Overnight Sausage Egg Casserole Ingredients
This delicious casserole is fueled by simple yet powerful ingredients!
For the Casserole
• Medium Pork Sausage – Provides flavor and protein; choose mild or medium depending on your heat preference.
• Onion – Adds sweetness and depth; shallots or green onions can substitute for a milder taste.
• Eggs – Create the custardy base that binds the casserole; a mix of whole eggs and egg whites offers a lower-cholesterol option.
• Whole Milk – Contributes creaminess and moisture; you can opt for 2% milk for a lighter version.
• Cheddar Cheese – Enhances flavor and texture; always go for a block of cheese to shred for the best taste.
• Dry Mustard – Adds subtle warmth; feel free to adjust the quantity based on your preference.
• Salt and Pepper – Basic seasonings essential for enhancing flavors; approximately ½ tsp salt and ¼ tsp pepper works well.
• Bread (4 cups) – Essential for texture and structure; sprouted grain, whole grain, or brioche are excellent choices; removing crusts helps the bread soak better.
This Overnight Sausage Egg Casserole is not only easy to make but is also an ideal protein boost to kickstart your day!
Step‑by‑Step Instructions for High-Protein Overnight Sausage Egg Casserole
Step 1: Cook Sausage & Onion
In a large skillet over medium heat, add the medium pork sausage, breaking it up into small pieces as it browns, about 5-7 minutes. Once the sausage is cooked through and no longer pink, add the chopped onion and sauté until softened and translucent, about 3-4 minutes. Carefully drain any excess fat and allow the mixture to cool slightly while you prepare the next steps.
Step 2: Prepare Egg Mixture
In a large mixing bowl, whisk together 8 large eggs, 2 cups of whole milk, and 2 cups of shredded cheddar cheese until smooth and well combined. Stir in 1 tablespoon of dry mustard, along with ½ teaspoon of salt and ¼ teaspoon of pepper for flavor. Once the egg mixture is uniform, gently fold in the cooled sausage and onion mixture to create a hearty filling for your casserole.
Step 3: Assemble Casserole
Lightly spray a 9×13-inch baking dish with olive oil to prevent sticking. Evenly distribute 4 cups of bread cubes (fresh or stale) in the prepared dish so that they form a foundation. Next, pour the egg and sausage mixture generously over the bread, ensuring the cubes are well soaked. Press down slightly to help the bread absorb the flavorful liquid.
Step 4: Refrigerate Overnight
Cover the dish tightly with plastic wrap or aluminum foil, making sure it’s sealed to prevent any odors from the fridge from affecting the casserole. Place the assembled High-Protein Overnight Sausage Egg Casserole in the refrigerator and let it sit overnight, allowing the bread to soak and the flavors to meld for optimal results.
Step 5: Bake
Preheat your oven to 350°F (175°C) about 30 minutes before baking. Once heated, remove the cover from your casserole and bake it uncovered for 50 minutes to 1 hour, or until the center is set and the top is golden brown, bubbling just slightly. To check if it’s done, look for a firm texture that does not jiggle in the middle. Let it rest for about 10 minutes before slicing.
