Beetroot and Red Onion Bruschetta: A Pre-Race Carb Snack

Why This Recipe Works for Athletes

Beetroot is one of the most evidence-backed performance foods in sport, rich in inorganic nitrates that convert to nitric oxide in the body — widening blood vessels, improving oxygen delivery to muscles and potentially reducing the oxygen cost of exercise. Paired with caramelised red onion on toasted sourdough, this bruschetta provides a palatable carb base with a nitrate boost that makes it an excellent pre-race snack eaten 90 minutes to 2 hours before competing.

Ingredients

2 slices sourdough or rye bread
200g cooked beetroot (vacuum-packed, not pickled), diced small
1 small red onion, thinly sliced
1 tbsp olive oil
1 tsp balsamic vinegar
Small handful fresh flat-leaf parsley or mint, chopped
Salt and black pepper to taste
Optional: 50g soft goat’s cheese or feta, crumbled

Instructions

Heat olive oil in a small pan over medium heat. Add the sliced red onion and cook gently for 8–10 minutes until soft and just caramelising at the edges.
Add the diced beetroot to the pan, stir to combine, and cook for a further 2 minutes. Add balsamic vinegar, stir through, and remove from the heat.
Toast the bread slices until golden and firm enough to hold the topping.
Spoon the warm beetroot and red onion mixture generously onto each slice of toast.
Scatter over the fresh parsley or mint. Season with salt and pepper. If using, crumble the goat’s cheese or feta over the top and serve immediately.

Nutrition Notes

Per serving (one bruschetta, without cheese): approximately 280 kcal, 50g carbohydrates, 6g protein, 5g fat. The beetroot provides 200–300mg of inorganic nitrate per serving — research suggests consuming this amount 2–3 hours before exercise for the nitrate-to-nitric-oxide conversion to take full effect. Adding goat’s cheese brings protein to around 12g, making it more suitable as a light meal. For dairy-free athletes, omit the cheese and add extra parsley for freshness.
