Ingredients You’ll Need
Getting the ingredients right is key to making this low-carb dinner shine. Each one brings something special—texture, brightness, or richness—that elevates the final dish without complicating the cooking.
- Chicken breasts: Using large pieces cut into bite-sized chunks ensures quick, even cooking and a tender bite.

- Mushrooms: Their natural umami deepens the flavor profile and gives the dish satisfying substance.
- Shredded mozzarella cheese: Melts beautifully to create that irresistible gooey top layer.
- Grated Parmesan cheese: Sprinkled on top, it gives a nutty, savory finish and an inviting golden crust.
- Heavy cream: Brings luscious creaminess that ties all the ingredients together.
- Garlic: Infuses the dish with aromatic warmth and depth.
- Onion: Adds a subtle sweetness and body when sautéed.

- Salt and pepper: Essential for balancing and enhancing the natural flavors.
How to Make Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe
Step 1: Preheat and Prepare the Oven
Start by getting your oven ready at 375°F (190°C). Preheating is important as it helps the dish cook evenly and develop that delightful golden cheese crust we all look forward to.
Step 2: Sauté the Aromatics
Heat the olive oil in a large skillet over medium heat. Toss in the finely chopped onion and minced garlic. Cook them gently until they’re translucent and releasing their irresistible fragrance, about 3 to 4 minutes. This base infuses the entire dish with welcoming warmth.
Step 3: Cook the Mushrooms
Add the sliced mushrooms to your skillet and let them sauté for 5 to 6 minutes. Keep stirring occasionally until they soften and brown slightly—this caramelization adds a wonderful depth of flavor that complements the mild chicken beautifully.
Step 4: Wilt the Spinach
Next, stir in the chopped fresh spinach. It will quickly wilt down within about 2 minutes, shrinking considerably and mixing seamlessly with your mushrooms and aromatics. Once combined, remove the skillet from heat to maintain those vibrant green hues and fresh taste.
Step 5: Combine Chicken and Veggies
In a large mixing bowl, bring together the bite-sized chicken pieces and your sautéed vegetable mixture. Sprinkle in the dried oregano, thyme, salt, and pepper. Toss gently so every morsel is seasoned, setting the stage for the creamy delight to come.
Step 6: Add Cream and Cheese
Pour in the heavy cream along with half of the shredded mozzarella cheese. Stir carefully until every ingredient is coated in the creamy blend, ensuring the final baked dish will be juicy and packed with cheesy goodness.
Step 7: Transfer to Baking Dish
Grease your baking dish to prevent sticking, then transfer the creamy chicken and vegetable mixture evenly inside. Spread it out gently so it bakes uniformly.
Step 8: Top with Cheese and Bake
Sprinkle the remaining mozzarella and the grated Parmesan cheese evenly over the top. This layer will melt into a bubbly, golden crust as it bakes. Place the dish in the oven and bake uncovered for 25 to 30 minutes. The chicken should be cooked through and the cheese irresistibly browned.
Step 9: Let It Rest Before Serving
When your oven timer dings, pull out the dish and allow it to cool for a few minutes. This resting time lets everything settle, making each portion easier to serve and ensuring the flavors meld beautifully.
How to Serve Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe

Garnishes
A sprinkle of freshly chopped parsley or basil lifts the dish with a burst of color and fresh herbal brightness. A few red pepper flakes add just the right amount of spice if you like a little kick.
Side Dishes
This low-carb wonder pairs wonderfully with simple sides like roasted cauliflower rice, crisp green salads, or buttery sautéed zucchini noodles. These keep the meal light while complementing the rich textures and creamy flavors.
Creative Ways to Present
For a casual gathering, serve this dish straight from the baking dish to keep it warm and inviting. Or, plate it with a lemon wedge on the side to add a zesty twist at the last minute. For a more elegant approach, serve portions in small ramekins with a drizzle of olive oil and a sprinkle of extra Parmesan on top.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (which might be tough), store them in an airtight container in the refrigerator for up to 3 days. The flavors often deepen overnight, making the next-day meal just as delightful.
Freezing
This Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe freezes well. Let it cool completely, then transfer to a freezer-safe container. It can be frozen for up to 2 months. Thaw in the refrigerator overnight before reheating.
Reheating
Reheat leftovers gently in the oven at 350°F (175°C) for about 15-20 minutes or until heated through. To keep the topping from drying out, cover the dish loosely with foil. You can also microwave individual servings, but the oven method helps retain that lovely baked cheese texture.
