Divide the cheese out by cubing 2/3 of it and grating the rest. Save the grated cheese for the end of cooking time.
In a large bowl add the eggs, ricotta, salt, pepper, dill and thyme. Whisk until you can get it smooth, though some chunks of ricotta is fine.
Spray the slow cooker with non-stick spray. Add the cubed cheese, bacon and ham. Whisk the egg mixture one more time to get it combined again, then pour over the ham, bacon and cheese.
Cover and cook on HIGH for 2.5 hours. If there is any liquid on top of the casserole, blot it with a paper towel. Add remaining cheese and cover for 5-10 minutes more.
