Ingredients for copycat costco chicken bake
Six ingredients make this crispy chicken bake taste just like Costco's iconic dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Thighs 🍗 | 2 lb | Cut into 1-inch pieces |
| Baby Potatoes 🥔 | 2 lb | Halved, not peeled |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, mild or sharp |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated from block |
| Panko Breadcrumbs 🍞 | 1 cup | For crispy topping |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Garlic Cloves 🧄 | 4 cloves | Minced for flavor |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening sauce |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Dried Thyme 🍃 | 1 tsp | Or 1 tbsp fresh |
| Olive Oil 🫒 | 2 tbsp | For browning chicken |
The chicken thighs are key—bone-in, skin-on gives the best flavor, but boneless works too. Costco or Trader Joe's sell them pre-cut, saving you time. Look for thighs with good marbling (that white fat) for juiciness. Baby potatoes add heartiness, and Yukon Golds work best for their creamy texture. The cheddar should be the sharp variety—it melts better and adds more depth. For the breadcrumbs, Panko is non-negotiable—it stays crispy while regular breadcrumbs turn soggy.
No panko? Crushed cornflakes or Ritz crackers work in a pinch, but texture won't be the same. Short on heavy cream? Half-and-half plus a splash of milk gets you close. The cheese can be swapped for Monterey Jack or Gouda if you're out of cheddar. For extra richness, add 1/4 cup sour cream to the sauce. The garlic and onion are flavor anchors—don't skip them. If you're prepping ahead, cook the chicken and potatoes first, then assemble before baking for that restaurant-quality finish.
This dish reheats beautifully—just add a splash of milk or broth to revive the crispy top. Keeps in the fridge for 4 days or freezes for 3 months. For make-ahead meals, bake it ahead, cool completely, then refrigerate. The flavors actually improve overnight as everything melds. Portion into containers for easy lunches—just microwave with a damp paper towel on top to keep the breadcrumbs crispy.

Step-by-step instructions for copycat Costco chicken bake
Here's how to recreate that iconic crispy-topped, cheesy comfort dish in your own kitchen.
Prep the Chicken and Potatoes
Cut the 2 lb boneless, skinless chicken thighs into 1-inch pieces and pat them dry with paper towels. This helps the breading stick better. In a large bowl, toss the chicken with 1.5 tsp salt, 0.5 tsp black pepper, and 1 tsp dried thyme. Set aside while you prepare the potatoes.
Halve the 2 lb baby potatoes (no need to peel them) and place them in a separate bowl. Drizzle with 2 tbsp olive oil, then toss until each half is evenly coated. Spread the potatoes on a baking sheet and roast at 425°F for 20 minutes until they begin to soften slightly. This jump-start ensures they cook through without becoming mushy later.
Build the Crispy Breaded Chicken
In a shallow dish, combine the 1 cup panko breadcrumbs, 0.5 cup parmesan cheese, and 1 tbsp all-purpose flour. This mix creates the signature crispy crust. Dip each piece of seasoned chicken into the 1 cup heavy cream (just enough to lightly coat), then press firmly into the breadcrumb mixture, ensuring full coverage. Place the breaded chicken on a wire rack set over a baking sheet to drain any excess cream.
Here's the thing—don't skip the draining step. If the breading gets soggy, you won't get that perfect crunch. Let the chicken rest on the rack for 5 minutes while you prep the rest of the components.
Sauté the Aromatics for Flavor Base
Heat 0.5 cup butter in a large oven-safe skillet over medium heat. Add the 1 whole yellow onion, diced, and cook for 5 minutes until softened. Stir in the 4 cloves garlic, minced, and cook for another 30 seconds until fragrant. This aromatic base forms the flavor foundation for the entire dish.
Pour in the 1 cup chicken broth and bring to a gentle simmer. Sprinkle the 2 cups sharp cheddar cheese over the top and stir until it melts completely, creating a smooth, creamy sauce. This step is where the magic happens—don't rush it. The cheese should fully incorporate before moving forward.
Assemble and Bake to Golden Perfection
Arrange the breaded chicken pieces evenly over the cheese sauce in the skillet. Top with the pre-roasted baby potatoes, nestling them gently among the chicken. The potatoes should be partially submerged in the sauce, ensuring they absorb flavor while staying tender.
Transfer the skillet to a 425°F preheated oven and bake for 25-30 minutes until the chicken is cooked through (internal temperature reaches 165°F) and the top is deep golden brown with crispy edges. The cheese should be bubbly and slightly browned—this is your visual cue that it's ready.
Rest and Serve with Crispy Top
Remove the skillet from the oven and let the dish rest for 5 minutes before serving. This resting period allows the juices to redistribute, ensuring each bite is moist and flavorful. The top should remain crispy—if it softens too much, broil for 1-2 minutes at the end to restore the crunch.
Serve immediately with a side of crusty bread to soak up the creamy sauce. The combination of tender chicken, crispy potatoes, and that perfect cheesy crust makes this dish irresistibly comforting. Leftovers? They reheat beautifully in the oven at 350°F for 10-15 minutes until warmed through.
