Ingredients (Serves 4)
- 2 medium eggplants, cut into 1 inch cubes, about 1 1/2 lb (680 g)
- 2 medium zucchini, cut into half moons, about 14 oz (400 g)
- 2 tablespoons olive oil (30 ml), plus 1 teaspoon (5 ml) for the couscous
- 1 medium yellow onion, diced, about 5 oz (140 g)
- 4 garlic cloves, minced, about 12 g
- 1 can diced tomatoes, 28 oz (800 g)
- 2 cups cooked brown or green lentils (360 g), drained
- 4 packed cups baby spinach (120 g)
- 2 teaspoons dried oregano (2 g)
- 1 teaspoon fine sea salt (6 g), plus more to taste
- 1/2 teaspoon black pepper (1 g)
- 1 cup whole grain couscous (170 g)
- 1 1/4 cups boiling water or low sodium vegetable broth (300 ml)
- Optional: 2 tablespoons chopped parsley (8 g) for serving
Step-by-Step Instructions
1. Roast the Eggplant and Zucchini
Heat the oven to 425°F (220°C). Place the eggplant and zucchini on a large rimmed sheet pan. Add 2 tablespoons olive oil (30 ml), 1/2 teaspoon salt (3 g), and a few grinds of black pepper. Toss well so the vegetables look lightly glossy, not oily.
Roast for 25 to 30 minutes. Stir once halfway through. The eggplant should look browned on the edges and soft in the center, and the zucchini should smell sweet and roasted. If the pan looks crowded, use two pans so the vegetables roast instead of steam.
2. Build the Tomato Lentil Mixture
Lower the oven to 400°F (200°C). Add the diced onion, garlic, diced tomatoes, cooked lentils, spinach, oregano, remaining 1/2 teaspoon salt (3 g), and black pepper to a large baking dish. Stir until the spinach starts to tuck into the tomatoes.
Add the roasted eggplant and zucchini. Fold gently so the soft eggplant keeps some shape. The mixture should look saucy, colorful, and thick enough to spoon.
3. Bake Until Bubbling
Bake uncovered for 25 to 30 minutes. The edges should bubble slowly, the top should deepen in color, and your kitchen should smell like roasted garlic, oregano, and warm tomatoes. Let the bake rest for 5 minutes so the sauce settles.
4. Steam the Whole Grain Couscous
While the bake rests, place the whole grain couscous in a heat safe bowl. Stir in 1 teaspoon olive oil (5 ml) and a small pinch of salt. Pour over 1 1/4 cups boiling water or broth (300 ml), cover the bowl, and let it sit for 5 minutes.
Fluff the couscous with a fork. The grains should separate easily and feel tender, not wet. If it tastes flat, add a tiny pinch of salt.
5. Serve the Bake
Spoon the couscous into bowls or onto plates. Add the bubbling eggplant lentil bake on top, letting the tomato sauce soak into the grains. Finish with parsley if you like a fresh, green bite.
Expert Troubleshooting and FAQs
Can I use canned lentils?
Yes. Canned lentils work well and save time. Drain and rinse them first so the bake tastes clean and the sauce does not become too salty.
Do I need to peel the eggplant?
No. The peel softens during roasting and helps the pieces hold together. If your eggplant is very large or the skin feels tough, you can peel half of it for a softer texture.
Why did my bake turn watery?
The vegetables may have steamed instead of roasted. Spread them out on the sheet pan and roast until the edges brown. Also let the finished bake rest for 5 minutes so the lentils can absorb some of the tomato juices.
Can I make this ahead?
Yes. Bake the vegetable and lentil mixture up to 3 days ahead and store it in the fridge. Reheat it covered until hot, then serve with fresh couscous for the best texture.
What can I use instead of whole grain couscous?
Cooked brown rice, quinoa, bulgur, or farro all work. Choose quinoa or rice if you need a gluten free option, since couscous is made from wheat.
