Steps To Prepare Chicken Spinach Mushroom Oven Dish
Get Your Baking Dish Ready
Turn your oven on to 375°F and let it heat up while you prepare everything else. Take a 9×13 inch baking dish and rub a little oil or butter around the inside so nothing sticks to the bottom and sides.
Arrange The Chicken
Lay your 6 chicken breasts flat in the baking dish in a single layer, making sure they’re spread out evenly across the bottom.
Add The Vegetables
Scatter your fresh baby spinach and sliced mushrooms right over the chicken.
Don’t worry about being perfectly neat here – just distribute them in a way that feels balanced to you.
Season Everything
Sprinkle Weber Herb and Garlic Seasoning over the top to your taste, then do the same with pepper.
This is where you control the flavors, so use as much or as little as feels right to you.
Make The Creamy Sauce
In a microwave-safe bowl, heat the green onion cream cheese for about 30 to 45 seconds so it softens up.
Take a whisk and blend these ingredients together until smooth:
Once your sauce comes together nicely, pour it over the chicken and vegetables in your baking dish.
Bake The First Round
Cover your baking dish loosely with foil and slide it into the 375°F oven for 20 minutes.
The chicken needs time to cook through and the flavors need to meld together.
Add The Cheese And Finish
Take the dish out of the oven and remove the foil carefully.
Spread 8 oz of shredded mozzarella cheese evenly across the top, then put it back in the oven uncovered for another 10 minutes until the cheese turns golden and bubbly.
Rest Before Serving
Pull the dish out of the oven and let it sit on the counter for about 10 minutes.
This gives everything time to settle and makes plating easier when the time comes.

FAQs
Can I use frozen chicken breasts?
Frozen chicken takes longer to cook through, so thaw them completely before baking. This helps everything cook evenly and keeps the chicken from being dry.
What if I don’t have green onion cream cheese?
Regular cream cheese works fine – just mix it with a little chopped green onion if you have it on hand. The flavor will be slightly different but still delicious.
Should I cook the spinach and mushrooms first?
No need to pre-cook them. They release moisture as they bake and soften nicely in the oven with the chicken and creamy sauce.
Can I use a different type of cheese?
Cheddar, Gruyere, or a blend of cheeses all work well here. Just use the same amount and sprinkle it on at the end like the mozzarella.
How do I know when the chicken is done?
The chicken should reach an internal temperature of 165°F (74°C) at its thickest point. A meat thermometer makes this easy to check.
Can I prep this dish ahead of time?
Assemble everything up to the point of baking, cover it, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time since it starts cold.
Chicken Spinach and Mushroom Oven Dish Recipe
- Total Time: 40 minutes
- Yield: 6 1x
Description
Chicken spinach and mushroom low carb oven dish comes together when you layer tender chicken with wilted greens and earthy mushrooms in a creamy sauce that does all the work for you. Dinner is ready in under an hour, and you can adjust the seasonings to match what tastes good to your family.
Ingredients
Protein:
- 6 thin sliced chicken breasts
- 8 ounces shredded mozzarella cheese
Vegetables and Aromatics:
- 1 large package sliced mushrooms
- 1 small bag fresh baby spinach
- 1 container green onion cream cheese
Cooking Liquids and Seasonings:
- 1/4 cup olive oil
- 1/2 cup chicken broth
- Weber Herb and Garlic Seasoning (to taste)
- Pepper (to taste)
Instructions
- Set your oven to 375°F and coat a 9×13 inch baking dish with cooking spray so nothing sticks during baking.
- Arrange your 6 chicken breasts flat in a single layer across the bottom of the prepared dish.
- Scatter the entire small bag of fresh baby spinach and the large package of sliced mushrooms evenly over your chicken.
- Dust everything with Weber Herb and Garlic Seasoning to taste and finish with pepper to your preference at 375°F.
- Microwave 1 container of green onion cream cheese for about 30 seconds until it softens, then whisk in 1/4 cup olive oil and 1/2 cup chicken broth until the mixture flows smoothly.
- Pour your creamy sauce directly over the chicken, spinach, and mushrooms in the dish.
- Cover your dish loosely with foil and slide it into the 375°F oven for 20 minutes.
- Take off the foil and sprinkle 8 oz of shredded mozzarella cheese across the top at the 20 minute mark.
- Return your dish to the 375°F oven for another 10 minutes until the cheese turns melted and takes on a light golden color.
- Pull the dish from the oven and let it rest on your counter for 10 minutes so everything settles before you serve it.
Notes
- Pound your chicken breasts to an even thickness so they cook uniformly and don’t end up with dry edges while the centers are still undercooked.
- Squeeze excess moisture from your spinach before adding it to the dish, since watery spinach releases liquid during baking and makes the sauce diluted and thin.
- Softening the cream cheese in the microwave for just 20-30 seconds makes whisking in the oil and broth much easier without creating lumps.
- For a keto or stricter low-carb version, swap the mozzarella for full-fat cheddar or gruyere, which have slightly lower carbs and add richer flavor to the creamy sauce.