Pro Tips For Making Copycat Costco Chicken Bake
- Pre-Roast Potatoes Properly: That 20-minute head start at 425°F isn’t just about speed—it’s about texture. Skipping it means mushy potatoes later, and no one wants that. Spread them in a single layer so they crisp slightly on the edges before going into the skillet.
- Grate Parmesan Fresh: Pre-shredded parmesan turns to powder when baked. Grab a block and use a box grater—it’s worth the extra 30 seconds for that nutty, crispy bite in the breading. Trust me, the difference is noticeable.
- Don’t Crowd the Chicken: Overlapping breaded chicken steams instead of crisps. Give each piece space on the wire rack, even if it means two batches. The airflow is non-negotiable for that golden crust—no one wants soggy breading.
- Broil for Crispiness: If the top loses its crunch after resting, hit it with 1-2 minutes under the broiler. Watch like a hawk—cheese burns faster than you think. A few minutes of attention at the end makes all the difference.
Perfect pairings for copycat costco chicken bake
Classic Side Pairings
A warm, crusty baguette is my go-to side for this dish—its texture soaks up the creamy cheese sauce beautifully. I like to slice it into ½-inch thick pieces and toast them in the oven at 375°F for 5 minutes until golden.
For a lighter option, serve with a simple mixed greens salad tossed with 1 tbsp olive oil, 1 tbsp red wine vinegar, and a pinch of salt. The acidity cuts through the richness of the chicken bake perfectly. 🥖
Creamy Sauce Upgrades
For an extra indulgent touch, drizzle the finished dish with sour cream or crème fraîche—just 2 tbsp adds a tangy contrast that elevates every bite. I also love sprinkling fresh parsley or chives over the top for a pop of color and freshness.
If you're feeling adventurous, swap ½ cup of the sharp cheddar for Monterey Jack in the sauce for a milder, creamier finish. 🌿
Beverage Pairings
A crisp Sauvignon Blanc from New Zealand is my top wine pairing—its citrus notes complement the creamy sauce without overpowering the dish. For beer lovers, a Belgian witbier like Hoegaarden adds a refreshing, slightly spicy contrast.
If you prefer non-alcoholic options, sparkling apple cider or iced hibiscus tea both work wonderfully to cleanse the palate. 🍷
Make-Ahead Serving Tips
If you're prepping ahead, assemble the dish but skip the final baking step. Cover and refrigerate for up to 24 hours, then bake as directed.
For serving, transfer the baked dish to a warm platter and garnish with extra Parmesan cheese or a sprinkle of crushed red pepper flakes for a restaurant-worthy finish. The crispy breadcrumb topping stays intact if you reheat leftovers in a 350°F oven for 10 minutes. 💡
Kid-Friendly Adaptations
For picky eaters, serve the chicken and potatoes separately from the sauce. Kids can build their own mini-bakes with just the components they like. You can also swap the Panko breadcrumbs for crushed cornflakes to make the topping sweeter and more appealing.
A side of apple slices or carrot sticks balances the meal nicely. 🍎
Garnish Like a Pro
Elevate your dish with a few simple garnishes: a drizzle of truffle oil adds luxury, while toasted breadcrumbs (toasted in 1 tbsp butter for 2 minutes) give extra crunch.
For a pop of color, scatter microgreens or edible flowers on top. I always finish with a pinch of smoked paprika to add depth without overpowering the flavors. ✨

Frequently asked questions
Can I use chicken breasts instead of thighs for this recipe?
Chicken thighs work best because they stay juicy and tender during baking. Chicken breasts will dry out more easily and won't have the same rich flavor. If you must use breasts, marinate them in 1 tbsp olive oil and 1 tsp thyme for at least 30 minutes before breading to help retain moisture.
Why did my breadcrumb topping get soggy?
Soggy breadcrumbs usually mean the chicken wasn't drained properly after breading. Always place breaded chicken on a wire rack for 5 minutes before baking to let excess moisture evaporate. Another trick: spread the breaded chicken on a baking sheet and refrigerate for 15 minutes before assembling the dish.
How do I make this dish ahead of time?
Assemble everything except the final baking step, then refrigerate for up to 24 hours. When ready to bake, transfer to a 425°F oven and bake for 30-35 minutes (5-10 minutes longer than fresh). For best results, cover tightly with foil before refrigerating to prevent drying. The flavors actually improve overnight!
Can I make this in a slow cooker?
This dish isn't ideal for a slow cooker because it relies on browning and crispy breadcrumbs. However, you can try this workaround: Brown the chicken and potatoes separately, then combine with the sauce in the slow cooker on Low for 2-3 hours. Top with extra breadcrumbs and broil for 2-3 minutes at the end to restore crispiness. The texture won't be identical, but it's a good backup option.
What's the secret to extra crispy breadcrumbs?
Use Panko breadcrumbs (never regular breadcrumbs) and toast them in a dry skillet for 2-3 minutes before mixing with Parmesan. For the final topping, sprinkle an extra 2 tbsp Panko on top right before baking. Also, broil for 1-2 minutes at the very end if the top loses crispiness during baking.
