Potato Crusted Spinach Quiche

It’s been two months since I posted a recipe.  Too many interesting research articles, bunnies, work…the list is endless.  Well the drought is over.  I had leftover mashed potatoes in the fridge and told myself “I am not going to waste perfectly fine leftover mashed potatoes”.  I hopped online to find  a decent potato pancake recipe.  But instead, I stumbled on a quiche recipe that used instant mashed potatoes for the crust.  One of my go to recipes is frittata that has plenty of potatoes in it.  So why not quiche?

Trigger Warning for Easily Offended Militant Vegans

Stop reading now.  This recipe has eggs and dairy.

You’ll need:

3 tablespoons EVO

2 tablespoons butter

2 cups leftover mashed potatoes

1 small (or half a large) sweet onion, chopped

2 cups frozen organic chopped spinach, thawed & drained

2 large mushrooms (white button or baby bella) sliced thin

4 large eggs

1 cup organic half and half

1 cup shredded sharp cheddar cheese cheese

1/4 cup grated Parmesan cheese

Two dashes nutmeg

salt & pepper

Directions

  1. Pre-heat oven to 350 degrees.
  2. Grease a 9″ pie pan with 1 T of the olive oil.  Press the mashed potatoes into the pie pan to form a crust.
  3. Bake the potato pie crust for 30 minutes.  After 30 minutes turn the oven off and leave the potato crust in the oven for another 15 minutes.  Remove from oven and set aside.  Cool thoroughly.
  4. Heat up the oven again, this time to 425 degrees.
  5. In a large pan saute onion and mushroom for approximately 10 minutes in 1T olive oil and 2T of butter.  Add defrosted and drained spinach and continue to saute until the mixture is somewhat dry.  Add a dash of nutmeg. You don’t want any visible liquid.  Set aside.  Cool thoroughly.
  6. In a small mixing bowl whisk the eggs & half and half.  Add the other dash of nutmeg, and a dash apiece of salt and pepper.
  7. Spread vegetable mixture evenly on your potato pie crust.
  8. Sprinkle Parmesan and cheddar cheeses over the spinach mixture.
  9. Pour egg mixture over the spinach and cheeses.
  10. Bake at 425 degrees for 15 minutes.  Turn oven heat down to 350 degrees and continue baking for approximately 30 more minutes or until golden brown.

Slice & serve.

 

Tips

Why yes, of course you can add cooked diced bacon at step 8.5.  Swiss instead of cheddar would be an excellent substitute.  If you don’t have any leftover mashed potatoes by all means use one of those deep dish frozen pie shells.  If you add bacon and use a frozen pie crust this recipe becomes my world famous spinach quiche that I’ve been making for years.  But as I move along the spectrum to more of a WFPB diet I’ve been leaving the bacon out.

I’m not quite sure how I would make this pie palatable for my easily offended militant vegan readers.  I need to think about this a little more.

Scalloped Potatoes

4 cups thinly sliced potatoes
Half cup diced sweet onion
Half stick butter
3 tablespoons flour
2 cups milk
Dash salt and pepper
2 cups grated sharp cheddar cheese, divided
4 slices American cheese

  1. Melt butter in a large saucepan over medium heat.  Saute onions until translucent.
  2. Add flour to create a roux.  Add milk slowly, stirring continuously.  Add salt, pepper, one cup of the cheddar cheese and all of the American cheese.  Simmer briefly until all of the cheeses have melted and you have a smooth sauce.  Remove from heat.
  3. Preheat oven to 350.
  4. Butter a baking dish large enough to hold the potatoes.  Alternate layers of potatoes and sauce, ending with a layer of sauce on top.
  5. Cover with aluminum foil and bake for 45 minutes.
  6. After 45 minutes, remove the aluminum foil and bake uncovered for another 45 minutes.
  7. During the last five minutes, sprinkle the remaining cup of cheddar cheese on top of the casserole.
  8. Remove from oven and let set for at least 15 minutes prior to serving.

 

Simple is good and super simple is better.  Recipes for Scalloped Potatoes are all pretty much the same.  Potatoes, butter, cheese, milk, bake.  But when you get compliments on the potatoes, you put the recipe on the blog to hopefully answer the question:

“So what do you do differently?”

After thinking about the question and  looking a few other recipes, the answer is not much.  (but I think it’s the half stick of butter).

TIPS – slice the potatoes as thin as possible, 1/4 inch is good.  Sauce up every layer of potatoes.  Use a high quality extra sharp cheddar cheese.  Butter, not margarine.
