In a medium, heavy saucepan, melt butter over medium heat. Add the onions, garlic, thyme, seasoning, pumpkin pie spice and crushed red pepper flakes, cooking for 3 minutes. Add the rice and stir to coat. Cook for another 2 minutes.
Add in the pumpkin, coconut milk and water. Cover and bring to a simmer.
Simmer for 25-30 minutes or until the liquid is absorbed and pumpkin is cooked. Fluff the rice with a fork and serve.
Notes
If you have trouble finding pumpkin, just use butternut squash.
You can replace fresh thyme with dried thyme, but just use ⅓rd of the amount as it is more potent.
Instead of using water, you can substitute with chicken/vegetable stock.
If you like more heat add crushed red pepper flakes in ¼ teaspoon increments. You can even try habanero peppers.
You know the dish is done when the pumpkin is fork tender and the liquid is absorbed.
