Preheat your oven to 425°F (220°C).
Line a baking sheet with parchment paper. Cut the white potato into small cubes for crispiness.
In a bowl, toss the potato cubes with 1 teaspoon of olive oil, salt, pepper, and a pinch of dried thyme.
Spread the potatoes on one side of the baking sheet and roast in the oven for about 20-25 minutes, stirring halfway through for even crisping.
While the potatoes start roasting, prepare the salmon. Pat the salmon dry with a paper towel.
Mix the minced garlic, dried thyme, dried rosemary, a pinch of salt, and pepper in a small bowl. Rub this herb mixture evenly over the salmon fillet.
Drizzle the salmon with the remaining olive oil.
After the potatoes have been roasting for about 10 minutes, add the asparagus to the baking sheet. Toss the asparagus lightly with a little salt, pepper, and a drizzle of olive oil if desired.
Place the salmon fillet on the baking sheet beside the vegetables. Continue roasting everything together for an additional 12-15 minutes, or until the salmon is cooked through and flaky, the potatoes are crispy, and the asparagus is tender.
Remove the tray from the oven, plate your salmon, potatoes, and asparagus. Enjoy your balanced, nutrient-packed meal!
