Gathering these ingredients is straightforward, and you likely have many of them in your pantry already. The beauty of this dish lies in its simplicity.
How to Make It
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- In a medium saucepan, combine the rinsed quinoa and vegetable broth (or water). Bring to a boil, then reduce heat, cover, and simmer for 15 minutes, or until the liquid is absorbed and the quinoa is fluffy. Set aside.
- While the quinoa is cooking, in another medium saucepan, combine the rinsed lentils and 4 cups of water. Bring to a boil, then reduce heat, cover, and simmer for 20-25 minutes, or until the lentils are tender but not mushy. Drain any excess water and set aside.
- In a large skillet or pot, heat the olive oil over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes.
- Add the minced garlic, dried thyme, dried oregano, and smoked paprika (if using). Cook for another minute until fragrant.
- Stir in the cooked quinoa and cooked lentils. Add the can of diced tomatoes (with their juices), the thawed and squeezed-dry spinach, and the nutritional yeast (if using). Season generously with salt and freshly ground black pepper.
- Transfer the mixture to the prepared baking dish, spreading it evenly.
- If using, sprinkle the grated Parmesan cheese over the top.
- Bake for 25-30 minutes, or until the top is lightly golden and the bake is heated through and slightly bubbly around the edges.
- Let the bake sit for 5-10 minutes before serving to allow it to set. Garnish with fresh parsley, if desired.
This straightforward process results in a wonderfully hearty and comforting bake.
Nutrition at a Glance
- High in Protein: Both quinoa and lentils are excellent sources of plant-based protein, essential for muscle repair and satiety. This dish provides a substantial protein boost to fuel your day.
- Rich in Fiber: The combination of quinoa, lentils, and spinach contributes a significant amount of dietary fiber. Fiber aids digestion, promotes gut health, and helps regulate blood sugar levels, keeping you feeling fuller for longer.
- Packed with Vitamins and Minerals: Spinach is a powerhouse of vitamins A, C, and K, as well as iron and folate. Quinoa offers magnesium, phosphorus, and manganese.

How to Serve It
- As a Main Course: This bake is hearty enough to stand on its own as a satisfying vegetarian main dish. A simple side salad with a light vinaigrette is a classic accompaniment.
- With a Side of Greens: Serve it alongside steamed broccoli, sautéed kale, or roasted Brussels sprouts for an extra dose of vegetables and a complete, balanced meal.
- As a Side Dish: It can also be a nutritious and flavorful side dish to grilled chicken, fish, or a hearty stew.

Common Mistakes
- Not Rinsing the Quinoa: Quinoa has a natural coating called saponin, which can give it a bitter taste if not rinsed thoroughly. A good rinse under cold water removes this.
- Overcooking the Lentils: Lentils should be tender but still retain some structure. If they become too mushy, the texture of the bake can be affected. Cooking them until just tender is key.
- Not Squeezing the Spinach Dry: Frozen spinach contains a lot of water. If you don’t squeeze out as much moisture as possible, this can make your bake watery.
- Under-seasoning: This dish relies on building flavor. Don’t be shy with salt, pepper, and herbs. Taste and adjust seasoning as you go. The broth or water you use for cooking the quinoa can also be replaced with vegetable broth for extra flavor.
- Skipping the Resting Time: Allowing the bake to rest for a few minutes after coming out of the oven helps it set, making it easier to serve and improving its overall texture.
Being aware of these common pitfalls can help ensure a successful and delicious outcome every time you make this bake.

Storage and Reheating
- Storage: Allow the bake to cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 3-4 days.
- Reheating in the Oven: The best method for reheating is in the oven. Place a portion in an oven-safe dish, cover it with foil, and bake at 350°F (175°C) for 15-20 minutes, or until heated through. You can remove the foil for the last few minutes if you want the top to crisp up slightly.
- Reheating in the Microwave: For a quicker option, reheat individual portions in the microwave. Place the bake in a microwave-safe dish, cover loosely with a damp paper towel, and microwave on medium power for 1-2 minutes, or until heated through.
- Freezing: This bake freezes well. Cool completely, portion into freezer-safe containers or wrap tightly with plastic wrap and then foil, and freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
Proper storage and reheating ensure you can enjoy this nutritious bake even days after its initial preparation.
Leftover Ideas
- Quinoa & Lentil Salad: Flake leftover bake into a bowl, add chopped fresh vegetables like cucumber, bell peppers, and cherry tomatoes, and toss with a lemon-tahini dressing or your favorite vinaigrette.
- Stuffed Peppers: Use the leftover bake as a filling for bell peppers. Halve peppers, scoop out seeds, stuff with the bake, and bake until the peppers are tender and the filling is heated through.
- Quick Wraps or Pitas: Warm up the leftover bake and stuff it into whole wheat wraps or pita bread with a smear of hummus or a dollop of Greek yogurt.
- Topping for Baked Potatoes: Serve a generous spoonful of warmed leftover bake over a fluffy baked potato for a hearty and flavorful meal.
- Egg Frittata or Quiche Filling: Chop the leftover bake and incorporate it into a frittata or quiche recipe, adding eggs, a splash of milk, and any other desired cheeses or vegetables.
Giving leftovers a new life transforms them into exciting new meals, minimizing waste and maximizing flavor.
