Spinach Phyllo Triangles

Spinach Phyllo Triangles.  Glorious buttery crispy pockets of cheesy spinachy love.

This was the first dish I learned to make using phyllo dough.  There was some trial and error as I recall, but now this dish is quite routine for me.  While it does take a little more time to prepare than some appetizers, it is well worth it.  And your guests will love them too.

I’ll do my best to share the tips I’ve learned from working with phyllo dough and give you some step-by-step photos of how to make Spinach Phyllo Triangles.

Tip ~ Always gather all ingredients and have them ready to go into your recipe.  In this case thaw and drain spinach, mince onion, grind breadcrumbs, shred cheeses, etc.  There are two rolls of phyllo sheets per box.  You’ll only need one roll for this recipe.  Thaw one and leave the other in the freezer for the next time.

Step #1 ~ Sauté onion in butter until tender.  Add in spinach.

Step #3 ~ Stir until cheeses are melted and mixture is incorporated.  Reserve.

Step #4 ~ Cut sheets of thawed phyllo dough lengthwise into 3 rows 3-inches wide.

Tip ~ Keep remaining rows covered with a dish towel.  This keeps the dough from drying out.

Step #5 ~ Working with one row at a time, brush top strip with melted butter.

Tip ~ Use just enough butter to lightly coat each strip.  Otherwise they’ll get soggy making them difficult to fold.

Step #6~ Place 2 teaspoons of spinach mixture at the bottom corner of the top strip.

Step #7 ~ Fold the right bottom corner of the top strip over to form a triangle.  Continue folding back and forth as shown below.

Step #8 ~ Once completely folded place seam side down onto ungreased baking sheet.  Brush top with melted butter.  Repeat procedure with remaining phyllo strips, melted butter, and spinach mixture.

Step #9 ~ Bake at 325 degrees for 30 to 35 minutes.  Drain on paper towels.

Tip ~ Or once folded, cover baking sheet with plastic wrap and refrigerate until ready to bake, up to 2 days ahead of time.

Step #10 ~ Enjoy!

You can prepare Spinach Phyllo Triangles ahead of time, I made mine the day before.  Just wait to bake them until just before serving.

You can use this same method and change the filling to say a cheesy crabmeat mixture or perhaps a sausage cheese combo.  Once you get the hang of folding them what you stuff them with is your chance to get creative.  You know we love that!
