You may have come across other acorn squash recipes that use the typical sweet ingredients – a little butter, brown sugar, cinnamon and maple syrup, but this version offers a savory, herb flavor that contrasts and pairs beautifully with other holiday side dishes like maple pecan carrot casserole, candied sweet potatoes and good ole’ Southern cornbread dressing!

Why this recipe works

Acorn squash is a winter squash and is readily available during the Fall and Winter months. This recipe focuses on the all-natural delicious flavors of this winter vegetable, accented with a hint of salty Parmesan cheese and a light herb flavor from the seasoned bread crumbs. I guarantee you, this is one of the best savory acorn squash recipes around!

  • Affordable – you can make a large casserole dish for your holiday table without breaking the bank, in fact, it’s as affordable as my Southern eggplant casserole recipe!
  • Healthy side dish – squash is loaded with nutrients and vitamins and is a great source of iron
  • Easy to make in advance – especially when you’re holiday cooking, you need that precious oven space; make this ahead of time and just reheat!
  • Great for serving large groups – turning baked squash into a casserole allows you to serve large groups without having to hollow out individual squash; just combine the cooked squash mixture and top with the herbed seasoned topping, then bake

What you’ll need

First things first, you’ll need a sharp knife. The hardest part of this is cutting the squash in half and a super-sharp chef’s knife really does the trick. Next, you’ll need the following ingredients: (See Recipe Card below and Recipe Notes)

  • Acorn squash – these are the round green squash in your local grocery store that look like a big acorn! Depending upon the size, once you hollow out the center and remove the seeds, you’ll get about ¾ – 1 cup of squash flesh per squash, so keep this in mind if you’re serving a large group
  • Butter – I use unsalted butter, but you can use salted if that’s all you have. You’ll need some for the prepared baking pan and a little melted butter for the bread topping mixture
  • Eggs – large eggs
  • Pecorino cheese – grated; you want a sharp aged cheese. If you can’t find Pecorino, use Parmesan, Asiago or Romano cheese
  • Breadcrumbs– I recommend using Pepperidge Farm Herb Seasoned Stuffing Mix-the infused herbs in the stuffing mix help lift up the savory flavor
  • Onion powder 
  • Minced garlic– I use jarred minced garlic; it’s easy to measure 
  • Milk – 2% or whole milk
  • Ground sage
  • Ground thyme
  • Salt and pepper

How to make it

This classic baked acorn squash recipe comes together from start to finish in about 1 hour, so keep this in mind when you’re planning your holiday menu. This an overview. For exact measurements and ingredients, see the complete recipe in the recipe card below. 

Step 1 How to cut acorn squash

Place the acorn squash on a cutting board and cut about 1/2″ inch off each end to form a flat surface

Place it on a cutting board, cut side down, and (using a sharp knife), slice in half; use a spoon to scoop out the seeds and the stringy flesh

In a 9 x 13 baking dish, add 1/2″ inch of water and place squash halves cut side down

Bake on the middle rack in a 350°F preheated oven, uncovered, for 25-40 minutes (see recipe notes below)

You’ll know when it’s done when you can squeeze it with a long handled pair of tongs and it gives a little

Remove from the oven and allow to cool a little; then, hollow center with a large spoon by removing the inner soft flesh and place it in a large bowl

Use a fork or potato masher to mash the cooked squash; set aside

Meanwhile, prepare a 7 x 11 buttered casserole dish by rubbing a little butter around the bottom and sides

Step 2

  • Add milk, eggs, onion powder, minced garlic, a little salt and pepper, and half of the grated Pecorino cheese to the cooked squash; combine well
  • Spoon the mixture into the prepared casserole dish and smooth the mixture with a spatula; meanwhile, melt butter in microwave or in a small saucepan on medium heat

Bake 350°F, uncovered on the middle oven rack for 25 minutes

Once the topping is golden brown, you can turn the oven to broil for 1-3 minutes to ensure a crisp topping

Remove from oven and allow to rest at room temperature for 5 minutes, then serve

Recipe Tips

An average size acorn squash weighs around 1½ – 2 lbs. This recipe calls for 5-6 pounds of squash, so be sure to weigh them when you’re at the grocery store.

If you don’t have a sharp chef’s knife, you can soften the acorn squash first by either parboiling it in a large stockpot or Dutch oven with really hot water for 5 minutes or, you can place it in the microwave for a few minutes to soften the outer skin. In my experience, a sharp knife is easiest.

You may need to use two large 9 x 13 baking pans to bake the halves – especially if they’re large; I got three acorn halves per 9 x 13 so I had to use two pans

The actual cooking time will be determined by the size of your squash and the heat of your oven; I cooked 5 pounds of acorns (6 halves) in a 350°F oven and it took about 50 minutes

Storage and reheating

If you have leftover baked squash casserole, you can store it in an airtight container in the refrigerator for up to 5 days. For best results when reheating, place the baking dish on a baking sheet (on the middle rack of the oven), in a 200°F oven, covered with aluminum foil, or scoop out individual servings and reheat in the microwave a few minutes.

Notes

Acorn squash
Weigh the squash at the store; you’ll need between 5- 6 pounds of squash, which equates to about 3-4 large squash. Once cooked, you’ll want to have about 6 cups of cooked squash. I used large squash and got one cup of cooked squash from each half.
Pecorino cheese
You can substitute with Parmesan, Romano or Asiago cheese
Breadcrumb Topping
You may have to add a little more melted butter to the dried bread crumb topping; you want it to be moist, but not gummy
Salt
Taste the acorn squash mixture for salt before you put the topping on to make sure it’s salty enough for you. You can always add more, but you can’t take it out.
Yield
I got about 12 half-cup servings from 5 pounds of cooked squash. You may get more or less depending upon how much squash you bake, the size and depth of the baking dish, and the size of the serving spoon.
