1 red onion, roughly sliced: Adds a touch of sweetness and depth of flavor.
3 small carrots, sliced into rounds: Provides sweetness and texture, complementing the savory sausages.
400ml beef stock + 1 extra stock pot or cube: The beef stock creates a rich, flavorful base for the casserole.

2 tbsp tomato purée: Adds a slight tanginess and richness to the sauce.
1 tbsp dried thyme: A fragrant herb that pairs beautifully with the sausages.
1 tbsp Worcestershire sauce: A dash of this adds a punch of umami and a hint of sweetness.

1 tbsp cornflour mixed with water: This will help thicken the sauce to the perfect consistency.

Step-by-Step Guide:

Brown the sausages:
Start by heating a pan over high heat and spraying it generously with cooking spray. Add your sausages and fry them for a few minutes, turning them occasionally to brown all sides. You don’t need to cook them through at this stage—just get a nice color on the outside.
Prepare the slow cooker:
In your slow cooker, combine the browned sausages, onions, carrots, and potatoes. These veggies will cook down beautifully, soaking up all the savory juices from the sausages and stock.

Add the flavor base:
To the slow cooker, add the thyme, tomato purée, Worcestershire sauce, and both the beef stock and the extra stock pot or cube. This combination creates a deeply flavorful and rich sauce that ties the whole casserole together. Season with a pinch of salt and plenty of black pepper.
Cook low and slow:
Now it’s time to let the slow cooker work its magic. Cook the casserole on high for 4 hours or low for 6 hours. The slow, gentle heat will tenderize the sausages and vegetables, allowing all the flavors to meld together.
Thicken the sauce:
About 30 minutes before serving, stir in the cornflour mixture. This step will help thicken the sauce, giving it a luscious, silky consistency. Let it cook for the remaining 30 minutes to achieve the perfect texture.

Serve and enjoy:
After the sauce has thickened, your Slow Cooker Sausage Casserole is ready to serve! Enjoy it as is, or pair it with some extra veggies or your favorite side. For an extra indulgent touch, serve it with plenty of crusty bread to soak up that rich, flavorful sauce—trust us, you’ll want every drop.
