Step-by-Step Guide to Your Perfect Casserole
1. Browning the Sausage for Savory Depth
Our culinary journey begins by browning the sausage. I opted for mild Italian sausage, which offers a lovely, balanced flavor that appeals to most palates. However, feel free to personalize this step! If you prefer a kick, a hot Italian sausage would add a wonderful spicy note to the casserole. Break the sausage apart as it cooks, ensuring it browns evenly and develops a rich, savory depth that will permeate the entire dish. Don’t worry about any leftover grease in the pan – it’s going to add extra flavor to our next ingredient!

2. Sautéing the Butternut Squash and Wilting the Spinach
Once the sausage is browned and set aside, we’ll utilize the flavorful drippings left in the skillet. Add a small amount of unsalted butter to the pan, then introduce the star: Mann’s Culinary Cuts Butternut Squash Zig Zags. Sauté them for approximately 5 minutes, allowing them to begin to soften and develop a slight caramelization. To ensure they reach the perfect tender consistency, add about 1/2 cup of water to the pan. Don’t fret, the water will evaporate as the squash continues to cook, leaving behind perfectly tender and subtly sweet pieces.

Once the butternut squash has reached your desired tenderness, it’s time to incorporate the vibrant baby spinach. Initially, it might seem like an overwhelming amount of spinach for the pan, but watch as it quickly wilts down into a manageable and delicious portion. At this stage, the fragrant combination of savory sausage remnants, sweet squash, and earthy spinach is incredibly tempting – a note for future meals, this mixture alone makes an excellent side dish for chicken or beef!

3. Crafting the Creamy Egg Mixture
The eggs are the binding force that brings all these wonderful ingredients together into a cohesive and satisfying casserole. You’ll need a full dozen large eggs to ensure a rich and fluffy texture throughout the dish. In a large mixing bowl, whisk these eggs thoroughly with half-and-half cream. The cream adds a luscious richness and helps create that melt-in-your-mouth consistency that makes breakfast casseroles so irresistible. This combination will form the custardy base of our breakfast delight.

To further enhance the flavor and add a pop of color, stir in freshly diced tomatoes and vibrant sliced green onions. These fresh additions provide a welcome burst of freshness and texture. Season the entire egg mixture with aromatic garlic powder and earthy dried oregano, along with a touch of salt. These spices will perfectly complement the savory sausage and sweet butternut squash, creating a harmonious flavor profile.

4. Assembling the Casserole Layers
Now, it’s time to bring all of our delicious components together! Start by adding the browned sausage to your egg mixture. Ensure it’s evenly distributed so every bite of the casserole includes that wonderful savory flavor.

Next, carefully fold in the sautéed butternut squash zig zags and wilted spinach. Gently mix everything until the ingredients are well combined within the egg mixture. This creates a vibrant and texture-rich base for our casserole.

5. The Grand Finale: Cheese and Baking to Perfection
To finish, generously sprinkle a layer of shredded cheddar cheese over the top of the casserole mixture. This cheese will melt into a golden, gooey crust during baking, adding another layer of irresistible flavor and texture. This is also the ideal moment to prepare the casserole for an overnight stay in the fridge if you’re planning ahead. Simply cover the dish tightly and refrigerate until the next morning. However, if you’re like me and can’t resist, proceed to bake it immediately!

Bake the casserole in a preheated oven for approximately 40 to 50 minutes. Baking times can vary slightly depending on your oven, so keep an eye on it. You’ll know it’s perfectly done when the cheesy topping is beautifully golden brown, and the eggs are fully set and cooked through. A knife inserted into the center should come out clean.

Once out of the oven, allow the casserole to cool for about 15 minutes before serving. This crucial resting period not only prevents you from burning your mouth but also allows the casserole to firm up slightly, making for cleaner, more presentable slices.


Serving Your Holiday Breakfast Masterpiece
Cut the casserole into generous, large pieces and serve immediately. You can proudly call this a “loaded breakfast casserole” because it’s truly packed with an abundance of delicious ingredients. Each forkful delivers the creamy goodness of the eggs, the satisfying pull of melted cheddar cheese, the savory punch of spicy (or mild) sausage, and the perfectly sweet and tender butternut squash zig zags. The combination is simply irresistible and incredibly fulfilling. It’s a symphony of textures and flavors that will start any day, especially a holiday, on a high note.


Leftovers and Long-Lasting Flavor
Should you be lucky enough to have any leftovers, rest assured that this casserole tastes just as fantastic the next day! Simply heat individual portions in the microwave for a quick and satisfying meal. This recipe has quickly become a recurring favorite in my household, and I eagerly anticipate preparing it again and again, especially when my extended family gathers for holiday celebrations. It’s a dish that truly keeps on giving, making busy mornings a little more delicious even days after preparation.

I sincerely hope you’ll give this sausage and butternut squash breakfast casserole a try during the upcoming holidays. It’s a hearty, flavorful, and surprisingly easy way to feed a crowd or simply enjoy a special morning. I’d absolutely love to hear about your experience – how it turned out, and what you thought of the wonderful Culinary Cuts Butternut Squash Zig Zags!

1 hour 10 minutes
Ingredients
- 1 package Mann’s Culinary Cuts Butternut Squash Zig Zags 284g/10oz package
- 6 mild Italian sausages casings removed
- 1 tsp unsalted butter
- ½ cup water
- 3 cups baby spinach
- 12 large eggs
- 1 cup half and half cream
- 2 tomatoes diced
- 2 green onions sliced
- ½ tsp dried oregano
- ½ tsp garlic powder
- ½ tsp salt
- 2 cups cheddar cheese shredded
Instructions
-
Preheat oven to 400°F (200°C). Lightly grease a 9-inch square casserole dish and set aside.
-
Heat a large skillet over medium-high heat. Cook the Italian sausage, stirring frequently and breaking it into crumbles, for about 6 to 7 minutes, or until fully cooked through. Once cooked, transfer the sausage to a plate lined with paper towels to absorb excess grease. Leave any remaining drippings in the pan for the next step.
-
In the same skillet, melt 1 teaspoon of unsalted butter over medium-high heat. Add the Mann’s Culinary Cuts Butternut Squash Zig Zags and sauté for 5 minutes. Stir in ½ cup of water and continue to cook until the squash is tender. Add the baby spinach and cook for another 3 to 4 minutes, until it has completely wilted. Remove the skillet from the heat.
-
In a large mixing bowl, whisk together the 12 large eggs and 1 cup of half-and-half cream until well combined. Stir in the diced tomatoes, sliced green onions, dried oregano, garlic powder, salt, and 1 cup of shredded cheddar cheese. Add the cooked sausage and the butternut squash and spinach mixture to the egg mixture, then stir gently until all ingredients are evenly distributed.
-
Pour the entire mixture into the prepared casserole dish. If making ahead, cover and refrigerate overnight. If baking immediately, sprinkle the remaining 1 cup of cheddar cheese over the top. Bake for 40 to 50 minutes, or until the eggs are completely set, and the topping is golden brown and bubbly.
-
Allow the casserole to cool for about 15 minutes before slicing and serving. This resting time helps the casserole to firm up, making it easier to cut and preventing it from being too hot. Enjoy your delicious, hearty breakfast!
