Key Ingredients for Chicken Broccoli Potato Casserole

See recipe card below for full list of measurements, ingredients, and instructions.

Chicken Breast

Lean, diced chicken breast is the protein powerhouse here, making the casserole filling and satisfying. Cut chicken into bite-sized pieces for even cooking and the perfect balance in every bite. Boneless, skinless chicken thighs are a great swap if you want even juicier results.

Yukon Gold Potatoes

These potatoes hold their shape beautifully when baked, soaking up all of that luscious, creamy sauce. Peel them for a classic texture, and cut them into half-inch cubes so they cook through perfectly. Russet potatoes or red potatoes also work well, but the texture may vary slightly.

Broccoli Florets

Fresh broccoli adds a burst of color, nutrition, and a slight crunch. Cut florets into small, uniform pieces so they cook quickly. Both fresh and frozen broccoli work-if using frozen, thaw and pat dry to prevent excess moisture in the casserole.

Cheddar Cheese

Sharp cheddar gives that signature gooey, melty cheese pull. Shred your own cheese for the very best melt and flavor. You can substitute with Monterey Jack, Colby, or a blend for different cheesy notes.

Cream of Chicken Soup

This time-saving shortcut creates an ultra-creamy, savory base. Choose low-sodium for more control over seasoning, or swap in cream of mushroom or celery for a twist. For a homemade version, combine a simple roux with chicken broth and milk.

Chicken Broccoli Potato Casserole cooking process

Instructions for Chicken Broccoli Potato Casserole

See recipe card below for full list of measurements, ingredients, and instructions.

Prep and Preheat

Start by preheating your oven to 400°F (200°C). Lightly grease a 9x13-inch casserole dish with a little olive oil or non-stick spray-this helps prevent sticking and makes serving easier later.

Sauté the Aromatics

In a large skillet over medium heat, drizzle in the olive oil. Toss in the chopped onion and cook for 2-3 minutes, until it turns soft and translucent. Add the minced garlic and cook for 1 minute more, just until fragrant.

Mix the Creamy Sauce

In a large mixing bowl, whisk together the cream of chicken soup, sour cream, milk, smoked paprika, thyme, salt, and pepper. Add 1 cup of the shredded cheddar cheese and stir until well combined. This mixture is the key to that rich, luscious texture.

Combine and Layer

Add the diced chicken, cubed potatoes, sautéed onion and garlic, and broccoli florets to the bowl with the sauce. Stir until everything is thoroughly coated and evenly distributed.

Transfer mixture to your prepared baking dish and spread into an even layer. Sprinkle the remaining 1 cup of cheddar cheese evenly over the top.

For an irresistibly crunchy finish, scatter the panko breadcrumbs over the cheese.

Bake Until Golden and Bubbly

Bake uncovered in the preheated oven for 35-40 minutes, or until the potatoes are fork-tender and the top is golden and bubbling. If you like a crispier top, broil for an additional 2-3 minutes-but keep a close eye so it doesn't burn!

Garnish and Serve

Let the casserole rest for about 5 minutes before serving. Sprinkle with fresh parsley for a colorful, bright finishing touch. Scoop and enjoy the creamy goodness!

Recipe Variations

Spice It Up

Kick up the heat by adding a pinch of crushed red pepper flakes, or stir in a chopped jalapeño to the mix. Pepper jack cheese is a fantastic swap for an extra kick!

Veggie-Loaded Version

Make it even more veggie-forward by adding diced bell peppers, mushrooms, or spinach. Just be sure to chop veggies into small pieces so they cook through evenly.

Make It Gluten-Free

Simply swap the cream of chicken soup for a certified gluten-free variety, and use gluten-free panko or omit the breadcrumbs entirely. Everything else remains just as delicious!

Lighter Option

Substitute light sour cream and reduced-fat cheese, or try Greek yogurt in place of sour cream for a protein boost with fewer calories.

Rotisserie Chicken Shortcut

Got leftover rotisserie chicken? Shred it and fold it in with the potatoes and broccoli. Reduce the initial baking time by about 10 minutes since the chicken is already cooked.

Serving Suggestions

Serve your Chicken Broccoli Potato Casserole with a crisp green salad and a piece of warm, crusty bread for a satisfying, balanced meal. For a refreshing touch, garnish with extra chopped parsley or a sprinkle of chives. This casserole also pairs beautifully with steamed green beans or roasted carrots for even more color and flavor on your plate.

Storage and Reheating

Let leftovers cool, then cover tightly or transfer to an airtight container and refrigerate for up to 4 days. Reheat single portions in the microwave until warmed through, or place the entire casserole (covered with foil) in a 350°F (175°C) oven until hot, about 20 minutes. For best results, add a splash of milk to keep it creamy! This casserole can also be frozen-wrap tightly and freeze for up to 2 months, then thaw overnight in the refrigerator before reheating.

Frequently Asked Questions About Chicken Broccoli Potato Casserole (FAQ)

Q: Can I prepare Chicken Broccoli Potato Casserole ahead of time?

A: Yes! Assemble the casserole up to a day in advance, cover, and refrigerate. When ready to bake, add a few extra minutes to the cook time if it's going straight from the fridge.

Q: Can I use cooked chicken instead of raw?

A: Absolutely. Simply stir in cooked, diced, or shredded chicken and reduce the baking time by about 10 minutes since the chicken only needs to be heated through.

Q: What’s the best way to make this casserole even creamier?

A: For extra creaminess, add 4 oz softened cream cheese to the sauce, or swap sour cream for Greek yogurt for a rich, tangy layer.
