Picture this: a dish so hearty it could solve family dinner arguments, so easy it feels like cheating, and so delicious even your picky eater won’t side-eye it. Chicken Potato Broccoli Casserole is the MVP of weeknight meals—minimal effort, maximum flavor, zero pretentiousness. Why spend hours cooking when you can dump, bake, and dominate?
This isn’t just food; it’s a lifestyle upgrade. And if you’re still reading, congrats—you’re about to win dinner.
Why This Recipe Slaps

This casserole is the culinary equivalent of a mic drop. Protein, carbs, and veggies unite in one dish, meaning fewer dishes to wash (you’re welcome). The chicken stays juicy, the potatoes soak up all the cheesy goodness, and the broccoli?
It’s there to make you feel virtuous. Plus, it’s customizable—swap ingredients, tweak flavors, and still end up with a meal that tastes like you tried way harder than you did.
Ingredients You’ll Need
- 2 cups cooked chicken (shredded or diced; rotisserie chicken works great)
- 3 cups potatoes (diced small, unless you enjoy crunchy potatoes)
- 2 cups broccoli florets (fresh or frozen—no one’s judging)
- 1 cup shredded cheddar cheese (because more cheese = more happiness)
- 1/2 cup sour cream (or Greek yogurt if you’re feeling ~fancy~)
- 1/2 cup milk (any kind, but don’t use orange juice)
- 1 tsp garlic powder (the secret weapon)
- Salt and pepper (to taste, unless you enjoy bland food)
How to Make It (Without Messing Up)

- Preheat your oven to 375°F (190°C). Unless you enjoy eating cold casserole, in which case, carry on.
- Toss potatoes, chicken, and broccoli in a greased baking dish. Mix like you mean it.
- In a bowl, whisk sour cream, milk, garlic powder, salt, and pepper. Taste it. Adjust.
Pretend you’re a chef.
- Pour the sauce over the chicken-potato-broccoli mix. Stir until everything’s coated. No dry spots allowed.
- Sprinkle cheese on top. Be generous. This isn’t the time for restraint.
- Bake for 30–35 minutes. Wait until the cheese is bubbly and the potatoes are tender.
Patience is a virtue.
- Let it cool for 5 minutes. Unless you enjoy burning your mouth. We don’t judge.
How to Store It (Because Leftovers Are Life)
Let the casserole cool completely, then store it in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave—just know the microwave will sacrifice some crispiness.
For longer storage, freeze it for up to 2 months. Thaw overnight in the fridge before reheating.
Why This Recipe Is a Win

It’s balanced, filling, and idiot-proof. You get protein from the chicken, fiber from the broccoli, and carbs from the potatoes—all in one dish.
It’s also budget-friendly and perfect for meal prep. Plus, it’s a sneaky way to get veggies into kids (or stubborn adults). Win-win-win.
Common Mistakes to Avoid
- Undercooking the potatoes. Dice them small, or parboil them first.
No one likes crunchy casserole.
- Overloading the dish. If it’s spilling over, you’ve gone too far. Use a bigger dish or less stuff.
- Skipping the cheese. This isn’t the time to be health-conscious. Live a little.
Alternatives (Because Rules Are Made to Be Broken)

Swap chicken for turkey or tofu.
Use cauliflower instead of broccoli. Try sweet potatoes for a twist. Add hot sauce or bacon if you’re feeling extra.
The world is your casserole oyster.
FAQs
Can I use frozen broccoli?
Absolutely. Just thaw and drain it first—unless you want a watery casserole. (Spoiler: You don’t.)
Can I make this ahead of time?
Yes! Assemble it, cover, and refrigerate for up to 24 hours before baking.
Add 5–10 minutes to the bake time if it’s cold from the fridge.
What if I don’t have sour cream?
Greek yogurt works, or use cream cheese thinned with a little milk. FYI, mayo is a divisive choice—proceed with caution.
Is this gluten-free?
Yep, as long as your ingredients are gluten-free. Check labels if you’re using pre-made sauces or seasonings.

This casserole is the dinner hero you didn’t know you needed.
It’s easy, adaptable, and tastes like comfort food without the guilt. Make it once, and it’ll become your go-to. Now go forth and casserole like a boss.
