# Cooking Steps:

01 - Preheat oven to 375°F.
02 - In a medium saucepan, combine lentils and vegetable broth. Bring to a boil, reduce heat, and simmer uncovered for 20 to 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 to 3 minutes until fragrant.
04 - Add carrots, zucchini, bell pepper, and mushrooms. Cook, stirring occasionally, for 5 to 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 to 3 minutes until spinach wilts.
06 - Transfer cooked lentils and sautéed vegetables to 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 to 25 minutes, until the top is golden and the casserole is bubbling.
09 - Let rest for 5 minutes before serving.

# Expert Ideas:

01 -
  • It actually tastes better the next day, so you can make it ahead without any guilt.
  • Every vegetable softens into the lentils, creating this understated richness that makes you feel like you've done something right in the kitchen.
02 -
  • Don't overcook the lentils at the beginning because they'll keep cooking in the oven, and nobody wants a casserole that's turned into lentil paste.
  • If your vegetables release a lot of liquid, drain the skillet before combining with the lentils, or you'll end up with something soupy instead of cohesive.
03 -
  • If you want extra texture, toast the breadcrumbs lightly in a dry skillet before sprinkling them on top so they stay crisp instead of absorbing moisture.
  • Add a squeeze of lemon juice to the finished casserole if it tastes a little flat, the acidity wakes everything up without tasting sour.
