Make sure the stock is hot, I like stirring the pumpkin into the stock and allowing it to dissolve before getting started as this ensures the rice is cooked through with pumpkin from the beginning. Leave it in a sauce pot and make sure the stock is always warm/hot while making risotto.
In a heavy bottom sauce pot add the bacon and let it render until crispy and the fat is release, this should take 5 minutes.
Scoop out the bacon and add butter into the bacon fat, sauté the onions, garlic, thyme until soft, translucent - around 4-5 minutes on low heat.
Add the rice and sauté for 3 minutes on low heat until it has gotten a little pale in color.
Start by adding the wine and allow it to cook until completely evaporated this should take 3-5 minutes of low to medium heat.
Continue by adding one ladle of stock at a time and keeping stirring. Allow the rice to absorb the stock and cook.
Repeat this process for 6 ladles and give the rice taste, you may need to add more stock or it might be enough. This can vary depending on the brand of the rice.
Once the risotto is cooked through add the parmesan cheese, butter, season with salt and pepper as needed.
Cover, take off the heat and let it sit for 3 minutes. Stir well and serve it with crispy bacon, more parmesan cheese, chopped parsley, salt and pepper.
