Sustained Energy for Busy Days

This casserole isn’t just delicious; it’s incredibly filling. The combination of protein from the ham and eggs, complex carbohydrates from the hash browns, and essential vitamins from the vegetables provides a balanced meal that truly “sticks to your bones.” This means fewer mid-morning hunger pangs, better concentration in class, and sustained energy for both kids and adults throughout their morning activities. It’s the ultimate brain-boosting breakfast.

Unbeatable Convenience: Perfect for Make-Ahead Meals

One of the biggest struggles during busy mornings is finding time to prepare a nutritious meal. This casserole is a dream come true for meal prepping. You can assemble it the night before, cover it, and store it in the refrigerator. In the morning, simply pop it into the oven, and within minutes, a hot, homemade breakfast is ready to serve. This make-ahead capability is a game-changer for easing morning rush hour stress.

Endless Customization for Every Palate

This recipe is wonderfully versatile, allowing you to tailor it to your family’s preferences or whatever ingredients you have on hand. Not a fan of ham? No problem! Swap it for crumbled sausage, crispy bacon, or even a vegetarian protein. The vegetable blend is also completely flexible – think spinach, bell peppers of different colors, zucchini, or even diced sweet potatoes. And when it comes to cheese, the options are limitless, from sharp cheddar to mozzarella, or a spicy pepper jack. This adaptability ensures that everyone finds something to love in every bite.

While perfect for daily family breakfasts, this casserole also shines when entertaining.

Essential Ingredients for Your Hearty Casserole

Crafting the perfect breakfast casserole starts with quality ingredients. Here’s what you’ll need for this flavorful Ham and Vegetable Hash Brown Breakfast Casserole:

  • Olive Oil: For sautéing our vibrant vegetables.
  • White Button Mushrooms: Sliced for a savory, earthy depth.
  • Yellow Onion: Finely chopped, adding a sweet aromatic base.
  • Green Pepper: Finely chopped, providing a fresh crunch and color.
  • Large Eggs: The foundational binder that creates a fluffy, satisfying texture.
  • Heavy Cream: Ensures a rich, creamy consistency for the egg mixture.
  • Salt & Pepper: Essential seasonings to enhance all the flavors.
  • Dijon Mustard: A secret ingredient that adds a subtle tang and brightens the overall taste without being overpowering.
  • Diced Ham: Pre-cooked and ready to add a savory, salty punch.
  • Colby Jack Cheese: Freshly shredded for superior melting and a creamy, mild flavor that everyone loves.
  • Refrigerated Shredded Hash Brown Potatoes: The convenient and comforting base of our casserole, providing that classic breakfast texture.

Ingredient Spotlight: Tips for Best Results

  • Cheese: We highly recommend using freshly shredded cheese over pre-shredded bags. Freshly shredded cheese melts much more smoothly and integrates beautifully into the casserole, avoiding the slightly gritty texture that pre-packaged varieties can sometimes yield.
  • Hash Browns: While refrigerated hash browns are incredibly convenient, you can also use frozen hash browns. If using frozen, make sure to thaw them completely and squeeze out any excess moisture before adding them to the mixture. This step is crucial to prevent a watery casserole.
  • Ham: Leftover holiday ham works wonderfully here! If using a ham steak, simply dice it to the appropriate size.

Step-By-Step Guide to Casserole Perfection

Creating this delicious breakfast casserole is straightforward. Follow these simple steps for a truly satisfying meal:

Step 1: Sauté Your Vegetables to Perfection

Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with nonstick spray and set it aside. In a large skillet, heat two tablespoons of olive oil over medium-high heat. Add your sliced white button mushrooms and cook, stirring frequently, until they release their moisture and begin to brown beautifully, usually about 5-6 minutes. This browning step is crucial as it deepens their flavor. Next, add your finely chopped yellow onions and green peppers to the skillet. Continue to cook, stirring occasionally, for another 3-4 minutes, until the vegetables are just slightly softened. You want them tender-crisp, not mushy. Remove the skillet from the heat and set the cooked vegetables aside to cool slightly.

