Ingredients You’ll Need
For the casserole:
- 4 cups diced or shredded cooked chicken breast
- 8 slices cooked and chopped bacon
- 5 cups broccoli florets or 1 pound thawed frozen spinach (well-drained)
- 3 cloves minced garlic
- 1 cup ranch dressing
- ½ cup shredded mozzarella cheese
- ½ cup shredded cheddar cheese
For the topping:
- ½ cup shredded mozzarella cheese
- ½ cup shredded cheddar cheese
Optional:
- 1–3 teaspoons ranch seasoning mix (for extra punch)
How To Make Low Carb Chicken Casserole
1. Prep Your Veggies
Preheat your oven to 375°F (191°C). This gives your casserole the cozy, golden top we all love.
- Using spinach? Thaw completely and squeeze out all the water. (Your casserole shouldn’t swim!)
- Using broccoli? Boil florets for 1–2 minutes until bright green, then drain.
Pro Tip: I love using broccoli for extra crunch, but spinach is perfect if you’re feeling lazy—it requires zero cooking ahead.
2. Mix the Magic Together
Grab a large bowl—or skip it and mix right in your casserole dish (we won’t tell!).
Combine:
- 4 cups chicken
- 8 slices bacon
- Prepped broccoli or spinach
- 3 cloves garlic
- 1 cup ranch dressing
- ½ cup mozzarella
- ½ cup cheddar
Mix until everything is well coated in ranchy, cheesy goodness. Add that optional ranch seasoning here if you like your casserole with a little extra sass.
3. Transfer & Top
Pour your mixture into a 9×13 inch (23×33 cm) casserole dish.
Then sprinkle the remaining mozzarella and cheddar on top for that gooey, golden finish we live for.
4. Bake It to Perfection
Pop it in the oven for 15 minutes, or until the top is bubbly and slightly golden.
Let it cool just a bit (if you can wait), then serve. It’s rich, creamy, and oh-so-satisfying.
Tips for Casserole Success
- Shortcut Queen? Use rotisserie chicken—it cuts prep time in half.
- No bacon? No problem. Swap with turkey bacon or chopped ham.
- Ranch alternatives: Try Caesar or a garlic aioli if you’re feeling wild (and not too carb-conscious).
- Make ahead: This casserole holds up like a champ in the fridge for 3–4 days.
Funny story: I once made this for a family potluck thinking it was just “okay,” and it vanished before the potato salad. Now it’s requested at every gathering—especially by my ranch-loving cousin, who may or may not hoard the leftovers.
