This Meatloaf Recipe without Bread Crumbs delivers all the nostalgic comfort of a classic meatloaf while skipping the traditional fillers entirely. Grated zucchini, carrots, and eggs act as smart binders that keep the loaf moist, tender, and perfectly sliceable — making it naturally lower in carbs and suitable for keto, paleo, or gluten-free lifestyles. Topped with a sweet and tangy caramelized glaze, this hearty, protein-forward dinner is weeknight-easy and meal-prep friendly.

Instructions
Preheat your oven to 350°F (175°C) and lightly grease a 9x5 inch loaf pan or line it with parchment paper.
Grate the zucchini and carrots; place the zucchini in a clean kitchen towel and squeeze firmly over the sink to remove as much moisture as possible. Finely dice the onion and mince the garlic.
In a small bowl, whisk together the beaten eggs, ketchup, Worcestershire sauce, and Dijon mustard until well combined; set aside.
In a large bowl, combine the ground beef, squeezed zucchini, grated carrots, onion, garlic, Parmesan, wet ingredient mixture, and all seasonings. Mix gently with your hands until just combined — do not overmix.
Transfer the mixture to the prepared loaf pan and press into an even layer, smoothing the top and eliminating any air pockets.
Whisk together the ketchup, brown sugar, and apple cider vinegar; spread half the glaze over the top of the uncooked meatloaf and reserve the rest.
Bake on the middle rack for 45 minutes, then spread the remaining glaze on top and bake for an additional 15 minutes, until the internal temperature reaches 160°F (71°C).
Let the meatloaf rest in the pan for 10 minutes before transferring to a cutting board and slicing into thick portions. Serve immediately.
Notes
Squeeze the zucchini thoroughly: Removing as much moisture as possible is the single most important step — excess water will prevent the loaf from binding and holding its shape.
Don't overmix: Mix just until the ingredients are evenly distributed. Overworking the meat develops too much protein structure and results in a tough, dense loaf.
Always use a meat thermometer: Insert into the center of the loaf and look for 160°F (71°C). Oven temperatures vary, so don't rely on timing alone.
Rest before slicing: A full 10-minute rest allows the juices to redistribute and makes the loaf much easier to slice cleanly without falling apart.
Make ahead: Mix and shape the loaf up to 24 hours in advance, cover tightly, and refrigerate. Add 5–10 minutes to the bake time since it starts cold.
Egg-free option: Replace the 2 eggs with 2 flax eggs (2 tbsp ground flaxseed + 6 tbsp water, rested 5 minutes until gel-like). Texture will be slightly different but still holds well.
Lean meat tip: If using ground turkey or chicken, add 1 tbsp olive oil to the mixture and an extra egg to compensate for lower fat content.
Storage: Wrap cooled meatloaf tightly and refrigerate for up to 4 days. Reheat slices covered with foil at 350°F with a splash of beef broth, or microwave covered with a damp paper towel on medium power for 1–2 minutes.
Freezer friendly: Wrap individual slices in plastic wrap, place in a freezer bag, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Room temperature ingredients: Let eggs and refrigerated vegetables sit out for 20 minutes before mixing to ensure even cooking throughout the loaf.
