Red Lentil Casserole Ingredients
• Get ready for a flavorful journey!
For the Base
- Basmati Rice – Provides structure and texture; you can swap it with long-grain white rice, but avoid brown as it requires more liquid.
- Red Lentils – Quick-cooking and turn creamy when cooked; use red or orange lentils for best results.
- Neutral Oil (e.g., canola) – Adds moisture and helps toast spices; olive oil is a great alternative.
- Vegetable Broth – Moisture and flavor hero; chicken broth works for a non-vegetarian option.
For the Flavor
- Curry Powder – Delivers depth of flavor; adjust it according to your taste preferences.
- Garam Masala – Enhances the dish with a fragrant spice blend; if you’re out, just add a little more curry powder.

- Ground Ginger – Infuses warmth; fresh ginger gives a more vibrant flavor.
- Ground Cinnamon – Adds a hint of sweetness; can be omitted or replaced with nutmeg for variation.
For the Veggies
- Sweet Potato – A natural sweetener and filling; you can replace it with diced carrots or butternut squash.
- Orange Bell Pepper – Offering sweetness and vibrant color; other sweet peppers work too.
For Toppings
- Raw Unsalted Cashews (optional) – Crunchy topping that adds texture; feel free to omit or replace with pumpkin seeds for nut-free meals.
- Chopped Cilantro and Lime Wedges – Fresh garnishes that elevate the dish; if cilantro isn’t your thing, parsley is a fine replacement.
- Kosher Salt – Essential for enhancing flavors; adjust according to your dietary needs.

Step‑by‑Step Instructions for Vegetarian Red Lentil Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature is perfect for baking the Vegetarian Red Lentil Casserole while ensuring the dish cooks evenly. Meanwhile, grab your baking dish ready for the next steps, so your casserole is in the oven quickly after preparation.
Step 2: Rinse Rice and Lentils
Rinse 1 cup of basmati rice and 1 cup of red lentils under cold water until the water runs clear. This step is crucial as it removes excess starch and impurities, helping achieve the perfect texture in your casserole. Set them aside in a colander while you prepare the flavorful base.
Step 3: Toast the Spices
In a medium pot, heat 2 tablespoons of neutral oil over medium heat. Add 1 tablespoon of curry powder, along with 1 teaspoon each of garam masala, ground cumin, and ground coriander, stirring constantly for about 30 seconds until they become aromatic. This toasting brightens the flavors and sets the stage for the delicious Vegetarian Red Lentil Casserole.
Step 4: Prepare the Liquid Base
Whisk in 1 teaspoon of kosher salt, 3 cups of vegetable broth, and 1 cup of coconut milk into the pot, bringing the mixture to a gentle simmer. Allow the flavors to meld for about 5 minutes, stirring occasionally. This creamy base is key for the casserole’s richness, so make sure it’s well combined before pouring over your rice and lentils.
Step 5: Combine Ingredients in Baking Dish
In a 9×13-inch baking dish, combine the rinsed rice, lentils, 1 diced sweet potato, and 1 chopped orange bell pepper. Mix them evenly to ensure every bite delivers a balance of flavors. The colorful vegetables will not only add taste but also a lovely visual appeal to your Vegetarian Red Lentil Casserole.
Step 6: Add the Liquid and Cover
Pour the simmering liquid from the pot over the rice and lentil mixture, carefully stirring to combine all the ingredients. Cover the baking dish tightly with aluminum foil to trap steam, which helps cook the ingredients thoroughly. This step is essential for ensuring that all components cook evenly and come together beautifully during baking.
Step 7: Bake the Casserole
Place the covered dish into the preheated oven and bake for 25-30 minutes. After this time, peek under the foil to check for doneness. The rice and lentils should be tender, and if they still feel firm, cover them back up and return to the oven for an additional 10-15 minutes, monitoring closely.
Step 8: Add Toppings and Finish Baking
Once everything is cooked through, carefully remove the foil and sprinkle 1/2 cup of raw unsalted cashews on top if desired. Return the casserole to the oven uncovered for an extra 5 minutes. This final step allows the cashews to toast up nicely while any residual liquid evaporates, leaving you with a perfect balance between creaminess and texture.
Step 9: Serve and Garnish
Remove the casserole from the oven, letting it cool slightly before serving. Garnish generously with chopped cilantro and lime wedges for a fresh and zesty finish. This Vegetarian Red Lentil Casserole is now ready to delight your family with its warm spices and comforting flavors, perfect for your weeknight dinner!
