03 - 1/4 cup unsalted butter or vegan butter

05 - 2 tablespoons olive oil
06 - 1 large onion, finely chopped
07 - 3 garlic cloves, minced
08 - 2 medium carrots, diced
09 - 2 celery stalks, diced
10 - 10 oz cremini or button mushrooms, chopped
11 - 2 tablespoons tomato paste
12 - 1 teaspoon dried thyme
13 - 1 teaspoon dried rosemary
14 - 1/2 teaspoon smoked paprika
15 - 2 cups cooked brown or green lentils
16 - 1 cup vegetable broth
17 - 1 cup frozen peas
18 - 2 tablespoons soy sauce or tamari
19 - Salt and pepper to taste

→ Garnish

20 - Chopped fresh parsley

# How to Make It:

01 - Preheat oven to 400°F.
02 - Place peeled and quartered potatoes in a large pot of salted water. Bring to a boil and simmer for 15 to 20 minutes until fork-tender. Drain well.
03 - Mash the drained potatoes with milk and butter until smooth. Season with salt and pepper. Set aside.
04 - While potatoes cook, heat olive oil in a large skillet over medium heat. Add onion and garlic; sauté for 2 to 3 minutes until softened.
05 - Add carrots and celery to the skillet. Cook for 5 minutes, stirring occasionally.
06 - Stir in mushrooms and cook until they release their moisture and begin to brown, approximately 6 to 8 minutes.
07 - Add tomato paste, thyme, rosemary, and smoked paprika to the skillet. Cook for 1 minute, stirring constantly.
08 - Stir in lentils, vegetable broth, peas, and soy sauce. Simmer for 10 to 12 minutes until the mixture thickens. Season with salt and pepper.
09 - Spread the filling evenly in a 9x13 inch baking dish. Spoon mashed potatoes on top and spread smoothly. Use a fork to create decorative ridges.
10 - Bake for 25 to 30 minutes until the top is golden and the filling is bubbling at the edges.
11 - Let cool slightly. Garnish with fresh parsley before serving if desired.

# Additional Tips::

01 -
  • It's legitimately filling and satisfying without making you feel heavy afterward.
  • The mushrooms and lentils create a depth of flavor that converts even the skeptics at your table.
  • You can prep the filling hours ahead and just top with potatoes before baking, making it perfect for entertaining.
  • One dish feeds six people, and it reheats beautifully for lazy weeknight dinners.
02 -
  • Don't skimp on draining your potatoes; excess water makes the topping soggy and ruins the texture you've worked for.
  • The ridges on top aren't just for looks; they create surface area that crisps up beautifully and adds texture to every bite.
  • Mushrooms release water as they cook, so give them time to brown rather than rushing; this concentrates their flavor.
03 -
  • Use a potato ricer if you have one instead of a masher for the silkiest, most luxurious topping.
  • Make the filling a day ahead and refrigerate it; reheating it briefly before topping actually brings out the flavors even more.
