Step-by-Step Instructions
-
Step 1: Prepare the Baking Dish and English Muffins
Lightly grease a 9×13-inch baking dish with the softened butter. Spread the cubed English muffins evenly over the bottom of the prepared dish. This forms the delicious, sturdy base for your casserole.
Small tip: For extra flavor and texture, you can lightly toast the English muffin cubes in a dry pan or oven for a few minutes before adding them to the dish. This prevents them from becoming too soggy.
-
Step 2: Layer the Ham and Cheese
Scatter the diced ham evenly over the English muffins. Next, sprinkle both the Gruyere and cheddar cheeses over the ham layer. Finish by scattering the 2 tablespoons of chopped fresh chives over the cheese.
Small tip: Using a mix of cheeses adds depth of flavor. Gruyere melts beautifully and offers a nutty note, while sharp cheddar provides a classic, tangy taste.
-
Step 3: Whisk the Egg Custard
In a large bowl, whisk together the eggs, whole milk, heavy cream, Dijon mustard, salt, pepper, and nutmeg until well combined and smooth. Make sure there are no lumps of egg yolk remaining.
Small tip: The Dijon mustard is a secret ingredient here; it adds a subtle tang that brightens the rich egg custard without being overpowering.
-
Step 4: Pour Custard and Chill Overnight
Carefully pour the egg custard mixture evenly over the layers in the baking dish. Gently press down on the English muffins with a spatula to ensure they are fully submerged and soaking up the liquid. Cover the dish tightly with plastic wrap.
Refrigerate for at least 8 hours, or preferably overnight. This chilling time is crucial for the muffins to absorb the custard, creating a tender, cohesive casserole.
-
Step 5: Bake the Casserole
The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and uncover it. Bake for 45-55 minutes, or until the casserole is golden brown, puffed, and a knife inserted into the center comes out clean.
Small tip: If the top starts to brown too quickly, you can loosely tent the casserole with aluminum foil for the last 10-15 minutes of baking.
-
Step 6: Prepare the Quick Hollandaise
While the casserole bakes during the last 10-15 minutes, prepare the hollandaise. In a blender, combine the egg yolks, lemon juice, salt, and cayenne pepper (if using). Blend on high for about 10 seconds.
With the blender running on low speed, slowly and steadily pour the hot melted butter into the egg mixture. Blend until the sauce is thick, creamy, and emulsified, about 30-60 seconds. Taste and adjust seasoning if needed.
Small tip: Make sure your butter is hot, not just melted, as the heat helps to cook the egg yolks slightly and create a stable emulsion. Pour it in a very thin, steady stream for the best results.
-
Step 7: Serve and Garnish
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the casserole to set slightly. Cut into squares and transfer to plates.
Drizzle each serving generously with the warm quick hollandaise sauce. Garnish with extra fresh chives, chopped parsley, or a sprinkle of smoked paprika for a beautiful finish. Enjoy your gourmet breakfast!
Tips & Variations
- Gluten-Free Option: Simply swap out the regular English muffins for your favorite gluten-free brand. The rest of the recipe is naturally gluten-free.
- Vegetarian Option: Omit the ham entirely. You can replace it with sautéed mushrooms, spinach, or roasted red peppers for delicious savory additions.
- Add More Vegetables or Protein: Feel free to customize! Sautéed spinach, asparagus pieces, bell peppers, or caramelized onions would be wonderful. For extra protein, cooked crumbled sausage or bacon can be added with the ham.
- Spicy Version: For a kick, add a pinch of red pepper flakes to the egg custard. You can also increase the cayenne pepper in the hollandaise sauce or add a dash of your favorite hot sauce.
- Cheese Lovers Dream: Experiment with different cheese combinations. Provolone, Monterey Jack, or even a smoked Gouda would offer unique flavor profiles.
- Herbaceous Twist: Incorporate other fresh herbs like fresh thyme, oregano, or a touch of rosemary into the egg custard for an aromatic variation.

Health Benefits
This Overnight Eggs Benedict Casserole, while indulgent, also offers several health benefits from its key ingredients. Eggs, a star component, are a powerhouse of nutrition. They are an excellent source of high-quality protein, essential for muscle repair and growth. Eggs also provide vital vitamins like B12 and D, and choline, which is crucial for brain health and metabolism.
The ham, especially if lean, contributes more protein and B vitamins such as niacin and thiamine, which are important for energy production. It also provides iron, vital for healthy red blood cells.
Cheese, used generously in this recipe, is a fantastic source of calcium, which is fundamental for strong bones and teeth. It also provides protein and other essential minerals like phosphorus.
If you opt for whole-grain English muffins, you’ll be adding valuable dietary fiber to your meal. Fiber aids in digestion, helps maintain healthy blood sugar levels, and can contribute to a feeling of fullness, which is great for managing appetite.
Incorporating fresh chives not only adds flavor but also a touch of vitamins K and C, and antioxidants. Adding extra vegetables like spinach or asparagus (as suggested in variations) would further boost the vitamin, mineral, and fiber content, making it an even more nutrient-dense meal.
Serving Suggestions
- Serve with a vibrant fresh fruit salad for a refreshing contrast to the rich casserole. Think berries, melon, and grapes!
- Pair with a crisp green salad tossed in a light vinaigrette to balance the meal, especially if serving for brunch.
- Offer alongside mimosas or freshly squeezed orange juice for an ultimate celebratory breakfast or brunch experience.
- This casserole is hearty enough to be the star of your meal. It works perfectly as a main dish for a special occasion or a leisurely weekend breakfast.
- For meal prep, you can dice the ham and shred the cheeses a day or two in advance. The casserole itself is designed for overnight prep, making your morning easy.
Storage Tips
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. While it can be frozen, the texture might change slightly upon thawing and reheating, becoming a bit softer. To freeze, wrap individual portions tightly in plastic wrap and then aluminum foil; it will keep for up to 1 month. To reheat, cover portions with foil and bake in a preheated oven at 300°F (150°C) until warmed through, or microwave individual servings until hot. The hollandaise sauce is best made fresh and does not store or reheat well.
