Ingredients
  

  • 2 medium eggplants
  • 2 tablespoons olive oil (plus more for drizzling)
  • 1 pound (450 g) ground beef (80–85% lean works best)
  • 1 small yellow onion, finely diced
  • 2 cloves garlic, minced
  • 1/2 cup crushed tomatoes or tomato passata (no sugar added)
  • 2 tablespoons sugar-free ketchup (optional, for a burger vibe)
  • 1 tablespoon Dijon or yellow mustard
  • 1 teaspoon Worcestershire sauce (check for low-carb brand) or coconut aminos
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon onion powder
  • Salt and black pepper, to taste
  • 1–1 1/2 cups shredded cheese (cheddar, mozzarella, or a blend)
  • 1/4 cup grated Parmesan (optional, for extra flavor)
  • Fresh parsley or chives, chopped, for garnish
  • Optional toppings: sliced pickles, a drizzle of sugar-free ketchup, or extra mustard

Method
 

  1. Prep the oven and eggplants: Heat the oven to 400°F (200°C). Halve each eggplant lengthwise. Score the flesh in a crosshatch pattern, keeping the skin intact. Brush with olive oil and season with salt and pepper.
  2. Roast the “boats”: Place eggplant halves cut-side down on a lined baking sheet. Roast for 20–25 minutes until the flesh is tender and lightly browned.
  3. Scoop carefully: Let the eggplants cool a few minutes. Turn them cut-side up and scoop out most of the flesh, leaving a 1/4-inch border so the shells hold their shape. Roughly chop the scooped eggplant and set aside.
  4. Cook the beef mixture: In a large skillet, warm 2 tablespoons olive oil over medium heat. Add the onion and cook 3–4 minutes until translucent. Stir in the garlic for 30 seconds.
  5. Brown the beef: Add ground beef, breaking it up with a spatula. Cook until browned, about 5–7 minutes. Drain excess fat if needed, but leave a little for flavor.
  6. Season and simmer: Stir in the chopped eggplant, crushed tomatoes, ketchup (if using), mustard, Worcestershire, smoked paprika, oregano, onion powder, salt, and pepper. Simmer 3–5 minutes until slightly thickened and well combined. Taste and adjust seasoning.
  7. Fill the boats: Arrange eggplant shells in a baking dish. Spoon the beef mixture evenly into each one. Top with shredded cheese and a sprinkle of Parmesan, if using.
  8. Bake to finish: Return to the oven for 10–12 minutes, until the cheese is melted and golden at the edges. For a bubbly top, broil 1–2 minutes at the end, watching closely.
  9. Garnish and serve: Let rest 5 minutes. Garnish with chopped parsley or chives. Add optional pickles, a drizzle of sugar-free ketchup, or extra mustard for a true burger feel.
