Heat the olive oil in a large cast-iron or heavy-bottomed skillet over medium-high heat.
Add the diced yellow onion and minced garlic to the pan, sautéing for 3-4 minutes until the onion is translucent and fragrant.
Add the ground venison and ground beef to the skillet, breaking the meat apart with a wooden spoon.
Cook the meat for 7-9 minutes, stirring occasionally, until it is thoroughly browned and no pink remains.
Stir in the sea salt, black pepper, smoked paprika, and dried oregano to evenly coat the meat mixture.
In a small bowl, whisk together the cottage cheese and the egg until well combined.
Reduce the heat to low and pour the egg and cottage cheese mixture over the meat.
Stir constantly for 1-2 minutes until the mixture thickens and coats the meat in a creamy, velvety sauce without scrambling the eggs too hard.
Remove from heat and serve immediately while hot.
