What You’ll Need (Ingredient Highlights)

Thin-sliced chicken breasts: They cook faster and stay juicy in the bake.

Green onion cream cheese: Adds tang and smoothness to the sauce.

Fresh mushrooms: Their earthy flavor pairs beautifully with the creamy base.

Fresh baby spinach: Wilts just right and gives a vibrant green touch.

Mozzarella cheese: Melts into a bubbly, golden topping.

Weber Herb & Garlic seasoning: Adds depth with just a pinch.

Pro Tips Before You Start

Use thin chicken breasts for even cooking. If your pieces are thick, consider slicing them in half horizontally.

You can sauté the spinach with mushrooms if you prefer them more wilted.

Let the cream cheese soften before mixing for a smoother sauce.

Loosely cover with foil for steam to escape and avoid soggy texture.

How to Make Chicken Spinach Mushroom Bake

Step 1: Prep and Preheat

Preheat your oven to 375°F (190°C).

Lightly grease a 13×9-inch baking dish.

Step 2: Season the Chicken

Arrange the thin chicken breasts in a single layer.

Sprinkle with salt, pepper, and a generous dash of Weber Herb and Garlic Seasoning.

Step 3: Sauté the Mushrooms

In a skillet over medium heat, add olive oil and cook the sliced mushrooms for about 5 minutes until softened and browned slightly.

Step 4: Add the Spinach

Scatter the fresh spinach over the chicken and mushrooms in the dish.

Step 5: Mix the Sauce

In a small bowl, stir together the green onion cream cheese, chicken broth, and olive oil.

Mix until it forms a smooth, pourable sauce.

Step 6: Pour and Cover

Evenly pour the sauce over everything in the baking dish.

Cover the dish loosely with foil (do not seal tightly).

Step 7: Bake Covered

Place the dish in the oven and bake for 20 minutes.

Step 8: Continue Baking Uncovered

Remove the foil and bake for another 20 minutes, allowing the top to brown slightly.

Step 9: Add Cheese and Finish

Sprinkle the mozzarella cheese on top and return to the oven.

Bake for 5–10 minutes more, until the cheese is melted and bubbly.

Step 10: Serve Hot

Let it rest for a few minutes, then serve warm with rice, pasta, or crusty bread.

What to Serve It With

Creamy mashed potatoes or garlic butter rice

Steamed green beans or roasted broccoli

A fresh garden salad with a tangy vinaigrette

Warm crusty bread to mop up the creamy sauce

Variations / Substitutions

Use boneless chicken thighs for a richer flavor

Swap mozzarella with provolone or fontina

Add a sprinkle of chili flakes for heat

Use zucchini or bell peppers along with the mushrooms

Storage & Leftovers

Let leftovers cool completely, then store in an airtight container in the fridge for up to 3–4 days.

To reheat:
Microwave in short intervals or warm in a covered dish in the oven at 300°F until heated through.

You can freeze leftovers too—just wrap tightly and store for up to 2 months.

FAQs

Can I use frozen spinach instead of fresh?
Yes, just thaw and drain it well before layering to avoid excess moisture.

What can I substitute for green onion cream cheese?
Use plain cream cheese and mix in chopped green onions or chives.

Is this dish low-carb?
Yes! It’s great for low-carb or keto diets, especially served with cauliflower mash or veggie noodles.

Can I make this ahead?

Add cheese just before the final bake.

Can I use different mushrooms?
Button, cremini, or even portobello all work great here.

Does the chicken need to be cooked before baking?
No, it cooks fully in the oven as long as it’s thinly sliced.

How do I keep it from being watery?
Don’t overdo the broth or use veggies with high water content without pre-sautéing.
