Ingredients for betty crocker au gratin potatoes chicken
Six ingredients make this creamy, crispy chicken and au gratin masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Thighs 🍗 | 2 lb | Cut into even strips for even cooking |
| Russet Potatoes 🥔 | 3 lb | Thinly sliced, peeled (optional) |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for best creaminess |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, sharp flavor preferred |
| Celery Stalks 🧅 | 3 whole | Thinly sliced for crispy crust |
| All-Purpose Flour 🌾 | ½ cup | For celery crust binding |
| Butter 🧈 | ½ cup | Unsalted, melted for sauce |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Garlic Cloves 🧄 | 4 cloves | Minced for flavor depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Gruyère Cheese 🧀 | ½ cup | Shredded, for extra richness |
The chicken thighs are your secret weapon here—Costco or butcher sections have the best cuts, but any store's pre-cut thighs work. Look for even-sized pieces so they cook at the same rate. If you're using breasts, pound them to even thickness so they don't dry out. The potatoes should be firm and starchy—Russets are ideal, but Yukon Golds add a touch of sweetness. Walmart or Trader Joe's usually have pre-sliced potatoes if you're short on time, but slicing them yourself gives you control over thickness. Thin slices mean more crispy edges!
No sharp cheddar? Pepper Jack adds heat, or Gruyère for nutty depth. The celery crust is non-negotiable—it's what gives this dish that restaurant-worthy crunch. Swap the flour for crushed crackers if you're out, but trust me, the flour keeps it light. Heavy cream can be substituted with half-and-half (though it won't be as rich), and low-fat milk will make the sauce separate. For the celery, don't skip the thin slicing—use a mandoline if you've got one, or ask your butcher to slice it. Fresh parsley is optional but adds that bright pop of color that makes the dish look fancy.
This dish reheats like a dream—just cover with foil and warm at 350°F for 15-20 minutes. Keeps for 4 days in the fridge or 3 months frozen. Double the recipe and freeze half for lazy weeknights. The celery crust gets soggy if reheated uncovered, so cover it tightly with foil. For meal prep, assemble the dish ahead but bake it fresh—the crust won't crisp up properly if baked from frozen. Garnish with extra parsley right before serving to keep it looking fresh!

- One-Pan Magic: I swear by this recipe because it’s literally one pan—no fussing with multiple dishes. Slice the potatoes, sear the chicken, dump in the celery and cream, then bake. That’s it. (Yes, even on a Tuesday night when I’d rather be scrolling TikTok.)

