Longhorn Bloomin’ Onion “Texas Tonion” Recipe

If you’ve ever craved a crispy, flavorful bloomin’ onion like the ones served at Longhorn Steakhouse, you’re in luck!

They call it the “Texas Tonion” and you’ll be amazed at how simple it is to achieve that perfect crunch just like they do.

Start by selecting a large, sweet onion; slicing it just right is key to those beautiful, golden petals.

Heat your oil to a precise 375°F for the best results.

One trick I love is to double-dip the onion in the batter to make it extra crispy.

Don’t forget to pair it with a tangy dipping sauce to complete the experience!

How to Make Longhorn Bloomin Onion Recipe

longhorn steakhouse texas tonion feat

Ingredients

  • 1 large Onion
  • 2 cups Flour
  • 1 cup Buttermilk
  • 2 Eggs
  • 1 cup Water
  • 1 tsp Paprika
  • 1 tsp Garlic Powder
  • 1 tsp Cumin
  • 1/2 tsp Oregano
  • 1/2 tsp Thyme
  • 1/2 tsp Cayenne Pepper
  • 1/2 tsp Salt
  • 1/2 tsp Black Pepper
  • 4 cups Oil (for frying)

Step-by-Step Instructions

Step 1:

Trim about 1/2 inch from the top of the onion and peel the outer skin.

Step 2:

Flip the onion, root-end up, and make slices starting about 1/2 inch from the root down to the cutting board to create petals.

Step 3:

Mix the flour, paprika, garlic powder, cumin, oregano, thyme, cayenne pepper, salt, and black pepper in a bowl.

Step 4:

In a separate bowl, whisk together the buttermilk, eggs, and water until well combined.

Step 5:

Dredge the onion in the flour mixture, ensuring all parts are well coated. Dip the onion into the wet mixture, then back into the flour mixture for a second coating.

Step 6:

Heat oil in a deep fryer or large pot to 375°F. Carefully lower the onion into the oil, cut-side down, and fry for 10-15 minutes until golden brown and crispy.

Tips and Tricks for Making This Recipe

Choosing the Right Onion

Use a large, sweet onion like Vidalia for the best results. Sweet onions have a milder flavor and hold up well during frying.

Achieving Perfect Petals

When cutting the onion, make sure the knife goes through each slice evenly. Consistent cuts result in uniform petals that fry more evenly.

Double Coating

Dipping the onion twice in the flour mixture ensures a crispier texture. The second coating sticks better, giving you that iconic crunch.

Oil Temperature

Maintain an oil temperature of 375°F. If the temperature drops too much, the onion absorbs more oil and becomes greasy.

Draining Excess Oil

After frying, place the onion on a paper towel-lined plate. This helps drain any excess oil and keeps the Bloomin onion crisp.

What to Serve with Longhorn Texas Tonion

French Fries

Serve your Longhorn Bloomin Onion with a side of crispy French fries!

The salty crunch of the fries pairs wonderfully with the flavorful onion.

It’s a classic combination that’s always a hit.

Coleslaw

Add a refreshing tangy coleslaw to your meal.

The creamy, crunchy salad contrasts nicely with the deep-fried onion.

It’s also a great way to add some veggies to your plate.

Grilled Asparagus

For a healthier option, try serving grilled asparagus.

Lightly charred asparagus has a lovely smoky flavor that complements the onion perfectly.

Drizzle with some olive oil and a sprinkle of sea salt.

Cornbread

Warm, buttery cornbread can be an unexpected but delightful side.

Its sweet and savory taste aligns well with the bold flavors of the bloomin onion.

Consider adding a touch of honey butter on top.

Macaroni and Cheese

Serve your onion with a side of creamy macaroni and cheese.

Rich, cheesy pasta pairs excellently with a crunchy appetizer.

It’s comfort food at its finest and can balance out the spices in the onion.

Variations and Substitutions

Take it up a notch with additional seasonings

You can add a dollop of barbecue sauce to your Texas Tonions copycat recipe for a smoky twist.

Incorporate fresh herbs like chopped dill or chives for a vibrant burst of flavor.

Exploring options with ingredients

Use Greek yogurt instead of mayonnaise for a tangier and healthier alternative.

Switch out regular paprika with smoked paprika to bring an earthy depth to your sauce.

Heat it up or cool it down

Add a splash of hot sauce to turn up the heat.

Include a bit of honey to balance the spice with a sweet undertone.

Texture and consistency adjustments

Add lemon juice for a zesty kick and a smoother consistency.

Stir in Worcestershire sauce for more complexity and depth in your sauce.

How to Store Leftover Longhorn Bloomin Onion

Using proper storage techniques can keep your Longhorn Bloomin Onion delicious even after your meal.

First, let the Bloomin Onion cool completely before storing to avoid condensation.

For optimal freshness, wrap the Bloomin Onion tightly with plastic wrap or aluminum foil.

Airtight Containers

Place the wrapped Bloomin Onion in an airtight container.

This helps maintain its flavor and texture.

Refrigeration

Store the container in the refrigerator for up to 3 days.

Make sure the temperature is consistently at or below 40°F to prevent any spoilage.

Freezing

For longer storage, consider freezing the Bloomin Onion.

First, flash-freeze it on a baking sheet for an hour before transferring it to a freezer bag.

This prevents clumping and makes reheating easier.

Common Mistakes to Avoid

Not Cutting the Onion Properly

It’s easy to mess up the cuts when slicing your onion.

Make sure to leave about half an inch uncut at the root to keep the layers connected.

Use a sharp knife and make clean, even cuts to get those perfect onion petals to bloom!

Skimping on the Soak Time

Don’t rush the process by soaking the onion too briefly in the batter.

Let it soak for a full 10 minutes to ensure it absorbs all the flavors.

This will help your onion turn out more flavorful and evenly coated when fried.

Overcrowding the Fryer

Putting too many onion pieces in the fryer at once is a big no-no.

Fry in small batches to avoid lowering the oil temperature, which leads to soggy onions.

Give each piece enough space to cook evenly and come out crispy and golden!
