How to Make This Chicken Spinach Mushroom Bake
🥄 Step-by-Step Instructions
Step 1: Preheat & Layer
- Preheat your oven to 375°F (190°C).
- Place chicken in a single layer in a greased 9x13 pan.
- Top with spinach, then evenly scatter mushrooms over top.
Step 2: Season
- Sprinkle with pepper and herb and garlic seasoning to taste.
Step 3: Make the Sauce
- In a mixing bowl, whisk softened green onion cream cheese with olive oil and chicken broth until smooth and pourable.
Step 4: Assemble & Bake
- Pour sauce over chicken and veggies, spreading evenly.
- Lay foil loosely over the top (don’t seal).
- Bake for 20 minutes.
Step 5: Uncover & Bake Again
- Remove foil and bake uncovered 20–25 more minutes, until veggies are tender and sauce thickens.
Step 6: Add Cheese & Finish
- Sprinkle mozzarella over the top.
- Return to oven for 10 minutes uncovered until cheese is golden and bubbly.
Step 7: Let Cool & Serve
- Let it rest for 10 minutes before slicing and serving — this helps the sauce set up beautifully.
What to Serve It With 🍽️
This dish stands beautifully on its own, but here are a few low-carb pairing ideas:
- Cauliflower rice – to soak up that luscious sauce!
- Zucchini noodles – a light, pasta-style option
- Steamed broccoli or green beans
- Crisp side salad with lemon vinaigrette
Tips for Success 🔥
- Soften the cream cheese before mixing — it blends much easier.
- Don’t over-bake the chicken! Thin cuts cook quickly.
- Add the cheese at the end, not the beginning, for the best texture and browning.
- If your sauce looks thin, let the dish rest longer after baking — it thickens as it cools.
How to Store & Reheat
- Fridge: Store in airtight containers for up to 3 days.
- Freezer: Wrap tightly and freeze for up to 2 months.
- Reheat: Microwave single portions or reheat in the oven at 350°F until warmed through.
