Ingredients for betty crocker au gratin potatoes chicken
Sixteen ingredients for a showstopping one-dish meal that's all about comfort and crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 3 lb | Thinly sliced, peeled and parboiled |
| Boneless Chicken Thighs 🍗 | 1 ½ lb | Skin-on preferred for crispiness |
| Heavy Cream 🥛 | 2 cups | Full-fat for richest texture |
| Shredded Cheddar Cheese 🧀 | 3 cups | Sharp cheddar preferred |
| Celery Stalks 🧅 | 1 bunch | Thinly sliced for crown |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | ½ cup | For velvety sauce |
| Garlic Cloves 🧄 | 4 cloves | Minced for seasoning |
| Dried Thyme 🌿 | 1 tbsp | Or 1 tbsp fresh thyme |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | 1 tsp | For extra flavor |
| Breadcrumbs 🍞 | ½ cup | Panko for extra crunch |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated |
The potatoes are the heart of this dish, so Yukon Golds are your best bet—they're buttery and hold their shape. Grab a 3-pound bag from the grocery store, or Costco if you're feeding a crowd. Thinly slicing them (about 1/8-inch thick) is key—use a mandoline if you're not confident with a knife. I always parboil mine for 5 minutes first to soften the edges slightly, which keeps them from turning mushy later. For the chicken, thighs with skin stay juicier than breasts, and the skin adds extra crispiness when baked. Season them generously before they hit the oven—don't skimp on the salt and pepper here.
No Yukon Golds? Russets or red potatoes work in a pinch, but they won't be as creamy. Short on heavy cream? Half-and-half plus 2 tbsp butter gives you similar richness. The celery crown is where this dish gets its signature crunch—if you're out of celery, thinly sliced green onions or shallots add a nice bite. For the cheddar, sharp cheddar melts best, but monterey jack works too if that's what you've got. The breadcrumbs? Panko is ideal, but regular breadcrumbs toasted in the oven first give you better texture. And if you're watching calories, you can swap half the heavy cream for low-fat milk—it'll still taste amazing.
This dish reheats beautifully—just cover it with foil and warm in the oven for 15 minutes. Leftovers keep for 3-4 days in the fridge, but honestly, it's even better the next day once everything melds together. For make-ahead prep, assemble the dish (without baking) up to 24 hours ahead—just refrigerate it covered, then bake straight from the fridge. The celery crown will stay crisp if you add it fresh right before the final 10 minutes of baking. Portion into individual containers for easy lunches—just pop them in the microwave for 2 minutes, and you've got a comforting meal in seconds.

Step-by-step instructions for one-dish comfort with crispy celery crown
Here's how to build a hearty, golden dish that delivers crispy edges and creamy layers—every bite perfect.
Prepare the Chicken and Potato Base
Preheat your oven to 375°F. Pat the 1.5 lb boneless chicken thighs dry with paper towels and season generously with 1.5 tsp salt, 0.5 tsp black pepper, and 1 tsp garlic powder. Place them in a skillet over medium heat and cook for 5-6 minutes per side until golden brown and cooked through. Remove and set aside.
While the chicken cooks, peel and thinly slice the 3 lb Yukon Gold potatoes into ¼-inch rounds. Parboil them in salted water for 5 minutes, then drain and return to the pot. Stir in the 0.5 cup melted butter and 1 tbsp dried thyme until evenly coated. This step ensures your potatoes stay tender while absorbing rich flavor.
Build the Creamy Cheese Layer
In a medium bowl, whisk together the 2 cups heavy cream, 0.5 cup all-purpose flour, 1.5 tsp salt, 0.5 tsp black pepper, and 1 tsp garlic powder until smooth. This creates a velvety sauce that will bind everything together. Gently fold in the 3 cups shredded cheddar cheese until fully combined—no lumps should remain.
Transfer half of the potato mixture to a greased 9x13-inch baking dish. Pour the creamy cheese mixture evenly over the potatoes, then add the cooked chicken thighs on top. This layering ensures the chicken stays moist while the cheese melts into a luscious sauce.
Create the Crispy Celery Crown
Thinly slice the 1 bunch celery stalks into ¼-inch rounds. In a small bowl, toss the celery with 0.5 cup breadcrumbs, 0.25 cup freshly grated parmesan cheese, 4 minced garlic cloves, 0.5 tsp black pepper, and 1 tsp garlic powder. Spread this mixture evenly over the top of the baking dish, pressing down gently to create an even crown.
Bake uncovered for 45-50 minutes until the top is deep golden brown and the edges are bubbling. The celery crown should be crispy enough to hold its shape when lifted—this is your signal it's ready. If it browns too quickly, tent loosely with foil for the last 10 minutes to prevent over-browning.
Rest and Serve with Confidence
Remove the dish from the oven and let it rest for 10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice without losing the crispy crown or creamy filling. The potatoes should be tender but still hold their shape, and the cheese sauce should be thick and luxurious.
