In large saucepan, cook bacon until crisp. Dry with paper towel, then crumble.
Remove almost all the bacon fat from the pan and add the onion.
Once the onion is sweated, add the chicken broth, squash, pears and celery.
Bring to a boil, reduce heat, cover and simmer for 30 minutes.
Let cool a little, then blend the mixture with immersion blender.
Put back in the pan and add the herbs de Provence and the bacon.
Continue cooking over low heat for about 10 minutes.
Add the cream, salt and pepper.
