I’ve spent years perfecting this copycat version of that famous secret menu spread. This recipe delivers the same creamy, tangy flavor you love without leaving home.
The balance of sweet and savory comes from a simple blend of mayonnaise, ketchup, and a few key seasonings. It’s the perfect topping for burgers, fries, or sandwiches.
Ingredients for In and Out Animal Sauce
A handful of pantry staples creates this iconic creamy, tangy spread everyone craves.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥫 | ½ cup | Full-fat for creaminess |
| Ketchup 🍅 | ¼ cup | Classic American style |
| Yellow Mustard 🟡 | 2 tbsp | Smooth, not whole grain |
| Sweet Relish 🥒 | 2 tbsp | Fine chop preferred |
| White Vinegar 💧 | 1 tsp | Balances sweetness |
| Granulated Sugar 🍚 | 1 tsp | Dissolves easily |
| Garlic Powder 🧄 | ½ tsp | Not garlic salt |
| Onion Powder 🧅 | ½ tsp | Fine grind preferred |
| Paprika 🌶️ | ¼ tsp | Sweet or smoked variety |
| Salt 🧂 | ¼ tsp | Fine grain preferred |
The mayonnaise is the base here—Duke’s or Hellmann’s give that classic richness. Ketchup should be a trusted brand like Heinz for consistent flavor. I grab my mustard from French’s (the classic yellow bottle). For relish, Vlasic or Heinz sweet relish works perfectly. Don’t skip the vinegar—it cuts through the sweetness beautifully.
No sweet relish? Diced bread and butter pickles work in a pinch. Out of yellow mustard? Dijon at half the amount adds a nice kick. Want it sweeter? Add another half teaspoon of sugar. Prefer more tang? A splash of pickle juice from the jar does wonders. The spices can be adjusted to taste—this sauce is forgiving.
Stays fresh in the fridge for about 1 week in an airtight container. The flavors meld after a day, so it tastes even better. Perfect for burgers, fries, or as a dip—I always make a double batch.

Step-by-Step Instructions for Animal Sauce
Here’s the method. Straightforward, tested, works every time.
Step 1: Combine the Base Ingredients
In a medium bowl, add the 0.5 cup Mayonnaise and 0.25 cup Ketchup. I like to use full-fat mayonnaise here—it creates that signature creamy texture that makes this sauce so addictive.
Whisk these two together until the mixture turns a uniform light orange color with no visible streaks. This is your foundation. The mayonnaise provides the rich, velvety base while the ketchup adds that classic tangy sweetness.
Step 2: Incorporate the Tangy and Sweet Elements
Add the 2 tbsp Yellow Mustard, 2 tbsp Sweet Relish, 1 tsp White Vinegar, and 1 tsp Granulated Sugar to the bowl. The relish should be finely chopped for the best texture—you want those tiny bits of pickle distributed evenly throughout the sauce.
Mix thoroughly for about 1-2 minutes until everything is fully combined. The mustard adds a sharp tang, the relish brings sweetness and a subtle crunch, while the vinegar and sugar work together to balance the flavors perfectly.
Step 3: Season for Depth of Flavor
Now stir in the 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, 0.25 tsp Paprika, and 0.25 tsp Salt. I always add these last to ensure they’re evenly distributed throughout the sauce.
The garlic and onion powders deepen the savory profile, while the paprika adds a hint of smokiness. Taste the sauce at this point—you’re looking for a balanced flavor that’s tangy, slightly sweet, and undeniably rich. If it needs adjustment, you can add a pinch more salt or sugar, but I’ve found these proportions hit the mark every time.
Step 4: Chill for Optimal Flavor and Consistency
Transfer the sauce to an airtight container and refrigerate for at least 30 minutes. This chilling time allows the flavors to meld together and the sauce to thicken slightly, making it easier to spread.
I’ve found that the sauce tastes even better after 24 hours in the fridge, as the flavors continue to develop. The texture should be smooth, creamy, and spreadable—perfect for burgers, fries, or as a dip. Give it a good stir before using, as some separation may occur during storage.
Pro Tips For Making In And Out Animal Sauce
- Chill the Sauce: After mixing, refrigerate the animal sauce for at least 30 minutes—this lets the flavors meld and thickens it slightly, just like the real deal.
- Drain the Relish: Press the sweet relish in a fine-mesh strainer for 10 seconds to remove excess liquid, or your sauce will be watery instead of creamy.
- Skip the Sweet Swap: I learned this the hard way—using regular dill relish instead of sweet throws off the balance and makes it taste more like tartar sauce than animal sauce.
- Start with Mayo: Mix the mayonnaise first before adding other ingredients—it creates a smooth base and prevents the vinegar from curdling the sauce.
Health Benefits of in and out animal sauce
Healthy Fats Source
The mayonnaise base provides healthy monounsaturated fats that support heart health. These fats help your body absorb fat-soluble vitamins like A, D, E, and K from other foods in your meal. I use full-fat for creaminess and these nutritional benefits. 💪
Low-Calorie Option
At about 90 calories per tablespoon, this sauce lets you enjoy rich flavor without excessive calories. The vinegar and mustard add tang without significant calories, making it a smarter choice than many store-bought sauces loaded with sugar.
Antioxidant Boost
Both paprika and garlic powder contain antioxidants that combat inflammation. Paprika, especially the smoked variety, is rich in capsaicin, which may boost metabolism. These spices add flavor and health benefits.
No Artificial Additives
Unlike many commercial sauces, this homemade version contains no preservatives or artificial flavors. You control the ingredients, ensuring a cleaner product. The white vinegar acts as a natural preservative while enhancing flavor.
Balanced Flavor Profile
The combination of sweet, tangy, and savory elements means you can use less sauce to satisfy your taste buds. This can lead to reduced overall sugar and sodium intake compared to heavier condiments. I find it enhances meals without overpowering them.
Quick Energy Source
The granulated sugar provides a quick energy boost, while the fats from mayonnaise offer sustained energy. This makes the sauce a great addition to post-workout meals or snacks when you need a pick-me-up. 💛
