Alright, let's whip up a batch of that creamy, tangy, slightly spicy sauce that makes the Outback Bloomin' Onion so darn addictive! This is my version of the copycat recipe, and I think it captures the flavor profile perfectly.
Copycat Outback Bloomin' Onion Sauce
Yields: Approximately 1 cup Prep time: 5 minutes Chill time: At least 30 minutes (longer is better)
Ingredients:
- 1/2 cup mayonnaise (full-fat for best flavor and texture)
- 2 tablespoons ketchup
- 1 1/2 tablespoons horseradish (prepared, not creamy)
- 1 teaspoon paprika (smoked paprika adds a nice depth)
- 1 teaspoon dried oregano
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon cayenne pepper (adjust to your spice preference)
- 1/4 teaspoon black pepper
- 1 tablespoon whole milk or buttermilk (buttermilk will give it a nice tang)
- 1 teaspoon Worcestershire sauce
- Pinch of salt (taste and adjust after chilling)
Equipment:
- Medium mixing bowl
- Whisk or fork
- Airtight container for storage
Instructions:
- Combine Ingredients: In the mixing bowl, add the mayonnaise, ketchup, horseradish, paprika, oregano, garlic powder, onion powder, cayenne pepper, and black pepper.
- Whisk Together: Whisk the ingredients together until well combined and smooth.
- Thin and Flavor: Add the milk or buttermilk and Worcestershire sauce. Whisk again until fully incorporated. This thins the sauce to the desired consistency and adds more flavor.
- Taste and Adjust: Give the sauce a taste. Add a pinch of salt if needed. Remember, flavors will meld and deepen as it chills. If you want more heat, add a tiny pinch more cayenne. If you prefer a tangier taste, add a tiny squeeze of lemon juice or a dash more horseradish.
- Chill Thoroughly: Transfer the sauce to an airtight container. Refrigerate for at least 30 minutes, but ideally for 1-2 hours, or even overnight. This allows the flavors to meld and develop.
Chef's Notes & Tips:
- Spice Level: The 1/4 teaspoon of cayenne provides a mild heat. If you like it spicier, gradually add more until you reach your desired level.
- Horseradish Strength: The strength of prepared horseradish can vary. Start with the recommended amount and adjust to taste.
- Mayonnaise Matters: Full-fat mayonnaise is key to achieving the right texture and richness. Do not substitute with light or fat-free mayo.
- Consistency: If the sauce is too thick after chilling, add a tiny bit more milk or buttermilk to reach your preferred dipping consistency.
- Storage: The sauce will keep in an airtight container in the refrigerator for up to 5 days.
- Serving Suggestions: Obviously, it's fantastic with a Bloomin' Onion! But don't stop there. It's also delicious with:
- French fries
- Sweet potato fries
- Onion rings
- Grilled chicken or burgers
- As a dip for vegetables
Enjoy your homemade Bloomin' Onion sauce! This is one recipe where a little patience while chilling pays off big time in flavor. Bon appétit!
