How to Make Hasselback Butternut Squash with Garlic Butter

Prep & Hasselback Slicing

Preheat oven to 400°F (200°C). Peel squash, halve lengthwise, remove seeds. Place halves flat side down. Make thin slices almost through—use chopsticks beside squash as a guard so you don’t slice all the way through.

First Roast

Place on a baking tray lined with parchment. Drizzle olive oil, season with salt and pepper. Roast ~30 minutes until just tender.

Garlic Butter Sauce & Basting

While squash roasts, melt butter over medium heat. Add garlic, thyme, chili flakes until fragrant. Remove squash, fan open slices and brush garlic butter generously. Roast another 20-25 minutes, basting halfway. Drizzle honey near the end so edges caramelize.

  • Can roast ahead then reheat at 350°F for 10-15 minutes before serving.
