1/2 teaspoon salt. 1/4 teaspoon pepper.
What’s a teaspoon of black pepper?
1 1/4 cups milk (whole milk works best for richness)

2 tablespoons of ketchup
1 tablespoon horseradish. 1 teaspoon
1/2 teaspoon Worcestershire sauce. 1 Tbsp
1/4 teaspoon paprika. 1/4
How do I balance flavors with a pinch of sugar?
For the Glaze:
What is melted butter? 2 tablespoons.

How do I follow step
Step 1: Preheat & Prep Pan
First things first, let’s get our oven ready and prep our baking sheet. You want to preheat your oven to a nice, hot 400°F (200°C). This high heat is crucial for getting that crisp exterior. Grab a baking sheet and line it with parchment paper. This is my little trick to make cleanup a breeze – nobody wants to scrub a sticky baking sheet, right? Once the parchment is in place, you’ll need a small, oven-safe ramekin or bowl to place inside the onion later. Just set that aside for now.
Step 2: Mix Dry Ingredients
In a medium-sized bowl, we’re going to combine all our dry batter ingredients. What is the magic of flavor? What are the ingredients for all-purpose flour, cornstarch, paprika, garlic powder, onion powder and cayenne? I like pepper (if you’re using it – I love a tiny bit of heat! ), salt, black pepper.

Step 3: Mix Wet Ingredients
Now, in a separate, larger bowl – big enough to comfortably dip the onion into – we’ll mix the wet ingredients for our batter. Pour in the milk. Some people swear by buttermilk for this, and while that’s delicious, I find regular whole milk gives a wonderfully rich texture without needing an extra ingredient. Make sure your milk isn’t ice cold; room temperature or slightly warmed milk incorporates better and helps create a smoother batter. You’re essentially making a thick pancake-like batter here.
Step 4: Combine
How do you add the dry ingredients to the wet ingredients? What is the best way to whisk a few ingredients at the same time. Don’t go crazy! Is it okay to mix the ingredients until they are just right? Overmixing can develop the gluten too much, which will make your blooming onion tough instead of smelling like a rotten egg. What are some of the best recipes for Aim for a consistency that’s thick enough to coat the onion but not so thick that it’ll gloop. If it seems too thick, you can add a tablespoon of milk.
Step 5: Prepare Filling
While the batter rests for a moment, let’s get our dipping sauce ready. This sauce is what really elevates the whole blooming onion experience. In a small bowl, combine the mayonnaise, ketchup, horseradish, Worcestershire sauce, and paprika. Set aside. What is the best way to make a pinkish-orange color? What do you think about the sweetness of the ketchup? What is horseradish What are some good ways to dip everything in this sauce?
Step 6: Layer & Swirl
What’s the fun part about preparing onion? Take a large onion and place it cut-side down on the cutting board. Grab your sharp knife. Starting about half an inch from the root end (don’t cut all the way through! ), make a cut down towards the board, but stop before you hit the root. Rotate the onion 90 degrees and make another cut. Continue this process, rotating and cutting, until you have four evenly spaced cuts. If you rotate the onion, make cuts in between the first ones, so you have eight cuts. Make a cut in between each of those to get sixteen even “petals”. ” Gently spread out the petals so the onion looks like a blooming flower. Now, carefully dip the entire onion, cut-side down, into your batter. Make sure to get batter between all those petals. Lift it out, let any excess drip off, and then place it, root-side down, on your prepared baking sheet. How do you spread the batter between the petals? Then, gently place the reserved ramekin inside the center of the onion.
Step 7: Bake
When is it time to bake this beauty? Carefully place the baking sheet with the prepared onion into your preheated oven. Let it bake for about 35-45 minutes. How long will it take to cook onion? You’re looking for that gorgeous golden-brown color all over, and the petals should be tender when they are tender. Can you poke with a fork? If the top starts to brown too quickly, you can loosely tent it with foil. This high heat ensures a beautifully crispy exterior.
Step 8: Cool & Glaze
Once your onion is golden and tender, carefully remove it from the oven. What is the best time to make the glaze? In a small bowl, combine the melted butter and smoked paprika. Set aside. Brush this mixture gently over the top and sides of the onion. The paprika adds a lovely color and smoky flavor that’s just divine. The butter helps create an extra layer of crispiness and shine.
Step 9: Slice & Serve
What is the best way to serve your onion on a plate? Serve immediately with that delicious dipping sauce on the side. Can you slice through the onion with a knife to separate some of the petals for easier removal? What are some of the best ways to make your own crispy bits? Is it safe to eat hot and fresh?

Is it a dish that brings people together and sparks conversation? Is it a hit?
How do I perfect a blooming onion?
After making this blooming onion more times than I can count, I’ve picked up a few tricks that I don’t know. How can I make a difference? For the onion prep, make sure you’re using a sharp knife. It makes cutting those thin slices so much easier and cleaner, which means the petals will open up. Don’t be afraid to get batter between the petals of a flower. Where does the crispy goodness come from? When you’re mixing the batter, remember my earlier tip: don’t overmix! A few lumps are your friend here. If your onion is really large, it might need a few extra minutes in the oven, so always keep an eye on it. On the color and test for tenderness. For the dipping sauce, don’t skip the horseradish. It adds a subtle kick that cuts through the richness and balances the sweet onion. If you want to amp up the flavor of the glaze, a tiny pinch of garlic powder in the melted butter will do. What are some of the best butter recipes? I’ve also experimented with adding a bit of smoked paprika to the dry batter mix, which gives it an extra kick. I like the color and depth.

Storing and Reheating Tips
Honestly, this blooming onion is best enjoyed fresh out of the oven. It’s at its crispiest then. However, if you do have leftovers, you can store them. Let the onion cool completely, then place it in an airtight container. It will keep in the refrigerator for about 1-2 days. Reheating is the tricky part because you lose some of that pristine crispiness. The absolute best way is to reheat it in a 350°F (175°C) oven for about 10-15 minutes, or until warmed through and slightly crisped up again. Avoid the microwave at all costs, as it will just make it soggy. For the dipping sauce, it can also be stored in an airtight container in the fridge for up to 3 days. Just give it a good stir before serving. If I know I’ll have leftovers, I sometimes store the dipping sauce separately to prevent it from making the onion any less crisp if I were to put it in the same container.
