Can a Creamy Casserole Really Have Under 5 Grams of Net Carbs?

This spinach artichoke chicken casserole combines tender chicken, creamy cheese sauce, garden spinach and tangy artichoke hearts in one dish. It takes about 45 minutes from start to finish, uses basic grocery store ingredients, and fits a keto or low-carb lifestyle without any fuss.
Ingredients for Spinach Artichoke Chicken Casserole
This recipe makes 6 servings. Every ingredient has a job: the chicken brings protein, the cream cheese brings silky richness, the spinach adds earthy color, and the artichokes add a bright, tangy bite.

- 1.5 lb (680 g) boneless, skinless chicken breasts, cut into bite-size pieces
- 2 tbsp olive oil
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tsp garlic powder
- 8 oz (225 g) cream cheese, softened
- 1/2 cup sour cream
- 1/4 cup mayonnaise
- 10 oz (280 g) frozen chopped spinach, thawed and squeezed very dry
- 14 oz (400 g) canned artichoke hearts, drained and chopped
- 3 cloves garlic, minced
- 1 cup shredded mozzarella, divided
- 1/2 cup grated Parmesan, divided
- 1/4 tsp red pepper flakes (optional)
Easy substitutions:
- Chicken thighs work in place of breasts and stay juicier.
- Use Greek yogurt instead of sour cream for extra protein.
- Swap fresh spinach for frozen. Wilt 10 oz in a pan first, then squeeze out the water.
- Try a dairy-free cream cheese and cashew-based cheese for a dairy-free version.
- Choose marinated-free artichoke hearts packed in water to keep carbs and oil in check.
Timing
- Prep time: 15 minutes
- Cook time: 30 minutes
- Total time: 45 minutes
That is about 25% faster than the typical 60-minute chicken casserole. The cut-up chicken cooks quickly and the sauce comes together in one bowl, so this spinach artichoke chicken bake is realistic for a busy weeknight.
Step-by-Step Instructions
Here is how to make your spinach artichoke chicken casserole from start to finish.
Step 1: Preheat and Prep
Heat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. Tip: set out the cream cheese 30 minutes early so it blends smoothly with no lumps.
Step 2: Season and Sear the Chicken
Toss the chicken pieces with salt, pepper, and garlic powder. Heat the olive oil in a large skillet over medium-high heat and cook the chicken for 4 to 5 minutes until golden on the outside. It does not need to cook through, because it will finish in the oven. Tip: do not crowd the pan, or the chicken will steam instead of brown.
Step 3: Squeeze the Spinach Dry
Place the thawed spinach in a clean kitchen towel and twist hard over the sink. You want it nearly dry.
Tip: This single step is the best way to avoid a watery casserole.

Step 4: Mix the Creamy Sauce
In a large bowl, stir together the cream cheese, sour cream, mayonnaise, minced garlic, half the mozzarella, half the Parmesan, and the red pepper flakes. Fold in the spinach and chopped artichoke hearts until everything is evenly coated.
Step 5: Combine and Assemble
Add the seared chicken to the bowl and stir gently. Spread the mixture evenly in your baking dish.
Tip: Press it down lightly so the top layer of cheese melts evenly.
Step 6: Add the Cheese Topping
Sprinkle the remaining mozzarella and Parmesan over the top. For extra flavor, add a pinch of paprika or Italian seasoning.
Step 7: Bake Until Bubbly
Bake uncovered for 25 to 30 minutes, until the edges bubble and the cheese turns golden. The chicken should reach an internal temperature of 165°F (74°C). Broil for 2 minutes at the end if you like a browned top.
Step 8: Rest Before Serving
Let the dish rest for 5 minutes. This lets the sauce thicken so each scoop holds together on the plate.

Common Mistakes to Avoid
- Leaving the spinach wet. Extra water thins the sauce. Squeeze it until almost no liquid comes out.
- Overcooking the chicken. Chicken breast dries out fast. Sear it briefly and let the oven finish the job.
- Using cold cream cheese. It will not blend smoothly. Soften it first.
- Skipping the rest time. Cutting right away leaves a runny casserole.
- Using marinated artichokes. They add oil, sugar and strong flavor that can throw off the balance of your spinach artichoke chicken casserole.
- Using pre-shredded cheese only. It contains anti-caking starch that can melt unevenly. Freshly grated Parmesan melts better.
Storing Tips for the Recipe
- Refrigerator: Cool the spinach artichoke chicken casserole, cover tightly, and store for up to 4 days.
- Freezer: Freeze in a sealed container for up to 3 months. Thaw overnight in the fridge.
- Reheating: Warm in a 350°F (175°C) oven for 15 to 20 minutes, or microwave single portions for 1 to 2 minutes.
- Make ahead: Assemble everything up to 24 hours ahead, cover and refrigerate, then bake when ready. Add 5 extra minutes to the bake time if it goes in cold.
