Roasted Butternut Squash

Roasted butternut squash emerges from the oven with caramelized, crispy edges and creamy insides, no steaming or mushiness. The key is cutting it into evenly sized pieces, drying them completely, and spreading them out so hot air circulates around every piece.

Ingredients for Roasted Butternut Squash

Butternut squash becomes tender and sweet when roasted, developing brown, caramelized edges. Olive oil helps the squash brown and prevents sticking. Kosher salt and black pepper season it throughout, while fresh thyme adds a subtle herbal note that complements the squash’s natural sweetness.

Why This Roasted Butternut Squash Works

Butternut squash has high water content, so it will steam if crowded on the pan or if the oven temperature is too low. A hot oven (425°F) and plenty of space between pieces lets water evaporate quickly, so the exposed surfaces brown instead. The pieces cook through at the same time they caramelize.

Patting the squash dry after cutting removes surface moisture that would otherwise trap steam. Tossing with oil and salt before roasting seasons the pieces evenly and helps them brown all over. Stirring halfway through ensures even cooking and browning on all sides.

Mistakes To Avoid

Cutting the pieces too small makes them cook so fast they never brown, or they burn before the insides soften. Pieces larger than 1 inch also cause trouble: the outsides brown too much before the centers get tender. Cut everything to the same size so it all finishes at once.

Squash that is not patted dry will steam rather than roast, turning soft and pale with no caramelization. The moisture on the surface prevents the oil from making good contact with the heat. Dry it thoroughly before oiling and roasting.

Crowding the pan traps steam around the squash and stops browning, leaving the pieces pale and limp. Even if you have only one large baking sheet, use two sheets instead of layering the squash two deep. Space and hot air are what make roasted squash good.

Roasting at a low temperature (below 400°F) steams the squash instead of roasting it, no matter how long it sits in the oven. The oven must be hot enough that water on the surface evaporates faster than new moisture can reach it. Use 425°F or higher.

Ingredients

• 1 butternut squash, about 3 pounds
• 3 tablespoons olive oil
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 2 sprigs fresh thyme

Step-by-step Instructions

1. Heat the oven to 425°F (220°C) with a rack in the upper third.
2. Halve the butternut squash lengthwise and scoop out the seeds with a spoon.
3. Cut each half into 1-inch pieces, removing the skin with a sharp knife or vegetable peeler.
4. Pat the squash pieces dry with paper towels.
5. Toss the squash with olive oil, salt, and pepper in a large bowl.
6. Spread the squash in a single layer on a rimmed baking sheet with space between each piece, and scatter the thyme sprigs over the top.
7. Roast for 20 minutes at 425°F (220°C).
8. Stir the squash and flip the pieces so a new side faces down, then roast for another 20 minutes until the edges are deep golden brown and a fork easily pierces the thickest part.
9. Remove from the oven and let rest for 5 minutes before serving.
