Tuna-Stuffed Sweet Potato: Easy Post-Training Recovery Meal

Why This Recipe Works for Athletes

The tuna-stuffed sweet potato is a staple post-training recovery meal: the sweet potato provides fast-absorbing complex carbohydrates to replenish glycogen, while tuna delivers 30+ grams of lean protein per serving to begin muscle repair. It’s inexpensive, simple to prepare, and works equally well after a hard run, swim, or long bike session.

Ingredients

  • 1 large sweet potato (approx 300g)
  • 1 x 160g tin of tuna in spring water, drained
  • 2 tbsp Greek yoghurt (or light mayo)
  • ½ red onion, finely diced
  • 2 tbsp sweetcorn (fresh, frozen or tinned)
  • 1 tsp Dijon mustard
  • Squeeze of lemon juice
  • Fresh chives or spring onion to garnish
  • Salt and black pepper

Instructions

  1. Scrub the sweet potato and pierce all over with a fork. Microwave on full power for 6–8 minutes, turning halfway, until tender throughout. Alternatively, bake at 200°C for 45–50 minutes for a crispier skin.
  2. While the potato cooks, mix the drained tuna with Greek yoghurt, mustard, lemon juice, red onion, and sweetcorn in a bowl. Season well with salt and black pepper.
  3. Once the sweet potato is cooked, cut it open lengthways and gently press the sides to open the cavity.
  4. Spoon the tuna mixture generously into and over the sweet potato.
  5. Garnish with chopped chives or spring onion and serve immediately.

Nutrition Notes

Approximately 440 calories per serving: 36g protein, 60g carbohydrates, 5g fat. Eat within 30–60 minutes of finishing training to maximise the glycogen replenishment window. The sweet potato’s beta-carotene content also supports immune function — important during heavy training blocks. For extra calories after a very long session, add half a ripe avocado sliced alongside.
