In a large stockpot, sear the Asado beef on all sides until browned.
Add onions, garlic, and celery. Sauté until softened and aromatic.
Toss in both fresh and dried mushrooms. These create that deep umami flavor we love.
Cover with water (or broth if you're feeling fancy), bring to a boil, then reduce to a gentle simmer.
Simmer uncovered for about 2 hours, occasionally skimming foam and adjusting seasoning.
Add the chopped root vegetables first (turnip, parsnip, pumpkin, carrots) and let them simmer for about an hour.
Stir in zucchini and tomato paste or salat adom.
Let everything simmer gently for another 3 hours, until the veggies are melt-in-your-mouth tender and the broth is full-bodied and rich.
Toss in fresh herbs during the last 15 minutes for a fresh, vibrant finish.