- Budget Dinner Hero: Russet potatoes and chicken thighs stretch this recipe for a crowd without breaking the bank. Heavy cream feels fancy, but it’s a small splurge that makes everything taste like you actually tried. Plus, celery adds crunch for pennies—win, win.
Step-by-step instructions for chicken and au gratin potatoes
This method delivers the perfect balance of crispy celery crust and creamy cheesy layers every time.
Prepare the Chicken and Celery Crust
Cut the 2 lb boneless, skinless chicken thighs into even 1-inch strips. Season immediately with ½ tsp of the 1.5 tsp salt and ¼ tsp of the 0.5 tsp black pepper. Set aside while you prepare the celery crust.
Thinly slice the 3 whole celery stalks and place them in a food processor. Add the 0.5 cup all-purpose flour and pulse until finely chopped. Transfer to a bowl and stir in ½ cup of the 2 cups sharp cheddar cheese and the 0.5 cup gruyère cheese. This crispy topping is what makes this dish truly special.
Layer the Potatoes and Create Creamy Base
Preheat your oven to 375°F. Thinly slice the 3 lb russet potatoes and arrange them in a single layer in a 9x13-inch baking dish, slightly overlapping. Sprinkle with the remaining 1 tsp salt and ¼ tsp black pepper.
In a saucepan, melt the 0.5 cup butter over medium heat. Add the 4 minced garlic cloves and sauté for 30 seconds until fragrant. Pour in the 1.5 cups heavy cream and 1 cup chicken broth, stirring constantly until smooth. Remove from heat and stir in the remaining 1½ cups sharp cheddar cheese until fully melted and creamy.
Assemble and Bake to Golden Perfection
Pour the creamy cheese mixture evenly over the potato layers, pressing down gently to help it settle. Sprinkle the celery cheese mixture evenly over the top, pressing down lightly to create that signature crispy crust.
Bake uncovered for 45 minutes. Then, increase the oven temperature to 400°F and bake for another 20-25 minutes until the top is golden brown and the potatoes are tender when tested with a fork. The edges should be bubbling and the crust should be crispy to the touch.
Cook the Chicken and Combine
While the potatoes bake, heat 1 tablespoon olive oil in a skillet over medium-high heat. Add the seasoned chicken strips and cook for 5-6 minutes, stirring occasionally, until golden brown and cooked through. Transfer to a plate and tent with foil to keep warm.
Once the potatoes are fully baked, remove from the oven and let sit for 5 minutes. Spoon the chicken strips and any accumulated juices over the top of the potatoes. Garnish with the 0.25 cup chopped fresh parsley and serve immediately while the crust is still crispy and the cheese is bubbly.
Pro Tips For Making Betty Crocker Au Gratin Potatoes Chicken
- BRINE THE CHICKEN: Toss those chicken thighs in saltwater for 15-20 minutes before cooking—yes, even boneless ones. I used to skip this, and the meat always ended up dry and stringy. The salt keeps them juicy through the long bake, and the flavor? Way more balanced than plain seasoning.
- SLICE POTATOES THIN: Cut the russets ⅛-inch thick, no thicker. Thicker slices mean uneven cooking—some mushy, some raw—and that’s a disaster in au gratin. A mandoline makes this faster, but if you’re doing it by hand, take your time. The even layers are what make this dish work.
- SAUCE FIRST, LAYERS SECOND: Mix the heavy cream, cheese, and celery before assembling the dish. I learned this after one soggy, uneven batch where the sauce pooled at the bottom. Spread a thin layer of sauce on the bottom of the dish first, then alternate layers with sauce in between. Every. Single. Layer.
- COVER IT HALFWAY: Bake uncovered for the first 20 minutes at 375°F—this gets the top golden and crispy. Then, tent loosely with foil for the last 20-25 minutes. Skipping this step means a sad, watery top, and nobody wants that. The cheese should melt into a glossy blanket, not a greasy mess.
Storing and reheating your betty crocker au gratin potatoes chicken
Refrigerator Storage
Store your leftovers in an airtight container with a tight-fitting lid to maintain that crispy celery crust. I recommend glass Pyrex containers—they distribute heat evenly and prevent freezer burn.
Keep the dish refrigerated for up to 4 days, but I find the texture and flavor stay best within 2-3 days. The celery crust may soften slightly, so plan to re-crisp it when reheating. 🥔
Freezer-Friendly Tips
This dish freezes beautifully for up to 3 months—just assemble it completely (including the celery crust) and cover tightly with plastic wrap followed by aluminum foil. When ready to eat, thaw overnight in the fridge, then reheat covered at 350°F for 30-40 minutes.
The celery crust won’t be as crispy as fresh, but it’ll still taste amazing. 🧊
Reheating for Crispy Perfection
For the best results, reheat covered with foil at 350°F for 15-20 minutes—this keeps the potatoes creamy while the celery crust re-crispifies. If you’re short on time, use the microwave: Cover with a damp paper towel and heat on high for 3-4 minutes, stirring halfway.
Finish under a broiler for 1-2 minutes to restore that golden crust. 🔥
Make-Ahead Assembly
Save time by assembling the dish ahead—layer the potatoes, cheese sauce, and celery crust in your baking dish, but skip the chicken. Cover and refrigerate for up to 24 hours before baking.
When ready, add the chicken and bake as directed. This is a game-changer for busy weeknights! The flavors meld beautifully overnight. ⏰
Garnish Before Serving
Fresh parsley or green onions add a bright pop of color and freshness. Sprinkle them on top right before serving—they’ll wilt if added too early. For extra flair, toast breadcrumbs with a pinch of garlic powder and sprinkle over the hot dish.
This adds a crunchy contrast to the creamy potatoes. 🌿
Portion Control
This dish serves 6 hungry people, but leftovers are inevitable. Divide into individual portions before storing to make reheating easier. I like using small glass containers—they’re microwave-safe and make it simple to grab a single serving. Label with the date to track freshness. 📅

Frequently asked questions
Can I use chicken breasts instead of thighs?
Yes, but pound them to ¼-inch thickness to prevent drying. Chicken breasts cook faster than thighs, so they'll need only 4-5 minutes in the skillet. For extra moisture, marinate them in 1 tablespoon lemon juice and 1 teaspoon olive oil for 20 minutes before cooking.
Why is my celery crust soggy?
Soggy crusts happen when the cheese sauce steams too much. Press the celery mixture down firmly before baking, and bake at 400°F for the final 20-25 minutes to crisp it. For extra insurance, sprinkle ¼ cup breadcrumbs over the celery topping before baking.
How do I make this dish dairy-free?
Replace the heavy cream with 1.5 cups full-fat coconut milk and the cheddar with 2 cups dairy-free shreds (like Violife or Daiya). Use ½ cup nutritional yeast for a cheesy flavor. The celery crust will still work with ½ cup flour + ½ cup almond flour.
Can I prepare this dish ahead of time?
Assemble everything (except the chicken) in the baking dish up to 24 hours ahead and refrigerate. When ready to bake, add the chicken and cook as directed. For a freezer-friendly version, assemble completely, cover tightly, and freeze for up to 3 months. Thaw overnight before baking.
What's the best way to serve this with sides?
Pair with a crisp green salad (arugula + lemon vinaigrette) or steamed asparagus with garlic butter. For a heartier meal, add crusty French bread or dinner rolls to soak up the creamy sauce. A glass of Chardonnay or Sauvignon Blanc complements the dish beautifully.
