Step‑by‑Step Instructions for Blooming Onion Sauce
Step 1: Combine Ingredients
In a medium bowl, start by adding 1 cup of mayonnaise and ¼ cup of ketchup as your base for the Blooming Onion Sauce. Follow this by incorporating 2 tablespoons of prepared horseradish sauce, 1 teaspoon of granulated garlic, 1 teaspoon of smoked paprika, and ½ teaspoon of ground cumin. Finally, add ½ teaspoon of dried oregano, a pinch of kosher salt, and a dash of black pepper.
Step 2: Mix Smoothly
Using a whisk or spatula, mix all the ingredients together until the mixture is creamy and well-blended. Aim for a smooth consistency with no lumps remaining, which should take about 1-2 minutes of whisking. Take a moment to admire the vibrant color of your Blooming Onion Sauce as the spices blend seamlessly with the creamy base.
Step 3: Chill for Flavor
Cover the bowl with plastic wrap or transfer the sauce to an airtight container. Chill it in the refrigerator for at least 30 minutes. This resting period is crucial as it allows the flavors to meld beautifully, resulting in a richer, more harmonious tasting sauce.
Step 4: Serve and Enjoy
Once chilled, give your Blooming Onion Sauce a gentle stir, then serve it alongside crispy fried foods like onion rings, French fries, or chicken strips. The creamy tanginess and subtle kick will elevate your appetizers, making every dip a delightful experience.

Blooming Onion Sauce Recipe FAQs
How do I select the best ingredients for my Blooming Onion Sauce?
Absolutely! For mayonnaise, aim for a brand that’s creamy and rich for the best base. Regarding the horseradish, check for freshness—it should smell pungent but not overwhelming. When choosing paprika, opt for smoked paprika for that extra depth, unless you prefer it milder, in which case, regular paprika will do just fine.
How should I store Blooming Onion Sauce?
I recommend storing your Blooming Onion Sauce in an airtight container in the refrigerator. It will stay fresh for up to 2 weeks, so feel free to prepare it ahead of time for parties or whenever the craving strikes. Just ensure it’s well-sealed to maintain that delightful creamy texture.
Can I freeze Blooming Onion Sauce?
While I wouldn’t recommend freezing due to the mayonnaise base—it can separate and lose quality—you can still freeze it if absolutely necessary. Use a freezer-safe container and it should last for up to 3 months. When you’re ready to enjoy it, thaw it in the fridge, giving it a good stir before serving to restore its texture.
What if my Blooming Onion Sauce is too thick?
No worries! If you find your sauce is thicker than you’d like, just add a small amount of milk or cream to loosen it up. Stir in one tablespoon at a time until you reach your desired consistency. It’s all about achieving that perfect dip!
Are there any dietary considerations I should be aware of?
Yes! This Blooming Onion Sauce is naturally gluten-free, making it a suitable option for those with gluten sensitivities. If you’re making it for guests with allergies, you can easily swap mayonnaise for a vegan alternative or Greek yogurt for a lighter touch. Always check ingredient labels for allergens that may affect your guests.
Can my pets have any of the ingredients in Blooming Onion Sauce?
While it’s tempting to share, be cautious! Ingredients like onion and garlic can be harmful to pets. I recommend keeping this delicious Blooming Onion Sauce strictly for human enjoyment to ensure your furry friends stay safe!
