Instructions

1. 1

   Preheat the oven

   Heat the oven to 200°C.

2. 2

   Season the chicken

   Cut a pocket into each chicken breast. Drizzle with olive oil and balsamic glaze, then season all over and inside each pocket with salt, pepper, a dusting of cumin and coriander, and oregano. Set the breasts in a baking tray.

3. 3

   Soften spring onions

   Put the spring onions and 60 ml olive oil in a pan over medium-high heat. Cook for about 3 minutes, until softened.

4. 4

   Warm the garlic

   Add the grated garlic and cook for about 30 seconds.

5. 5

   Wilt the spinach

   Add the spinach and cook for about 8 minutes, until wilted and most of its liquid has evaporated.

6. 6

   Mix the filling

   Mash the feta with a fork in a large bowl. Mix in the cream cheese or ricotta, season with black pepper, then add the mint and spinach mixture. Combine, taste and adjust the seasoning if needed.

7. 7

   Fill the breasts

   Spoon about ½ cup of filling into each chicken breast.

8. 8

   Make tomato sauce

   To make homemade marinara, heat olive oil with the onion over medium heat and cook until soft and golden. Add the garlic and warm it through, then stir in the remaining tomato-sauce ingredients and simmer for 10 minutes. Taste and adjust the seasoning if needed.

9. 9

   Sear the chicken

   Put the chicken in an ovenproof pan, such as a cast-iron skillet, and cook over medium-high heat for 5 minutes. Turn the chicken over and take the pan off the heat.

10. 10

    Add tomato sauce

    For the tomato-sauce option, pour in as much marinara as you like, aiming for sauce to reach about one-third to halfway up the chicken.

11. 11

    Bake until cooked

    Bake in the preheated oven until the chicken reaches an internal temperature of 74°C. The time depends on the thickness of the chicken; thicker pieces take about 18 minutes.

12. 12

    Rest the chicken

    Take the pan out of the oven and leave the chicken to rest for 5 minutes before serving.

13. 13

    Bake without sauce

    For the lemon-caper option, bake the chicken without sauce. Once cooked, transfer it to a plate and cover it with foil.

14. 14

    Make lemon sauce

    Put the skillet used to bake the chicken over medium heat and add the butter. Once melted, add the garlic, then immediately add the lemon juice. Pour in the chicken broth and bring to the boil. Add the capers and simmer for 3–5 minutes, until the sauce has reduced a little. Pour it over the chicken to serve.

15. 15

    Plan ahead

    To prepare ahead, assemble and fill the chicken, then cover the tray with plastic wrap and refrigerate it. This can be done up to a day in advance.

16. 16

    Bring to room temperature

    Before cooking, let the chicken come to room temperature for about 1–2 hours.

17. 17

    Bake a larger batch

    For a large batch of 8–12 portions or more, you can skip pan-frying one side. Bake the chicken in one or two large pans until it reaches an internal temperature of 74°C.

18. 18

    Choose accompaniments

    Serve with toasted bread, pasta or roasted vegetables.

What is spanakopita-style stuffed chicken?

Spanakopita is a Greek savoury pie traditionally filled with spinach and feta. This version borrows those familiar flavours and tucks them into chicken breasts instead of pastry.

The spinach is cooked down before being combined with feta, a soft cheese and mint, so the filling is savoury and easy to spoon into the pockets. Choose tomato sauce for a sweeter, heartier finish, or lemon-caper sauce for a sharper one.

Nutrition and macros by portion

The nutrition label shows one serving as written: 610 calories, 56g protein, 15g carbs, 36g fat.

Chicken supplies most of the protein, while the spinach and any tomato sauce contribute carbohydrates and fibre. Feta, cream cheese or ricotta, olive oil and the optional butter add much of the fat; serve with roasted vegetables or a modest portion of bread or pasta to round out the plate.

Build the spinach filling

Spinach first: cook it with the softened spring onions and garlic until wilted and most of its liquid is gone. This helps keep the filling from becoming watery inside the chicken.

Cheese and herbs: mash the feta before stirring in cream cheese or ricotta, black pepper and mint. Taste the mixture before filling the chicken, since feta brings its own saltiness.

Cut and fill the chicken

Make the pocket: use a sharp knife to cut into the thick side of each breast, stopping before cutting through the other side. A pocket with a closed edge is easier to fill and helps hold the mixture in place.

Measure the filling: the method allows about ½ cup per breast. If a breast is smaller, use less rather than forcing the pocket open.

Choose your sauce

Tomato: use the jarred marinara listed, or make the homemade tomato sauce from the onion, garlic, puréed tomatoes and seasonings. Add enough to come about one-third to halfway up the chicken in the pan.

Lemon and caper: bake the chicken without sauce, then use the skillet and its pan drippings to make the butter, garlic, lemon and broth sauce. The capers add a salty, briny note, so add less if you prefer a gentler flavour.

Check for doneness

Chicken breasts vary in thickness, so the baking time can vary too. Use the stated internal temperature of 74°C as the doneness cue; the method notes that thicker pieces take about 18 minutes.

After baking, rest the chicken for 5 minutes before serving. For the lemon-caper version, transfer it to a plate and cover with foil while you finish the sauce.

Make it ahead

The chicken can be filled, covered and refrigerated up to a day ahead. Keep it covered in the refrigerator until you are ready to cook.

The recipe advises bringing it to room temperature for about 1–2 hours before cooking. For food safety, avoid leaving raw chicken at room temperature for an extended period; follow current local food-safety guidance.

What to serve alongside

Toasted bread or pasta works well with either sauce, especially for catching any sauce left on the plate. Roasted vegetables make a simple side if you would rather keep the meal centred on the stuffed chicken.

With tomato sauce, choose a plain accompaniment that lets the filling stand out. With lemon-caper sauce, bread or a simply prepared vegetable balances its brighter, tangy flavour.

Recipe notes & tips

• Chop the spinach before cooking so it is easier to mix evenly into the cheese.
• Cook the spinach until most of its liquid has evaporated to help keep the filling from becoming loose.
• Season the chicken both around the outside and inside each pocket.
• Choose the tomato or lemon-caper sauce before cooking so you can follow the appropriate finishing steps.
• Check the thickest part of the chicken with a food thermometer rather than relying only on the baking time.
• Rest the chicken for 5 minutes before serving to let it settle after baking.

Variations

• Choose ricotta: use it in place of the cream cheese for a softer, milder filling.
• Use jarred marinara: pour in your favourite jarred sauce instead of preparing the homemade tomato option.
• Go lemony: skip the tomato sauce and finish the baked chicken with the lemon-caper sauce.
• Adjust the capers: use less than 2 tablespoons for a subtler briny flavour.
• Serve with pasta: add pasta alongside the chicken to make the sauce go further.

Common mistakes to avoid

• Cutting through the breast: stop before the knife reaches the far side so the filling stays enclosed.
• Leaving excess spinach liquid: cook until most has evaporated to avoid a watery filling.
• Overfilling the pockets: use about ½ cup per breast, and less for smaller pieces.
• Guessing the cooking time: thickness affects timing, so check for an internal temperature of 74°C.
• Adding tomato sauce to the lemon version: bake that option without sauce, then make the lemon-caper sauce in the skillet.
• Skipping the rest: leave the chicken for 5 minutes after baking before serving.

How to store

Refrigerate cooked leftovers in a covered container and use within 3–4 days. Reheat until piping hot throughout; keep any sauce with the chicken when reheating to help prevent it drying out.
