This is the best kind of comfort food — the kind that cooks itself. Just throw everything in the pot and come back later. Slow Cooker: It’s almost like magic.
Place all of the ingredients in a 4- to 5-quart slow cooker in the following order: carrots, celery, onion, garlic, lentils, bay leaves, thyme, salt, pepper, and broth. Cover with the lid and cook on low for 6 hours. Uncover, stir in the bacon and heat for 30 more minutes. Remove the bay leaves and serve.
