• 2 large (about 680 g total; 1.5 lb)boneless, skinless chicken breasts
• 225 g (8 oz)cremini or white mushrooms, sliced
• about 90 g (3 cups)fresh spinach
• 240 ml (1 cup)double cream
• 120 ml (1/2 cup)chicken stock
• about 100 g (1 cup)mozzarella cheese, shredded
• about 50 g (1/2 cup)Parmesan cheese, grated
• 3 clovesgarlic, minced
• 5 ml (1 tsp), divideddried thyme
• about 1 g (1/2 tsp), optionalred pepper flakes
• to tastesalt and black pepper
• 30 ml (2 tbsp)olive oil or butter

Instructions

1. 1

   Season the chicken

   Heat the oven to 190°C (375°F). Pat the chicken breasts dry with paper towels, then season both sides generously with salt, black pepper and half the dried thyme.

2. 2

   Sear the chicken

   Warm the olive oil in a large oven-safe frying pan over a medium-high heat. Sear the chicken for 3–4 minutes on each side, until deeply golden. Move it to a plate; it will not be cooked through yet.

3. 3

   Cook the mushrooms

   Add the sliced mushrooms to the same pan and cook for 5–6 minutes, stirring now and then, until they release their liquid and begin to brown. Stir in the minced garlic and cook for 30 seconds, until fragrant.

4. 4

   Wilt the spinach

   Pour in the chicken stock and scrape up the browned bits from the bottom of the pan. Add the spinach in handfuls and stir for 1–2 minutes, until fully wilted.

5. 5

   Make the sauce

   Turn the heat to low and pour in the double cream. Stir in the remaining thyme, the red pepper flakes if using, and half the Parmesan. Simmer for 2 minutes, until the sauce thickens slightly, then taste and adjust the salt and pepper.

6. 6

   Top the chicken

   Return the seared chicken breasts to the pan and nestle them into the sauce. Spoon some sauce over each breast, then scatter the mozzarella and remaining Parmesan evenly over the dish.

7. 7

   Bake until golden

   Put the pan in the preheated oven and bake for 20–25 minutes, until the chicken is cooked through to an internal temperature of 74°C (165°F) and the cheese is bubbly and golden brown.

8. 8

   Rest before serving

   Leave the bake to rest out of the oven for 5 minutes before serving. Add fresh parsley or thyme as a garnish if desired.

What is chicken spinach mushroom bake?

This American-style chicken bake brings together seared chicken, mushrooms and spinach in a creamy sauce, finished with melted cheese. It takes cues from familiar skillet-and-casserole cooking rather than relying on a complicated technique.

The sequence makes the dish work: browning the chicken and mushrooms develops flavour, while baking the chicken in the sauce helps bring the separate elements together.

Nutrition and macros by portion

The nutrition label shows one serving as written: 520 calories, 0g protein, 0g carbs, 0g fat.

The chicken provides most of the protein, while the cream, olive oil or butter and cheeses contribute much of the fat. Spinach and mushrooms add some carbohydrate, with more coming from any starchy side you serve. Balance the plate with extra vegetables or salad, and choose bread, rice or potatoes if you want a more filling meal.

Choosing the ingredients

Chicken breasts: Two large breasts are seared before baking. If they are particularly thick or uneven, take care to check the centre temperature rather than relying only on the suggested time.

Mushrooms and spinach: Cremini or white mushrooms both suit the sauce. Fresh spinach goes in by handfuls and quickly wilts down.

Cheese: Mozzarella gives the top its stretchy melt, while Parmesan adds a savoury edge to both the topping and sauce.

Build flavour in the pan

Searing: Pat the chicken dry so it can brown well, and leave it undisturbed for a few minutes on each side. It only needs colour at this point; the oven finishes cooking it.

Deglazing: The chicken and mushrooms leave browned bits on the pan. Scraping these into the stock carries their flavour into the sauce.

Get the sauce texture right

Mushrooms: Cook them until their released liquid has mostly evaporated and they start to brown. This keeps the sauce from being diluted by excess moisture.

Cream: Simmer gently for the stated 2 minutes, stirring in the cheese, until the sauce thickens slightly. Keep the heat low so the cream warms without boiling hard.

Check the chicken for doneness

The oven time is a guide, since breast size and thickness affect how quickly the chicken cooks. Check the thickest part with a thermometer; it should reach 74°C (165°F).

Once out of the oven, let the dish rest for 5 minutes as directed. The sauce will settle a little, making it easier to serve alongside the chicken.

Serve it with

The creamy sauce pairs well with a simple green salad or steamed vegetables for a lighter plate. For a more substantial meal, serve it with bread, potatoes or rice to catch the sauce.

If serving with a side that needs cooking, prepare it while the chicken bakes so it is ready when the resting time is over.

Recipe notes & tips

• Dry the chicken well before seasoning to help it brown in the pan.
• Use a pan that can safely go from the hob into the oven.
• Cook the mushrooms until their liquid has mostly evaporated before adding the garlic.
• Add the spinach a handful at a time so it is easier to stir into the pan.
• Check the thickest part of each breast for 74°C (165°F), especially if they are different sizes.
• Let the bake rest for 5 minutes before serving so the sauce can settle.

Variations

• Use chicken thighs: Boneless thighs can be used, but check that they are cooked through before serving.
• Add extra greens: Stir in more spinach in handfuls and allow it to wilt before adding the cream.
• Make it spicier: Increase the red pepper flakes to suit your preference.
• Swap the mushrooms: Use another sliced mushroom variety in the same quantity.
• Change the herbs: Use fresh thyme in place of the dried thyme, adjusting the amount to taste.

Common mistakes to avoid

• Crowding the pan: Sear the chicken in batches if the pieces do not fit with space around them.
• Skipping the browning: Let the chicken develop a golden crust before taking it out of the pan.
• Adding garlic too early: Add it after the mushrooms have cooked so it has less chance to burn.
• Boiling the cream hard: Keep the sauce at a gentle simmer over low heat.
• Guessing the doneness: Check the thickest part of the chicken reaches 74°C (165°F).
• Cutting straight in: Rest the bake for 5 minutes before serving.

How to store

Refrigerate leftovers in a covered container and eat within 3 days. Reheat gently in the oven or microwave until piping hot throughout; the cream sauce may thicken as it cools.
