What you will need

This recipe uses 5 simple ingredients that you can find at any grocery store:

  • 2 cups butternut squash peeled and cubed
  • 2 tbsp water
  • 1 tbsp butter
  • 0.5 tsp cinnamon
  • 1 tbsp brown sugar

Step by step instructions

Step 1: Cube Squash

Peel the butternut squash and cut it into roughly 1-inch even cubes so they all cook at the same rate in the microwave.

Step 2: Add Water and Cover

Place squash cubes in a microwave-safe bowl with 2 tablespoons of water and cover tightly with a microwave-safe lid or plastic wrap.

Step 3: Microwave

Microwave on high for 6 minutes until the squash is fork-tender, stirring once at the 3-minute mark.

Step 4: Season and Serve

Drain any water and toss immediately with butter, brown sugar, and cinnamon until evenly coated. Serve warm.
