Prep and Cook Time

Preparation: 20 minutes
Cooking: 45 minutes
Total: 65 minutes

Yield

Serves 6 generous portions

Difficulty Level

Easy to Medium: Perfect for both novice and seasoned home chefs

Ingredients

• 8 large eggs, room temperature
• 2 cups whole milk
• 1 teaspoon Dijon mustard
• 1/2 teaspoon freshly ground black pepper
• 1/2 teaspoon kosher salt
• 1 tablespoon olive oil
• 1 medium yellow onion, finely diced
• 2 cloves garlic, minced
• 2 cups baby spinach, roughly chopped
• 1 cup cooked bacon or sausage, crumbled
• 1 1/2 cups shredded sharp cheddar cheese
• 1 cup halved cherry tomatoes
• 1/4 cup fresh chives, thinly sliced
• Optional: 1/2 cup cooked diced potatoes for added heartiness

Instructions

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish with olive oil or non-stick spray.
2. Whisk together the eggs, whole milk, Dijon mustard, salt, and black pepper until fully combined and slightly frothy. Set aside.
3. Heat olive oil in a large skillet over medium heat. Add diced onion and sauté until translucent and golden, about 5 minutes. Stir in minced garlic and cook for an additional 1 minute to release aroma.
4. Add chopped spinach to the skillet and sauté until wilted, approximately 2 minutes. Remove from heat and let cool slightly.
5. In a large mixing bowl, combine the cooked spinach mixture, crumbled bacon or sausage, half the shredded cheddar, and optional cooked potatoes.
6. Pour the egg mixture into the bowl and gently fold all ingredients together until evenly distributed.
7. Transfer the mixture to the prepared casserole dish and scatter cherry tomatoes and remaining cheddar cheese evenly on top.
8. Bake uncovered for 40-45 minutes, or until the casserole is set and the top is golden brown. A knife inserted near the center should come out clean.
9. Allow to cool for 5 minutes before slicing to maintain structural integrity.

Tips for Success

• Use room temperature eggs to create a smoother, more uniform casserole texture.
• Customize proteins with smoked salmon, pancetta, or sautéed mushrooms for variety.
• For extra creaminess, swap whole milk for half-and-half or add 1/4 cup sour cream to the egg mixture.
• Make-ahead tip: Assemble the casserole the night before, cover tightly with foil, refrigerate, and bake fresh in the morning-just add 5-10 minutes to the baking time.
• To prevent sogginess, drain cooked vegetables well and pat dry before mixing.

Serving Suggestions

Present slices of this vibrant brunch casserole on warm plates garnished with a sprinkle of fresh chives and a light drizzle of herbed Greek yogurt or crème fraîche for a tangy balance. Complement with a simple arugula salad tossed in lemon vinaigrette for refreshing contrast. Flaky, buttery croissants or crusty whole-grain toast make excellent accompaniments that invite guests to customize each bite.

Q&A

Q&A: Deliciously Simple Brunch Casseroles to Brighten Your Day

Q1: What makes a brunch casserole “deliciously simple”?
A1: A brunch casserole earns the “deliciously simple” title when it combines easy-to-find ingredients with straightforward prep, yet delivers comforting layers of flavor. Think minimal chopping, one-pan baking, and no obscure spices-just wholesome, hearty elements that come together effortlessly and taste like a warm, loving hug.

Q2: Why are casseroles a perfect choice for brunch?
A2: Casseroles are the ultimate brunch MVP because they’re make-ahead wonders that free you up on busy mornings. They’re crowd-pleasers too, serving multiple hungry guests with little fuss. Plus, casseroles blend breakfast staples-eggs, cheese, bread, and veggies-into a savory, cozy dish that’s filling and festive.

Q3: What are some key ingredients to stock for brunch casseroles?
A3: Keep your fridge and pantry brunch-ready with staple ingredients like eggs, shredded cheese (cheddar, mozzarella, or your favorite mix), fresh bread or tortillas, milk or cream, and a medley of veggies such as spinach, bell peppers, or mushrooms. Don’t forget savory add-ins like cooked bacon, sausage, or smoked salmon to give your casserole an irresistible upgrade.

Q4: Can brunch casseroles be customized for different diets?
A4: Absolutely! Brunch casseroles are wonderfully adaptable. For a vegetarian twist, ramp up the veggies and swap meat for plant-based proteins like tofu or tempeh. Low-carb fans can replace bread with cauliflower rice or skip the starch altogether. Dairy-free options work well with almond or oat milk and vegan cheese. The fun is in tailoring the casserole to your tastes and needs.

Q5: How far ahead can I prepare a brunch casserole?
A5: You can assemble most brunch casseroles a day in advance-simply cover and refrigerate overnight. Baking them fresh in the morning ensures a warm, bubbly finish. Some casseroles even freeze beautifully, so you can double the batch and save one for a quick future brunch fix.

Q6: Any pro tips for ensuring a perfectly baked brunch casserole?
A6: To achieve that ideal balance of creamy and firm, let your casserole rest for about 10 minutes after baking; this helps it set and slice cleanly. Use a moderate oven temperature (around 350°F/175°C) for even cooking without drying. And don’t shy away from seasoning boldly-herbs like thyme, rosemary, or chives add bright notes that lift the whole dish.

Q7: What’s a simple yet crowd-pleasing brunch casserole recipe to try?
A7: Try a Classic Ham and Cheese Breakfast Casserole: Layer cubed day-old bread with diced ham and shredded cheddar. Whisk eggs with milk, a pinch of salt, pepper, and a splash of Dijon mustard. Pour over the bread mixture, sprinkle with extra cheese, then bake until golden and puffed. It’s the kind of dish that disappears fast at the table and leaves everyone smiling.

With these answers, you’re ready to brighten your morning-and your guests’-with deliciously simple brunch casseroles that blend ease and elegance in every bite!
