04 - 2 cloves garlic, minced
05 - 2 medium carrots, sliced

13 - 1 teaspoon dried oregano
14 - 1/2 teaspoon smoked paprika
15 - 1/2 teaspoon ground black pepper
16 - 1/2 teaspoon salt, or to taste

→ Topping

17 - 1/3 cup grated Parmesan cheese, or vegan alternative
18 - 1/2 cup gluten-free breadcrumbs, optional

# How to Prepare:

01 - Preheat oven to 375°F (190°C).
02 - In a medium saucepan, combine lentils and vegetable broth. Bring to a boil, reduce heat, and simmer uncovered for 20-25 minutes until lentils are tender but not mushy. Drain any excess liquid.
03 - While lentils cook, heat olive oil in a large skillet over medium heat. Sauté onion and garlic for 2-3 minutes until fragrant.
04 - Add carrots, zucchini, bell pepper, and mushrooms. Cook, stirring occasionally, for 5-7 minutes until vegetables begin to soften.
05 - Stir in cherry tomatoes, spinach, thyme, oregano, smoked paprika, salt, and black pepper. Cook for another 2-3 minutes until spinach wilts.
06 - Combine cooked lentils and sautéed vegetables in a large mixing bowl. Mix well to combine.
07 - Transfer the mixture to a greased 2-quart baking dish. Sprinkle with Parmesan cheese and breadcrumbs if using.
08 - Bake uncovered for 20-25 minutes, until the top is golden and the casserole is bubbling.
09 - Let rest for 5 minutes before serving.

# Expert Tips:

01 -
  • It's the kind of meal that feels nourishing without any pretense, loaded with protein from lentils so you actually feel satisfied.
  • The vegetables soften into this gentle medley while keeping their character, and the herbs somehow tie everything into something greater than the sum of its parts.
  • One dish, minimal fuss, and it feeds four people or gives you leftovers that taste even better the next day.
02 -
  • Don't skip the rinsing step with dried lentils—no one wants a gritty casserole, and rinsing removes the dust and debris that can make the final dish feel wrong on your tongue.
  • If you're using canned lentils instead of dried ones to save time, drain them well and add them at the vegetable stage so they don't turn to mush during the long simmer.
  • The smoked paprika is what separates this from being just another vegetable bake—it adds a depth that makes people lean in and ask what you did.
03 -
  • Make this casserole a day ahead and refrigerate it—the flavors actually deepen overnight, and you just reheat it covered in a 350°F oven for about 15 minutes before serving.
  • If your baking dish isn't quite deep enough and the mixture seems crowded, it's perfectly fine to transfer it to a larger shallow dish; the casserole will cook evenly and actually develop a better golden top.
