Section: Perfect Side Dishes to Complete Any Meal

Thin-sliced Yukon gold potatoes are layered with crispy bacon, sweet caramelized onions, and a homemade cream sauce, then finished with a blend of sharp cheddar and nutty Gruyere. Baked until bubbly with a golden top, each forkful delivers buttery potato, melty cheese, and savory depth from slow-cooked onions and bacon. This comforting classic shines at holiday tables or family gatherings, especially when served alongside simple proteins. Tip: let it rest for clean slices and don't rush the caramelization.

This loaded scalloped potatoes recipe is what I reach for when family and friends expect something special at the table. The layers of thin sliced potatoes bake up in a creamy made from scratch sauce filled with crispy bacon, ribbons of sweet caramelized onion, and a mix of melty cheeses. It is comfort food at its best and feels right at home next to a simple roast for Sunday dinner or the holiday ham at Thanksgiving. Over the years this has become my trusted side for every gathering where I want empty plates and happy faces.

I first made this by pure necessity when I was out of inspiration and groceries. The reaction from my family (and later my mother in law) made it clear I was onto something. Every time someone new tries these potatoes there is a moment of silence at the table followed by someone asking for the recipe.

Ingredients

  • Yukon Gold potatoes: create the creamiest texture and hold their shape during baking. Use firm potatoes without sprouting eyes for best results
  • Caramelized onions: are worth the patience for deep sweet flavor. Choose yellow onions that feel heavy and tight skinned
  • Crisp bacon: adds smoky crunch. Go for thick slices and cook until crumbly so it contrasts the tender potatoes
  • Cheddar and Gruyere mix: balances tang and nuttiness. Select blocks to grate yourself for smooth melting
  • Homemade cream sauce: brings everything together. Whole milk and fresh butter give that luscious mouthfeel packaged shortcuts just cannot match

Instructions

Slicing Potatoes Evenly:
Use a mandoline if possible for uniform thin slices. It speeds up prep and ensures every piece bakes through evenly. Watch your fingertips especially when moving quickly
Cooking Onions Slowly:
Start with a heavy pan over low heat and stir the onions often so they soften very gradually. That extended caramelization time draws out the natural sugars and gives the final dish its signature complex flavor
Building The Roux Properly:
Melt butter then whisk in flour until you smell a toasty nutty aroma this prevents lumps. Warm your milk slightly before slowly adding and whisking constantly until you have a silky pourable sauce
Layering Everything:
Alternate potatoes onions bacon and cheese building up in a snug baking dish. Pour sauce over each layer and finish with a generous final sprinkle of cheese for the perfect browned crust
Resting After Baking:
Take the pan out when bubbling and golden and let it sit for at least fifteen minutes. This not only safeguards mouths from lava hot cheese but lets everything firm up so you can cut tall neat slices

My secret favorite part is the interplay of caramelized onions and Gruyere. That moment when the aroma hits as you open the oven brings back the memory of my husband sneaking forkfuls straight from the pan before dinner. Sometimes I double the onions just so I am sure every slice is loaded.

Serving Ideas

Pairs perfectly with roast chicken steak glazed ham or even as the centerpiece of a brunch spread with a bright salad. For holidays I assemble the day before and bake just before guests arrive which actually enhances the flavor after a slow rest in the fridge. A sprinkle of fresh thyme or chive before serving makes it look even more inviting and adds a little herbal lift.

Changing It Up

Ham or pancetta stand in well when bacon is not on hand and bring their own smoky punch. Roasted garlic mashed into the sauce adds an unexpected depth with little extra effort. Mix in a few sweet potatoes for flavor and color contrast especially in the fall.

Real Talk

Let us be honest these potatoes are a project and best reserved for days when sharing a special meal matters more than saving time. The results are so rich and rewarding that all the effort pays off the minute you see the golden bubbling pan on the table and your family grins in anticipation.

Frequently Asked Questions

Can I Make These Potatoes Ahead Of Time Assemble up to a day in advance and refrigerate covered. Add extra baking time since it will start cold. What Kind Of Potatoes Work Best Yukon Golds are first choice with russets as a good backup. Avoid red potatoes since they stay too firm. Can I Freeze It Freeze the assembled uncooked dish for later and bake after thawing in the fridge overnight.

