Add quartered yellow onion (1 medium), carrot (1 cut into 4 pieces) and celery (1 cut into 4 pieces) to a food processor.
Pulse using 1 second intervals until finely chopped (see photo above).
Add olive oil (2 tablespoons) to a large saucepan along with ground chicken (1 Lb).
Cook over medium heat until browned, breaking up with the back of a wooden spoon as you cook.
Set browned chicken aside on a paper towel lined plate, and carefully wipe the saucepan with a paper towel.
Add pancetta (4 Oz) to your saucepan and cook until crispy, about 6-8 minutes.
Add finely chopped veggies to saucepan with the pancetta, and cook until softened, about 8 minutes.
Add dry white wine (1 cup) to your saucepan.
Use your wooden spoon to scrape up any brown bits that have accumulated on the bottom of the saucepan while cooking.
Stir until wine has evaporated, and the pan is almost dry — should take about 10 minutes.
Add tomato paste (1/3 cup) to the saucepan, and stir around until the tomato paste begins to brown — about 5 minutes.
Add ground chicken back to the saucepan, along with the chicken broth (2 cups), heavy cream (1/2 cup), salt (1/2 teaspoon) and bay leaf (1).
Reduce the heat to a GENTLE simmer. You want to cook the bolognese low and slow — it should release gentle bubbles. Cook this way for about 1 ½ hours. You’ll know it’s done when it has the texture of a sloppy joe mixture. At this point the meat should be tender and a lot of the liquid should have evaporated.**
Remove the bay leaf.
Meanwhile, cook your noodles*** per the package instructions.
Serve bolognese over your noodles with freshly grated parmesan, chopped basil, and enjoy!
