Ingredients You'll Need

The ingredients for this dish are wonderfully simple but each plays a crucial role in delivering a delicious result. From the creamy eggs and sweet potatoes to the aromatic herbs and savory sausage, everything blends together perfectly to create comfort in every bite.

• Avocado oil: a heart-healthy oil perfect for sautéing vegetables with a mild flavor.
• Yellow onion: adds a sweet and savory base to deepen the casserole’s flavor profile.
• Green bell pepper: brings a touch of freshness and subtle bitterness for balance.
• Cubed sweet potatoes: provide natural sweetness, color, and a creamy texture when baked.
• Garlic cloves: offer a warm, aromatic punch that every savory dish needs.
• Turkey sausage: a lean protein that adds robust flavor without excess fat.
• Eggs: the essential binder that creates the custardy structure.
• Milk: keeps the eggs tender and adds moisture; plant-based options work beautifully too.
• Dried thyme: infuses the dish with earthy, slightly floral notes.
• Salt and pepper: fundamental seasonings that bring all the flavors to life.
• Grated mozzarella cheese: melts to creamy perfection and adds gooey richness on top.

Directions

Step 1: Start by preheating your oven to 375°F (190°C) and lightly grease a casserole dish with a bit of avocado oil or nonstick spray to prevent sticking.

Step 2: Heat the avocado oil in a large skillet over medium heat. Add the chopped yellow onion and green bell pepper, cooking for about 5 minutes until they begin to soften and develop a sweet aroma.

Step 3: Toss in the cubed sweet potatoes and minced garlic. Sauté for another 8 to 10 minutes, stirring occasionally, until the sweet potatoes are tender but not mushy. This step builds a flavorful base for the casserole.

Step 4: Add the turkey sausage to the skillet, breaking it apart with your spoon or spatula. Cook until the sausage is browned thoroughly and cooked through, about 6 minutes. Drain any excess fat if necessary.

Step 5: In a large mixing bowl, whisk together the eggs, milk, dried thyme, salt, and pepper until well combined and frothy. This mixture will give your casserole its creamy egg texture.

Step 6: Transfer the cooked sausage and vegetable mixture into your prepared casserole dish. Pour the egg mixture evenly over the top, allowing it to settle between the ingredients.

Step 7: Sprinkle the grated mozzarella cheese generously across the surface. The cheese will melt and form a delicious golden crust while baking.

Step 8: Place the casserole in the preheated oven and bake for 30 to 35 minutes, or until the eggs are fully set and the cheese is bubbly and golden brown. A toothpick inserted into the center should come out clean.

Step 9: Remove the casserole from the oven and let it rest for 5 to 10 minutes before slicing. This resting time helps the custard set fully for perfect slices.

Servings and Timing

This Easy Sweet Potato Egg Casserole Recipe yields about 4 hearty servings, perfect for a small family or group. The prep time is approximately 15 minutes, which includes chopping and cooking the veggies and sausage. Baking takes about 30 to 35 minutes, and allowing 5 to 10 minutes for resting means you’ll have a delicious dish ready in just under an hour. Altogether, the total time is around 55 minutes, so it’s ideal for both relaxed weekends or busy days where you still want a nourishing meal without too much fuss.

How to Serve This Easy Sweet Potato Egg Casserole Recipe

I love serving this casserole warm, straight from the oven, so the cheesy top is still melty and the eggs are perfectly creamy. It pairs beautifully with a fresh green salad tossed with a light vinaigrette which cuts through the richness. Roasted cherry tomatoes or steamed asparagus also make excellent side dishes that add color and texture contrast.

For presentation, I often garnish it with a sprinkle of freshly chopped parsley or chives to add a burst of color and a touch of herbal brightness. You can slice it into individual squares or scoop it out in rustic portions—it looks inviting either way! I find that serving it on pretty plates with a side of crusty whole-grain bread completes the meal perfectly.

When it comes to beverages, this casserole works with a variety of choices. For brunch, a chilled mimosa or a light herbal tea feels just right. For dinner, try pairing it with a glass of medium-bodied white wine like a Sauvignon Blanc or a crisp sparkling water with lemon. It’s a dish that fits beautifully into family dinners, holiday gatherings, or casual get-togethers, making it versatile for many occasions.

Variations

One of the things I adore about this Easy Sweet Potato Egg Casserole Recipe is how easily adaptable it is. If you want to switch up the protein, ground chicken, pork sausage, or even a plant-based sausage alternative work wonderfully and keep the flavor rich. For a vegetarian version, you can simply omit the sausage and bump up the veggies or add cooked mushrooms for an earthy bite.

If you’re looking for dietary modifications, this casserole is naturally gluten-free since it relies on eggs and veggies. For a vegan twist, you can replace eggs with a chickpea flour batter or a tofu scramble base, and use vegan cheese and plant-based milk to keep that lovely creaminess. I’ve also experimented with adding spices like smoked paprika or cumin for a slightly different flavor dimension that adds warmth and complexity.

Additionally, you can cook the sweet potatoes ahead by roasting them instead of pan-sautéing, which gives a deeper caramelized flavor and can save you a step when assembling. Some days, I even bake the whole casserole in muffin tins for individual portions that make serving at brunches or parties super easy and fun.

Storage and Reheating

Storing Leftovers

Leftover casserole stores wonderfully in an airtight container in the refrigerator for up to 4 days. I prefer using glass containers with tight seals to maintain freshness and prevent any lingering odors. Before sealing, make sure the casserole is completely cooled to avoid condensation, which can make it soggy.

Freezing

This Easy Sweet Potato Egg Casserole Recipe freezes well too if you want to make it in advance or save leftovers for later. I recommend cutting the casserole into individual portions and wrapping each square tightly in plastic wrap before placing them in a freezer-safe zipped bag or container. This way, the pieces won’t freeze together, and you can thaw exactly what you need. The casserole will keep in the freezer for up to 2 months without losing flavor or texture.

Reheating

To reheat, I prefer warming single portions in the oven at 350°F (175°C) for about 15 minutes to restore the crispy cheese topping and creamy interior. A microwave works well in a pinch—heat in 30-second bursts until warmed through—but the texture is best preserved in the oven. Avoid overheating as it can dry out the eggs, so keep an eye on the casserole while reheating.

FAQs

Can I use regular pork sausage instead of turkey sausage?

Absolutely! Pork sausage works great and will add a little more richness to the dish. Just be mindful of the fat content—if it’s very fatty, you might want to drain some of the grease after cooking to keep the casserole balanced and not too oily.

Is this casserole suitable for meal prep?

Yes! It’s fantastic for meal prepping because you can make it ahead, refrigerate, and then reheat portions throughout the week. It reheats well and provides a nourishing, protein- and veggie-packed meal with minimal effort once cooked.

Can I substitute the mozzarella cheese with another type?

Definitely. Mild cheddar, Monterey Jack, or even feta cheese can be great alternatives. Each brings a slightly different flavor and texture, so feel free to experiment based on what you like or have on hand.

What can I serve with this casserole for a more complete meal?

I like pairing it with fresh greens such as arugula salad, roasted vegetables, or a simple fruit salad for a refreshing contrast. Adding a slice of whole-grain toast or a warm biscuit rounds out the meal nicely.

Can I make this casserole vegan?

Yes! To make it vegan, swap the eggs for a chickpea flour batter or blended silken tofu, use plant-based milk and vegan cheese, and replace the sausage with a plant-based alternative or extra vegetables. The texture and flavor won’t be exactly the same, but it’s still delicious and satisfying.
