Riviera Hashbrown Quiche
Sister Sue, Sandwich Week, and a Quiche to Remember
Twice a year, my sister Sue comes to visit—and when she does, it’s always a delicious occasion. But this visit wasn’t just about spoiling her with gourmet dinners. This time, Sue was here for Sandwich Week prep—seven days, seven sandwiches—for the next broadcast of A Seasoned Friendship, the podcast I co-host with Lori Bregenzer.
Still, even a sandwich-centric week needs some breakfast brilliance. I had to serve up a few standout morning meals—something warm, comforting, and maybe even brand new. I gave Sue a few options and let her choose. She picked a dish originally titled: Green Olive and Artichoke Quiche.
Let’s just say, I took some liberties.
Making It My Own (Because Of Course I Did)
The original recipe came from Mezzetta, the same folks who make many of the olives, peppers, and jarred goods you might use in a recipe like this. But it read more like a product showcase than something you’d crave on a chilly morning.
So I got to work turning it into something we would love.
Flavored Hashbrown Crust? Yes, Please.
First off, the hashbrown crust. It called for just shredded potatoes and cheese. No salt. No seasoning. Nothing. I had one word: Why?
I upgraded the crust with garlic powder, onion powder, salt, and pepper—the way we season our hashbrowns at breakfast. It added the savory punch the base was desperately missing.
A Pepperoni Twist
Next up: the meat. The original called for cubed sopressata or salami. Now, I love Italian food as much as anyone, but cubes of spicy meat at brunch? A bit much—especially for Sue.
So I went with sliced and chopped pepperoni, offering just the right amount of heat and richness in a bite-sized format. Every slice of quiche had the perfect balance of spice and flavor, without overpowering the delicate custard.
The Olive MVP
Now let’s talk olives. This is where the recipe made a genuinely smart call: Castelvetrano olives. If you’ve never had them, you’re in for a treat. These aren’t your typical pimento-stuffed green olives. Castelvetranos are buttery, mild, slightly crisp, and meaty. They brought brightness, body, and a touch of elegance to every bite.
Tips for Assembly (and Avoiding Overflow)
When pouring the custard into the pan, it’ll look like too much. The hashbrown crust is thick and not the most giving in terms of space. But trust me—pour slowly. The milk and eggs will find their way into the little gaps between the potatoes.
Layer your ingredients thoughtfully, so you don’t end up with a single mouthful of artichoke or olive. Balance is key.
⚠️ Pro tip: Place a sheet pan or tray under your pie dish in case the filling puffs up and spills. You don’t want that mess in your oven.
The Final (and Most Important) Step: Let It Rest
Once the quiche comes out of the oven, resist the urge to dive in right away. Let it rest. Let it cool. This helps the custard set beautifully, ensuring a clean, showstopping slice when you serve.
Sister-Approved, Mom-Endorsed
The result? Sister Sue was delighted. My mom gave it her seal of approval. And I added a new brunch favorite to my ever-growing rotation.
It was warm, flavorful, and beautifully layered—just like the stories we share on the podcast. Bon Appétit!

This Is Delicious! What Is It?
Riviera Hashbrown Quiche
Sun-kissed flavors from the Mediterranean coast: briny olives, tender artichokes, and spiced pepperoni in a savory custard, all baked into a hashbrown shell.

Ingredients
- 4 cups hash browns, frozen, shredded, thawed
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon ground black pepper
- 1/2 cup shredded mozzarella cheese
- 6 large eggs
- 1 cup whole milk
- 1 cup pepperoni slices, cut crosswise
- 1/2 cup marinated artichoke hearts, drained and chopped
- 1/2 cup green olives, Castelvetrano, sliced
- 1 cup shredded mozzarella cheese
- salt and pepper, to taste
Instructions
- Preheat your oven to 400°F and spray a 9-inch pie dish with non-stick cooking spray.
- Squeeze as much liquid as you can from the thawed hash browns and transfer to a large mixing bowl.
- Add 1/2 a cup of shredded mozzarella cheese, onion and garlic powders, salt and pepper and combine well.
- Transfer the mixture to the greased pie dish and press the hash browns into an even layer and up the sides of the dish. Transfer to the oven to bake for 15-20 minutes. You want the edges to be slightly browned and the middle to feel like it has a bite to it but not be brown.
- While the crust is cooking, in a large bowl, whisk together the eggs, milk and salt and pepper to taste.
- Remove the pie dish from the oven and add 1/2 a cup of shredded mozzarella to the bottom of the crust, half of the pepperoni, half of the chopped artichoke hearts and half of the sliced olives.
- Pour in the egg mixture and top with the remaining pepperoni, artichoke hearts, sliced olives, chives, and remaining mozzarella. The pie pan will be very full.
- Make sure you have a tray underneath the pie pan in the oven to catch drippings. Transfer to the oven.
- Bake for 30 minutes. Open oven and turn pie pan 90 degrees and close oven door. Turn temperature down to 375 and bake another 15-20 minutes until the center of the quiche is set. Top of quiche should be evenly browned.
- Remove the quiche from the oven and allow it to cool for 10 minutes before slicing and serving.
