Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Ground beef (80/20 blend recommended)
Yellow onion (thinly sliced)
Garlic (minced)
Eggs
Almond flour (as a low-carb binder)
Beef broth or French onion soup broth (low-carb version)
Worcestershire sauce
Dijon mustard
Salt and pepper
Shredded Swiss or Gruyère cheese
Butter or olive oil (for caramelizing onions)
Fresh thyme or dried thyme (optional)

Directions

Preheat your oven to 350°F (175°C).
In a skillet, heat butter or olive oil over medium heat. Add sliced onions and cook slowly, stirring occasionally, until deep golden brown and caramelized (about 20-25 minutes). Add minced garlic during the last few minutes. Remove from heat and let cool slightly.
In a large mixing bowl, combine ground beef, eggs, almond flour, caramelized onions (reserve a few tablespoons for topping), beef broth, Worcestershire sauce, Dijon mustard, salt, pepper, and thyme if using. Mix gently until just combined.
Shape the mixture into a loaf and place it in a greased loaf pan or on a baking sheet lined with parchment paper.
Spread the reserved caramelized onions evenly on top of the meatloaf. Sprinkle shredded Swiss or Gruyère cheese over the onions.
Bake for 50-60 minutes, or until the internal temperature reaches 160°F (71°C).
Let the meatloaf rest for 10 minutes before slicing and serving.
