Ingredients You’ll Need

Here’s what you’ll need to make Low-Carb Sausage, Egg & Cheese Breakfast Casserole:

For the Casserole:

• 1 pound breakfast sausage (mild, hot, or turkey sausage, depending on preference)
• 8 large eggs
• ½ cup heavy cream or unsweetened almond milk
• 1 teaspoon salt

Step-by-Step Instructions

Step 1: Preheat Your Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or similar-sized casserole dish with cooking spray or olive oil.

Step 2: Cook the Sausage and Vegetables

1. In a large skillet over medium heat, cook the sausage until browned and crumbled, about 6–8 minutes.
2. Add the diced bell peppers and onions to the skillet and sauté for an additional 3–4 minutes, until the vegetables are softened. If using spinach or other greens, stir them in during the last minute of cooking to wilt.
3. Remove the mixture from heat and spread it evenly across the bottom of the prepared baking dish.

Step 3: Prepare the Egg Mixture

1. In a large mixing bowl, whisk together the eggs, heavy cream (or almond milk), salt, and pepper until well combined.
2. Pour the egg mixture evenly over the sausage and vegetable layer in the baking dish.

Step 4: Add the Cheese

Sprinkle the shredded cheddar cheese evenly over the top of the casserole.

Step 5: Bake

Bake the casserole in the preheated oven for 25–30 minutes, or until the eggs are set and the top is golden brown. To check for doneness, insert a knife into the center—if it comes out clean, the casserole is ready.

Step 6: Cool and Serve

Let the casserole cool for 5–10 minutes before slicing. Serve warm with optional toppings like avocado slices, salsa, or fresh herbs.

Tips for the Best Breakfast Casserole

1. Use Fresh Ingredients : Freshly shredded cheese melts better than pre-shredded cheese, which often contains anti-caking agents that can affect texture.
2. Don’t Overmix the Eggs : Whisk the eggs just until combined to avoid making the casserole dense.
3. Add Extra Veggies : Stir in zucchini, spinach, or mushrooms for added nutrition and flavor.
4. Experiment with Cheese : Try using pepper jack cheese for a spicy kick or mozzarella for a gooey, melty texture.
5. Double the Recipe : This casserole reheats well, so consider doubling the recipe for leftovers or larger gatherings.

Variations to Try

While the classic version is divine, here are some creative twists to try:

1. Spicy Version : Use hot sausage and add diced jalapeños or red pepper flakes for an extra kick.
2. Cheese Lovers’ Casserole : Use a combination of cheddar, Monterey Jack, and Parmesan for an ultra-cheesy experience.
3. Turkey or Chicken Option : Substitute pork sausage with turkey or chicken sausage for a leaner alternative.
4. Vegetarian Version : Replace the sausage with sautéed mushrooms, zucchini, or a plant-based sausage substitute.
5. Breakfast Burrito Style : Top with salsa, sour cream, and guacamole for a burrito-inspired twist.
