Overnight Eggs Benedict Casserole with Blender Hollandaise

Experience the luxurious flavors of traditional Eggs Benedict without the morning rush. This casserole combines buttery English muffins, savory Canadian bacon, and a custardy egg mixture, all baked into one glorious dish. Topped with velvety hollandaise sauce, it’s a brunch showstopper that’s simple to assemble the night before.

Why This Casserole Beats Individual Eggs Benedict

Classic Eggs Benedict demands poaching eggs, toasting muffins, and perfecting hollandaise on the spot—challenging for crowds. This version streamlines everything into a single pan. Layer ingredients, pour over seasoned eggs and dairy, refrigerate overnight, then bake. The result mimics the original: crisp muffin edges, tender bacon, set custard, and that iconic sauce drizzle.

Perfect for holidays like Christmas or Easter, weekend gatherings, or feeding a family after sleep-ins. It serves 8-12 generously, scaling easily for smaller groups.

Essential Ingredients Breakdown

Gather these staples for authentic taste with minimal effort. Quantities yield a 9×13-inch dish.

• 6-10 English muffins, split and cubed or halved—provides the bready base that soaks up custard without sogginess.
• 12-16 oz Canadian bacon or ham slices—smoky, lean protein that layers beautifully.
• 8-12 large eggs—forms the rich, custardy binder.
• 2-3 cups milk or cream mix (half milk, half heavy cream ideal)—creates fluffiness and creaminess.
• Spices: 1 tsp each garlic/onion powder, salt, ½ tsp pepper, pinch paprika/nutmeg—enhances savory depth.
• Hollandaise: egg yolks, butter, lemon juice, Dijon, cayenne—blender method for foolproof results.
• Optional: chives, cheese like Gruyere for extra indulgence.

Pro tip: Use day-old English muffins for better texture absorption.

Step-by-Step Assembly Guide

Prep time: 20 minutes. Chill: 8+ hours. Bake: 45-60 minutes.

1. Prep dish: Grease a 9×13 baking pan with butter or spray.
2. Layer base: Scatter half the English muffin pieces or halves. Top with half the Canadian bacon. Repeat layers.
3. Mix custard: Whisk eggs, milk/cream, spices until smooth. Pour evenly over layers, pressing down to submerge. Cover tightly; refrigerate overnight.
4. Bake: Preheat oven to 350°F. Bake covered 30 minutes, uncover for 15-30 more until center sets (160°F internal). Rest 5-10 minutes.
5. Make hollandaise: While baking, blend yolks, lemon juice, mustard, salt, cayenne. Slowly add hot melted butter until thickened. Drizzle over baked casserole.

Serve warm with fresh parsley or paprika sprinkle.

Mastering Foolproof Hollandaise Sauce

Hollandaise elevates this dish—creamy, tangy, buttery. Traditional double-boiler risks curdling; blender method is heat-stable and quick (2 minutes).

Steps: Blend yolks and acids 30 seconds. With blender running, pour hot butter in thin stream. Sauce thickens instantly. Keep warm in thermos if needed. Yields 1 cup, enough for full casserole.

Customizations for Every Palate

Adapt to preferences or dietary needs without losing essence.

• Vegetarian: Swap bacon for spinach, mushrooms, or asparagus.
• Spicy kick: Add diced jalapeños or extra cayenne to custard.
• Cheesy twist: Mix in 1 cup shredded cheddar or Gruyere before baking.
• Gluten-free: Use GF English muffins; ensure bacon is GF.
• Light version: All milk instead of cream; turkey bacon.
• Seafood vibe: Smoked salmon instead of bacon for lox Benedict style.

Storage: Refrigerate leftovers up to 3 days; reheat at 325°F covered. Freeze unbaked casserole up to 2 months—thaw overnight before baking.
