Prep Your Leeks: First things first, wash those leeks thoroughly. Chop off the dark green parts and slice the white and light green sections into thin rounds.

Cook the Leeks: Heat up your butter and olive oil in a skillet over medium heat. Add the leeks and cook until they’re soft and slightly golden, about 8-10 minutes.

Add the Cream: Pour in the heavy cream and stir it in. Let it simmer gently for a few minutes until it thickens.

Cheese Time: Now comes the fun part – add your grated cheese and stir until it melts beautifully into the creamy mixture. Season with salt, pepper, and garlic powder if you like.

Garnish and Serve: Sprinkle some fresh thyme on top and voila! Your cheesy leeks are ready to be devoured.
