Instructions

Alright, let's get started by preheating your oven to a nice 450 degrees Fahrenheit . While the oven warms up, grab about 12 cups of your favorite chopped mixed vegetables, 1 cup of fresh mushrooms chopped up, and 1 cup of pearl onions,all these will bring such lovely texture and flavor to our pie.

Now, for the topping, place your small potatoes on a baking sheet lined with foil,that makes clean up so much easier,and pop them in the oven. Let them bake until they're tender all the way through, which usually takes around 45 minutes . You'll know they're ready when you can easily pierce them with a fork or skewer. Once they're done, take them out and let them cool just enough so you can handle them without burning your fingers. Then peel off their skins; if the peels don't come off easily, no worries,just give them another minute to cool.

Next, press those warm potatoes through a ricer, food mill, or even a fine colander right into a big bowl,this step makes the mash so silky smooth and perfect for spreading later. Add in your salted butter and give it a good stir until everything is wonderfully blended and creamy. Follow that up by stirring in some milk to get that perfect fluffy texture. Don't forget to taste and season with salt, adjusting until it's just right for you.

Moving on to the filling, start by soaking your dried porcini mushrooms in 3 cups of hot water. Set that aside to let them rehydrate and release their rich, earthy flavors. In the meantime, grab a medium saucepan and combine your brown lentils with 1 peeled garlic clove, 1 teaspoon of kosher salt, and 4 cups of water. Bring this mixture to a boil, then lower the heat to a gentle simmer. Stir it occasionally to keep the lentils from sticking or clumping. Let them cook until they're tender but still have a bit of bite,this usually takes between 15 to 20 minutes . Once done, drain the lentils and discard the garlic clove which has done its job seasoning the lentils beautifully.

Heat up 3 tablespoons of olive oil in a large, heavy pot over medium heat. When the oil is shimmering, add in your chopped onions. Cook these, stirring every so often, until they become soft and translucent; this will take about 12 minutes . The slow cooking really brings out their sweetness. Now, toss in your minced garlic and let it cook for just about a minute until fragrant,watch it closely so it doesn't burn.

Next, stir in the tomato puree. Keep stirring constantly to prevent it from sticking and to help it caramelize just right. This should take about 2 to 3 minutes and will add such a deep, rich flavor to your filling. Then, add your bay leaves along with the dry white wine, scraping the bottom of the pot to loosen any browned bits,you know, all those tasty bits stuck to the pan that give great flavor.

Drain your porcini mushrooms, but don't toss that soaking liquid just yet. Slowly pour that liquid into the pot, leaving any grit or sediment behind. Bring this mix up to a simmer and let it reduce by half,that should take around 10 minutes . This step concentrates the flavors beautifully.

Once that's done, pour in your vegetable stock and continue cooking, stirring every so often until the liquid reduces by half again, which will take about 45 minutes . This slow reduction thickens the filling and layers it with so much depth.

Now, strain the mixture through a fine sieve into a large saucepan, discarding any solids left behind. In a small bowl, mix together the cornstarch with 2 tablespoons of water until it dissolves completely, then whisk this into your simmering liquid. Let it cook until your sauce thickens nicely, about 5 minutes . For an umami boost, whisk in the miso paste and season with salt and pepper to taste. Set this luscious sauce aside for now.

Head back to your oven, still at 450 degrees Fahrenheit . In a large bowl, toss your chopped mixed vegetables and pearl onions with the remaining 2 tablespoons of olive oil, 5 whole garlic cloves (yes, whole!), and rosemary sprigs. Season everything well with salt and pepper. Spread this mixture evenly across two rimmed baking sheets. Roast in the oven, giving the vegetables a good stir halfway through, until they're tender and caramelized,this should be about 20 to 25 minutes . When they're done, fish out the garlic cloves and pop them into a small bowl. Mash them up with a fork until smooth, then stir that roasted garlic into your sauce,it adds a wonderfully mellow, sweet garlic flavor. Don't forget to discard the rosemary sprigs now.

Here's a handy tip: you can prepare the lentils, sauce, and roasted vegetables up to a day in advance. Just cover everything separately and keep them chilled until you're ready to assemble and bake.

When you're ready to bring it all together, spread your lentils in an even layer in a 3 quart baking dish. Place the baking dish on a foil lined rimmed baking sheet to catch any drips. Next, toss the roasted vegetables with the fresh mushrooms and some chopped fresh herbs like parsley, chives, and sage for a fragrant touch. Layer this veggie mixture on top of the lentils, then pour that thickened sauce all over the vegetables,every bite should be bursting with flavor. Finally, spoon the creamy potato mixture evenly over the top, smoothing it out gently.

Pop the whole thing into your oven and bake until the top turns a gorgeous golden brown and the filling is bubbly and inviting,this takes about 30 minutes . Once it's out of the oven, let it rest for about 15 minutes before serving. This little resting period helps everything set up nicely, making it easier to serve and even more delicious to eat.

There you have it! A warm, comforting vegetable shepherd's pie that's packed with layers of flavor and perfect for sharing with friends or family.
