Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 medium thinly sliced yellow onion and cook for 8-10 minutes, stirring occasionally, until caramelized and golden brown.
  2. Step 2: Add 3 minced garlic cloves and 6 cups roughly chopped fresh spinach to the onions and sauté for 3-4 minutes until the spinach wilts and releases moisture. Season with 1/2 tsp salt, 1/4 tsp black pepper, and 1/8 tsp red pepper flakes if using.
  3. Step 3: Roll out 2 thawed puff pastry sheets on a baking sheet lined with parchment paper. Using a knife, score a 1-inch border around each sheet without cutting all the way through.
  4. Step 4: Divide the spinach mixture evenly between the two pastry sheets, spreading within the scored border. Sprinkle 6 oz crumbled feta cheese evenly over the spinach.
  5. Step 5: Brush the borders of the pastry with 1 beaten egg to help with browning. Bake for 20-25 minutes until the pastry is puffed and golden brown.
  6. Step 6: Let cool for 5 minutes before slicing into squares and serving warm.

How do I store leftover Spinach and Feta Puff Pastry Tart?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep olive oil from drying out.

Can I substitute ingredients in Spinach and Feta Puff Pastry Tart?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Spinach and Feta Puff Pastry Tart for a different number of people?

The recipe is written for 6 servings. Multiply each ingredient by (your serving target / 6). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

Is Spinach and Feta Puff Pastry Tart vegetarian?

Yes — this recipe is tagged vegetarian based on its ingredient list. Always cross-check labels for packaged ingredients (sauces, broths, condiments) since formulations vary by brand.
