How to Make Mashed Butternut Squash
Making this dish is as easy as pie! Just follow these simple steps, and you’ll have a bowl of creamy, dreamy squash in no time.
Step 1: Boil the Squash and Garlic
- First, put 2 pounds of cubed butternut squash and 4 peeled garlic cloves into your large pot. Cover them with water and add a little salt. Turn the heat up and bring it all to a boil.
- Let it cook for about 15-20 minutes. You’ll know it’s ready when the squash is super soft if you poke it with a fork.
Step 2: Drain Well
- Now, carefully pour the squash and garlic into your colander in the sink. Let it sit for a minute or two to let all the steam escape.
- This is my secret trick! It helps get rid of extra water so your mash isn’t soupy. Don’t skip this step!
Step 3: Mash and Mix
- Put the drained squash and garlic back into the warm pot. Add 4 tablespoons of soft, unsalted butter, 1 tablespoon of olive oil, 1/2 teaspoon of sea salt, and 1/4 teaspoon of black pepper. Now for the fun part!
- Use your immersion blender to whip it all together until it’s perfectly smooth and creamy.
Step 4: Serve and ENJOY!
- Give your mashed squash a little taste. Does it need more salt? Add it now! Then, scoop that yummy mash into a serving bowl.
- I love to sprinkle some fresh chives on top for a pop of color. Serve it up warm and watch everyone ask for seconds.

Tips for the Best Mashed Butternut Squash
Want to make the BEST squash ever? Here are a few of my favorite little tricks that will knock your socks off.
- Drain it Well: Seriously, let the squash steam dry for a minute. No one likes watery mash!
- Use an Immersion Blender: This is my secret weapon for getting that perfectly smooth, whipped texture.
- Don’t Overboil: Cook the squash until it’s just fork-tender. If it gets too mushy, it loses flavor.
- Taste and Season: Always give it a taste at the end. You might want a little more salt or pepper.
- Warm Your Butter: Using softened or melted butter helps it mix in evenly and quickly.
Variations and Substitutions

- Herb it Up: Fresh sage or thyme tastes amazing with squash. Just chop them up and stir them in.
