Why I Love This Breakfast Casserole
I’m a big fan of meals that do double duty, and this one absolutely does. It’s:
- Easy to prep ahead
- Packed with protein
- Loaded with veggies
- Flexible with ingredients
- Kid-approved (always a win)
Using Greek yogurt instead of heavy cream keeps it lighter while still creamy, and the combination of eggs, sausage, and hash browns makes it filling enough to power you through the morning. This is one of those recipes that proves healthy food doesn’t have to be boring.
💡 Ingredient flexibility:
This recipe is forgiving. Swap the meat, change the veggies, or adjust the cheese — it’s hard to mess this one up.
Ingredients
Equipment
Method
- Smash and finely chop the garlic. Dice the bell peppers and onion, then slice the Roma tomato. Set aside.
- In a large bowl, whisk the eggs with black pepper, sea salt, and paprika. Add the Greek yogurt and whisk until smooth and fully combined.
- Toss in the garlic, bell peppers, onion, tomato, and shredded cheese
- Preheat oven to 350°F. Grease a 9×13-inch baking dish with avocado oil or preferred cooking spray.
- Spread hash browns evenly in the bottom of the baking dish. Layer the unccooked sausage over the hash browns
- Pour the egg mixture evenly over the casserole, ensuring it fills all gaps.
- Bake uncovered for 60 minutes, or until the eggs are set, the top is lightly golden, and the center no longer jiggles.
- Remove from the oven and let rest for 5 minutes before slicing and serving.

Frequently Asked Questions
Can I freeze this breakfast casserole?
Yes! Let it cool completely, slice it, and freeze individual portions. Reheat straight from frozen or thaw overnight.
Can I make this the night before?
Absolutely. Assemble everything, cover, and refrigerate overnight. Bake fresh in the morning.
Can I use milk instead of Greek yogurt?
You can, but Greek yogurt adds more protein and creaminess. Sour cream also works if you prefer.
How do I know it’s fully cooked?
Insert a knife into the center — if it comes out clean and the casserole doesn’t jiggle, it’s ready.
