Step-by-Step Sleepin’ In Omelette Recipe
Ingredients
- 6 whole onion rolls
- 1 1/2 cups grated cheddar cheese
- 8 ounces cream cheese
- 1 1/2 sticks butter, sliced
- 10 whole eggs
- 2 cups whole milk
- 2 tablespoons chopped chives (or about 1 teaspoon dried chives)
- 1/2 teaspoon dry mustard
- 1/2 teaspoon salt
- Dash cayenne pepper (optional)
Instructions
- Prepare the Baking Dish: Generously butter a 9×13-inch dish for a nonstick, flavorful base.
- Tear and Layer Onion Rolls: Tear the rolls into bite-sized chunks and scatter evenly over the dish.
- Add Cheese and Cream Cheese: Sprinkle cheddar over bread pieces, then dot with chunks of cream cheese.
- Add Sliced Butter: Distribute sliced butter evenly over the layers.
- Whisk Egg Mixture: In a large bowl, whisk together eggs, milk, dry mustard, salt, cayenne (if using), and chives until well combined.
- Pour Egg Mixture: Slowly pour the mixture over the bread and cheese, ensuring it seeps into every crevice.
- Cover and Refrigerate: Cover dish tightly with foil and refrigerate overnight (up to 24 hours).
- Bake: Bake at 325°F, covered, for 45 minutes. Remove foil, increase heat to 350°F, and bake an additional 10–15 minutes.
- Let Stand and Serve: Allow the casserole to rest 5 minutes before serving for easier slicing.
Pro Tips for Sleepin’ In Omelette Success
- Ingredient Quality: Use fresh eggs, real butter, and good bread for best flavor.
- Butter Placement: For even richness, slice the butter thinly and distribute well. Some prefer mixing melted butter with milk, but the pat-on-top method is simpler and effective.
- Customizable Additions: Add cooked bacon, sautéed mushrooms, bell peppers, or spinach between layers for more flavor.
- Chive Choices: Either fresh or dried chives work, though fresh add brighter flavor.
- To Make Gluten Free: Substitute with gluten-free onion rolls or bread.
Why Overnight Casseroles Work
Overnight breakfast casseroles like the Sleepin’ In Omelette allow flavors to meld, the bread to soak up the custard, and busy hosts to enjoy more time with family in the morning. The dish also develops a rich, cohesive texture that’s hard to achieve with quick morning assembly. This convenience makes it ideal for holidays, brunch parties, and busy weekdays alike.
Serving Suggestions
- Classic Brunch Combo: Serve with fruit salad, fresh squeezed juice, and cinnamon rolls for a full spread.
- Holiday Breakfast: Pair with hash browns or roasted potatoes.
- Light Lunch: Serve with arugula salad and vinaigrette.
- Beverage Ideas: Mimosas, coffee, or herbal teas complement this rich casserole perfectly.
Frequently Asked Questions (FAQs)
What others are reading
Q: Can I prepare Sleepin’ In Omelette two days in advance?
A: It’s best made no more than 24 hours in advance to maintain bread and casserole texture. Longer refrigeration can cause sogginess.
Q: What kind of onion rolls should I use?
A: Any soft onion rolls from your grocery bakery or bread aisle will work; avoid crusty styles for the best texture.

A: Cream cheese provides creamy pockets, but you can swap with goat cheese, ricotta, or omit for a lighter casserole.
Q: Is it necessary to use dry mustard?
A: Dry mustard boosts savory complexity, but you may substitute with Dijon mustard or omit if preferred.

Expert Notes from the Pioneer Kitchen
The Pioneer Woman’s approach emphasizes simplicity and warmth in every step. Buttering the dish generously not only keeps sticking at bay but creates a crispy bottom layer. Dotting cream cheese unevenly gives delightful tangy bites, and the combination of cheddar with onion rolls means every mouthful is full of savory goodness. Her trick of patting butter on top, rather than mixing it cold with milk, ensures an evenly rich finish without unwanted separation.
Recipe Recap: Sleepin’ In Omelette
- Assemble layers in a buttered casserole dish the night before.
- Cover and let flavors mingle overnight in the fridge.
- Bake covered, then uncovered, until set with a golden top.
- Rest before slicing and serve hot.
Troubleshooting & Tips
- Casserole too soft? Bake slightly longer, uncovered, for a firmer top.
- Butter pools? Use 1 1/2 sticks max; slice thin, or mix with milk if preferred.
- Dry edges? Pour egg mixture slowly, ensuring full coverage and soak.
- No onion rolls? Use challah, brioche, or lightly toasted sandwich buns with chopped scallion instead.
