This Spanish beef stews lean on bold, smoky flavors and long, slow cooking to transform a tough cut of beef into something rich and spoon-tender. My version takes inspiration from regional dishes like estofado de ternera, building a base with onions, garlic, and plenty of smoked paprika before layering in piquillo peppers, carrots, and mushrooms. Dry red wine and tomatoes provide acidity and depth, while thyme and bay leaves perfume the stew as it gently braises in the oven.
