Ingredients for betty crocker au gratin potatoes chicken

These premium ingredients transform simple potatoes and chicken into Betty Crocker’s signature crispy, creamy masterpiece.

The chicken and potatoes are the foundation—bone-in, skin-on thighs ensure juicy results, while Russet potatoes (not waxy) hold their shape during baking. For the cheese, Gruyère delivers that signature nutty depth, but Comté or Emmental work beautifully too. Shallots add complexity without overpowering—substitute with 1 small yellow onion if unavailable. The Panko breadcrumbs are non-negotiable for that signature crunch; Japanese panko works best, but plain breadcrumbs in a pinch will suffice. Diamond Crystal kosher salt is preferred for its clean flavor, but Morton’s will work if that’s what you have.

No Gruyère? Sharp cheddar or Gouda bring a different but equally satisfying flavor. Heavy cream can be swapped for half-and-half for a lighter texture, though the sauce won’t be as rich. Dijon mustard is essential for that tangy brightness—whole-grain mustard works in a pinch, but reduce to 1 tsp to avoid bitterness. The roux (butter + flour) is critical for thickening; don’t skip the cold butter or it won’t emulsify properly. For extra flavor, toast the flour in the butter for 1-2 minutes before adding liquid. Fresh parsley garnishes beautifully, but dried parsley at one-third the amount works if you’re in a hurry.

Prep the potatoes and chicken ahead—they keep well in the fridge for up to 24 hours before baking. The sauce can be made a day ahead and reheated gently. Store leftovers in an airtight container for up to 4 days, though the crispy top loses its texture after 2 days. For freezing, bake the dish, let it cool completely, then freeze in a single layer before transferring to a container. Reheat covered at 350°F for 20 minutes—add a splash of milk to restore creaminess if needed. This dish reheats beautifully, making it perfect for meal prep.

Step-by-step instructions for Betty Crocker au gratin potatoes with chicken

Master this one-pan technique for golden, crispy layers and velvety cheese sauce.

Preheat your oven to 400°F. Pat the 1.5 lb chicken thighs dry with paper towels and season both sides generously with 1 tsp Diamond Crystal kosher salt and ¼ tsp freshly ground black pepper. In a large oven-safe skillet, heat 2 tbsp unsalted butter over medium-high heat until foaming. Add the chicken and sear for 5-6 minutes per side until golden brown and cooked through to 165°F internally. Remove the chicken and set aside on a plate.

While the chicken cooks, peel and thinly slice the 3 lb russet potatoes into ⅛-inch thick rounds. You should have about 6 cups of slices. Toss the potato slices with ½ tsp Diamond Crystal kosher salt and ¼ tsp freshly ground black pepper to season evenly. Arrange the potato slices in overlapping rows in the same skillet, slightly overlapping each layer. Pour ½ cup warm whole milk over the potatoes and let them sit for 5 minutes to begin softening.

In a medium saucepan, melt the remaining 2 tbsp unsalted butter over medium heat. Add the 3 minced shallots and 4 minced garlic cloves, cooking for 2-3 minutes until softened and fragrant. Stir in the 0.25 cup all-purpose flour and cook for 1 minute to create a roux, stirring constantly to prevent burning.

Gradually whisk in the 1.5 cups heavy cream and 0.5 cup warm whole milk, stirring continuously until the mixture thickens to a velvety consistency. Remove from heat and stir in the 1 tbsp Dijon mustard, 1.5 cups shredded Gruyère cheese, and 0.5 cup freshly grated Parmesan cheese until fully melted and smooth. Season with an additional ½ tsp Diamond Crystal kosher salt and ¼ tsp freshly ground black pepper.

Return the skillet to the oven. Pour the cheese sauce evenly over the potatoes, ensuring each slice is fully coated. The sauce should bubble gently. Sprinkle the 0.5 cup panko breadcrumbs evenly over the top, pressing down lightly to create a crispy crust. Return the skillet to the oven and bake for 30-35 minutes until the top is golden brown and the potatoes are tender when pierced with a fork.

Here's the key: Watch for the edges to turn golden and the top to develop a crispy, breadcrumb crust. If the top browns too quickly, tent loosely with aluminum foil to prevent burning while the center finishes cooking. The potatoes should be fork-tender with no resistance.

Remove the au gratin from the oven and let it rest for 5-10 minutes before serving. This resting period allows the layers to set slightly and makes slicing easier. Using a large spatula, carefully transfer the au gratin to a serving platter, arranging the chicken thighs on top of the potatoes. Garnish with 0.25 cup chopped fresh parsley for a pop of color and freshness.

The perfect slice should reveal creamy, melted cheese layers with tender potatoes and crispy, golden edges. Serve immediately with a simple green salad or steamed vegetables to complement the rich flavors. The combination of crispy top, creamy layers, and tender chicken creates a harmonious one-pan masterpiece that delivers on both texture and flavor promises.

Best sauces and condiments for these flavors

Classic Cheese Sauce

The heart of this dish is the creamy cheese sauce, where Gruyère and Parmesan melt into a velvety blanket over the potatoes. I start by making a roux with 2 tbsp cold butter and ¼ cup flour, cooking it until golden for that nutty depth.

The 1.5 cups heavy cream and ½ cup warm milk create a silky texture, while 1 tbsp Dijon mustard adds a tangy brightness. For extra richness, I sometimes stir in 1 tbsp sour cream at the end—it keeps the sauce luscious without curdling. 🧀

Garlic-Infused Butter

Before assembling, I enhance the flavor by infusing 2 tbsp butter with 3 minced shallots and 4 minced garlic cloves until fragrant. This aromatic base elevates the entire dish, especially when melted into the sauce.

For a deeper flavor, I toast the shallots and garlic for 2-3 extra minutes until they turn golden. If you’re short on time, 1 tsp garlic powder works, but fresh is always better. 🧄

Crispy Top Secrets

The panko breadcrumb topping is non-negotiable for that golden, crispy finish. I press it firmly into the sauce before baking to create a sturdy crust. For extra crunch, I mix in 1 tbsp melted butter with the breadcrumbs.

If you don’t have panko, crushed cornflakes or fine breadcrumbs work, but they won’t be as crispy. A sprinkle of Paprika adds color and a subtle smoky note. 🍞

Herb Garnishes

Fresh herbs brighten up the dish and add a pop of color. I always finish with ¼ cup chopped parsley, but chives or thyme work beautifully too. For a bolder flavor, I mix in 1 tsp fresh thyme leaves directly into the sauce before baking.

If using dried herbs, reduce to ⅓ the amount—they’re more concentrated. A pinch of smoked paprika over the top adds warmth without overpowering. 🌿

Sour Cream Swirl

For a restaurant-quality touch, I swirl 2 tbsp sour cream into the sauce before baking. It adds a subtle tang that balances the richness. To create the swirl, drop spoonfuls of sour cream onto the sauce, then gently drag a knife through the center.

This technique keeps the sauce creamy and adds visual appeal. If you prefer a smoother texture, blend the sour cream into the sauce instead. 🥛

Mustard Kick

The Dijon mustard in the sauce isn’t just for flavor—it cuts through the richness and adds complexity. I use 1 tbsp, but for a sharper taste, increase to 1.5 tbsp. If you don’t have Dijon, whole-grain mustard works, but reduce to 1 tsp to avoid bitterness.

For a smoky twist, I sometimes add ½ tsp smoked paprika to the sauce before baking. 🌶️
