How to Make Sweet Potato Breakfast Casserole: An Incredible Ultimate Recipe
Step 1: Roast the Sweet Potatoes
Begin by preheating your oven to 375°F (190°C). Peel and dice the sweet potatoes, then spread them on a baking sheet. Drizzle with olive oil and toss until they’re evenly coated. Pop them in the oven and roast for 20 minutes, or until the sweet potatoes are fork-tender and lightly caramelized. This first step unlocks their natural sweetness, laying the perfect base for your Sweet Potato Breakfast Casserole: An Incredible Ultimate Recipe.
Step 2: Brown the Sausage
While your sweet potatoes work their magic in the oven, heat a skillet over medium heat. Add your ground sausage—whether you opt for pork, turkey, or a plant-based alternative—and cook it thoroughly, crumbling as it sizzles. Once browned and cooked through, transfer the sausage to a separate plate to cool slightly. This savory element infuses the casserole with classic breakfast flavor in every bite.
Step 3: Sauté the Aromatics and Veggies
Don’t wipe out the skillet! Use any remaining flavorful drippings to sauté your diced onion and both bell peppers for about 5–6 minutes. When they’re soft and starting to turn golden, stir in the minced garlic, smoked paprika, thyme, salt, and black pepper. Give it all one more minute on the heat to release the aromatics. This veggie mixture sneaks in color, crunch, and layers of flavor.
Step 4: Whisk Up the Eggs and Milk
In a large bowl, crack those eggs and add your milk of choice. Whisk them together until fully combined and slightly frothy—this mixture is the glue that holds the casserole together and delivers that signature fluffy texture.
Step 5: Combine Everything
Now comes the beautiful part: fold the roasted sweet potatoes, cooked sausage, and sautéed veggies into your egg mixture. Add both shredded cheddar and mozzarella cheeses, reserving a little extra for sprinkling on top if you’re feeling extra decadent. Stir until evenly incorporated. This step ensures every forkful of Sweet Potato Breakfast Casserole: An Incredible Ultimate Recipe is hearty, cheesy, and full of flavor.
Step 6: Bake the Casserole
Pour your mixture into the prepared 9×13-inch baking dish, smoothing out the top for an even bake. Place the dish in your preheated oven and bake for 30–35 minutes, or until the eggs are fully set, and the top is irresistibly golden and bubbling. Let the casserole cool for a few minutes before adding the final touches or slicing to serve.
