Preheat oven to 375°F (190°C).
In a large skillet, brown the ground beef with onion and garlic over medium heat. Drain any excess fat.
Stir in BBQ sauce, salt, and pepper. Simmer for 5 minutes and remove from heat.
In a 9x13-inch baking dish, spread a small amount of the meat mixture to coat the bottom.
Layer 4 lasagna noodles, half the ricotta, half the meat mixture, half the cheddar, half the mozzarella, and half the bacon.
Repeat with the remaining ingredients.
Cover with foil and bake for 30 minutes. Remove foil and bake an additional 10-15 minutes until cheese is bubbly and golden.
Let sit for 10 minutes before slicing. Garnish with parsley if desired.
