Ingredients You’ll Need

Each element in Rosa Jackson’s Mini Pumpkins Stuffed with Onion, Mushrooms, and Chard brings something unique—whether it’s sweetness, depth, color, or creamy richness—so don’t skip a thing!
- Mini pumpkins: Look for sugar pumpkins or small acorn squash; their size makes them perfect for individual servings and they roast up beautifully sweet.

- Onion: When sautéed, onion brings a subtle sweetness and deep flavor base to the filling.
- Garlic: Just two cloves is enough to infuse the filling with irresistible aroma and gentle bite.
- Mushrooms: Cremini or button mushrooms add earthy flavor and a lovely, meaty texture to the stuffing.
- Swiss chard: This leafy green wilts down and melds seamlessly with the mushrooms, giving color and a touch of bitterness that balances the dish.
- Salt and black pepper: Essential for seasoning every layer and drawing out the natural flavors.
- Nutmeg: Just a pinch gives a subtle warmth that makes the filling taste like fall.
- Heavy cream or crème fraîche: Adds creaminess and moisture, binding the filling together luxuriously.

How to Make Rosa Jackson’s Mini Pumpkins Stuffed with Onion, Mushrooms, and Chard
Step 1: Prep and Roast the Mini Pumpkins
Start by preheating your oven to 375°F (190°C) so it’s ready for roasting. With a sharp knife, slice the tops off each mini pumpkin and carefully scoop out the seeds and stringy flesh. Don’t toss those beautiful pumpkin lids—they make adorable tops for serving! Brush the inside of each pumpkin with a bit of olive oil and a pinch of salt, then place them cut-side down on a baking sheet. Roast for 20 to 25 minutes, just until they’re fork-tender but still holding their shape. This step brings out their natural sweetness and ensures they’re ready to cradle that delicious filling.
Step 2: Sauté the Aromatics
While the pumpkins are roasting, set a large skillet over medium heat and pour in the remaining olive oil. Add the chopped onion and let it cook gently for about 6 to 8 minutes, stirring occasionally, until it turns soft and golden. The slow sautéing coaxes out the onion’s sweetness, creating a rich base for the rest of the filling. Next, add the minced garlic and cook for about a minute, just until fragrant—this is the moment when your kitchen starts to smell amazing.
Step 3: Cook the Mushrooms and Chard
Toss in the finely chopped mushrooms and let them cook down for another 5 minutes. As they sizzle, they’ll release their moisture and start to brown, adding a savory depth to the mix. Pile in the chopped chard leaves (don’t worry, they’ll wilt down dramatically), and cook everything together for about 3 minutes. The chard brings a vibrant green hue and a slight earthiness that pairs beautifully with the mushrooms.
Step 4: Season and Enrich the Filling
Now, season the mixture with salt, black pepper, and that enchanting pinch of nutmeg. Stir well so every bite is balanced and flavorful. Pour in the heavy cream or crème fraîche, then sprinkle in the grated Gruyère or Parmesan. Mix until the cheese melts and the filling is creamy and cohesive. Remove the skillet from heat—your filling for Rosa Jackson’s Mini Pumpkins Stuffed with Onion, Mushrooms, and Chard is ready!
Step 5: Fill and Bake
Carefully turn the roasted pumpkins upright and spoon the fragrant mushroom and chard filling into each one, packing it in generously. Place the stuffed pumpkins back in the oven (don’t forget their little lids if you want to use them!) and bake for another 10 to 15 minutes. The tops should turn golden and the filling will be bubbling away, promising all sorts of cozy flavors inside.
How to Serve Rosa Jackson’s Mini Pumpkins Stuffed with Onion, Mushrooms, and Chard

Garnishes
A final flourish of fresh thyme is the perfect finishing touch for Rosa Jackson’s Mini Pumpkins Stuffed with Onion, Mushrooms, and Chard. The tiny green leaves add a pop of color and a gentle herbal aroma that contrasts the warm, creamy filling. If you want to get extra fancy, a sprinkle of extra grated cheese or a drizzle of good olive oil will make each pumpkin look like it came straight from a cozy French bistro.
Side Dishes
These mini pumpkins make a statement all on their own, but they’re even better when paired with simple sides. Try serving them with a crisp autumn salad—think arugula, toasted walnuts, and apples—or alongside a light soup like roasted tomato or butternut squash. Crusty bread is always a welcome addition to soak up any cheesy, creamy filling that might escape.
Creative Ways to Present
For a festive touch, serve each pumpkin on individual plates with their tops propped up at an angle, almost like a little edible gift. Arrange them on a bed of sautéed greens or grains for a heartier meal, or line them up on a platter as an eye-catching vegetarian main at your fall gathering. If you’re looking for a party appetizer, use even smaller pumpkins or gourds for adorable, two-bite versions.
