Ingredients
Method
- Preheat the oven to 425°F. Peel and cut 2 pounds butternut squash into uneven 1-inch cubes. Work at room temperature and finish within 10 minutes. Toss the cubes with 2 tablespoons olive oil, salt, black pepper and thyme using your hands in a folding motion until coated. You'll see a glossy orange surface with herbs clinging to the squash pieces. The smell becomes earthy and fresh from the thyme. Skip this coating step and the seasoning won't stick evenly across the cubes. Coat each cube evenly, the oil helps heat transfer and browning.

- Spread the seasoned 2 pounds butternut squash cubes in a single layer and roast at 425°F for 20 to 25 minutes. Flip the cubes halfway through with a spatula using a gentle turning motion so each side touches the heat. The edges become deep golden and you'll notice a roasted aroma after about 15 minutes. The surfaces should look slightly crisp while the centers stay tender. Crowd the pan and the squash steams instead of caramelizing. Roast at 425°F without crowding, dry heat creates better caramelization.

- Return the roasted 2 pounds butternut squash cubes to the pan and roast at 425°F for another 5 minutes after adding fresh thyme leaves. Gently toss the cubes with a turning motion so the herbs spread over the warm surfaces. You'll see darker caramelized corners and a glossy finish across the squash. The aroma becomes sweeter as the natural sugars deepen. Remove them before 30 minutes total or the edges can turn bitter. Finish with a short final roast, concentrated sugars create the deeper flavor.

- Transfer the roasted 2 pounds butternut squash cubes onto a white serving plate at room temperature after resting for 5 minutes. Arrange the pieces loosely by hand and keep some caramelized sides facing upward for texture. (I tested serving it immediately once and the steam softened the edges. The short rest kept the roasted surface better.) You'll see uneven golden colors and small herb flecks across the plate. Rest 5 minutes before serving, the surface texture settles after roasting.

Notes
Store the roasted squash in an airtight glass container in the refrigerator for up to 4 days. You can freeze it for up to 3 months by spreading portions into freezer bags and removing excess air before sealing. Thaw frozen squash overnight in the refrigerator before reheating. Reheat the squash at 400°F for 10 to 15 minutes until the edges warm and regain some roasted texture. Add a teaspoon of olive oil and fresh thyme after reheating if the surface looks dry. Discard leftovers that develop a sour smell, slimy texture or unusual discoloration.
