½ tablespoon (30 mililitres) extra-virgin olive oil
½ yellow onion, small diced
3 cloves garlic, minced
1 teaspoon (5 grams) fresh thyme leaves
4 teaspoons (20 grams) kosher salt
2 teaspoons (10 grams) ground black pepper
3 tablespoons (45 grams) tomato paste
4 tablespoons (60 mililitres) Worcestershire sauce
¼ cup (60 mililitres) chicken broth
1½ pounds (680 grams) ground beef (80% lean, 20% fat)
1 cup (120 grams) unseasoned breadcrumbs
2 large eggs, whisked
⅓ cup (75 grams) ketchup
2 tablespoons (30 grams) parsley, chopped, for garnish
Heat a large sauté pan over medium-high heat. Add extra-virgin olive oil to coat the pan evenly, then add the onions, garlic, thyme, salt, and pepper. Cook until the onions are translucent, about 5 to 8 minutes.
Add the tomato paste and brown over low heat for 3 minutes. Stir in the Worcestershire sauce and chicken broth, then turn off the heat.
Combine the ground beef, garlic mixture, breadcrumbs, and whisked eggs in a large mixing bowl. Shape the meatloaf into an oval loaf on a cutting board and set aside.
Cut a square sheet of parchment paper to fit the crisper plate of the Cosori Smart Air Fryer.
Place the crisper plate into the air fryer basket, then place the parchment paper square onto the crisper plate, followed by the meatloaf.
Spread the ketchup across the top of the meatloaf.
Select the Bake function, adjust temperature to 335°F (165°C) and time to 45 minutes, then press Start/Pause.
Remove the meatloaf when done and allow the meatloaf to set and cool for 10 minutes before transferring to a serving platter to slice and serve.
Garnish the top with chopped parsley and serve immediately.
