Creamy Low Carb Chicken Casserole
Equipment
- 9×13 inch casserole dish
- Large mixing bowl
- Pot for boiling
Ingredients
Casserole
- 5 cups broccoli florets fresh or frozen, thawed and drained
- 8 slices cooked bacon chopped into 1/2-inch pieces
- 4 cups cooked chicken shredded or diced into 1/2-inch pieces
- 3 cloves garlic finely minced
- ½ cup shredded mozzarella
- ½ cup shredded cheddar
- 1 cup ranch dressing Hidden Valley Original Ranch preferred
Topping
- ½ cup shredded cheddar Tillamook Medium Cheddar preferred
- ½ cup shredded mozzarella
Instructions
- Preheat oven to 375°F (191°C). If using frozen broccoli, make sure it’s completely thawed and squeeze out all excess water. If using fresh broccoli, boil florets for about 1–2 minutes until they turn bright green, then drain them well.
- In a large mixing bowl, combine cooked chicken, chopped bacon, prepared broccoli, minced garlic, ranch dressing, and both the mozzarella and cheddar cheeses. Mix well until everything is coated in the ranch dressing. Alternatively, you can mix all ingredients directly in the casserole dish to save on dishes.
- Transfer mixture to a 9×13 inch (23×33 cm) casserole dish and spread it out evenly.
- Sprinkle remaining mozzarella and cheddar cheeses evenly over the top for full cheese coverage.
- Bake for about 15 minutes, or until the top is hot, bubbly, and maybe even a little bit golden in spots. Remove from oven and let cool for a few minutes before serving.

How to Make This Creamy Low Carb Chicken Casserole
Okay, let’s get cooking. I promise this is ridiculously easy—if you can stir ingredients in a bowl, you can make this casserole.
Step 1: Prep Your Oven and Veggies
First things first, crank your oven up to 375°F (191°C). While that’s heating up, let’s deal with the broccoli situation. If you’re using frozen broccoli, make sure it’s completely thawed and squeeze out all that excess water—nobody wants a watery casserole. If you’re going the fresh route, just boil your florets for about 1–2 minutes until they turn that gorgeous bright green color, then drain them well.
Pro tip: I like to slightly undercook my broccoli at this stage because it’s going to cook more in the oven. You want it tender-crisp, not mushy.
Step 2: Mix Everything Together (The Fun Part!)
Grab a large mixing bowl and throw in your cooked chicken, chopped bacon, prepared broccoli, minced garlic, ranch dressing, and both the mozzarella and cheddar cheeses. Now just mix it all together until everything’s well combined and coated in that creamy ranch goodness.
Here’s where I’ll share a little secret: you can actually skip the extra bowl and mix everything directly in your casserole dish if you want to save on dishes. I do this all the time when I’m feeling lazy (which is often). Just make sure your casserole dish is big enough to stir comfortably!
Step 3: Get It in the Dish
Transfer your beautiful mixture to a 9×13 inch (23×33 cm) casserole dish and spread it out evenly. This is important—you want an even layer so everything cooks at the same rate and you get cheese in every single bite.
Step 4: The Cheese Topping Moment
This is my favorite part. Sprinkle that remaining mozzarella and cheddar cheese evenly over the top. Don’t be shy here—we want full cheese coverage for maximum golden, bubbly deliciousness.
Step 5: Bake Until Bubbly and Beautiful
Pop your casserole into that preheated oven and let it bake for about 15 minutes, or until the top is hot, bubbly, and maybe even a little bit golden in spots. Your kitchen is going to smell incredible right now.
Once it’s done, let it cool for just a few minutes before diving in. I know it’s tempting to eat it immediately (trust me, I get it), but those extra few minutes let everything set up nicely and prevent you from burning the roof of your mouth. Speaking from experience here.
Expert Tips to Make This Even Better
Chicken Shortcuts That’ll Save Your Life
The biggest time-saver? Buy a rotisserie chicken from your grocery store. I do this probably 90% of the time because who has time to cook chicken from scratch on a Tuesday? Just shred it up and you’re golden. You can also use leftover chicken from pretty much any other recipe—check out my sticky chicken rice bowls recipe for another great way to prep chicken ahead of time.
Bacon Tips for Maximum Crispiness
I always cook my bacon until it’s nice and crispy before adding it to the casserole. Nobody wants chewy bacon (okay, maybe some people do, but I’m not one of them). You can cook it in a skillet, in the oven, or even use pre-cooked bacon if you’re really in a time crunch.
Ranch Dressing Variations
While I’m a Hidden Valley purist for this recipe, you can totally use homemade ranch if that’s your thing. Some people even add an extra tablespoon or two of ranch seasoning mix to amp up the flavor. I’ve tried it both ways and honestly? Both are delicious.
