Ingredients:
- 450g Cremini mushrooms, roughly chopped
- 2 cans (15 oz each) brown or green lentils, drained and rinsed
- 1 large yellow onion, finely diced
- 3 cloves garlic, minced
- 150g frozen peas and carrots mix
- 2 tbsp tomato paste
- 1 tbsp balsamic vinegar
- 350ml rich vegetable stock
- 1 tbsp fresh thyme
- 1 tsp smoked paprika
- 1 tbsp all-purpose flour
- 1.1kg Yukon Gold potatoes, peeled and quartered
- 56g unsalted butter
- 120ml whole milk
- 50g grated white cheddar cheese
- 1.5 tsp sea salt
- 0.5 tsp cracked black pepper
Instructions:
- Place quartered potatoes in a large pot of salted water. Bring to a boil and cook for 15 minutes until tender.
- While potatoes boil, heat a 12-inch cast iron skillet over medium-high heat. Add mushrooms to the dry pan and sear until they release moisture and turn deep mahogany brown for 8 minutes.
- Add diced onion and garlic to the skillet with a splash of oil. Sauté until translucent. Stir in the tomato paste, smoked paprika, and thyme, cooking for 2 minutes to caramelize the paste.
- Sprinkle flour over the vegetables and stir. Deglaze the pan with balsamic vinegar, then slowly whisk in the vegetable stock. Add the lentils and frozen peas/carrots. Simmer for 5-7 minutes until thickened.
- Drain the cooked potatoes. Mash with butter, milk, salt, and pepper until rustic and chunky. Stir in half of the cheddar cheese.
- Spread the potato mash over the lentil filling in a baking dish. Use a fork to drag across the surface, creating deep ridges (the Fork-Crinkle technique). Sprinkle with remaining cheese.
- Place in a 200°C oven for 20 minutes until the ridges are golden-brown and crispy.
- Let the pie sit for 10 minutes until the filling sets slightly before serving.
