Preheat oven to 425F and line a large baking sheet with parchment paper. Set aside.
Whisk together the 1 cup ricotta cheese and the 1 large egg in a small bowl, and season lightly with salt and pepper. Set aside.
Thinly slice the 1/2 onion and add it to a small mixing bowl.
Peel the 3 medium carrots and then, with your vegetable peeler, shred the rest of the carrot into thin ribbons. Add to the bowl with the onion.
Add the 3 Tbsp sliced almonds to the carrots and onions, and season everything with olive oil, salt, and pepper. (Note: carrots can vary a lot, you are aiming for about 4 very loosely packed cups of carrot ribbon and sliced onion mixture to top this tart. A little bit more or less is fine.)
Place the thawed puff pastry on your lined baking sheet. Using a sharp knife, score around the outer edges of the puff pastry about 3/4 inch in from the edge.
Spread the ricotta filling evenly over the inside area of the puff pastry.
Top with the carrot and onion mixture. It will be loose and "airy", no need to pack it down before cooking.
Drizzle with a little more olive oil and the 1/2 tsp honey.
Bake for 20-25 minutes until the puff pastry is risen and golden brown.
Remove and allow to cool briefly before serving. Garnish with parsley if desired.
