Step‑by‑Step Instructions for Easy Vegetarian Red Lentil Casserole with Coconut Milk
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature will help create a perfectly baked Easy Vegetarian Red Lentil Casserole. As your oven warms up, gather the necessary equipment, like a 9×13-inch baking dish, to smoothly transition into the next steps of your cooking adventure.
Step 2: Rinse the Grains
In a colander, thoroughly rinse the basmati rice and red lentils under cold water until the liquid runs clear, about 2-3 minutes. This step helps wash away excess starch and impurities, promoting a better texture in your casserole. Once rinsed, set them aside while you prepare the spice mixture.
Step 3: Toast the Spices
In a medium pot, heat 2 tablespoons of neutral oil over medium heat. Once hot, quickly stir in your curry powder, garam masala, ground cumin, ground coriander, and ground ginger. Toast these aromatic spices for 30 seconds, or until fragrant, allowing their complex flavors to bloom while you prepare the broth ingredients next.
Step 4: Combine Liquid Ingredients
Pour in 3 cups of vegetable broth and a can of coconut milk into the pot with the toasted spices. Add kosher salt, whisk everything together to combine smoothly, and bring it to a gentle simmer. This aromatic broth will enhance the flavors of your Easy Vegetarian Red Lentil Casserole as it cooks, setting the stage for a hearty dish!
Step 5: Mix in Vegetables and Grains
In your prepared 9×13-inch dish, combine the rinsed basmati rice, red lentils, diced sweet potato, and chopped orange bell pepper. Stir well to evenly distribute the ingredients, creating a vibrant base for your casserole that showcases the nutritious vegetables and grains.
Step 6: Add the Broth Mixture
Carefully pour the hot broth mixture over the rice and vegetable blend in the baking dish. Gently stir the combination, ensuring each grain and lentil is covered in the flavorful liquid. Afterward, cover the dish tightly with foil or an upside-down baking sheet to trap the moisture inside for optimal cooking.
Step 7: Bake the Casserole
Place the covered baking dish in the preheated oven and bake for 23-25 minutes. As it cooks, the basmati rice and lentils will absorb the flavorful broth. You’ll know it’s ready when the rice is tender and fluffy, and the lentils are soft, transforming your dish into a nourishing Easy Vegetarian Red Lentil Casserole.
Step 8: Uncover and Finish Baking
After the initial baking time, carefully remove the cover and bake for an additional 10-15 minutes. This step allows any excess liquid to evaporate, resulting in a perfectly moist casserole—watch for the bubbling edges as a visual cue that it’s perfectly baked.
Step 9: Serve and Garnish
Once done, take the casserole out of the oven and give it a gentle stir to mix everything together. For a finishing touch, garnish with freshly chopped cilantro and serve with lime wedges for added brightness. Your delicious Easy Vegetarian Red Lentil Casserole with Coconut Milk is now ready to be enjoyed!

Red Lentil Casserole Recipe FAQs
What type of rice is best for this casserole?

How should I store leftovers of this casserole?
Leftovers can be stored in an airtight container in the fridge for up to 3-4 days. It’s a fantastic option for meal prep! Just reheat it in the microwave or oven—if you’re using the oven, I suggest adding a splash of water to keep it moist.

What should I do if my lentils aren’t cooking properly?
Very good question! If you find that the lentils are still hard after the initial baking time, simply recover the casserole with foil and return it to the oven. Bake it longer, checking every 5-10 minutes. You may need to add a bit more broth to keep it moist, as some oven temperatures can vary.
Are there any dietary considerations I should keep in mind?
Yes, it’s vital to be aware of any allergies, especially with ingredients like coconut milk and the spices included.
