Step‑by‑Step Instructions for Gardener’s Pie with Root Vegetable Mash
Step 1: Prepare the Vegetables
Start by peeling and cubing your potatoes and rutabaga. In a large pot, bring salted water to a boil, then add the vegetables. Cook them until fork-tender, about 15–20 minutes, then drain and keep them warm to retain their moisture and flavor.
Step 2: Mash the Roots
In a mixing bowl, combine the drained potatoes and rutabaga while they are still warm. Add in softened butter, kosher salt, freshly ground pepper, and heavy cream to taste. Mash everything together until it reaches a smooth and creamy consistency, then set aside to keep warm while you prepare the filling.
Step 3: Sauté Aromatics
Heat olive oil in a large skillet over medium heat. Once hot, add the diced onion, sautéing it for about 3–5 minutes until softened and translucent. Then incorporate the diced celery and carrots, cooking for an additional 5–7 minutes until they are tender and fragrant, stirring occasionally for even cooking.
Step 4: Add Mushrooms and Flavorings
Stir in the sliced mushrooms, cooking until they are tender and have released their moisture, which should take around 4–5 minutes. Next, add minced garlic and fresh thyme, stirring for about 1 minute until the mixture is aromatic. This step brings a depth of flavor to the Gardener’s Pie filling.
Step 5: Build the Filling
In the skillet, mix in the tomato paste and Worcestershire sauce, ensuring everything is fully combined. Sprinkle the all-purpose flour over the vegetable mixture, stirring continuously until it is fully incorporated. Slowly add vegetable broth while stirring, bringing the mixture to a gentle boil to thicken, about 3–5 minutes. Finally, fold in the canned lentils and chopped fresh parsley.
Step 6: Assemble and Bake
Transfer the hearty filling into a casserole dish, spreading it evenly across the bottom. Spoon the creamy root vegetable mash on top, smoothing it out with a spatula to cover completely. Bake in a preheated oven at 425°F for 15–20 minutes, or until the topping is golden and bubbling. Garnish with additional fresh parsley before serving for a beautiful finish.

Gardener’s Pie with Root Vegetable Mash Recipe FAQs
How do I choose ripe vegetables for this Gardener’s Pie?
When selecting vegetables like potatoes and rutabaga, look for ones that are firm with smooth skin and free of dark spots or blemishes. Freshness greatly enhances the dish’s flavor and texture. For potatoes, I recommend picking ones that are medium-sized to ensure they’re tender once cooked.
What is the best way to store leftovers?
Absolutely! Leftover Gardener’s Pie can be stored in an airtight container in the refrigerator for up to 3 days. To keep it fresh, it’s best to reheat only the portions you plan to eat. Reheat thoroughly in the oven or microwave before serving, and you might consider adding a splash of vegetable broth to maintain moisture.
Can I freeze Gardener’s Pie?
Yes, you can! To freeze, allow the Gardener’s Pie to cool completely after baking. Wrap individual portions or the whole pie tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 3 months. When you’re ready to enjoy, thaw it in the refrigerator overnight for best results.
What if my filling turns out too watery?
Very! To avoid a watery filling, make sure you cook your vegetables thoroughly and allow excess moisture to evaporate before incorporating the broth. If you find it needs thickening, you can mix a bit more all-purpose flour with water to form a slurry and stir it into the filling while it simmers. Keep it at a gentle boil until it reaches your desired thickness.
Are there any dietary concerns I should keep in mind?
Definitely! If you have allergies, double-check your ingredients; for instance, some Worcestershire sauces are not vegetarian due to anchovies, so opt for a brand that specifies vegetarian ingredients if that’s important for you. Additionally, if serving to pets, avoid the use of onions and garlic, as these can be harmful to dogs and cats.
Can I make this recipe ahead of time?
Sure can! You can prepare the filling a day in advance. Simply store it in the refrigerator and assemble the pie just before baking. This not only saves time but allows the flavors to deepen overnight, making your Gardener’s Pie even more delicious!
