Ingredients
- 1 cup broccoli florets
- 1 cup cauliflower florets
- 1 bell pepper, sliced
- 1 zucchini, sliced
- 1 small red onion, sliced
- 1½ tablespoons olive oil
- ½ teaspoon salt
- ½ teaspoon garlic powder
- ¼ teaspoon black pepper
Optional notes:
- Any bell pepper color works here.
- If your broccoli or cauliflower florets are large, cut them down so everything cooks evenly.
Instructions
- Preheat the oven
Set your oven to 425°F. This higher heat is key for roasting instead of steaming. Line a large baking sheet with parchment paper or foil for easy cleanup. - Prep the vegetables
Add the broccoli, cauliflower, bell pepper, zucchini, and red onion to a large bowl. Look for similar-sized pieces—this helps everything finish cooking at the same time. - Season and toss
Drizzle the olive oil over the vegetables. Sprinkle with salt, garlic powder, and black pepper. Toss well until everything is lightly coated and glossy, with no dry spots. - Spread on the pan
Transfer the vegetables to the baking sheet and spread them into an even layer. Make sure they’re not crowded—this is where the roasting magic happens. - Roast
Place the pan in the oven and roast for 20–25 minutes. Halfway through, stir the vegetables so they brown evenly. You’re looking for tender centers and lightly golden edges. - Finish and serve
Remove from the oven when the vegetables are fork-tender and slightly caramelized. Taste and add a pinch of extra salt if needed. Serve warm.

Why This Recipe Works
- One pan means minimal cleanup
- High heat brings out natural sweetness

Variations
- Cheesy finish: Sprinkle grated Parmesan over the vegetables during the last 5 minutes of roasting.

- Storage & Reheating
- Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheat in a 400°F oven for 5–8 minutes to bring back some crisp edges.
- The microwave works too, though the vegetables will be softer.
FAQ
Can I use frozen vegetables?
Fresh vegetables work best for roasting. Frozen vegetables release more moisture and won’t brown the same way.
Why are my vegetables soggy?
They were likely overcrowded on the pan or the oven temperature was too low. Give them space and use high heat.
Can I prep these ahead of time?
Yes. You can chop the vegetables up to a day in advance and store them in the fridge until ready to roast.
What can I serve this with?
These roasted vegetables pair well with chicken, fish, pasta, or even as a simple grain bowl topping.
