Instructions to Make Chicken and Potato Casserole

Making Chicken and Potato Casserole might sound like a project, but trust me—it’s super doable and totally worth it. Follow this step-by-step guide to turn everyday ingredients into a cheesy, comforting masterpiece. Whether you’re a beginner or just looking for a no-fuss dinner, these step-by-step directions will walk you through every part of the process with confidence.

Step 1: Preheat Your Oven and Prep the Dish

Start by preheating your oven to 375°F (190°C). You want your oven hot and ready so everything bakes evenly. While it’s heating up, lightly grease a 9×13 inch baking dish with cooking spray or a little olive oil. This keeps things from sticking and makes clean-up way easier.

Step 2: Sauté the Aromatics

In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil shimmers, add 1 medium diced onion and 3 cloves of minced garlic. Cook for about 5 minutes, stirring occasionally, until the onion becomes translucent and the garlic smells amazing (trust your nose here—it’ll let you know). This sautéed base adds flavor depth to the whole casserole, so don’t rush it.

Step 3: Add and Season the Chicken

Now, add 2 cups of cooked, shredded chicken to the skillet with the onions and garlic. You can use rotisserie chicken, leftover grilled chicken, or even poached chicken—whatever you’ve got on hand. Season with 1 teaspoon dried thyme, 1 teaspoon salt, and ½ teaspoon black pepper. Stir everything together and cook for 2–3 minutes so the flavors meld. This step makes a big difference in taste, so don’t skip it even if your chicken is already cooked.

Step 4: Whisk the Creamy Sauce

In a large mixing bowl, whisk together 1 can (10.5 oz) of cream of chicken soup, 1 cup of milk, and 1 cup of sour cream. Mix until the sauce is completely smooth and lump-free. This creamy trio is what makes the casserole rich, comforting, and totally crave-worthy. For a dairy-free alternative, swap sour cream with a plant-based version and use almond or oat milk—see our healthy substitutions post for more ideas.

Step 5: Layer and Mix the Ingredients

Toss your cubed potatoes (about 6 medium potatoes) into the greased baking dish. Spread them out so they form a nice even layer. Next, spoon the chicken and onion mixture over the potatoes. Then pour the creamy sauce evenly across the top. Finally, add 2 cups of frozen mixed vegetables—things like carrots, peas, green beans, and corn. Use a spatula or large spoon to gently mix everything together right in the baking dish. Don’t over-stir; just enough to make sure everything’s coated and distributed well.

Want to skip peeling potatoes? Try using baby red or Yukon Gold potatoes with the skin on for added texture and nutrition.

Step 6: Cover and Bake

Cover the baking dish with aluminum foil. This traps steam and helps the potatoes cook faster. Bake for 35–40 minutes. This first round of baking softens the potatoes and lets the flavors start marrying (aka working their delicious magic).

Pro tip: You can test the potatoes with a fork before adding cheese—if they’re still super firm, give it another 5–10 minutes before moving on.

Step 7: Add the Cheese and Finish Baking

Remove the foil and sprinkle 2 cups of shredded Colby Jack cheese over the top. Return the dish to the oven, uncovered this time, and bake for another 15–20 minutes. The cheese should melt, bubble, and turn a lovely golden brown. This finishing touch takes the casserole from good to “can I have seconds?”

If you like extra-crispy cheese, you can broil it for the last 2–3 minutes—just keep a close eye on it so it doesn’t burn.

Step 8: Let It Rest and Serve

After removing the casserole from the oven, let it rest on the counter for about 10 minutes. This gives the sauce time to thicken slightly and makes it easier to cut and serve. Sprinkle with fresh chopped parsley for a pop of color and freshness (optional, but pretty).

Pair with a light salad or crusty bread if you like, or just dig in and enjoy a one-dish wonder that’ll satisfy everyone at the table.

What to Serve with Chicken and Potato Casserole

Honestly, this casserole can fly solo. But if you want a little something on the side, go for a crisp green salad with a zesty vinaigrette—it helps cut through the richness. A warm dinner roll or crusty bread is also perfect for mopping up that creamy sauce (because you know you want to). Want more veggies? Steam up some broccoli or roast some Brussels sprouts on the side. You could also serve it with a quick fruit salad to keep things fresh and light. This dish is flexible like your favorite pair of jeans—it pairs with just about anything and still makes you feel good.

Key Tips for Making Chicken and Potato Casserole

1. Parboil the Potatoes (Optional): If you’re short on time, you can microwave or boil the potatoes a bit before baking to speed up the process.
2. Use Rotisserie Chicken: Saves you serious prep time and adds extra flavor.
3. Customize the Veggies: Don’t love peas? Swap them for chopped broccoli or bell peppers. This recipe is forgiving.
4. Shred the Cheese Yourself: Pre-shredded cheese is convenient, but hand-shredded melts way better.
5. Let It Rest: Give it 10 minutes post-bake to settle. This helps the sauce thicken up and makes serving easier.

Storage and Reheating Tips for Chicken and Potato Casserole

This casserole makes great leftovers—arguably even better the next day. Store any extras in an airtight container in the fridge for up to 3 days. When you’re ready to reheat, pop a serving in the microwave in 30-second bursts until hot. For the best texture, reheat in the oven at 350°F until warmed through—about 15–20 minutes. Freezing? You can, but the potatoes might get a little mushy. If you do freeze it, use a freezer-safe container and thaw overnight in the fridge before reheating. It’s great for meal prepping or doubling the recipe and freezing half.

FAQs

Can I use raw chicken?
Not recommended. The timing in this recipe assumes the chicken is already cooked. Raw chicken could throw everything off.

Can I make this ahead of time?
Absolutely. Prep the whole thing, cover, and store it in the fridge. Bake it fresh when you’re ready.

Can I use a different soup?
Sure! Cream of mushroom or cream of celery works well if you want a different twist.

What cheese works best?
Colby Jack is ideal, but cheddar, mozzarella, or a Mexican blend would also be tasty.

Is it gluten-free?
Double-check your cream of chicken soup—many canned soups contain gluten. Choose a certified gluten-free brand if needed.
