• 1/2 cup warm heavy cream or whole milk
• 2 large yellow onions, thinly sliced into half-moons
• 2 cloves garlic, finely minced
• 2 tbsp all-purpose flour
• 2 cups rich beef bone broth or high-quality beef stock

👩‍🍳 Step-by-Step Instructions

1. 1
   Step 1: Place peeled potato chunks in a large pot and cover with cold water by 1 inch. Add 1 tablespoon salt. Bring to a boil over high heat, then reduce to medium and simmer for 15 to 18 minutes until completely fork-tender.
2. 2
   Step 2: While potatoes cook, heat 1 tbsp olive oil and 1 tbsp butter in a large skillet over medium-low heat. Add sausages and cook gently for 12 to 15 minutes, turning often until deep golden brown on all sides and cooked through (internal temp 160°F). Transfer sausages to a warm plate and cover loosely with foil.
3. 3
   Step 3: In the same skillet containing the savory sausage drippings, add the remaining 1 tbsp butter and the sliced onions. Cook over medium-low heat for 12 to 15 minutes, stirring occasionally, until sweet, soft, and deeply caramelized.
4. 4
   Step 4: Add minced garlic, thyme, and rosemary to the onions; cook for 1 minute until fragrant. Sprinkle the flour over the onions and stir constantly for 2 minutes to cook out the raw flour taste.
5. 5
   Step 5: Slowly pour in the beef broth, whisking continuously to prevent lumps. Stir in the Worcestershire sauce and mustard. Bring to a simmer, scraping up any caramelized brown bits from the bottom of the pan. Simmer for 5 to 7 minutes until glossy and thickened. Season with salt and pepper to taste. Nestle sausages back into the warm gravy.
6. 6
   Step 6: Drain the cooked potatoes completely. Return the drained potatoes to the dry, hot pot over very low heat for 1 minute, shaking gently to allow all excess steam to evaporate (steam-drying).
7. 7
   Step 7: Mash the potatoes thoroughly using a potato ricer or masher. Stir in 4 tablespoons of softened butter and warm cream until velvety smooth and fluffy. Season with salt and pepper.
8. 8
   Step 8: Plate generous mounds of warm mashed potatoes into shallow serving bowls, make a well in the center, top with 2 sizzling sausages, and ladle spoonfuls of luscious onion gravy all over. Garnish with sweet peas and fresh chives.
