Method
Preparation
Preheat oven to 350°F (180°C).
In a large bowl, mix egg, gluten-free oats (or breadcrumbs), Worcestershire sauce, salt, pepper, mustard, and ketchup. Let sit for 2–3 minutes.
Combine Ingredients
Add ground meat, onion, zucchini, and carrot. Mix gently until just combined.
Shape the Loaf
Press mixture into a loaf pan lined with parchment, or shape by hand on a baking sheet.
Make the Glaze
Mix ketchup, brown sugar, and ground mustard. Spread half over the loaf halfway through baking for a caramelized finish.
Bake
Bake for 1 hour, or until internal temperature reaches 160°F (70°C). Rest 10 minutes before slicing.
Pro tip: Never cut meatloaf while hot—it will crumble!
Notes
For a vegan version, swap meat for lentils, walnuts, and mushrooms; replace egg with flaxseed meal and water. Store in an airtight container for up to 4 days. Freeze wrapped for up to 3 months.
