Step‑by‑Step Instructions for Hearty Red Lentil and Rice Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature is ideal for baking the Hearty Red Lentil and Rice Casserole, ensuring a deliciously even cook. While the oven heats, gather your ingredients to streamline your cooking process.
Step 2: Heat the Oil
In a large, oven-safe skillet, pour in a few tablespoons of olive oil. Heat it over medium heat until it shimmers, signaling it’s ready for the next step. This important base will help to sauté the onion and create flavorful layers for the casserole.
Step 3: Sauté the Onions
Add the chopped onion to the hot skillet and sauté for about 5 minutes, stirring regularly until they become translucent and tender. This step builds foundational sweetness and depth in your Hearty Red Lentil and Rice Casserole, enhancing its overall flavor profile.
Step 4: Add the Garlic
Once the onion is ready, toss in the minced garlic and continue cooking for about 1 minute, stirring constantly. When fragrant, the garlic infuses the skillet with an inviting aroma, signaling the next stage of your meal prep.
Step 5: Incorporate the Carrots
Next, stir in the diced carrot, and cook for an additional 3 to 4 minutes until they soften slightly. This vibrant vegetable brings a touch of sweetness and color to your casserole, making it even more appetizing!
Step 6: Add Spices
Sprinkle the ground cumin, coriander, turmeric, paprika, and salt into the skillet. Stir well to coat the onion, garlic, and carrot mixture in these warm spices, which will bring depth and complexity to your Hearty Red Lentil and Rice Casserole.
Step 7: Mix in Lentils and Rice
Now, pour in the rinsed red lentils and rice, stirring to combine thoroughly. This is the heart of your casserole, so ensure everything is evenly distributed in the skillet for a balanced cook and beautiful presentation.
Step 8: Add Vegetable Broth
Slowly pour in the vegetable broth, and bring the mixture to a gentle simmer over medium heat. Watch for bubbles forming on the surface, which indicates that the flavors are starting to meld together nicely in your Hearty Red Lentil and Rice Casserole.
Step 9: Incorporate Diced Tomatoes
Stir in the canned diced tomatoes, mixing them evenly throughout the dish. Their acidity will cut through the richness, balancing the flavors perfectly. Allow the mixture to simmer for another minute to combine before moving to the oven.
Step 10: Bake the Casserole
Cover the skillet with a lid or aluminum foil, and carefully transfer it to the preheated oven. Bake for 30 to 35 minutes, or until the lentils and rice are tender and most of the liquid is absorbed. The bubbling edges will signal that it’s ready to come out.
Step 11: Fluff and Garnish
After baking, remove the casserole from the oven and let it cool slightly. Use a fork to fluff the mixture, gently mixing in chopped fresh parsley for a pop of color and freshness.
Step 12: Final Touches
If desired, sprinkle grated Parmesan cheese and freshly ground black pepper over the top, allowing it to melt slightly from the heat of the casserole. Serve warm, and enjoy the cozy, comforting delights of your Hearty Red Lentil and Rice Casserole!
Make Ahead Options
