Step‑by‑Step Instructions for Spiralized Sweet Potato Gluten-Free Breakfast Casserole Delight
Step 1: Prepare the Sausage
In a medium skillet over medium heat, crumble and cook the sweet Italian sausage for about 5-7 minutes, stirring occasionally until it’s thoroughly browned and no longer pink inside. Once cooked, drain excess fat and set the sausage aside on a plate, allowing it to cool while you prepare the sweet potatoes.
Step 2: Spiralize the Sweet Potato
Peel the sweet potato and using a spiralizer, create spirals until you have approximately 2 cups of sweet potato spirals. In a mixing bowl, toss these spirals with cornstarch until they are evenly coated, which will help bind them and give the dish great texture once baked in the Spiralized Sweet Potato Gluten-Free Breakfast Casserole.
Step 3: Mix the Casserole Ingredients
In a large bowl, whisk together the shredded cheese, eggs, milk, and salt until smooth and creamy. Next, fold in the cooked sausage along with the spiralized sweet potatoes, stirring until all ingredients are well combined and coated, creating a rich mixture that embodies the comforting flavors of the casserole.
Step 4: Prepare for Baking
Grease a 9″x13″ baking dish with cooking spray or olive oil to prevent sticking. Carefully pour the combined mixture into the prepared dish, spreading it out evenly. For the best results and enhanced flavors, cover the dish with plastic wrap and refrigerate overnight to allow the ingredients to meld beautifully.
Step 5: Bake the Casserole
The next day, preheat your oven to 375°F (190°C). Once the oven is ready, remove the casserole from the refrigerator and uncover it. Bake for 40-45 minutes, observing the dish as it cooks; the center should be set and no longer jiggle when gently shaken, indicating doneness.
Step 6: Cool and Serve
After baking, take the casserole out of the oven and let it cool slightly for about 10 minutes. This resting time will help firm up the casserole, making it easier to slice. Serve warm, and consider adding a splash of hot sauce or a dollop of sour cream for extra flavor!
