How to Make Make Ahead Waffle Casserole

Step 1: Cook the Sausage

• Start by cooking the keto breakfast sausage in a large skillet over medium heat. Break it into small crumbles as it cooks and ensure it’s fully browned. Remove from heat and set aside.

Step 2: Prepare the Egg Mixture

• In a large mixing bowl, whisk together the eggs, heavy cream, dry mustard, pink salt, and cracked black pepper until fully combined.

Step 3: Toast the Waffles

• Toast the keto toaster waffles lightly until crisp. Cut each waffle into quarters to make layering easier.

Step 4: Assemble the Casserole

1. Grease a 9×13-inch baking dish with cooking spray or butter.
2. Arrange a layer of toasted waffle quarters on the bottom of the dish.
3. Spread half of the cooked sausage evenly over the waffles.
4. Sprinkle a generous layer of shredded cheddar cheese over the sausage.
5. Repeat the layering process—waffles, sausage, cheese—until all ingredients are used, ending with a layer of cheese on top.

Step 5: Add the Egg Mixture

• Slowly pour the egg mixture evenly over the entire casserole. Use a spatula to press down gently, ensuring the liquid soaks into the waffles and layers.

Step 6: Chill Overnight

• Cover the casserole tightly with plastic wrap or aluminum foil and refrigerate for at least 6 hours or overnight. This allows the flavors to meld and the waffles to absorb the custard.

Step 7: Bake the Casserole

1. Preheat your oven to 375°F (190°C).
2. Remove the casserole from the fridge and let it sit at room temperature for 10–15 minutes.
3. Bake uncovered for 40–45 minutes, or until the top is golden brown and the eggs are fully set.

Step 8: Serve and Enjoy

• Let the casserole cool for 5 minutes before slicing. Drizzle with keto syrup and serve warm.

Tips for the Best Waffle Casserole

1. Use Crisp Waffles: Lightly toasting the waffles ensures they hold up during baking.
2. Don’t Skip the Chill Time: Refrigerating overnight helps the flavors meld together and prevents a soggy texture.
3. Customize the Cheese: Feel free to use your favorite cheese blend for added flavor.
4. Add Veggies: Incorporate diced bell peppers, spinach, or mushrooms for extra nutrients.
5. Serve Fresh: The casserole tastes best when served warm, straight from the oven.

Flavor Variations and Additions

• Veggie Lover’s Casserole: Add sautéed onions, bell peppers, or zucchini to the sausage layer.
• Tex-Mex Twist: Swap the cheddar for Pepper Jack cheese and add diced jalapeños for a spicy kick.
• Sweet and Savory: Add a sprinkle of cinnamon to the egg mixture for a hint of sweetness.
• Herby Delight: Incorporate fresh herbs like thyme, parsley, or chives into the egg mixture.
