Preheat the Oven:

1. Step 1: Preheat your oven to 425°F (218°C). Line a large baking sheet with parchment paper.

Prepare the Vegetables:

1. Step 1: Wash and cut all vegetables. Halve or quarter potatoes to uniform size, slice carrots and peppers, and chop onions and broccoli into similar bite-sized pieces.

Mix the Seasoning:

1. Step 1: In a large mixing bowl, combine olive oil, garlic, rosemary, thyme, salt, and pepper.

Toss Everything Together:

1. Step 1: Add the chopped potatoes and vegetables to the bowl and toss until all pieces are well coated in the oil and seasoning mixture.

Arrange on Baking Sheet:

1. Step 1: Spread the seasoned vegetables in a single layer on the prepared baking sheet. Use two sheets if necessary to avoid overcrowding.

Roast the Vegetables:

1. Step 1: Bake for 35–40 minutes, flipping halfway through, until potatoes are golden and fork-tender, and veggies are lightly crisped.

Finish and Serve:

1. Step 1: Remove from oven and garnish with fresh parsley and lemon juice or zest. Add optional parmesan or red pepper flakes if desired. Serve hot.
