Kitchen Tools You’ll Need

Large baking sheet
Parchment paper (optional but recommended)
Large mixing bowl
Sharp knife & cutting board
Measuring spoons
Spatula or tongs

Simple tools. Big flavor.

Step-by-Step Preparation

Total Time: 30–35 Minutes

Prep Time: 10 minutes
Cook Time: 20–25 minutes

1. Preheat the Oven

Preheat your oven to 220°C (425°F).

High heat is key to getting those crispy golden edges!

2. Prepare the Vegetables

Halve baby potatoes.
Slice carrots into even sticks (about the same thickness as the potatoes).
Trim green beans.

Pro Tip: Cut vegetables evenly so they roast at the same rate.

3. Season Everything

In a large bowl, combine:

Potatoes
Carrots
Green beans
Olive oil
Garlic
Rosemary
Thyme
Salt and pepper

Toss thoroughly until every piece is lightly coated.

The herbs should cling to the vegetables — that’s where the flavor magic begins.

4. Spread on Baking Sheet

Spread the vegetables in a single layer.

Important: Do NOT overcrowd the pan.
Crowding = steaming.
Space = crispiness.

Use two pans if needed.

5. Roast to Golden Perfection

Roast for 20–25 minutes, flipping halfway through.

You’ll know they’re done when:

Potatoes are fork-tender
Carrots are caramelized
Green beans are slightly blistered
Edges are golden brown

If you love extra crispiness, broil for the last 2 minutes.

6. Finish & Serve

Optional but delicious:

A squeeze of fresh lemon juice
A sprinkle of parmesan
A pinch of flaky sea salt

Serve immediately while hot and crisp.

Expert Tips & Mistakes to Avoid

✔ For Extra Crispy Potatoes

Parboil potatoes for 5 minutes before roasting.
Use a metal baking sheet (not glass).
Don’t skip flipping halfway.

❌ Avoid These Common Mistakes

Too much oil: Makes veggies soggy.
Low oven temperature: Leads to soft, pale vegetables.
Uneven cuts: Causes some pieces to burn while others undercook.
