Preheat the oven to 400°F (200°C). Cut the top off the pumpkin and set it aside for the lid. Scoop out the seeds and stringy pulp.
Sear the beef cubes in a skillet, then transfer them to a plate.
In the same skillet, sauté the onion and grated carrot for 3–5 minutes. Stir in the tomato paste, curry powder, salt, and water. Return the beef to the skillet and mix well.
Transfer the stew to the hollowed pumpkin and cover it with the reserved pumpkin lid. Bake for 1½–2 hours, until the beef is fork-tender.
Serve with fresh dill or parsley.
