What Makes This Casserole So Good
The secret is ranch dressing. Instead of a can of condensed soup, a cup of ranch does all the work, bringing a creamy base and big herby, tangy flavor with just one ingredient. It is the shortcut that makes this casserole taste like it took far more effort than it did.
Then there is the cheese and bacon. Mozzarella melts into gooey, stretchy strands while sharp cheddar adds bold flavor, and crispy turkey bacon brings a smoky, savory crunch in every bite. Half the cheese goes into the mix and half goes on top, so you get a golden, bubbly layer over a creamy center.
Broccoli keeps it fresh and adds color and nutrients, and draining it well is the one thing that keeps the casserole creamy instead of watery. Since the chicken, bacon, and broccoli are already cooked, the bake is quick, just long enough to melt the cheese and bring everything together.
Optional Pro Tip: Broil for a Golden, Bubbly Top
The recipe below bakes up creamy and delicious as written. If you love a deep golden, bubbly cheese layer on top, turn on the broiler for the last 1 to 3 minutes of cooking. The high heat browns the cheese fast and gives the casserole that irresistible restaurant style finish.
Keep a close eye on it under the broiler, since cheese can go from golden to burnt in seconds. It is a completely optional step, but it adds a little color and a slightly crisp, cheesy edge that makes the dish look as good as it tastes.
Cheesy Chicken and Broccoli Casserole (Easy 30-Minute Dinner)
Tender chicken, broccoli, and crispy turkey bacon in a creamy ranch and cheese sauce, baked until hot and bubbly. A comforting, family sized casserole that comes together in about 30 minutes and feeds eight.
Ingredients
- 5 cups broccoli florets
- 8 slices cooked turkey bacon, chopped into 1/2 inch pieces
- 4 cups cooked chicken, shredded or diced into 1/2 inch pieces
- 3 cloves garlic, finely minced for best flavor
- 1/2 cup shredded mozzarella
- 1/2 cup shredded cheddar
- 1 cup ranch dressing
- 1/2 cup shredded cheddar
- 1/2 cup shredded mozzarella
Instructions
- Preheat the oven to 375 F. If using frozen broccoli, thaw completely and squeeze out the excess water. If using fresh broccoli, boil for 1 to 2 minutes until bright green, then drain.
- In a large bowl, combine the chicken, turkey bacon, prepared broccoli, minced garlic, ranch dressing, and the mozzarella and cheddar cheeses. Mix well.
- Transfer the mixture to a 9 by 13 inch casserole dish.
- Sprinkle the remaining mozzarella and cheddar cheeses evenly over the top.
- Bake for about 15 minutes, or until the top is hot and bubbly. Remove from the oven, let cool slightly, then serve.
Tips for the Best Cheesy Chicken and Broccoli Casserole
- Drain the broccoli really well. This is the key to a creamy, not watery, casserole. Squeeze thawed frozen broccoli dry, or drain blanched fresh broccoli thoroughly.
- Use pre cooked chicken. Rotisserie or leftover cooked chicken makes this come together in minutes, since the recipe uses cooked chicken.
- Cook the bacon crisp first. Crisp, chopped turkey bacon adds the best texture and smoky flavor. Pat it on paper towels before mixing it in.
- Do not overbake. Everything is already cooked, so the casserole only needs about 15 minutes, just long enough to get hot and bubbly. Overbaking can dry it out.
- Let it rest before serving. Give it 5 to 10 minutes out of the oven so it sets and is easier to scoop.
- Optional pro tip: broil the top. For bubbly, golden cheese, broil for the last 1 to 3 minutes and watch it closely.
Variations and Add Ins
This casserole is an easy base that takes well to a few quick swaps depending on what you have on hand.
- Make it heartier. Stir in 2 cups of cooked rice or pasta to turn it into a bigger, family stretching meal.
- Switch the veggies. Cauliflower, asparagus, peas, or bell peppers work well in place of, or alongside, the broccoli.
- Use real bacon. Swap the turkey bacon for crisp, crumbled regular bacon if you prefer.
- Change the cheese. Try Monterey Jack, Colby, or a Mexican blend in place of some of the mozzarella or cheddar.
- Add aromatics. A little diced onion or a sprinkle of green onions adds color and extra flavor.
- Make your own ranch. Use a homemade ranch seasoning mix stirred into sour cream or Greek yogurt for a from scratch version.
How to Store Cheesy Chicken and Broccoli Casserole
Leftovers are easy to love. Store the cooled casserole in an airtight container in the refrigerator for 3 to 4 days. Reheat it in a 350 F oven until hot in the center, or warm individual portions in the microwave.
This casserole also freezes well, baked or unbaked, for up to 3 months. To freeze it unbaked, assemble it, cover it tightly, and freeze. Thaw it overnight in the fridge, then bake covered until hot and bubbly. It is a great make ahead meal for busy weeks.
