2 cups Brussels sprouts, halved – Add nutty flavor and crisp edges when roasted.
1 red bell pepper, diced – Contributes sweetness and vibrant color.
1 zucchini, sliced – Adds moisture and balances denser vegetables.

Fresh parsley, chopped – Adds freshness and visual contrast at the finish.

Step-by-Step Instructions

Preheat and Prepare

Preheat the oven to 425°F (220°C) and line a large baking sheet with parchment paper to prevent sticking and encourage even browning.

Chop the Vegetables

Place cauliflower, Brussels sprouts, bell pepper, zucchini, and red onion into a large mixing bowl, keeping pieces relatively uniform for even cooking.

Season Thoroughly

Drizzle olive oil over the vegetables, add the harissa paste, and season with salt and pepper. Toss well until all vegetables are evenly coated.

Arrange for Roasting

Spread the vegetables in a single layer on the baking sheet, leaving space between pieces to allow proper caramelization.

Roast Until Tender

Roast for 25–30 minutes, stirring halfway through, until vegetables are fork-tender with golden, lightly charred edges.

Finish and Serve

Remove from the oven, let cool slightly, then garnish with freshly chopped parsley before serving warm.

Recipe Notes & Tips

Do Not Overcrowd the Pan – Crowding traps steam and prevents browning.
Harissa Heat Levels Vary – Taste your harissa first and adjust quantity accordingly.
Cut Size Matters – Larger florets take longer; keep pieces consistent.
Mid-Roast Stirring – Ensures even color and prevents burning.
Oil Distribution Is Key – Insufficient oil leads to dry, uneven roasting.

Why This Recipe Works

High-temperature roasting encourages Maillard browning, enhancing sweetness and depth in vegetables while concentrating flavor. Olive oil acts as a heat conductor, while harissa’s blend of chili, garlic, and spices infuses complexity without extra steps. The variety of vegetables provides contrasting textures and moisture levels, preventing dryness.
