How to Make Overnight Eggs Benedict Casserole
-
Prepare Muffins: Spread the English muffin cubes evenly on a baking sheet to dry out overnight. Alternatively, toast them briefly under the grill until just crisp to enhance their texture.
-
Layer Ingredients: Grease a 32 × 20 cm baking dish with cooking spray. Arrange half of the dried muffin cubes at the bottom, followed by half of the cubed ham and half of the shredded cheddar cheese. Repeat this layering, finishing with the remaining cheese.
-
Mix Custard: In a large bowl, vigorously whisk together the half and half, eggs, salt, pepper, mustard powder, granulated garlic, onion powder, thyme, and nutmeg until everything is smooth and well combined.

Soak Muffins: Pour the custard mixture evenly over the layered ingredients. Gently press the muffin cubes into the custard with the back of a spoon, ensuring they’re fully absorbed. Cover tightly with plastic wrap and refrigerate overnight.

Bake Casserole: Preheat your oven to 175°C (350°F). Remove the dish from the fridge about 15 minutes before baking. Dot the surface with cubed butter and sprinkle lightly with paprika.

Overnight Eggs Benedict Casserole Recipe FAQs
What is the best way to select ripe ingredients for my casserole?
Absolutely! When selecting ingredients, choose English muffins that feel firm and slightly springy, with no visible mold. For the Canadian bacon or smoked ham, look for slices that are bright and moist; avoid any that appear dried out. Cheese should be fresh and smell pleasant, and opt for sharp white cheddar for the best flavor infusion.
How should I store leftovers of the casserole?
Very easy! Store any leftovers in an airtight container in the refrigerator for up to 3 days. If there are portions left that you won’t eat immediately, keep them separate to maintain freshness.
Can I freeze my Overnight Eggs Benedict Casserole for later use?
Definitely! To freeze, let the casserole cool completely after baking. Wrap it tightly using plastic wrap and then aluminum foil to prevent freezer burn. It can be frozen for up to 3 months.
What’s the best way to reheat frozen casserole?
When you’re ready to enjoy it, simply thaw the frozen casserole overnight in the fridge. Preheat your oven to 175°C (350°F), then reheat it covered with foil for about 25 to 30 minutes, or until thoroughly warmed. This way, you’ll get that delicious, fresh-out-of-the-oven taste again!
What if my casserole turns out soggy or undercooked?
If you find your casserole soggy, it could be due to using too much liquid or not dried muffins. In future preparations, ensure the English muffins are adequately dried or toasted before layering. If it’s undercooked, you may not have baked it long enough; just keep an eye on the baking time and stick a knife in the center to check for doneness—it should come out clean!
Are there any dietary considerations for this recipe?
Absolutely! If you’re catering to gluten-free diets, substitute the English muffins with gluten-free bread. For dairy-free options, try using a dairy-free cheese alternative and plant-based cream. Always check labels for any allergies, such as lactose intolerance, ensuring that all ingredients are suitable for your guests.
