Ingredients for betty crocker au gratin potatoes chicken
Essential ingredients for a restaurant-quality one-pan meal that balances crispy chicken and creamy au gratin potatoes.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 lbs | Thinly sliced, uniform thickness |
| Boneless Chicken Thighs 🍗 | 1 ½ lbs | Skin-on, cut into even pieces |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Whole Milk 🥛 | 1 cup | Room temperature preferred |
| Shredded Gruyère Cheese 🧀 | 1 ½ cups | Freshly shredded, not pre-shredded |
| Shredded Sharp Cheddar 🧀 | 1 cup | Medium sharpness preferred |
| Garlic Cloves 🧄 | 6 cloves | Minced, for even distribution |
| Yellow Onion 🧅 | 1 whole | Thinly sliced, white or yellow |
| All-Purpose Flour 🌾 | 2 tbsp | For chicken coating |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Unsalted Butter 🧈 | 2 tbsp | For pan-searing chicken |
| Olive Oil 🫒 | 2 tbsp | For even cooking |
The potatoes are the foundation here. Yukon Golds (or Russets) work best—their buttery texture holds up to the creamy sauce. Thinly slice them uniformly for even cooking, about 1/8-inch thick. For the chicken, thighs with skin stay juicier than breasts. Most grocery stores carry pre-sliced potatoes, but if not, invest in a mandoline for perfect slices. The cheese matters too—freshly shredded Gruyère melts smoother than pre-shredded, and sharp cheddar adds that classic tang. If you're short on time, Trader Joe's carries pre-shredded Gruyère that's surprisingly good.
No heavy cream? Half-and-half plus 1 tbsp butter works in a pinch, though the texture won't be quite as luscious. Short on Gruyère? Swiss or Emmental melt beautifully. For the chicken coating, all-purpose flour is standard, but cornstarch creates an extra-crispy crust. The garlic and onion can be swapped for 1 tbsp garlic powder and 1 tbsp onion powder if fresh isn't available. For the thyme, 1 tbsp fresh is ideal but 1 tsp dried works if that's what you've got. The butter and olive oil combo ensures the chicken gets both richness and crispiness—don't skip the olive oil, even though it's not traditional.
This dish reheats beautifully, though the texture changes slightly. For best results, reheat covered at 350°F for 15 minutes to maintain creaminess. Leftovers keep for 3-4 days in the fridge, though I rarely have any. The cheese topping can get rubbery if stored too long, so cover it tightly with foil before refrigerating. For meal prep, assemble the dish in the pan but bake it only halfway (about 20 minutes), then refrigerate. Finish baking when ready to serve—this keeps the potatoes from getting soggy.

Step-by-step instructions for creamy chicken and potato au gratin
This one-pan method delivers tender chicken, perfectly cooked potatoes, and a rich, bubbling cheese topping.
Prepare and Sear the Chicken
Pat the 1.5 lbs boneless chicken thighs dry with paper towels. Season both sides generously with 1.5 tsp salt, 1 tsp black pepper, and 1 tsp dried thyme. In a large oven-safe skillet, heat 2 tbsp olive oil and 2 tbsp unsalted butter over medium-high heat until the butter foams. Add the chicken and cook for 4-5 minutes per side until golden brown and cooked through to 165°F internally.
Remove the chicken from the skillet and set aside on a plate. The residual heat will keep it warm while you prepare the potato mixture. If the chicken releases easily from the pan, it's ready. If it sticks, let it cook a little longer before gently lifting with a spatula.
Build the Potato and Cream Base
In the same skillet, reduce heat to medium and add the 1 whole yellow onion and 6 cloves garlic cloves, minced. Sauté for 3-4 minutes until the onion softens and the garlic becomes fragrant. Sprinkle in the 2 tbsp all-purpose flour and stir for 1 minute to cook off the raw flour taste.
Pour in the 1 cup whole milk and 1 cup heavy cream, stirring constantly to prevent lumps from forming. Bring the mixture to a gentle simmer, then reduce heat to low. Add the 2 lbs thinly sliced yukon gold potatoes, stirring to coat them evenly in the creamy mixture. Let it simmer for 5-7 minutes until the potatoes begin to soften slightly.
Layer and Assemble the Au Gratin
Return the seared chicken to the skillet, arranging the pieces over the potatoes. Sprinkle 1 cup shredded sharp cheddar and 1.5 cups shredded gruyère cheese evenly over the top. The cheese should cover the potatoes completely, with a generous layer on top for that classic golden crust.
Transfer the skillet to a preheated 375°F oven and bake for 25-30 minutes, until the cheese is deep golden brown and bubbling vigorously. The edges should pull away from the pan slightly, indicating the cheese has melted and formed a crispy topping. If the cheese browns too quickly, tent loosely with foil to prevent burning.
Rest and Serve
Remove the skillet from the oven and let the au gratin rest for 5-10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice and serve. The internal temperature of the potatoes should reach 210°F, ensuring they're fully tender with no resistance when pierced with a fork.
Serve immediately in individual portions, ensuring each serving includes both chicken and potatoes. The creamy sauce should be rich and velvety, with a crispy, cheesy crust on top. Pair with a simple green salad or steamed vegetables for a complete meal.
