It’s like nature’s very own edible bowl, just begging to be filled with something incredible. And let me tell you, this Wild Rice & Mushroom Stuffed Acorn Squash is more than incredible—it’s a total showstopper.

Get ready for your kitchen to smell absolutely amazing!

A Squash, A Memory, and My Grandma’s Table
This recipe always takes me right back to my grandma’s kitchen on a crisp October afternoon. I was maybe ten years old, and she handed me a spoon with a mission: scoop out the “guts” of a gnarly-looking squash. I remember making a face, but she just laughed that warm, knowing laugh of hers. “Just you wait, Em,” she said. “We’re making magic.” She wasn’t wrong. As the squash roasted, its earthy, sweet scent mingled with the savory aroma of sautéing onions and mushrooms, creating a perfume that defined comfort for me. Her version had sausage, but over the years, in my own kitchen, I’ve played and tinkered, eventually landing on this plant-based masterpiece that captures that exact same feeling of warmth and abundance. It’s a dish that feels both rustic and elegant, humble and celebratory—just like my grandma’s cooking always was. Every time I pull this golden, stuffed squash out of the oven, I feel like I’m sharing a little bit of her magic with all of you.
Gathering Your Flavor Party: The Ingredients
Here’s your shopping list for this autumnal masterpiece! Don’t be shy with the seasonings—this is where the personality comes to life.
- 2 medium acorn squash, halved and seeds removed – Look for squash that are heavy for their size and have a deep green color with a nice orange patch. That orange spot is a sign of sweetness! No acorn squash? Buttercup or delicata are fantastic substitutes.
- 1 tbsp olive oil – For roasting. This gives the squash a beautiful caramelized edge.
- Salt & pepper to taste – The fundamentals! Season every layer for the best flavor.
For the Savory, Hearty Filling:
- 1 cup wild rice blend – I love a blend for its varied texture and nutty flavor. True wild rice takes longer, so a blend is a great time-saver. Brown rice or even farro would work in a pinch!
- 2¼ cups vegetable broth or water – Chef’s tip: Always use broth! It adds a layer of savory depth that water just can’t provide.
- 1 tbsp olive oil – For sautéing our aromatics to perfection.
- 1 small onion, finely chopped – The sweet, savory base of our filling.
- 2 cloves garlic, minced – Because every great savory dish starts with garlic. Always.
- 8 oz mushrooms (cremini or button), chopped – Cremini (baby bellas) have a deeper, earthier flavor than white buttons, but both are delicious. This is your “meaty” texture!
- 1 stalk celery, diced – Adds a subtle, fresh crunch and a classic aromatic flavor.
- 1 tsp dried thyme – The earthy, slightly floral notes are a perfect match for mushrooms and squash.
- ½ tsp sage – This is the taste of the holidays. It’s woodsy, warm, and absolutely essential.
- Salt & pepper to taste
- Optional: ¼ cup dried cranberries or chopped pecans – Chef’s insight: I highly recommend at least one! Cranberries add a pop of sweet-tartness, and pecans give a buttery, toasty crunch. It’s all about the contrast!
Let’s Get Cooking: Building Your Masterpiece
Don’t let the multiple components fool you—this recipe flows together beautifully. Put on some music, and let’s get into the rhythm of cooking!
- Preheat and Prep: Fire up your oven to a toasty 400°F (200°C). Now, let’s tackle the squash. Carefully slice them in half from stem to end. A sharp chef’s knife and a steady hand are your best friends here. Use a sturdy spoon to scrape out the seeds and stringy bits—save those seeds for roasting later if you’re feeling thrifty! Brush the cut sides and cavities generously with olive oil and don’t be shy with the salt and pepper. Place them cut-side down on a parchment-lined baking sheet. This helps them steam and become incredibly tender. Roast for 30-35 minutes.
- Cook the Rice: While the squash is roasting, let’s get our rice going. In a medium saucepan, combine your wild rice blend and vegetable broth. Bring it to a lively boil, then immediately slap a lid on it, reduce the heat to low, and let it simmer gently. It’ll need about 45 minutes to become tender and pop open. Little chef hack: No need to stir! Just let it do its thing. Once done, fluff it with a fork and let it hang out.
