Preheat the oven to 375 degrees and line a loaf pan with parchment paper.
In a large bowl, combine the ground beef, almond flour, chopped sun-dried tomatoes, egg, onion, garlic, Italian seasoning, Parmesan cheese, salt, and pepper.
Mix with clean hands until the ingredients are evenly distributed but not overworked.
Press the mixture firmly into the prepared loaf pan, smoothing the top.
Bake for 45 to 50 minutes until the internal temperature reaches 160 degrees.
Remove from the oven and let the meatloaf rest for 10 minutes before slicing.
