Why You’ll Love This Flavorful Cajun Garlic Butter Sauce

This sauce is magic in a skillet. You’ll love it because it’s insanely versatile—a drizzle transforms grilled shrimp into a Cajun feast or a bowl of rice into something craveable. It’s spicy, but not overwhelming, buttery but not greasy, and filled with warm, garlicky comfort. Best of all, you can whip it up with pantry staples.

Can I Use Salted or Unsalted Butter for Cajun Sauce?

Both will work, but unsalted butter gives you more control over the saltiness of the sauce. Since Cajun seasoning blends already contain salt, starting with unsalted butter prevents the flavor from getting too intense. If you’re using salted butter, you may want to skip adding extra salt until the end, after tasting.
