Easy Overnight Eggs Benedict Casserole Recipe with Roasted Red Pepper Hollandaise

“You really think this will taste like Eggs Benedict?” My sister tossed a skeptical glance my way as I pulled the casserole out of the fridge that Sunday morning. Honestly, I wasn’t sure either. Eggs Benedict has always felt like a fancy, delicate thing to make on the spot. Hollandaise sauce alone can be a beast to handle, and poached eggs? A little nerve-wracking. But, after a chaotic week filled with early meetings and late-night emails, I needed something that could feel both indulgent and effortless.

The night before, I threw together this easy overnight Eggs Benedict casserole with roasted red pepper hollandaise, mostly on a whim and with a bit of leftover bread and ham in the fridge. I was half-expecting it to be a flop, but that morning, the kitchen filled with the warm scent of baked eggs and smoky ham. The sauce? That vibrant roasted red pepper hollandaise added a subtle kick and color that made me pause mid-bite.

It wasn’t just a meal; it was a quiet victory — the kind that hits just right when you don’t want to fuss but still want something special. My sister, ever the skeptic, ended up asking for the recipe (and yes, she’s made it twice since). What stuck with me was how this casserole somehow made brunch feel like a cozy reset. It’s the kind of dish you can prepare ahead, sleep on, and wake up to with minimal stress, yet it still feels like a treat worth savoring.

So yeah, this recipe isn’t just about eggs and sauce. It’s a little pocket of calm in the chaos, a reminder that sometimes, the best dishes come from the simplest ideas — and a little bit of trust in the oven.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients that come together to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions are easy if needed.

• For the Casserole:
• 8 large eggs, beaten (room temperature for best results)
• 2 cups whole milk (or 2% for a lighter option)
• 6 cups cubed day-old bread (I prefer sourdough for its tang and texture)
• 1 ½ cups diced cooked ham (leftover ham works perfectly)
• 1 cup shredded sharp cheddar cheese (or a blend of cheddar and Gruyère for richness)
• 2 tablespoons Dijon mustard (adds a subtle tang)
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 tablespoon fresh chives, chopped (optional, for garnish)
• For the Roasted Red Pepper Hollandaise:
• 3 large egg yolks
• 1 tablespoon fresh lemon juice
• 1 teaspoon Dijon mustard
• 6 tablespoons unsalted butter, melted and warm (I recommend Kerrygold for creaminess)
• ½ cup roasted red peppers, drained and pureed (jarred roasted red peppers work great)
• Pinch of cayenne pepper (optional, for mild heat)
• Salt and white pepper to taste

Ingredient Tips: Using day-old bread is key for soaking up the custard without turning mushy. If you don’t have ham, smoked turkey or cooked bacon are good swaps. For dairy-free options, almond or oat milk works for the casserole, and you can substitute vegan butter in the hollandaise. If you want to add a bit more green, finely chopped spinach stirred into the casserole adds a fresh touch.

Equipment Needed

• 9×13 inch baking dish (glass or ceramic works well for even baking)
• Mixing bowls (one large for the custard and another small for the hollandaise)
• Whisk (a sturdy one for the hollandaise helps get a smooth sauce)
• Blender or food processor (for pureeing the roasted red peppers)
• Small saucepan or double boiler (to gently cook the hollandaise sauce)
• Measuring cups and spoons
• Rubber spatula or spoon for folding ingredients

For those who don’t have a blender handy, you can finely chop the roasted red peppers and whisk them into the hollandaise, though the texture won’t be as silky. If you’re wary of making hollandaise on the stove, a gentle water bath setup or a heat-safe bowl resting over simmering water helps prevent scrambling the eggs. And honestly, a good non-stick pan makes cleanup easier after this breakfast treat.

Preparation Method

1. Prepare the Casserole Base: In a large bowl, whisk together the beaten eggs, milk, Dijon mustard, salt, and pepper until fully combined. This mixture will be your custard that soaks into the bread cubes.
2. Assemble the Casserole: Lightly grease your 9×13 inch baking dish. Layer half of the cubed bread evenly on the bottom, then scatter half of the diced ham and shredded cheese over the bread. Repeat with the remaining bread, ham, and cheese layers.
3. Pour the Custard: Slowly pour the egg and milk mixture over the layered bread, pressing down gently with a spatula to ensure all the bread is soaked. Cover the dish tightly with plastic wrap or foil and refrigerate overnight or for at least 6 hours. This step lets the bread soak up the custard fully.
4. Make the Roasted Red Pepper Hollandaise: The next morning, start by pureeing the roasted red peppers in a blender until smooth. In a small heatproof bowl, whisk the egg yolks, lemon juice, and Dijon mustard until pale and thick.
5. Cook the Hollandaise: Place the bowl over a pot of gently simmering water (double boiler setup), whisking constantly. Slowly drizzle in the warm melted butter while whisking vigorously until the sauce thickens and doubles in volume. Remove from heat and stir in the pureed roasted red peppers, cayenne pepper, and season with salt and white pepper. Keep warm until ready to serve.
6. Bake the Casserole: Preheat your oven to 350°F (175°C). Remove the casserole from the fridge and uncover. Bake for 45–50 minutes until the top is golden brown and the custard is set but still slightly jiggly in the center. A knife inserted should come out mostly clean.
7. Serve: Let the casserole rest for 5 minutes after baking. Spoon generous portions onto plates and drizzle with the warm roasted red pepper hollandaise. Garnish with chopped chives for a fresh finish.

