Preheat the oven to 350°F (175°C).
Warm butter in a frying pan over medium heat. Sauté the onion and garlic together for 5 minutes.
Remove the sausage from its casing and add to the pan also. Break apart into smaller pieces and brown all sides evenly, about 8 minutes.
While the sausage browns, whisk 10 eggs in a large bowl. Mix in the cheese, thyme, salt, and pepper.
Transfer meat to an 8×8-inch (20×20 cm) glass baking or casserole dish. Arrange in a single, even layer on the bottom.
Pour the egg mixture over the meat. Gently jiggle or tap the dish so the egg can settle down around the meat.
Bake for 20 minutes, until eggs are set and the top is golden brown. Let rest for 5 minutes before slicing and serving warm with a cup of our Tibetan Butter Tea.

Carnivore Keto Breakfast Ideas
You can never go wrong by starting the day with keto carnivore recipes. Animal foods are extremely nourishing and satiating. When we are filled and satisfied, we won’t struggle with cravings or feel the need to snack all the time. Finally getting the nutrition you need is such a relief!
When we teach keto to clients, we always emphasize the importance of animal-based nutrition. Eat the steaks and you won’t be hungry for the cakes. It’s as simple as steaks over cakes.

We notice that swapping out flour heavy breakfasts like bread, bagels, muffins, and scones in favor of savory meats and eggs generally lead to better fat loss, fewer cravings, and less snacking. Even if the recipes are made with almond flour and coconut flour, which are some of the best ingredients for keto baking, they don’t act the same in our bodies as protein and fat.
I listed some egg-based recipes above but don’t hesitate to start eating meat in the morning! It’s not usually considered a standard breakfast meal but your mind should not get in the way of your progress.
Carnivore Breakfast: Sausage, Egg, and Cheese Casserole
Since the ingredient list in this low carb sausage, egg, and cheese casserole is mostly sausage, egg, and cheese the recipe is easily modified for a carnivore diet.
- Sausage is the meat of choice here but in a pinch, you can substitute ground meat of any kind. Bacon is pretty tasty too. Whatever you choose, pre-cook the meat first.
- Eggs are essential for holding the casserole together. They contain significant amounts of protein and fats with minimal carbs.
- Cheese also works to hold this low carb dish together in a nice presentable portion. Choose any shreddable cheese like Colby, Monterey jack, pepper jack, cheddar, or Swiss. Get creative and use what you have on hand or what you like best.
Carnivore diet recipes consist exclusively of animal protein and fat.
Transform this dish into a carnivore breakfast casserole by omitting the onion, garlic, thyme, and black pepper. With out the plants, there are still some carbs from the dairy foods, but even so, this is practically a no carb breakfast casserole.
In many cases, these ingredients are relatively benign as far as plant toxins go. Once you are ready to reintroduce plant foods to your diet again, the original recipe will be an appropriate keto carnivore dish to make. If you know that you tolerate these foods, enjoy them!
When the time comes, introduce single ingredients one at a time and give a space of three days or so between new foods so you can judge any residual effects.
