Instructions

  1. Preheat your oven to 400°F (200°C). Bring a large pot of salted water to a boil.
  2. Peel and dice the potatoes into 1-inch cubes. Add to the boiling water and cook until tender, about 15-20 minutes. Drain and return to the pot.
  3. While potatoes cook, prepare the filling. Dice the onion and carrot. Slice the mushrooms. Strip the thyme leaves from the stems.
  4. In a large oven-safe skillet or Dutch oven, heat olive oil over medium-high heat. Add mushrooms and cook until browned, about 5-7 minutes. Add onion, carrot and thyme; cook until vegetables soften, about 5 minutes.
  5. Stir in tomato paste and garlic powder; cook for 1 minute. Sprinkle flour over the mixture and stir to coat. Add mushroom stock concentrate and 1 cup of water. Bring to a simmer and cook until thickened, about 5 minutes. Season with salt and pepper to taste. Remove from heat.
  6. Mash the cooked potatoes with butter and sour cream until smooth. Stir in half of the white cheddar cheese. Season with salt and pepper.
  7. Spoon the mashed potatoes over the mushroom filling, spreading evenly. Sprinkle the remaining white cheddar on top.
  8. Place the skillet in the oven and bake until the filling is bubbly and the cheese is melted, about 10-12 minutes. For a golden crust, broil for 2-3 minutes until the top is lightly browned. Let rest for 5 minutes before serving.

Recipe Tips

For extra flavor, use a mix of mushrooms like cremini and shiitake.

If you don’t have an oven-safe skillet, transfer the filling to a baking dish before topping with potatoes.

Let the shepherd’s pie rest for 5 minutes after baking to set the layers.

FAQ

Can I make this shepherd's pie ahead of time?

Yes, you can assemble the pie completely (without baking) and refrigerate for up to 24 hours. When ready to bake, add about 10-15 minutes to the oven time.

Can I use a different cheese?

Absolutely! White cheddar adds a sharp, creamy flavor, but you can substitute with regular cheddar, Gruyère or a dairy-free cheese.

Is this recipe gluten-free?

The recipe uses all-purpose flour, but you can substitute with a gluten-free flour blend. Also check that your stock concentrate is gluten-free.
