Step-by-Step Guide to Making French Onion Meatloaf

Ingredients You’ll Need

For the Meatloaf:

• 1 1/2 pounds ground beef (or a mix of beef and pork)
• 1/2 cup caramelized onions (see instructions below)
• 1/4 cup almond flour
• 1 large egg
• 2 cloves garlic, minced
• 1 teaspoon dried thyme
• 1 teaspoon smoked paprika
• Salt and pepper, to taste

For the Caramelized Onions:

• 2 tablespoons butter or olive oil
• 2 medium onions, thinly sliced
• 1 tablespoon granulated sugar substitute (like erythritol or monk fruit)
• 1/4 cup beef broth (low-sodium preferred)

For the Topping:

• 1/2 cup shredded Gruyere or Swiss cheese
• Optional: Fresh parsley, chopped (for garnish)

Instructions

1. Preheat the Oven :
   • Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease a loaf pan.
2. Caramelize the Onions :
   • Heat the butter or olive oil in a skillet over medium heat.
   • Add the sliced onions and cook, stirring occasionally, for 15-20 minutes until golden brown and caramelized.
   • Stir in the sugar substitute and beef broth, scraping up any browned bits from the bottom of the pan. Cook for an additional 2-3 minutes until the liquid evaporates. Set aside.
3. Prepare the Meatloaf Mixture :
   • In a mixing bowl, combine the ground beef, caramelized onions, almond flour, egg, minced garlic, thyme, smoked paprika, salt, and pepper. Mix gently until just combined—do not overmix.
4. Shape the Meatloaf :
   • Transfer the mixture to the prepared baking sheet or loaf pan. Shape it into a loaf and smooth the top.
5. Bake the Meatloaf :
   • Bake for 30 minutes, then remove from the oven and sprinkle the shredded cheese evenly over the top.
   • Return to the oven and bake for an additional 10-15 minutes, or until the internal temperature of the meatloaf reaches 160°F (71°C).
6. Rest and Serve :
   • Let the meatloaf rest for 5-10 minutes before slicing. Garnish with fresh parsley if desired.
   • Serve warm with your favorite low-carb sides like roasted vegetables or cauliflower mash.
