Ingredients you’ll need
- Brown or green lentils: hold their shape and bake up perfectly (avoid red lentils here).
- Aromatics: yellow onion and garlic for a flavorful base.
- Vegetables: zucchini, bell pepper, carrots, and baby spinach (or kale).
- Crushed tomatoes: for a saucy, Italian-style backbone.
- Italian herbs: dried Italian seasoning plus basil/oregano if you want to boost the flavor.
- Broth: vegetable broth to simmer the lentils and sauce.
- Cheese (optional but delicious): mozzarella for melt + Parmesan for salty depth (use dairy-free if needed).
- Olive oil, salt, pepper, red pepper flakes: to round everything out.
How to make Vegetable and Lentil Bake with Italian Herbs
1) Cook the lentils. Rinse lentils, then simmer in vegetable broth until tender but not mushy. Drain if needed and set aside.
2) Sauté the vegetables. In a large skillet, cook onion and carrots in olive oil until starting to soften. Add bell pepper and zucchini, then garlic, and cook until fragrant.
3) Build the sauce. Stir in crushed tomatoes, Italian seasoning, salt, pepper, and a pinch of red pepper flakes. Simmer a few minutes to thicken slightly.
4) Combine. Fold the cooked lentils into the sauce. Stir in spinach just until wilted.
5) Bake. Transfer to a casserole dish, top with mozzarella and Parmesan (if using), then bake until hot and bubbly. Broil briefly for extra golden edges if you like.
Recommended baking dish + timing
- Dish: 9×13-inch baking dish (or a deep 2.5–3-quart casserole).
- Bake: 375°F for about 20–25 minutes, until bubbling.
- Optional broil: 1–3 minutes to brown the top—watch closely.
Easy swaps and add-ins
- More veggies: mushrooms, cauliflower florets, or chopped broccoli.
- More richness: stir in a spoonful of pesto or a splash of balsamic vinegar.
- Make it spicy: increase red pepper flakes or add Calabrian chili paste.
- Gluten-free: naturally gluten-free as written (double-check broth and seasonings).
- Vegan: skip the cheese or use plant-based mozzarella/Parmesan.

Storage and reheating
- Refrigerate: store airtight up to 4 days.
- Freeze: cool completely, then freeze in portions up to 3 months.
