Line slow cooker with foil leaving enough foil on the ends to form handles and coat with non-stick cooking spray.
In a large non-stick skillet over medium-high heat, melt butter. Add onion and cook until translucent, about 3 minutes. Add asparagus and sauté until onion has browned and asparagus is crisp tender, about 5 minutes. Set aside.
In a large bowl, whisk together milk, eggs, dill, Lemon Extract, Vanilla Extract, salt and cayenne pepper; set aside. In another large bowl, combine cheeses, bread, cooked onions and asparagus, and ham. Pour milk mixture over bread mixture and stir until all bread is coated with the egg mixture. Transfer to the crockpot.
Cover and cook on low until the internal temperature reaches 170 degrees F, about 3 1/2 to 4 hours (no longer, or the strata can become rubbery or burn). Turn off the slow cooker, remove the lid and let sit for 10 minutes. Carefully grab the foil handles to lift the strata out of the slow cooker and place onto a cutting board. Gently peel away foil and then slice, and serve.
