Step-by-Step Instructions
Step 1: Preheat and prep the vegetables
Heat the oven to 425°F (220°C). Line a rimmed baking sheet with parchment for easy cleanup. Cut the zucchini and eggplant into 3/4-inch cubes and the bell peppers into 1-inch pieces. Toss the vegetables with 2 tbsp olive oil, oregano, garlic powder, crushed red pepper (if using), 3/4 tsp kosher salt, and 1/4 tsp pepper. Spread in a single layer without crowding.
Step 2: Roast until caramelized
Roast the vegetables for 25–30 minutes, stirring once halfway, until the edges are browned and the centers are tender. If you’d like extra color, broil for 1–2 minutes at the end, watching closely.
Step 3: Cook the quinoa
While the vegetables roast, place the rinsed quinoa, broth or water, and 1/4 tsp salt in a medium saucepan. Bring to a boil over medium-high heat. Cover, reduce heat to low, and simmer for 15 minutes. Remove from heat and let stand, covered, for 5 minutes. Fluff with a fork.
Step 4: Make the lemon herb dressing
In a small jar or bowl, combine 3 tbsp olive oil, lemon juice, lemon zest, garlic, Dijon, honey, parsley, mint, 1/4 tsp salt, and 1/8 tsp pepper. Shake or whisk until emulsified. Taste and adjust seasoning if needed.
Step 5: Prep the halloumi
Pat the halloumi slices very dry with paper towels to encourage browning. If your halloumi tastes very salty, give it a quick rinse and dry well again. This cheese browns best when dry and the pan is hot.
Step 6: Sear the halloumi
Heat 1 tsp olive oil in a nonstick or cast-iron skillet over medium-high heat. Add halloumi in a single layer and sear 2–3 minutes per side, until a deep golden crust forms. Transfer to a plate. Work in batches if needed to avoid crowding.
Step 7: Toss, assemble, and serve
While the quinoa is still warm, toss it with half of the lemon herb dressing. Fold in the roasted vegetables. Portion into 4 bowls. Top each with seared halloumi and drizzle with the remaining dressing. Garnish with chopped herbs and serve with lemon wedges.
Pro Tips
- Cut vegetables to similar size so they roast evenly and brown at the same pace.
- Rinse quinoa thoroughly to remove bitterness from saponins.
- Dress the quinoa while warm—it absorbs flavor better than when cold.
- Sear halloumi just before serving; it’s best hot and crisp from the pan.
- For deeper char on the vegetables, spread them out on two pans rather than crowding one.
Variations
- Grain swap: Use farro, bulgur, or couscous instead of quinoa (cook according to package directions).
- Spice shift: Replace oregano with 1–2 tsp za’atar or add 1/2 tsp smoked paprika to the vegetables.
- Protein/cheese swap: Try crisped chickpeas or grilled tofu for a vegetarian alternative, or swap halloumi for crumbled feta (no searing needed).
Storage & Make-Ahead
Cooked quinoa and roasted vegetables keep in airtight containers in the refrigerator for up to 4 days. Dressing keeps 1 week. Halloumi is best freshly seared; if storing, re-crisp slices in a hot dry skillet for 1–2 minutes per side. For meal prep, pack quinoa and veggies together and keep halloumi and dressing separate; reheat quinoa/veg, then add hot halloumi and drizzle with dressing just before eating. Quinoa freezes well for up to 2 months; thaw overnight in the fridge.
