Spaghetti Squash Carbonara

Preheat oven to 400°F (200°C). Line a large baking tray with parchment paper. Set aside.
Trim the ends of the squash, poke holes all over its skin using a fork.
Cut the squash halfway lengthwise, scoop out all the seeds with a spoon and discard the seeds.
Place each half of squash flesh down on the prepared baking tray.
Bake for about 30-45 minutes or until you can easily scrape out spaghetti strands from the vegetable using a fork. The outer flesh may cook faster than the inside. If so, scrape out the cooked spaghetti and keep baking the remaining part that is hard to scrape out until soft enough. Always use oven mittens to do this as the vegetable is quite hot.
Place the cooked spaghetti strands in a large mixing bowl to cool down for 10 minutes while preparing the pasta sauce.

Slice the pancetta roughly into pieces.
Heat olive oil in a non-stick large frying pan or skillet - large enough to fit the spaghetti squash strands as you will add them into this pan later in the recipe.
Cook the pancetta for 3-5 minutes or until crispy, tossing often. Add the chopped garlic. Stir in the cooked, hot spaghetti strands into the skillet. Toss with the crispy pancetta and cook for 1-2 minutes until the spaghetti strands are well combined and flavored. Stop the heat. Cover with a lid.
Meanwhile, microwave the broth for 30-50 seconds, or just until lukewarm. Set aside.
In another bowl, beat the egg yolks, egg, and finely grated Parmesan until well combined.
Remove the lid from the pan (make sure you turn off the heat!) and quickly add the Parmesan egg mixture to the pan. Always make sure the pan is not too hot and you work fast, or it cooks and scrambles the eggs!
Keep stirring to evenly cover the pasta with the sauce. Finally, add a splash of lukewarm stock to loosen the sauce and make it silky - optional.
Bring back to low heat and stir in heavy cream. Cook 1-2 minutes, until just hot, taste the sauce, and add salt or pepper to taste.
Plate up with extra Parmesan on top and chopped fresh herbs of choice.
