Prepare the Beef: Trim off any hard fat or silver skin from the chuck roast. Cut into 1 to 1½-inch cubes. Set aside.
Coat the Beef: In a large 1-gallon resealable bag, combine the flour, paprika, pepper, and 1 teaspoon kosher salt. Add the cubed beef, seal the bag, and shake until the beef is evenly coated.
Sear the Beef in Batches: Heat the oil in a large Dutch oven over medium-high heat. Once hot, add the butter. When the butter melts, add half of the floured beef cubes, shaking off any loose flour first. Sear each piece on all sides, turning every 3–5 minutes, until browned. Transfer browned beef to a plate and repeat with remaining beef.
Sauté the Aromatics: Once all the beef is seared and removed from the pot, reduce heat to medium. Add diced shallots and minced garlic. Cook for 3 minutes, stirring often, until fragrant and translucent.
Deglaze the Pot: Pour in the Cabernet Sauvignon and scrape up any browned bits from the bottom of the pot. Stir in the beef stock, Worcestershire sauce, Italian seasoning, and remaining 1 teaspoon kosher salt.
Simmer the Beef: Return the seared beef to the pot. Stir everything together, cover with a tight-fitting lid, and bring to a boil. Once boiling, reduce heat to low and simmer for 40 minutes, covered.
Add Vegetables: While the soup simmers, chop red potatoes and carrots into bite-size pieces. After 40 minutes, add them to the pot. Stir well to coat with broth. Cover and simmer for an additional 40 to 50 minutes, or until the vegetables are fork-tender and the beef is melt-in-your-mouth tender.
Taste and Adjust: Taste the broth and adjust salt if needed. Garnish with chopped parsley, if desired. Serve hot with crusty bread or a side salad.
