Trim any excess fat from the beef chuck and cut into 1-inch cubes.
Heat the olive oil in a large heavy-bottomed pot or Dutch oven over medium-high heat.
Add the beef cubes, sea salt, and black pepper to the pot, searing until browned on all sides, then remove the beef and set aside.
In the same pot, add the diced yellow onion, sliced carrots, and diced red bell pepper, sautéing for 5-7 minutes until the vegetables begin to soften.
Stir in the minced garlic, sweet paprika, and smoked paprika, cooking for 1 minute until the spices are fragrant and toasted.
Return the beef to the pot and pour in the tomato puree and beef broth, stirring well to deglaze the bottom of the pan.
Add the dried marjoram and bring the liquid to a boil, then immediately reduce the heat to low.
Cover the pot with a tight-fitting lid and simmer gently for 45 to 60 minutes, or until the beef is fork-tender and the sauce has thickened into a rich consistency.
