Do I put the sauce on before or after baking meatloaf?
Both, if you want the best texture. Brush a thin layer on for most of the bake so it sets and clings, then add a second layer near the end to get that shiny, sticky finish.
How do I keep meatloaf sauce from burning?
Sugar can scorch if the oven runs hot or the sauce is applied too early in a thick layer. Keep your oven at 350°F, apply the first layer thin, and add the heavier glossy layer in the last 10 to 15 minutes. If it starts to darken too fast, tent loosely with foil.
Can I make meatloaf sauce without brown sugar?
Yes. Swap in honey or maple syrup (start with 1 1/2 tablespoons), or use a little white sugar plus a tiny pinch of molasses if you have it.
Can I use barbecue sauce instead of ketchup?
You can, but it changes the vibe. If you use barbecue sauce, reduce the brown sugar a bit and taste before adding vinegar since many barbecue sauces are already sweet and tangy.
My sauce tastes too sweet. How do I fix it?

My sauce tastes too tangy. How do I fix it?
Stir in 1 to 2 teaspoons brown sugar or ketchup. Let it sit for a minute and taste again. It mellows out as it warms and bakes.
Can I make this sauce ahead of time?
Yes. Whisk it together up to 2 to 3 days ahead and refrigerate in an airtight container. Stir before using since it can thicken slightly as it sits.