Success Stories

This recipe has now been claimed as my official job at every extended family gathering. There is no better compliment than seeing someone return for a second helping especially when they usually claim not to like potatoes. Over the years friends who thought scalloped potatoes were bland have raved about this loaded version with its crave worthy cheese crust and rich filling.

Freezer Meal Conversion

To freeze for later assemble but do not bake. Wrap tightly and label for up to two months in the freezer. Thaw overnight in the fridge. Bake as usual but expect to add extra time covered before uncovering to brown the top. The texture may change slightly but reheated leftovers are still delicious.

Storage Tips

Leftovers keep well in the fridge for up to four days. Reheat gently covered with foil in the oven to restore the creamy texture. Microwaving works but the potatoes can sometimes get mushy so I use the oven when possible.

Ingredient Substitutions

Fontina and Gouda both melt beautifully if you do not have Gruyere. Regular bacon can be swapped for turkey bacon for a lighter dish. I have even used finely chopped cooked mushrooms for a vegetarian version and the umami stands in nicely.

Seasonal Adaptations

In spring add a handful of fresh peas or chopped scallion greens for color and freshness. For fall use sweet potatoes or butternut squash in place of some potatoes. Winter calls for doubling the caramelized onions and serving it piping hot.

Yes, assemble and refrigerate up to a day before baking. Add 15 minutes to the baking time if cooking from cold.

Yukon Gold potatoes offer a buttery flavor and smooth texture. Russets are also good, but avoid waxy types like red potatoes.

A blend of sharp cheddar and Gruyere adds depth, but Gouda, fontina, or Monterey Jack also work well. Avoid pre-shredded cheese for a smooth sauce.

What You’ll Need

→ Vegetables

01 3 pounds Yukon Gold potatoes, peeled and sliced 1/8 inch thick
02 2 large yellow onions, thinly sliced

→ Proteins

03 8 slices thick-cut bacon, cooked until crisp and crumbled

→ Dairy

04 1 1/2 cups shredded sharp cheddar cheese
05 1 cup shredded Gruyère cheese
06 3 cups whole milk
07 6 tablespoons unsalted butter

→ Pantry

08 1/3 cup all-purpose flour
09 2 teaspoons kosher salt, divided
10 1/2 teaspoon freshly ground black pepper, divided
11 1/4 teaspoon ground nutmeg

→ Optional Garnish

12 2 teaspoons chopped fresh thyme (for serving, optional)

Step-by-Step Guide

Step 01

Melt 2 tablespoons unsalted butter in a large skillet over medium-low heat. Add sliced onions and 1/2 teaspoon of salt. Cook, stirring occasionally, until onions are caramelized and deep golden, 30 to 40 minutes. Remove from heat and set aside.

Step 02

Place bacon in a cold large skillet. Set over medium heat and cook until crisp, turning as needed, about 8-10 minutes. Transfer to a paper towel–lined plate, cool, and crumble. Reserve 1 tablespoon bacon fat for later use.

Step 03

In a heavy saucepan, melt the remaining 4 tablespoons butter over medium heat. Add flour and whisk constantly to form a pale roux, about 2 minutes. Gradually add milk, whisking constantly to prevent lumps. Season with remaining salt, pepper, and nutmeg. Reduce heat to low and cook, stirring often, until thickened and smooth, 5 to 7 minutes. Remove from heat and fold in half of the cheddar and Gruyère until melted.

Step 04

Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish. Layer one third of potatoes in an even layer, season lightly with salt and pepper, and top with one third each of caramelized onions, crumbled bacon, and remaining cheeses. Repeat for two more layers. Strain and pour warm sauce evenly over the final layer. Tap dish gently to allow sauce to settle between layers.

Step 05

Cover baking dish tightly with aluminum foil. Bake for 45 minutes. Remove foil and continue baking until potatoes are tender and the top is golden and bubbling, about 25–30 minutes more.

Step 06

Let casserole rest for at least 15 minutes before serving to allow sauce to set. Sprinkle with fresh thyme if desired before serving.

Handy Tips

  1. For the creamiest texture, ensure the potatoes are sliced evenly; using a mandoline is highly recommended for uniform cooking.
  2. Assembling the dish ahead of time and refrigerating unbaked enhances flavor; simply add 15 minutes to baking time if starting from cold.
