Creamy Overnight Eggs Benedict Casserole with Homemade Hollandaise Recipe

“You really think you can make hollandaise without a double boiler?” my friend asked, eyeing the whisk in my hand with a smirk. Honestly, I was skeptical myself — hollandaise has always seemed like one of those fancy sauces you only order at brunch spots, right? But after this creamy overnight Eggs Benedict casserole came together in my kitchen (after a few laughs and a little patience), I realized that making your own hollandaise and baking the whole thing as an easy casserole is a total game-changer.

It all started on a chaotic Sunday morning when I had promised to bring brunch to a last-minute gathering. With sleepy kids and a fridge that looked more like a ghost town, I grabbed some eggs, English muffins, ham, and set out to turn the classic Eggs Benedict into a hands-off, make-ahead dish. The creamy texture, the rich hollandaise, and the way the eggs gently baked into the bread — it was unexpectedly comforting, like a warm hug after a hectic week.

What surprised me most was how this casserole felt like real comfort food but without the usual fuss. It’s creamy, rich, yet simple enough that you can prep it the night before and wake up to a kitchen smelling like a brunch café. I have since made this casserole multiple times, tweaking the hollandaise to my taste, and every time it brings that same cozy feeling — like the food remembers why we cook, to slow down and savor.

So, if you’ve ever wanted to impress with Eggs Benedict but dreaded the poached eggs and sauce juggling, this overnight casserole with homemade hollandaise might just become your new favorite brunch lifesaver. Plus, you’ll find it pairs beautifully with some browned butter banana bread or even a simple side salad for a more balanced meal.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and you can easily swap some to suit your dietary needs.

• English Muffins (6 halves, toasted) – Acts as the base, soaking up the custard and hollandaise.
• Cooked Ham (8 oz / 225 g, diced) – Adds savory, meaty flavor; substitute with Canadian bacon or smoked turkey if preferred.
• Large Eggs (8, room temperature) – The star of the casserole, binding everything together.
• Milk (1 ½ cups / 360 ml, whole or 2%) – For the custard base; whole milk gives more creaminess.
• Heavy Cream (½ cup / 120 ml) – Adds richness to the custard and hollandaise.
• Shredded Cheddar Cheese (1 cup / 100 g) – For melty, sharp flavor; you can swap with Swiss or Gruyère for a twist.
• Butter (1 cup / 225 g, unsalted) – Key for homemade hollandaise (use high-quality butter like Kerrygold for best results).
• Lemon Juice (2 tbsp / 30 ml, fresh) – Brightens the hollandaise, balancing the richness.
• Egg Yolks (3, room temperature) – For the hollandaise sauce base.
• White Vinegar (1 tsp / 5 ml) – Helps stabilize the hollandaise.
• Salt and Pepper – To taste, essential for seasoning custard and sauce.
• Dijon Mustard (optional, ½ tsp) – Adds a subtle tang to the hollandaise.

Look for firm, fresh eggs and choose quality butter to make the hollandaise silky smooth. If you want a lighter version, swap heavy cream with half-and-half or use dairy-free cream alternatives. In summer, I sometimes swap ham for smoked salmon or add fresh herbs like chives for a fresh note.

Equipment Needed

• Baking Dish: A 9×13 inch (23×33 cm) casserole dish works perfectly for layering ingredients evenly.
• Mixing Bowls: At least two—one for the custard mix and one for the hollandaise preparation.
• Whisk: Essential for emulsifying the hollandaise sauce; a balloon whisk works best.
• Double Boiler or Heatproof Bowl: For gently cooking the hollandaise. If you don’t have a double boiler, a heatproof bowl over simmering water does the trick.
• Measuring Cups and Spoons: For precise ingredient amounts, important when working with custards and sauces.
• Spatula: For folding ingredients without deflating.
• Oven Thermometer (Optional): To keep an eye on oven temperature, ensuring even baking.

If you’re on a budget, many of these tools can be multi-purpose or replaced with basics from your kitchen. I’ve made hollandaise with just a sturdy bowl and a whisk over a pot of simmering water countless times, no fancy gadgets needed. Keeping your whisk and bowls clean and dry before starting helps the sauce come together smoothly.

