Gluten-Free Hash Brown Quiche Recipe: Ingredients & Substitutions

• Frozen hash browns – convenient and naturally gluten-free. You can also grate and dry your own potatoes to make fresh hash browns.
• Butter – or substitute olive oil if preferred.
• Milk – whole or 2% works well; heavy cream or half-and-half will make a richer filling.
• Mustard – use your favorite variety for added tang.
• Bell peppers – swap in other vegetables such as broccoli, zucchini, cauliflower, carrots, spinach, or asparagus.
• Cheddar cheese – any melty cheese will work.
• Bacon – optional. Omit for a vegetarian version and sauté the vegetables in 2 tablespoons olive oil instead. If you omit bacon, you may want to adjust salt to taste. You can also substitute ham, breakfast sausage, or another preferred meat.

How to Make Hash Brown Quiche

The recipe is straightforward: bake the hash brown crust first, prepare the filling while the crust bakes, then pour, top, and bake until set. The steps below outline the full process.

Make the Hash Brown Crust

Preheat the oven to 400°F (205°C). Grease a 9-inch round pie plate.

In a bowl, combine 15 ounces frozen hash browns, 2 tablespoons melted salted butter (or olive oil), 1/2 teaspoon sea salt, and 1/4 teaspoon pepper. Mix until combined.

Press the mixture firmly into the prepared pie plate, covering the bottom and up the sides. Bake for 10 minutes. If using frozen hash browns that are not thawed, remove after 10 minutes and press the crust firmly into the pan with the back of a spoon to seal any gaps. Return to the oven and bake an additional 20–25 minutes (about 30–35 minutes total) until the crust is just beginning to brown. Set aside.

Make the Filling

Reduce the oven temperature to 350°F (175°C). In a sauté pan over medium-high heat, cook 4 slices diced bacon until it starts to brown and render fat. Add 1 tablespoon minced garlic, 1/2 cup diced onion (optional), 1 green bell pepper (finely diced), and 1 red bell pepper (finely diced). Cook until the vegetables are soft and the bacon is browned, about 4–5 minutes. If skipping bacon, sauté the vegetables in 2 tablespoons olive oil or butter. Set the cooked vegetables aside to cool slightly.

In a large bowl whisk together 6 large eggs, 1/2 cup milk, 1 tablespoon mustard, 1/2 teaspoon fine sea salt, 1/4 teaspoon pepper, and 1/4 teaspoon paprika. Stir in 1 cup shredded cheddar cheese, then fold in the cooked vegetable and bacon mixture.

Pour the filling into the prepared hash brown crust. If desired, top with thin slices of 1 medium tomato.

Bake

Bake at 350°F (175°C) for 35–45 minutes, or until the filling is set and the top is golden brown. Remove from the oven and let cool for at least 15 minutes before slicing. The quiche can be served warm or cold.

Serve

Allow the quiche to rest for 15 minutes, then slice and serve slightly warm. It pairs well with roasted potatoes, a simple fruit salad, or warm bread for a more substantial meal. For a sweet-and-savory breakfast, serve alongside cinnamon rolls or banana bread.

Store & Freeze

Store leftovers in an airtight container in the refrigerator for up to five days. Freeze portions for up to two months. Reheat gently in the oven or microwave until warmed through.
