Ingredients You’ll Need

Each ingredient in Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe plays a key role in balancing the rich, creamy texture with just enough flavor punch. Choosing the right potatoes and cheeses really helps elevate this dish from just “good” to “wow.” Here are some tips to set you up for success:

• Yukon Gold potatoes: These have the perfect starch content and buttery flavor, plus they hold their shape well during baking—making your layers look pretty and taste great.
• White or yellow onion: Adds a subtle sweetness and a bit of bite that melts down into the sauce for extra depth.
• Salted butter: Helps create that rich roux base for the sauce—don’t swap it out with margarine; butter’s creaminess is key here.
• All-purpose flour: This thickens the sauce nicely; I’ve also had success with whole wheat or gluten-free flour, so feel free to adapt.
• Unsweetened almond milk: You can use regular dairy milk if you prefer, but almond milk keeps it a little lighter without sacrificing creaminess.
• Sharp cheddar cheese: The star cheese in this recipe, providing that classic tangy, melty goodness that au gratin is known for.
• Garlic powder: Subtle but important — it adds a mild kick that complements the cheese beautifully.
• Salt and freshly ground black pepper: Season these carefully to balance the flavors just right without overpowering the dish.
• Gruyere cheese: Used as a topping here, it adds a lovely nutty flavor and browns to a perfect crust.
• Grated parmesan: Sprinkled on top for that punchy umami finish and extra crispness when baked.
• Fresh chopped parsley: For garnish—it brightens up the whole dish and adds a fresh, herby contrast to all that cheese.

Variations

I love how versatile Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe is, and honestly, you can tailor it to suit your taste or dietary needs pretty easily. Here are a few ways I’ve tweaked the recipe that you might want to try out too:

• Vegetarian twist: I sometimes add sautéed mushrooms or spinach layers between the potatoes to sneak in some greens without losing that cheesy comfort.
• Dairy-free version: Using dairy-free cheese and plant-based milk works surprisingly well, and I always recommend a smoky or sharp dairy-free cheddar for flavor.
• Spicy kick: Adding a pinch of cayenne or smoked paprika into the sauce gives it a warm, slightly spicy note that’s fantastic if you like a little heat.
• Herb infusion: Mixing fresh thyme or rosemary into the cheese sauce offers an earthy aroma that makes this dish feel even more special for fall or winter dinners.

How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe

Step 1: Prepare Your Potatoes and Onions

First things first, slice your Yukon Gold potatoes thinly—about 1/8-inch thick is ideal. I find using a mandoline slicer makes this step way faster and ensures even cooking, but a sharp knife works just fine if you’re careful. Slice your onion into thin rings or half-moons to layer with the potatoes. The key here is uniform slices so everything cooks evenly and you get that perfect creamy texture without any crunchy surprises.

Step 2: Make the Creamy Cheese Sauce

Melt the butter in a saucepan over medium heat. Once bubbly, whisk in the flour and stir constantly for about 1-2 minutes until it forms a smooth roux—this cooks out the raw flour taste. Slowly whisk in your almond milk (or dairy milk), continuing to whisk until the sauce thickens and becomes creamy, around 3-5 minutes. Then, remove from heat and stir in the shredded sharp cheddar, garlic powder, salt, and pepper. This sauce is the heart of Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe, so taste it and adjust the seasoning as needed before layering.

Step 3: Layer the Potatoes and Onions

In a buttered baking dish, start layering half the potato slices evenly. Sprinkle half the onions on top, then pour half the cheese sauce over everything. Repeat with the remaining potatoes, onions, and sauce. This layering ensures every bite is bursting with flavor and creaminess. Don’t rush this part—make sure layers are nice and even so it cooks uniformly.

Step 4: Add the Cheesy Topping and Bake

Mix the Gruyere and Parmesan cheeses and sprinkle evenly over the top layer. This combo melts beautifully and creates that irresistible golden crust typical of a great au gratin. Cover the dish with foil and bake at 350°F (175°C) for 45 minutes, then remove the foil and bake another 20 minutes to let the topping brown. You’ll know it’s done when the potatoes are tender and the top is bubbly and crisp. I usually poke through with a fork to check tenderness.

How to Serve Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe

Garnishes

I love sprinkling fresh chopped parsley right before serving—it adds a pop of color and a fresh herbal note that cuts through all that richness. Sometimes I add a little cracked black pepper on top too for extra bite. These small touches really elevate the dish.

Side Dishes

This creamy au gratin pairs wonderfully with roast chicken, pork tenderloin, or even a simple green salad if you want a lighter meal. I often serve it alongside steamed green beans or roasted Brussels sprouts to balance out the richness with some fresh veggies. It’s really a star that complements many meals.

Creative Ways to Present

For special occasions, I’ve tried making individual ramekins or mini cast-iron skillets with this recipe. It’s such a crowd-pleaser and looks impressive when served this way. You can also layer thin slices of cooked ham or cooked bacon between the potatoes for an extra hearty presentation that guests love.

Make Ahead and Storage

Storing Leftovers

I store leftover au gratin in an airtight container in the fridge for up to 3 days. When I reheat it, I find the texture stays creamy without getting dry, especially if you cover with foil to keep moisture locked in. Just be sure to cool it completely before storing.

Freezing

I’ve frozen this dish a couple of times with good results. Just let it cool fully, portion it into freezer-safe containers, and freeze for up to 2 months. When ready to eat, thaw overnight in the fridge and bake at 350°F until heated through and bubbly again. The cheese sauce may separate a little but stirring gently before reheating fixes that.

Reheating

For reheating leftovers, I usually cover the dish with foil and bake at 325°F until warmed through—about 20-25 minutes. Alternatively, small portions reheat well in the microwave, but the oven method keeps the cheesy crust intact and delicious.
