🧑🍳 Step-by-Step with Tips
🔪 Step 1: Season the Chicken
- Use smoked paprika for rich colour and taste
- Optional: Add a dash of balsamic vinegar or lemon zest for extra flavour
Tip: Let the chicken marinate while chopping veg if you’ve got time!
🥔 Step 2: Layer the Tray
- Potatoes go on the bottom — they need the most heat
- Chicken sits on top for crispy skin (if using thighs) or to avoid drying out
- Scatter veg evenly around
🔥 Step 3: Bake to Perfection
- Midway through roasting, give everything a toss
- Add tomatoes only in the last 10 mins so they don’t burst too early
Tip: For crispier results, turn on the grill for the final 2–3 mins
