Red Pepper Rouille and Prawns Toasts

This sophisticated high-protein starter combines the bold, Mediterranean flavours of a classic red pepper rouille with succulent pan-seared prawns. The rouille, enriched with saffron and a hint of cayenne pepper, provides a creamy yet smoky base that complements the sweetness of the shellfish perfectly. Using shop-bought roasted peppers makes this an efficient yet impressive dish for any dinner party or weekend lunch.

Served on crisp sourdough baguette slices, these toasts offer a satisfying crunch and a boost of lean protein. The addition of salty capers provides a sharp contrast to the rich mayonnaise-based topping, creating a balanced and vibrant snack. Whether you are looking for a nutritious appetiser or a light savoury bite, these toasts are a simple way to bring a touch of coastal French flair to your kitchen.

How to make Red Pepper Rouille and Prawns Toasts

Preheat oven to 218°C. Finely chop garlic cloves with cayenne pepper and saffron in mini processor. Add roasted red pepper and vinegar to processor; blend until almost smooth. Blend in mayonnaise. Season rouille to taste with salt and pepper.

Transfer 80ml rouille to medium bowl. Add prawns and toss to coat. Arrange sourdough baguette slices on baking sheet. Spread each slice with rouille. Bake until bottoms of toasts are crisp and rouille is darker in colour, about 10 minutes.

Heat large nonstick skillet over medium-high heat. Add prawns, spreading in single layer. Cook until just browned and opaque in centre, about 2 minutes per side. Arrange toasts on plate. Place 2 prawns on each toast; sprinkle toasts with capers.
