Step‑by‑Step Instructions for Stuffed Baked Acorn Squash
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven warms, carefully slice the acorn squashes in half and scoop out the seeds. Brush each half generously with olive oil and sprinkle with salt and freshly ground black pepper. Place the cut side down on a parchment-lined baking sheet and roast in the oven for 30–35 minutes, or until the squash is tender and easily pierced with a fork.
Step 2: Sauté Aromatics
While the squash is roasting, heat 1 tablespoon of olive oil in a skillet over medium heat. Add the finely chopped onion and sauté for 3–4 minutes until it becomes translucent and fragrant. Next, introduce the minced garlic and cook for an additional 1 minute, stirring frequently to prevent burning. This will create a lovely base for your Stuffed Baked Acorn Squash filling.
Step 3: Cook the Vegetables
In the same skillet, add the diced red and yellow bell peppers, cooking for about 4–5 minutes until they start to soften. Stir in the chopped sun-dried tomatoes, cooked quinoa, dried thyme, oregano, and crushed red pepper flakes if you desire a hint of spice. Season with salt and pepper, letting it cook for 5 more minutes—allow the flavors to meld beautifully.
Step 4: Fill the Squash
Once the squash has finished roasting, carefully flip the halves over to expose the tender flesh. Spoon the flavorful quinoa and vegetable mixture into each half, pressing it down gently to pack it in. Make sure each Stuffed Baked Acorn Squash is generously filled, showcasing the vibrant colors of the filling.
Step 5: Cheese and Final Bake
Sprinkle the shredded mozzarella or Gruyère cheese over the stuffed squash halves, followed by a dusting of grated Parmesan cheese. Return them to the oven and bake for an additional 10–15 minutes, or until the cheese is melted, bubbly, and slightly golden. The aroma wafting from the oven will be irresistible!
Step 6: Garnish and Serve
Once the cheese is perfectly melted, remove the stuffed squashes from the oven. Allow them to cool slightly before garnishing with a sprinkle of freshly chopped parsley for a bright finish. Serve these Stuffed Baked Acorn Squash warm, delighting your family and friends with a meal that’s as beautiful as it is delicious.

Expert Tips for Stuffed Baked Acorn Squash

Are there any dietary considerations I should keep in mind?
Very important!

If you find your filling is too dry, don’t worry! You can add a splash of vegetable broth or extra olive oil to the mixture to achieve a moister consistency.
