Tuscan Baked Salmon with Brown-Buttered Tomatoes & Basil is a simple and elegant dish that features salmon fillets roasted in the oven and topped with a delicious sauce made with butter, tomatoes, and basil.
Position the salmon on a baking dish or quarter sheet pan, skin side down. Season with salt and pepper to your liking.
Heat a medium saucepan over medium heat, then add the butter. Swirl the pan gently until the butter turns nutty and brown, approximately 3 to 4 minutes. Adjust the heat as needed, and when it begins to smell like popcorn, you're nearing the ideal stage.
Stir in red wine vinegar, red pepper flakes to taste, and cherry tomatoes (ensure they are dry if recently washed to avoid butter splatter). Season with salt and cook for an additional 2 to 3 minutes until the tomatoes burst, releasing their juices.
Smash them gently with a wooden spoon to create a sauce.
Drizzle the salmon with the brown butter and tomatoes, ensuring even coverage over the fish. Bake until the flesh is flaky and cooked, approximately 10-15 minutes, depending on the size of the fish (or until an instant-read thermometer reads 120 degrees in the thickest part).
Allow the salmon to cool briefly, then sprinkle basil over it. When ready to serve, break the salmon into large chunks and distribute them among the plates, accompanied by cherry tomatoes cooked in brown butter. Add a sprinkle of flaky sea salt to taste.
Garnish the dish with fresh basil leaves and serve it with lemon wedges, crusty bread, pasta or rice, or salad.
Notes
Keep an eye on your fish, every oven, and every piece of fish cook a little different. A few minutes can be the difference between perfection, and sadness. Better to error on the side of undercooked.
