Originally I’d planned on making a quiche from either Vegan Brunch (Classic Broccoli!) or Betty Goes Vegan (Quiche Lorraine!) to represent the letter Q – and then Shane brought home a ginormous, 3-pound bag of hash browns. (I needed one whole cup for another recipe. Yeah.) With freezer space at a premium, I got the idea of making a quiche with a hash brown crust. So I hit the internet and, lo and behold: it’s been done before. Yay!
This recipe is a mashup of the hash brown quiche recipes found online and a Spinach Mushroom Quiche I made for VeganMoFo last year. Because I have a slightly oversized pie plate – 10″ versus the standard 9″ – I increased the amount of hash browns used from three to four cups, and added an extra teaspoon each of margarine and olive oil. If you have a smaller pie plate, just use three cups hash browns and two tablespoons each of margarine and olive oil. The salt is optional, but tasty. I like my potatoes with a little sodium, you know?
For what it’s worth, I don’t think I’ll ever make a quiche with a traditional crust again. The hash browns are the perfect complement to the quiche’s egg-like filling. It’s basically the fanciest means of eating breakfast foods for dinner. Universally recognized as a mature and responsible adult, yo.
Hash Brown Quiche
4 cups hash browns
2 tablespoons + 1 teaspoon margarine
2 tablespoons + 1 teaspoon olive oil
1/2 teaspoon salt
1 tablespoon olive oil
1/2 onion, diced
2 tablespoons minced garlic
1/2 cup mushrooms, sliced
1 red bell pepper, roasted and diced
1/2 cup frozen spinach, thawed, diced, and pressed to remove excess moisture
1 pound firm tofu
1/2 cup plain nondairy milk
1/3 cup nutritional yeast
2 tablespoons Dijon mustard
2 teaspoons chives
1/2 teaspoon garlic powder
1/2 teaspoon salt
1/2 cup shredded vegan cheese (optional; I used cheddar Daiya)
1-2 Roma tomatoes, sliced
vegan parmesan cheese to taste (optional; see recipe here)
1. Preheat the oven to 450F.
2. In a medium-sized bowl, combine the hash browns, margarine, olive oil, and salt; mix well. Grease a 10″ pie plate. Transfer the potato mix into the pie plate and press down firmly, on the bottom and sides, until you have an even “crust.” Bake at 450F for 25 to 30 minutes, or until the potatoes start to turn golden.
(Pro tip: if the top of the crust isn’t browning fast enough, set the oven to broil and leave it in for an extra minute or two. Be careful not to burn the sides, though! But if you do, just cover them up with the quiche filling; no one needs to know!)
3. As the crust is baking, prepare the filling. Heat the oil in a skillet over medium heat and cook the onions until soft and translucent. Add the minced garlic and mushrooms and continue to cook on medium heat until the mushrooms are browned to your liking. Stir frequently. Season with salt and pepper if desired.
4. In a food processor, combine the tofu, nondairy milk, nutritional yeast, mustard, chives, garlic powder, and salt. Process until smooth. Sample the batter and add any extra seasonings to taste.
5. In a large bowl, fold together tofu, mushrooms, spinach, red peppers, and cheese (optional). Pour the mixture into the pie crust; top with the tomato slices and a bit of vegan parmesan cheese if desired.
6. Bake at 375F for about 45 minutes, or until the quiche is firm and lightly browned. Allow to cool slightly before serving.
