Keto French Onion Meatloaf Ingredients
For the Meatloaf:
- 2 lbs ground beef (80/20 blend for maximum juiciness)
- 3 large yellow onions, thinly sliced
- 3 tbsp butter (for caramelizing)
- ¾ cup almond flour
- 2 large eggs
- 6 oz Gruyere cheese (4 oz cubed, 2 oz shredded for topping)
- ½ cup beef broth
For Seasoning:
- 2 tsp fresh thyme (or 1 tsp dried)
- 1 tsp garlic powder
- 1 tsp salt
- ½ tsp black pepper
- 1 tsp Worcestershire sauce
The almond flour acts as the perfect ground beef recipes low carb binder, mimicking breadcrumbs without adding any unnecessary carbs. Gruyere cheese is traditional for French onion flavor, but Swiss makes an excellent substitute if that’s what you have on hand.
How to Make Keto French Onion Meatloaf
1. Caramelize Those Onions: Melt the butter in a large skillet over medium heat. Add the sliced onions and a pinch of salt, stirring to coat. Cook for 25-30 minutes, stirring every few minutes, until the onions turn deep golden brown and taste sweet and jammy. Transfer to a plate and let them cool completely—this step is crucial.
2. Build the Meatloaf Mixture: Preheat your oven to 375°F. In a large bowl, combine the ground beef, almond flour, eggs, beef broth, Worcestershire sauce, thyme, garlic powder, salt, and pepper. Add half of the cooled caramelized onions and the 4 oz of cubed Gruyere cheese. Mix gently with your hands just until everything is evenly distributed—overmixing makes tough meatloaf.
3. Shape Your Loaf: Transfer the mixture to a parchment-lined baking sheet and shape it into a rectangular loaf about 9 inches long and 5 inches wide. Alternatively, press it into a standard loaf pan, but a free-form loaf on a baking sheet allows fat to drain away for better texture.
4. Bake to Perfection: Slide the meatloaf into your preheated oven and bake for 45-50 minutes, until the internal temperature reaches 160°F on an instant-read thermometer. The top should be nicely browned and the edges slightly caramelized.
5. Add the Cheesy Topping: Remove the meatloaf from the oven and spread the remaining caramelized onions across the top. Sprinkle with the 2 oz of shredded Gruyere cheese. Switch your oven to broil and return the meatloaf for 2-3 minutes, watching carefully, until the cheese is melted, bubbly, and golden in spots.
6. Rest Before Slicing: Let the meatloaf rest for 10 minutes before slicing. This allows the juices to redistribute throughout the loaf, ensuring every slice is moist and holds together beautifully.
Tips for the Best Keto French Onion Meatloaf
Cool Those Onions Completely: This might seem tedious, but adding hot caramelized onions directly to the raw meat mixture will start cooking the eggs prematurely, creating an unpleasant texture. Spread them on a plate and let them cool to room temperature before mixing—it only takes about 10 minutes.
Mix with a Gentle Hand: The more you work ground meat, the denser and tougher it becomes. Use your hands to combine ingredients just until everything is evenly distributed, then stop. A slightly rough, uneven mixture creates a more tender, restaurant-quality meatloaf.
Always Rest Before Slicing: Those 10 minutes of resting time aren’t optional. When you slice into a freshly baked meatloaf, all those delicious juices run out onto your cutting board. Letting it rest allows the proteins to relax and reabsorb moisture, giving you clean slices that hold their shape and stay juicy.
Keto French Onion Meatloaf Variations
This elegant base recipe welcomes creative twists that keep it interesting meal after meal.
Mushroom Lovers: Sauté 8 oz of sliced mushrooms along with the onions for the full French onion soup experience. The earthy mushrooms add another layer of umami that pairs beautifully with the beef and cheese.
Mini Meatloaves: Divide the mixture among 12 greased muffin cups and bake at 375°F for just 20-22 minutes. These individual portions cook faster, create more caramelized edges, and make portion control effortless for meal prep.
Provolone Substitute: Can’t find Gruyere? Sharp provolone delivers similar nutty, melty goodness at a fraction of the price. Aged white cheddar also works beautifully if you prefer a sharper cheese flavor.

A simple mixed green salad with a tangy vinaigrette cuts through the richness and rounds out the plate with crisp vegetables.
Keto French Onion Meatloaf FAQs
Can I use crushed pork rinds instead of almond flour in this Keto French Onion Meatloaf? Absolutely! Crushed pork rinds make an excellent zero-carb binder that works just as well as almond flour. Use ¾ cup of finely crushed pork rinds (about 2 oz by weight) and let the mixture sit for 5 minutes before shaping—this allows the rinds to absorb moisture and bind everything together beautifully.
Is store-bought French Onion soup mix keto-friendly? Unfortunately, most packaged soup mixes contain cornstarch, sugar, and maltodextrin as fillers, which add unnecessary carbs. For truly ground beef recipes healthy and keto-compliant, it’s better to use real caramelized onions, beef broth, and fresh herbs. You get better flavor and complete control over what goes into your food.
Can I freeze this Keto French Onion Meatloaf? Yes! Bake the meatloaf completely, let it cool, then slice it into individual portions. Wrap each slice tightly in plastic wrap, then place them in a freezer-safe container or bag. They’ll keep for up to 3 months. Reheat individual slices in the microwave for 2-3 minutes or in a 350°F oven for 15 minutes.
