Easy Low Carb Chicken Casserole: Simple and Irresistible
Ingredients
Method
- Preheat your oven to 375°F (190°C).
- In a large mixing bowl, combine the cooked chicken, chopped bacon, broccoli florets (or well-drained thawed spinach), and minced garlic.
- Add the ranch dressing and ranch seasoning mix (if using) to the bowl and mix until all ingredients are evenly coated.
- Stir in 1/2 cup mozzarella cheese and 1/2 cup cheddar cheese.
- Transfer the mixture into a greased baking dish and spread evenly.
- Sprinkle the remaining 1/2 cup mozzarella and 1/2 cup cheddar cheese evenly on top as a topping.
- Bake in the preheated oven for 15-20 minutes, or until the casserole is bubbly and the cheese is melted and golden.
- Remove from oven and let cool for a few minutes before serving.
Notes
- Feel free to swap broccoli for spinach based on preference. Leftovers store well in the refrigerator for up to 3 days. Add extra ranch seasoning for more flavor or a pinch of crushed red pepper for heat.

What Makes This Recipe Work
The magic happens when that ranch dressing meets the melted cheese – it creates this incredibly creamy sauce that coats every bite. I learned this trick from my neighbor who swears by ranch in everything, and honestly? She’s not wrong.
The bacon adds just enough smoky saltiness to balance out the creamy elements, while the garlic keeps things from getting too one-note. And here’s the best part – you can prep most of this ahead on Sunday and just pop it in the oven when you’re ready.
| Prep Step | Time Needed | Make-Ahead Tip |
|---|---|---|
| Cook chicken | 15 minutes | Use rotisserie chicken to save time |
| Prep vegetables | 10 minutes | Steam broccoli 2-3 days ahead |
| Assemble casserole | 5 minutes | Can be assembled morning of |
| Bake | 15-20 minutes | Reheat covered at 350°F |
Ingredient Swaps That Actually Work
This recipe is pretty forgiving, which I love because we’ve all been there – missing one ingredient and not wanting to run to the store. The spinach swap is my personal favorite when I want to switch things up, and it makes the whole dish feel a little more grown-up.
Pro Tip: If you’re using frozen spinach instead of broccoli, make sure you squeeze out every drop of water. I’m talking paper-towel-squeeze-until-your-hands-hurt level of dry. Nobody wants a soggy casserole.
| Original Ingredient | Easy Swap | Notes |
|---|---|---|
| Broccoli florets | Frozen spinach (thawed, drained) | Squeeze out all excess water |
| Ranch dressing | Caesar dressing | Adds a tangy twist |
| Cooked chicken breast | Rotisserie chicken | Saves 15 minutes prep time |
| Bacon | Turkey bacon or ham | Use same amount, chop small |
Step-by-Step Assembly
The beauty of this easy low carb chicken casserole is that it’s basically just mixing and baking. No complicated techniques, no fancy equipment – just combine everything and let the oven do the work.
- Preheat your oven to 375°F and lightly grease a 9×13 casserole dish
- Mix the base: In a large bowl, combine chicken, bacon, broccoli (or spinach), and minced garlic
- Add the creamy layer: Stir in ranch dressing, then fold in the first round of mozzarella and cheddar
- Transfer and top: Spread mixture in your prepared dish and sprinkle remaining cheese on top
- Bake uncovered: 15-20 minutes until cheese is melted and just starting to turn golden
Note: If you like extra flavor, sprinkle that optional ranch seasoning mix over the cheese before baking. It adds a little extra zing that’s really nice.
Troubleshooting Common Issues
I’ve made this casserole more times than I can count, and I’ve definitely learned from a few kitchen mishaps along the way. The most common issue? A watery casserole that never quite sets up properly.
- Watery results: Usually means your vegetables had too much moisture – always pat chicken dry and drain spinach thoroughly
- Cheese won’t melt evenly: Make sure your casserole ingredients are at room temperature before baking
- Dry texture: Add an extra splash of ranch dressing to the mixture – it should look almost too saucy before baking
Storage and Reheating Tips
This casserole actually gets better with time – all those flavors meld together overnight in the fridge. I usually make it on Sunday and eat it throughout the week for easy lunches.
For reheating, I cover it with foil and warm it in a 350°F oven until heated through. The microwave works too, but the oven keeps that nice cheese texture on top.
| Storage Method | Duration | Best Reheating Method |
|---|---|---|
| Refrigerator (covered) | 3-4 days | Oven at 350°F, covered with foil |
| Freezer (wrapped well) | 2-3 months | Thaw overnight, then reheat in oven |
| Individual portions | 3-4 days | Microwave 1-2 minutes, stirring halfway |
| Serving Suggestion | Why It Works | Prep Time |
|---|---|---|
| Simple side salad | Cuts through the richness | 5 minutes |
| Roasted asparagus | Adds fresh, bright flavor | 15 minutes |
| Crusty bread (for non-low carb family) | Soaks up that creamy sauce | 0 minutes |
| Cauliflower rice | Keeps it low-carb but filling | 10 |