Pro Tips For Making Betty Crocker Au Gratin Potatoes Chicken
- PARBOIL POTATOES FIRST: I learned this the hard way—skipping the parboil makes your Yukon Golds turn to mush under all that cream. Cut them into even ¼-inch slices, boil in salted water for exactly 5 minutes, then drain and cool. This keeps them firm enough to hold their shape while soaking up the cheesy sauce.
- SEAR CHICKEN UNTIL BROWNED: Don’t just toss those chicken thighs into the oven raw—sear them first in a hot skillet with a little oil until golden on both sides. This locks in moisture and adds depth of flavor that no amount of cream or cheese can replicate. (Yes, even if you’re impatient like me.)
- SKIP THE PRE-SHREDDED CHEESE: That pre-shredded Gruyère in the bag is coated with anti-caking agents that make your au gratin turn grainy. Buy a block, shred it yourself with a box grater, and pack it tightly into the dish—it melts smoother and browns better. (Your future self will thank you.)
- BAKE COVERED THEN UNCOVERED: Start the dish covered with foil for the first 45 minutes to let the potatoes soak up the cream without drying out. Then uncover for the last 10-15 minutes—this gives the top that golden, crispy crust while keeping the inside creamy. (Does it look weird? Yes. Does it work? Every single time.)
Make-ahead tips for this recipe
Prep Ahead Strategy
Assemble the entire dish in the oven-safe skillet up to 24 hours in advance—this is the secret to stress-free weeknight dinners. Store the assembled (but unbaked) skillet in the fridge, covered with plastic wrap.
When ready to cook, simply bake at 375°F for 35-40 minutes, adding 5-10 extra minutes to account for the cold start. The potatoes will still achieve that creamy perfection without drying out. 📅
Chicken Prep Shortcut
Save time by pre-searing the chicken 1-2 days ahead and storing it in an airtight container. When ready to assemble, simply reheat the chicken in the skillet over medium heat for 2-3 minutes before adding the potato mixture.
This maintains crispiness while keeping the process efficient. I keep a batch of pre-seared chicken thighs in the freezer for quick meals—just thaw overnight in the fridge. 🍗
Cheese Layer Hack
For a foolproof golden crust, mix 2 tbsp breadcrumbs into the cheese before sprinkling on top. This creates a crispy, textured layer that holds up better when reheated. Another trick: press parchment paper directly onto the melted cheese before it sets—it peels away like a perfect slice every time.
I use this method when prepping for gatherings. ✨
Baking Timeline
If baking ahead for a party, cook the dish halfway (about 20 minutes at 375°F), then refrigerate. Finish baking when guests arrive—this ensures the cheese stays bubbly and golden.
For large groups, use two skillets to maintain even cooking. The potatoes should reach 210°F internal temperature when fully cooked. 🕒
Reheating Leftovers
Reheat individual portions in the microwave for 2-3 minutes on 50% power, covered with a damp paper towel. For oven reheating, cover with foil and bake at 350°F for 15 minutes—this preserves the creamy texture better than microwave methods.
I always reheat leftovers with a splash of milk to restore richness. 🔥
Freezer-Friendly Assembly
For long-term storage, assemble the dish and bake for 15 minutes before cooling completely. Store in an airtight container for up to 3 months. To serve, thaw overnight in the fridge, then bake at 375°F for 25 minutes.
The texture remains surprisingly close to fresh—just add a sprinkle of extra cheese when reheating for that restaurant-quality finish. ❄️
Nutrition facts
Frequently asked questions
Can I use chicken breasts instead of thighs?
Chicken breasts work, but thighs are ideal for this recipe. The thighs stay juicier and more tender during the long baking time. If using breasts, cut them into 1-inch pieces and bake them separately for 12-15 minutes at 400°F before adding to the au gratin. This prevents dryness while keeping the crispy skin.
How do I fix soggy potatoes in au gratin?
Soggy potatoes usually happen from overcooking or too much liquid. The fix: bake at 375°F for 20 minutes, then uncover and broil for 3-5 minutes to crisp the top. For future batches, make sure to:
- Use 1/8-inch thick slices (not too thin)
- Drain excess liquid after simmering the potatoes
- Add 1/4 cup breadcrumbs to the cheese layer for extra texture
Can I make this dish ahead of time?
Assemble the dish (unbaked) up to 24 hours ahead and refrigerate. When ready to cook, bake at 375°F for 35-40 minutes. For parties, bake halfway (20 minutes), refrigerate, then finish baking when guests arrive. The potatoes stay creamy and the cheese stays bubbly.
What's the best cheese substitute if I don't have Gruyère?
Gruyère is key for that classic flavor, but you can use Swiss or Emmental for a similar melt. For extra richness, mix 1 cup Gruyère substitute + 1/2 cup sharp cheddar. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. If you're dairy-free, use nutritional yeast + vegan cheese blend for a cheesy flavor.
Why did my cheese not brown properly?
Uneven browning usually means the oven wasn't hot enough or the dish wasn't uncovered. Try this:
- Preheat oven to 400°F for the last 5 minutes of baking
- Uncover the dish for the final 3-5 minutes to let the cheese crisp
- Broil for 1-2 minutes at the very end (watch closely!)
- Make sure your skillet is oven-safe and fits properly in your oven
