How to Make Mushroom Quinoa Stuffed Acorn Squash

Creating this beautiful and delicious dish is easier than you think! Follow these simple steps to assemble your own Acorn Squash Stuffed with Mushrooms and Quinoa.

Step 1: Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup. This high heat is key to getting the squash tender.
Step 2: Carefully cut each acorn squash in half lengthwise. Use a spoon to scoop out the seeds and stringy bits from the center. Brush the cut flesh with about 1 tablespoon of olive oil and sprinkle with half of the kosher salt. Place the squash halves cut-side down on the prepared baking sheet. Roast for approximately 30-35 minutes, or until the flesh is fork-tender. You want it soft but not mushy.
Step 3: While the squash is roasting, prepare the filling. In a large skillet, heat the remaining 1 tablespoon of olive oil over medium-high heat. Add the finely chopped Baby Bella mushrooms and minced shallots. Sauté for about 6-8 minutes, stirring occasionally, until the mushrooms release their moisture and begin to soften and turn golden brown, filling your kitchen with a wonderful aroma.
Step 4: Stir in the minced garlic and cook for just 1 minute more until fragrant – be careful not to burn it! Add the dry quinoa to the skillet and toast it for 1-2 minutes, stirring constantly. This step really brings out the nutty flavor of the quinoa.
Step 5: Pour in the vegetable broth and whole milk. Add the fresh thyme sprigs, the remaining kosher salt, and black pepper. Bring the mixture to a boil, then reduce the heat to low, cover the skillet, and let it simmer gently for 17-20 minutes, or until the quinoa has absorbed all the liquid and is fluffy. Remove the thyme sprigs.
Step 6: Once the quinoa is cooked, stir in about half of the grated Parmesan cheese. This step is crucial for that savory, cheesy goodness in every bite of your Quinoa and Mushroom Stuffed Acorn Squash Recipe.
Step 7: Gently fill each roasted acorn squash half generously with the mushroom and quinoa mixture. Mound it slightly in the center. Sprinkle the remaining Parmesan cheese evenly over the top of each stuffed squash half.
Step 8: Return the stuffed squashes to the oven. Bake for another 10-15 minutes, or until the cheese on top is melted, golden, and bubbly. The aroma at this stage is incredible!
Step 9: Carefully remove the baked acorn squash with mushroom quinoa from the oven. Drizzle each half with the sweet and tangy balsamic glaze and sprinkle generously with the bright pomegranate arils for a beautiful finish and a burst of flavor. Serve immediately and enjoy this fantastic Mushroom and Quinoa Stuffed Winter Squash!

Pro Tips for the Best Mushroom Quinoa Stuffed Acorn Squash

I’ve made this dish more times than I can count, and a few little tricks really elevate it. Here are my top tips for making your Mushroom Quinoa Stuffed Acorn Squash absolutely perfect:

Roast the squash cut-side down: This helps it steam in its own juices, ensuring it becomes perfectly tender and flavorful.
Don’t skip toasting the quinoa: A quick toast in the skillet before adding liquid brings out its nutty depth, making the filling much more complex.
Use fresh herbs: Fresh thyme adds a wonderful aromatic quality that dried herbs just can’t match in this recipe.
Taste and adjust seasoning: Always taste your filling before stuffing the squash. A little more salt or pepper can make a big difference!

What’s the secret to perfect Mushroom Quinoa Stuffed Acorn Squash?

The real magic lies in balancing the earthy flavors of the mushrooms with the nutty quinoa and the sweet squash. Roasting the squash cut-side down first locks in moisture, and toasting the quinoa before cooking adds a wonderful depth. It’s all about building layers of flavor!

Can I make Mushroom Quinoa Stuffed Acorn Squash ahead of time?

Yes, you can definitely prep components ahead! Roast the squash and prepare the quinoa filling up to a day in advance. Store them separately in the refrigerator.

How do I avoid common mistakes with Mushroom Quinoa Stuffed Acorn Squash?

Avoid overcooking the squash, which can make it mushy. Also, be careful not to burn the garlic when sautéing; add it towards the end. Finally, don’t overmix the filling after adding the cheese; gentle stirring preserves the fluffy texture of the quinoa.
