Ingredients You’ll Need

Let’s talk about the simple ingredients that transform this breakfast bake into something extraordinary! Each element plays a key role—giving you a perfect blend of soft, cheesy, savory, and just the right touch of spice. Here’s what brings the Savory Overnight Sausage and Egg Breakfast Bake to life.

• White Bread (6-8 slices): Removing the crusts creates a super fluffy base that soaks up all the eggy goodness—use any sturdy white bread you love.
• Freshly Shredded Colby Jack or Cheddar Cheese (4 cups): Fresh shredding gives you meltier, more luscious results (and better flavor and texture than pre-shredded).
• Pork Sausage (12 ounces): Go for your favorite breakfast sausage—mild or spicy both work beautifully for adding depth and savory punch.
• Onion (1/4 medium, chopped): Offers subtle sweet flavor that balances the richness of the casserole.
• Red Bell Pepper (1/2, chopped): Brings color, juiciness, and a pop of brightness in every bite.
• Diced Green Chiles (one 4-ounce can): Adds gentle heat and layered flavor—don’t worry, it’s not too spicy!
• Large Eggs (6): The star that binds together all the ingredients for a custardy, satisfying bite.
• Milk (2 cups): Gives the casserole its creamy, light texture—whole milk is best if you have it.
• Kosher Salt (1 teaspoon): Enhances all the flavors in the dish without overwhelming.
• Paprika (1/2 teaspoon): Adds color and a hint of warmth—you can try smoked paprika for a twist!
• Dried Oregano (1/2 teaspoon): Rounds out the flavor with an herby note that’s not overpowering.
• Freshly Ground Black Pepper (1/2 teaspoon): Just enough to add a hint of spice and depth.
• Garlic Powder (1/4 teaspoon): Delivers subtle, savory flavor without raw garlic’s bite.
• Dry Mustard (1/4 teaspoon): This secret ingredient adds a gentle tang that wakes up the eggs and cheese.

Variations

One of the things I adore most about the Savory Overnight Sausage and Egg Breakfast Bake is how forgiving it is—swap, add, or remove ingredients to truly make it your own! Here are a few ideas to help inspire your next creation or suit any special diet or taste preference.

• Loaded Veggie Version: Add sautéed mushrooms, fresh spinach, or even zucchini for extra color, flavor, and nutrition.
• Cheese Lovers’ Twist: Try a blend of sharp cheddar, Monterey Jack, or pepper jack for a different cheese profile and a hint of heat.
• Meat-Free Morning: Swap sausage for plant-based crumbles or omit entirely—just amp up the veggies and seasonings.
• Salsa Flair: Replace the green chiles with your favorite chunky salsa, bringing zesty, tangy notes to the bake.

How to Make Savory Overnight Sausage and Egg Breakfast Bake

Step 1: Prepare the Bread Layer

Begin by removing the crusts from your bread slices—this step is what gives the casserole its classic, fluffy texture. Lightly butter or grease a 9×13-inch baking dish, then arrange the bread snugly across the bottom so there are no gaps. This becomes the pillowy base that soaks up all the tasty flavors!

Step 2: Cook the Sausage and Veggies

Brown the pork sausage in a skillet over medium heat, using your spoon to break it up into small bite-sized pieces. Once cooked, transfer the sausage to a plate and drain off any excess grease. In the same pan, toss in the chopped onion and red bell pepper—sauté until they’re just soft and fragrant, then stir in the diced green chiles for a lovely, savory boost.

Step 3: Layer Cheese, Sausage, and Veggies

Generously sprinkle your freshly shredded cheese over the bread, making sure there’s an even layer in every nook and cranny. Next, scatter the sausage evenly on top, followed by the sautéed onions, bell pepper, and green chiles. This layering ensures every bite gives you a delicious mix of flavors and textures.

Step 4: Whisk and Pour the Egg Mixture

In a large mixing bowl, crack in the eggs and whisk until blended. Add in the milk, salt, paprika, oregano, black pepper, garlic powder, and dry mustard. Whisk thoroughly so the spices get well incorporated. Slowly pour this custardy mixture all over the layered casserole, making sure everything gets nice and soaked.

Step 5: Chill Overnight

Cover the baking dish tightly and place it in the refrigerator for at least 6 hours—overnight is ideal! This gives all the flavors time to meld and the bread time to absorb the egg mixture, ensuring a perfectly creamy texture in the morning.

Step 6: Bake and Serve

In the morning, uncover your casserole and bake in a preheated 350°F oven for 50–60 minutes, or until the center is set and the edges are a gorgeous golden brown. Let it cool for about 15 minutes before serving—so it holds its shape and those melty, cheesy layers stay put when you cut into it. Dig in and enjoy!

How to Serve Savory Overnight Sausage and Egg Breakfast Bake

Garnishes

A sprinkle of fresh chopped parsley or sliced green onions over the baked casserole makes it pop with color and freshness. For a little extra tang, add a dollop of sour cream or a handful of diced tomatoes. You could even dash on some hot sauce for those who like a kick!

Side Dishes

Pair your Savory Overnight Sausage and Egg Breakfast Bake with a fresh fruit salad or a simple green salad for brightness and contrast. Buttery croissants, flaky biscuits, or even a side of crispy hash browns also round out this brunch feast to perfection.

Creative Ways to Present

Cut the casserole into neat squares and serve on a platter for a buffet, or plate individual portions with a swirl of salsa and colorful garnishes for a restaurant-style touch. For special occasions, bake in individual ramekins for a personalized spin—so fun for holiday breakfasts or brunch parties!

Make Ahead and Storage

Storing Leftovers

Place any leftover casserole into an airtight container—or cover your baking dish tightly with wrap. It’ll stay tender and tasty in the refrigerator for up to 3–4 days, ready to reheat for an easy breakfast or even a quick lunch.

Freezing

To freeze, assemble the Savory Overnight Sausage and Egg Breakfast Bake but don’t bake it. Cover tightly with plastic wrap, then a layer of foil. Freeze for up to 2–3 months. Thaw overnight in the fridge, and let it come to room temperature before baking as normal for best results.

Reheating

Warm leftover portions in the microwave for 1–2 minutes, or cover with foil and reheat in a 325°F oven until heated through. If reheating the entire casserole, a low oven helps keep it moist and evenly warm—just watch it so the cheese doesn’t get too brown!
