Effortless to prepare and packed with flavor, it’s a one-pan wonder that will have everyone coming back for seconds.
Preheat your oven to 375°F (190°C). Place the pie crust into a 9-inch pie pan and crimp the edges if needed. Set aside.
Heat a skillet over medium heat and add the olive oil and butter. Once melted, add the frozen O’Brien potatoes and sauté for about 5–7 minutes until warmed through and lightly golden. Remove from heat and let cool slightly.
In a large mixing bowl, whisk the eggs until frothy. Add the heavy cream, salt, black pepper, garlic powder, and nutmeg. Whisk until well combined.
Spread the sautéed O’Brien potatoes evenly over the bottom of the prepared pie crust.
Sprinkle the shredded cheddar and Monterey Jack cheeses evenly over the potatoes.
Pour the egg and cream mixture over the potatoes and cheese. Gently stir or jiggle the pan to ensure the liquid fills all gaps.
Sprinkle the sliced scallions evenly over the top for added flavor and garnish.
Place the quiche on the middle rack of the preheated oven. Bake for 35–40 minutes, or until the center is just set and a knife inserted into the center comes out clean.
Remove the quiche from the oven and let it cool for 10–15 minutes before slicing and serving.
Serve warm, garnished with additional scallions if desired.
