# What You'll Need:

→ Lentils

01 - 1 cup dried green lentils, rinsed
02 - 3 cups vegetable broth

→ Vegetables

03 - 1 medium onion, diced
04 - 2 cloves garlic, minced
05 - 2 medium carrots, sliced
06 - 1 medium zucchini, diced
07 - 1 red bell pepper, diced
08 - 1 cup button mushrooms, sliced

10 - 2 cups fresh spinach, roughly chopped

→ Herbs & Seasonings

11 - 2 tablespoons olive oil
12 - 1 teaspoon dried thyme
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 Make It:

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 20-25 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.

# Additional Tips::

01 -
  • It's secretly elegant: Looks like you fussed for hours, tastes restaurant-worthy, but comes together in about seventy minutes total.
  • Zero fussy techniques: This is throw-everything-together cooking that somehow delivers deep, satisfying flavors.
  • It gets better the next day: The spices settle and meld, making it perfect for meal prepping or unexpected guests.
02 -
  • Don't overcook the lentils in the first step: They'll soften further in the oven, and mushy lentils create a texture you won't love no matter how flavorful everything else is.
  • The resting period is not optional: Five minutes lets the casserole set up slightly so each serving stays together instead of collapsing into a beautiful but formless heap.
03 -
  • Mise en place is your friend: Chop and measure everything before you start cooking so the vegetable sauté moves smoothly and nothing burns while you're distracted.
  • Taste and adjust seasoning before it goes in the oven: The baking concentrates flavors, so if it seems slightly underseasoned in the bowl, it'll be perfect after baking.
