▢2 carrots peeled + diced
▢2 ribs celery diced
▢4 cloves garlic peeled + minced

Instructions
Mashed Potatoes
If you have an Instant Pot you may use this Instant Pot method to make your mashed potatoes.
If you don’t have an Instant Pot, add your quartered potatoes to a pot and fill with salted water, covering 1 inch above the potatoes. Bring to a boil, and then lower heat to maintain a low boil and cook until fork-tender. Approx. 15-20 minutes. Once cooked, drain and return the potatoes to the pot. Mash them using a potato masher, add the milk and mix well. Taste for salt, add more if necessary, and set aside.
Filling
Meanwhile, sort through your lentils, discarding any small rocks, and rinse them well in a colander. Then place the lentils with 4 cups of water and a teaspoon of salt (or use broth for added flavour) in a small saucepot. Bring to a boil, then reduce heat and simmer for 20-22 minutes. Don’t overcook your lentils as they’ll continue cooking in the oven. Drain and set aside.
Use a large, deep pan to sauté the onion, carrot, celery, and garlic until soft, approx. 7-10 minutes. Then add the mushrooms and cook until reduced, approx. 5 more minutes.
While the veggies are sauteéing, use a bowl or large measuring cup to whisk together the 2 cups of broth, flour, balsamic, red wine, thyme, and sage. Then pour it into the pan with the sautéed veggies. Cook, stirring often until your gravy is slightly thickened, approx. 5 minutes.
Assembly + Bake
Preheat the oven to 400 degrees F. Then transfer the cooked lentils and sautéed vegetables with the gravy to your casserole dish and mix well. Top with the mashed potatoes and use a fork to create a crisscross pattern, if desired. This will make the top layer crispier when baking. (See process shots above.)
Bake your pie for 20-25 minutes, until the top is golden brown. Then remove from the oven and let rest for a few minutes before serving.
Notes
Don’t overcook your lentils as they’ll continue cooking in the oven and you don’t want them to turn to mush.
Use broth over water to cook your lentils and your potatoes for added depth of flavour.
For the wine (if using), make sure to use a good quality wine that you enjoy. If you don’t like the flavour for drinking, it’s not good enough for cooking with, either.
Store leftovers in your refrigerator for 3-4 days.
You may freeze an entire pie before baking if made in advance. Thaw in the refrigerator overnight and bake covered in foil for 30-40 minutes, removing the paper for the last 5-10 minutes to brown the top.
