Ingredients for betty crocker au gratin potatoes chicken
Sixteen essential ingredients crafting a restaurant-worthy Betty Crocker-inspired masterpiece with crispy celery crowns and velvety cheese layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Thinly sliced, peeled |
| Boneless, Skinless Chicken Thighs 🍗 | 1 ½ lb | Pounded to even thickness |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for richness |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | 1 cup | Shredded, adds nutty depth |
| Celery Stalks 🧅 | 1 bunch | Thinly sliced, fresh preferred |
| Panko Breadcrumbs 🍞 | 1 cup | For celery crown topping |
| Fresh Thyme Leaves 🌿 | ¼ cup | Chopped, aromatic freshness |
| Garlic Cloves 🧄 | 4 cloves | Minced, for depth of flavor |
| Chicken Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Unsalted Butter 🧈 | ½ cup | Melted, for sauce richness |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns preferred |
| All-Purpose Flour 🌾 | ½ cup | For breading chicken |
| Large Eggs 🥚 | 2 whole | Beaten, for chicken coating |
The Gruyère and sharp cheddar combination is non-negotiable for that signature Betty Crocker flavor profile—Whole Foods bulk bins or Gorton's cheese counters offer the best quality. Look for Gruyère with visible nutty flecks and cheddar with sharp tang rather than mild varieties. For the celery crown, fresh celery from the produce section (not pre-cut) yields the crispest texture. The Panko breadcrumbs should be light and airy—Japanese Panko from Trader Joe's delivers the perfect crunch. Fresh thyme and garlic elevate the dish, so organic herbs at Costco or local farmers' markets ensure maximum flavor.
No Gruyère? Swiss cheese works in a pinch, though the flavor will differ slightly. Pre-shredded cheese loses moisture—grate your own from a block for optimal melt. Substituting heavy cream with half-and-half lightens the texture but reduces richness. For the celery crown, water chestnuts can replace celery if you prefer a sweeter crunch. The chicken thighs should be pounded to even thickness (about ¼-inch) for consistent cooking. If using chicken breasts, brine them first to prevent dryness. Diamond Crystal kosher salt is preferred over table salt for its coarse texture and clean flavor—it dissolves better in the sauce.
Store prepped ingredients strategically: Shredded cheese in an airtight container with parchment paper between layers keeps for up to 3 days in the fridge. Celery crown topping can be prepped ahead and refrigerated for 24 hours before baking. The chicken should be marinated at least 1 hour (overnight for best results) and kept covered in the fridge. Assembled au gratin reheats beautifully—cover with foil and bake at 375°F for 20 minutes to restore crispiness. Leftovers keep for 4 days refrigerated or 3 months frozen, though the celery crown loses crispness when reheated—best served fresh.

Step-by-step instructions for celery crown crunch au gratin potatoes
A perfect blend of crispy chicken, creamy potatoes, and celery crown topping awaits.
🍳 Step 1: Prepare the Chicken and Celery Crown Topping
Begin by pounding the 1.5 lb boneless, skinless chicken thighs to an even ½-inch thickness between two sheets of plastic wrap using a meat mallet. This ensures even cooking. Season both sides generously with 1.5 tsp Diamond Crystal kosher salt and 1 tsp freshly ground black pepper. In a shallow bowl, whisk together the 2 whole large eggs and 0.5 cup all-purpose flour to create a breading station.
Dredge each chicken thigh in the flour mixture, pressing gently to adhere, then dip into the beaten eggs, letting excess drip off. Transfer to a plate and set aside. For the celery crown, thinly slice the 1 bunch celery stalks into ¼-inch rounds. In a small bowl, combine the sliced celery with 1 cup panko breadcrumbs, 0.25 cup chopped fresh thyme leaves, and 1 tsp freshly ground black pepper. Set aside until ready to use.
🥘 Step 2: Cook the Chicken and Layer the Potatoes
Heat 0.5 cup unsalted butter in a large oven-safe skillet over medium-high heat. Add the breaded chicken thighs and cook for 4-5 minutes per side until golden brown and cooked through to an internal temperature of 165°F. Remove the chicken and set aside on a plate. Reduce the heat to medium and add 4 minced garlic cloves, sautéing for 30 seconds until fragrant.
In the same skillet, pour in 1.5 cups chicken broth and scrape up any browned bits from the bottom. Bring to a gentle simmer, then stir in 1.5 cups heavy cream and 1.5 tsp Diamond Crystal kosher salt. Remove from heat and set aside. In a large bowl, toss the 3 lb thinly sliced russet potatoes with 1 cup shredded sharp cheddar cheese and 1 cup shredded Gruyère cheese. Arrange half the potatoes in the skillet in a single layer, slightly overlapping. 3
🔥 Step 3: Assemble and Bake to Golden Perfection
Top the potatoes with the cooked chicken thighs, then add the remaining potatoes, pressing down gently to create an even layer. Pour the cream mixture evenly over the top, ensuring every potato slice is coated. Sprinkle the celery crown mixture evenly over the entire surface, pressing down lightly to help it adhere. The celery crown should form a crispy, golden layer when baked.
