These simple ground chicken meatballs are cooked in a spicy buffalo sauce, making them great as an appetizer or a meal. As written, the recipe is completely gluten-free. Replace ground flaxseed with traditional breadcrumbs if you prefer.
In a large bowl, lightly beat the egg. Add the ground chicken, flaxseed, olive oil, garlic powder, onion powder, and salt. Stir with a large spatula until completely combined.
Roll meat mixture into balls and place on a large plate or platter until you are ready to cook them. I like to use a cookie scoop (for medium size meatballs) or ice cream scoop (for larger meatballs). My meatballs are usually around 1oz in weight/size. Set aside.
Place half of the buffalo sauce in the bottom of a large pot or slow cooker. Do not heat yet. Set aside.
Heat a large skillet with olive oil over medium heat. Lightly brown the meatballs (about 8 at a time), about 1-2 minutes each side. Place each batch of browned meatballs into the large pot or slow cooker until all meatballs are browned. Cover meatballs with rest of the buffalo sauce.
Cover the meatballs and cook4 in slow cooker on low for 6-7 hours or high for 4-5 hours. If using a pot and the stovetop, simmer over medium-low heat until sauce thickens and meatballs are fully cooked, about 35 minutes. Leftovers will stay fresh in the refrigerator, covered, up to 1 week.
Make ahead: prepare meatballs through the browning step, then cover and refrigerate up to 1 day or freeze up to 2 months. Add to slow cooker or large pot cold or frozen and cook as directed. Alternatively, fully prepare up to 1 day in advance, refrigerate, then reheat in the slow cooker on low for 1 hour or on stovetop 20-30 minutes. Cooked meatballs can be frozen in sauce up to 2 months. Defrost in refrigerator before reheating.
Notes
Meat: you can actually use any ground meat here.
Ground flaxseed: if you don't need or want these to be gluten-free, replace with the same amount of breadcrumbs.
Hot sauce: I like to use Frank's Red Hot Wings but you can use your favorite buffalo sauce.
Test for doneness: I check a few meatballs with a meat thermometer to ensure food safety. You're looking for 165°F (74°C) for poultry.
