Instructions

Step 1: Place sausages in a large skillet and add enough water to cover halfway. Bring to a simmer over medium heat and cook for 10 minutes, then remove sausages and set aside.
Step 2: Add olive oil to the skillet over medium heat. Sauté chopped onion until soft and translucent, about 5 minutes. Sprinkle flour over onions and stir to form a roux, cooking for 1 minute.
Step 3: Gradually whisk in beef stock and cream, bringing to a simmer. Cook for 5 minutes until gravy thickens. Season with salt and pepper, then set aside.
Step 4: Boil potato chunks in salted water for 15-20 minutes until tender. Drain well, return to pot, and add butter and milk. Mash until smooth and creamy. Season with salt and pepper.
Step 5: Slice sausages and serve over mashed potatoes with generous gravy ladled on top.
