I made these for the first time because I had half a block of feta sitting in my fridge that wasn’t going to last much longer, and somehow they became the thing I make more than almost anything else. Twelve triangles, one toaster oven, under 40 minutes start to finish. Phyllo can feel intimidating but it’s genuinely forgiving once you stop worrying about it — a tear here or there disappears under the butter and the heat.
If you’ve got a decent toaster oven baking sheet with a rim, you’ll be in great shape. That rim matters because melted butter has a way of going rogue. The convection setting, if your machine has one, gets these extra crispy on all sides — but regular bake at 400°F works totally fine too.
The lemon herb dipping oil is optional in the sense that you could technically skip it, but I really wouldn’t. It takes two minutes to stir together and it makes the whole thing feel like something you’d order at a restaurant. Fresh parsley, good olive oil, lemon zest. Simple. The feta inside is already salty and rich, so the brightness from the lemon is exactly what it needs.
These work as an appetizer, a snack, or honestly a light dinner if you throw together a quick salad. I’ve brought them to potlucks packed in a container and reheated them in whatever toaster oven was available — they always disappear. If you don’t already have a reliable toaster oven that can hit a consistent 400°F, this recipe is a good reason to find one you trust.
Toaster Oven Crispy Feta and Spinach Phyllo Triangles with Lemon Herb Dipping Oil
Flaky, golden phyllo triangles stuffed with salty feta and wilted spinach, baked right in your toaster oven until shatteringly crisp. They come together faster than you'd think and disappear even faster.
Ingredients
Phyllo Triangles
Lemon Herb Dipping Oil
Instructions
Make the Filling
-
Heat a small skillet over medium heat and add the spinach with a splash of water. Cook, stirring, for about 2 minutes until wilted. Transfer to a clean kitchen towel or several layers of paper towels and squeeze out as much liquid as you possibly can. Seriously, don't skip this — wet spinach is the enemy of crispy phyllo.
-
In a bowl, combine the squeezed spinach, crumbled feta, beaten egg, minced garlic, black pepper, and nutmeg. Mix it together well and set aside.
Form the Triangles
-
Preheat your toaster oven to 400°F on the bake or convection bake setting. Line your toaster oven baking tray with parchment paper.
-
Lay one sheet of phyllo on a clean, flat surface and brush it lightly with melted butter. Lay a second sheet directly on top and brush again. Cut the double-layered sheet lengthwise into 3 even strips — you should have 3 long rectangles.
-
Place a heaping tablespoon of filling at the bottom corner of each strip. Fold the corner up and over the filling diagonally to form a triangle. Keep folding — just like folding a flag — up the length of the strip until you reach the end. Brush the outside lightly with butter and place seam-side down on your prepared pan. Repeat with the remaining phyllo sheets and filling. You should end up with about 12 triangles total.
Bake
-
Slide the pan into your toaster oven and bake for 15 to 18 minutes, until the triangles are deep golden brown and visibly crispy. Every toaster oven runs a little differently, so start checking at 15 minutes. They should sound hollow when you tap them lightly.
-
While they bake, whisk together the olive oil, lemon juice, lemon zest, parsley, oregano, red pepper flakes, and flaky salt in a small bowl. That's your dipping oil.
-
Let the triangles cool for 3 or 4 minutes before serving — the filling holds heat like crazy. Serve warm with the dipping oil alongside.
Notes
Phyllo dries out fast. Keep sheets you're not actively working with covered with a lightly damp towel — not wet, just damp. If your triangles are browning too fast on top before the bottom crisps, move the rack down one position. Leftovers reheat really well in the toaster oven at 375°F for 5 to 6 minutes; skip the microwave unless you enjoy sad, soggy pastry. You can assemble these up to a day ahead and refrigerate them unbaked on the parchment-lined tray covered loosely with plastic wrap. Add 2 or 3 minutes to the bake time if going straight from cold.
