or even sprinkle a little more on top before the final bake. You could also mix in some other great melting cheeses like Monterey Jack, Fontina, or even a bit of Colby. Some people even like to add a layer of cheese between the potato layers. Go wild – the more cheese, the better, right?
