Why I Like This Recipe
This sauce? It’s my go-to when I’m not trying to make a whole thing. I just want a little something extra to dip into — fries, onion rings, even warm bread if I’m desperate. Toss everything in a bowl, stir, chill. It’s always good, always reliable, and honestly kinda grounding.
Ingredients
- ½ cup full-fat mayonnaise
- 2 teaspoons ketchup
- 2 tablespoons prepared horseradish
- ¼ teaspoon paprika
- ¼ teaspoon salt
- ⅛ teaspoon garlic powder
- ⅛ teaspoon dried oregano
- Dash of black pepper
- Dash of cayenne pepper
How To Make Bloomin Onion Sauce
- Pick a good bowl: Not a huge one to be honest. Just something small and solid that makes you feel like you’re making something real.
- Dump and stir: Add everything to the bowl. Stir until smooth — nothing wild. You’re not trying to whip air into it, just mix it gently.
- Let it chill: Wrap it up and stick it in the fridge for 30 mins. Trust me, the flavor gets way better after sitting.
- Serve however: Fries, onion rings, nuggets — it works with everything. Even spoonfuls straight if you’re into that.

Tips for Success
- Use prepared horseradish — not the creamy kind
- Let the sauce sit at least 30 minutes for best flavor
- Stir before serving — it can separate in the fridge
- Adjust cayenne if you want more or less heat
Storage and Reheating
- Fridge: Keep in a sealed container for up to 5 days. Stir before using.
- Reheat: Nope. It’s meant to be served cold or cool. Just stir it up and you’re good.
Frequently Asked Questions
- Can I use Miracle Whip instead of mayo?
Well technically, yeah. But the flavor will be tangier and sweeter — not quite Outback-style. - What if I don’t like horseradish?
Use a little less or swap in a small amount of Dijon for bite. But honestly, horseradish makes the sauce. - Can I use fresh garlic instead of powder?
You could, but it’ll change the vibe. Garlic powder keeps it smooth and mellow. - Is this the same as Outback’s exact recipe?
Not officially, but it’s very close. Tastes like the real deal. - How long do I really need to chill it?
30 minutes minimum. If you can wait an hour or more, even better. Overnight? Chef’s kiss.
Common Mistakes and How to Dodge Them
- Using too much horseradish: Start with 1 tablespoon if you’re unsure. You can always add more, but you can’t un-zing it.
- Not chilling it long enough: The spices mellow and blend after a rest. Straight outta the bowl? Kinda harsh.
- Forgetting to stir before serving: Separation happens — it’s normal. Just stir it back to life.
- Overdoing the cayenne: A little goes a long way. This sauce is about balance, not chaos.
- Using low-fat mayo: Makes it watery and sad. This isn’t the place to cut corners.
