- 1 1/2 pounds bone-in chicken breasts with skin
- 2 cups chicken stock, or as needed
- 1 tablespoon paprika
- 1 teaspoon salt, or more to taste
- 1/2 teaspoon cayenne pepper
- 12 lasagna noodles
- cooking spray
- 1 tablespoon olive oil, or more as needed
- 2 stalks celery, finely chopped
- 1/2 onion, finely chopped
- 2/3 cup buffalo wing sauce
- 1/2 cup crumbled blue cheese
- 1 (16 ounce) container ricotta cheese
- 1 cup blue cheese dressing
- 1 egg
- 1 (8 ounce) package shredded mozzarella cheese
- Place chicken in a single layer in a large pot and add enough chicken stock to cover; season with paprika, 1 teaspoon salt, and cayenne pepper. Bring stock to a boil, reduce heat to medium, and simmer until chicken is no longer pink in the center, 15 to 20 minutes. Shred chicken.
- Bring a large pot of lightly salted water to a boil. Cook lasagna noodles in the boiling water, stirring occasionally until tender yet firm to the bite, about 8 minutes. Drain. Arrange noodles on a sheet of aluminum foil or parchment paper and spray with cooking spray to prevent sticking.
- Heat olive oil in a skillet over medium heat; cook and stir celery and onion until just starting to soften, about 5 minutes.
- Preheat oven to 350 degrees F (175 degrees C).
- Combine onion mixture and shredded chicken in a bowl; add about 1/3 the buffalo wing sauce and blue cheese and mix well.
- Mix ricotta cheese, blue cheese dressing, and remaining buffalo wing sauce in a separate bowl; season with salt and cayenne pepper to taste. Stir egg into mixture.
- Spread a layer of ricotta mixture in the bottom of a 9×13-inch baking dish; top with a layer of 3 noodles. Spread 1/4 of the remaining ricotta mixture over noodle layer; top with 1/3 the chicken mixture, and 1/4 the mozzarella cheese. Layer 3 lasagna noodles over cheese layer and repeat layering 2 times more ending with a layer of ricotta mixture and mozzarella cheese.
- Bake in the preheated oven until cooked through and top is lightly browned, about 45 minutes. Cool lasagna at least 20 minutes before cutting.
