Ingredients You’ll Need

Here’s the beautiful part about the Chicken, Spinach, and Mushroom Low-Carb Oven Dish — the ingredient list is refreshingly short but each item brings something special to the table. This line-up delivers serious flavor, a gorgeous meld of colors, and creamy satisfaction all in one pan.

• Chicken breasts (6, thin-sliced): Choose boneless, skinless pieces for quick cooking and lean, juicy bites in every forkful.
• Fresh baby spinach (1 small bag): Adds a burst of color, tender texture, and soaks up those wonderful oven juices.
• Sliced mushrooms (1 large package): Pick your favorite variety for earthiness and extra moisture as they roast.
• Shredded mozzarella cheese (8 oz): Brings ooey-gooey melt and a golden top, sealing in flavor while adding richness.
• Green onion cream cheese (1 container): The secret to ultra-smooth sauce with a tangy, herby kick that ties everything together.
• Olive oil (1/4 cup): For velvety sauce texture, added flavor and that signature Italian undertone.
• Chicken broth (1/2 cup): Lends depth, juiciness, and helps meld the creamy layers.
• Pepper (dash): A little heat to lift the richness and perk up all the flavors.
• Herb and garlic seasoning (dash): Essential for that aromatic, craveable, classic roast flavor.

How to Make Chicken, Spinach, and Mushroom Low-Carb Oven Dish

Step 1: Prepare the Chicken and Vegetables

Start by preheating your oven to 375°F (190°C), so everything bakes at just the right temperature. Lay those beautiful thin chicken breasts in a single, even layer in your 9×13-inch baking dish — you want every bite to have its own cozy spot. Next, take generous handfuls of fresh baby spinach and layer it over the chicken, followed by an even scatter of sliced mushrooms. These layers not only add flavor but also keep the chicken exceptionally moist as it bakes.

Step 2: Season the Dish

Sprinkle a dash of pepper plus your favorite herb and garlic seasoning evenly over the veggies. This easy touch infuses the whole dish with that familiar savory warmth, making every ingredient shine and ensuring each bite of the Chicken, Spinach, and Mushroom Low-Carb Oven Dish bursts with flavor.

Step 3: Make the Creamy Sauce

Set your green onion cream cheese out for a few minutes to come to room temperature — it makes it so much easier to mix. Whisk together the softened cream cheese, olive oil, and chicken broth in a medium bowl until silky smooth. This lush sauce is your creamy magic trick, combining tang, richness, and just the right amount of savor.

Step 4: Assemble and Bake

Pour the velvety sauce over the dish, letting it sink into every corner and coat the chicken and veggies. Drape a piece of foil loosely over the top (don’t seal it tight), which helps the dish stay juicy while allowing some air to circulate for perfect texture.

Step 5: Bake in Stages

Pop your Chicken, Spinach, and Mushroom Low-Carb Oven Dish into the oven and bake covered for 20 minutes. Then, remove the foil and let it go another 20 to 25 minutes uncovered. This two-step approach gives you heavenly tender chicken with bubbling edges. Now for the best part: sprinkle mozzarella cheese generously over the top, and bake uncovered for another 10 minutes until it’s golden and irresistibly melty.

Step 6: Rest and Serve

It’s tempting to dig in right away, but let the dish stand for about 10 minutes once out of the oven. This gives the sauce time to thicken and helps all those layers settle, so every slice holds together beautifully on your plate.

How to Serve Chicken, Spinach, and Mushroom Low-Carb Oven Dish

Garnishes

A sprinkle of fresh chopped parsley or chives right before serving adds a pop of color and a fresh finish that contrasts perfectly with the creamy, cheesy topping. If you love heat, a touch of red pepper flakes can liven things up. The right garnish is your easy trick to make the Chicken, Spinach, and Mushroom Low-Carb Oven Dish look like a restaurant-worthy showstopper.

Side Dishes

Since this bake is already bursting with flavor, I love pairing it with simple sides like a crisp green salad, zucchini noodles, or roasted cauliflower. These keep things light and let the richness of the main dish really shine. If you’re feeding a crowd or just want to stretch the meal further, a slice of toasted low-carb bread is perfect for sopping up every drop of that cheesy sauce.

Creative Ways to Present

If you want to make this dish a star attraction, try serving it in individual ramekins for an elegant touch. Or layer it over sautéed spiralized zucchini or spaghetti squash for a fun, veggie-forward twist. Either way, the Chicken, Spinach, and Mushroom Low-Carb Oven Dish adapts to whatever mood — or guests — you have at the table.

Make Ahead and Storage

Storing Leftovers

Leftover Chicken, Spinach, and Mushroom Low-Carb Oven Dish keeps beautifully in the fridge for up to three days. Store portions in airtight containers to maintain that freshly baked taste, and you’ll have a ready-to-go high-protein meal for busy days.

Freezing

Yes, you can absolutely freeze this dish! For best results, let the bake cool completely, divide it into portions, and wrap tightly or move to freezer-safe containers. The creamy sauce will maintain its texture when reheated, making this an excellent meal-prep option.

Reheating

To reheat, simply use the oven or microwave. If baking, cover loosely with foil and warm at 350°F (175°C) until heated through. For microwave reheating, use medium power and heat in short bursts, stirring in between if possible, to preserve that creamy, gooey texture.

FAQs

Can I use frozen spinach or mushrooms?

Frozen spinach or mushrooms can be used in a pinch, but make sure you thaw and drain them thoroughly to avoid excess moisture in your Chicken, Spinach, and Mushroom Low-Carb Oven Dish. Fresh provides the best texture and flavor, but don’t let frozen options stop you from enjoying this meal!

Is there a dairy-free substitute for the cream cheese and mozzarella?

Absolutely! There are excellent plant-based cream cheese and shredded mozzarella alternatives available at most supermarkets. Simply swap in your favorite brands for a dairy-free version, and follow the rest of the recipe as written.

Can I make the Chicken, Spinach, and Mushroom Low-Carb Oven Dish ahead of time?

Yes! You can assemble everything (except the final mozzarella topping) up to 24 hours in advance. Keep it covered in the refrigerator, and when you’re ready to bake, let it stand at room temperature for about 20 minutes before popping it in the oven. Add the cheese in the last 10 minutes, as usual.

What other cheeses can I use instead of mozzarella?

Feel free to try provolone, Monterey Jack, or even fontina for new flavor twists. Each will give a different character to your Chicken, Spinach, and Mushroom Low-Carb Oven Dish, so pick your favorite or mix a few for extra depth.

Can I use thighs instead of breasts?

Yes! If you prefer, boneless, skinless chicken thighs work just as well and bring extra richness to the dish. Just be sure to trim any excess fat and lay them flat in the baking dish for even cooking.
