Equipment

<ul class="equipment-main-list"><li class="equipment-single-item">23cm x 33cm (9x13-inch) baking dish</li><li class="equipment-single-item">Large non-stick frying pan</li><li class="equipment-single-item">Mixing bowls</li><li class="equipment-single-item">Whisk</li></ul>

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C (350°F). Generously grease a 23x33cm baking dish with butter or olive oil to prevent sticking, as eggs can be particularly stubborn without proper greasing.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Heat a large non-stick frying pan over medium-high heat. Add the ground sausage, breaking it up with a wooden spoon as it cooks. Brown the sausage for about 5-7 minutes until it's no longer pink and has developed some caramelized edges, which adds significant flavor to your casserole.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the diced onion and bell pepper to the pan with the sausage. Cook for another 4-5 minutes until the vegetables have softened. Add the minced garlic and cook for 30 seconds until fragrant, being careful not to burn it as this will create bitterness.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Remove the sausage mixture from heat and let it cool slightly for about 5 minutes. This cooling step is important as adding hot sausage directly to eggs can cause them to start cooking prematurely, resulting in an uneven texture.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>In a large bowl, whisk together the eggs and heavy cream until well combined. The cream adds fat which is essential for a keto diet, while also creating a silkier, more custard-like texture in the final casserole. Whisk in the salt, black pepper, dried oregano, and cayenne pepper if using.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Spread the cooled sausage mixture evenly across the bottom of your greased baking dish. Sprinkle half of the grated cheddar cheese over the sausage layer. The cheese will melt between the layers, creating pockets of delicious cheesy goodness.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Distribute the small pieces of cream cheese evenly across the mixture. The cream cheese won't fully incorporate, instead creating rich, creamy pockets throughout the casserole as it bakes.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Pour the egg mixture carefully over the sausage and cheese layers. Give the dish a gentle shake to help the egg mixture settle between the ingredients. Sprinkle the remaining cheddar cheese on top, which will create a beautiful golden crust.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Bake uncovered for 35-40 minutes, or until the center is set and no longer jiggly, and the top is golden brown. A knife inserted in the center should come out clean, though a few moist crumbs are fine. If the top starts to brown too quickly before the center is set, loosely cover with aluminum foil.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Remove from the oven and allow to rest for 5-10 minutes before cutting. This resting period is crucial as it allows the eggs to fully set and makes cutting cleaner slices much easier. Sprinkle with chopped chives or green onions just before serving for a fresh flavor contrast and beautiful color.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Serve warm, or let cool completely before refrigerating. This casserole keeps beautifully in the refrigerator for up to 4 days and can be reheated in the oven at 160°C (325°F) for 10-15 minutes or in the microwave for individual portions. You can also freeze portioned slices for up to 2 months in airtight containers.</li></ol>

This keto-friendly casserole uses breakfast sausage, onion, red bell pepper, garlic, eggs, heavy cream, cheddar and cream cheese, plus seasonings like salt, pepper, oregano, and optional cayenne. Fresh chives or green onions garnish the dish for added flavour.

How to cook Keto Sausage & Egg Casserole at home?

Learn how to cook Keto Sausage & Egg Casserole by browning sausage with vegetables, layering it with cheese in a baking dish, pouring over a seasoned egg and cream mixture, then baking until golden and set. The process creates a protein-rich, low-carb breakfast that can be prepared ahead for busy mornings.

Can I prepare this breakfast casserole the night before baking?

Absolutely! You can assemble the entire casserole the night before, cover it with cling film, and refrigerate overnight. Simply remove from the fridge about 30 minutes before baking to take the chill off, then bake as directed, perhaps adding 5-10 minutes to the cooking time.

What vegetables can I add to my low-carb egg casserole without increasing the carb count?

Great keto-friendly vegetable additions include spinach, kale, mushrooms, courgette, asparagus, and broccoli florets. Just ensure they're well-drained to prevent a watery casserole. These add nutrients and fibre while keeping carbs low—aim for about 1-2 cups total to maintain the egg-to-veg ratio.

Why is my egg casserole watery and how can I prevent this?

Watery casseroles typically result from vegetables releasing moisture during cooking. Prevent this by pre-cooking and draining vegetables thoroughly, using room temperature ingredients, and allowing sausage to cool before adding. For extra insurance, a tablespoon of coconut flour mixed into the egg mixture can help absorb excess moisture.
