Skinny Baked Chicken Potato Casserole Recipe
A skinny version of the classic baked chicken potato casserole. Made with lean chicken breast and flavored with onions, garlic, and fresh herbs. We use half the quantity of cheese and substitute some milk for cream. So it’s still rich, creamy, and absolutely delicious.

Picture succulent chicken bathed in a creamy sauce, accompanied by tender carrots, hearty potatoes, and a sprinkling of gooey cheese that will leave you craving for more.
Why is this the best recipe?
- The success of this recipe lies in the careful selection and combination of high-quality ingredients. Starting with tender chicken breast, the star protein of the dish, it provides a lean and healthy foundation. Then come the potatoes and carrots, adding substance and a delightful contrast of textures.
- But what truly elevates this recipe is the creamy sauce infused with cheese. Rich, velvety, and utterly indulgent, the sauce adds a luxurious touch to the otherwise wholesome ingredients.
- The cooking technique employed here is another reason for this recipe’s superiority. Baking the chicken instead of frying it reduces the amount of added fat, making it a healthier option without sacrificing taste. The slow and gentle cooking process ensures that the chicken is tender and juicy while the sauce and veggies perfectly meld together, creating a delectable symphony of flavors.

Ingredients and substitutes
- This dish’s heart is tender chicken breast, which provides a lean and protein-packed base. However, suppose you prefer a different protein source or want to switch things up. For a vegetarian twist, you can easily substitute chicken breast with boneless skinless chicken thighs or even tofu.
- Next up, we have the comforting addition of potatoes. Whether you prefer traditional russet potatoes or the creamy texture of Yukon golds, these starchy gems offer a satisfying and filling element to the dish. For those looking to reduce carbohydrates, you can substitute potatoes with cauliflower florets or even turnips for a flavorful alternative.
- Adding a pop of vibrant color and natural sweetness, carrots make a delightful addition to this baked chicken dish. However, if carrots aren’t to your liking, you can experiment with other root vegetables like parsnips or sweet potatoes for a slightly different flavor profile.
- To enhance the overall taste and aroma of the dish, we rely on the classic combination of garlic and onion powder. These pantry staples infuse the chicken and vegetables with a savory kick. If you don’t have these seasonings, you can substitute them with fresh minced garlic and finely chopped onions for a more robust flavor.
- A rich and velvety sauce ties everything together, and that’s where the combination of broth, flour, milk, and cream comes into play. While this recipe calls for chicken broth, you can easily swap it out with vegetable broth for a vegetarian-friendly version. Similarly, if you prefer a gluten-free option, you can substitute all-purpose flour with a gluten-free alternative like rice flour or almond flour.
- Last but not least, the melty goodness of the cheeses adds a final touch of indulgence to this delightful dish. The recipe calls for a blend of shredded mozzarella and Parmesan cheese. Still, you can experiment with cheeses such as cheddar, Gruyère, or even creamy goat cheese for a unique twist.

Step-by-step: Chicken potato casserole
- Preheat Oven: Preheat your oven to 325°F / 165°C / Gas mark 3. Grease a 9×13-inch baking dish and set it aside.
- Partially cook potatoes: boil the potatoes in salted water until they are tender but not soft. They will continue to cook while baking.
- Layer Casserole: In the prepared baking dish, layer the chopped chicken, diced partially cooked potatoes, and sliced carrots. Sprinkle garlic powder, onion powder, salt, and pepper evenly over the layers.
- Make the Sauce: In a bowl, whisk together the chicken broth and flour until there are no lumps. Add the milk and half and half. Season with salt and pepper.
- Assemble: Pour the creamy sauce evenly over the chicken and vegetable layers in the baking dish. Sprinkle the grated Parmesan, Gruyere, and mozzarella cheese over the top of the casserole.
- Bake: Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30-35 minutes, then remove the foil and bake for another 20 to 25 minutes or until the potatoes and carrots are tender when pierced with a fork.
- Serve: Remove the casserole from the oven, let it cool for a few minutes, and then serve hot.

Notes
- First and foremost, it’s essential to season your chicken properly before baking. Make sure to generously sprinkle salt, pepper, and other herbs or spices that suit your taste. This step not only enhances the flavor of the chicken but also adds complexity to the cream sauce.
- Next, when preparing the cream sauce, use low-fat ingredients if you aim for a skinny version of this dish. Opt for reduced-fat milk or half-and-half instead of heavy cream, and choose a light cream cheese option. These substitutions will help you keep the calorie count in check without compromising on taste.
- When it comes to baking the chicken, it’s important to monitor the cooking time to avoid drying out the meat. The baking time may vary depending on the thickness of your chicken breasts. To ensure juicy and tender chicken, use a meat thermometer to check for an internal temperature of 165°F (74°C). Remove the chicken from the oven once it reaches this temperature, allowing it to rest for a few minutes before serving to lock in the juices.
- In addition to the cooking time, the placement of the chicken and veggies in the baking dish also contributes to the overall success of the dish. Make sure to mix it all up well. This way, each bite will have a perfect balance of flavors.
- Lastly, don’t forget to garnish your dish with a sprinkle of fresh herbs, such as parsley or chives, to add a burst of freshness and color. These little touches can elevate the presentation and make your skinny baked chicken in cream sauce with cheese, potatoes, and carrots even more appealing.

Verna this took over an hour to cook. I turned up the heat too. Check your timing and temperature.
Wendy, if you cut the potatoes into large pieces, it usually takes longer to cook. I cut mine small, and with chicken breast, it does not take that long.
I also tried the recipe with the cook time and temp you suggested and my potatoes and vegetables were quite small. Everything was quite firm and seemed to not cook at all.
I’m a little confused. You mention cooking the onion and garlic, but only list the powder version of each in the recipe. Am I missing something? I would love to include an onion and minced fresh garlic rather than the powder! I do apologize if I missed something, which is quite possible, as it’s been a long day. Looking forward to making this! From notes above the recipe:
“Onions and garlic – For me, this is that little extra ingredient that takes a regular casserole to the next level. It is very important that you cook the onion and garlic. Cooking it will add a nice sweet onion flavor. Uncooked will add a raw onion flavor. You can’t really taste the onion because it cooks into the sauce, but you can also omit it.”
That’s right Erica. Raw onions and garlic don’t cook down as well in this recipe as I’d like which is why now I use onion powder and garlic powder.
But, I have used sauteed onions and garlic before which works better.
If you prefer you can replace the onion powder with 1/2 cup sauteed onions and garlic powder with 2 large garlic cloves.
Thanks
