Ingredients for betty crocker au gratin potatoes chicken

Simple ingredients that transform into a showstopping one-pan dinner everyone will love.

The potatoes are the star here, so pick Russets—they're the starchy, fluffy kind that holds up perfectly. Costco or Trader Joe's usually have them pre-bagged for easy slicing. I always peel mine for a cleaner look, but the skin adds texture if you leave it on. The chicken? Boneless, skinless breasts are easiest, but thighs stay juicier. Pound them thin so they cook through while the potatoes bake. Don't skip the pounding—thick pieces turn rubbery. For the cheese, sharp cheddar and Gruyère give that classic au gratin flavor, but Parmesan works too if you're in a pinch.

No Gruyère? Substitute extra cheddar or Swiss—it'll still taste amazing. Fresh thyme is ideal, but dried works at one-third the amount. The chicken broth can be bouillon cubes in a pinch, but low-sodium is key so you control the saltiness. For the breadcrumbs, panko gives extra crunch, but regular breadcrumbs work fine. The butter topping is non-negotiable—it creates that golden, crispy crust. If you're out, melted margarine works in a bind, but butter is worth the splurge here. And yes, you can make this ahead—just add the cheese right before baking.

This dish reheats beautifully—honestly tastes better the next day once everything melds together. Store leftovers covered in the fridge for up to 4 days, or freeze for 3 months. I always make a double batch because it disappears fast. The crispy topping gets soggy if you freeze it, so add that fresh when reheating. For serving, a simple green salad with lemon vinaigrette cuts through the richness. Leftovers? Microwave with a splash of milk to revive the crispy top.

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

Here's how to create a showstopping one-pan dinner that combines crispy chicken with creamy, cheesy potatoes.

Preheat your oven to 375°F. Peel and thinly slice the 3 lb russet potatoes into ¼-inch thick rounds. I like to use a mandoline for even slices, but a sharp knife works too. Toss the potato slices with 1 tbsp olive oil, ½ tsp salt, and ½ tsp black pepper until evenly coated.

In a large oven-safe skillet (I use a 12-inch cast iron for even browning), arrange half the potato slices in a single layer, slightly overlapping. You want them to fit snugly but not too tightly—this ensures they cook evenly. Sprinkle with ½ cup sharp cheddar cheese and ¼ cup gruyère cheese, pressing gently so they adhere. Repeat with the remaining potato slices and cheeses.

While the potatoes cook, pound the 2 lb boneless chicken breasts to ½-inch thickness between two sheets of plastic wrap. Season both sides generously with 1 tsp salt, ½ tsp black pepper, and ½ tbsp chopped fresh thyme leaves. Heat 1 tbsp olive oil in a separate skillet over medium-high heat until shimmering.

Cook the chicken for 4-5 minutes per side until golden brown and the internal temperature reaches 160°F. The chicken should release easily from the pan—if it sticks, let it cook a bit longer. Transfer the chicken to a plate and tent loosely with foil to keep warm. This step ensures juicy chicken that won't dry out during the final bake.

In a medium bowl, whisk together the 1.5 cups heavy cream, 1.5 cups chicken broth, 0.25 cup all-purpose flour, 1 tbsp chopped fresh thyme leaves, 1 tsp salt, ½ tsp black pepper, and 4 minced garlic cloves. The mixture should be smooth—if it's too thick, whisk in 1-2 tablespoons of water until it reaches a pourable consistency.

Carefully pour the sauce mixture over the layered potatoes in the skillet. The sauce should seep down between the layers, creating a rich, creamy base. If any potatoes are peeking out, gently press them down with a spatula to ensure even coverage. This step is where all the magic happens—don't skip it!

Transfer the skillet to the preheated oven and bake for 45-50 minutes until the potatoes are tender when pierced with a fork and the top is golden brown. About halfway through baking, sprinkle the remaining 1 cup sharp cheddar cheese and ½ cup gruyère cheese over the top. This creates a delicious, bubbly cheese crust.

For extra crispiness, remove the skillet from the oven and stir the melted 0.5 cup unsalted butter into the sauce until fully incorporated. Return to the oven for an additional 5-7 minutes to let the butter melt and create a luscious, golden finish. The edges should be crispy, and the cheese should be bubbly and slightly browned.

Slice the cooked chicken into ½-inch thick strips and arrange them on top of the potatoes. Return the skillet to the oven for 5-7 minutes to heat the chicken through and let the flavors meld together. The chicken should reach an internal temperature of 165°F, ensuring it's fully cooked and safe to eat.

Remove from the oven and let it rest for 5 minutes before serving. This resting time allows the juices to redistribute, ensuring every bite is moist and flavorful. Garnish with extra black pepper and chopped fresh thyme leaves for a pop of color and freshness. Serve immediately with a side of steamed green beans or a simple salad for a complete meal!

Essential equipment for this recipe

Oven-Safe Skillet

This recipe demands a large, oven-safe skillet—I swear by a 12-inch cast iron skillet from Lodge because it distributes heat evenly and creates that signature crispy bottom. If you don’t have cast iron, a stainless steel skillet or enamel Dutch oven works too.

Just avoid nonstick—it can’t handle the high heat needed for that golden crust. 🔥

Mandoline Slicer

For even, thin potato slices, a mandoline slicer is a game-changer. The OXO Good Grips model is my go-to because it’s safe and adjustable. If you don’t own one, a sharp chef’s knife and steady hand will work, but be extra careful—thick slices won’t cook through evenly.

Aim for ¼-inch slices for perfect texture.

Measuring Tools

Precision matters here, especially with the cheese-to-sauce ratio. Invest in a digital kitchen scale for accurate cheese measurements—I use the OXO Good Grips scale for its readability. For liquids, a liquid measuring cup ensures you hit the 1.5 cups heavy cream mark without spills.

A fine-mesh strainer also helps when mincing garlic for a smoother sauce.

Cheese Grater

Pre-shredded cheese is a no-go—it’s packed with anti-caking agents that make the sauce grainy. A hand crank grater like the Microplane gives you fresh, fine shreds of cheddar and Gruyère.

For extra efficiency, I grate cheese directly over the skillet to avoid mess. Pro tip: Chill the cheese before grating for easier handling and cleaner slices.

Instant-Read Thermometer

Two temperatures are critical: 160°F for chicken and 210°F for potatoes (when fork-tender). A ThermoWorks Thermapen is my favorite because it’s fast and accurate. For the chicken, check the thickest part—it should reach 165°F after the final bake. This ensures juicy, safe-to-eat protein every time. 🌡️

Mixing Bowls & Whisk

The sauce must be smooth and lump-free, so a medium mixing bowl and a balloon whisk are essential. I use pyrex glass bowls because they’re heat-resistant and easy to clean. For whisking, a siliconized whisk prevents sauce from sticking to the wires.

If your sauce thickens unexpectedly, add 1 tbsp water at a time until it’s pourable but still coats the back of a spoon.
