Roast pumpkin & red onion FAQ:

What is the best pan size to use for roasting?

A large baking sheet or pan is recommended, ideally around 18x13 inches. This allows the pumpkin and onions to spread out evenly, promoting even roasting and caramelization.

How can I tell if the pumpkin is done roasting?

The pumpkin is done when it is tender and slightly caramelized around the edges, typically after 25-35 minutes at 400°F (200°C). A fork should easily pierce the flesh.

Can I make substitutions for the rosemary?

Yes, you can substitute rosemary with other herbs like thyme or sage, which will also complement the flavors. Adjust the amount according to your taste preference.

How should I store leftovers?

Store leftover roasted pumpkin and red onion in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven or microwave before serving.

What type of pumpkin is best for roasting?

Sugar pumpkins or other varieties like butternut squash work well due to their sweetness and texture when roasted. Avoid using ornamental pumpkins, as they may not have the best flavor.
