Torn English muffins hold shape rather than dissolving, creating pockets of chewy toast that soak up custard and emerge with a golden, slightly crisp top. The quick hollandaise preserves that silky, lemony finish without the stress of poaching a dozen eggs. What makes this version work is deliberate restraint — the custard-to-bread ratio is tuned so the casserole sets as a custardy strata instead of a soggy bake, while a 20–30 minute rest (or an overnight hold) lets the muffin pieces hydrate evenly. It’s made for hosts who want restaurant flavors with minimal last-minute work: assemble ahead, bake while you greet guests, and spoon warm hollandaise on just before serving so each portion still feels fresh and indulgent. ## Recipe Information - Prep Time: 25 minutes - Cook Time: 35 minutes - Total Time: 60 minutes - Servings: 5 - Difficulty: Medium - Category: Baking ## Ingredients ### Preheat and assemble base - 6 count English muffins, torn into 1-inch pieces - 12 slices Canadian bacon, sliced or diced ### Make custard and add cheese - 8 count Large eggs (for the casserole) - 2 cups Whole milk - 2 tsp Dijon mustard - 1 1/2 cups Shredded Gruyère (or sharp cheddar) - 1 tsp Kosher salt and freshly ground black pepper ### Prepare quick hollandaise - 8 tbsp Unsalted butter (for hollandaise / dotting) - 3 count Egg yolks (for quick hollandaise) - 2 tbsp Fresh lemon juice ## Ingredient Guide ### Shredded Gruyère (or sharp cheddar) Gruyère is a firm cow’s‑milk cheese from the Alps (Switzerland/France border) known for its rich, nutty, slightly sweet flavor and relatively low acidity. It has a savory, earthy aroma and melts smoothly, which makes it popular in gratins, fondues, and egg dishes. You can find it at supermarket cheese counters, specialty cheese shops, or well‑stocked grocery stores; good substitutes are Emmental, Comté, Jarlsberg, or the listed sharp cheddar if you prefer a more familiar flavor. ## Instructions ### 1. Preheat and assemble base Preheat the oven to 350°F (175°C). Butter a 9x13-inch (23x33 cm) baking dish, spread torn English muffin pieces evenly across the bottom, then scatter the Canadian bacon over the muffins so every serving has meat. ### 2. Make custard and add cheese In a large bowl, whisk the 8 eggs with the milk, Dijon mustard, and salt and pepper until smooth. Stir in the shredded Gruyère, then pour the mixture evenly over the muffin and bacon layers, pressing gently so bread soaks up the custard. ### 3. Rest and bake Let the assembled casserole sit 20–30 minutes at room temperature to absorb the custard (or cover and refrigerate up to 24 hours for make-ahead). Bake uncovered at 350°F (175°C) for 30–35 minutes, until the center is set and the top is golden. ### 4. Prepare quick hollandaise While the casserole bakes or shortly before serving, melt the butter until hot. Whisk the 3 egg yolks with lemon juice in a heatproof bowl and place over a gentle simmer (or quickly use a blender). Slowly stream the hot butter into the yolks while whisking constantly until thickened and emulsified; season to taste. If using a blender, add warm melted butter in a thin stream for a quick, stable hollandaise. ### 5. Serve, hold warm, and reheating tips Spoon hollandaise over portions and garnish with chives if desired. To hold for service: keep the casserole covered in a 200°F (95°C) oven for up to 30–45 minutes (avoid drying by tenting foil) or serve from a chafing dish/bain-marie. Reheating: slices from chilled can be warmed in a 325°F oven for 20–25 minutes or microwave individual portions briefly, and reheat hollandaise gently over warm water or keep in a thermos for up to 1 hour. ## Nutrition Estimated nutrition per serving (1 serving): - Calories: 767 kcal - Protein: 43.6 g - Carbohydrates: 38.8 g - Fat: 48.2 g - Saturated Fat: 24.7 g - Fiber: 1.6 g - Sugar: 9.2 g - Cholesterol: 548.4 mg - Sodium: 1830.6 mg - Potassium: 625.9 mg - Calcium: 598.8 mg - Iron: 4.4 mg - Vitamin D: 3.8 mcg ## Tips ### Dry the muffin pieces Lightly toast torn muffin pieces for 5–8 minutes or leave them out uncovered overnight to reduce excess moisture so they absorb custard without turning gluey. ### Press, don’t compress After pouring the custard, press the bread gently to help it absorb liquid but avoid compacting the mixture, which leads to a dense bake. ### Rest before baking Allow the assembled casserole to sit 20–30 minutes (or refrigerate up to 24 hours) so the custard hydrates the bread evenly and bakes to a uniform set. ### Layer cheese strategically Stir most of the Gruyère into the