Harissa Roasted Veg & Lentils with Lemon-Tahini

UUser

A punchy sheet-pan dinner built around caramelized harissa-roasted vegetables piled over tender lentils and finished with a creamy, bright lemon-tahini sauce. It’s hearty, vegan, and great for weeknights because the oven does most of the work. Expect sweet-savory heat, crisped edges on the veg, and a tangy, nutty drizzle that ties everything together. Ideal for meal prep: the veg and lentils hold well and reheat beautifully.

Ingredients

  • Harissa Roasted Vegetables
  • Lentils
  • Lemon-Tahini Sauce
  • To Finish (Optional)

Instructions

Roast the vegetables

1

Heat the oven to 450°F / 232°C. Set a rimmed sheet pan inside to preheat (this helps browning).

2

In a large bowl, toss the sweet potato and red onion with the olive oil, harissa, cumin, smoked paprika (if using), salt, and pepper. Spread on the hot pan in a single layer.

3

Roast for 15 minutes, until the bottoms are starting to brown and you can smell the spices toasting.

4

Add the broccoli/cauliflower and bell pepper to the pan, toss to coat, and return to the oven.

5

Roast 12–18 minutes more, until the vegetables have deep browned edges and the sweet potato is knife-tender. Taste a piece and adjust salt if needed.

Cook the lentils

1

If using dried lentils: add lentils to a pot with plenty of water (about 4 cups), plus bay leaf and smashed garlic if using. Bring to a boil, then reduce to a lively simmer.

2

Simmer 20–30 minutes until the lentils are tender but not mushy. Drain well and season with salt.

3

If using canned lentils: warm them in a small pot with a splash of water and a pinch of salt until hot.

Make the lemon-tahini

1

In a bowl, stir together tahini, lemon juice, and a pinch of salt. It may thicken/seize—this is normal.

2

Whisk in warm water 1 tbsp at a time until the sauce is pourable like heavy cream. Add grated garlic if using. Taste and adjust salt/lemon.

Assemble

1

Spoon lentils into bowls, pile the roasted vegetables on top, and drizzle generously with lemon-tahini.

2

Finish with herbs and seeds, and a splash of vinegar or pickled onion if you like extra brightness.

Tip: For a bigger, crispier batch, use two sheet pans so the vegetables roast (not steam).

Notes

Spice control: start with 2 tbsp harissa and add more at the end or serve extra on the side. Meal prep: store roasted veg and lentils together 4–5 days refrigerated; reheat until hot and edges sizzle, then add sauce. Sauce keeps 3–4 days; it will thicken—loosen with warm water and a pinch of salt. Optional boost: add 1 can chickpeas to the sheet pan for the last 15 minutes to crisp and add extra protein.
