In a small bowl, add the soy, minced garlic, ginger, lemon, and honey, then whisk.
Add the salmon filet (I used wild sockeye salmon) on a prepared baking sheet with parchment paper, then spray the whole salmon with cooking spray.
Pour half of the marinade on the salmon, garnish with fresh rosemary then fold in the parchment paper from left and right and allow for salmon to soak in the marinade for about 5 minutes.
Open parchment paper, then bake salmon at 450F for 15 minutes.
Pour the other half of the sauce into a small saucepan, add the cornstarch, turn the heat on high, and whisk until it comes to a boil and has sauce has thickened.
Once the salmon is finished, pour the thickened sauce all over the cooked salmon and enjoy with a side of mashed potatoes and steamed broccoli. You can also garnish some black sesame seeds, rosemary, or green onion on top of the salmon fillets.
