If gooey brunch casseroles and Homey morning meals make you smile, you'll want to try this Grilled Cheese Sausage and Egg Bake. Think melty American cheese, crisped sausage, creamy eggs, and thick slices of toasted Texas toast layered up. It’s the kind of warm, cheering breakfast you’ll want every weekend.
I started making this for holiday mornings and soon noticed how everyone ended up in the kitchen just to catch the smell while it baked. Now it’s the meal we’re all known for after sleepovers.
Hearty Ingredients
- American cheese: melts perfectly for that gooey, stringy bite. Go with deli sliced for smooth stacking
- Texas toast: thick and crunchy bread gives this big flavor. Try to grab bakery-fresh or slice your own
- Ground mustard: perks things up with a kick of tangy flavor
- Kosher salt and coarse black pepper: seasoning made simple to keep flavors in check
- Whole milk: makes everything super creamy and rich. Don’t skimp on the fat here
- Butter: gets that bread golden and adds an extra yum factor
- Large eggs: load this dish with protein and make it fluffy. Fresh ones work best
- Pork breakfast sausage: brings bold, savory flavor with just the right texture. Look for options without weird fillers
Easy-to-Follow Steps
- Brush Bread and Bake:
- Use melted butter to coat the bread slices up top and toss the dish in a 375 oven with foil on for 20 minutes. Take off the foil and bake 20 more until the surface is golden brown
- Add Your Top Toast:
- Lay those last bread slices on top to cap things off. That’s how you get that crispy sandwich feeling
- Mix Up and Pour Custard:
- Beat the last eight eggs with three-quarters cup of milk and ground mustard. Pour that mixture on, making sure it covers and soaks in everywhere
- Layer Sausage and Eggs:
- Toss cooked sausage over the cheesy bread then spread on your softly scrambled eggs. Pop another cheese slice over all of it for extra gooeyness
- Start the Base:
- Grease your 9x13 baking pan. Lay six slices of Texas toast in one even layer then top each with a cheese slice for mega cheese pull in each scoop
- Scramble Your Eggs:
- Put a spoonful of butter in the used skillet over low heat. Whisk together 10 eggs, a little milk, salt, and pepper then tip in and gently scramble, pulling them off the heat early so they stay soft
- Brown Your Sausage:
- Break up pork sausage in a skillet as it cooks on medium-high for about 5 minutes. When it’s browned and crumbly, drain on a paper towel-lined plate so the final dish doesn’t get oily

The best part’s seeing that bread get all toasty and crisp. My kid once asked for thirds at his birthday breakfast he loved it so much
Keeping It Fresh
Let leftovers cool fully first then cover tight and stick them in the fridge for up to four days. Warm slices in your oven or microwave when you want more. If you want to freeze, wrap pieces in foil first, freeze, then thaw overnight before popping them back in a hot oven
Swap Ideas
Switch to turkey or chicken sausage for something lighter. Try Monterey Jack or cheddar cheese if you want a different flavor or melt. Can’t find Texas toast? Use any thick sandwich loaf instead
How to Serve
Goes great with simple greens or fresh fruit for balance. Offer hot sauce or salsa for anyone who likes things spicy. Want a little sweet on the side? Put out some jam or maple syrup

Tradition and Inspiration
This classic bake takes the spirit of an American diner lunch and turns it into a cozy family breakfast. Born from grilled cheese nights and big weekend egg-and-sausage spreads, it’s a way to bring everyone together for slow mornings
Recipe FAQs
- → Is another type of bread okay?
Sure! Hearty breads like brioche, sourdough, or French bread will work, but Texas toast is best for soaking in the egg mixture.
- → What kind of cheese should I pick?
American cheese melts easily for a creamy texture, but cheddar, provolone, or Monterey Jack can offer different flavors.
- → Can it be prepped in advance?
Yep! Put everything together the night before, pop it in the fridge, and stick it in the oven in the morning for a quick meal.
- → Is there a way to swap the sausage?
Definitely! You can use bacon, turkey sausage, or even veggie sausage as a substitute to suit your preferences.
- → How can I avoid a soggy texture?
Stick to thicker bread and avoid over-soaking it. Baking uncovered at the end also helps with a crispy top.
- → What sides go well with it?
Fresh fruit, roasted potatoes, or a leafy green salad make for lovely sides to balance the dish.
