What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients to deliver rich flavor and the perfect balance of creamy and crunchy. Most are pantry basics or easy to find at any grocery store.

• Potatoes: 3 pounds (about 1.4 kg) Yukon Gold potatoes, peeled and thinly sliced (Yukon Golds hold their shape well and have a buttery flavor)
• Bacon: 8 slices, thick-cut, cut into bite-sized pieces (I prefer Wright Brand for consistent quality)
• Gruyère cheese: 2 cups (about 200g), grated (look for aged Gruyère for that deep nuttiness)
• Heavy cream: 2 cups (480 ml) (adds richness; you can substitute half-and-half for a lighter version)
• Unsalted butter: 4 tablespoons (about 57g), room temperature (for the roux and finishing)
• All-purpose flour: 3 tablespoons (to thicken the sauce)
• Garlic: 2 cloves, minced (for a subtle aromatic boost)
• Onion: 1 small, finely chopped (adds sweetness)
• Salt: 1 teaspoon (adjust to taste)
• Black pepper: 1/2 teaspoon freshly ground
• Nutmeg: A pinch (optional, but it adds a warm, cozy undertone)
• Fresh thyme: 1 teaspoon leaves, chopped (optional, for a hint of earthiness)

If you want to swap out the potatoes, russets are fine but can be a bit fluffier. For a dairy-free twist, use a plant-based cream and dairy-free cheese, but the texture won’t be quite the same.

Equipment Needed

• Mandoline slicer or sharp knife: For slicing potatoes thin and even—important to ensure even cooking.
• Large skillet or frying pan: To crisp up bacon and sauté onions and garlic.
• Medium saucepan: For making the creamy cheese sauce.
• 9×13-inch (23×33 cm) baking dish: A standard casserole dish to bake the potatoes evenly.
• Mixing bowls: For prepping and combining ingredients.
• Whisk and wooden spoon: To stir the sauce and prevent lumps.
• Oven mitts and cooling rack: For safe handling and resting after baking.

If you don’t have a mandoline, use a very sharp knife and take your time slicing to about 1/8-inch thickness. For frying bacon, a cast iron skillet works wonders for crispness, but a nonstick pan is perfectly fine too. I usually keep a silicone spatula handy to scrape every last bit of flavor from the pan.

Preparation Method

1. Preheat your oven to 375°F (190°C). Grease your 9×13-inch baking dish with butter to prevent sticking.
2. Cook the bacon: Place bacon pieces in a large skillet over medium heat. Cook until crispy, about 8-10 minutes. Remove with a slotted spoon and drain on paper towels. Leave about 1 tablespoon of bacon fat in the pan for sautéing onions.
3. Sauté onions and garlic: Add chopped onion to the skillet with bacon fat. Cook over medium heat for 4-5 minutes until soft and translucent. Add minced garlic and cook for another 30 seconds until fragrant. Remove from heat.
4. Make the cheese sauce: In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes, stirring constantly to form a roux—this step is key to avoid flour taste. Slowly whisk in heavy cream, stirring to prevent lumps. Cook for 3-4 minutes until sauce thickens. Remove from heat and stir in grated Gruyère cheese until melted and smooth. Season with salt, pepper, and a pinch of nutmeg. Add fresh thyme if you like.
5. Layer the potatoes: Arrange a layer of thin potato slices in the baking dish, overlapping slightly. Sprinkle some of the sautéed onions, garlic, and half the bacon pieces over the potatoes. Pour a ladle of cheese sauce over this layer to coat evenly.
6. Repeat layering: Add another layer of potatoes, the remaining onions, bacon, and cheese sauce. Finish with a final layer of potatoes topped with remaining cheese sauce and a sprinkle of Gruyère for a golden crust.
7. Bake: Cover the dish tightly with foil and bake for 40 minutes. Then remove foil and bake uncovered for another 15-20 minutes until the top is bubbly and golden brown. A fork should slide easily into the potatoes.
8. Rest before serving: Let the dish cool for 10 minutes to set, making it easier to slice and serve.

Quick tip: If the top browns too fast, cover loosely with foil halfway through the uncovered baking. And if your sauce feels too thick before pouring, add a splash of cream to loosen it up.

Cooking Tips & Techniques

Getting creamy, tender scalloped potatoes with a golden crust is all about layering technique and careful timing. Here’s what I’ve learned:

• Slice potatoes evenly: Using a mandoline or very sharp knife ensures uniform cooking. Uneven slices can leave some crunchy edges or mushy centers.
• Don’t skip the roux: Cooking the butter and flour before adding cream prevents a raw flour taste and creates a smooth sauce.
• Cook bacon separately: This keeps it crispy and flavorful instead of soggy. Save a bit of bacon fat for sautéing onions for extra depth.
• Cover while baking: Trapping steam helps potatoes cook through without drying out the dish.
• Rest before serving: Patience here pays off. The dish firms up, making slicing neater and flavors more harmonious.

Once, I forgot to cover the dish and ended up with crunchy edges but raw centers—a rookie mistake that taught me to trust the foil. Also, don’t rush the cheese melting; Gruyère can seize if overheated, so off-heat mixing works best.

Variations & Adaptations

Feel free to make this recipe your own with these tweaks:

• Vegetarian: Omit the bacon and add sautéed mushrooms or caramelized onions for a savory twist.
• Different cheese: Swap Gruyère for sharp cheddar or a mix of Parmesan and mozzarella for a different flavor profile.
• Dairy-free: Use coconut cream and dairy-free cheese alternatives, keeping in mind the texture will be a bit different.
• Herbs: Try rosemary or sage instead of thyme to complement the potatoes and bacon.
• Make it gluten-free: Substitute all-purpose flour with cornstarch or gluten-free flour blends for the sauce.

One time, I added a layer of thinly sliced sweet potatoes for a touch of natural sweetness—it was surprisingly good! Also, if you prefer a lighter dish, reduce the cream by a third and add some low-sodium chicken broth instead.

Serving & Storage Suggestions

This Creamy Gruyere and Bacon Scalloped Potatoes Au Gratin is best served warm, straight from the oven, with a crisp green salad or roasted vegetables to balance the richness.

For a hearty meal, pair it with roasted meats like maple bourbon pork chops with caramelized apples or a simple grilled chicken. It’s also fantastic alongside loaded cream cheese stuffed mushrooms with bacon for a cozy dinner spread.

To store leftovers, cover tightly and refrigerate for up to 3 days. Reheat in the oven at 350°F (175°C) for 15-20 minutes to regain that crispy top and creamy inside. Avoid microwaving if possible, as it tends to make the potatoes soggy.

Interestingly, letting this dish rest overnight often deepens the flavors, making it even better the next day—perfect for meal prep or potluck contributions.
