Brown the Sausage:In a large stockpot, cook the ground sweet Italian sausage over medium heat until fully browned. Break it up into small crumbles as it cooks. Once browned, remove the sausage with a slotted spoon and set aside, leaving the rendered fat in the pot for extra flavor.
Sauté the Aromatics:Add the minced garlic, chopped onions, and celery to the pot. Cook over medium heat until the onions become translucent and the celery softens, about 5-7 minutes.
Add the Potatoes and Seasoning:Toss in the peeled and chopped potatoes, stirring to combine. Sprinkle in the Badia Complete seasoning, salt, black pepper, onion powder, and fenugreek leaves. Mix everything well to coat the vegetables in the spices.
Deglaze the Pot:Stir in the stone-ground mustard and soy sauce, scraping up any browned bits from the bottom of the pot to add depth of flavor.
Simmer the Stew:Pour in enough water to fully cover the ingredients, about 8 cups. Bring the mixture to a boil, then reduce the heat to low. Cover the pot with a lid and let the stew simmer for 30-40 minutes, or until the potatoes are fork-tender.
Add the Sausage Back:Return the cooked sausage to the pot, stirring to combine. Let the stew simmer for an additional 10 minutes to meld the flavors.
Taste and Adjust:Give the stew a taste and adjust the seasonings as needed. Add a pinch more salt or pepper if desired.
Serve and Enjoy:Ladle the hearty stew into bowls and serve it piping hot. Pair with a crusty loaf of bread for an extra cozy meal.
