Step‑by‑Step Instructions for Keto French Onion Meatloaf
Step 1: Caramelize the Onions
Start by thinly slicing 2 large yellow onions. Heat a skillet over medium-low heat and add 2 tablespoons of olive oil and 1 tablespoon of butter. Cook the onions slowly for 25–30 minutes, stirring occasionally, until they become soft and golden brown. This caramelization process brings out their natural sweetness, which is essential for the flavor of your Keto French Onion Meatloaf. In the last few minutes, stir in 1 teaspoon of fresh thyme and 1 tablespoon of beef broth concentrate.
Step 2: Prepare the Meatloaf Mixture
In a large mixing bowl, combine 1 pound of ground beef, 2 beaten eggs, ½ cup of almond flour, 2 tablespoons of coconut aminos, and ½ teaspoon each of salt and pepper. Gently mix in half of the caramelized onions until just combined—do not overmix, as this can make your meatloaf tough. Your mixture should be slightly sticky but well integrated, ensuring a hearty texture for your Keto French Onion Meatloaf.
Step 3: Shape and Bake
Preheat your oven to 375°F (190°C). Lightly grease a baking sheet or a loaf pan. Transfer the meatloaf mixture onto the prepared surface and shape it into a loaf about 8 inches long. Bake the meatloaf uncovered in the preheated oven for 35–40 minutes, or until the outside is golden and slightly crisp. This initial baking will firm up the meatloaf for the final step.
Step 4: Add Toppings
Once the meatloaf is done baking, carefully remove it from the oven. Layer the top with the remaining caramelized onions and evenly sprinkle 1 cup of shredded Gruyère cheese over the onions. Return the meatloaf to the oven for an additional 10-15 minutes, or until the cheese is melted and bubbly. At this point, the internal temperature of the meatloaf should reach 160°F (71°C), ensuring it is fully cooked.
Step 5: Rest and Serve
After baking, allow the Keto French Onion Meatloaf to rest for about 10 minutes before slicing. This resting period helps the juices redistribute, resulting in a tender meatloaf. For an extra touch, garnish with fresh thyme before serving. Pair with sautéed greens or creamy cauliflower mash for a comforting meal that everyone will love.

Make Ahead Options
These Keto French Onion Meatloaf preparations are perfect for busy weeknights and meal prep enthusiasts! You can prepare the meatloaf mixture and shape it into a loaf up to 24 hours in advance, storing it tightly covered in the refrigerator to maintain quality. The caramelized onions can also be made ahead and kept in an airtight container for up to 3 days. When you’re ready to cook, simply bake the prepared meatloaf and add the onions and cheese during the last stage. This way, you’ll still enjoy that delicious flavor and texture, all while saving time in your hectic schedule—resulting in a comforting dinner with minimal effort!
How to Store and Freeze Keto French Onion Meatloaf

Freezer: For longer storage, wrap individual slices tightly in plastic wrap and then place in a freezer-safe bag. They can be kept for up to 3 months.
Reheating: To reheat, gently steam slices in a skillet with a splash of broth or water to keep them moist. Alternatively, microwave in short intervals until heated through.
Thawing: When ready to eat, thaw overnight in the fridge before reheating for best results. This preserves flavor and texture, making it feel freshly cooked.
