What do you get when you cross French Onion soup with hearty meatloaf? You get one of my family’s favorite dinner recipes, that’s what you get!
I have a long-standing love of keto meatloaf, and make it frequently throughout the fall and winter. It’s a guaranteed hit in my family. But sometimes you want to shake things up a little. Adding some sweet caramelized onions and Gruyere turns a regular meatloaf into a mouthwatering masterpiece.
I am not exaggerating when I say that it’s one of the best keto dinner recipes you will ever make.
Why we love it
There are a few things that make a meatloaf good. Juiciness is paramount, as is flavor. And this French Onion Meatloaf meets both of those requirements. The caramelized onions add richness and depth, and the Gruyere and fresh thyme are perfect complements.
It’s an easy recipe to make too. Caramelizing the onions properly does take some time, but it’s worth it. And you can break up the process and do the onions ahead of time, even up to two days.
The end result is a seriously delicious dish that no one can resist. And with 34g of protein and only 2.6g of carbs, it’s a perfect keto comfort food recipe.
Reader Reviews
“Wow! Just made this for dinner this evening. Best meatloaf I’ve ever had. My husband’s comment…this is REALLY good! The caramelized onions and Gruyère cheese take it over the top in flavor. I used grass fed ground beef and organic bulk pork. Thank you for this recipe! It’s a keeper!” — Mary
“I’ve made this meatloaf several times and my family loves it! My wife works late than me so I usually cook dinner. She was always proud of her traditional meatloaf (it’s great btw) but likes this one better. As for the pork rinds, I’ve found that Julio’s seasoned pork rinds are always fresh and delicious.” — David
“Thank you for SO SO SO many amazing recipes! My husband declared this ‘the best meatloaf you’ve ever made!’”’ And told me that this is the only meatloaf I ever need to make again. This is incredibly high accolades from a man who loves meatloaf! Thank you so much! You are at our dinner table more often than not- and you will be for many many years!” — Aimee
Ingredients you need
- Butter: For the best flavor when sautéing the onions, use butter or bacon grease. You could use oil, if you don’t have either of these.
- White onion: You can also use yellow onions.
- Fresh thyme: I prefer the flavor of fresh thyme, but you can use dried thyme if that’s all you have.
- Ground meat: I used a combination of ground pork and beef for more flavor. You can use just ground beef, if you prefer. You could use ground turkey or chicken, but be careful not to over bake it as it could dry it quickly.
- Pork rinds: For the binder, I used crushed pork rinds, but you could also use ½ cup almond flour instead.
- Egg: You will need one large egg.
- Gruyere cheese: You can use any melty cheese like mozzarella, Swiss, or even sharp cheddar.
- Pantry staples: Onion powder, black pepper and salt.
Step by Step Directions
1. Sauté the onions: In a large skillet over low heat, melt the butter or bacon grease. Once melted, add the sliced onions and toss to coat. Sprinkle with salt and cook, stirring frequently, until the onions are soft and golden brown, 15 to 20 minutes.
2. Add the thyme: Stir in the thyme leaves, cook one more minute, then remove from heat and set aside.
3. Mix up the meatloaf: In a large bowl, combine the ground meat, pork rinds, onion powder, pepper, and salt. Stir in the egg and half of the caramelized onions, then use your hands to thoroughly combine.
4. Bake the meatloaf: Transfer to a large rimmed baking sheet lined with parchment paper, and form the mixture into a loaf about 5 by 9 inches. Bake at 350ºF for 40 to 50 minutes, until the internal temperature reaches 160F. Remove and turn off the oven.
5. Add the cheese: Top with the shredded cheese and the remaining onions and place back in the warm oven to melt the cheese, about 5 minutes.
Tips for Success
Take your time to caramelize the onions. Although easy to do, it’s a slow process and needs patience. You don’t want them to get brown and crisp, but instead become tender as they caramelize.
Let the meatloaf cool for 10 to 15 minutes before slicing if you want nice clean slices!
Frequently Asked Questions
Store the leftovers in the fridge for up to 5 days. You can also freeze the finished, cooked meatloaf. Wrap it up tightly to avoid freezer burn and freeze for up to two months.
You have lots of great options to replace the breadcrumbs in traditional meatloaf. Many people use almond flour or another nut flour. You can also use crushed pork rinds. Both result in delicious tender meatloaf that is grain-free and low carb.
