There’s something about coming home after a long day and slipping into the familiar comfort of a warm casserole. This chicken broccoli casserole mushroom soup creation has that kind of cozy hold—like a gentle hug in food form. I remember one evening, distracted by the glow of the kitchen timer and a half-finished book, I barely noticed the rich aroma filling the house. The bubbling cheese, the faintly earthy mushroom scent, and the crisp, buttery topping all promised something satisfying. It wasn’t fancy, but it was the kind of dinner that makes you slow down and breathe out, even if just for a moment.
It’s not perfect, of course. Sometimes the topping gets a little more golden than I planned, or the broccoli sits somewhere between tender and crisp. But that’s kind of what makes it feel homemade—no one’s rushing, no one’s fussing. Just a dish built from simple ingredients that come together in a way that feels like a warm evening inside, no matter the weather outside.
Why You’ll Love It
- The creamy mushroom soup base keeps things rich without being overwhelming, striking a balance that’s just right.
- Broccoli adds a fresh pop of green and a bit of crunch, but if you’re like me, sometimes it’s a little softer than planned—and that’s okay.
- It’s simple — and that’s kind of the point. No complicated steps, just a kind of comforting ease that’s hard to resist.
- The crispy cracker topping adds a buttery crunch that contrasts perfectly with the gooey cheese underneath.
If you’re feeling a little hesitant about casseroles, this one is forgiving. It’s the kind of recipe that welcomes small tweaks and the odd distracted moment, and still turns out delicious.
PrintChicken Broccoli Casserole with Mushroom Soup

- Prep Time: 15 minutes
- Cook Time: 40 minutes
- Total Time: 55 minutes
- Yield: 6
Ingredients
3 cups cooked chicken, shredded or diced
4 cups fresh broccoli florets
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup sour cream
1/2 cup mayonnaise
1 cup shredded cheddar cheese
1/2 cup shredded mozzarella cheese
1/2 cup chopped onion
2 cloves garlic, minced
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 teaspoon dried thyme
1 cup crushed buttery crackers (such as Ritz)
2 tablespoons unsalted butter, melted
Instructions
Preheat the oven to 350°F (175°C).
Steam the broccoli florets until just tender, about 4-5 minutes. Drain and set aside.
In a large mixing bowl, combine the cream of mushroom soup, sour cream, mayonnaise, salt, black pepper, dried thyme, minced garlic, and chopped onion. Mix well until smooth.
Add the cooked chicken, steamed broccoli, shredded cheddar cheese, and shredded mozzarella cheese to the bowl. Stir until all ingredients are evenly coated with the sauce mixture.
Transfer the mixture into a greased 9×13-inch baking dish and spread evenly.
In a small bowl, mix the crushed buttery crackers with the melted butter until the crumbs are evenly coated.
Sprinkle the cracker mixture evenly over the casserole.
Bake uncovered in the preheated oven for 35-40 minutes, or until the casserole is bubbly and the topping is golden brown.
Remove from the oven and let it rest for 5 minutes before serving.
Kitchen Notes: I usually make this in a modest baking dish—nothing fancy, just something sturdy enough to go from oven to table. I like to serve it with a simple side salad or some crusty bread to soak up any extra sauce. Sometimes I swap the cheddar for a sharper cheese if I’m feeling bold, or leave out the mayo because I forgot to buy it once (and honestly, it still turned out great). If you want a slightly lighter version, swapping sour cream for Greek yogurt can work, but I haven’t tested it extensively. This casserole feels at home on any night you want something hearty without a fuss.
FAQ
Can I use frozen broccoli? You can, but I recommend thawing and draining it well to avoid extra moisture making the casserole watery.
What if I don’t have condensed mushroom soup? You can try making a quick homemade mushroom sauce or substitute with cream of chicken, though the flavor will shift slightly.
Can this be made ahead? Yes, you can assemble it a day before and bake when ready, but the topping is best added right before baking to keep it crisp.