- Sauté the Good Stuff: Heat olive oil in a large skillet over medium heat. Toss in your chopped onion, celery, and a pinch of salt. Sauté for about 5 minutes until they start to soften and get fragrant. Now add the garlic and stir for just 30 seconds until you get that amazing smell. Add your chopped mushrooms! They’ll release water at first—just keep cooking, stirring occasionally, for 8-10 minutes until all that liquid evaporates and the mushrooms get a beautiful golden-brown color. This is where the big flavor develops! Stir in the dried thyme, sage, and another good crack of black pepper.
- Bring It All Together: In a large bowl, combine your fluffy cooked wild rice and the savory mushroom mixture. Taste it! This is your moment. Does it need more salt? More pepper? Adjust now. If you’re using cranberries or pecans, fold them in here.
- Stuff and Finish: Your squash halves should be tender and easily pierced with a fork. Carefully flip them over so they’re like little boats ready for their cargo. Generously mound the wild rice and mushroom filling into each cavity—pile it high! Pop the baking sheet back into the oven for another 10 minutes to let everything heat through and the flavors meld into one glorious combination.
Plating Up the Cozy
Okay, the moment of truth! Pull that gorgeousness out of the oven. I like to transfer each stuffed squash half to a individual plate—it makes for such a stunning presentation. For a final chef-y touch, garnish with a little something fresh. A sprinkle of chopped fresh parsley or thyme adds a burst of color and freshness. If you went the pecan route, a few extra pieces on top look beautiful. This dish is a complete meal all on its own, but if you’re serving it as part of a bigger feast, it pairs beautifully with a simple arugula salad with a bright lemon vinaigrette to cut through the richness. It also makes a wonderful side to a holiday turkey or a cozy roast chicken. However you serve it, serve it with pride!
Make It Your Own: Delicious Twists
This recipe is a fantastic canvas for your creativity. Here are a few of my favorite ways to switch it up:
- Apple & Sage: Add one small, finely diced apple (like a Honeycrisp or Granny Smith) to the skillet when you sauté the onions. The sweet-tartness is incredible with the sage.
- Thanksgiving Leftovers: Got leftover stuffing? Fold a half-cup into the rice mixture for the ultimate holiday flavor bomb.
- Cheesy & Luxurious (Vegetarian): Not strictly vegan? Oh my goodness, sprinkle the top with a handful of sharp white cheddar or gruyere cheese before the final 10 minutes of baking. Let it get all bubbly and golden.
- Protein Power-Up: Add a can of rinsed and drained lentils or some chopped walnuts to the filling for an extra hit of plant-based protein and heartiness.
- Southwest Style: Swap the thyme and sage for cumin and chili powder. Use black beans instead of mushrooms, and add a little corn and lime juice. Top with avocado and cilantro!
Chef Emily’s Notebook Scribbles
This recipe has truly evolved in my kitchen. The first time I made it, I completely overcooked the squash and it collapsed into a delicious but… soupy mess. We still ate it with spoons and loved it! The lesson? Keep an eye on it after 30 minutes. Oven temperatures can vary wildly. I’ve also learned that this filling is magical on its own. Sometimes I’ll make a big batch and eat it as a rice bowl for lunch throughout the week. It’s one of those forgiving, flexible recipes that welcomes your own personal touch. Don’t be afraid to play with what you have in your pantry—that’s where the best cooking happens!
Your Questions, Answered!
Q: Can I make any part of this ahead of time?
A: Absolutely! You can cook the wild rice and sauté the mushroom filling up to 2 days in advance. Keep them separate in airtight containers in the fridge. When you’re ready, roast your squash, combine the filling ingredients to warm them up, stuff, and bake!
Q: My squash is still really hard after 35 minutes. What gives?
A: No worries! Squash sizes and oven temps can be tricky. Just flip them cut-side up, add a splash of water to the pan to create steam, cover the whole pan with foil, and roast for another 10-15 minutes until tender.
Q: Is there a faster rice option?
A: You bet. Pre-cooked or parboiled rice blends (like the ones you find in the freezer section or pouches) are a huge time-saver. Just make sure to season well, as you’re not cooking it in broth.
Q: The filling is a bit dry. How can I fix it?
A: Easy fix! Stir in a tablespoon or two of extra vegetable broth or a drizzle of olive oil into the filling mixture before you stuff the squash. This will make it moist and perfect.