Make It Even Lower Carb
This recipe is already pretty low in carbs, but if you’re really watching your macros, you can use a keto-friendly ranch dressing and make sure you’re using full-fat cheeses. The net carbs per serving are already pretty minimal, which makes this perfect for keto or low carb diets.
Tasty Variations to Keep Things Interesting
Switch Up the Veggies
While I love broccoli in this (it’s classic for a reason!), you can totally swap it out or mix it up. Cauliflower works beautifully, or you could do a combo of both. I’ve even made this with spinach when that’s what I had on hand—just make sure to squeeze out all the liquid like your life depends on it. For more healthy chicken and broccoli inspiration, this is honestly one of my go-to low carb chicken recipes for dinner casseroles.
Cheese Adventures
Feel free to experiment with different cheese combinations. Monterey Jack, Colby Jack, pepper jack for some heat—they all work great. I’ve even thrown in a little cream cheese before for extra creaminess, which was a total win.
Protein Swaps
This recipe works with turkey too! Leftover turkey from the holidays? Perfect use for it. You could even try it with shredded pork if you’re feeling adventurous.
Add Some Heat
If you like things spicy, add some diced jalapeños, a sprinkle of red pepper flakes, or use pepper jack cheese in the mix. I sometimes drizzle a little hot sauce over my portion because I like to live dangerously.
Troubleshooting Common Issues
My Casserole Is Watery—Help!
This usually happens when the broccoli or chicken wasn’t dried properly before mixing. Make sure you’re squeezing out all excess moisture from your veggies and letting your cooked chicken cool and drain if it’s especially juicy. If you notice liquid pooling while it bakes, just carefully drain it off or let it bake a few extra minutes to evaporate.
The Top Isn’t Getting Golden
If your cheese isn’t browning the way you want, just pop it under the broiler for the last 2–3 minutes. Keep a close eye on it though—broilers are basically fire-breathing dragons and things can go from perfect to burnt in about 30 seconds.
It’s Too Dry
This usually means you didn’t use enough ranch dressing or you overbaked it. Make sure you’re measuring that ranch correctly, and check your casserole around the 12-minute mark if you have a hotter oven. You can always add an extra 1/4 cup of ranch to the mix if you like things extra creamy.
Storage and Reheating Like a Pro
| Storage Method | How Long It Lasts | Best Practices |
|---|---|---|
| Refrigerator | 4–5 days | Store in an airtight container. Let it cool completely first to prevent condensation |
| Freezer | Up to 3 months | Use a freezer-safe container. Label with the date because future you will forget |
| Reheating | Until hot throughout | Microwave individual portions for 2–3 minutes, or reheat in the oven at 350°F for 15–20 minutes |
No-Waste Kitchen Ideas
Got leftovers? (Lucky you!) This reheats beautifully, which makes it perfect for meal prep. I like to portion it out into individual containers for quick work lunches. You can also chop up leftovers and use them as a filling for low carb wraps or stuff them into bell peppers for a fun twist.
The leftover bacon (if there is any—bacon has a way of disappearing in my house) can be saved for my chickpea feta avocado salad or crumbled over pretty much anything. Same with the extra cheese—I mean, when is extra cheese ever a problem?

Creamy Low Carb Chicken Casserole FAQs
Can I make this casserole ahead of time?
Absolutely! You can assemble the entire thing up to 24 hours in advance, cover it tightly with foil or plastic wrap, and keep it in the fridge. When you’re ready to bake, just pop it in the oven (you might need to add 5 extra minutes since it’s starting cold). This is perfect for those nights when you need dinner basically ready to go.
What’s the best way to cook chicken for this recipe?
Honestly, the easiest way is to grab a rotisserie chicken from the store—no judgment here. But if you want to cook it yourself, you can bake chicken breasts at 375°F for about 25–30 minutes, boil them for 15–20 minutes, or even use an Instant Pot (8 minutes on high pressure). For more chicken dinner ideas, my easy garlic parmesan chicken pasta recipe has great tips for cooking chicken perfectly every time.
Can I use a different type of dressing instead of ranch?
Sure! Caesar dressing works really well, and I’ve even tried it with a creamy Italian dressing. The flavor profile changes, but it’s still delicious. Ranch is classic for a reason though, and it’s what gives this casserole that signature creamy, tangy flavor that everyone loves.
Is this recipe keto-friendly?
Yes! With only about 4g net carbs per serving, this fits perfectly into most keto meal plans. Just make sure you’re using a keto-friendly ranch dressing (check the label for added sugars) and full-fat cheeses. If you’re looking for more keto-friendly dinner options, check out my white chicken chili—it’s another low carb winner.
How do I know when the casserole is done?
You’re looking for the top to be bubbly and hot throughout. The cheese should be melted and maybe just starting to get golden in spots. If you stick a knife or fork in the center, it should come out hot. Since everything going into the casserole is already cooked, you’re really just heating it through and melting the cheese, so there’s not much risk of undercooking.
