Step-by-Step Instructions

Step 1: Prepare Your Foundation

First, grease a 9×13 inch baking dish with butter or cooking spray. Then, cook the breakfast sausage in a large skillet over medium heat until browned and crumbled. Next, drain excess fat and set aside to cool. Meanwhile, dice your vegetables into uniform pieces for even cooking.

Pro Tip: Cook sausage completely since it won’t cook further in the casserole.

Step 2: Create the Egg Mixture

Subsequently, crack eggs into a large mixing bowl and whisk vigorously. Then, add heavy cream, salt, pepper, and paprika. Furthermore, whisk until completely smooth and no streaks remain. This base creates the creamy texture that makes this Low Carb Egg Bake so satisfying.

Step 3: Layer Your Ingredients

Next, spread the cooked sausage evenly across the bottom of your prepared dish. Then, add diced bell peppers and onions over the sausage. Additionally, sprinkle half the cheese mixture over the vegetables. This layering technique distributes flavors throughout each bite.

Step 4: Combine and Chill

Now, pour the egg mixture slowly over the layered ingredients. Then, gently stir to combine without disturbing the layers too much. Subsequently, top with remaining cheese and cover tightly with plastic wrap. Finally, refrigerate overnight for flavors to meld.

Step 5: Bake to Perfection

The following morning, preheat your oven to 350°F (175°C). Then, remove plastic wrap and let the casserole sit at room temperature for 15 minutes. Next, bake for 40-45 minutes until the center is set and top is golden brown. Finally, let rest for 5 minutes before serving.

Testing Tip: Insert a knife in the center; it should come out clean when done.

Common Mistakes to Avoid

Preparation Errors:
Never skip the overnight resting period, as this develops flavors and improves texture. Additionally, avoid overmixing the egg mixture, which can create tough results. Furthermore, don’t forget to drain cooked sausage properly to prevent greasy casserole.

Baking Mistakes:
Resist the urge to increase oven temperature for faster cooking, which causes uneven results. Similarly, don’t open the oven door frequently during baking. Moreover, avoid underbaking, which leaves the center runny and unsafe.

Ingredient Issues:
Never use pre-shredded cheese exclusively, as anti-caking agents affect melting. Additionally, avoid adding vegetables with high water content without pre-cooking. Furthermore, don’t substitute egg whites entirely, as yolks provide necessary fat and flavor.

Storage Problems:
Avoid leaving the casserole at room temperature for more than 2 hours. Similarly, don’t freeze portions without proper wrapping, which causes freezer burn.

Storing Tips for the Recipe

Refrigerator Storage:
Cover leftover casserole tightly with aluminum foil or transfer to airtight containers. Then, refrigerate for up to 4 days maximum. Additionally, reheat individual portions in the microwave for 1-2 minutes or oven at 300°F for 10 minutes.

Freezer Storage:
First, cool the casserole completely before freezing. Next, wrap tightly in plastic wrap, then aluminum foil for double protection. Subsequently, freeze for up to 3 months. Finally, thaw overnight in refrigerator before reheating.

Make-Ahead Tips:
Prepare the casserole up to 2 days in advance before baking. Additionally, pre-cook and freeze sausage mixture for even faster assembly. Furthermore, pre-shred cheese and store in refrigerator for convenience.

Reheating Best Practices:
Reheat in 350°F oven for 15-20 minutes until heated through. Alternatively, microwave individual portions on 70% power to prevent overcooking. Moreover, add a splash of cream before reheating to restore moisture.
