Heat 1 tablespoon of olive oil in a large pot over medium-high heat. Place the chicken thighs in the pot, skin side down, and cook until golden, about 5 minutes. Flip them over and cook the other side until golden. If they stick to the bottom of the pot, they’re not ready to turn yet. Cook for 1-2 minutes longer, then try again.
Pour 1.5 liters (6 and ⅓ cups) of water over the chicken and bring it to a boil. Reduce the heat, cover, and simmer until the chicken is very tender, about 45 minutes. Remove the pot from heat.
Transfer the chicken thighs from the pot and pour the stock into a separate bowl.
Shred the cooked chicken with a knife and fork, discarding the skin and bones. Set the shredded chicken aside.
Heat the remaining 1 tablespoon of olive oil in the same pot. Add the tomato paste, dried mint, and paprika. Cook until fragrant, about 1 minute, stirring occasionally. Before it dries out, add the pureed tomato and cook for 1-2 minutes, stirring constantly. Then add the mashed garlic and cook for another minute.
Add the orzo, salt, and pepper. Stir well and cook for 2-3 minutes.
Pour the chicken stock back into the pot and bring it to a boil, stirring occasionally to prevent the orzo from sticking.
Once it boils, reduce the heat and simmer until the orzo is tender.
Add the shredded chicken, lemon juice, and chopped parsley. Stir and let everything simmer for a few more minutes.
Taste and adjust salt or lemon juice if needed, then serve warm.
