Season the salmon
Pat salmon dry. Coat with Cajun seasoning, salt, and pepper.
Cook the salmon
Heat olive oil in a skillet over medium-high heat. Cook salmon for 4–5 minutes per side until golden and cooked through. Remove and set aside.
Make the sauce
In the same skillet, add garlic and cook for 30 seconds. Pour in chicken broth and stir. Add heavy cream and paprika. Let it simmer until slightly thick.
Combine everything
Add lemon juice. Return salmon to the skillet. Spoon sauce over the top.
Finish and serve
Sprinkle parsley and add lemon slices. Serve warm.
