Spinach and Feta Stuffed Chicken Breast with Lemon-Garlic Roasted Vegetables

A juicy, golden-seared chicken breast stuffed with creamy feta and spinach, served alongside caramelised Mediterranean-style roasted vegetables with bright lemon and garlic.

Ingredients

• 4 boneless, skinless chicken breasts (about 6–8 oz / 170–225g each)
• 4 packed cups fresh spinach (about 120g)
• 6 oz (170g) feta cheese, crumbled
• 2 tbsp olive oil, plus more for vegetables
• 3 garlic cloves, finely minced (pantry staple)
• 1 tsp dried oregano (pantry staple)
• 1/2 tsp smoked paprika (optional but excellent; pantry staple)
• 1 lemon (zest + 2 tbsp juice)
• 1 medium red onion, cut into wedges
• 2 bell peppers (any color), cut into 1-inch pieces
• 1 zucchini, sliced into thick half-moons
• 1 pint cherry tomatoes (about 300g)
• Salt and black pepper (pantry staples)
• Toothpicks (optional but helpful)

Method

• 1

  Step 1: Heat oven + prep tray

  Preheat oven to **425°F / 220°C**. Line a large sheet pan with parchment (or lightly oil it). This high heat helps the veg caramelise instead of steaming.

  Step 2: Roast vegetables (start them first)

  On the sheet pan, toss **red onion, bell peppers, zucchini, and cherry tomatoes** with **2 tbsp olive oil**, **1/2 tsp oregano**, **a good pinch of salt and pepper**, and **half the minced garlic**. Spread out into an even layer (give them space—crowding = soggy veg). Roast for **15 minutes**.

  Step 3: Make the spinach-feta filling

  While the veg starts roasting, heat **1 tbsp olive oil** in a skillet over **medium heat**. Add remaining **garlic** and cook until **fragrant, about 20–30 seconds**. Add spinach and toss until **just wilted**, **1–2 minutes**. Tip into a bowl and cool for 2 minutes, then mix in **feta**, **lemon zest**, a pinch of **pepper**, and **smoked paprika** (if using). Taste and add a tiny pinch of salt only if needed (feta is salty).

  Step 4: Butterfly and stuff the chicken

  Pat chicken dry. Using a sharp knife, cut a deep pocket into the thick side of each breast (like a book), being careful not to cut all the way through. Divide filling between breasts, packing it in firmly. Secure with toothpicks if needed.

  Step 5: Season and sear for color

  Season chicken all over with **salt, pepper**, and remaining **1/2 tsp oregano**. Heat a large skillet over **medium-high heat** with **1 tbsp olive oil**. Sear chicken **2–3 minutes per side**, until **deeply golden** (it won’t be cooked through yet). This step builds flavor and helps keep the filling inside.

  Step 6: Finish in the oven with the vegetables

  Pull the sheet pan out of the oven. Stir vegetables and drizzle over **2 tbsp lemon juice**. Nestle the seared chicken breasts among the vegetables (leave any toothpicks in). Roast for **12–15 minutes**, or until chicken reaches **165°F / 74°C** in the thickest part. (If you don’t have a thermometer, slice into the thickest breast: juices should run clear and meat should be opaque.)

  Step 7: Rest and serve

  Rest chicken **5 minutes** (this keeps it juicy). Remove toothpicks. Serve each breast with a generous scoop of roasted vegetables, spooning any lemony pan juices over the top.

Tips

• **Prevent filling leaks:** Don’t overstuff. Pack firmly and use 2–3 toothpicks if the pocket wants to open.
• **Even cooking:** If breasts are very thick, lightly pound the thick end to even them out before stuffing (between parchment, gentle taps).
• **Make-ahead:** Stuff the chicken up to **1 day ahead**; refrigerate covered. Sear and roast just before serving.
• **Vegetable swaps (same method):** Eggplant chunks, mushrooms, or small potatoes work well—just cut potatoes smaller and give them an extra 10 minutes head start.
• **What to serve it with:** Warm **pita**, **couscous**, or a simple **olive-oil dressed salad** makes this feel like a full Mediterranean dinner.
• **Storage:** Refrigerate leftovers up to **3 days**. Reheat at **350°F / 175°C** until hot (microwave can make chicken a bit tough).
