Key Ingredients:
Thin-Sliced Chicken Breasts: I like to use thin-sliced chicken breasts because it makes it easy to cook through quickly and evenly in the oven. If you have only regular chicken breasts, you can slice them horizontally or pound them with a meat mallet to the same thickness.
Green Onion Cream Cheese: Adds flavor to the creamy sauce. If you can’t find it, use regular cream cheese and stir in some chopped green onions or chives.
Baby Spinach: Fresh baby spinach works the best here as it wilts nice and doesn’t get too soggy in the oven. Frozen spinach, thawed and squeezed to remove excess water, works, too.
Mushrooms: Pre-sliced mushrooms are a time-saver, but you can use whole mushrooms, slicing them to your desired thickness. White button mushrooms or cremini mushrooms would both be great in here.
Weber Herb and Garlic Seasoning: using a great herby and garlic seasoning for this dish. If you don’t have it, use a blend of garlic powder, Italian seasoning or your favorite herb blend.
Shredded Mozzarella Cheese: Mozzarella makes for a creamy, melty top layer. If you want a flavor twist, add a blend of mozzarella and Parmesan or Gruyère.

Serving Suggestions:
While this dish is satisfying enough to eat alone, here are some suggestions for pairings, to turn it into a feast:
Cauliflower Rice: If a low-carb alternative is more your speed, add cauliflower rice, which absorbs all that creamy sauce.
Zucchini Noodles: This light and bright zoodles dish juxtaposes is the counterpoint to the rich, meaty sauce.
Side Salad: It’s a pleasurable relief to have a simple mixed greens salad with a quick vinaigrette.
Roasted vegetables: Roasted broccoli or asparagus for extra color, nutrients.
Storage and Reheating Tips:
It stores and reheats well, so it’s a wonderful make-ahead or leftover meal.
Store any leftover in an airtight container in the refrigerator for up to 3 days.
Freezing: Allow the dish to cool completely before measuring and packaging it into freezer-safe containers. Freeze for up to 2 months. Defrost in the refrigerator overnight, then heat.
To Reheat: Reheat in the oven at 350°F (175°C) for 10 to 15 minutes, or until heated through. Or microwave in single portions at medium heat in 1-minute intervals, until hot.
Recipe Variations:
Sun-Dried Tomatoes: Toss in some chopped sun-dried tomatoes for a tangy, sweetish flavor.
Keto version: Use a low-carb marinara sauce instead of the chicken broth to make the sauce heartier without adding extra carbs.
Cheese Swap: Use a combo of nutty cheeses, like Gruyère or Swiss, instead of mozzarella; or a combo of cheddar and Monterey Jack for extra creaminess.
Italian Twist: Stir in fresh basil and Italian seasoning for a more Italian-inspired version of this bake.
With artichokes: For a distinctive tang to the spinach and mushrooms, you can stir in a drained can of chopped artichoke hearts.

A creamy, comforting meal that’s low carb and wraps you up.
