Hit The Snooze Button.
I wish I could tell you that I’m a morning person. That I wake up happy, peppy, and excited. That I start every day with a nice long jog. That I have only one cup of coffee. But I would never lie to you. So here’s the truth: I see mornings as a form of torture. The bright light, the grogginess, the to-do list.
But after a few cups of coffee and a hearty meal, I’m back to my normal, happy, peppy self. The problem is that hearty breakfast I mentioned — Making that requires your eyes to be fully open, and your mind to be operational.
Enter this low carb breakfast casserole.
It’s meal prep that doesn’t skimp on flavor. A casserole that isn’t loaded with carbs.
The ideal breakfast for those of us who never have time for breakfast. Who are feeding a crowd. Who hate mornings. Who aren’t low carb. Who love meat. Who love cheese. Basically, this casserole is for all of us. So prep it, slice it, and enjoy hitting the snooze button all week long 😴❤️ – Linds x

Important Ingredient Notes
- Italian sausage – spicy or mild will do. If you can only find links, use a knife to slice each sausage down the center, press out the sausage, and discard the casing.
- Avocado or vegetable oil
- Veggies – Onion and bell pepper.
- Salt + Pepper
- Eggs
- Heavy cream
- Tabasco – We’re only adding a little, which adds no heat, rather some complexity to the creamy base of this low carb breakfast casserole.
- Cheddar cheese
- Cherry tomatoes – optional. They do add carbs to this dish (.7 g per cherry tomato to be exact).
How to Make Keto Breakfast Casserole:
- Add breakfast sausage to a large skillet over medium heat. Break the meat into small pieces while the sausage cooks. Once browned and no longer pink, remove to a paper towel-lined plate.
- Add vegetable oil. Once shimmering, add chopped onions, chopped bell peppers, and salt. Saute until soft, about 10 minutes.
- In a large bowl, whisk eggs, heavy cream, and tabasco.
- Stir in the shredded cheddar cheese, cooled sausage, cooled cooked veggies, and sliced cherry tomatoes.
- Pour into the prepared casserole dish.
- Bake in the oven for 35-40 minutes. You’ll know the casserole is done once the center is set and the edges begin to brown. Slice into 9 pieces, and enjoy!
💪 Meal Prepping Tips
Make this breakfast sausage casserole at the beginning of the week, slice it into pieces, and reheat each slice in the microwave for keto breakfast (lunch, snack, or dinner!).

- Cook sausage. Add breakfast sausage (1 pound) to a large skillet over medium heat. Break the meat into small pieces while the sausage cooks. Once browned and no longer pink, remove to a paper towel-lined plate.

Once shimmering, add chopped onions (1 cup), chopped bell peppers (1 cup), and salt (1 teaspoon). Saute until soft, about 10 minutes.

Lindsey's Tips
- Oil - opt for a mild-tasting oil with a high smoke point. My favorite is avocado oil. Skip olive oil and coconut oil here.
