Preheat oven to 200 degrees Celsius (400 degrees Fahrenheit).
Rinse basmati rice under cold water until the water runs clear, then place in a pot with vegetable stock and a pinch of salt.
Bring rice to a boil, then reduce heat to low, cover, and simmer for 15-18 minutes until tender.
Place salmon fillets on a parchment-lined baking sheet and drizzle with olive oil.
Season salmon with minced garlic, lemon zest, salt, and pepper, placing lemon slices on top of each fillet.
Bake salmon in the preheated oven for 12-15 minutes or until the internal temperature reaches 63 degrees Celsius (145 degrees Fahrenheit).
Once rice is cooked, fluff with a fork and fold in the finely chopped fresh dill.
Serve the baked salmon over the dill-infused rice.
