Ingredients
cooking spray
10 medium potatoes, peeled and cubed, or more to taste
4 large carrots, peeled and cut into 1/2-inch chunks
1 medium onion, cut into 1/4-inch slices
⅓ cup balsamic vinegar
¼ cup unsalted butter, melted
8 sprigs fresh thyme
1 teaspoon minced garlic
1 teaspoon salt
½ teaspoon ground black pepper
Directions
1
Preheat the oven to 425 degrees F (220 degrees C). Coat a 9x13-inch baking pan with cooking spray.
2
Mix potatoes, carrots, onion, balsamic vinegar, butter, thyme, garlic, salt, and pepper together in a large glass bowl. Spread mixture into the prepared pan in an even layer. Cover with foil.
3
Roast in the preheated oven, giving the pan a shake every 15 minutes to ensure even cooking, for 45 minutes.
4
Remove foil and continue to roast, uncovered, stirring occasionally, for another 30 minutes.
Notes
You can use 1 teaspoon of dried thyme instead of fresh.
Balsamic vinegar might stain plastic, so use a glass bowl when mixing together.
