Ingredients

Vegetables:
- 1 medium zucchini, sliced into rounds
- 1 red bell pepper, sliced into strips
- 1 yellow bell pepper, sliced into strips
- 1 small red onion, sliced
- 1 cup broccoli florets
- 1 cup cauliflower florets
- 1 cup cherry tomatoes, halved
For Seasoning:
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- Salt and pepper to taste
- 1 tablespoon fresh parsley (optional, for garnish)
Instructions

Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This high temperature will help the vegetables roast and caramelize, bringing out their sweetness.
Step 2: Prepare the Vegetables
Wash and slice all your vegetables. Make sure the pieces are uniform in size so that they cook evenly. Place them on a large sheet pan.
Step 3: Season the Vegetables
Drizzle the olive oil over the vegetables. Sprinkle the garlic powder, dried thyme, rosemary, salt, and pepper on top. Toss everything together with your hands to make sure the seasoning is evenly distributed.
Step 4: Roast the Vegetables
Place the sheet pan in the preheated oven. Roast the vegetables for about 25-30 minutes. Halfway through, take the pan out and toss the vegetables to ensure even roasting. The vegetables should be golden brown and tender when done.
Step 5: Garnish and Serve
Once roasted, take the pan out of the oven. Garnish with freshly chopped parsley, if desired. Serve immediately as a side or as a main dish with your choice of protein.
Top Tips
- Cut vegetables evenly: To ensure they cook evenly, cut your vegetables into similar sizes. Smaller pieces will cook faster, while larger pieces may take a bit longer.
- Use parchment paper: Lining your baking sheet with parchment paper makes cleanup easier and prevents the vegetables from sticking.
- Adjust seasoning: Feel free to experiment with other herbs and spices like paprika, cumin, or oregano to suit your taste.
- Don’t overcrowd the pan: If you’re making a large batch, use two sheet pans. Overcrowding the pan can lead to steaming rather than roasting.
- Check for doneness: Vegetables can vary in size, so check for doneness by piercing them with a fork. They should be tender but not mushy.
Variations
- Add more veggies: You can include vegetables like carrots, asparagus, or Brussels sprouts in the mix for added variety and nutrition.
- Spicy version: Add a pinch of red pepper flakes or chili powder to give the dish a little kick.
- Cheese lovers: Sprinkle some Parmesan cheese or feta cheese over the roasted vegetables for extra flavor.
- Make it a meal: Add roasted chicken, shrimp, or tofu for a complete low-carb meal.
- Sweet touch: You can also add a few slices of sweet potatoes, but remember that sweet potatoes are higher in carbs.
