Why This Recipe Works

The reason this recipe works so well is that it uses a combination of ground beef, onions, and spices to create a rich, savory flavor profile. The onions are cooked until they're soft and caramelized, which adds a depth of flavor to the meatloaf.

The use of almond flour as a binder helps to keep the meatloaf moist and tender, while also adding a nutty flavor. The eggs help to bind the mixture together, while the cheese adds a creamy, melty texture.

The cooking process is also important, as it helps to create a nice crust on the outside of the meatloaf while keeping the inside tender and juicy. By cooking the meatloaf in a hot oven, we can achieve a nice browning on the outside, which adds texture and flavor to the dish.

Overall, this recipe is a great example of how a few simple ingredients can be combined to create a delicious, satisfying meal that's perfect for a low-carb keto diet.

How to Make Beef And Onion Meatloaf

1
Preheat the oven to 375°F (190°C).
2
In a large mixing bowl, combine the ground beef, chopped onion, minced garlic, almond flour, grated cheddar cheese, chopped parsley, eggs, salt, black pepper, and paprika. Mix the ingredients together with your hands or a wooden spoon until they are just combined. Be careful not to overmix the mixture.
3
Transfer the mixture to a 9x5-inch loaf pan and smooth the top with a spatula.
4
Place the loaf pan in the oven and bake for 40-45 minutes, or until the meatloaf reaches an internal temperature of 160°F (71°C).
5
While the meatloaf is baking, melt the butter in a small saucepan over medium heat.
6
After the meatloaf has baked for 30 minutes, brush the melted butter over the top of the meatloaf.
7
Continue baking the meatloaf for an additional 10-15 minutes, or until it reaches an internal temperature of 160°F (71°C).
8
Remove the meatloaf from the oven and let it rest for 10-15 minutes before slicing and serving.
9
Slice the meatloaf into thick slices and serve hot, garnished with additional chopped parsley if desired.
10
To check for doneness, insert an instant-read thermometer into the center of the meatloaf. The internal temperature should be at least 160°F (71°C).
11
Let the meatloaf rest for a few minutes before slicing and serving. This will help the juices to redistribute and the meatloaf to stay moist.
