How to Make Mushroom Shepherd’s Pie Recipe

Step 1: Preheat Your Oven

Start by setting your oven to 400°F (200°C). Warming up your oven early ensures the pie bakes evenly and the mashed potato topping crisps up just right.

Step 2: Sauté the Vegetables

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Toss in the diced onions, carrots, and celery, letting them soften for about 5 to 7 minutes. This foundational sauté awakens their natural sweetness and lays the groundwork for a rich filling.

Step 3: Add Garlic and Mushrooms

Stir in the minced garlic and chopped mushrooms, cooking them until the mushrooms release their moisture and turn tender—about 5 to 7 minutes. This step creates that signature meaty, umami base that makes this Mushroom Shepherd’s Pie Recipe a real crowd-pleaser.

Step 4: Season and Simmer

Pour in the vegetable broth and soy sauce. Sprinkle the thyme, rosemary, salt, and pepper evenly. Let the mixture cook down for another 5 minutes, allowing it to slightly thicken so every bite is rich and flavorful.

Step 5: Incorporate the Peas

Stir in the peas until they’re warmed through and well combined. These little green gems add a burst of sweetness and a lovely textural contrast against the tender mushroom filling.

Step 6: Assemble the Pie

Transfer the hearty mushroom and vegetable mixture into a baking dish, spreading it evenly to form the base layer of your pie. Then generously spoon the creamy mashed potatoes over the filling. Smooth it out gently with a spatula and, if you like, use a fork to create little peaks that will crisp delightfully while baking.

Step 7: Bake to Perfection

Pop your assembled pie into the preheated oven and bake for 30 to 35 minutes, or until the potato topping turns a gorgeous golden brown. This final step melds all the flavors and textures together into a soulful, satisfying dish.

Step 8: Let It Cool

Remove the Mushroom Shepherd’s Pie from the oven and give it 10 to 15 minutes to cool slightly. This resting period helps the layers set, making it easier to serve and enjoy every comforting bite.

Make Ahead and Storage

Storing Leftovers

Keep any remaining Mushroom Shepherd’s Pie covered tightly in the refrigerator. It will stay fresh for up to 3 days, making it perfect for quick lunches or dinners after a busy day.

Freezing

This recipe freezes wonderfully. Portion it into airtight containers and freeze for up to 2 months. Just be sure to thaw overnight in the fridge before reheating for the best texture.

Reheating

Reheat individual servings in the microwave or warm the entire dish in the oven at 350°F (175°C) until heated through and bubbly. To regain some crispness on the mashed potato topping, a quick broil at the end works like a charm.
