Low-Carb Chicken Bacon Spinach Casserole - Creamy, Comforting, and Easy
Ingredients
- Chicken: 4 cups cooked, shredded or cubed (rotisserie works great)
- Bacon: 6–8 slices, cooked crisp and crumbled
- Spinach: 5–6 cups fresh baby spinach (about 5 ounces), roughly chopped
- Onion: 1 small, finely diced
- Garlic: 3 cloves, minced
- Cream cheese: 8 ounces, softened
- Heavy cream: 1/2 cup
- Chicken broth: 1/2 cup (low-sodium preferred)
- Cheese: 1 1/2 cups shredded mozzarella or Monterey Jack, divided
- Parmesan: 1/4 cup grated
- Olive oil or butter: 1–2 tablespoons for sautéing
- Seasonings: 1 teaspoon Italian seasoning, 1/2 teaspoon smoked paprika, 1/2 teaspoon onion powder
- Salt and pepper: To taste
- Optional: Red pepper flakes for heat, lemon zest for brightness
Instructions
- Preheat the oven: Set to 375°F (190°C). Grease a 9x13-inch baking dish.
- Cook the bacon: In a large skillet, cook bacon until crisp. Remove, drain on paper towels, and crumble. Leave about 1 tablespoon bacon fat in the skillet for flavor.
- Sauté aromatics: Add a drizzle of olive oil if needed. Cook the onion over medium heat until softened, 3–4 minutes. Stir in garlic and cook 30 seconds until fragrant.
- Wilt the spinach: Add the spinach and a pinch of salt. Toss until wilted and most moisture evaporates, 2–3 minutes. Remove from heat.
- Make the creamy sauce: In a bowl, whisk cream cheese, heavy cream, and chicken broth until smooth. Stir in Italian seasoning, smoked paprika, onion powder, and a good pinch of salt and pepper. If the cream cheese is stiff, microwave the mixture for 15–20 seconds to loosen.
- Combine the filling: In a large mixing bowl, add chicken, sautéed spinach mixture, half the crumbled bacon, 1 cup shredded cheese, and the Parmesan. Pour in the creamy sauce and mix until everything is evenly coated. Taste and adjust seasoning.
- Assemble: Spread the mixture into the prepared baking dish. Top with the remaining 1/2 cup shredded cheese and the rest of the bacon.
- Bake: Bake uncovered for 18–22 minutes, until the casserole is bubbly and the top is lightly golden. If you like a deeper color, broil for 1–2 minutes at the end, watching closely.
- Rest and serve: Let it rest 5–10 minutes so it sets up. Finish with a squeeze of lemon or a sprinkle of red pepper flakes if desired.

Why This Recipe Works
This recipe balances rich flavors with smart ingredients. The salty crunch of bacon pairs with juicy chicken and earthy spinach, while a creamy sauce ties it all together. Using cream cheese and a little heavy cream creates a thick, velvety texture without flour.
The casserole bakes until bubbly and golden, so you get those irresistible edges and a gooey middle.
It’s also flexible. You can use rotisserie chicken to save time, swap cheeses, or add extra veggies like mushrooms. The whole dish comes together in one pan and one baking dish, making cleanup easy.

What Not to Do
- Don’t add raw, unseasoned chicken: This recipe relies on cooked chicken. Raw chicken will water out and throw off timing.
- Don’t skip wilting the spinach: Raw spinach releases moisture and can make the casserole watery.
- Don’t overseason with salt early: Bacon, Parmesan, and broth add salt. Taste the mixture before adding more.
- Don’t bake it to death: Overbaking dries out the chicken.
Pull it when it’s just bubbling and golden.
- Don’t use pre-shredded cheese exclusively: It’s fine in a pinch, but freshly shredded melts smoother and gives a better texture.
Recipe Variations
- Mushroom twist: Sauté 8 ounces sliced mushrooms with the onions for extra umami.
- Broccoli swap: Replace half the spinach with small broccoli florets. Steam or microwave until crisp-tender before mixing in.
- Ranch-style: Add 1–2 tablespoons ranch seasoning to the sauce and use cheddar for the cheese.
- Jalapeño popper vibe: Stir in 1–2 diced jalapeños (seeded) and use a mix of cheddar and pepper jack.
- Herb-forward: Add fresh chopped parsley and basil after baking for brightness.
- Dairy-light: Swap half the cream cheese for whole-milk Greek yogurt. Stir yogurt in after the sauce cools slightly to prevent curdling.
- Turkey bacon: Use turkey bacon if you prefer, and add 1 teaspoon olive oil to boost richness.
FAQ
Can I use frozen spinach?
Yes.
Thaw it completely, then squeeze out as much water as possible with a clean towel. Use about 10 ounces and skip the wilting step.
What if I don’t have cream cheese?
Use mascarpone for a similar texture, or blend ricotta with a splash of cream for a lighter sauce. Adjust salt since ricotta can be milder.
How can I make it spicier?
Add red pepper flakes to the sauce, use pepper jack cheese, or stir in a minced jalapeño with the onions.
A dash of hot sauce works too.
Is this gluten-free?
Yes, as written. Always check labels on broth and seasonings to be sure they’re gluten-free.
Can I prep this for meal prep?
Absolutely. Portion into containers after baking and cooling.
It reheats well and holds up for several days in the fridge.
What sides go well with it?
Try a simple green salad, roasted asparagus, or sautéed zucchini. Cauliflower rice or mashed cauliflower also make great low-carb sides.
Can I use thighs instead of breasts?
Yes. Cooked, chopped chicken thighs stay juicy and add more flavor.
Use the same amount called for in the recipe.
How do I prevent a watery casserole?
Wilt and cook off moisture from the spinach, don’t skip the cream cheese base, and avoid covering while baking. Let it rest before serving so the sauce sets.
