Stuffed Acorn Squash with Creamed Spinach
Ingredients
- 2 medium acorn squash halved lengthwise and seeds removed
- 3 tablespoons olive oil divided
- 2 tablespoons maple syrup or brown sugar
- 1 medium onion finely diced
- 3 cloves garlic minced
- 16 ounces fresh spinach or 10 ounces frozen spinach, thawed and squeezed dry
- 4 ounces cream cheese softened
- ¼ cup heavy cream
- ½ cup grated Parmesan cheese divided
- ¼ teaspoon freshly grated nutmeg
- ¼ cup panko breadcrumbs optional, for topping
- Salt and freshly ground black pepper to taste
- Pinch of red pepper flakes optional
Instructions
- Prepare the squash: Preheat your oven to 400°F (200°C). Brush the cut sides of the acorn squash with 1 tablespoon olive oil and season with salt and pepper. Drizzle each half with maple syrup or sprinkle with brown sugar.
- Roast the squash: Place the squash halves cut-side down on a baking sheet. Roast for 30-35 minutes, until the flesh is tender when pierced with a fork but still holds its shape. Flip them over during the last 5 minutes of cooking.
- Prepare the filling base: While the squash roasts, heat the remaining 2 tablespoons of olive oil in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes until softened and translucent.
- Add aromatics: Stir in the minced garlic and cook for another 30 seconds until fragrant, being careful not to let it brown or burn.
- Wilt the spinach: If using fresh spinach, add it to the skillet in batches, stirring until each batch wilts before adding more. If using frozen spinach, add it to the skillet and stir to combine with the onion mixture.
- Create the creamy texture: Reduce heat to medium-low and add the cream cheese, stirring until it melts completely. Pour in the heavy cream and cook for 2-3 minutes until the mixture thickens slightly.
- Finish the filling: Stir in ¼ cup of Parmesan cheese and the nutmeg. Season with salt, pepper, and red pepper flakes if using. The filling should be creamy but not runny.
- Stuff the squash: Spoon the creamed spinach mixture generously into each roasted squash half. Top with the remaining Parmesan cheese and panko breadcrumbs if using.
- Brown the tops: Return the stuffed squash to the oven for 10-15 minutes, until the tops are golden brown and slightly crispy. For extra browning, broil for the last 1-2 minutes, watching carefully to prevent burning.
- Serve: Allow the stuffed squash to cool slightly before serving. Each person can enjoy their own squash half as a main course, or halve them again for smaller side portions.
Notes
- For meal prep, roast the squash and prepare the filling up to 2 days ahead, then assemble and bake just before serving.
- The squash is easier to cut if you microwave it for 2-3 minutes first to soften the skin.
- For a more substantial meal, add cooked quinoa, wild rice, or browned sausage to the spinach filling.
- Acorn squash skins are edible when roasted, so you can eat the entire dish if desired.
- For best results, choose squash that feel heavy for their size with dull, not glossy, skin.

Common Mistakes to Avoid
- Undercooking the squash: Make sure the squash is fork-tender before stuffing, or it will be difficult to eat.
- Watery spinach filling: Be sure to thoroughly drain frozen spinach or cook fresh spinach long enough to evaporate excess moisture.
- Overseasoning: The natural sweetness of the squash is a key flavor component; don’t overwhelm it with too much salt or spice.
- Cutting squash unevenly: Try to halve the squash symmetrically so they sit flat and cook evenly.
- Overfilling: Leave a little room at the top of each squash half to prevent spillover during the final baking.
Alternatives & Substitutions
- Dairy-free version: Substitute coconut cream for heavy cream, and nutritional yeast for Parmesan cheese.

- Greens variations: Swiss chard or kale can replace spinach (cook slightly longer to tenderize).

- Flavor twists: Add crumbled blue cheese, dried cranberries, or toasted pine nuts to the filling for different flavor profiles.
- Spice alternatives: Cinnamon or allspice can replace nutmeg for a different warming note.
FAQs
Can I make this recipe ahead of time?
Absolutely! Roast the squash and prepare the filling up to 2 days in advance. Store them separately in the refrigerator, then assemble and bake before serving. You may need to add 5-10 minutes to the final baking time if the components are cold.
Is the acorn squash skin edible?
Yes, when acorn squash is properly roasted, the skin becomes tender enough to eat. However, some people prefer to just eat the flesh and filling. It’s entirely a matter of personal preference.
How do I know when the squash is done roasting?
A fork should easily pierce the flesh with little resistance. The squash should be tender but still hold its shape well enough to act as a vessel for the filling.
What can I serve with this stuffed squash?
For a complete meal, pair it with a simple green salad dressed with vinaigrette. If serving as a side dish, it complements roasted chicken, turkey, or pork beautifully.
Can I freeze leftover stuffed squash?
Yes, though the texture may change slightly upon reheating. Wrap individual portions well and freeze for up to 2 months. Reheat covered in a 350°F oven until warmed through.
