While sweet potatoes cook, heat olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add onion, carrots, and celery and cook until softened, about 8-10 minutes. Add garlic and cook for 1 minute more.

Cook Lentils
Stir in the rinsed lentils, vegetable broth, tomato paste, thyme, rosemary, and Worcestershire sauce. Bring to a boil, then reduce heat, cover, and simmer for 30-35 minutes, or until lentils are tender and liquid has mostly been absorbed. Stir in frozen peas and season with salt and pepper.

Assemble and Bake
Preheat oven to 375°F (190°C). Spread the lentil filling evenly in the bottom of the skillet (if not oven-safe, transfer to a baking dish). Spoon the sweet potato mash over the lentil filling, spreading it to cover completely. Bake for 20-25 minutes, or until the topping is lightly golden and the filling is bubbling.
