Make the Fries:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Potatoes: Peel and cut the russet potatoes into thick fries. Make sure they are evenly sized for consistent cooking.
3. Season the Fries: Toss the fries in vegetable oil, salt, and pepper. Lay them in a single layer on a baking sheet.
4. Bake the Fries: Bake in the preheated oven for 25-30 minutes, flipping halfway through, until golden and crispy.

Prepare the Gravy:

5. Cook the Onion: In a medium saucepan, melt butter over medium heat. Add the finely chopped onion and cook for 2-3 minutes, until softened and translucent.
6. Make a Roux: Sprinkle the flour over the cooked onions, stirring constantly for 1-2 minutes to form a roux. This helps thicken the gravy.
7. Add the Broth: Gradually add the beef or chicken broth while stirring to avoid lumps. Bring to a simmer and cook for 5-7 minutes, until the gravy thickens.
8. Season the Gravy: Stir in the Worcestershire sauce and soy sauce, and season with salt and pepper to taste. Continue to simmer until the gravy is smooth and thick.

Assemble the Poutine:

9. Layer the Fries: Once the fries are done, transfer them to a serving dish or plate in an even layer.
10. Top with Gravy: Pour the hot gravy over the fries, making sure they are well-coated.
11. Add the Cheese Curds: Scatter the cheese curds generously over the fries and gravy, allowing the heat to melt the curds slightly.
12. Garnish and Serve: Optionally, garnish with fresh parsley for a touch of color. Serve immediately while the cheese is melty and the fries are still crispy.
