Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
In a large mixing bowl, combine the lean ground beef, egg, almond flour, minced garlic, finely grated yellow onion, sea salt, black pepper, dried oregano, and smoked paprika.
Gently mix the ingredients by hand until just incorporated, being careful not to overwork the meat to ensure the meatballs remain tender.
Scoop and roll the mixture into approximately 14 small, bite-sized meatballs, each about one inch in diameter.
Heat the olive oil in a large oven-safe skillet over medium-high heat until shimmering.
Add the meatballs to the skillet and sear for 2 minutes per side until a golden-brown crust forms on the exterior.
Transfer the skillet directly into the preheated oven and bake for 8 to 10 minutes until the internal temperature reaches 160°F.
Remove from the oven, garnish with fresh chopped parsley, and serve immediately as savory protein bites.
