Thanksgiving Side Dish Idea | Baked Butternut Squash Potatoes

Are you looking for a new side to serve for the holidays? It’s no secret that Thanksgiving is my favorite holiday of them all and every year I try a new side to go along with my turkey and cornbread dressing. Recently, I was looking around at my favorite local grocery store, and either the butternut squash was eyeing me or maybe it was the other way around.  Either way, the butternut squash got me thinking about Thanksgiving and what I am going to serve this year. I was inspired, so I grabbed a couple of those squash and put them in my basket to see if inspiration would hit.

Easy side dishes for Thanksgiving

As I walked around the produce section I started to consider so many options, maybe a squash, eggplant, and rutabaga ratatouille. Naw. How about making a sweet potato and caramelized onion cheesy gratin? Nope! Then as my eyes fell upon a big sparkling (do potatoes sparkle?) pile of Yukon gold potatoes the skies opened up and a voice spoke to me, “Make baked butternut squash potatoes…” And there you go! Don’t you just love it when inspiration comes in the form of voices in your head telling you what recipes to make? Me too!

Thanksgiving Side Dish Idea | Baked Butternut Squash Potatoes

Okay, maybe it didn’t’ happen exactly like that (or maybe it did), regardless it’s a great idea that bears repeating and replicating so in the spirit of Thanksgiving I am going to show you how I put this yummy recipe altogether. There are a few things about this mashed potato recipe that are a little different. The first thing, this recipe uses eggs, two whole eggs, and two egg white to exact. Why add eggs? Because eggs help these potatoes literally rise to the occasion and become the best-baked potatoes ever! I also added two cups of really good cheese to this recipe as well. 

And the cheeses in question are two of my favorites! I used a cup each of freshly grated smoked Gruyère and Parmigiano-Reggiano, I mean what can possibly go wrong with this savory dynamic cheese duo? Add to the mix unsalted sweet cream butter, heavy whipping cream, sour cream, freshly cracked black peppercorns, and flaky sea salt and you got a side dish that just might steal all the shine from your Thanksgiving meal. The potatoes are boiled, then roughly smashed so they still retain some of the chunkiness of the potatoes. In my opinion, the texture of not quite totally smooth potatoes is where it’s at and then some. Something about potatoes that manage to be creamy, smooth, and a little bit lumpy makes my taste buds go weak in the knees. After the potatoes are finished boiling and the butternut squash is perfectly steamed, mix them together roughly.

 

Next, it’s time to add some fat in the form of cheeses, heavy whipping cream, sour cream, and a stick of melted butter mix thoroughly. In a small bowl add two whole eggs and two egg whites and use whisk them together. 

Then little by little and the eggs to the potato mixture, next add the beautifully sautéed onions and mix until they are fully incorporated into the potato mixture. If you haven’t noticed by now this is one decadent potato side dish and it doesn’t shy away from bringing the flavor.

Ingredients:

  • 5 cups Yukon gold potatoes
  • 3 1/2 cups butternut squash cut into 1″ cubes
  • 1 cup gruyère freshly grated
  • 1 cup Parmigiano-Reggiano freshly grated
  • 1 cup heavy whipping cream
  • 1/4 cup sour cream

holiday side dishes

 Directions:

  1. Preheat the oven to 350 degrees.
  2. Wash and cut all of the bad spots from the potatoes and cut them into quarters, place them into a stockpot, and fill with water until just covering the potatoes.
  3. Add two tablespoons of kosher salt and set over high heat for twenty to twenty-five minutes or until the potatoes are soft and can be pierced with a fork. Drain off the water and place the potatoes into a large mixing bowl.
  4. Peel the butternut squash and cut into one-inch cubes. Place the squash into a steamer pot with cups of water over med-high heat and steam for four to five minutes or until you can pierce the squash with the tines of a fork. Add the squash to the potatoes.
  5. Add the cheeses, heavy whipping cream, sour cream, and melted to the potato and squash, using a wand mixer mash together until the ingredients are well-combined.
  6. Next, add the two whole eggs and two egg whites and mix thoroughly. Add the smoked flaky sea salt and freshly cracked black peppercorns.
  7. Spoon the mixture into the casserole dish and bake on the center rack for an hour, the top should be golden brown.
  8. Remove from the oven and serve.

Potato recipe for the holidays

So, the only question is, what else are you making for your Thanksgiving dinner? We got a rock-solid potato recipe for you already. But just in case you need help flushing out the rest of your Thanksgiving dinner come back and visit us and I am sure a brotha’ can help you out. 

How long does it take for butternut squash to soften in the oven?

When you are pre-cooking butternut squash to get it nice and tender it takes 30-40 minutes in the oven. Now depending on the size the cook time can vary. Of course, larger squash will take longer than a smaller sized squash. 

What flavors go well with butternut squash?

Sweet or savory works with butternut squash. It is very versatile in flavor. Pairing the squash with potatoes and spices worked out perfectly for this savory side dish. You can pour gravy over or eat it plain. Either way the crunchy topped potatoes are delightful. 

What are the best potatoes for mashed potatoes? 

Yukon Gold, Russets, or even red potatoes make some of the best potatoes. Their starch holds up well when cooked and in this case baked. It creates that ultra creamy texture that you know and love in a good mashed potato recipe. 

Do I need to refrigerate this side dish? 

Yes once your potatoes are done and you have leftovers simply store in an airtight container in the fridge. The potatoes will last a few days. Then just warm up in the microwave for a quick reheat. Or you can warm it up in the oven but you will want to cover with aluminum foil to prevent the potatoes from drying out.
