Ingredients You’ll Need

How to Make Garlic Roasted Vegetables

This recipe is incredibly simple.

Step 1: Prepare the Vegetables

Cut:

Potatoes into bite-sized pieces
Carrots into even chunks
Green beans in half

Keeping vegetables similar in size helps them roast evenly.

Step 2: Season the Potatoes & Carrots

In a large bowl toss:

Potatoes
Carrots
Olive oil
Thyme
Rosemary
Salt
Pepper

Spread onto a baking sheet in a single layer.

Step 3: Roast

Bake at 400°F for about 20 minutes.

This gives the potatoes and carrots a head start since they take longer to cook.

Step 4: Add Green Beans & Garlic

Toss green beans with olive oil and add them to the pan along with the garlic.

Mix everything gently and spread evenly again.

Step 5: Finish Roasting

Roast another 20 minutes until:

Potatoes are golden
Carrots are tender
Green beans are lightly blistered
Garlic is fragrant

Serve warm and enjoy!

Tips for Perfect Roasted Vegetables

Cut Even Sizes

Uniform pieces roast more evenly.

Don’t Crowd the Pan

Vegetables need space to roast instead of steam.

Use High Heat

400°F gives the vegetables beautiful caramelization.

Add Green Beans Later

Green beans cook faster than potatoes and carrots.

Use Fresh Herbs

Fresh rosemary and thyme make a huge flavor difference.

Delicious Variations

Add Parmesan Cheese

Sprinkle freshly grated parmesan over the vegetables before serving.

Make It Spicy

Add red pepper flakes or cayenne.

Try Different Vegetables

Add:

Brussels sprouts
Zucchini
Cauliflower
Sweet potatoes
Bell peppers

Add Lemon

Fresh lemon juice brightens the flavors beautifully.

What to Serve with Roasted Vegetables

These vegetables pair perfectly with:

Roasted chicken
Steak
Salmon
Pork chops
Pasta dishes
Holiday dinners

They’re versatile enough to go with almost anything.

Storage & Reheating

Refrigerator

Store leftovers in an airtight container for up to 4 days.

Reheating

Reheat in:

Oven
Air fryer
Skillet

for the best texture.

Microwaving works too, though the vegetables won’t stay as crispy.
