The Best in and out sauce recipe
What really sells this recipe for me is how easy it is to adapt. We’ve made it with chicken, shrimp, or even just plain pasta on busy nights, and it always hits the spot. My husband and I have even used it as a dip for fries or veggies when we’re in a rush, and it’s always a hit. Plus, it’s got health benefits too—it’s got protein if you’re using meat, and it’s got fiber if you’re adding veggies. It’s not some heavy, greasy dish, but it still tastes like a little indulgence. And honestly? That’s all some people need sometimes. It’s the kind of dish that feels like a little celebration, whether it’s a family dinner or just a lazy Sunday night.

❓ Frequently Asked Questions About In-N-Out Burger-Inspired In-and-Out Sauce
What is the primary ingredient in the classic In-N-Out Burger In and Out Sauce?
The primary ingredient in the In-NOut Burger In and Out Sauce is tomato paste, which forms the base of the rich, tangy sauce. It’s blended with other key components like ketchup, mustard, onions, and sometimes a touch of vinegar or Worcestershire sauce for depth.
—
Can I make the In-NOut In and Out Sauce at home without using a specific recipe?
While In-NOut’s exact recipe is proprietary, you can closely replicate it at home by combining 1 cup tomato paste, ½ cup ketchup, 2 tbsp yellow mustard, 1 tbsp onion powder (or finely chopped onions), 1 tsp garlic powder, 1 tsp Worcestershire sauce, 1 tsp vinegar (apple or white), and a pinch of salt. Adjust seasoning to taste—some add a splash of hot sauce or a bit more mustard for extra tang.
—
Why does In-NOut’s sauce have that signature thick, chunky texture?
The thick, chunky texture comes from thickening agents like tomato paste and finely processed onions (or onion powder), which break down into a smooth yet slightly grainy consistency. In-NOut’s method traditionally involves blending the ingredients until they reach a smooth but slightly textured mouthfeel—some even add a small amount of cornstarch or flour to further thicken it. The sauce is never completely silky like store-bought versions.
—
Is there a vegetarian or vegan version of In-NOut’s In and Out Sauce?
Yes! To make a vegetarian or vegan version, skip the Worcestershire sauce (which contains anchovies) and replace it with soy sauce or a plant-based Worcestershire alternative. Use tomato paste, ketchup, vegan mustard, onion powder, apple cider vinegar, and a pinch of salt. Some also add a dash of vegan Worcestershire or smoked paprika for depth. Avoid meat-based ingredients like bacon bits or beef broth in the sauce itself.
—
How do I store homemade In-NOut In and Out Sauce for later use?
Store homemade In and Out Sauce in an airtight container in the fridge for up to 5–7 days. For longer storage, freeze it in portion-sized containers (like ice cube trays for small servings) and use within 3 months. Thaw in the fridge before reheating—it works best when gently warmed on low heat (avoid boiling to preserve texture).
