Ingredients for Grilled Cheese Sausage & Egg Breakfast Casserole

• Large eggs: Essential for binding everything together, eggs add richness and protein to the casserole.
• Whole milk: This adds creaminess to the egg mixture. You can substitute with almond or oat milk for a dairy-free version.
• Heavy cream: For that extra indulgence, heavy cream makes the casserole rich and velvety.
• Dijon mustard: A touch of tanginess that elevates the flavor profile. You can swap it for yellow mustard if that’s what you have on hand.
• Garlic powder: This adds a subtle depth of flavor. Fresh garlic can be used if you prefer a stronger taste.
• Onion powder: A great way to infuse onion flavor without the texture. Fresh onions are also a fantastic addition.
• Salt and black pepper: Essential seasonings that enhance all the flavors in the casserole.
• Sandwich bread: The base of the casserole, providing structure. Use any bread you like—white, whole grain, or even gluten-free.
• Shredded cheddar cheese: A classic choice that melts beautifully and adds a sharp flavor. Feel free to mix it up with your favorite cheese.
• Shredded mozzarella cheese: This cheese brings a gooey texture that complements the cheddar perfectly.
• Cream cheese: Cut into small pieces, it adds creaminess and a delightful tang.
• Onion: Finely diced, it adds sweetness and depth. You can use shallots or green onions for a different flavor.
• Butter: For greasing the baking dish, ensuring nothing sticks. Olive oil can be a healthier alternative.
• Fresh parsley: Chopped for garnish, it adds a pop of color and freshness to the finished dish.

How to Make Grilled Cheese Sausage & Egg Breakfast Casserole

Creating this Grilled Cheese Sausage & Egg Breakfast Casserole is a straightforward process that will have your kitchen smelling heavenly. Follow these simple steps, and you’ll be on your way to a delicious breakfast that everyone will love!

Step 1: Preheat the Oven

Start by preheating your oven to 180°C (350°F). Preheating is crucial because it ensures even cooking. If you skip this step, your casserole might not set properly, leaving you with a soggy mess instead of a fluffy delight.

Step 2: Cook the Sausage and Onion

In a large skillet, cook the breakfast sausage over medium heat for about 6–8 minutes. Break it into small pieces as it cooks. Once it’s browned, add the finely diced onion and cook for another 2–3 minutes until the onion is soft. Don’t forget to drain any excess grease; this keeps your casserole from becoming too oily.

Step 3: Prepare the Egg Mixture

In a large bowl, whisk together the eggs, whole milk, heavy cream, Dijon mustard, garlic powder, onion powder, salt, and black pepper. Mix until everything is smooth and well combined. This egg mixture is the glue that holds your casserole together, so make sure it’s blended nicely!

Step 4: Assemble the Casserole

Grease a 23 × 33 cm baking dish with butter. Spread half of the bread cubes across the bottom. Then, layer half of the cooked sausage and onion mixture, followed by half of the cheddar, mozzarella, and cream cheese. Repeat these layers with the remaining ingredients. Finally, pour the egg mixture evenly over everything, ensuring all the bread is soaked.

Step 5: Refrigerate Before Baking

Cover the casserole and refrigerate it for at least 30 minutes, or even overnight if you prefer. This resting time allows the bread to absorb the egg mixture, resulting in a more flavorful and cohesive dish. If you’re in a hurry, let it sit for about 10 minutes before baking.

Step 6: Bake the Casserole

Cover the casserole loosely with aluminum foil and bake for 30 minutes. After that, remove the foil and continue baking for another 10–20 minutes. You’ll know it’s done when the center is set and the cheese is golden and bubbling. Keep an eye on it to avoid overcooking!

Step 7: Serve and Enjoy

Once baked, let the casserole rest for 5–10 minutes. This helps it firm up a bit, making it easier to slice. Sprinkle with fresh parsley for a pop of color, then slice and serve warm. Enjoy the smiles on everyone’s faces as they dig into this hearty breakfast!

Tips for Success

• Use a mix of sharp cheddar and mozzarella for the best flavor and texture.
• Let the casserole sit in the fridge overnight for maximum flavor absorption.
• For a crispy top, uncover the casserole during the last 15 minutes of baking.
• Feel free to add your favorite veggies or meats for a personalized touch.
• Always check for doneness by inserting a knife in the center; it should come out clean.

Equipment Needed

• Baking dish: A 23 × 33 cm dish is ideal, but any similar-sized dish will work.
• Large skillet: For cooking the sausage and onions; a non-stick skillet makes cleanup easier.
• Mixing bowl: A large bowl for whisking the egg mixture.
• Whisk: Essential for blending the eggs and other ingredients smoothly.
• Aluminum foil: To cover the casserole while baking.

Variations

• Vegetarian Option: Swap the sausage for sautéed mushrooms, spinach, or bell peppers for a delicious meatless version.
• Spicy Kick: Add diced jalapeños or a sprinkle of red pepper flakes to the egg mixture for some heat.
• Herb Infusion: Mix in fresh herbs like basil, thyme, or chives for an aromatic twist.
• Cheese Lovers: Experiment with different cheeses like pepper jack, gouda, or feta for unique flavors.
• Gluten-Free: Use gluten-free bread to make this casserole suitable for those with dietary restrictions.

Serving Suggestions

• Fresh Fruit: Serve with a side of mixed berries or sliced oranges for a refreshing contrast.
• Coffee or Tea: Pair with a hot cup of coffee or herbal tea to complement the flavors.
• Presentation: Garnish with extra parsley or chives for a pop of color on the plate.
• Hot Sauce: Offer a selection of hot sauces for those who enjoy a spicy kick.
