Red Lentil Casserole Ingredients
• Looking to create a delightful Red Lentil Casserole? Here’s what you’ll need!
For the Casserole
- Basmati Rice – Provides the essential structure; if you don’t have any, long-grain white rice works well too!
- Red Lentils – These little gems are packed with protein and are crucial for thickening the dish—always opt for red/orange lentils for the best results.
- Neutral Oil – Aids in toasting the spices; any light oil like canola will do the trick!
- Curry Powder – Infuses the casserole with warm, earthy flavors; feel free to adjust based on your taste preferences.
- Garam Masala – This aromatic spice blend enhances the overall flavor, making it optional but highly recommended.

- Ground Ginger – Offers a subtle hint of spice; can be increased for a bolder flavor.
- Ground Cinnamon – A unique addition that rounds out the spice mix; experiment with the amount to taste!
- Kosher Salt – Essential for enhancing overall flavors; using Diamond Crystal kosher salt can yield the best results.
- Vegetable Broth – This flavorful liquid cooks your ingredients; for a non-vegetarian twist, chicken broth is a great substitute.
- Coconut Milk – Imparts a rich creaminess; if allergies are a concern, more broth can be used as a dairy-free alternative.
- Sweet Potato – Adds sweetness and vital nutrients; dice into small, even cubes for perfect cooking!
- Orange Bell Pepper – Not only adds color but also a lovely sweetness; feel free to swap with veggies like zucchini or cauliflower.
For Garnish

Step‑by‑Step Instructions for Quick Vegetarian Red Lentil and Rice Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This initial step ensures that the heat is perfectly distributed, allowing your casserole to cook evenly. Preparing the oven ahead of time means you can seamlessly move through the next steps without any delays.
Step 2: Rinse the Grains
Rinse 1 cup of basmati rice until the water runs clear, which helps remove excess starch. Also, wash 1 cup of red lentils thoroughly, checking for any stones. This step is crucial for achieving a light, fluffy texture in your red lentil casserole while ensuring the lentils are clean and ready for cooking.
Step 3: Toast the Spices
In a medium-sized pot, heat 2 tablespoons of neutral oil over medium heat. Add 2 teaspoons of curry powder, 1 teaspoon of garam masala, and a pinch of cumin, coriander, ginger, and cinnamon. Toast these spices for about 30 seconds, stirring continuously until fragrant, which enhances their flavors and warms the aroma of your kitchen.
Step 4: Add the Broth and Coconut Milk
Next, pour in 3 cups of vegetable broth and 1 can of coconut milk into the pot with the toasted spices. Whisk the mixture together and bring it to a gentle simmer over medium heat. This combination will create a flavorful liquid base for your red lentil casserole, making sure everything cooks together beautifully.
Step 5: Combine the Casserole Ingredients
In a 9×13 inch baking dish, combine the rinsed basmati rice, lentils, 1 diced sweet potato, and 1 diced orange bell pepper. Stir well to ensure even distribution of the ingredients. This creates a colorful base for your casserole, combining the grains and veggies for a satisfying finish.
Step 6: Pour the Simmering Liquid
Carefully pour the simmering broth mixture over the rice and vegetable combination in the baking dish. Make sure everything is submerged by gently stirring. This step is essential for infusing the flavors into your red lentil casserole while evenly cooking the rice and lentils.
Step 7: Cover and Bake
Cover the baking dish tightly with aluminum foil to trap steam. Place it into the preheated oven and bake for 25-30 minutes. Check for doneness when lentils are soft and the rice has absorbed most of the liquid. The casserole should be bubbling slightly at the edges and fragrant.
Step 8: Add Cashews and Toast
Once the casserole is cooked, carefully remove it from the oven and uncover. If using, sprinkle a handful of raw unsalted cashews on top. Return the dish to the oven for an additional 5 minutes to toast the cashews and help evaporate any excess liquid, creating a delightful texture.
Step 9: Serve and Enjoy
After toasting, remove the casserole from the oven. Garnish with chopped cilantro and lime wedges for a pop of freshness. This quick vegetarian red lentil casserole is now ready to be served, offering a warm, comforting dish perfect for family dinners!

Red Lentil Casserole Recipe FAQs
Which lentils are best for this casserole?
Absolutely use red or orange lentils, as they cook quickly and tend to break down, thickening the casserole beautifully. Avoid using green or brown lentils, as they hold their shape and won’t give you that creamy texture you’re looking for.
How long can I store leftovers?
You can store any leftovers of the red lentil casserole in an airtight container in the fridge for up to 3-4 days. Just ensure that it’s cooled completely before sealing to keep it fresh!
Can I freeze the red lentil casserole?
Yes! To freeze, portion out the casserole into airtight containers or freezer bags, removing as much air as possible. It will keep well for up to 3 months. To defrost, simply place it in the fridge overnight; when you’re ready to heat it, warm it up in the oven or microwave, adding a little vegetable broth if it appears dry.
What if my casserole looks dry while baking?
If you notice the casserole starting to look dry, don’t worry! Just add a splash of vegetable broth, cover it tightly with foil, and let it continue to bake. This step will help retain moisture and ensure your casserole remains deliciously creamy.
Are there any allergy considerations for this recipe?
Definitely keep an eye on the ingredients you choose. Substituting coconut milk is a great option for those with dairy allergies—just increase the broth amount instead. Additionally, check labels on spices and cashews if you have nut allergies to ensure they are produced in a safe environment.

Very much! This casserole is incredibly versatile. Feel free to swap in any leftover veggies, such as spinach, green beans, or even carrots. Just remember to chop them into small pieces to ensure they cook evenly along with the rice and lentils!
