Form the meat mixture into a loaf shape and place it on the slotted upper part of the broiler pan. This will allow the fat to drain into the bottom drip pan.
Bake for a total of 1 1/2 hours.
10 minutes before it's finished baking, brush the top of the loaf with tomato paste.
For Spicy Mayo:
Stir mayo and sriracha together in a small bowl.
Slice and serve your meatloaf with spicy mayo sauce on the side.
Cauliflower rice is our substitute for the bread crumbs. Cauliflower keeps our meatloaf juicy.Yes, you could serve this meatloaf with a traditional gravy. But spicy mayo made with mayonnaise and Sriracha sauce is a fun way to add another burst of flavor.
