Savory Buttermilk Meatloaf - cooking recipe

Ingredients

Meatloaf:
2 tablespoons butter
1 yellow onion, diced
2 1/2 pounds ground chuck
1 cup dry bread crumbs
3/4 cup buttermilk
1/2 cup ketchup
2 eggs, beaten
1 tablespoon Worcestershire sauce
2 1/2 teaspoons salt
1 teaspoon ground black pepper
1 teaspoon hot sauce
1/2 teaspoon dried tarragon
1/2 teaspoon Italian seasoning
Glaze:
1/4 cup brown sugar
1 tablespoon Dijon mustard
1 teaspoon cider vinegar

Preparation

Preheat oven to 350 degrees F (175 degrees C). Line a baking sheet with a silicone baking mat.
Melt butter in a skillet over medium-high heat. Saute onion in hot butter until soft and translucent, 6 to 7 minutes. Cool to room temperature.
Combine cooled onion, beef chuck, bread crumbs, buttermilk, ketchup, eggs, Worcestershire sauce, salt, black pepper, hot sauce, tarragon, and Italian seasoning in a bowl; mix together with a fork and let sit until breadcrumbs absorb moisture, about 10 minutes.
Turn meatloaf mixture out into the center of the prepared baking sheet and form into a 9x5-inch loaf.
Bake in the preheated oven for 45 minutes. While meatloaf is baking, whisk brown sugar, mustard, and cider vinegar together in a small bowl. Spread brown sugar glaze over the top of the meatloaf and continue baking until no longer pink in the center, about 30 minutes more. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
