Sheet pan roasted mixed vegetables deliver deep caramelization, bold savory flavors, and a satisfying contrast of crisp edges and tender centers — nothing like limp frozen blends or steam-in-bag sides. This method uses high heat and staggered timing so each vegetable finishes perfectly: denser root vegetables roast first, then quicker-cooking broccoli and Brussels sprouts join the pan so everything is crisp-tender. A finishing drizzle of Italian vinaigrette brightens the dish and ties the flavors together.
Here’s Why This Mixed Roasted Vegetable Recipe Works
Staggered roasting preserves texture: Start with hardier vegetables such as potatoes and carrots so they have time to soften and caramelize. Add broccoli and Brussels sprouts later to avoid limp, overcooked florets.
One-sheet pan maximizes caramelization: Spreading vegetables in a single layer allows hot air to circulate and encourages browning rather than steaming. The result: concentrated flavor and appealing roasted color.
Fennel contributes subtle sweetness: When roasted, fennel’s licorice notes mellow and concentrate into a gentle sweetness that complements earthy roots and bitter greens.
Vinaigrette finishes with brightness: A quick drizzle of Italian vinaigrette after roasting adds acidity and herb-forward lift, making the vegetables feel lively and balanced.
Ingredient Notes
Potatoes: Use small waxy varieties such as Yukon Gold or small red potatoes. They roast to creamy interiors and crisp exteriors. Cut to uniform sizes — halves or quarters depending on potato size — so they cook evenly.
Fennel: If you’ve not cooked with fennel before, roasting is a forgiving introduction. The tough anise edge softens and becomes lightly sweet and caramelized. Leave the core intact when cutting wedges to help each piece hold together while roasting.
Brussels sprouts and broccoli: Add these later in the bake. They need less time than potatoes and carrots to reach tender-crisp doneness. Halve small sprouts and cut broccoli into 2-inch florets for even roasting.
Red onion: Red onion roasts down to jammy, sweet bites that add rounded flavor and a touch of sharpness that cuts the richness of roasted roots.
Italian vinaigrette: A finishing 1/4 cup of vinaigrette brings acidity and herb notes that brighten and unify the dish. Homemade vinaigrette is easy and flavorful, but a quality store-bought option works well too.
These roasted vegetables are an ideal side for a range of mains. They pair beautifully with simple fish, roasted or broiled pork chops, baked chicken breast, or any protein where you want an easy, vegetable-forward accompaniment. Make a double batch for meal prep — they hold up well served warm or at room temperature.
Recipe Tips
Cut uniformly: Aim for similar-sized pieces so everything finishes at the same time. This is most important for potatoes and carrots.
Don’t crowd the pan: Use a large rimmed sheet pan or two pans. Overcrowding traps steam and prevents browning.
Olive oil matters: Use enough oil to coat the vegetables so they sizzle in the oven, but don’t drown them. A light, even coating encourages crisp edges.
Season twice: Add a first seasoning before roasting and check for a small adjustment of salt and pepper after adding the quicker-cooking vegetables and before the final roast.
Flip halfway: Turning vegetables with a spatula halfway through roasting promotes even browning and deeper caramelization.
Serve warm or room temperature: Roasted vegetables are flexible — perfect right away or later for lunches and meal prep.
Use what you have: This recipe is forgiving. Swap or omit vegetables according to seasonality and preferences as long as you respect relative cooking times.
Optional finish: A handful of chopped parsley or fresh thyme sprinkled after roasting adds color and a fresh contrast to caramelized flavors.

Oven Roasted Mixed Vegetables
A hearty sheet-pan medley roasted in stages for perfect texture, finished with tangy Italian vinaigrette. Golden-browned vegetables with crisp edges and tender centers.
Ingredients
- 6 to 8 baby potatoes, cut in half
- 2 to 3 carrots, peeled and cut into 1-inch pieces
- 1 red onion, cut into wedges
- 1 fennel bulb, trimmed and cut into 6 wedges, core left intact
- Extra virgin olive oil, divided
- Salt and pepper
- 4 to 6 Brussels sprouts, halved
- 1 head broccoli, cut into 2-inch florets
- 1/4 cup Italian vinaigrette, homemade or store-bought
Instructions
- Preheat the oven to 425°F (220°C). Line a large rimmed sheet pan with parchment paper for easier cleanup and to help prevent sticking.
- Place the potatoes, carrots, red onion, and fennel in the center of the pan. Drizzle with part of the olive oil and spread into a single layer. Season with salt and pepper. Roast until they are just beginning to become tender and well browned, about 40–45 minutes, flipping once halfway through for even browning.
- While the root vegetables begin to roast, toss the Brussels sprouts and broccoli in a bowl with the remaining olive oil and a pinch of salt and pepper.
- Remove the pan from the oven and create space by shifting the first batch of vegetables. Add the prepared Brussels sprouts and broccoli in a single layer. Sprinkle with a little more salt and pepper, then return the pan to the oven and roast an additional 15–20 minutes, or until all vegetables are browned at the edges and tender.
- Transfer the roasted vegetables to a serving platter and drizzle with Italian vinaigrette. Toss gently to coat and serve warm or at room temperature. Optionally garnish with chopped parsley or thyme.
Notes
Cut vegetables evenly, stage them by cooking time, and avoid overcrowding the pan to ensure roasting rather than steaming. Flip once for best caramelization and finish with vinaigrette for brightness.
