Preheat the oven to 375 degrees.
Take a baking dish and grease it with nonstick oil.
Add the crushed crackers to a large bowl, add garlic paste, salt, pepper, and mix it well.
Whisk the eggs in another bowl.
Now dip the chicken in the egg and then in the cracker. Coat it perfectly and keep it on the side. Repeat the process for all the chicken breasts.
Now put the chicken on the baking dish and add the small pieces of butter to it.
Bake on the middle rack for at least 40-45 minutes.
