Preheat your oven to 400°F (200°C).
In a large oven-safe skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant.
Season the salmon fillets with salt, pepper, Italian seasoning, and red pepper flakes (if using). Place the salmon skin-side down in the skillet. Cook for 3-4 minutes until the skin is crispy.
Carefully flip the salmon fillets and add the halved cherry tomatoes around them. Cook for another 2 minutes.
Pour in the heavy cream and chicken broth, then sprinkle the grated Parmesan cheese over the top.
Transfer the skillet to the preheated oven and bake for 10-12 minutes, or until the salmon is cooked through and flakes easily with a fork.
Remove from the oven and garnish with fresh basil before serving.
