How to Make Vegetarian Lentil Casserole

Step 1: Preparing Lentils

Rinse the brown lentils under cold water until clear. Simmer them in vegetable broth until tender but not mushy, about 20 to 25 minutes. This will create the perfect base with great texture for your casserole.

Step 2: Sautéing Vegetables

Meanwhile, finely chop onions, carrots, and celery. Sauté them in a bit of olive oil over medium heat until soft and fragrant, around 5 to 7 minutes. Add minced garlic during the last minute to avoid burning and maximize its flavor.

Step 3: Combining Ingredients

Mix the cooked lentils with sautéed veggies, diced tomatoes (natural), vegetarian Worcestershire sauce, and spices. Stir everything together gently, allowing the flavors to meld beautifully before transferring into a baking dish.

Step 4: Adding the Topping

Sprinkle the top of your casserole with plant-based cheese and finish with a layer of bread crumbs (natural) for a delightful crispy crust when baked.

Step 5: Baking

Bake in a preheated oven at 375°F (190°C) for 25 to 30 minutes, until the top is golden and bubbling. Let it cool for a few minutes before serving to let the casserole settle.

Pro Tips for Making Vegetarian Lentil Casserole

• Drain lentils well: To prevent a watery casserole, drain lentils thoroughly after cooking.
• Layer flavors: Sautéing vegetables brings out more depth in the dish than adding raw.
• Don’t overbake: Keep an eye on baking time to avoid drying out the casserole.
• Use fresh herbs: Adding thyme or parsley at the end brightens the flavor.
• Let it rest: Allowing the casserole to cool slightly helps it firm up and slice neatly.
