The BEST Mashed Butternut Squash – Simple and Healthy

This savory Mashed Butternut Squash recipe is my go-to healthy side dish in the fall. It is easy to make, and comes out wonderfully rich, creamy, and flavorful every time! The butternut squash is slowly roasted in the skin then mashed with dairy-free butter, milk, or stock and topped with fresh herbs. It makes a delicious addition to any meal, especially for the holidays!

This mashed butternut squash is an old family recipe that I made a little bit healthier while still keeping it creamy and flavorful. It is a nutritious side dish that is super low maintenance and lighter than traditional mashed sweet potatoes, which is another family favorite.

In this recipe, we roasted the butternut squash slowly right in the skin allowing the natural sugars to become released forming a golden, tender, and caramelized result. Then it is scooped, mashed and combined with butter, milk, garlic, and herbs resulting in the most delicious savory mashed butternut squash you will ever have!

It is an amazing vegetable mash paired with some roasted pork tenderloin or chicken for a complete and hearty weeknight fall dinner that the whole family will love!

Is it better to bake or steam butternut squash?

The preferred method is to roast the butternut squash in its skin because it will become more flavourful, and nutritious and it is less labor intensive.  It may take slightly more time to cook but it is totally worth it!

Boiling/steaming the squash will require you to peel and cut the squash and it will remove some of the flavor and nutrition in the squash as well.  Now if you are short on time then boiling the squash is much faster and will take you about 15 minutes once you peel and cut the squash into cubes.  

Note: Keep in mind that you do not need to do much to squash for it to be delicious since it is naturally nutty and sweet with a slight buttery flair to it. Hence the name “Butter-Nut-Squash”.

Ingredients and Substitutions

No long list of ingredients for this delicious savory mashed butternut squash. Here is what you’ll need:

• Whole butternut squash – butternut squash is versatile, inexpensive, and has a wonderful nutty flavor that really comes out when roasted. You will need around a 3-3.5 pound squash which will make enough for about 4-6 people. Substitutions: You can use any winter squash such as honeynut, Hubbard, buttercup, or acorn squash. However, this recipe was tested specifically using the butternut variety.
• Olive oil – extra virgin olive or avocado oil is used to roast the squash.
• Garlic – fresh minced garlic is best but you could use garlic powder or garlic paste if needed. 
• Milk – unsweetened non-dairy milk. I used almond milk. Substitutions: Coconut milk and soy milk work great! Stock can also be used or a blend of both stock and milk.
• Butter – I used vegan butter but regular butter is fine too. This gives the squash amazing flavor and creaminess, making it smooth and luscious. Substitutions: Any type of butter will work, so use your favorite or whatever you have on hand.
• Fresh herbs – fresh rosemary and chives give this mashed squash so much flavor but you can also use dried herbs as well. Substitutions: Any fresh herbs go great with squash like sage, thyme, rosemary, or chives.
• Kosher Salt and black pepper – enhance all of the flavors.

How to make savory Mashed Butternut Squash

This is one of the best and simplest ways to cook butternut squash that you are going to love!

How do you cut butternut squash for roasting?

It is very easy to prepare butternut squash to roast it. Here are some detailed tips and step-by-step photos for how to cut butternut squash for roasting. I included photos and a summary below.

Pro Tip: For a smoother more velvety texture, use a food processor or blender. If you prefer a rustic, chunky texture, use a potato masher, like I did.

Recipe Tips and Variations

1. Creaminess: Add a splash of milk, cream, or coconut milk to make the mash creamier. A dollop of butter or a drizzle of olive oil can also enhance the texture and flavor.
2. Seasoning: While salt and pepper are essential, consider adding a pinch of nutmeg, cinnamon, or ground ginger. These spices complement the natural sweetness of butternut squash.
3. Sweetness: If you prefer a sweeter mash, drizzle in a bit of maple syrup or honey. You can also brush the squash with maple syrup and sprinkle some cinnamon on it before you roast it for a sweeter flavor to your squash. Note: If you are making it sweeter rather than savory then skip the garlic and herbs.
4. Roasting: The squash can be roasted on a baking sheet or in a larger casserole dish. I recommend roasting it cut side up for a nice golden caramelized butternut squash. If you prefer to roast it cut-side down then you can do that as well. The results are very similar either way. You want to cook it until it is scoopable with a spoon so you may need to cook it longer than recommended depending on the size squash you are using.

Do I need to peel the butternut squash before roasting it?

In this recipe, we roast the squash in the skin so it is not necessary to peel it.

Serving Suggestions

Mashed butternut squash is a great healthy side dish that you can serve with so many other delicious recipes.  Here are some of my favorite ways to serve it:

• Protein: Such as this Healthy Turkey Meatloaf, Chicken Pizza Bake, or this Healthy Turkey Burger. 
• Salad: Such as this Easy Kale Salad, Israeli Couscous Salad, Kale and Brussel Sprout Salad, or this Crispy Chickpea Kale Caesar Salad. 
• Meatless Additions: Like these Baked Eggplant Meatballs or this Healthy Baked Falafel. 

What can you do with leftover mashed butternut squash?

You can easily store cooked, mashed squash and use it in soups or chili. It’s also a great prepared side dish that goes with any meal! See below for storing and reheating instructions.

Make ahead and storage

Prepping & Storing Squash: Prep, roast, and mash the squash. Let it cool, then store it in an airtight container in the fridge for up to 3 days.

Reheating:

• Oven: Place the squash in an oven-safe dish and cover and heat it for 20-25 minutes in the oven at 350°F (175°C), 
• Stovetop: Warm over low-medium heat in a pot on the stove; adjust the texture with milk or broth as needed.
• Microwave: Heat in a covered dish at 1-minute intervals, stirring until warm.

Can you freeze mashed butternut squash?

Yes, you can and it actually freezes pretty well. Here is how to freeze and reheat it:

• Freezing: Cool the mashed squash to room temperature, then transfer it to freezer-safe bags or containers, leaving space for expansion. Label with the date and freeze for up to 6 months for the best quality.
• Reheating: Thaw in the refrigerator overnight, then reheat on the stovetop or microwave, adding liquid (like water, broth, or milk) if too thick. Adjust seasoning after reheating as flavors might mellow from being frozen. 

Pro tip! Refresh dry squash with butter, oil, or liquid. Adjust seasoning post-reheat and ensure dairy additions are heated safely.

This is a delicious side dish that is great anytime especially if you are on a low-calorie diet, since butternut squash is a great, healthier alternative to potatoes.
