Homemade Paleo skillet meatballs get a delicious makeover with flavorful caramelized onions, a dash of balsamic vinegar, and (optional) sprinkling of mozzarella cheese. The whole family will RAVE over these healthy skillet meatballs!
0 Melt 2 tablespoons of the butter in a large skillet (cast-iron is a good choice) over medium heat. Add the onions, season with the sea salt, stir, and then cook over medium heat (stirring continuously) for 30 minutes to 1 hour, or until the onions have reduced significantly in size and have developed a deep caramel color.
1 Mix the onions into the ground meat with the black pepper until evenly incorporated.
2 Melt the additional 2 tablespoons of butter in the skillet and preheat the oven to 400 F. Roll the meat into 2 tablespoon-sized meatballs and place them in the skillet. Repeat for the entire batch and then drizzle the tops of the meatballs with the balsamic vinegar.
3 Bake at 400 F for 35 minutes, or until the top of the meatballs are starting to brown.
4 Remove from the oven, add the optional cheese and return to the oven for an additional 3 to 5 minutes, or until the top of the cheese is melted and starting to brown.
5 Enjoy warm over zucchini noodles, gluten-free rice noodles, mashed cauliflower, or mashed potatoes.
