A creamy sage and thyme pumpkin soup baked right inside two mini pumpkins under a puffed, golden puff pastry lid. The soup goes in lukewarm so the pastry puffs before anything bubbles over, and you break through the crust with a spoon at the table!
Preheat the oven to 400°F. Line a rimmed baking sheet with parchment paper. Cut the tops from the pumpkins and scoop out all the seeds and stringy pulp. Do not roast the pumpkins beforehand.
Melt the butter in a saucepan over medium heat. Add the onion and cook for 4-5 minutes, until softened and beginning to brown. Add the garlic and cook for 30 seconds longer.
Stir in the pumpkin puree, vegetable broth, cream, maple syrup, sage, thyme, salt, pepper, nutmeg, and cayenne. Bring to a gentle simmer and cook for 5 minutes, stirring occasionally. The soup should be creamy and moderately thick, not watery.
Remove the soup from the heat and let it cool for approximately 15 minutes. It should be lukewarm rather than steaming hot.
Cut two circles of cold puff pastry approximately 1 inch wider than the pumpkin openings. I like to place a bowl upside down on the pastry, then gently cut around it with a paring knife.
Place the hollow pumpkins on the prepared baking sheet. Spoon the soup into them, filling each only halfway to two-thirds full. Leave at least 1 inch between the soup and the top rim.
Drape a pastry circle over each pumpkin, then fold the edges upward and around the rim, rustically overlapping and pleating the pastry as you go rather than pressing it flat. Do not pull the pastry tightly because it needs room to puff. Cut a small slit or "X" in the center to release steam.
Brush the pastry lightly with cream or milk. Bake for 20 minutes, or until the pastry is fully puffed and turning golden brown.
Let the pumpkins rest for 5 minutes. To eat, break through the puff pastry with a spoon. Enjoy!

Notes
Use raw pumpkins. Pre-roasting creates the greatest risk of collapse.
Use lukewarm soup. Hot soup can bubble before the pastry sets.
Leave plenty of headspace. Two-thirds full is enough.
Keep the pastry cold and fairly thick. Warm or overstretched pastry can sag.
Cut a steam vent. This reduces condensation and pressure beneath the lid.
This is best served right away, while the pastry is still puffed and the soup is hot. If you have leftovers, scoop the soup and pumpkin flesh out of the shell and store it in an airtight container in the fridge for up to 3 days. The pastry lid won't stay crisp once it sits, so store it separately if you want to save it, or just expect it to soften. Reheat the soup on the stove or in the microwave, and warm the pastry separately in the oven or air fryer at 350°F for a few minutes if you want to bring back some crunch.If vegan or dairy-free, simply use olive oil and coconut milk in the soup.
