High-Protein Creamy Chicken Mushroom Spinach Bake
Creamy Chicken Mushroom Spinach Bake
A cozy skillet-to-oven dinner – juicy chicken, earthy mushrooms, and wilted spinach in a garlic cream sauce
This bake is weeknight comfort that still hits your protein target. Chicken thighs (or breasts) roast under a blanket of mushrooms, spinach, and a silky garlic-Parmesan cream. Everything goes in one dish – brown, stir, bake, done.
The sauce stays rich without flour, so the carb count stays low. Serve it as-is, over cauliflower rice, or with a simple green salad. Family-friendly and excellent leftover the next day.

Key element – the cream sauce
Softened cream cheese melted with a splash of broth and a little heavy cream gives you a thick, clingy sauce that won’t break in the oven. Season well with garlic, salt, pepper, and a pinch of paprika. Don’t boil hard after the cheese goes in – gentle heat keeps it silky.

Ingredients
Instructions
- Heat the oven and season the chicken. Heat oven to 400F (200C). Pat chicken dry and toss with salt, pepper, Italian seasoning, and smoked paprika.
- Brown the chicken. In a large oven-safe skillet or casserole, heat oil and butter over medium-high. Sear chicken 2 – 3 minutes per side until golden (it will finish in the oven). Transfer to a plate.
- Cook the vegetables. In the same pan, sauté onion and mushrooms 5 – 6 minutes until the mushrooms release liquid and start to brown. Add garlic 30 seconds. Stir in spinach until just wilted.
- Make the sauce. Lower heat. Stir in cream cheese, broth, and heavy cream until smooth. Mix in Parmesan. Taste and adjust salt. Nestle chicken back into the pan and spoon sauce over. Top with mozzarella.
- Bake. Bake 18 – 22 minutes until chicken is cooked through (165F / 74C) and the cheese is bubbling and golden. Rest 5 minutes. Garnish with parsley and serve hot.
Notes & Tips
- Dry the chicken well so it browns instead of steaming.
- Don’t crowd the mushrooms – they need space to brown.
- Softened cream cheese melts smoother; cube it first.
- If the sauce looks thin, simmer 1 – 2 minutes before baking.
- Let it rest 5 minutes so the sauce thickens on the plate.
Variations & serving ideas
- 6 oz (170g) cream cheese, softened
- 1/2 cup heavy cream
- 1/3 cup chicken broth
- 1/2 cup grated Parmesan
- 11/4 cups shredded mozzarella
- Optional: pinch red pepper flakes, extra parsley
- Lighter: Use chicken breast and light cream cheese (sauce will be a bit thinner).
- Dairy-light: Swap half the cream for extra broth + 2 Tbsp extra Parmesan.
- Extra veg: Fold in steamed broccoli florets or sliced zucchini.
- Spicy: Add 1/2 tsp chili flakes or a spoon of Calabrian chili.
- Sun-dried tomato: Stir in 1/3 cup chopped sun-dried tomatoes with the spinach for extra savoriness.
- Bacon mushroom: Crisp 4 slices of bacon first; use a spoon of the fat to sear the chicken and crumble bacon on top.
- Artichoke spinach: Add 1 cup chopped artichoke hearts with the spinach for a dip-inspired bake.
- Cauli-rice bowls: Serve over cauliflower rice or zucchini noodles to keep it low carb.

Frequently asked questions
Can I use chicken breast?
Yes. Cut into even chunks and don’t overbake – breast dries faster than thighs. Check at 16 – 18 minutes.
How do I keep the sauce from splitting?
Use softened cream cheese, keep heat medium-low when you add dairy, and don’t boil the sauce hard. The oven finish should be a gentle bubble, not a hard boil.
Is this keto-friendly?
Yes. About 6g net carbs per serving with high protein and fat. Skip any starchy sides if you want to stay in keto range.
Can I make it ahead?
Assemble through the sauce step, cool, cover, and refrigerate up to 24 hours. Bake 5 – 8 minutes longer from cold, until the chicken is 165F.
What if I don’t have an oven-safe skillet?
Brown everything on the stove, then transfer to a 9×13-inch baking dish before adding mozzarella and baking.
How do I reheat leftovers?
Cover and reheat at 325F for 12 – 15 minutes, or microwave in short bursts with a splash of broth so the sauce stays creamy.
