How to Make This Low Carb Sausage Egg Casserole
Start by cooking the pork sausage in a skillet over medium-high heat. Drain the excess grease thoroughly so your casserole doesn’t turn out oily.
In a large bowl, whisk your eggs, almond milk, salt, mustard, sage, and pepper until uniformly combined. Add the cubed bread, shredded cheese, and cooked sausage. Stir everything gently so the bread is well-coated.

Pour the mixture into a greased baking dish and refrigerate for at least 8 hours. Let the dish sit on the counter for 30 minutes before baking to take the chill off.
Bake at 350°F until the top is puffed and golden brown. Let it rest for 10 minutes before slicing so the slices hold their shape.
Tips, Swaps, & Storage
- The Bread: Use a sturdy low-carb bread. If you want extra sides, this pairs well with a warm slice of cheesy skillet bread.
- Add Greens: Balance your plate by serving this alongside some roasted lemon garlic asparagus.
- Need a sweet option? If you prefer alternating savory and sweet breakfasts during the week, prep some vanilla chia pudding for the next day.
- Storage: Keep leftovers in an airtight container in the fridge for up to 4 days. Reheat individual slices in the microwave for 60 seconds.
- Don’t worry if the top looks excessively puffy when it comes out of the oven. It will settle as it rests on the counter.
Quick FAQs
Can I skip the overnight chill?
You can, but I don’t recommend it. The bread needs time to absorb the liquid so it doesn’t just float to the top during baking.
What milk alternative works best?
Unsweetened almond milk keeps the carb count low. Unsweetened coconut milk or even heavy cream also work well if you prefer a richer texture.

Description
A delicious and satisfying make-ahead casserole featuring savory sausage, eggs, cheese, and low-carb bread cubes. Perfect for meal prep, this dish is chilled overnight, allowing the flavors to meld beautifully before baking, offering a convenient low-carbohydrate breakfast or brunch option.
Ingredients
- 12 ounces bulk pork sausage
- 6 large eggs
- 1 ¾ cups unsweetened almond milk (or other low-carb milk alternative)
- ¾ teaspoon salt
- ¾ teaspoon ground mustard
- ½ teaspoon dried sage
- ½ teaspoon black pepper
- 5 slices low-carb bread (cut into ½-inch cubes (approx. 4 cups cubed))
- ¾ cup shredded sharp Cheddar cheese
- Cooking spray or butter for greasing the dish
Instructions
- Prepare Dish: Lightly grease an 8×8 inch square baking dish with cooking spray or softened butter.
- Cook Sausage: In a medium skillet over medium-high heat, cook the pork sausage, crumbling it with a spoon, until browned and cooked through (about 8-10 minutes). Drain off any excess grease thoroughly.
- Combine Wet Ingredients: In a large bowl, whisk together the eggs, unsweetened almond milk, salt, ground mustard, dried sage, and black pepper until uniformly combined.
- Assemble Casserole: Add the cubed low-carb bread, shredded Cheddar cheese, and the cooked, drained sausage to the egg mixture. Gently stir to ensure the bread is well-coated.
- Chill: Pour the mixture evenly into the prepared baking dish. Cover the dish securely (e.g., with plastic wrap or a fitted lid) and refrigerate for at least 8 hours, or overnight. This step is crucial for the bread to absorb the egg mixture.
- Preheat & Rest: Remove the casserole from the refrigerator 30 minutes prior to baking to allow it to come closer to room temperature. Preheat your oven to 350°F (175°C).
- Bake: Uncover the dish. Bake in the preheated oven for 40 to 50 minutes, or until the top is golden brown, the casserole is puffed, and a knife inserted into the center comes out clean.
- Serve: Let the casserole rest for 5-10 minutes before slicing into 6 portions and serving warm.
