What Ingredients You Will Need

This recipe leans on simple, wholesome ingredients that come together to create that classic eggs benedict flavor in casserole form. Most of these are pantry staples, so you probably have everything on hand already.

• For the Base Layer:
• English muffins, cut into 1-inch cubes (about 4 whole muffins) – I prefer Thomas’ for their sturdy texture.
• Cooked ham, diced or sliced into bite-size pieces (about 8 oz / 225 g) – use good quality deli ham or leftover ham steak.
• Shredded sharp cheddar cheese (1 cup / 100 g) – adds that melty, tangy punch.
• For the Egg Mixture:
• Large eggs (8) – room temperature helps the custard set evenly.
• Whole milk (1 ½ cups / 360 ml) – provides creaminess, you can swap with almond milk for dairy-free.
• Salt (1 tsp) and freshly ground black pepper (½ tsp) for seasoning.
• Dijon mustard (1 tsp) – a subtle kick that brightens the flavor.
• For the Hollandaise Sauce:
• Unsalted butter (4 tbsp / 55 g), melted – I find Kerrygold gives a richer taste.
• Egg yolks (2) – the rich base for the sauce.
• Fresh lemon juice (1 tbsp) – balances the butter’s richness.
• Salt and cayenne pepper, a pinch each – to taste.

Feel free to swap ham with smoked salmon for a twist or use a mix of cheddar and Gruyère for a nuttier flavor. And if English muffins aren’t your thing, cubed brioche or sourdough bread work nicely too. For dairy-free versions, try coconut milk and vegan butter substitutes.

Equipment Needed

• Baking dish or casserole pan (9×13 inches / 23×33 cm) – a glass or ceramic dish works best for even baking.
• Mixing bowls – one for the egg custard and one for combining ingredients.
• Whisk – for beating eggs and mixing hollandaise sauce.
• Small saucepan – to gently heat butter for the sauce.
• Measuring cups and spoons – precise measurements help with consistent results.
• Optional: Immersion blender or small blender – speeds up hollandaise sauce making and ensures smooth texture.

I’ve tried making this casserole in metal pans and glass, and honestly, glass gives you a better golden crust around the edges. If you don’t have a blender handy, whisk the hollandaise sauce vigorously by hand but expect a bit more elbow grease. For budget-friendly kitchens, any sturdy oven-safe dish will do—the trick is in the layering and timing.

Preparation Method

1. Preheat your oven to 350°F (175°C). Lightly grease your 9×13 inch casserole dish with butter or non-stick spray.
2. Prepare the base: Toss the English muffin cubes, diced ham, and shredded cheddar cheese in a large bowl. Spread this mixture evenly in the bottom of your casserole dish.
3. Make the egg custard: In a separate bowl, whisk together the 8 large eggs, whole milk, salt, pepper, and Dijon mustard until fully combined and slightly frothy. This mix should smell fresh with a hint of mustard brightness.
4. Pour the custard mixture slowly over the English muffin mixture, pressing gently with a spatula to submerge the bread cubes. Let it sit for a few minutes (5-10) so the bread soaks up some of the custard.
5. Cover the casserole dish tightly with aluminum foil or plastic wrap. Refrigerate overnight or for at least 6 hours. This step lets flavors meld and the custard set perfectly.
6. In the morning, bake uncovered for 45–50 minutes until the top is golden and the eggs are set. The center should be slightly jiggly but not liquidy. If it browns too fast, loosely cover with foil.
7. While baking, prepare the hollandaise sauce: In a small saucepan, melt the butter gently over low heat. In a bowl, whisk egg yolks and lemon juice vigorously until thickened (about 2 minutes). Slowly drizzle in melted butter while whisking constantly to avoid curdling. Season with salt and cayenne pepper.
8. Once baked, let the casserole rest for 5 minutes before slicing. Drizzle hollandaise sauce over each portion (or serve on the side) for that classic eggs benedict finish.
9. Serve warm with fresh herbs like chopped chives or parsley for a burst of color and freshness.

If you notice the casserole seems too wet before baking, it’s usually because the bread is very fresh or the custard was a bit loose—just let it sit longer before refrigerating. And don’t panic if the hollandaise sauce looks a little thin at first; a quick whisk off heat will bring it back to velvety perfection.

Cooking Tips & Techniques

Making a baked eggs benedict casserole might sound fancy, but honestly, it’s all about layering flavors and timing. Here are some tips I’ve picked up from trial and error (and a few kitchen mishaps):

• Use slightly stale bread: If your English muffins are too fresh, they won’t soak up the custard properly and can make the casserole soggy. Let them sit out a day, or toast lightly before cubing.
• Room temperature eggs and milk: This helps the custard mixture blend smoothly without clumping or curdling during baking.
• Don’t skip the resting time: The overnight soak is crucial; rushing it can make the casserole less cohesive and dull the flavors.
• Watch your oven temperature: Too hot and the top burns before the center sets; too low and it may take forever to cook through. 350°F (175°C) is the sweet spot.
• Whisk hollandaise sauce off heat: To avoid scrambled eggs in your sauce, remove from heat while whisking and add butter slowly.
• Multitask: I often start the hollandaise while the casserole bakes, so everything’s ready at once. It saves time and ensures the sauce is fresh.

One time I forgot to cover the casserole overnight, and the top dried out a bit – lesson learned! Covering prevents that and keeps the custard silky. Also, mixing ham with a bit of cooked spinach or sautéed mushrooms can add a nice twist without extra fuss.

Variations & Adaptations

This casserole is a fantastic base for creativity. Here are a few ways I’ve tweaked it depending on mood, season, or what’s in the fridge:

• Vegetarian Version: Swap ham for sautéed mushrooms, spinach, or sun-dried tomatoes. I once added caramelized onions for a sweet-savory punch that was surprisingly addictive.
• Seafood Twist: Use smoked salmon instead of ham, and add a touch of dill to the hollandaise. It feels fancy but stays simple.
• Gluten-Free: Substitute English muffins with gluten-free bread cubes or even cooked quinoa for a different texture.
• Spicy Kick: Add chopped jalapeños or a dash of hot sauce to the custard mixture for some heat.
• Cheese Swap: Try Gruyère, mozzarella, or pepper jack for different flavor profiles.

Personally, I found adding a handful of fresh herbs like tarragon or chives to the egg mixture adds a lovely freshness, especially in spring. And when I’m feeling extra indulgent, a sprinkle of crispy bacon on top before baking never hurts!

Serving & Storage Suggestions

This casserole is best served warm, fresh out of the oven with that silky hollandaise drizzled over the top. Pair it with a light green salad or some crisp roasted potatoes for a balanced brunch plate. A mimosa or freshly brewed coffee rounds it out perfectly.

Leftovers keep well in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 325°F (160°C) for about 15 minutes or until warmed through. Avoid microwaving if possible—it can make the eggs rubbery.

Flavors actually deepen after resting, so sometimes I make the casserole a day in advance, bake it fresh in the morning, and have the hollandaise ready to go. It’s a game-changer for stress-free entertaining.

If freezing, cover tightly with foil and freeze for up to 1 month. Thaw overnight in the fridge before baking as usual.
