So, expressing how thrilled I am to finally share this recipe with all of you is a significant understatement.

Ingredient Spotlight: Fueling Your Day with Flavor
This casserole comes fully loaded with diced, crisp-tender sweet potato hash browns, providing sustained energy and hunger control. It also features colorful bell peppers (or capsicums), earthy sliced mushrooms, nutrient-rich sautéed spinach, and sweet cherry or grape tomatoes to brighten every bite. A light dusting of shredded mozzarella cheese adds a touch of creamy indulgence, while crumbled sausage boosts the protein content, ensuring you stay full and satisfied. But, as fantastic as this combination is, the true beauty of this recipe lies in its incredible versatility.
Customization is Key!
Don’t fancy bell peppers? Simply leave them out! Not a fan of sausage? Feel free to swap it for crispy bacon, diced ham, or even shredded chicken. For a delicious vegetarian option, omit the meat entirely and perhaps add some black beans or a handful of crumbled feta cheese for extra flavor. The possibilities are endless, making this recipe truly adaptable to your taste, dietary preferences, or whatever ingredients you have on hand. Consider adding:
- Different Vegetables: Sliced zucchini, diced eggplant, corn kernels, broccoli florets, kale, or even asparagus can be wonderful additions. Think seasonally!
- More Proteins: Cooked ground beef, turkey, or even a plant-based crumble can replace or supplement the sausage.
- Cheese Varieties: Cheddar, Monterey Jack, Gruyere, or a spicy pepper jack would all be fantastic alternatives to mozzarella.
- Spice & Herbs: A pinch of red pepper flakes for heat, or fresh herbs like chives, parsley, or cilantro for a fresh finish.


Simple Steps for a Perfect Breakfast Casserole
Preparing this hearty casserole is surprisingly straightforward, ensuring a delicious outcome every time. The key is in a few simple steps:
Step 1: Prepare Your Baking Dish
First, you need to lightly grease a 9×13-inch casserole dish. A quick spray of cooking oil or a thin coating of olive oil will do the trick. This crucial step guarantees that your casserole won’t stick to the pan, allowing you to serve beautiful, clean slices rather than an unsightly “mountain of egg mess.” This also makes cleanup significantly easier.
Step 2: Cook Your Components in Order
To achieve optimal textures and flavors, we cook the ingredients in a specific sequence. Begin by frying your sweet potato hash until it’s crisp on the outside and tender within. Next, cook your chosen sausage meat, breaking it up as it browns. Finally, sauté your vegetables until they reach your desired tenderness. This methodical approach ensures that each element contributes its best to the overall dish.
Step 3: Assemble and Egg Wash
Once cooked, dump all the prepared ingredients – the sweet potatoes, sausage, and sautéed vegetables – into your greased casserole dish, as shown in the images above ↑. In a separate bowl, whisk together the eggs with milk, half of your shredded cheese, and season generously with salt and pepper. This egg mixture will bind all the ingredients together and provide that fluffy, savory base.
Step 4: Pour and Top
Carefully pour the egg mixture evenly over all the ingredients in the casserole dish. Ensure it seeps down and coats everything for a cohesive bake. Afterwards, sprinkle the remaining shredded cheese over the top, creating a golden, bubbly crust when baked. A final dash of salt and pepper over the top layer of cheese will enhance the flavors even further. Observe the beauty of this step ↓


Bake to Perfection & Enjoy!
And that’s it! Once assembled, pop your casserole into the oven for approximately 45 minutes. You’ll know it’s ready when it’s beautifully cooked through, golden brown, and delightfully crisp around the edges. What emerges is a perfect, cheesy Sweet Potato Hash Brown Breakfast Casserole that everyone at your table will absolutely adore! It’s truly ideal for a hearty breakfast, a leisurely brunch, or those wonderfully lazy weekend mornings when staying in your pajamas is the only agenda.

Make-Ahead Magic: Prepare Today, Enjoy Tomorrow
One of the best features of this sweet potato breakfast casserole is its make-ahead potential. You can assemble the entire casserole the night before, cover it tightly with plastic wrap, and refrigerate it. On the morning you plan to bake, simply remove it from the fridge and allow it to come to room temperature for about 30 minutes before placing it in the oven. This little trick ensures even cooking and frees up your morning for more important things, like enjoying your coffee!
Serving Suggestions & Pairings
While this casserole is hearty enough on its own, it can be elevated with a few simple additions. Consider serving it with:
- A dollop of sour cream or Greek yogurt.
- Fresh avocado slices or a generous scoop of guacamole.
- Your favorite salsa or a dash of hot sauce for an extra kick.
- A sprinkle of fresh chopped cilantro, chives, or green onions.
- A simple side salad for a complete brunch experience.
