Slice your chosen favorite sausage into rounds (thickness as you prefer) and dice the potatoes into small cubes. Cut two stalks of celery into small pieces – the smaller, the better. Also, chop the carrots into small pieces.
In a pot, heat vegetable oil or olive oil and fry the sliced sausage for about 8 minutes until it’s properly browned. After that, remove the sausage from the pot and set it aside. Pour in some broth or white wine (about 1/3 cup) to deglaze the pot. Deglazing means using a liquid to loosen and remove the browned bits from the bottom of the pan, which adds flavor to the dish. While stirring, wait a few minutes until most of the liquid evaporates.
When the liquid has almost completely evaporated, add a bit of butter. Once it melts, add the onion, celery, and carrot. Sauté the vegetables for about 8 to 10 minutes. Then, add the tomato paste and grated garlic, mix with the vegetables, and fry everything together for about half a minute. After that, add the wheat flour, mix with the vegetables, and fry everything for another half a minute.
Now pour the broth into the pot. As you pour the broth, stir gently to avoid flour lumps from forming. Add the potatoes, sausage, and drained canned beans to the pot. Add dried herbs and spices: Italian seasoning, smoked paprika powder, and salt and pepper to taste. Once the broth comes to a boil, reduce the heat and simmer the stew for about 30 minutes until the potatoes are soft and the stew has thickened. You can sprinkle with chopped parsley. It's best served with bread. That's it. Enjoy your meal.