Step 2: Assemble the Flavorful Egg Mixture

In a large mixing bowl, crack your 12 large eggs and whisk them vigorously until the yolks and whites are fully combined and slightly frothy. This aeration helps create a lighter casserole. Next, whisk in the heavy cream, Dijon mustard, salt, and pepper until everything is thoroughly incorporated. The Dijon mustard provides a subtle, savory kick that elevates the overall flavor profile. Now, it’s time to bring all the delicious components together: add the diced ham, the sautéed vegetables you prepared earlier, the refrigerated hash brown potatoes, and about 1½ cups of your freshly shredded Colby Jack cheese. Using a rubber spatula, gently fold all the ingredients together until they are well combined, ensuring an even distribution of all the savory bits throughout the egg mixture. Remember, freshly shredded cheese melts much more smoothly than pre-bagged varieties, contributing to a creamier texture.

Step 3: Bake Until Golden and Perfect

Carefully pour the entire egg and ingredient mixture into your prepared 9×13 inch baking pan, spreading it evenly. Once the mixture is settled, sprinkle the remaining ½ cup of freshly shredded Colby Jack cheese generously over the top of the casserole. This layer will create a beautiful golden-brown crust as it bakes. Transfer the pan to your preheated oven and bake for 35-40 minutes. The casserole is done when a knife or toothpick inserted into the center comes out clean, and the top is lightly golden brown and bubbly. Keep an eye on it to prevent over-browning, especially if your oven runs hot.

Step 4: Rest, Serve, and Enjoy!

Once baked to perfection, remove the casserole from the oven. While it might be tempting to dive right in, allow the casserole to rest for about 5-10 minutes before slicing. This crucial resting period allows the eggs to set properly, ensuring clean, intact slices that hold their shape. The internal temperature will also stabilize, making it easier and safer to handle. Slice into generous portions and serve warm. This casserole is not only a fantastic breakfast but also makes a delightful lunch or dinner, especially when paired with a fresh side salad. It’s truly a comfort food casserole that satisfies the heartiest of appetites any time of day!

Make-Ahead Tips, Customizations, and Storage Solutions

This casserole is a testament to versatility and convenience. Here are some extra tips to make it work even better for your lifestyle:

Cook’s Notes & Creative Substitutions

As mentioned earlier, feel absolutely free to customize this casserole to suit your taste and what you have in your pantry. It’s incredibly forgiving!

  • Vegetable Swaps: Instead of or in addition to mushrooms, onions, and green peppers, consider adding finely chopped spinach (sautéed and squeezed dry), diced zucchini, red bell peppers, or even a handful of frozen peas. Simply ensure any high-moisture vegetables are cooked down to prevent a watery casserole.
  • Protein Alternatives: If ham isn’t your preference, breakfast sausage is a fantastic substitute. Cook the sausage in a skillet until it’s no longer pink, crumble it, drain any excess fat, and then add it to the remaining ingredients. Cooked and crumbled bacon, diced turkey sausage, or even plant-based sausage crumbles can also be used. For a vegetarian option, consider adding black beans or extra hearty vegetables.
  • Cheese Varieties: While Colby Jack is excellent, feel free to experiment with sharp cheddar, Monterey Jack, Gruyere, or a Mexican blend. A touch of Parmesan can also add a salty, umami kick.
  • Spice It Up: Add a pinch of garlic powder, onion powder, smoked paprika, or a dash of your favorite hot sauce to the egg mixture for an extra layer of flavor. A sprinkle of fresh herbs like chives or parsley before serving can brighten the dish.

Make-Ahead Instructions for Busy Mornings

One of the best features of this breakfast casserole is its make-ahead potential:

  • Assemble the Night Before: Prepare the entire casserole up to the point of baking (Step 3). Cover the baking dish tightly with plastic wrap or aluminum foil and refrigerate overnight.
  • Baking from Cold: When ready to bake in the morning, remove the casserole from the refrigerator while your oven preheats. You may need to add an extra 5-10 minutes to the baking time since it’s starting cold. Ensure the center is completely set.

