Prepare the Beef
Pat beef cubes dry with paper towels. Season generously with salt and pepper, then dredge lightly in flour.
Brown the Meat
Heat oil in a large Dutch oven over medium-high heat.
Brown beef in batches (4–5 minutes per batch), turning to sear all sides until deep golden brown.
Transfer to a plate.
Cue: A rich, meaty aroma and browned bits at the bottom of the pot are signs of flavor building.
Sauté the Vegetables
In the same pot, add onion, carrots, and celery. Cook for 4–5 minutes, stirring, until softened and lightly caramelized.
Stir in garlic and tomato paste; cook for 1 minute, until fragrant.
Deglaze with Guinness
Pour in the Guinness stout, scraping the bottom of the pot to loosen browned bits.
Simmer for 3–4 minutes to let the alcohol cook off slightly.
Simmer the Stew
Return beef to the pot. Add beef stock, Worcestershire sauce, thyme, and bay leaves.
Bring to a boil, then reduce to low heat. Cover and simmer gently for 1 ½ to 2 hours, until beef is fork-tender.
Add Potatoes & Carrots
Stir in potatoes and cook uncovered for 30–40 minutes, until vegetables are tender and broth has thickened.
Taste and adjust seasoning with salt and pepper.
Finish & Serve
Remove thyme sprigs and bay leaves.
Ladle into bowls, garnish with chopped parsley, and serve hot.
Cue: The stew should be glossy and rich, with melt-in-your-mouth beef and tender vegetables.
