The Ingredients You’ll Need

Here’s what goes into this delicious, wholesome bake—and why each ingredient matters:

• Sweet potatoes: The star of the show. They add a subtle sweetness and creamy texture that balance out the savory sausage and eggs.
• Turkey sausage: Lean, flavorful, and full of protein. It’s what makes this casserole taste like breakfast in a bite.
• Eggs: The glue that holds it all together—literally and figuratively. Eggs make this one of the easiest Eggs For Dinner Recipes Healthy enough to double as breakfast.
• Bell pepper & onion: For a pop of color and freshness. They add natural sweetness and crunch.
• Garlic: Because everything’s better with a little garlic kick.
• Mozzarella cheese: It melts beautifully, giving you that gooey, creamy goodness in every bite.
• Thyme: A touch of herbiness that ties everything together.
• Milk: Helps create a fluffy, custard-like texture. Whole milk adds richness, but any milk works.
• Avocado oil: Keeps everything cooking evenly while adding healthy fats.

Pro Tip: Cut your sweet potatoes into ½-inch cubes. Any bigger, and they won’t cook evenly; any smaller, and they’ll get mushy before the eggs set.

How to Make This Sweet Potato Egg Casserole

Step 1: Preheat and Prep

Set your oven to 350°F (175°C). Grease a 9×13-inch casserole dish with oil or nonstick spray—because nothing ruins a good breakfast like scrubbing baked-on eggs.

Chop your veggies (sweet potatoes, onions, peppers) into even pieces so they cook at the same rate.

Step 2: Cook the Veggies

In a large skillet or Dutch oven, heat your oil over medium heat. Toss in your onions, bell pepper, and sweet potatoes. Sauté for about 8–9 minutes until they begin to soften and get a little color.

Right before you’re done, add the garlic—just long enough for that irresistible aroma to hit. Then transfer everything into your greased casserole dish and spread it out evenly.

Pro Tip: Don’t overcrowd the pan while sautéing. You want a bit of browning, not steaming—that’s where the flavor comes from!

Step 3: Brown the Sausage

In the same pan, cook your turkey sausage, breaking it into bite-sized bits as it cooks. Once it’s nicely browned and no longer pink, add it to your casserole dish and mix it with the veggies.

Step 4: Whisk the Eggs

In a medium bowl, crack in your eggs and whisk until smooth. Add the milk, thyme, salt, pepper, and cheese. Mix until everything looks rich and creamy.

Step 5: Combine and Bake

Pour your egg mixture over the veggies and sausage, giving everything a gentle stir to make sure the eggs reach every corner. Bake uncovered for 40–45 minutes, until the center feels firm and the top is golden.

If the top starts browning too fast, cover it loosely with foil to keep things from getting crispy.

Step 6: Cool and Serve

Let your casserole rest for 10–15 minutes before slicing. This helps the eggs set completely and makes it easier to cut neat squares.

The Story Behind This Recipe

This dish actually came about by accident. One busy weeknight, I had leftover roasted sweet potatoes from dinner, a few eggs nearing expiration, and some turkey sausage sitting in the fridge. I threw everything into a baking dish, crossed my fingers, and baked it. The result? Absolute magic.

That’s when I realized this wasn’t just a lazy dinner experiment—it was a legit Breakfast For Dinner Ideas Healthy kind of recipe. Since then, I’ve made it for everything from brunch gatherings to cozy holiday mornings. It’s that versatile.

Pro Tips for the Best Results

• Uniform cubes = even cooking: Keep your sweet potato pieces around ½ inch for the perfect texture.
• Drain any liquid: After cooking sausage and veggies, remove excess grease or moisture. This keeps the casserole from turning soggy.
• Let it rest: Don’t cut it straight from the oven! A 10-minute rest gives you cleaner slices and better texture.
• Use room temp eggs: They mix more evenly and bake fluffier.
• Customize your veggies: Mushrooms, spinach, or even zucchini can sneak in extra nutrients.
