01 -
Preheat oven to 175°C (350°F).
02 -
Heat vegetable oil in a large Dutch oven over medium-high heat. Working in batches to avoid crowding, brown short ribs on all sides until deeply caramelized. Remove browned ribs and set aside.
03 -
Reduce heat to medium. Add diced carrots, celery, and onion to the pot. Sauté until vegetables are softened, about 10 minutes. Stir in minced garlic and cook for 2 minutes longer.
04 -
Add tomato paste and mix to evenly coat vegetables. Sprinkle in flour and stir until vegetables are coated. Continue cooking for several minutes.
05 -
Pour in red wine and bring to a simmer, scraping the bottom of the pot to incorporate browned bits. Add whole tomatoes with juice, breaking tomatoes apart with a wooden spoon. Stir in water.
06 -
Place browned short ribs back into the pot, ensuring they are submerged in liquid. Add fresh parsley sprigs. Add more water if needed.
07 -
Bring to a strong simmer over medium-high heat, then cover. Transfer the pot to the preheated oven. Braise for 2 to 3 hours, checking at the 2-hour mark, until beef is fork-tender and shreds easily.
08 -
Remove pot from oven. Set short ribs aside. Pass contents through a fine mesh strainer into a large saucepan, pressing on solids to extract all liquid. Discard solids.
09 -
Simmer strained sauce over medium-high heat for at least 30 minutes, occasionally skimming off surface fat, until thickened and rich.
10 -
While sauce reduces, shred short ribs using forks. Once sauce is thick, stir shredded beef back in and mix thoroughly.
11 -
Boil peeled and quartered potatoes in a large pot of salted water until tender. Drain and return potatoes to pot. Add unsalted butter and mash until smooth.
12 -
Add sour cream and grated parmesan cheese to potatoes. Stir until creamy and combined. Adjust seasoning with salt and pepper.
13 -
Spoon parmesan mashed potatoes into bowls. Top generously with short rib ragu. Garnish with chopped parsley if desired. Serve immediately.