Pro Tip: If your casserole looks too dry before baking, sprinkle a little extra milk over the top and gently press down to moisten. Also, don’t skip the resting time after baking — it helps the custard finish setting and makes serving cleaner.

Cooking Tips & Techniques

Making hollandaise can be intimidating, but patience and gentle heat are your best friends here. Whisk constantly, and don’t let the bowl get too hot to avoid scrambling. If you notice your sauce starting to separate, whisk in a teaspoon of cold water to bring it back together.

For the casserole, use firm, day-old bread — fresh bread absorbs too much custard and can get soggy. If you’re short on time, cubing the bread and toasting it lightly before assembling helps it hold up better. I’ve learned this after a couple of soggy attempts!

Timing is important. The overnight soak lets the flavors meld and the texture develop, so don’t rush that step. Baking low and slow at 350°F ensures the eggs cook evenly without drying out. You can multitask by making the hollandaise while the casserole bakes, so everything is ready together.

When serving, gently rewarm leftover casserole slices in the oven or microwave, and freshen up the flavor with a quick drizzle of warmed hollandaise. It’s a little trick I picked up from making creamy salmon dip for gatherings — fresh sauce can revive almost any dish.

Variations & Adaptations

This eggs benedict casserole is flexible and can be adjusted to suit your taste or dietary needs:

• Vegetarian Version: Swap the ham for sautéed mushrooms or roasted asparagus for a meat-free option. Adding a little smoked paprika helps mimic the smoky flavor.
• Spicy Kick: Mix diced jalapeños into the casserole or add a pinch of smoked chipotle powder to the hollandaise for a smoky heat.
• Gluten-Free: Use gluten-free bread cubes or substitute with roughly chopped cooked potatoes for a hearty base.
• Dairy-Free: Swap milk for almond or oat milk, and use vegan butter in the hollandaise. The texture changes slightly but remains tasty.
• Herb Variation: Stir fresh dill or tarragon into the custard for a fresh herbal note. This change pairs beautifully with the roasted red pepper hollandaise and echoes flavors found in my fresh shrimp salad appetizers.

One personal favorite twist is adding a layer of caramelized onions beneath the ham, which adds sweetness and depth. It’s a little extra step but worth it if you want to impress guests without feeling overwhelmed.

Serving & Storage Suggestions

This casserole shines best served warm, straight from the oven with a drizzle of the roasted red pepper hollandaise. Garnish with fresh chives or even a sprinkle of smoked paprika for a pop of color. Pair it with a simple green salad or fresh fruit for balance.

Leftovers keep well in an airtight container in the fridge for up to 3 days. When reheating, use a low oven (around 300°F/150°C) to keep the texture creamy without drying out. Avoid microwaving if possible, but if you must, cover loosely to trap moisture.

The flavors actually deepen after a day or two, especially the hollandaise, which melds beautifully with the savory custard. If you want to prep ahead for a brunch party, this casserole can be baked the night before and gently reheated — perfect if you’re also serving something like creamy cheese stuffed cherry tomatoes alongside it.

Frequently Asked Questions

Can I use regular eggs instead of large eggs for this casserole?

Large eggs are standard for most recipes, but if you only have medium eggs, you can use about 1.25 medium eggs per large egg. For this casserole, it’s best to stick close to the amount to keep the custard texture balanced.

Is the roasted red pepper hollandaise sauce difficult to make?

It’s easier than classic hollandaise because the red peppers add flavor and color, and pureeing them helps smooth the sauce. Just keep the heat low and whisk constantly to avoid scrambling the yolks.

Can I prepare the hollandaise sauce ahead of time?

Hollandaise is best served fresh but can be made a few hours ahead and kept warm in a thermos or over very low heat. Avoid reheating too much as it can separate.

What can I substitute for the ham if I want a vegetarian option?

Sautéed mushrooms, roasted asparagus, or even caramelized onions work well as meat alternatives and add a different but delicious flavor.

How do I store and reheat leftovers without drying out the casserole?

Store leftovers in an airtight container in the fridge. Reheat gently in a low oven at 300°F (150°C) until warm. Avoid the microwave if possible, or cover the dish loosely to retain moisture.
