Cooking Steps
Adjust rack to top position and preheat oven to 400 degrees. Wash and dry produce.
Quarter potatoes lengthwise, then slice into ¼-inch-thick pieces.
Place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 10-12 minutes. Drain and set aside.
While potatoes cook, halve, peel, and thinly slice onion.
Heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add onion; cook, stirring occasionally, until browned and softened, 8-10 minutes.
Add spinach, Fry Seasoning, 1 tsp sugar (2 tsp for 12 servings) and a splash of water to pan with onion.
Cook until spinach is wilted and onion is caramelized, 2-3 minutes more.
Remove pan from heat. Stir in 1 TBSP butter (2 TBSP for 12) until melted; season with salt and pepper.
In a large bowl, whisk together sour cream, ¼ cup water, ¾ tsp salt, and pepper until well combined (½ cup water and 1½ tsp salt for 12 servings).
Whisk in eggs* until completely incorporated, 1-2 minutes. Wash and dry whisk (you’ll use it again in Step 6).
Stir in drained potatoes, spinach and onion mixture, and Italian cheese blend. (It’s OK if the veggies are still hot!)
Coat an 8-by-8-inch baking dish (9-by-13-inch baking dish for 12 servings) with nonstick cooking spray.
Pour egg mixture into prepared baking dish and evenly top with pepper jack.
Bake on top rack until eggs are set and cooked through and cheese is lightly browned, 20-25 minutes.
While frittata bakes, in a small bowl, whisk together sun-dried tomato paste and mayonnaise until smooth.
Cover with plastic wrap and refrigerate until ready to serve.
Let frittata cool for 5 minutes, then cut into 6 pieces (12 pieces for 12 servings).
To serve: Divide frittata between plates and serve with aioli on the side.
To stash: Let frittata cool completely. Refrigerate frittata and aioli in separate airtight containers for up to 3 days. Reheat in the microwave for 1-2 minutes.

Reviews from our home cooks
Delicious and easy to make! Love the sun dried tomato mayo and the choice of cheeses. I would probably add some sautéed mushrooms if I get it again.
A new easier method for doing a frittata and I will make it again. I didn't like the time it took me to make it, but I will plan better the next time.
F A N T A S T I C !!!!!!!!!!!!!! Very similar to the Starbuck's egg-n-potato bites. I made a copycat of that dish and it required the potatoes to be roasted first to provide a crust to the quiche. But this was great as well. LOVED IT!!!!!!!!!
The quality of the eggs and spinach were amazing. We loved this one.
This was our first time with this recipe & it won't be our last. There was plenty for a second meal, and it was delicious!
Very nice brunch dish. Better than the restaurant due to creaminess. Will make this again and vary the veggies.
Wanted something different, and this was it! Made this for dinner with one of your kale salads, and my husband and daughter loved it. Would definitely make again!
I loved this and having something made ahead that we could reheat.
Simple and fun to make. My gripe is that the sauce is kinda weird. I don't know what about it is weird, but it doesn't really pair well with the frittata (in my opinion). Tbh I think it'd taste better with a tomato salsa or a side of fruits.
Good but not a ton of flavor. I would figure out something else to add to the egg casserole in the future to give it a little more flavor. The aïoli really added.
