Prepare your ingredients by gathering all components: salmon fillets, garlic, cherry tomatoes, spinach, heavy cream, chicken broth, Parmesan cheese, Italian seasoning, salt, and pepper.

Heat a large skillet over medium-high heat and add a splash of olive oil, allowing it to heat until shimmering.

Season the salmon fillets with salt and pepper, then cook in the skillet for 4-5 minutes on each side until golden brown and flaky.

In the same skillet, sauté minced garlic for about 1 minute until fragrant, then add cherry tomatoes and cook for 2-3 minutes.

Add fresh spinach and cook until wilted, about 1-2 minutes, mixing well.

Pour in heavy cream and chicken broth, then add Parmesan cheese and Italian seasoning, stirring until the sauce simmers for 2-3 minutes.

Return the cooked salmon to the skillet, spooning the creamy sauce over it, and let it simmer for an additional 2-3 minutes.

Serve hot, optionally garnished with fresh basil.
