The Secrets to Perfect Roasting

The difference between pale, steamed vegetables and perfectly golden-brown, caramelized ones comes down to a few simple but crucial techniques. This recipe for Roasted Potatoes and Tomatoes has them all built in.

  1. The Hot Sheet Pan: This is the number one secret to a crispy exterior. By preheating your empty baking sheet in the oven, it gets screaming hot. When you spread your potatoes onto this hot surface, they begin to sear and crisp up immediately, preventing them from steaming in their own moisture.
  2. High Heat: Roasting at a high temperature of 450°F is essential. This high heat cooks the vegetables quickly, making the insides tender and fluffy while creating that desirable browned and crispy outside.
  3. The “Burst Tomato” Sauce: As the cherry tomatoes roast under the high heat, their skins blister and they burst, releasing their sweet, acidic juices. These juices mingle with the olive oil, garlic, and rosemary right on the pan, creating an incredible, rustic “pan sauce” that coats every piece of potato.
  4. Whole Aromatics: We use whole rosemary sprigs and smashed (but not minced) garlic cloves. This is a smart technique for high-heat roasting, as it allows the aromatics to infuse the entire dish with their flavor without the risk of burning, which finely minced garlic would do.

The Key Ingredients for Your Roasted Potatoes and Tomatoes

This recipe uses a handful of simple, classic, and powerful ingredients.

  • Red-Skinned Potatoes: These are a fantastic choice for roasting. They are a “waxy” potato, which means they have less starch and hold their shape beautifully when cooked, all while developing a wonderfully creamy interior. Yukon Gold potatoes are another excellent choice.
  • Cherry or Grape Tomatoes: These sweet little tomatoes are perfect for this dish. They provide a burst of sweet, juicy acidity that balances the starchy potatoes.
  • Fresh Rosemary and Garlic: The classic, aromatic duo that perfumes the entire dish with a rustic, savory flavor.
  • Good Olive Oil: Using a good-quality olive oil will add a delicious, fruity flavor to your Roasted Potatoes and Tomatoes.

Step-by-Step Guide to Your Roasted Potatoes and Tomatoes

This easy, one-pan side dish comes together with minimal hands-on time.

  1. Preheat Your Oven and Pan: Place a large, rimmed baking sheet in the oven. Preheat the oven to a hot 450°F.
  2. Prepare the Vegetables: Cut your red-skinned potatoes lengthwise into eighths, creating uniform wedges. In a large bowl, toss the potato wedges with 2 tablespoons of olive oil, the whole cherry tomatoes, the 3 sprigs of fresh rosemary, and the 3 smashed garlic cloves. Season everything generously with kosher salt and freshly ground black pepper.
  3. The First Roast: Carefully remove the hot baking sheet from the oven. Spread the potato and tomato mixture out on the hot pan in a single, even layer. It’s important not to overcrowd the pan. Place the potatoes cut-side down for the best initial sear. Roast for 15 minutes.
  4. Flip and Finish: After 15 minutes, remove the pan from the oven. Use a spatula to flip the potato and tomato mixture over. Return the pan to the oven and roast for another 10 more minutes. Your Roasted Potatoes and Tomatoes are done when the potatoes are tender and golden brown, and the tomatoes have burst.
  5. Serve: You can serve this delicious side dish hot, right from the pan. Before serving, you can remove the cooked rosemary sprigs and garlic cloves, or leave them in for a rustic presentation.

Frequently Asked Questions (FAQs)

My potatoes are soggy and pale, not crispy. What did I do wrong?

This is almost always caused by one of two things: you didn’t preheat the baking sheet, or you overcrowded the pan. The potatoes need to be in a single layer with some space between them to allow the steam to escape so they can roast properly.

Can I use other vegetables?

Yes, absolutely! Chunks of red onion, bell peppers, or zucchini would all be fantastic additions to these Roasted Potatoes and Tomatoes. Just be sure to cut them to a size where they will cook in the same amount of time as the potatoes.

How do I store and reheat leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 4 days. For the best result, reheat them on a baking sheet in a 400°F oven or in an air fryer for a few minutes until they are warmed through and have crisped up again.
