Grandma's Traditional Potato and Sausage Soup
The Midday Warmth: The Big Pot on the Stove
Tuesday at 6 p.m., standard supermarket pork sausage hits a heavy six-quart pot. As the sausage fat renders, heat radiates from a battered cast-iron pot simmering quietly on the back of the stove, anchoring a smoky Dublin Coddle that relies entirely on the staggering quality of good pork and earthy root vegetables. Master the "sweat"—coaxing profound sweetness from onions and Yukon Gold potatoes under a simple parchment lid without a hint of browning—then let the broth bubble and eat it while it's scalding.
Before you start
Prep the potatoes ahead for a weeknight shortcut.
You can peel and cube the potatoes the night before, storing them submerged in cold water in the fridge to prevent browning. Drain them just before cooking, but do not rinse them—you want all that residual starch to go straight into the pot.
Ingredients
- thick-cut bacon6 slices
- mild pork sausages1 lb
- European-style unsalted butter3 tbsp
- yellow onions2 large
- Russet potatoes2 lb
- leek1 large
- low-sodium chicken stock4 cup
- whole milk1 cup
- bay leaf1 med
- fresh thyme3 sprigs
- sea salt1 tsp
- black pepper1 tsp
- fresh parsley1 tbsp
Method
- 01
Render the bacon fat and brown the sausages.
Place a large, heavy-bottomed Dutch oven over medium heat, add the chopped bacon, and cook until crispy. Remove the bacon to a paper towel, leaving the rendered fat in the pot, then deeply brown the whole sausages on all sides before removing them to a cutting board to slice into bite-sized coins.
- 02
Sweat the vegetables under a parchment lid.
Reduce the heat to medium-low, add the butter to the hot bacon fat, and toss in the onions, leeks, and potatoes. Season generously with salt and pepper, press a piece of parchment paper directly onto the surface of the vegetables, cover with the heavy pot lid, and let sweat for 10 to 12 minutes without browning.
- 03
Simmer the soup.
Discard the parchment paper, return the sliced sausages to the pot, drop in the bay leaf and thyme, and pour in the chicken stock. Bring to a gentle boil, immediately reduce the heat to a low simmer, cover, and cook for 20 to 25 minutes until the potatoes yield easily to a wooden spoon.
- 04
Mash the potatoes to build an authentic texture.
Remove the pot from the heat and fish out the bay leaf and thyme stems. Use a potato masher to crush about half the potatoes directly in the pot, creating a creamy, starchy suspension that still retains plenty of whole rustic chunks.
- 05
Finish with dairy and garnish.
Stir in the whole milk and let the residual heat warm it through, making sure the soup does not boil. Ladle into wide bowls and garnish generously with the reserved crispy bacon and a shower of fresh parsley.
Notes
The potato choice is absolutely non-negotiable.
Red or waxy potatoes will stubbornly hold their shape and leave you with a thin, watery broth. The starch of a Russet is the chemical engine that thickens the soup naturally, accurately replicating the floury potatoes grown in rocky Irish soil.
Do not skip the vegetable sweat.
Trapping the steam with parchment paper concentrates the natural sugars and flavors of the onions and potatoes without allowing them to caramelize. This creates the profoundly earthy, sweet base essential to real Irish soup-making.
Hold back on the heavy spices.
The magic of this dish relies entirely on the interplay of sweet sweated onions, starchy potatoes, and salty pork. High-quality sea salt and plenty of cracked black pepper are all you need to transport the bowl straight to a Dublin kitchen.
