Ingredients You’ll Need
The beauty of the Mississippi Sin Breakfast Casserole Recipe lies in its simplicity. Each ingredient is chosen to layer flavor and texture seamlessly, making the preparation straightforward yet incredibly rewarding.
- Refrigerated crescent rolls (8 oz): This forms the buttery, flaky base that holds everything together.

- Large eggs (6): They provide the rich, fluffy custard that binds the filling.
- Milk (½ cup): Keeps the egg mixture silky and tender.
- Cream cheese (2 Tbsp, room temperature): Boosts creaminess and adds a subtle tang.
- Sour cream (2 Tbsp): Enhances the moist texture and depth of flavor.
- Hot sauce (½ tsp): Adds a gentle kick that brightens the casserole.

How to Make Mississippi Sin Breakfast Casserole Recipe
Step 1: Prepare Your Pan and Crust
Start by preheating your oven to 350ºF and lightly spraying a 9x13x2-inch baking pan to ensure your casserole won’t stick. Then, unroll the refrigerated crescent rolls and press them into the bottom and sides of the pan, carefully sealing any seams. This step creates a sturdy, buttery crust that will crisp nicely while baking, forming the perfect foundation for the delicious filling.
Step 2: Layer the Filling
Next, sprinkle the diced ham evenly over the crescent roll crust. Add the chopped green onions for a fresh burst of color and subtle sharpness. Finally, pile on the shredded cheddar cheese, which will melt throughout the casserole, creating pockets of gooey, cheesy goodness that everyone will love.
Step 3: Make the Egg Mixture
In a large bowl, whisk together the eggs, milk, cream cheese, sour cream, Worcestershire sauce, hot sauce, garlic powder, salt, and pepper until smooth and well combined. The cream cheese and sour cream might seem like an unexpected twist, but they make the custard rich and velvety, elevating this casserole beyond your typical breakfast bake.
Step 4: Combine and Bake
Pour the egg mixture evenly over your layered ham and cheese in the pan. Pop the casserole into the oven and bake for 40 to 50 minutes, or until the center is set and the edges are golden. You can test doneness by gently shaking the pan—the center should not jiggle but be firm to the touch. This baking process melds all the flavors together into a hearty, crave-worthy dish.
How to Serve Mississippi Sin Breakfast Casserole Recipe

Garnishes
Once out of the oven, let your casserole cool just a bit, then garnish with fresh green onion slices or a sprinkle of chopped fresh parsley. These simple touches add a fresh aroma and visual contrast that bring the dish alive on the plate. For an extra pop of flavor, a light drizzle of your favorite hot sauce can kick things up a notch.
Side Dishes
The Mississippi Sin Breakfast Casserole Recipe is a satisfying main event, but it pairs beautifully with light, complementary sides. Think fresh fruit salad for a burst of sweetness or a crisp green salad with a tangy vinaigrette to balance the casserole’s richness. If you want something to sip, freshly brewed coffee or a citrusy mimosa will round out your breakfast perfectly.
Creative Ways to Present
If you’re serving guests or want to make breakfast extra special, consider slicing the casserole into individual portions and topping each with a dollop of sour cream or a little avocado mash. You can even wrap slices in warm tortillas for a breakfast casserole “burrito” style treat. The fun part about this recipe is how flexible it is to presentation, keeping things fresh and inviting each time you serve it.
Make Ahead and Storage
Storing Leftovers
Any leftovers can be covered tightly and stored in the refrigerator for up to 3 days. The casserole actually develops even better flavor after sitting, making reheated slices a fantastic second-day breakfast or brunch option.
Freezing
You can freeze this casserole either before baking or after it has cooked. For unbaked casseroles, assemble everything in a freezer-safe dish, cover tightly with foil, and freeze for up to 3 months. Bake it directly from frozen, just adding extra time to the baking process. If freezing after baking, let it cool completely, wrap well, and freeze slices individually to reheat as needed.
Reheating
Reheat leftovers in the oven at 350ºF for 15-20 minutes or until warmed through. To keep the crust crisp, avoid microwaving if possible. For a quick fix, a toaster oven works wonderfully and preserves that freshly baked texture.
FAQs
Can I use other meats instead of ham in this casserole?
Absolutely! While diced ham is traditional and adds a lovely saltiness, you can swap in cooked sausage, bacon, or even cooked chicken to suit your preferences or what’s on hand.
What if I don’t have crescent rolls? Can I use another crust?
Yes, a flaky pie crust or even refrigerated biscuit dough can work as a substitute. Just press it into the pan the same way and keep an eye on baking time, as it may vary slightly.
Is this casserole gluten-free?
Unfortunately, the traditional recipe isn’t gluten-free due to the crescent rolls. However, you can try gluten-free crescent roll dough or a gluten-free pastry crust to make it safe for gluten-sensitive eaters.
Can I prepare this casserole the night before?
Definitely! You can assemble the casserole the night before, cover it tightly, and refrigerate. In the morning, bake it as directed, adding a few extra minutes if baking straight from cold.
How spicy is the hot sauce in this recipe?
The hot sauce adds just a subtle warmth to complement the savory flavors without overpowering the dish. Feel free to adjust the amount to match your heat preference or leave it out altogether for a milder casserole.
