How to Make Smoky Sausage Casserole

1. Prepare the Mash

Boil potatoes in salted water for 15–18 minutes until tender. Drain and mash with butter, milk, roasted garlic and chives until smooth and creamy. Season to taste and keep warm.

2. Brown the Sausages

Heat olive oil in a large casserole pan. Add the sausages and cook until browned on all sides, around 5–6 minutes. Remove and set aside.

Deglaze the pan with red wine, scraping up the caramelised bits from the bottom of the pan.

3. Build the Sauce

Add onion and carrots to the pan and cook for 5–6 minutes until softened and lightly caramelised.

Stir in garlic, tomato purée and smoked paprika, allowing the spices to toast slightly and release their aroma.

Add fresh chopped tomatoes, chicken stock, Worcestershire sauce, soy sauce, thyme and oregano.

4. Simmer the Casserole

Return the sausages to the pan and simmer gently uncovered for around 25 minutes until the sauce thickens and becomes rich and glossy.

Finish with a knob of butter for a silky restaurant-style sauce.

Season with salt and black pepper.

Serving Suggestion

To plate like a restaurant dish, spoon a circle of garlic-chive mash onto a warm plate. Place two sausages on top and spoon the smoky tomato casserole sauce around them.

Garnish with fresh parsley and a drizzle of good olive oil.
