Step-by-Step Instructions
Prepare the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a large 9 × 13-inch baking dish with olive oil or butter.
Prepare the Chicken
Pat the chicken breasts dry with paper towels.
If the chicken breasts are very thick, gently pound them with a meat mallet until they have a relatively even thickness.
Season both sides with salt, black pepper, and half of the Italian seasoning.
Prepare the Potatoes
Wash the potatoes thoroughly.
Peel them if desired, although leaving the skins on gives the dish a more rustic appearance.
Slice the potatoes into approximately ½-inch rounds.
Place them in a bowl and toss with a little salt, black pepper, and the remaining Italian seasoning.
Arrange the Casserole
Place the seasoned chicken breasts in the center of the prepared baking dish.
Arrange the potato slices around the chicken in an overlapping pattern.
Try to keep the potatoes relatively evenly distributed so they cook consistently.
Make the Garlic Butter Sauce
In a medium bowl, whisk together the heavy cream, chicken broth, melted butter, minced garlic, and remaining Italian seasoning.
If using Parmesan cheese in the sauce, whisk it in at this stage.
Mix until everything is evenly combined.
Add the Sauce
Slowly pour the creamy garlic butter mixture over the chicken and potatoes.
Use a spoon or spatula to distribute the garlic and seasonings evenly.
Bake
Cover the baking dish loosely with aluminum foil.
Bake at 400°F (200°C) for approximately 25 minutes.
Remove the foil and continue baking for another 15–20 minutes.
The chicken should reach an internal temperature of 165°F (74°C), while the potatoes should be tender when pierced with a fork.
Create a Golden Finish
For an attractive golden-brown top, switch the oven to broil on high.
Broil for approximately 2–3 minutes.
Watch the dish carefully because the cream, butter, and cheese can brown quickly.
Rest and Garnish
Remove the casserole from the oven.
Allow it to rest for 5–10 minutes.
The sauce will thicken slightly as it cools.
Sprinkle generously with freshly chopped parsley and additional Parmesan if desired.
Serve warm.
Best Tips
Slice the potatoes evenly: Approximately ½-inch slices allow the potatoes to cook at a similar rate.
Pound thick chicken breasts: Even thickness helps prevent some portions from becoming dry while thicker areas remain undercooked.
Use full-fat cream: It creates a richer and more stable sauce.
Do not skip the resting period: The sauce thickens naturally after the casserole comes out of the oven.
Check the chicken temperature: Use an instant-read thermometer and make sure the thickest part reaches 165°F (74°C).
Avoid excessive broiling: A couple of minutes is enough to create a golden finish.
Best Ingredient Options
Yukon Gold or yellow potatoes work particularly well because they have a naturally buttery texture and hold their shape while becoming tender.
Air-chilled chicken breasts can be a good choice because they tend to release less excess liquid during cooking.
Fresh garlic provides a stronger flavor than jarred minced garlic.
For an even richer sauce, freshly grated Parmesan can be added before baking.
Recipe Variations
🧀 Parmesan Garlic Chicken
Add ½ cup freshly grated Parmesan over the casserole during the final 10 minutes of baking.
🌿 Herb Chicken and Potatoes
Add fresh rosemary, thyme, parsley, or basil to the cream sauce.
🥦 Chicken, Potato and Broccoli
Add broccoli florets during the final 15 minutes of baking so they remain tender without becoming overly soft.
🥬 Spinach Garlic Chicken
Add several handfuls of fresh spinach during the final 10 minutes of cooking.
🍄 Creamy Mushroom Chicken
Sauté sliced mushrooms until lightly browned and add them to the casserole before baking.
What to Serve With
Because this casserole is rich and creamy, a crisp green salad with lemon vinaigrette makes an excellent side.
Steamed broccoli, green beans, asparagus, or roasted Brussels sprouts also pair beautifully with the garlic butter sauce.
For a more indulgent meal, serve it with warm crusty bread to soak up the creamy sauce.
Make-Ahead Instructions
You can season the chicken and slice the potatoes up to 24 hours ahead.
Store the chicken covered in the refrigerator.
If preparing the potatoes ahead, place the slices in cold water in the refrigerator to prevent browning.
Drain and thoroughly pat them dry before assembling the casserole.
For the best results, prepare the cream sauce immediately before baking.
Storage
Allow leftovers to cool before transferring them to airtight containers.
Refrigerate for up to 4 days.
Store the chicken, potatoes, and sauce together so the potatoes can absorb the flavorful sauce as they sit.
Reheating
For individual portions, place the food in a microwave-safe dish.
Cover loosely and heat at medium power in 30–60 second intervals until completely heated.
For better texture, reheat in a covered oven-safe dish at 350°F (175°C) for 15–20 minutes.
If the sauce has thickened considerably, add a small splash of chicken broth or milk before reheating.
Freezing
This casserole can technically be frozen, although creamy sauces may change texture slightly after thawing.
Allow the casserole to cool completely before transferring individual portions to freezer-safe containers.
Freeze for up to 2 months.
Thaw overnight in the refrigerator.
Reheat gently in the oven at 325–350°F (165–175°C) until heated through.
Common Mistakes to Avoid
Slicing potatoes too thick: Thick potatoes may remain firm while the chicken becomes overcooked.
Using uneven chicken breasts: Different thicknesses can lead to inconsistent cooking.
Using low-fat milk instead of cream: The sauce may be less rich and can be more prone to separating.
Overcrowding the potatoes: Arrange them so the hot sauce and oven heat can circulate around them.
Skipping the temperature check: Always verify that the thickest part of the chicken reaches 165°F (74°C).
Broiling too long: Keep a close eye on the casserole during the final few minutes.