Transfer the skillet to a preheated 375°F oven and bake for 45-50 minutes until the potatoes are tender and the celery crown is deep golden brown and crispy. If the top begins to brown too quickly, tent loosely with aluminum foil. The dish is done when a knife inserted into the potatoes slides in easily and the celery crown is crisp to the touch.
🔪 Step 4: Rest and Serve with ConfidenceRemove the skillet from the oven and let the au gratin rest for 10 minutes before serving. This resting period allows the layers to set and the flavors to meld, ensuring each bite delivers the perfect balance of creamy potatoes, crispy chicken, and crunchy celery crown. Serve immediately, garnished with additional chopped fresh thyme leaves if desired, and enjoy the harmonious blend of textures and flavors.
Pro Tips For Making Betty Crocker Au Gratin Potatoes Chicken
- PARBOIL POTATOES FIRST: Russet potatoes take forever to cook through in the oven, and you’ll end up with a dry, gummy mess if you skip this. Boil them whole for 8-10 minutes first—just until a knife slides in easily—then cool before slicing. (Yes, even if you’re impatient like me.)
- USE COLD CREAM: Heavy cream straight from the fridge whips into a richer sauce and doesn’t curdle under the chicken’s heat. Let it sit out for 10 minutes max—just enough to soften—but don’t let it warm up before mixing. (Your future self will notice the difference.)
- COOK CHICKEN UNTIL 165°F: Raw chicken in au gratin is a food safety nightmare, but overcooking it turns it rubbery. Pull it at 160°F, let it rest 5 minutes, then check again—it’ll hit 165°F. Slice it thin so it absorbs the creamy cheese sauce without turning to mush.
- GRATE CHEESE FRESH: Pre-shredded cheese has anti-caking agents that make the sauce grainy and watery. Grate your own sharp cheddar and Gruyère on a box grater—it melts smoother and browns better. (I know, it’s a pain, but trust me on this.)
Make-ahead tips for betty crocker au gratin potatoes chicken
Prep Ahead for Chicken
Marinate the chicken thighs overnight in a ziplock bag with 1 tbsp olive oil, 1 tsp kosher salt, ½ tsp black pepper, and 1 tsp chopped thyme. Store in the fridge for up to 24 hours—this keeps them juicy and flavorful.
I like to prep the marinade first thing in the morning so it’s ready when I’m ready to cook. 🍗
Layer Potatoes Early
Slice and toss the potatoes with cheese up to 24 hours ahead, storing them in an airtight container. Keep them refrigerated until ready to assemble—this prevents sogginess.
I often do this the night before so I can focus on cooking the chicken fresh. The potatoes stay firm and ready for baking.
Celery Crown Prep
Mix the celery crown topping ingredients in a bowl and refrigerate for up to 12 hours. This allows the flavors to meld slightly, ensuring a cohesive crunch when baked.
Store it in a sealed container to keep the celery crisp. I prep this right after slicing the celery to avoid wilting. 🧅
Assemble and Chill
Arrange the potatoes and chicken in the skillet up to 4 hours ahead, then refrigerate uncovered. This helps the layers set and prevents the potatoes from becoming waterlogged.
When ready to bake, simply add the cream mixture and celery crown, then bake as directed. This shortcut saves time and ensures even cooking.
Make-Ahead Baking
For a fully make-ahead option, assemble the entire dish (including cream sauce) and refrigerate for up to 12 hours. When ready to bake, cover tightly with foil and bake at 375°F for 50-60 minutes, adding 5-10 minutes uncovered to crisp the celery crown.
This method is perfect for holiday dinners—just pop it in the oven and let it shine. 💫
Nutrition facts
Frequently asked questions
Can I use chicken breasts instead of thighs?
Yes, but with precautions! Chicken breasts cook faster and can dry out. Pound them to ½-inch thickness and brine for 30 minutes in ¼ cup salt + 4 cups water to keep them juicy. Bake at 350°F instead of 375°F to prevent overcooking.
How do I make this dish vegetarian?
Replace chicken with 1.5 lb sliced portobello mushrooms or 1 lb extra-firm tofu (pressed and pan-fried). For protein, add 1 cup cooked lentils or 1 lb chickpeas to the potato layers. Use vegetable broth instead of chicken broth for the sauce.
Why is my celery crown not crispy?
Over-baking or moisture are the usual culprits. Bake uncovered for the last 5-10 minutes to crisp the top, and ensure your celery is thinly sliced (¼-inch) with minimal water content. Press the celery crown firmly when adding it to the dish—this helps it adhere and crisp better.
Can I make this in a regular baking dish instead of a skillet?
Use a 9x13-inch baking dish and reduce the oven temperature to 350°F to prevent uneven cooking. Bake for 50-55 minutes, covering with foil for the first 30 minutes to avoid over-browning. The texture will be similar, just slightly less crispy on the edges.
What’s the best way to reheat leftovers?
Cover with foil and reheat at 350°F for 20-25 minutes to restore creaminess. For extra crispiness, broil for 2-3 minutes at the end. Avoid microwaving—it makes the celery crown soggy. Store leftovers in an airtight container for up to 4 days.