Storage and Reheating

Leftovers are just as delicious as the fresh bake, making this recipe perfect for meal prepping throughout the week:

  • Refrigeration: Store any leftover casserole in an airtight container in the refrigerator for up to 3-4 days.
  • Freezing: For longer storage, slice the cooled casserole into individual portions. Wrap each slice tightly in plastic wrap, then aluminum foil, and store in a freezer-safe bag or container for up to 2-3 months.
  • Reheating: Reheat individual slices in the microwave for 1-2 minutes or in a toaster oven at 350°F (175°C) for 10-15 minutes until heated through. If reheating from frozen, thaw overnight in the refrigerator first, or add extra time for frozen portions.

Frequently Asked Questions (FAQs)

Can I use frozen hash browns?

Yes, absolutely! If using frozen hash browns, it’s crucial to thaw them completely and then squeeze out as much excess moisture as possible. This prevents the casserole from becoming watery. You can wrap them in a clean kitchen towel or paper towels and press firmly.

My casserole is runny in the middle. What went wrong?

A runny casserole usually indicates it’s undercooked. Make sure your oven temperature is accurate and bake until a knife inserted into the center comes out clean. If the top is browning too quickly, you can loosely cover it with foil for the remaining baking time.

How can I prevent the casserole from drying out?

The heavy cream in this recipe helps keep the casserole moist. The main culprit for dryness is often overbaking. Start checking for doneness at the lower end of the suggested baking time and remove it from the oven as soon as the center is set.

We hope this comprehensive guide inspires you to create this incredible breakfast casserole for your family. May everyone have a fantastic and well-fueled school year!

Ingredients  

  • 2 Tbsp. olive oil
  • 8 oz. sliced white button mushrooms
  • 1 cup yellow onions, finely chopped
  • 1 cup green pepper, finely chopped
  • 12 large eggs
  • 1 cup heavy cream
  • 1 tsp. salt
  • 1 tsp. pepper
  • 1 1/2 Tbsp. prepared Dijon mustard
  • 1 8-oz. package diced ham
  • 2 cups freshly shredded Colby Jack cheese
  • 1 lb. package refrigerated hash brown potatoes

Instructions 

  • Preheat oven to 375 degrees Fahrenheit (190°C). Spray a 9×13 inch baking dish generously with nonstick spray and set aside.
  • In a large skillet, heat your 2 tablespoons of olive oil over medium-high heat. Add your sliced white button mushrooms and cook, stirring often, until they are nicely browned and have released their moisture, which takes about 5-6 minutes. Then, add your finely chopped onions and green peppers to the skillet and continue to cook for another 3-4 minutes until they are just slightly softened. Remove the skillet from the heat and set the cooked vegetables aside.
  • In a large mixing bowl, whisk your 12 large eggs until light and frothy. Then, add the heavy cream, Dijon mustard, salt, and pepper, whisking until well combined. Incorporate the diced ham, the sautéed vegetables, the refrigerated hash brown potatoes, and about 1½ cups of your freshly shredded Colby Jack cheese. Mix gently with a rubber spatula until all ingredients are evenly distributed throughout the egg mixture.
  • Pour the entire egg and ingredient mixture into your prepared 9×13 inch baking pan. Top the casserole evenly with the remaining ½ cup of cheese. Bake in the preheated oven for 35-40 minutes, or until a knife inserted into the center of the casserole comes out clean and the top is lightly golden brown. Allow to rest for 5-10 minutes before serving.

Notes

As mentioned above, feel free to substitute with any veggies you prefer, as well as the cheese. For frozen hash browns, ensure they are thawed and excess moisture is squeezed out before mixing.

I sometimes substitute the ham with breakfast sausage. If using breakfast sausage, cook it in a skillet until no longer pink and crumbled, then drain any excess fat before adding it to the remaining ingredients. This casserole can be assembled the night before and refrigerated; simply add 5-10 minutes to the baking time if baking from cold.
