Prepare The Acorn Squash For Baking
Before beginning, remember to preheat your oven to 400°F. Okay- here we go: Start with a 1½ to 2 pound acorn squash. This is considered a medium sized squash, since they can get as large as 5 pounds!
Carefully slice the squash in half through the middle (NOT stem to bottom!) then scoop out and discard the seeds and pulp from each half.
Place the squash, cut side down, and slice each half into 1″ wide slices, creating a half-moon-shaped slice. Place all the squash slices into a large mixing bowl and set aside.
This is what the “half-moon” squash slices will look like after they have been cut.
Seasoning The Acorn Squash
Now it’s time to make the seasoning sauce for the squash. Melt butter in a small saucepan. When melted, add garlic powder, oregano, thyme, salt and pepper, and stir to combine.
Pour the sauce over the acorn squash slices, and toss gently, until the squash is covered on all sides with the buttery spice mixture.
Bake The Acorn Squash
Lay the seasoned acorn squash slices in a single layer on a large baking sheet. Sprinkle each slice on top with a little grated Parmesan cheese (either fresh grated or the kind you get in a green shaker can).
Bake the acorn squash slices at 400°F. for 20 minutes, or until the squash is tender. You can test the squash for doneness by inserting a knife into the middle of a slice.
The knife should glide in smoothly, indicating the squash is tender. Remove the pan from the oven, and serve the roasted Parmesan acorn squash while hot.
Serve The Roasted Parmesan Acorn Squash
To serve, arrange the roasted Parmesan acorn squash slices on a serving platter or onto individual plates. Garnish with fresh parsley, if desired.
Serve immediately and enjoy this savory vegetable side dish. A butter knife can easily be used to separate (cut away) the tender squash from the peel.
I hope you have the opportunity to try this easy to prepare side dish and trust you and those you love will enjoy it as much as we do.
