Ingredients
  

Meatloaf
  • 1.5 lb lean ground beef (90/10) or ground turkey Use 90/10 beef for best texture; turkey works equally well.
  • 0.5 cup rolled oats Rolled oats help bind and keep the loaf tender.
  • 2 eggs Use large eggs.
  • 0.33 cup whole milk Whole milk adds moisture; swap with low-fat if desired.
  • 1 small onion, grated Grate to distribute vegetables evenly.
  • 1 medium carrot, finely grated Finely grated carrot adds sweetness and moisture.
  • 0.5 cup zucchini, finely grated and squeezed dry Squeeze well to prevent a watery loaf.
  • 3 cloves garlic, minced Minced garlic distributes flavor throughout.
  • 2 tbsp Worcestershire sauce Adds savory depth without much fat.
  • 1 tsp dried thyme Dry thyme complements the tomato glaze.
  • Salt and pepper to taste Season the mixture to taste; keep it simple and balanced.
Tomato Glaze
  • 3 tbsp tomato paste Use tomato paste for a thick, clingy glaze.
  • 1 tbsp honey Honey balances the acidity of the tomato.
  • 1 tsp apple cider vinegar Vinegar brightens the glaze.

Equipment

  • 1 sheet pan

Method
 

Prep and season
  1. Preheat the oven to 350°F and line a loaf pan with parchment so the meatloaf releases cleanly.
  2. Combine lean ground beef (90/10) or ground turkey, rolled oats, eggs, whole milk, grated onion, grated carrot, squeezed-dry zucchini, minced garlic, Worcestershire sauce, dried thyme, salt, and pepper in a bowl until evenly mixed.
  3. Press the mixture firmly into the prepared loaf pan to help it slice neatly.
Glaze and bake
  1. Mix tomato paste, honey, and apple cider vinegar, then spread the glaze evenly over the top.
  2. Bake at 350°F for 55–65 minutes, until the internal temperature reaches 160°F, with a browned top visible through the glaze.
Rest and serve
  1. Rest the meatloaf for 10 minutes before slicing so the juices set and the texture stays tender.

Notes

For the best low-fat texture, squeeze the grated zucchini very dry so the loaf bakes instead of steaming. Refrigerate leftovers in a sealed container for up to 4 days; freeze sliced portions for up to 2 months (thaw overnight in the fridge). For a leaner option, use ground turkey and the same vegetable mix to keep it clean-eating while staying moist.
