Spicy Cheesy Chicken Meatballs

Preheat the oven to 350 degrees F (175 degrees C). Grease a baking pan with cooking spray; line with foil.

Whisk eggs and sour cream in a large bowl until fluffy, about 2 minutes. Add Parmesan cheese, Italian seasoning, garlic powder, red pepper flakes, salt, and pepper; stir to combine. Add chicken; mix with your hands until well combined. Mix in crushed crackers until you can form a ball with the mixture. Use your hands to roll into 8 to 10 equal-sized meatballs; place in the prepared pan.

Bake in the preheated oven until no longer pink in the center, about 15 minutes. An instant-read thermometer inserted into the center of each meatball should read at least 165 degrees F (75 degrees C).

Place marinara sauce in a medium saucepan; add meatballs and simmer over low heat until warm, about 10 minutes.
