Heat the butter in an ovenproof pot over medium heat.
When the butter has melted, add the leeks and carrots, and sauté until the leeks have become tender.
Add the rice, and cook until the rice becomes shiny. Then add the stock.
Place a paper tent over the rice, place the lid on the pot, and bake for about 12 minutes.
Remove the rice from oven and allow it to rest for another 12 minutes.
Then remove the lid and paper tent, stir, and serve.

Recipe Tips
Pro Cooking Tips for Perfect Rice Pilaf
The Rinse is Non-Negotiable: Don't skip rinsing the rice. This removes the surface starch that would otherwise make your pilaf gummy instead of fluffy. Rinse until the water runs almost clear.
Watch Your Heat: When sautéing the rice in butter, maintain medium heat. Too hot, and the butter will burn; too low, and the rice won't get that crucial toasting that helps keep the grains separate.
The Parchment Paper Trick: The parchment paper lid (called a cartouche in professional kitchens) creates a microenvironment of perfect steam distribution. If you don't have parchment, aluminum foil shaped to fit works as a substitute.
