Creating Spring Vegetable Pot Pie can be effortless if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Sauté Aromatics: In a large skillet, heat olive oil over medium heat. Add diced onion and minced garlic, sautéing until translucent.
3. Add Vegetables: Stir in diced carrots and asparagus. Cook for about 5 minutes until they start to soften.
4. Incorporate Remaining Vegetables: Add the peas and diced potato to the mixture. Stir together for another 2 minutes.
5. Add Liquid: Pour in the vegetable broth and heavy cream. Sprinkle thyme, rosemary, salt, and pepper. Mix well to combine.
6. Thicken Mixture: If desired, mix cornstarch with a little cold water and add it to the pot. Stir until the mixture thickens, about 2-3 minutes.
7. Prepare Pie Dish: Pour the vegetable filling into a pie dish and spread it out evenly.
8. Top with Crust: Place the pre-made pie crust over the vegetable filling. Crimp the edges to seal and cut a few slits on top for steam to escape.
9. Bake: Place the pie dish in the preheated oven and bake for 30-35 minutes until the crust is golden brown.
10. Cool and Serve: Remove from the oven and let it cool for a few minutes before serving.