Garnish with extra freshly grated parmesan cheese and freshly cracked black pepper for a finishing touch. Serve immediately with a side of steamed green beans or a crisp salad—each forkful delivers the perfect balance of crispy, creamy, and savory comfort.
Pro Tips For Making Betty Crocker Au Gratin Potatoes Chicken
- PRE-COOK THE CHICKEN: I learned this the hard way—raw chicken thighs in a creamy casserole turn rubbery instead of tender. Poach them in simmering water for 12-15 minutes first, then shred. The meat stays juicy and absorbs flavors better than if you try to cook it straight from frozen or raw in the oven.
- SLICE POTATOES THIN: The recipe might call for "thick slices," but I’ve found ⅛-inch cuts crisp up faster and guarantee that golden crust. Use a mandoline if you’re impatient—it’s worth the rental fee for this dish. Thicker slices? You’ll end up with a sad, soggy middle.
- SALT THE CREAM: Skip this and your au gratin will taste bland, no matter how much cheese you add. Mix ½ teaspoon salt into the heavy cream before pouring it over the potatoes—it seasons the whole dish evenly. I used to just season the cheese, and the flavor felt one-dimensional.
- BAKE COVERED THEN UNCOVERED: Start with foil on to melt the cheese and cook the chicken gently, but switch to uncovered for the last 10 minutes. This gives you that perfect golden top without a steamy, limp mess. I know it’s tempting to leave it covered, but trust me—crust matters here.
Storing and reheating your betty crocker au gratin potatoes chicken
Oven Reheating Perfection
For the best texture, reheat your au gratin potatoes and chicken in the oven at 350°F for 15-20 minutes. Cover the dish tightly with aluminum foil to trap moisture—this prevents the celery crown from drying out while gently warming the creamy layers.
I like to add 2 tablespoons of heavy cream before reheating to restore richness. The key is patience: low heat ensures the chicken stays tender and the potatoes don't turn rubbery. 🔥
Microwave Shortcuts
When time is tight, use the microwave for individual portions. Cover with a damp paper towel and heat on 70% power for 2-3 minutes, then stir and continue in 30-second intervals until reaching 165°F internal temperature.
Add 1 tablespoon of milk or broth to prevent dryness—this trick works especially well for reheating leftovers. For best results, serve immediately after microwaving.
Freezer Storage Tips
This dish freezes beautifully for up to 3 months! Let it cool completely, then wrap tightly in plastic wrap followed by aluminum foil to prevent freezer burn. I recommend portioning into individual quart-sized freezer bags for easy reheating.
When ready to eat, thaw overnight in the fridge before reheating in the oven. The celery crown will lose some crispness but regains texture beautifully when warmed through. ❄️
Make-Ahead Baking Hack
Assemble the entire dish (except the celery crown) up to 24 hours ahead and refrigerate uncovered. When ready to bake, add the celery crown fresh and bake straight from the fridge—this prevents sogginess. The cold start helps create that perfect crispy top.
I often do this for holiday meals when I need to juggle multiple dishes. Just add 5-10 extra minutes to the baking time if coming from cold.
Crispy Crown Revival
If your celery crown loses crispness during storage, revive it by broiling for 2-3 minutes at the end of reheating. Spritz with a tiny bit of olive oil and sprinkle with extra breadcrumbs before broiling for maximum crunch.
This works especially well for restaurant-style presentation when serving to guests. The broiler's direct heat brings back that satisfying crunch in seconds. 💫
Nutrition facts
Frequently asked questions
Can I substitute chicken breasts for thighs in this recipe?
Chicken breasts will work, but thighs stay juicier and more flavorful. If using breasts, pound them to an even thickness and bake at 350°F for 15 minutes before adding to the dish. For extra moisture, brine them for 30 minutes before cooking.
Why does my celery crown turn soggy instead of crispy?
Soggy crowns happen when moisture escapes during baking. Press the celery firmly into the breadcrumb mixture and bake uncovered for the full 45-50 minutes. If needed, broil for 2-3 minutes at the end to restore crispness. Adding an extra 1/4 cup breadcrumbs helps too.
Can I make this dish ahead of time?
Assemble everything (except the celery crown) up to 24 hours ahead and refrigerate uncovered. Add the crown fresh before baking. For make-ahead baking, let the dish sit at room temperature for 30 minutes before baking if coming straight from the fridge.
What's the best way to reheat leftovers?
Oven reheating preserves texture best: cover with foil and bake at 350°F for 15-20 minutes. For quick fixes, microwave individual portions on 70% power in 30-second bursts, adding 1 tbsp milk to prevent dryness. Avoid reheating in the microwave for more than 2 minutes at a time.
Can I use a different type of potato?
Yukon Golds are ideal, but Russets or red potatoes work in a pinch. For extra creaminess, parboil them 5 minutes longer to soften. Avoid waxy potatoes like red skins—they won't hold their shape as well in the creamy sauce.
