Sausages with Caramelized Red Onions and Radicchio

This sophisticated high-protein dish elevates the humble sausage dinner into something truly special. The combination of sweet, slow-cooked red onions and the slight bitterness of wilted radicchio creates a complex flavour profile that perfectly complements savoury sausages. Finished with a splash of balsamic vinegar for acidity, this colourful stir-fry of vegetables offers a vibrant and nutritious alternative to traditional mash or heavy grains.

Ideal for a quick weeknight supper or a fuss-free weekend lunch, this recipe uses chicken and apple sausages for a lighter, lean protein source. The dish is naturally gluten-free and packed with antioxidants from the red brassicas, making it a healthy choice for those seeking a satisfying yet balanced meal. Serve it exactly as it is for a low-carb option, or with a side of crusty sourdough to soak up the balsamic glaze.

Ingredients for Sausages with Caramelized Red Onions and Radicchio

How to make Sausages with Caramelized Red Onions and Radicchio

Melt butter with 1 teaspoon olive oil in heavy large skillet over medium heat. Add red onions and cook until soft and golden brown, stirring often, about 25 minutes. Add radicchio and sauté until wilted, about 2 minutes. Add balsamic vinegar and cook over medium-high heat until liquid is absorbed, about 1 minute. Season to taste with salt and pepper. Keep onion-radicchio mixture warm while preparing sausages.

Heat remaining 1 teaspoon olive oil in another heavy large skillet over medium-high heat. Add chicken-apple sausages and cook until sausages are well browned and heated through, turning frequently, about 5 minutes.

Serve onion-radicchio mixture alongside sausages.
