Ingredients List
- 1 large bag (about 32 oz) Costco mixed vegetables (carrots, broccoli, cauliflower, bell peppers)
- 3 tbsp olive oil (or substitute avocado oil)
- 1 tsp garlic powder (fresh minced garlic optional)
- 1 tsp smoked paprika (or sweet paprika)
- tsp salt (adjust to taste)
- tsp black pepper
- Optional: fresh thyme or rosemary sprigs
Equipment Needed
One large rimmed metal sheet pan works best to spread heat evenly. Line it with parchment paper or a silicone baking mat to keep cleanup easy. Preheat your oven to 425F before starting.
Choosing Quality Ingredients
Look for fresh vegetable mixes at Costco without bruises or soft spots. While organic is a bonus, freshness is most important. Use extra virgin olive oil for a richer aroma and flavor. Fresh herbs should be bright and fragrant to add the final touch.
Step-by-Step Instructions
Prepare Your Vegetables
Rinse any loose vegetables not pre-washed, then pat them dry thoroughly. Cut larger pieces into uniform bite-sized chunks for even cooking. If using baby carrots, no peeling is needed, which speeds up prep.
Roast at 425F for 25 Minutes
Place the vegetables in a large bowl. Drizzle with olive oil and sprinkle garlic powder, smoked paprika, salt, and black pepper. Toss to coat evenly. Spread them out on the lined pan in a single layer, leaving some space between pieces.
Roast in the preheated oven at 425F for 25 minutes. Halfway through, around 12 minutes, stir gently to promote even browning and prevent burning.

Add Final Touches
Remove the pan once vegetables have golden edges and a tender interior. For extra aroma, sprinkle fresh thyme or rosemary before serving. Avoid adding salt before roasting to keep the veggies crisp.
Serve Hot or Store Properly
Serve the roasted vegetables fresh and hot to enjoy their crispy texture. For leftovers, cool them slightly, then store in airtight containers in the refrigerator.
