Prep. Preheat the oven to 400˚F. Lightly grease a baking dish with cooking spray and set aside.
Sauté the vegetables. Heat the oil in a skillet set over medium heat. To the heated oil, add the onion and celery and cook for 4 to 5 minutes, or until softened. Stir in the garlic and cook for 15 seconds.
Mix in the herbs and spices. Add thyme, oregano, chili powder, and paprika; stir and cook for 30 seconds. Remove from the heat and transfer the veggies to a large mixing bowl.
Combine with the remaining ingredients. To the mixing bowl, add the ground beef, shredded cheese, nut flour, parmesan cheese, eggs, worcestershire sauce, salt, and pepper. Mix and stir until everything is well combined. Do not overmix.
Wrap it with the bacon. Transfer the beef mixture to the baking dish and shape it into a loaf. Arrange the bacon slices on top, and tuck the ends under the loaf.
Cook. Transfer it to the oven and cook for about 50 minutes to 1 hour, or until the beef is cooked through and the bacon is crispy. Cover the dish with foil IF the bacon is cooking too quickly.
Serve. Remove the meatloaf from the oven and let it rest for 10 to 15 minutes before cutting and serving.
Notes
Meatloaf Mixture: Mix the meatloaf ingredients just until combined, and try not to overmix because that will result in a tough meatloaf.
Tomato: This meatloaf recipe is without tomatoes or tomato sauce because of the sugar content, but if you want a tomato flavor, add in couple teaspoons of tomato paste.
Bacon: If you want to make this without the bacon, that is okay to do, but keep in mind that the bacon does add flavor and extra juiciness. Turkey bacon is also good in this recipe.
Cheese: I love me some cheese in meatloaf. I like to use shredded mozzarella, but you can also use shredded cheddar or pepper jack, or whatever you like.
Slicing Keto Meatloaf: Due to the absence of breadcrumbs, low carb meatloaf tends to fall apart if not handled slowly and carefully. I use a cake server to pick up a slice and transfer it to a dinner plate.
