Expert Tips for the Best Oven Roasted Butternut Squash

Want to take your oven Roasted Butternut Squash to the next level? Here are a few of my favorite tips and tricks:

  • Selecting the best squash: When you’re at the store, look for a butternut squash that feels heavy for its size. The skin should be firm and free from blemishes or soft spots.
  • Adjusting cooking time: Cooking times can vary depending on the size of your squash and your oven. Keep an eye on it, and test for tenderness with a fork. If it’s not quite there, just add a few more minutes.
  • Choosing the right oil: I usually use olive oil, but avocado oil works great too.

Variations and Substitutions

Want to mix things up? Here are a few ideas to get you started:

VariationDescription
Sweet and SpicyAdd a pinch of cayenne pepper and a drizzle of maple syrup.
Savory with HerbsUse rosemary, thyme, and sage instead of Italian seasoning.
Balsamic GlazedDrizzle with balsamic glaze during the last 5 minutes of roasting.
Cinnamon and NutmegSprinkle with cinnamon and nutmeg for a warm, autumnal flavor.

Common Mistakes to Avoid

Even though this recipe is super simple, it’s helpful to know about some common mistakes and how to avoid them:

  • Overcrowding the pan: If you overcrowd the pan, the squash will steam instead of roast. Make sure to roast in a single layer, and if needed, use two baking sheets or roast in batches.
  • Not roasting long enough: Make sure the squash is very tender and easily pierced with a fork. If it’s still firm, it needs more time in the oven.
  • Burning the edges: Keep an eye on the squash during the last few minutes of roasting. If the edges start to burn, lower the oven temperature or tent the baking sheet with foil.
