Preheat the oven to 400°F/200°C. Move the oven rack to accommodate your Dutch oven or roasting pan.
Cook the bacon in a medium skillet for a couple minutes until it takes on some color and the pieces separate. Remove to a plate. Reserve the drippings to cook the sausage.
Brown the sausage on all sides and remove to a plate.
Assemble the veggies.
Add about half the veggies to the roasting pan, season as desired, then top with the meats and remaining vegetables. Season the top layer, too.
Tuck the bay leaves and peeled garlic cloves into the mix.
Pour over most of the broth. Cover the roasting pan with a lid or foil.
Place in a hot oven and reduce the heat to 300°F/150°C.
Cook for 1 1/2 to 2 hours. After that time, check the amount of liquid left, adding more if necessary. The veggies should be cooked through, but not falling apart.
Return to the oven for another hour or so. The potatoes and carrots should be easy to cut with a fork by this point.
Thicken the juices if desired to make them more gravy like.
Serve your Irish Coddle with plenty of crusty bread.
