1. Combine 2 tablespoons flour and smoked paprika in a large bowl; add the beef chunks. Season, to taste, with salt and pepper. Toss well to coat evenly. Heat a Dutch oven over medium heat, and add the oil. Brown the meat, in batches, taking care not to crowd the pan, turning to sear all sides, about 6 to 8 minutes per batch. Transfer the beef with a slotted spoon to a plate.
3. Add the onion and garlic to the pot and cook, stirring occasionally until just soft, 5 to 7 minutes, adding a few tablespoons water if the pot gets too dark or begins to burn. Add the beer, scraping the browned bits from the bottom of the pan with a wooden spoon. Stir in the broth, molasses and thyme.
4. Return the beef and any accumulated juices to the pot. Cover and reduce the heat to medium-low. Simmer until the beef is tender when pierced with the tip of a sharp knife, about 2 to 2 1/2 hours. Add the potatoes, carrots, and parsnips; continue to simmer, uncovered, until the vegetables are tender but not mushy, about 40 minutes more.
5. Stir together the remaining 1 teaspoon flour and melted butter to make a paste. Stir the flour mixture into the stew and simmer until the broth is slightly thickened, 1 to 2 minutes. Remove from heat. Discard the thyme sprigs and season, to taste, with salt and pepper. If desired, sprinkle with parsley. Transfer stew to a serving bowl and serve.
