Ingredients
Meatloaf Mixture
- 1 lb ground beef (organic, grass-fed preferred)
- 1 large egg
- ¼ cup breadcrumbs
- ½ tsp black pepper
- ½ tsp sea salt
Caramelized Onions
- 2 large onions (about 4 cups, thinly sliced)
- 1 tbsp olive oil
- 3 cloves garlic, minced
- 4 sprigs fresh thyme
- 1.5 tbsp Worcestershire sauce
- 1 tsp balsamic vinegar
Topping
- 1 cup Gruyère cheese, grated
Instructions
- Caramelize the onions: Heat 1 tablespoon of olive oil over medium heat in a large skillet. Add the thinly sliced onions and cook slowly, stirring occasionally, for 25 to 30 minutes until the onions are deeply golden and caramelized.
- Add flavorings to onions: Stir in the minced garlic, fresh thyme sprigs, Worcestershire sauce, and balsamic vinegar. Cook for an additional 2 to 3 minutes to meld the flavors, then season with salt. Remove from heat and allow the onions to cool slightly.
- Prepare the meatloaf mixture: In a large mixing bowl, combine the ground beef, egg, breadcrumbs, black pepper, sea salt, and half of the caramelized onions. Mix gently with your hands or a spoon until just combined, being careful not to overmix to keep the meatloaf tender.
- Shape and bake: Preheat your oven to 325°F (163°C). Shape the meat mixture into a slightly flattened loaf and place it on a parchment-lined baking sheet or in a loaf pan. Bake for 30 minutes to partially cook the meatloaf.
- Add onion topping and cheese: Remove the partially baked meatloaf from the oven. Spoon the remaining caramelized onions evenly over the top of the loaf, then sprinkle the grated Gruyère cheese over the onions.
- Broil the cheese: Increase the oven temperature to broil. Place the meatloaf under the broiler for about 5 minutes, watching carefully until the cheese melts, bubbles, and turns golden brown. Broiler times may vary, so keep a close eye to avoid burning.
- Rest and serve: Remove the meatloaf from the oven and let it rest for 5 to 10 minutes to help it set and hold its shape when slicing. Serve warm alongside your favorite sides.
Notes
- If the onions start sticking or browning too quickly while caramelizing, add 1–2 tablespoons of water or broth to deglaze the pan and ensure even cooking.
- Allow the caramelized onions to cool before mixing them into the raw meat to prevent melting the fat and creating a dense meatloaf.
- Mix the meatloaf ingredients gently to avoid overworking the meat, which can make the loaf tough.
- A slightly flattened loaf cooks more evenly and gives more surface area for the onion and cheese topping.
- To check doneness, use a meat thermometer to ensure the internal temperature reaches 160°F (71°C) before serving.
- Broilers vary in intensity; watch closely during the final minutes to prevent the cheese from burning.
- Let the meatloaf rest for 5–10 minutes before slicing so it holds together neatly.
- For a gluten-free version, substitute regular breadcrumbs with gluten-free breadcrumbs without other recipe changes.
