Why you should make this recipe

Hubbard squash can get very large, and if find yourself with one, and you are not feeling particularly confident about handling it, this is a perfect option.

  • Easy – This recipe couldn’t be easier. Just place the squash on a baking sheet and slide it into the oven.
  • Virtually no knife work – The squash is sliced after it is cooked, and the knife glides right through it.
  • Versatile – Once your squash is cooked, you can use it in so many different recipes.

Can you bake Hubbard squash whole?

Roasting Hubbard squash whole is a great option when you don’t feel like wrestling with a rather substantial vegetable. This particular squash clocked in at about 6 pounds and because of its odd shape, cutting it can be a challenge.

By roasting a Hubbard squash whole, we avoid trying to cut a potentially very large vegetable. The other issue is safety – you may not feel comfortable trying to keep it from rolling around on the cutting board while wielding a knife.

This is what the outside will look like when it’s done. The blueish skin will turn darker and it’ll be blistered on the outside, but perfectly cooked inside and ready to use.

After you break it open, don’t throw away the seeds. You can make roasted Hubbard squash seeds, just like you would do with pumpkin.

Cooking whole squash this way gives you soft, tender flesh. If you like the brown edges of roasted Hubbard squash, you’ll have to slice it open before placing it in the oven.

How to cook a whole squash

Here’s a quick summary of how to roast a whole squash. Please see the recipe card at the bottom of this post for the full recipe. 

Paring knife stuck into Hubbard squash with blue towel on the side.

Cooking it whole in the oven is as easy as it gets. Use a sharp paring knife to make 6 or 7 slits on the top and sides of the squash.

I like to do 2 on each side, then 2 or 3 on the top. The reason you have to do this is to allow the steam a place to escape. If you don’t give it a place to get out, it could make its’ own – in the form of an exploded squash inside your oven.

Think of it like a pressure cooker. The inside of the squash builds up steam in the oven as the flesh cooks. Just like a pressure cooker, it needs an escape valve.

By providing it, we avoid any mishaps with it breaking open on its own. That’s why it is necessary to poke a few holes when we bake a Hubbard squash whole.

Just slide it into the oven, then go watch tv or take the dog outside for a bit, and come back to a perfect cooked squash.

You’ll want to roast the Hubbard on a rimmed baking sheet or in a large baking dish, because a bit of liquid will come out. Make sure you have something with a side, even a short one, to catch it so it doesn’t make a mess in the oven.

How to remove seeds and flesh from squash

After you cut it open, or just break it open, because you don’t really need a knife, this is what it will look like.

Hubbard squash are a dusty blueish gray on the outside. They are usually oblong in shape, but can be rounder as well, like an acorn squash. The flesh is deep orange.

  1. My mother use to cook Hubbards whole. I never have, but just got one, so will bake it as you say. It will taste great this winter from my freezer.
    But first, I will use it and other fall delights as decorations!
    Thank you🕊

  2. Many thanks. My squashes aren’t Hubbards. They are the flattened kind, each weighs approx 10 lb., but I am sure they will cook the same. Will report back if there’s no disaster. 🙂

  3. Hi, I have about a 42 lb. blue hubbard squash. I grew it in the garden. Had no idea it would get that large. What can I do with it? It is huge!

    1. 42lbs.?! WOW! That IS huge! I’ve never seen one that big. You’re definitely going to have to break it into pieces to cook it!