custard for melt and flavor, then sprinkle a little on top for attractive browning and a slight crust. ### Stabilize the hollandaise Make hollandaise in a blender or whisk yolks over a gentle bain-marie and add the hot butter in a slow stream; if it separates, whisk in a teaspoon of warm water to bring it back. ## Variations and Substitutions ### Smoked salmon Benedict Swap Canadian bacon for flaked smoked salmon and fold in a tablespoon of chopped capers and fresh dill; reduce or omit the Gruyère to let the salmon shine. ### Vegetarian bake Replace the Canadian bacon with a mix of sautéed mushrooms, spinach, and caramelized onions for umami depth; consider using Gruyère or a sharp cheddar for a robust finish. ### Gluten-free option Use day-old gluten-free rolls or a sturdy gluten-free loaf torn into 1-inch pieces — toast them first to dry out and reduce sogginess, and proceed as written. ### Richer custard Swap one cup of whole milk for heavy cream or half-and-half for a silkier, more luxurious custard; reduce baking time slightly if the casserole is shallower. ## Notes This casserole turns classic Eggs Benedict flavors into an easy, pan-served dish perfect for weekend brunches or holiday gatherings. Home cooks will appreciate the ability to assemble the night before and the straightforward hollandaise that can be held or gently reheated. ### Storage and Make-Ahead Cool leftovers completely, then refrigerate in an airtight container for up to 3 days. Store hollandaise separately in a small airtight container for up to 24 hours and reheat gently over a warm water bath, whisking to re-emulsify; if it’s thickened too much, whisk in a splash of warm water or lemon juice. Reheat casserole slices in a 325°F oven for 20–25 minutes covered with foil, or microwave individual portions briefly and finish under the broiler to refresh the top. ### Serving Suggestions Serve squares spooned with warm hollandaise and scattered chives or chopped parsley for freshness. Pair with crisp, peppery arugula tossed in lemon vinaigrette, roasted breakfast potatoes or a skillet of herb-roasted fingerlings, and bright beverages like mimosas, a light sparkling rosé, or strong coffee to cut the richness. ## Frequently Asked Questions ### Why is my casserole soggy in the middle? Sogginess usually comes from under-toasted bread or not enough resting time; next time toast the muffin pieces until lightly golden and allow the assembled pan to sit 20–30 minutes so the bread absorbs the custard before baking. If baking from chilled, add 5–10 minutes to ensure the center sets. ### Can I assemble this the night before? Yes — cover and refrigerate up to 24 hours, then bake straight from the fridge (you may need 5–10 extra minutes). Bring the dish closer to room temperature for 15 minutes before baking if you want more even cooking. ### My hollandaise broke — how can I fix it? Rescue it by whisking in a teaspoon of warm water or lemon juice, or start with a single fresh yolk in a clean bowl and slowly whisk the broken sauce into it to re-emulsify. Using a blender makes it quicker to stabilize. ### Can I use half-and-half or non-dairy milk? Half-and-half will make a richer, silkier custard and works well; non-dairy milks will change texture and flavor — use full-fat coconut or oat for best results and expect a slightly different set. ### How do I keep portions warm for serving? Keep the casserole loosely tented in a 200°F oven for up to 30–45 minutes to hold without drying, or serve from a bain-marie or chafing dish. Keep hollandaise warm over a very gentle bain-marie and whisk occasionally. ## Related Recipes and Guides - [Cloud Bread Sandwiches](https://www.topshelf.recipes/recipes/cloud-bread-sandwiches) - [Honey Mustard Chicken Nuggets](https://www.topshelf.recipes/recipes/honey-mustard-chicken-nuggets-baked) - [Cheddar Jalapeño Corn Muffins](https://www.topshelf.recipes/recipes/cheddar-jalapeno-corn-muffins) - [Basque Burnt Cheesecake](https://www.topshelf.recipes/recipes/basque-burnt-cheesecake-salted-caramel) - [30-Minute Sticky Baked Honey Garlic Chicken Thighs with Crisp Edges](https://www.topshelf.recipes/recipes/30-minute-sticky-baked-honey-garlic-chicken-thighs-crisp-edges) - [Lemon Butter Salmon](https://www.topshelf.recipes/recipes/lemon-butter-salmon) - [Baking Soda and Tenderized Beef](https://www.topshelf.recipes/articles/baking-soda-and-meat) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan) - [Low-Fat Grill Swaps for Big Flavor](https://www.topshelf.recipes/articles/low-fat-grill-swaps-big-flavor)
