Preheat and prep: Set your oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease a loaf pan. For crispier edges and better fat drainage, shape your loaf on a baking sheet rather than using a pan.

Sauté aromatics (optional but recommended): In a small skillet, warm oil over medium heat. Cook the minced onion with a pinch of salt for 4–5 minutes until softened. Add garlic for the last 30 seconds. Let cool slightly. This step removes raw onion bite and adds sweetness.

Mix the binder: In a large bowl, whisk the eggs, sugar-free ketchup, Worcestershire, and Dijon. Stir in almond flour, Parmesan, smoked paprika, Italian seasoning, onion powder, garlic powder, salt, and pepper until evenly combined.

Add the meat: Gently fold in the ground beef, sautéed onion and garlic, and parsley. Mix with your hands or a fork just until combined. Do not overmix—that can make the loaf dense.

Shape the loaf: Transfer the mixture to your lined sheet or loaf pan. Form a tight, even loaf about 9 inches long. Smooth the top to prevent cracks.

Glaze lightly: Brush the top with 2–3 tablespoons of sugar-free ketchup. For extra shine and tang, you can mix in a little Dijon or a splash of apple cider vinegar.

Bake: Cook for 50–60 minutes, or until the internal temperature reaches 160°F (71°C). If the top is browning too fast, tent with foil for the last 10–15 minutes.

Rest, then slice: Let the meatloaf rest for at least 10 minutes before cutting. This helps the juices redistribute and keeps slices intact.

Serve: Pair with cauliflower mash, roasted green beans, or a simple side salad. Spoon any pan juices over the slices for extra flavor.
