Instructions

Preparation: Peel and cube the potatoes and rutabaga. Boil them separately in salted water until fork-tender, approximately 15-20 minutes for the potatoes and 20-25 minutes for the rutabaga.
Mash the Vegetables: Drain the boiled vegetables and mash them together with butter, salt, pepper, and heavy cream until smooth and creamy. Keep this warm while you prepare the filling.
Sauté Base Vegetables: Heat olive oil in a pan over medium heat, then add the chopped onions. Sauté until softened, about 3-4 minutes. Add the carrots and celery, cooking on low until tender, around 5-7 minutes.
Add Mushrooms and Aromatics: Incorporate the mushrooms into the pan and cook until tender and moisture has evaporated. Stir in minced garlic and fresh thyme until fragrant, about 1-2 minutes.
Create Sauce: Stir in tomato paste and Worcestershire sauce until combined. Gradually sprinkle in flour while stirring. Slowly add vegetable broth while stirring constantly, then bring the mixture to a boil. Let it thicken for about 5 minutes.
Combine Filling Ingredients: Stir in drained lentils and chopped parsley, mixing well to combine all flavors evenly.
Assemble the Pie: Transfer the filling into a baking dish. Generously top the filling with the prepared root vegetable mash, spreading evenly.
Bake: Bake the assembled pie in a preheated oven at 425°F (220°C) for 15-20 minutes, until the top is bubbly and golden brown.
Serve: Remove from oven and let cool for a few minutes. Garnish with extra parsley and serve warm for a comforting meal.

Notes

For a vegan option, use olive oil or dairy-free butter, substitute heavy cream with coconut or almond milk, and replace Worcestershire sauce with soy sauce or tamari.
Rutabaga can be substituted with turnips or parsnips according to preference.
Use dried thyme if fresh thyme is unavailable; reduce quantity to 1 teaspoon.
Make sure to mash the root vegetables until creamy for a smooth topping.
This dish freezes well; assemble and freeze before baking for a convenient make-ahead meal.
