Introduction
This Red Lentil Casserole is a comforting, aromatic dish that combines tender basmati rice and red lentils with warming spices and creamy coconut milk. Perfect for a cozy dinner, it’s easy to prepare and packed with flavorful, wholesome ingredients.

Ingredients
- 1 cup basmati rice
- 1 cup red lentils
- 2 tablespoons neutral oil (canola oil, etc.)
- 1 1/2 tablespoons curry powder
- 1 teaspoon garam masala
- 1 teaspoon ground cumin
- 1/2 teaspoon ground coriander
- 1/2 teaspoon ground ginger
- 1/8 teaspoon ground cinnamon
- 1 teaspoon Diamond Crystal kosher salt
- 2 1/2 cups vegetable broth
- 1 (13.5 ounce) can coconut milk
- 1 medium sweet potato, diced small (1/4 to 1/2 inch cubes)
- 1 medium orange bell pepper, diced
- Chopped cilantro and lime wedges for serving
- 1/3 cup raw unsalted cashews (optional)
Instructions
- Step 1: Preheat your oven to 375°F (190°C).
- Step 2: In a fine mesh sieve, rinse the basmati rice thoroughly until the water runs clear. Rinse and sort the red lentils, removing any stones or broken pieces.
- Step 3: Heat the neutral oil in a medium pot over medium heat. Once hot, add the curry powder, garam masala, cumin, coriander, ginger, and cinnamon. Toast the spices, stirring often, for about 30 seconds to release their fragrance.
- Step 4: Add the salt, vegetable broth, and coconut milk to the pot. Whisk to combine and bring the mixture to a rapid simmer over medium-high heat.
- Step 5: In a 9×13-inch baking dish, combine the rinsed lentils and rice with the diced sweet potato and bell pepper.
- Step 6: Carefully pour the simmering spiced broth over the rice and lentils in the baking dish. Stir gently to mix everything together.
- Step 7: Cover the baking dish tightly with foil or an inverted sheet pan. Place it on the middle oven rack and bake at 375°F for 25 to 30 minutes. Check the rice and lentils for doneness; if the lentils aren’t fully tender and starting to dissolve by 25 minutes, cover again and bake for an additional 10 to 15 minutes.
- Step 8: Remove the cover and sprinkle cashews over the casserole if using. Return to the oven for about 5 minutes to toast the cashews and evaporate any excess liquid. If not using cashews and the liquid has fully evaporated, skip this step.
- Step 9: Remove from the oven and serve garnished with chopped cilantro and lime wedges.
Tips & Variations
- For extra creaminess, gently stir in a few spoonfuls of yogurt or coconut cream just before serving.
- Swap orange bell pepper for red or yellow bell pepper for a slightly different flavor and color.
- If you prefer a spicier casserole, add a pinch of cayenne pepper or chopped fresh chili when toasting the spices.
- Use raw almonds or pine nuts instead of cashews for a different nutty crunch.
Storage
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the oven, adding a splash of water or broth if needed to restore moisture. This dish can also be frozen for up to 1 month; thaw overnight in the refrigerator before reheating.

FAQs
Can I use a different type of rice or lentils?
You can substitute basmati rice with jasmine or long-grain rice, but cooking times may vary. Red lentils work best here because they cook quickly and break down into a creamy texture. Other lentils may require longer baking time and won’t dissolve as fully.
Is this dish suitable for vegans?
Yes, this casserole is entirely vegan, using vegetable broth and coconut milk. Just be sure to use a neutral oil that’s plant-based and skip any optional garnishes that aren’t vegan-friendly.

Garnishes

Instructions
- Preheat Oven: Preheat your oven to 375°F to prepare for baking the casserole evenly.
- Rinse Grains: Using a fine mesh sieve, rinse the basmati rice thoroughly until the water runs clear. Rinse and sort the red lentils, removing any debris or broken lentils.
- Toast Spices: Heat neutral oil in a medium pot over medium heat. Once hot, add the curry powder, garam masala, cumin, coriander, ginger, and cinnamon. Toast the spices while stirring frequently for 30 seconds to release their aroma.
- Add Liquids and Salt: Stir in the kosher salt, vegetable broth, and coconut milk. Whisk well to combine and bring the mixture to a rapid simmer over medium-high heat.
- Prepare Baking Dish: In a 9×13-inch baking dish, combine the rinsed lentils and rice with the diced sweet potato and orange bell pepper.
- Combine and Stir: Carefully pour the simmering spiced broth over the rice and lentils mixture in the baking dish. Stir to combine all ingredients evenly.
- Bake: Cover the dish tightly with foil or an upside-down sheet pan and place it on the middle oven rack. Bake at 375°F for 25-30 minutes, then check for doneness – the lentils should be almost dissolved. If not yet done, cover and continue baking for an additional 10-15 minutes.

- Serve: Remove the casserole from the oven, garnish with chopped cilantro and lime wedges, and serve warm.

- Rinsing the rice and lentils removes excess starch and impurities, ensuring a clean taste and texture.

- If cashews are not desired or unavailable, you can omit them without sacrificing much texture.
- This casserole can be served as a main course or side dish.
- Leftovers keep well refrigerated for up to 3 days and taste great reheated.
