Preparation Phase & Tools to Use

Before diving into this delicious meatloaf, it’s essential to prepare your kitchen for success. Begin by gathering all your ingredients to ensure a smooth cooking experience. You’ll need basic kitchenware: a cutting board, a large mixing bowl, a skillet for caramelizing the onions, and a crockpot to slow-cook the meatloaf.

For the best results, ensure your skillet is large enough to accommodate all the onions without crowding.

Given the slow cooking nature of this recipe, you don’t need any specialized tools, just a reliable set of cookware that will help you achieve perfectly caramelized onions.

Ingredients

2 lbs ground beef (80/20 blend)
1 cup finely diced yellow onion
1 cup breadcrumbs
2 large eggs
1/2 cup whole milk
3 cloves garlic, minced
1 tablespoon Worcestershire sauce
1 teaspoon fresh thyme leaves
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon onion powder
1/2 teaspoon garlic powder
2 tablespoons chopped fresh parsley
3 large yellow onions, thinly sliced
2 tablespoons unsalted butter
1 tablespoon olive oil
1/2 teaspoon salt (for onions)
1/2 teaspoon sugar (optional)
1/4 cup beef broth
6–8 slices Gruyère cheese
1/2 cup shredded mozzarella (optional)

Instructions

Step 1: Caramelize the Onions

Start off by heating the butter and olive oil in a skillet over medium heat. Once hot, add the sliced onions along with the salt. Stir them frequently as they cook for about 25 to 35 minutes, or until they reach a rich golden brown color. This step is crucial as it develops the sweetness and depth of flavor you want for your meatloaf. If you like, add a pinch of sugar during the cooking process to enhance the caramelization. Once they’ve caramelized, deglaze the pan with the beef broth and cook for an additional 2-3 minutes, then allow them to cool slightly.

Step 2: Prepare the Meatloaf Mixture

In a large mixing bowl, combine the ground beef and finely diced onion. Then, add the breadcrumbs, eggs, whole milk, minced garlic, Worcestershire sauce, thyme, salt, black pepper, onion powder, garlic powder, and parsley. Gently mix everything until just combined. Avoid overmixing to keep the meatloaf tender and juicy.

Step 3: Shape and Cook the Meatloaf

Shape the meat mixture into a firm loaf, making sure to pack it well without being overly compressed. Lightly grease your crockpot or line it with parchment paper for easy cleanup. Place the shaped loaf inside the crockpot, then spoon two-thirds of the caramelized onions on top, reserving the rest for later. Cover the crockpot with its lid and set it to cook on LOW for 6–7 hours, or on HIGH for 3–4 hours, until the meatloaf’s internal temperature reaches 160°F (71°C).

Step 4: Add the Cheese

Once the cooking time is up, top the meatloaf with sliced Gruyère and, if you choose, shredded mozzarella cheese. Cover again and cook on HIGH for an additional 10–15 minutes. This will allow the cheese to melt beautifully and create that gooey topping everyone loves.

Step 5: Slice and Serve

After the cheese has melted, carefully remove the meatloaf from the crockpot. Let it rest for 10–15 minutes before slicing to allow the juices to redistribute. This step is essential for preventing it from falling apart. Serve warm, topped with the reserved caramelized onions.

Variations

Protein: Substitute ground turkey or chicken for a leaner option; adjust seasoning as per preference.
Vegetables: Incorporate diced bell peppers or mushrooms into the meat mixture for added flavor and nutrition.
Spices: Experiment with adding smoked paprika or Italian herbs to the meat mix for a flavor twist.

Cooking Notes

Cooking times may vary based on the size of your crockpot and the thickness of the meatloaf.
Ensure that the internal temperature of the meatloaf reaches 160°F (71°C) to guarantee doneness and safe consumption.

Serving Suggestions

Serve with roasted vegetables or mashed potatoes for a classic hearty meal.
Pair with a simple green salad for a refreshing contrast to the rich meatloaf.

Tips

Caramelizing the onions slowly at medium heat develops their sweetness, creating depth in the overall flavor.
