Ingredients You’ll Need
One of the joys of making this dish is how a handful of quality, familiar ingredients come together to create something so indulgent yet so, so easy. Each component does its part: bringing bold flavor, irresistible texture, and a pop of color to the Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe. Here’s what you’ll need and why:
- Thin-sliced chicken breasts (6): These cook evenly and soak up all the fabulous flavors; plus, having them thin-sliced keeps things tender and juicy.
- Green onion cream cheese (1 container, 8 oz): This adds a savory, herby creaminess that binds the whole dish together and adds a pop of mild onion flavor.
- Olive oil (¼ cup): A splash in both the sauce and for sautéing mushrooms because its richness brings velvety texture and depth.
- Chicken broth (½ cup): Adds moisture and amplifies that savory undertone that takes every bite over the top.
- Sliced mushrooms (1 large package): Earthy, meaty, and full of umami, mushrooms elevate the heartiness of this low-carb meal.
- Fresh baby spinach (1 small bag): Adds color, freshness, and essential nutrients—no wilted greens here!
- Weber Herb and Garlic Seasoning (1 dash): A quick sprinkle brings all the herbs and garlic flavors you crave, transforming the chicken into something special.
- Shredded mozzarella cheese (8 oz): Melts beautifully for that irresistible, bubbly golden crust.
How to Make Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe
Step 1: Prep and Layer the Chicken
Start by preheating your oven to 375°F (190°C). Lay the thin-sliced chicken breasts in a single layer in a 13×9-inch baking dish. Sprinkle them with salt, pepper, and a dash of Weber Herb and Garlic Seasoning. Getting this initial layer right is crucial—the seasoning infuses the meat with big, bold flavor and keeps every bite memorable.
Step 2: Sauté the Mushrooms
Grab a skillet and add just a bit of olive oil. Toss in your sliced mushrooms and sauté until they’re softened and juicy. This step is worth the extra pan; it brings out their deep, savory flavor and ensures they don’t leave the whole dish watery. Once done, spread those glorious mushrooms evenly over the chicken in the baking dish, then scatter the fresh spinach right on top. The heat from the oven will wilt them just the right amount!
Step 3: Whip Up the Creamy Sauce
In a bowl, mix together the green onion cream cheese, chicken broth, and olive oil. If the cream cheese is a little stiff, let it sit out for a few minutes or give it a gentle zap in the microwave. Stir it until smooth and luxurious—this will be your flavor-packed sauce. Pour it generously over your chicken, mushrooms, and spinach, letting it seep into all the nooks and corners.
Step 4: Bake Covered
Cover your baking dish loosely with foil (don’t seal it!) and slide it into the preheated oven for 20 minutes. Covering keeps the moisture in so everything cooks evenly and the chicken stays juicy, while that little gap in the foil helps prevent things from getting soggy.
Step 5: Uncover and Continue Baking
After 20 minutes, remove the foil. Let the dish bake for another 20 minutes uncovered. This gives the sauce a chance to thicken up and allows the top to start browning ever so slightly. You’ll notice the kitchen filling with irresistible aromas about now!
Step 6: Add Cheese and Finish Baking
Now for the grand finale: sprinkle the shredded mozzarella evenly over everything (don’t skimp!). Return the dish to the oven for 5-10 minutes, just until the cheese is melted and bubbly with a bit of golden color. It’s pure cheesy perfection that brings the Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe together in one showstopping finish. Serve it hot and dive right in!
How to Serve Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe

Garnishes
A sprinkle of fresh chopped parsley or chives looks stunning against the golden cheese crust and adds a welcome burst of freshness. If you’re feeling fancy, a crack of black pepper or a dusting of extra parmesan pairs beautifully with the flavors in this Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe.
Side Dishes
This is a complete meal on its own, but if you want to round it out, consider a bright salad with a simple vinaigrette or some quickly sautéed green beans. Cauliflower rice is also a favorite for soaking up extra cream sauce while keeping things low-carb and light.
Creative Ways to Present
For a more elegant presentation, serve individual portions in shallow bowls with a little extra sauce ladled over the top. Or, plate it family-style in the center of your table straight from the baking dish. Don’t hesitate to add roasted cherry tomatoes or thin lemon slices to the platter for an extra pop of color—this Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe always looks (and tastes) restaurant-worthy!
Make Ahead and Storage
Storing Leftovers
If you end up with leftovers, lucky you! Simply let the Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe cool to room temperature, then transfer portions to an airtight container. It’ll keep happily in the fridge for up to three days, making for a next-day lunch you’ll actually look forward to.
Freezing
You can freeze this dish, too! Once cooled, package individual portions or the whole lot in freezer-safe containers. For best results, freeze before adding the mozzarella topping; add the cheese fresh just before reheating in the oven after thawing. It’s a wonderful freezer meal that maintains its flavor and texture.
Reheating
Reheat your leftovers gently in the microwave (loosely covered to prevent drying out) or the oven at 350°F until warmed through. Add a splash of broth or a drizzle of olive oil if needed to keep everything nice and saucy—the chicken stays tender and that cheesy topping revives beautifully!
FAQs
Can I use a different type of cheese?
Absolutely! While mozzarella creates that luscious melted topping, feel free to swap in provolone, gouda, or even a little bit of shredded parmesan for extra bite. Just keep the melt factor in mind for best results.
What if I don’t have green onion cream cheese?
You can use plain cream cheese and stir in some finely minced green onions or chives for a similar effect. Herb or garlic-flavored cream cheese also works great if you want to experiment with different flavor nuances.
Can I make this recipe ahead of time?
Definitely! You can assemble the Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe up to one day in advance, keep it covered in the fridge, and bake it just before serving. Just add a couple extra minutes to the first round of baking since it will be starting from cold.
Are there any ways to reduce fat or calories in this dish?
For an even lighter version, try using reduced-fat cream cheese and part-skim mozzarella. You can also use less olive oil for a lighter cream sauce, though the flavor will be slightly less rich.
Can I add other vegetables or swap out the spinach?
For sure! Feel free to add in chopped zucchini, bell peppers, or swap spinach for kale or Swiss chard. Just keep in mind that heartier greens may need a minute or two of sautéing with the mushrooms before baking to get perfectly tender.
