1 tablespoon corn starch – Helps stabilize and slightly thicken the mixture.
1 can (14 ounces) chopped tomatoes – Adds acidity and body to the sauce.
1 vegetable stock cube – Infuses depth and savory flavor.
1⅔ cups water (plus extra if needed) – Hydrates lentils and forms the cooking liquid.

1 teaspoon mixed dried herbs – Adds classic savory flavor.
1 teaspoon dried rosemary – Provides piney, aromatic warmth.
1 teaspoon dried oregano – Enhances Mediterranean depth.
Salt and black pepper, to taste – Balances and sharpens flavor.

For the Potato Topping

2–3 large russet potatoes, peeled and sliced ⅛-inch thick – Form the golden, crispy crust.
Olive oil, for drizzling – Promotes browning and crispness.
Additional black pepper and thyme – Enhance aroma and finish.

Step-by-Step Instructions

Preheat the Oven

Preheat your oven to 350°F (180°C) to ensure even baking and a properly crisp potato topping.

Sauté the Vegetables

Heat olive oil in a skillet over medium heat. Add onion and carrots and cook for 4–5 minutes until softened and slightly translucent.

Incorporate Garlic and Cornstarch

Stir in minced garlic and cook for 1–2 minutes until fragrant. Sprinkle in corn starch and stir to coat the vegetables evenly.

Build the Lentil Sauce

Add dried herbs, rosemary, oregano, tomato paste, tamari, red lentils, chopped tomatoes, and half the water mixed with the stock cube. Stir well, bring to a boil, then reduce to a gentle simmer for 15 minutes, adding remaining water as needed until lentils are tender and the mixture thickens.

Prepare the Potatoes

Peel and slice potatoes into uniform ⅛-inch discs. Thin slices ensure even cooking and crisp edges.

Assemble the Hotpot

Transfer the lentil mixture to a baking dish and level the surface. Arrange potato slices in slightly overlapping rows to fully cover the top.

Season and Cover

Drizzle potatoes lightly with olive oil and sprinkle with black pepper and thyme. Cover tightly with foil to trap steam.

Bake Covered

Bake for 30 minutes to soften the potatoes and allow flavors to meld.

Bake Uncovered Until Golden

Remove foil and bake for an additional 20 minutes, or until potatoes are golden brown and crisp at the edges.

Rest and Serve

Allow to cool for 5–10 minutes before serving to help the layers set.

Recipe Notes & Tips

Slice Potatoes Evenly – Uniform thickness ensures consistent cooking and crisp texture.
Simmer Lentils Thoroughly – Red lentils should be tender before baking to avoid undercooking.
Don’t Skip the Foil Step – Covered baking helps potatoes soften before browning.
Season Generously – Lentils absorb salt; taste and adjust before baking.
Use a Mandoline (Optional) – Ensures evenly thin potato slices.
Let It Rest Before Serving – Helps structure hold when portioning.

Troubleshooting Common Issues

Why This Recipe Works

This hotpot works because red lentils naturally break down and thicken the sauce as they cook, eliminating the need for heavy binders. The tomato base provides acidity, balancing the earthiness of lentils and herbs. Baking the dish covered first allows the potatoes to steam and soften, while finishing uncovered promotes caramelization through the Maillard reaction. The result is a layered texture: tender, savory lentils beneath crisp golden potatoes. At roughly 350–400 calories per serving, it’s a nutrient-dense, fiber-rich meal that remains satisfying without heaviness.

With a rich lentil base and crisp potato topping, this dish offers warmth, nourishment, and versatility in every bite. For a lighter option, reduce the oil slightly or add extra vegetables to increase volume without extra calories. Whether served as a cozy weeknight dinner or a rustic gathering dish, this hotpot delivers hearty goodness—entirely plant-based.
