What You’ll Need

Mushrooms: Cremini or button mushrooms work perfectly; ensure they are firm and have no dark spots.
Onion: A medium yellow onion adds sweetness to the filling; make sure it’s fresh to avoid bitterness.
Garlic: Fresh garlic cloves elevate the flavor profile; opt for plump cloves for maximum taste.
Vegetable Broth: Using broth instead of water enhances the flavor of the quinoa significantly.
Olive Oil: Extra virgin olive oil is best for cooking the vegetables; it adds richness to the dish.
Spices: Salt, pepper, thyme, and sage bring out the best in these ingredients; fresh herbs can be used too!

Cooking Instructions

Follow these simple steps to prepare this delicious Mushroom and Quinoa Stuffed Acorn Squash:

Step 1: Prepare the Acorn Squash

Preheat your oven to 400°F (200°C). Slice each acorn squash in half lengthwise and scoop out the seeds. Drizzle with olive oil, sprinkle salt, and place them cut-side down on a baking sheet lined with parchment paper.

Step 2: Roast the Squash

Pop those lovely halves into the preheated oven. Roast them for about 25-30 minutes or until they’re tender enough to pierce easily with a fork. Your kitchen will fill with an irresistible aroma!

Step 3: Cook the Quinoa

While the squash roasts away, rinse one cup of quinoa under cold water. In a medium saucepan over medium heat, add quinoa and two cups of vegetable broth. Bring it to a boil then reduce heat to low, cover, and simmer for about 15 minutes until fluffy.

Step 4: Sauté Vegetables

In a large skillet over medium heat, add some olive oil, followed by diced onions and minced garlic. Sauté until translucent. Add chopped mushrooms along with thyme and sage; cook until mushrooms soften.

Step 5: Combine Filling Ingredients

Mix the cooked quinoa into the mushroom-onion mixture until everything is well combined. Adjust seasoning with salt and pepper as needed—don’t forget to taste!

Step 6: Fill & Bake

Remove roasted squash from the oven (careful! They’re hot!). Flip them over so they’re cut side up. Generously spoon in your mushroom-quinoa mixture into each half. Return them to the oven for another 15 minutes so all those flavors meld together beautifully.

Transfer to plates and drizzle with sauce for the perfect finishing touch! Enjoy your culinary masterpiece known as Mushroom and Quinoa Stuffed Acorn Squash!

This delightful dish not only serves as an eye-catching centerpiece but also packs nutritional benefits that will keep you feeling great long after the last bite!
