-
Prepare the Squash: Start by cutting the acorn squash in half and scooping out the seeds. This step is key for ensuring even cooking and flavor absorption.

Expert Tips for Instant Pot Acorn Squash
-
Choose Ripe Squash: Look for acorn squash with a deep green color and firm texture. Soft spots may indicate overripeness or spoilage, resulting in a less tasty dish.
-
Prep for Even Cooking: Make sure to cut the squash halves evenly. Uneven halves can lead to one side being overcooked while the other remains firm.
-
Season After Cooking: If you’re uncertain about flavors, cook the squash plain and add seasonings afterward. This way, you can control the sweetness or savoriness level to your liking.
-
Watch the Water: Always include a full cup of water in the Instant Pot. Insufficient liquid can lead to scorching and undesirable flavors in your Instant Pot acorn squash.
-
Experiment with Flavors: Don’t hesitate to try different spices or herbs! Adding nutmeg or cinnamon can create a warm, cozy flavor, perfect for fall.
-
Check Tenderness: After cooking, use a fork to test the tenderness. If it’s not soft enough, you can quickly return it to the Instant Pot for a few more minutes.
