Here is the recipe from Cook's Country, part of the America's Test Kitchen group. ATK's cooks will make dozens of variations of meatloaf until they come up with one that tastes great and is foolproof. Notice that it is a freeform meatloaf. Meatloaf pans hold the grease and juices, making your meatloaf soggy, plus only the top can brown since it is the only part that is exposed. Do yourself a favor and save the pan for breads.
Glazed Meatloaf
Over the years, meatloaves have been dressed up and down every which way. Our goal was to make meat loaf special again. Here’s what we discovered:
Test Kitchen Discoveries
Cutting ground beef with an equal portion of sweet ground pork balances the beefy flavor. We flavored the loaf with traditional seasonings: salt, pepper, Dijon mustard, Worcestershire sauce, thyme, parsley, sautéed onion, and garlic.
To add moisture and structure, we used a panade of milk and saltines (rather than bread), which provided a mild saltiness. Two whole eggs, plus an extra yolk for added richness, proved the perfect binder to hold the loaf together.
Combining the panade in a food processor and then pulsing it with the meat gave the loaf the most cohesive, tender structure.
To evaporate the surface moisture that was inhibiting the formation of a crust, we broiled the meat loaf prior to baking and glazing with brown sugar and ketchup. This worked beautifully, and the browned crust gave the glaze—applied twice for extra effect—something to hang onto.
Glazed Meatloaf
Both ground sirloin and ground chuck work well here, but avoid ground round—it is gristly and bland.
Serves 6 to 8
Glaze
1 cup ketchup
1/4 cup packed brown sugar
2 1/2 tablespoons cider vinegar
1/2 teaspoon hot sauce
Meatloaf
2 teaspoons vegetable oil
1 onion , chopped fine
2 garlic cloves , minced
2/3 cup Saltine crackers , crushed (about 17 crackers)
1/3 cup whole milk
1 pound 90-percent lean ground beef (see note)
1 pound ground pork
2 large eggs plus 1 large yolk
2 teaspoons Dijon mustard
2 teaspoons Worcestershire sauce
1/2 teaspoon dried thyme
1/3 cup finely chopped fresh parsley
Salt and pepper
Line a rimmed baking sheet with foil and coat lightly with cooking spray. This will be the pan you cook your meatloaf on.
1. MAKE GLAZE Whisk all ingredients in saucepan until sugar dissolves. Reserve ¼ cup glaze mixture, then simmer remaining glaze over medium heat until slightly thickened, about 5 minutes. Cover and keep warm.
2. COOK VEGETABLES Heat oil in nonstick skillet over medium heat until shimmering. Cook onion until golden, about 8 minutes. Add garlic and cook until fragrant, about 30 seconds. Transfer to large bowl.
3. PROCESS MEAT Process saltines and milk in food processor until smooth. Add beef and pork and pulse until well combined, about ten 1-second pulses. Transfer meat mixture to bowl with cooled onion mixture. Add eggs and yolk, mustard, Worcestershire, thyme, parsley, 1 teaspoon salt, and ¾ teaspoon pepper to bowl and mix with hands until combined.
4. BROIL Adjust oven racks to upper (about 4 inches away from broiler element) and middle positions and heat broiler. Transfer meat mixture to prepared baking sheet and shape into 9- by 5-inch loaf. Broil on upper rack until well browned, about 5 minutes. Brush 2 tablespoons uncooked glaze over top and sides of loaf and then return to oven and broil until glaze begins to brown, about 2 minutes.
5. BAKE Transfer meatloaf to middle rack and brush with remaining uncooked glaze. Reduce oven temperature to 350 degrees and bake until meat loaf registers 160 degrees, 40 to 45 minutes. Transfer to carving board, tent with foil, and let rest 20 minutes. Slice and serve, passing cooked glaze at table.