Preparation Method

1. Prepare the English Muffins and Ham: Preheat your oven to 350°F (175°C). Lightly toast the English muffin halves until golden but still slightly firm (about 5 minutes). Dice the ham into small cubes. This step ensures the muffins don’t get too soggy during baking.
2. Mix the Custard: In a large bowl, whisk together 8 large eggs, 1 ½ cups (360 ml) whole milk, ½ cup (120 ml) heavy cream, salt, and pepper until fully combined and smooth. Set aside while you layer the casserole.
3. Assemble the Casserole: Grease your 9×13 inch (23×33 cm) baking dish with butter. Arrange the toasted muffin halves evenly on the bottom. Scatter the diced ham on top, then sprinkle 1 cup (100 g) shredded cheddar cheese over everything. Slowly pour the custard mixture over the layered ingredients, pressing gently on the muffins so they soak up the custard. Let it sit for 5 minutes to absorb.
4. Bake: Cover the dish tightly with foil and bake for 35 minutes. Remove the foil and bake for an additional 15 minutes until the custard is set and the top is lightly golden. A knife inserted in the center should come out clean but moist.
5. Make the Homemade Hollandaise: While the casserole bakes, melt 1 cup (225 g) unsalted butter gently in a saucepan until warm but not browned. In a heatproof bowl, whisk together 3 egg yolks, 2 tablespoons (30 ml) fresh lemon juice, 1 teaspoon (5 ml) white vinegar, a pinch of salt, and ½ teaspoon Dijon mustard (if using). Place the bowl over a pot of gently simmering water (double boiler style), whisking constantly until the mixture thickens slightly (about 3-5 minutes). Slowly drizzle in the melted butter, whisking vigorously until the sauce is thick, creamy, and smooth. Remove from heat and keep warm.
6. Serve: Once the casserole is out of the oven, let it cool for 5 minutes before slicing. Spoon generous amounts of homemade hollandaise over each serving.

Pro tip: If the hollandaise starts to separate, whisk in a teaspoon of warm water to bring it back together. And don’t rush it — patience is key for that silky texture. The first time I made this, I whisked too fast and got little scrambled bits (lesson learned!).

Cooking Tips & Techniques

Making the perfect creamy overnight Eggs Benedict casserole with homemade hollandaise is easier when you keep a few tricks in mind.

• Room Temperature Ingredients: Let eggs and dairy sit out for 30 minutes before cooking. This helps the custard blend smoothly and the hollandaise emulsify without breaking.
• Low and Slow for Hollandaise: Heat the egg yolks gently over simmering water, whisking constantly. High heat cooks the eggs too fast, causing curdling.
• Butter Temperature: Melt butter until warm but not hot or browned. Adding hot butter too fast can scramble the yolks.
• Custard Soak Time: Allow the custard to soak into the English muffins for a few minutes before baking. This ensures the casserole is creamy throughout, not dry in the middle.
• Don’t Overbake: The casserole should be set but still moist. Overbaking leads to dryness. If using a convection oven, reduce temperature by 25°F (15°C) for even cooking.
• Multitask: While the casserole bakes, make the hollandaise. It’s a great way to stay efficient, especially when entertaining.
• Use Fresh Lemon Juice: Bottled lemon juice just doesn’t have the same brightness that cuts through the richness of the sauce.

Years ago, I tried a shortcut hollandaise with a blender and store-bought butter — it tasted okay but lacked the silky, fresh texture of homemade. Since then, whisking by hand has become my favorite way, and it’s surprisingly calming once you get the rhythm.

Variations & Adaptations

This creamy overnight Eggs Benedict casserole is versatile, so you can tweak it depending on your mood or dietary needs.

• Vegetarian Version: Swap the ham for sautéed spinach, mushrooms, or roasted tomatoes for a veggie-packed option. If you miss the smoky flavor, add smoked paprika to the custard.
• Gluten-Free: Use gluten-free English muffins or substitute with cubed gluten-free bread. Ensure your hollandaise ingredients are gluten-free as well.
• Seafood Twist: Try smoked salmon or cooked crab meat instead of ham for a luxurious brunch vibe.
• Dairy-Free Hollandaise: Replace butter with vegan butter or olive oil and use coconut milk for the custard to make this dairy-free. The texture will be slightly different but still tasty.
• Spicy Kick: Add a pinch of cayenne pepper or hot sauce to the hollandaise for some heat.

I once made a mini batch of this casserole topped with fresh herbs and a spoonful of pesto — it gave a lovely herbal freshness that balanced the richness perfectly. Feel free to experiment and make it your own!

Serving & Storage Suggestions

Serve this casserole warm, straight from the oven, with plenty of homemade hollandaise drizzled on top. It’s excellent alongside crisp, fresh fruit or a lightly dressed green salad to add brightness and texture contrast.

For a more indulgent brunch, pair with a glass of sparkling wine or a fresh-squeezed mimosa. If you want a breakfast-for-dinner vibe, it complements simple roasted potatoes or a light vegetable side.

Leftovers store well covered in the refrigerator for up to 3 days. Reheat gently in a 325°F (160°C) oven for 10-15 minutes until warmed through — avoid microwaving as it can make the custard rubbery.

The flavors meld beautifully overnight if you let it rest before baking, making this a great make-ahead option. The hollandaise is best made fresh but can be refrigerated for a day and gently rewarmed in a double boiler.

Nutritional Information & Benefits

Each serving of this casserole provides a hearty balance of protein, fats, and carbohydrates. Eggs and ham offer quality protein and essential amino acids, while the cheddar and butter provide satisfying fats that keep you full.

Rich in vitamins A, D, and B12, this dish supports energy and immune health. Using whole milk and heavy cream adds calcium and vitamin D, important for bone strength.

This recipe is naturally gluten-free if you use appropriate bread, and can be adapted for lower-carb diets by substituting bread with cauliflower crust or low-carb bread.

Keep in mind, the hollandaise sauce is calorie-dense due to butter, so enjoy in moderation if watching fat intake. Personally, I see this as a weekend treat that fuels me for a busy day ahead.
