Hearty layers of caramelized onions, seasoned lentils, and creamy mashed potatoes baked until golden.

# What You Need:

→ Caramelized Onions

01 - 2 tablespoons olive oil
02 - 4 large yellow onions, thinly sliced
03 - 1 teaspoon sugar
04 - 1 tablespoon balsamic vinegar
05 - 1/2 teaspoon salt

→ Lentil Filling

06 - 2 tablespoons olive oil
07 - 2 carrots, diced
08 - 2 celery stalks, diced
09 - 3 cloves garlic, minced
10 - 1 1/2 cups cooked green lentils
11 - 1 tablespoon tomato paste
12 - 1 cup vegetable broth
13 - 1 tablespoon soy sauce
14 - 1 teaspoon dried thyme
15 - 1 teaspoon dried rosemary
16 - Salt and pepper, to taste

→ Mashed Potato Topping

17 - 2 1/2 pounds potatoes, peeled and cubed
18 - 3 tablespoons vegan butter
19 - 1/2 cup unsweetened plant-based milk
20 - Salt and pepper, to taste

# How to Make It:

01 - Place the peeled, cubed potatoes in a large pot of salted water. Bring to a boil and cook until very tender, about 18-20 minutes. Drain, then mash with vegan butter and plant-based milk. Season with salt and pepper. Set aside.
02 - Heat olive oil in a large skillet over medium heat. Add the sliced onions and sprinkle with sugar and salt. Cook, stirring frequently, until deep golden brown, about 25-30 minutes. Splash in balsamic vinegar and cook 2 more minutes. Set aside.
03 - Heat olive oil in another large skillet over medium heat. Sauté carrots and celery for 5-6 minutes until softened. Add garlic and cook 1 minute more. Stir in cooked lentils, tomato paste, vegetable broth, soy sauce, thyme, and rosemary. Simmer 10 minutes, until slightly thickened. Season with salt and pepper.
04 - Preheat oven to 400°F. Spoon the lentil mixture into the bottom of a baking dish. Layer caramelized onions over the top. Spread mashed potatoes evenly over everything and use a fork to create ridges.
05 - Bake for 25-30 minutes, until the top is lightly golden. Let cool slightly before serving.

# Expert Tips:

01 -
  • The caramelized onions create a depth of flavor that makes you forget there's no meat involved
  • Everything comes together in one baking dish, meaning less cleanup and more time to enjoy your evening
02 -
  • Caramelizing onions properly cannot be rushed—trying to crank up the heat will burn them before they develop that sweet depth
  • The potato topping needs to be completely cool before you spread it, or it will mix with the filling instead of sitting on top
03 -
  • Use a wide pan for caramelizing onions—more surface area means faster evaporation and better browning
  • Don't skip the fork ridges on the potatoes—they're what create those crispy, golden edges everyone fights over
