Oven-Baked Tilapia with Spiced Yam Wedges (Nigerian Style)

How to Make It

1. 1

   Preheat & Prepare Your Trays

   Preheat your oven to 200°C (390°F) on the fan/convection setting. Line two large baking trays with parchment paper and lightly mist with cooking spray. Using two separate trays ensures the yam wedges and fish cook at their own pace without steaming each other.

   Tip: Convection/fan mode circulates hot air and gives you that desirable crisp exterior without a drop of deep-frying oil — critical for heart-health cooking.

   Season the Yam Wedges

   In a large mixing bowl, combine the yam wedges with 2 tablespoons of olive oil, smoked paprika (½ tsp), garlic powder (½ tsp), ground black pepper (¼ tsp), and turmeric (¼ tsp). Toss thoroughly until every wedge is evenly coated. Spread them in a single layer on one prepared baking tray — do not overlap.

   Tip: Yam has a naturally lower glycaemic index than Irish potato, making it a far superior choice for blood sugar management in Nigerian diabetic meal planning.

   Par-Bake the Yam Wedges

   Place the yam tray in the preheated oven and bake for 20 minutes, turning once at the 10-minute mark with a spatula. The wedges should be golden on the outside and beginning to soften through. They will finish cooking alongside the fish.

   Tip: Turning the wedges halfway ensures even browning on both sides — a simple trick that mimics the even crispness of deep-frying without the saturated fat load.

   Prepare the Tilapia Marinade

   While the yam bakes, combine in a small bowl: suya spice, remaining garlic powder, onion powder, ground crayfish, remaining turmeric, remaining smoked paprika, remaining black pepper, grated ginger, lemon juice, low-sodium bouillon powder, and 1 tablespoon of olive oil. Mix into a thick paste. Pat the tilapia fillets completely dry with paper towels, then rub the spice paste generously over both sides of each fillet.

   Tip: Patting the fish dry is non-negotiable — excess moisture creates steam in the oven and prevents the gorgeous crust from forming. Dryness equals crispness.

   Arrange the Fish Tray

   Place the marinated tilapia fillets on the second prepared baking tray, skin-side down. Arrange the sliced tomatoes and bell pepper rings around the fish — they will roast gently and create a light natural sauce at the base of the tray, adding lycopene and vitamin C without any extra calories.

   Tip: Roasting tomatoes alongside the fish releases lycopene in a more bioavailable form — excellent for cardiovascular and anti-inflammatory nutrition goals.

   Bake the Fish & Finish the Yam

   At the 20-minute mark, slide the fish tray into the oven on the upper rack and move the yam tray to the lower rack. Bake both together for a further 15 minutes until the fish is cooked through (flesh flakes easily with a fork and is opaque all the way through), and the yam wedges are golden and crispy at the edges.

   Tip: The internal temperature of fully cooked fish should reach 63°C (145°F). If you don't have a thermometer, the fillet should flake cleanly with gentle fork pressure at the thickest point.
7. 7

   Rest, Plate & Garnish

   Remove both trays from the oven and allow the fish to rest for 2 minutes — this allows juices to redistribute and prevents the fillet from falling apart on the plate. Plate each serving with one tilapia fillet, a generous portion of yam wedges, and the roasted tomatoes and peppers on the side. Finish with a scatter of freshly chopped parsley or scent leaf and an extra squeeze of fresh lemon juice.

   Tip: Scent leaf (efirin) is rich in antioxidants and adds authentic Yoruba flavour notes. Use it freely — it is a functional herb with real anti-inflammatory and antimicrobial properties recognised in Nigerian ethnomedicine.
