• Chef’s knife: For halving the acorn squash and chopping vegetables
• Cutting board: Provides a stable surface for safe and precise cutting
• Sturdy spoon: Scoops out the seeds and stringy bits from the squash
• Baking sheet: Holds the squash halves as they roast in the oven
• Parchment paper: Lines the baking sheet for easy cleanup and prevents sticking
• Medium saucepan: Cooks the quinoa to fluffy perfection
• Large skillet: Sautés the veggie and mushroom stuffing mix
• Mixing bowls: Combine and toss filling ingredients before stuffing
• Measuring cups and spoons: Accurately portion quinoa, broth, spices, and more

• Oven mitts: Protect hands when handling hot pans and baking sheets

I find that these basics carry me through most stuffed squash recipes and they are handy for nearly all my favorite vegan dishes as well.

Instructions

I guide you through each step to create my favorite vegan stuffed acorn squash. Follow these steps to impress even the most dedicated omnivores with a colorful, healthy, plant-based centerpiece.

Prep the Acorn Squash

1. Preheat your oven to 400°F.
2. Wash the acorn squash and cut each in half lengthwise with a sharp chef’s knife.
3. Scoop out seeds and strings using a sturdy spoon. Discard or reserve the seeds to roast later.
4. Lightly brush the cut sides with olive oil and sprinkle with sea salt and black pepper.
5. Place the squash halves cut side down on a parchment-lined baking sheet.
6. Roast for 30 to 35 minutes, until the flesh is fork-tender and golden along the edges.

Prepare the Filling

1. While the squash roasts, rinse 1 cup of quinoa under cold water.
2. Bring 2 cups of water to a boil in a medium saucepan, add the rinsed quinoa, reduce heat, cover, and simmer for 15 minutes until all water is absorbed. Fluff with a fork and let it cool slightly.
3. Heat 2 tablespoons olive oil in a large skillet over medium heat.
4. Add diced onion and sauté for 2 minutes until translucent.
5. Stir in minced garlic, diced celery, diced carrot, and red bell pepper. Sauté for 4 to 5 minutes, stirring often, until the veggies begin to soften.
6. Add chopped cremini mushrooms and cook for another 4 minutes, allowing moisture to evaporate.
7. Stir in the cooked quinoa, dried cranberries, and toasted walnuts or pecans. Season generously with sea salt and black pepper.
8. Taste and adjust seasoning as needed.

Stuff and Bake the Squash

1. Remove the roasted acorn squash from the oven and turn halves cut side up.
2. Generously spoon the warm quinoa filling into each squash cavity, mounding if needed.
3. Return the stuffed squash to the oven and bake for 10 to 12 minutes at 400°F, just until piping hot and the edges begin to crisp.
4. Remove from oven and let cool for a few minutes.
5. Garnish with fresh parsley, pomegranate seeds, a drizzle of tahini, nutritional yeast, or toasted pumpkin seeds to finish—choose your favorites for extra flavor and crunch.

Make-Ahead Tips

I love prepping parts of this vegan stuffed acorn squash ahead of time to keep things stress-free on busy days or when I have guests. Here’s how I set myself up for easy assembly later:

• I roast the acorn squash up to two days in advance. After roasting, I let the halves cool completely. Then I store them in an airtight container in the fridge.
• I prepare the filling a day or two ahead as well. I cook the quinoa and sauté the vegetables according to the recipe. Once cooled, I mix in the cranberries and nuts. I store the filling in a sealed container in the fridge.
• When I am ready to serve, I preheat the oven to 375°F. I bring the filling and squash halves to room temperature for about 20 minutes, then I stuff the squash and bake until heated through, about 20 to 25 minutes.
• If I want to freeze the dish, I cool both the roasted squash and prepared filling separately. I store them in freezer-safe containers. When I am ready to use, I thaw overnight in the fridge, stuff the squash, then bake as usual.
• For weekday lunches, I portion the stuffed squash in individual containers so I can quickly reheat a serving in the microwave or oven.

These flexible steps let me enjoy delicious and healthy vegan stuffed acorn squash any night of the week with minimal effort.

Serving Suggestions

I love showcasing vegan stuffed acorn squash at the center of the table. Its vibrant colors and savory aroma always get guests excited. For a well-balanced meal, I often serve it with a crisp green salad tossed in a lemon-tahini dressing. The acidity brightens up the rich, earthy squash and complements the nut-studded filling.

For casual dinners, I pair the squash with roasted Brussels sprouts or steamed green beans. These sides add extra crunch and a fresh, green flavor that makes the whole plate feel lighter. I sometimes drizzle the squash with additional tahini or a touch of balsamic glaze for a silky finish.

If I have leftover stuffing, I spoon it beside the squash or tuck it into lettuce cups for a fun appetizer. For hearty appetites, I include a scoop of vegan mashed potatoes or a simple quinoa pilaf. When entertaining, I sprinkle fresh pomegranate seeds and parsley on top for a pop of color and festive look.

Here are some of my favorite serving ideas:

• Serve as a main course with a side of lemony kale salad
• Pair with roasted winter vegetables for a seasonal vegan feast
• Add a scoop of the filling to grain bowls for lunch the next day
• Top with toasted pumpkin seeds and a dollop of vegan yogurt for extra creaminess

With these pairings and toppings, vegan stuffed acorn squash shines as both a weeknight dinner and an impressive holiday centerpiece.

Storing and Reheating
