Introduction

Gardener’s Pie with Root Vegetable Mash is a comforting, hearty dish perfect for chilly evenings. It combines a savory vegetable and lentil filling with a creamy, flavorful root vegetable mash topping. This vegetarian casserole is both nourishing and delicious.

A round red pan holds a baked dish with two main visible layers: the bottom layer is a rich brown sauce peeking out at the edges, and the top layer is a thick, creamy mashed potato topping that’s golden with lightly browned spots and sprinkled with small green parsley pieces. The pan is set on a white cloth on a dark wooden surface, with green pine branches and a lit candle in a wooden holder in the soft background, creating a warm, cozy feeling.

Ingredients

1 ½ lb (680 g) potatoes
¾ lb (340 g) rutabaga, or other root vegetable such as celeriac or turnip
4 tbsp (56 g) butter, softened
1 tsp (6 g) kosher salt, plus extra
2 – 4 tbsp (30 to 60 ml) heavy cream
2 tbsp (30 ml) olive oil
1 onion, diced
3 stalks celery, diced
2 carrots, diced
½ lb (227 g) mushrooms, sliced
3 garlic cloves, minced
1 tbsp (15 ml) chopped fresh thyme, or 1 tsp dried
1 tbsp (15 ml) tomato paste
1 tbsp (15 ml) Worcestershire sauce
1 tsp (6 g) kosher salt, plus extra
½ tsp (3 g) pepper
1 tbsp (8 g) all-purpose flour
1 cup (250 ml) vegetable broth
1 can (540 ml) canned lentils, drained
¼ cup (60 ml) chopped fresh parsley
Extra chopped fresh parsley, for garnish

Instructions

Step 1: Peel and cube both the potatoes and rutabaga. Divide into separate saucepans and cover with water. Season both with a generous pinch of kosher salt. Bring them to a boil and cook until fork tender. The rutabaga will take about 5 to 10 minutes longer than the potatoes. Drain and keep warm.
Step 2: Use a potato masher to roughly mash both the rutabaga and potatoes until almost smooth. Add the rutabaga to the potatoes along with the butter, kosher salt, and pepper and mash until smooth. Add 2 tablespoons of the heavy cream and mash together. If still too dry, add the remaining cream. Keep warm.
Step 3: Preheat the oven to 425°F. Place a wide skillet or shallow braiser over medium heat. Add the olive oil and onions. Season with a bit of kosher salt. Sauté for 2 to 3 minutes until the onions begin to soften.
Step 4: Add the carrots and celery. Turn the heat to low and sauté for 5 to 7 minutes, stirring regularly, until the vegetables soften.
Step 5: Add the mushrooms and cook for another 4 to 5 minutes until tender. When all vegetables are tender, add the minced garlic and fresh thyme. Sauté for another minute until fragrant.
Step 6: Stir in the tomato paste, Worcestershire sauce, kosher salt, and pepper. Cook briefly to combine.
Step 7: Stir the flour into the vegetables until fully incorporated. Slowly add the vegetable broth while stirring. Bring the mixture to a boil and cook until thickened.
Step 8: Add the lentils and cook for another 2 to 3 minutes to blend flavors. Stir in the parsley.
Step 9: Transfer the filling to a shallow casserole dish or leave in the braiser. Spoon the mashed root vegetable topping evenly over the filling.
Step 10: Bake for 15 to 20 minutes until the filling is bubbling and the top is lightly browned. Garnish with extra chopped parsley and serve warm.

Tips & Variations

Substitute rutabaga with celeriac or turnip to vary the flavor of the mash.
Add a sprinkle of grated cheese on top before baking for a richer crust.
Use dried herbs if fresh thyme or parsley is unavailable, but reduce quantities to avoid overpowering.
For a vegan version, replace butter with plant-based margarine and use a vegan Worcestershire sauce.

Storage

Store leftover pie in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through, about 15-20 minutes, to keep the topping fluffy. Avoid microwaving to prevent sogginess.

How to Serve

A round white pot with bright red handles holds a layered shepherd's pie. The top layer is uneven mashed potatoes with a golden brown crust and a sprinkling of chopped green herbs. The mashed potatoes cover almost the entire dish except one area, where a thick layer of cooked brown ground meat mixed with diced orange carrots, green celery, and small bits of onion is visible underneath. The pot sits on a white marbled textured surface with a soft gray cloth nearby. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I prepare Gardener’s Pie in advance?

Yes, you can assemble the pie a day ahead and keep it covered in the refrigerator. Bake it just before serving to ensure the topping stays fresh and the filling is hot.

What lentils work best for this recipe?

Canned brown or green lentils are ideal for this pie as they hold their shape well and have a hearty texture. Rinse and drain them before use to remove excess sodium.
