Step‑by‑Step Instructions for Stuffed Baked Acorn Squash
Step 1: Preheat and Prepare the Squash
Preheat your oven to 400°F (200°C). While the oven warms up, cut the acorn squashes in half and scoop out the seeds. Brush the cut sides generously with olive oil, then season them with salt and freshly ground black pepper. Place each squash half cut-side down on a parchment-lined baking sheet and roast for 30–35 minutes until they are tender and beginning to caramelize.
Step 2: Sauté the Aromatics
In a skillet, heat 1 tablespoon of olive oil over medium heat. Once hot, add the finely chopped yellow onion and sauté for about 3–4 minutes, stirring frequently, until the onion becomes translucent and fragrant. Then, toss in the minced garlic and cook for an additional minute, allowing the aroma to fill your kitchen.
Step 3: Add the Veggies
Next, stir in the diced red and yellow bell peppers into the skillet. Cook these colorful additions for 3–4 minutes, stirring occasionally, until they start to soften. Then, add in the chopped sun-dried tomatoes, cooked quinoa, dried thyme, and oregano, along with salt and pepper to taste. Let the mixture cook for another 5 minutes, allowing all the flavors to meld beautifully, before removing it from the heat.
Step 4: Fill the Squash
Carefully flip the roasted acorn squash halves over so the cut sides are facing up. Spoon the quinoa and vegetable mixture into each half, pressing it down gently to pack the filling tightly. The colorful stuffing should be heaping, creating a delightful presentation for your Stuffed Baked Acorn Squash.
Step 5: Add Cheese and Bake Again
Sprinkle the stuffed squash with shredded mozzarella or Gruyère cheese, followed by the grated Parmesan cheese for an extra savory layer. Return the stuffed acorn squashes to the oven and bake for an additional 10–15 minutes, until the cheese is melted and bubbling, and the tops are golden brown.
Step 6: Garnish and Serve
Once baked, remove the Stuffed Baked Acorn Squash from the oven and let them cool slightly. Garnish each half with freshly chopped parsley for a pop of color and freshness. Serve warm, allowing everyone to dig into this hearty and inviting dish that is sure to become a family favorite!

Stuffed Baked Acorn Squash Recipe FAQs
How do I choose the perfect acorn squash?
Absolutely! When selecting acorn squash, look for ones that feel heavy for their size with a vibrant color and no dark spots all over. The skin should be firm and slightly dull. Avoid squashes that have soft spots or blemishes, as these may indicate overripeness.
What is the best way to store leftover Stuffed Baked Acorn Squash?
For sure! Once your stuffed acorn squash has cooled completely, store leftovers in an airtight container in the refrigerator for up to 4 days. To keep them fresh longer, tightly wrap each half with foil or plastic wrap, then place in a freezer-safe bag. That way, you can enjoy them at a later date!
Can I freeze Stuffed Baked Acorn Squash?
Yes, indeed! To freeze, first allow the stuffed acorn squash to cool down completely. Then, wrap each half securely in plastic wrap followed by foil to prevent freezer burn. Place the wrapped squash in a freezer-safe bag for extra protection. They will keep well for up to 2 months. To reheat, thaw overnight in the refrigerator, then warm in a preheated oven at 350°F (175°C) for about 20–25 minutes until heated through.
What if my acorn squash is overcooked?
Very good question! If your acorn squash ends up overcooked, you may find it mushy and less enjoyable. To avoid this, check it during roasting at around 25 minutes, as cooking time can vary with oven types. Ensure it’s tender but still holds its shape. If you do overcook it, consider pureeing the squash into a soup or adding it to baked goods to salvage the dish!
